Into Unscientific

Chapter 183 The Treasure in Nanako's Lair (7.4K)

After greeting Old Soda who was in the next room.

Xu Yun put the phone in his trouser pocket and locked the door.

left his residence.

Twenty minutes later.

University of Science and Technology East.

"Longitude 117.2764 Latitude 31.8392"

Xu Yun drove the longitude and latitude positioning software, hummed a little tune, and walked slowly along the trail in the school.

He looked around as he walked, and seemed to be looking for the exact spot.

have to say.

The level of science and technology in these years has indeed developed to a level that is very convenient from the perspective of a commoner.

Even with the free latitude and longitude software, the positioning can be locked to five or six decimal places.

However, no matter how accurate the software is, it has a range after all, and the coverage area implemented on the ground is still quite large.

"117.2754117.2756 found, 117.2764!"

After locking the line of longitude.

Xu Yun was not in a hurry to determine the latitude line, but glanced around first.

At this time, he was located in the east of the East Campus of HKUST, which is near the water lecture hall.

At two o'clock on his right hand side is the soul hinterland of HKUST:

Guo Moruo Square.

That is, the core main battle area where the cockroaches were disinfected at the beginning, and millions of cockroaches were eliminated.

And at seven o'clock behind him is Building No. 14 where Chang Licheng and the others are located:

It was the mistakes of Chang Licheng and Ye Guohong that led to the first wave of cockroach riots and the subsequent live broadcast of disinfecting cockroaches.

In a sense.

That could be the root of all evil.

Then Xu Yun raised his head and glanced at the sky.

After confirming that it would not rain in a short time, he continued to search for the target along the latitude.

"Archives Floor 215.216"

He walked all the way like this, passing several more conspicuous buildings one after another, and the latitude on the software was constantly approaching the target.

"31.8372"

"31.8384"

"31.8388"

"31.8392"

Fifteen minutes later.

Xu Yun stopped at a location very close to the southeast gate of the East Campus:

This is a small sports field composed of basketball courts. Fifty meters to the east across the avenue is the Frontier Research Center of Earth and Space Science.

To the west is the East District Physics and Chemistry Building.

This moment.

In the basketball court, several boys were playing half-court 3V3, and there were seven or eight substitute players sitting around them, and three of them were wearing short sleeves.

To know.

It is now the end of December, and those who dare to wear short sleeves are warriors.

The competition on the basketball court was fierce, but Xu Yun had no desire to watch the match.

"It's weird"

He just stood on the sidelines and observed the center of the field for a while, but he didn't find anything that could match the word 'reward' in the slightest.

The reward can't be a ball, can it?

Or the basket?

Then Xu Yun pondered for a moment, then looked around.

Maybe what the piece of paper gives is not a certain point, but an area?

On the right side of the basketball court is Southeast Gate Avenue, and the flow of people at this time is neither too much nor too little.

Sparsely, there is only one person every seven or eight steps.

The trees on both sides of the road were cut back in advance because of overwintering.

The trunk of the tree is also wrapped with hemp rope - this is a measure to keep warm and prevent frostbite, and at the same time reduce insect infestation.

Everything is fine on the right side.

Xu Yun's brows tightened even more, and his eyes turned to the left again.

Fifty meters away from the left side of the basketball court is the Physics and Chemistry Building in the East District. The area between the basketball court and the basketball court is even more empty than Southeast Gate Avenue, and several faculty cars are parked desertedly.

Other than that.

There were only a few construction workers who seemed to be repairing the sewer, and nothing else was left.

Um?

etc? !

Looking at a worker who just went down the well, Xu Yun suddenly had a flash of lightning in his heart:

yes.

I can't find the reward on the ground, so could it be underground?

Judging from all the past performances of Halo.

It may pretend to be mysterious, and it may surprise or frighten people suddenly.

But never an error.

That is to say

The reward is likely to be below the ground!

Of course.

Theoretically, the sky and even outer space are also possible, but the probability is not high to be honest. The significance of mentioning the sky is greater than the actual possibility.

And just as Xu Yun was thinking, a shout suddenly came from his ears:

"Eh, God Xu?"

Xu God.

After staying in the Northern Song Dynasty for a year, this was the first time Xu Yun heard this title.

So he subconsciously raised his head and looked in the direction of the voice:

The speaker was a girl in a white coat, not very tall, with a ponytail.

At this time, the girl was standing on the edge of the sewer, with her toes on her toes, waving her hands with a flying face.

Xu Yunjian was slightly taken aback, and while waving to the other party, a name quickly came to mind:

Guo Yuting.

This is a student from the Department of Biology. She is currently a sophomore with good grades and has never missed a scholarship.

