Desperate Night

At 12 o'clock noon, the sky was dark. He carried a thick stone slab that had just been polished and walked to the front door of the stone fort. He gently put it down and stood it upright, fitting the position of the entrance.

"This is the gate wall in front of the gate." He patted the seven or eight meters high thick stone slab. The bottom of the stone slab was inserted into the foundation, and the two sides were fixed by the stones that Lao Li and Lao Zhou brought in time to fix and stabilize it. It was immediately stable.

The entire stone fort was completely completed at this point.

This is a gray-white stone fort in the shape of a rectangular block. It looks a bit simple and primitive on the outside, but because a large number of whole stones are used, it is very strong. And the load-bearing stone pillars inside are all complete stone pillars made by Yu Hong with his bare hands.

He first chiseled out a large piece of thick stone slab, then cut the stone slab into stone pillars, and then dragged it over with his bare hands and erected it, filling the gaps in the middle with small stones and silt.

Of course, these are just auxiliary pillars. The largest load-bearing stone pillar in the real stone fortress is more than two meters long and wide, and seven or eight meters high. It is built with large stone bricks.

This is the work of Lao Zhou and Lao Li.

"It's done! The next step is sealing. You guys take care of these. Make two more wooden ladders to use alternately. I'll solve the problem of air purification."

Yu Hong stepped back a distance and looked at the newly built stone fortress.

The stone fortress is just over eight meters high, and its length and width are more than ten meters. The whole is like a big cube, standing in the middle of the inner courtyard, occupying most of the area of ​​the inner courtyard.

The original wooden houses in the yard were demolished and merged into the stone fortress, and new wooden rooms were built inside.

Because part of the reconstruction relied on stone walls, the materials of the wooden house were redundant. Lao Li and his team also built two more rooms, a total of five rooms.

Inside the stone fortress, except for the load-bearing stone pillars, there is nothing in the two-story hall.

Bedrooms were built in the second-floor hall. These wooden rooms occupied a small part of the space, and a small amount of space was left as a public area.

The first-floor hall was completely reserved for the layout of breeding rooms, toilets, exercise rooms and other functional rooms.

The light bulbs that Yu Hong had accumulated before were put to good use. There were lamp posts hanging in the public areas on each floor.

The water pipes were also temporarily used by the public. Lao Li even considered the design of the drainage system.

Yu Hong admired the stone fortress for a while, and watched the others temporarily dilute the negative mood brought by the abandonment of the pyroxene mine because of this major event.

He returned to the cave and looked at the countdown of the enhancement. There was still one day to complete the enhancement of food.

So he simply sat cross-legged in the basement and quietly thought about the next development direction.

‘After the radiation grenade and air purifier are enhanced, I need to further enhance the strength of the black lizard and black wind defense array’

‘This time I can test my last idea, using the method of synthesis to add new materials to continuously enhance a thing. ’

Theoretically, the black seal cannot strengthen an already strengthened object, but if new materials are added and the synthesis is changed, this mechanism can be bypassed.

This time, in order to greatly improve the defense power, Yu Hong intends to do an extreme strengthening.

The so-called extreme strengthening is to strengthen things to the limit that can be achieved at the cost of consuming all of one's physical strength and energy.

Just like the original silver rune formation, this is how it came about.

As for the black lizard and the black wind defense formation, he was a little hesitant about which one to strengthen first.

‘If the black lizard is strengthened, the flexibility and mobility can be expanded, and even the safety area of ​​the entire camp can be expanded. But the black lizard is not suitable for dealing with a large number of opponents. Last time the speed man attacked the camp, it was of no use. ’

‘And strengthening the black wind defense formation can strengthen the absolute safety of the existing camp. This formation is very targeted at dense black disasters. Last time, it played a key role in dealing with a large number of ghosts driven by the speed man. ’

After thinking about it, Yu Hong decided to strengthen the formation first.

First ensure the safety of the foundation, then talk about other things.

Extreme strengthening is destined to take a long time. The only thing that can support it during this period is to rely on radiation grenades and existing black lizards, as well as oneself with internal energy.

At this time when the defense power drops sharply, Yu Hong’s only hope is that there will be no new high-risk black disasters!