Guo Yuting once helped Xu Yunyan when he was in the second year, she is a very hardworking little girl.

Meeting an acquaintance by chance, Xu Yun temporarily put aside the thoughts in his heart.

He walked quickly to Guo Yuting, nodded to the other two boys who were also wearing white coats, and asked Guo Yuting:

"Xiao Guo, what are you?"

Guo Yuting immediately gave him a look of 'you have to blame', spread her hands, and said:

"Isn't that God Xu, you showed your power a while ago, arbitrarily arbitrarily disinfecting all the cockroaches in the eastern district?"

"Later, the school considered that although cockroaches store cockroach eggs through egg sheaths, sometimes they also lay eggs in settlements. In addition, during the poisoning period, the opening and closing of egg sheaths and sexual @organs are stimulated. A lot of insect eggs were left in the ground."

"So the school organized a professional disinfecting team, and by the way, conducted a comprehensive screening of the drainage pipes along the way, which can be said to kill two birds with one stone."

"And us unlucky bastards"

Speaking of this, Guo Yuting couldn't help but sighed, and pointed to the ground:

"Naturally, I came to collect soil samples."

"."

The corner of Xu Yun's mouth twitched a few times, feeling that the juniors in front of him instantly turned into creditors

In fact, think about it.

The actual cost of the previous disinfecting organized by Xu Yun may not be particularly high, but the various sunk costs and risk costs are not low at all.

So after making big news.

The University of Science and Technology will naturally take advantage of his illness to kill him, and chase him to his lair to kill the grass and roots.

In order to avoid future troubles in vain, it will be a waste of work in the end.

At the same time, since it is necessary to disinfect the cockroach eggs, Ke Nature will not let go of the good opportunity of sampling.

After all, the high-density wild cockroach living soil is easy to say, but it is more troublesome to find.

Especially this kind of cockroach nest that has accumulated for several years or even more than ten years is disgusting, but the research value is really not low.

Like coffee beans.

At present, there are more than 4,000 ppm-level substances in a coffee bean, and more than a thousand of them do not know what they are, but they only know that there is such a thing.

The same reason.

It is conservatively estimated that a fist-sized piece of cockroach nest soil can contain tens of thousands of special substances. Maybe we can really find something?

Therefore, from an academic point of view, this approach is obviously no problem.

But this way.

It's hard for Guo Yuting's juniors in the biology department.

Looking at the resentful juniors, Xu Yun quickly put his hands together:

"I'm sorry, I'm sorry, how about it, my research group happened to be looking for someone to help count some ordinary documents on the weekend."

"An hourly salary of 25, eight hours a day on weekends, including a meal at noon, are you willing to come?"

Guo Yuting and the three of them immediately frowned when they heard the words:

"real?"

HKUST enrolls only 2,000 students each year, and quite a few of them are born in low- and middle-income families, and their monthly living expenses are only 800-1,200.

Therefore, in HKUST or most of the C9 universities, it is normal to go out to work part-time on weekends.

The hourly salary of a part-time job in Luzhou is generally 8-12 yuan, and some of the better ones can reach 15 yuan.

No matter how high you are, there are only jobs like tutoring or doll clothes, which are hard to come by.

You can get an hourly salary of 25 yuan for counting documents in the laboratory, and even if you only work for a weekend, you can get 400 yuan into the account.

For Guo Yuting and others who were born in ordinary families, this is undoubtedly a very generous sum of money.

So soon they put aside the resentment that was a bit of a joke, and began to know everything about Xu Yun.

Of course.

Giving this kind of 'high salary' is not Xu Yun's generosity or squandering of funds.

According to the requirements of HKUST.

The hourly salary for normal BSL-3 laboratory statistics starts at 25 yuan, but Qiu Sheng has been in charge of this before.

After appeasing the emotions of several juniors, Xu Yun asked again:

"Xiao Guo, have you collected any samples this morning?"

Guo Yuting nodded, pointed to a small airtight box beside her, and replied:

"We just came from the entrance of the pipeline on Kaizhen South Road and collected a total of four samples."

"The shallowest one is 1.5 meters from the ground, and the deepest is nearly ten meters. They are all large cockroach nests."

Xu Yun nodded slightly, then pointed to the mouth of the well in front of him and asked:

"And this one?"

"This one"

When Guo Yuting heard this, her expression became a little more serious:

"It's not long since we arrived here. The water was poured and the groove was opened more than ten minutes ago. Now the master in charge of pipeline maintenance is checking the situation underneath."

"If the pipeline is okay, we'll look for a suitable node to collect soil samples, though."

Xu Yun glanced at her and asked:

"But what?"

Guo Yuting gestured around, pointed to the southeast gate, and said:

"However, unlike other nodes, this node is the largest and oldest sewage discharge node of HKUST."

"During the eradication of cockroaches, the number of cockroaches emerging from this area was the largest."

"Therefore, if there is no accident, there should be a very large cockroach nest below, or the largest gathering point of cockroaches in HKUST."

"Lair?"

Xu Yun blinked, with a thoughtful look on his face.

Although in reality it has only been less than a month since the cockroaches were eliminated.

But for him, the actual time span has exceeded one year, and some details have long been forgotten.

But when Guo Yuting said this, he also remembered such a thing:

Back then, the main battlefield for cockroach extermination was located in Guo Moruo Square, and the largest cockroach army during that period seemed to have indeed emerged from this area.

Could it be that the reward given by the halo

Is it still related to the previous cockroach?

Xu Yunjian was silent for a while, pointed to the basketball court not far away and said:

"Xiao Guo, has the pipeline at the head of this well passed the basketball court?"

Guo Yuting glanced in the direction of the basketball court, shook her head and said:

"I can't remember clearly. After all, I can't understand the construction drawings. I just remember that there are three nodes here."

As a result, before Guo Yuting finished speaking, a voice with a Northwest accent came from beside her:

"There is a pipe under the basketball court, and it's still a medium-sized sewage pipe."

Xu Yun and Guo Yuting turned their heads together, and found that a maintenance technician was climbing out along the ladder at this time.

The words above came from this mouth.

After the sword repairer came up, Xu Yun took the initiative to hand him a cigarette - Xu Yun himself does not smoke, but he is used to bringing a pack of cigarettes just in case:

"Master, is there anything abnormal in that pipeline?"

"Tsk tsk, Yuxi, thank you buddy."

The overhauler took off his gloves, took the cigarette, and pinned it to his ear, then said:

"Abnormal? Nothing unusual, it's just that the smell of a section of the pipeline is much weaker than other areas."

Xu Yun suddenly became interested:

"The smell is much weaker?"

The overhauler nodded, stretched out his calloused left hand and pointed to the manhole cover:

"The pipes under the basketball court are all 1800 gauge, which is 1.8 meters, and there are several 2400 and one 3000 external main roads in front."

"There is a section of it. Oh, it's almost under the basketball court you mentioned. The smell is a little weaker than the surrounding area. I'm thinking that it may be related to the fact that there is less silt and garbage."

The repairman also laughed as he said:

"After all, it is a sewage pipe. There is water flowing, and the amount of garbage stored in each node must be different."

As the saying goes.

The speaker has no intention, but the listener has the heart.

Xu Yun is not a student of urban planning or engineering design. If he heard this sentence in normal times, he would probably believe it with a vague nod of his head.

But today is different.

Xu Yun is very clear that there must be something abnormal in the area of ​​the basketball court:

Either the air in the sky is special, or there is something under the ground.

Under this premise.

The overhaul master said that the smell in that area was weaker, how could it not make him think deeply?

Then Xu Yun thought for a while, turned his head, and asked Guo Yuting:

"By the way, Xiao Guo, how did you conduct soil sampling?"

Guo Yuting bent down, took out a form from the backpack on the ground, and handed it to Xu Yun:

"If there is silt on the inside of the pipeline, it must be scraped. If there are obvious cockroach clusters near the pipeline—for example, a large number of cockroach excrement is detected, you can fill out this form and report to the engineering team. Quantitatively dig down with a drill.”

"Wait to dig to a certain depth, and then go to sample the soil."

"The school has given a lot of strength this time. After all, this kind of specimen is really hard to come by."

Xu Yun nodded clearly, almost understanding the process of Guo Yuting and the others.

Anyone who loves cockroaches should know this.

The excrement of cockroaches contains an ester substance called ezoria, which can be determined by specific NAC test paper.

And the higher the concentration, the faster the reaction, and the detection is still very simple.

Therefore, Guo Yuting and the others' procedure is to scrape the mud if they can, and put on the test paper if they can't.

After measuring the activity traces of a large number of cockroaches, you can go to the excavator to toot,

Large sewage pipes should not be more than 0.7 meters away from the ground, and the depth of pipes in colleges and universities is generally between 1.5 and 5 meters.

The largest external main pipe is about 3-7 meters, which varies from school to school.

This kind of depth is not very deep, and it can usually be achieved by a car with a drilling rig. The key is the skill of the pilot.

Although in this way, the cost must be higher than that of pure manual drilling.

But as Guo Yuting said.

A situation similar to HKUST, where 99.99% of the cockroaches have been wiped out, leaving only the old nest that has not been ransacked, is almost a rare spectacle that has not been seen in decades.

In the face of possible returns, what is the cost of digging?

Therefore, at the school level, HKUST has a lot of support for soil sampling.

Then Xu Yun thought about it, and a flash of decision flashed in his heart, and asked Guo Yuting:

"Xiao Guo, are you wearing protective clothing today?"

"protective suit?"

Guo Yuting was taken aback for a moment, then quickly replied:

"Yes, yes. Why, God Xu, are you planning to?"

Xu Yun nodded heavily:

"I'm going to go down and have a look first, and if it doesn't work, I'll go to the drilling rig—I always think there's something good down there."

Guo Yuting hesitated for a moment, turned her head and looked at the two companions, and said slowly:

"That's fine"

The maintenance engineer has checked the condition inside the pipeline, and the pipeline is also in a state of precipitation at this time.

Unless HKUST used to be called Hogwarts, and there was a secret room under a certain women's bathroom where there was a basilisk that liked to walk along the sewage pipes, Xu Yun didn't have any safety problems.

At the same time, based on Xu Yun's current influence in HKUST, there is no problem at all in mobilizing a drilling rig to cut first and play later.

So soon, Xu Yun changed into a set of protective clothing.

This set of chemical protective clothing is specially customized by the University of Science and Technology. It has good toughness and is of much higher quality than the common ones on the market.

Among them, the head area is a gas mask, which can filter a considerable part of harmful gases.

On the back of the chemical protective suit, there is an oxygen tube similar to the size of an insecticide-this thing is mainly for special situations, and it may not be used once in a hundred times.

There is also a simple tool bag on the waist, with tools such as wrenches and screwdrivers.

After everything is ready.

Wearing a searchlight on his head, Xu Yun went down the well alone.

There is a very famous sewer museum in Paris. The interior of the entire sewer is a tunnel-like arch, and there is a lot of space for adults to walk in.

The sewer of HKUST is somewhat similar to the Dejian sewer in Jiaoao, that is, it is a ∧ type, and it is one of the few universities in China that has a ∧ sewer.

After all, the University of Science and Technology was airborne and relocated to the center of Luzhou, so many supporting facilities are the top specifications in Luzhou.

Da da da--

Xu Yun was bending over slightly at this time, walking alone in this sewer.

He was at a depth of about five meters from the ground, and at this depth, the latitude and longitude software could still be used.

31.8381

31.8387

five minutes later.

Xu Yun stopped in his tracks.

At this time, his position is exactly the center of longitude 117.2764 and latitude 31.8392.

Then he thought of what the maintenance worker said, hesitated for a moment, and took off the gas mask with his hands.

as expected.

Although the pipes in this area are still filled with a damp and sour smell, it is at most the level of a street trash can.

It is far from the smell that a sewage outlet should have.

Then he still didn't wear a mask, and took a few steps back.

As a result, the front and back were only five or six meters away, and the smell in the pipe suddenly became foul.

Xu Yun returned to the original place, calmed down, and chose to move forward this time.

It was also less than six meters, and the stench intensified.

This is undoubtedly good news, which means that the area is further shortened, and it also means that the "reward" is getting closer.

Then Xu Yun turned on the flashlight and started searching seriously.

trash bag.

Chunks of raw meat.

Chicken bones.

Xu Yun's eyes swept over the residues one by one.

After a few seconds.

He stopped suddenly, and his eyes locked on the right inner wall of the pipe.

Only at this moment.

On the inner wall of this place, there is a group of green moss the size of a computer screen.

Xu Yun stepped forward and gently lifted it with his hand.

The moss didn't budge.

He had no choice but to take a step back, took out a small shovel from the tool bag on his body, and gently shoveled off a small piece of moss.

Then he put the moss in his palm and shook it.

After pondering for a moment, wearing gloves, he picked up a piece of minced meat from the ground.

This piece of minced meat was originally stuck in a certain gap, soaked in all kinds of sewage for a long time, and it has already completely rotted.

It looks as if it has been possessed by a demon, and at the same time it has an astonishing stench.

An unprepared ordinary person would probably vomit on the spot.

Then Xu Yun put the minced meat in the moss, wrapped the moss into a ball, and waited in place.

ten minutes later.

Xu Yun let go of his hand.

He took out the minced meat again, put it in front of his nose and smelled it carefully.

After a while.

His heart pumped heavily, and he missed a big beat:

This piece of meat, which originally had a strong stench, was wrapped in moss

The smell dissipated by at least two orders of magnitude!

That is to say

this piece of moss

It has some kind of purification effect!

As for sterilization, deodorization or other.

This requires a lot of research.

Actually.

What Xu Yun didn't know was.

The area he was standing in had been the most glorious time of the Cockroach Empire, and few cockroaches were willing to stay here.

Even Nanako is the same.

Because the rotten air has no place to stay here, it must be purified.