Otherwise, the current camp will be in trouble.

The sky is gloomy and gray.

That kind of gray is not a pure color, but a dirty black gray that can never be washed away, as if it is a rag that has been used for a long time, repeatedly stained by countless stains.

In the north of Donghe, on the endless Qinchuan Plateau, the vast loess is also stained with a thin layer of gray by the gray of the sky.

Between the layers of the earth that are like skin wrinkles, stands a huge fortress built entirely of gray concrete.

The top of the fortress is blocked with high-strength synthetic glass to block rain and snow.

Inside are gray buildings built together.

Buzz.

With a buzzing sound, a huge door appeared on one side of the fortress wall.

A team of survivors, wrapped in pyroxene blankets and holding wooden sticks as crutches, walked into the door slowly and with difficulty, and were inspected by layers of fully armed security personnel inside.

At the end of the inspection checkpoint, on the roof of a five-story building, two tall men were standing and looking down.

Both of them were wearing full sets of bulletproof suits, which were not available on the market, and there was a mark of Aurora Laboratory in the corner.

Their faces were covered in thick dark red helmets, and their expressions could not be seen.

Only the suit, which was as thick and bulky as a bear, gave people a strong sense of oppression.

"Has the communication not been restored yet?" the shorter man asked in a low voice. "We don't have much time. On the satellite observation cloud map, there are a total of four high-risk black disasters, and two of them are already approaching here."

"Commander, the area affected by the evil code is too large. Although we have temporarily recovered, other strongholds may be caught off guard and attacked." Another person answered respectfully.

"How many more Donghe strongholds can be determined now?" The man called the commander asked again.

"Before the outbreak of the high-risk black disaster, there were seventy-four, but now according to the special drone radar scan, there are only forty-two. The main reason is that after the upper class moved to New Aurora City, they took away too many kinds of materials and weapons, causing the defense line to Collapse early, too many casualties," another person replied.

"Based on the results of my last communication search, have you found the underground nuclear base where Guan Cao is located?" the commander spoke again.

"It has been found. According to detection, the red value radiation concentration inside has reached more than 800. With this concentration, it is impossible for anyone to survive."

This answer silenced the commander.

He has very few friends. As the people around him become more and more afraid of him, as his position becomes higher and higher, and as his body changes become more and more serious, it has even exceeded the predicted progress of the laboratory.

Now, no one in the entire stronghold dared to raise his head and talk to him.

Guan Cao and Wei Song were his only friends, and now, one of them has disappeared.

"What about Yu Hong? The location of Baiqiu Village has been determined. Can you contact him?" He paused and asked again.

"I'm afraid not, that side is currently covered by the high-risk black disaster speed people. Not only that, but there are also high-risk insect people nearby. As you know, the insect people are the most dangerous among the eight-level high-risk people. Type, they tend to live in groups, similar to multi-eyed birds," another person quickly replied.

"As soon as possible. Yu Hong from Baiqiu Village has mastered a lot of precious information. He should be a top research talent at the same level as me. Let the laboratory produce more extracts. If it doesn't work, we will force it forward. It's just too much. Dead spot," the commander said solemnly.

"However, the existing bait material extraction output has reached its limit. If there are more, I am afraid that it will not be able to hold on." Another person said this.

"It doesn't matter. If you don't have enough, just keep grabbing more. In this world, as long as they can survive, many people are willing to do anything." The commander suddenly raised his head and looked outside the city in the distance.

On the yellow-grey land in the distance, a group of survivors were riding motorcycles. Their tattered pyroxene blanket cloaks were being pulled by the strong wind, making hunting noises.

This is a group of survivors numbering around twenty. They have pyroxene blankets, weapons, equipment, food, and drinking water.

It was obvious that this was a group of people who had just escaped from the stronghold.

But they were running for their lives.

Two vague human shapes made of gray and black insects were chasing after them quickly.

puff.

Suddenly, a human figure suddenly moved forward, its body spread out, and turned into flying insects, which instantly pounced on the two people on the motorcycle.

The two screamed, and their bodies were like balloons, rapidly expanding and getting bigger, and then.

Bang! !

The two of them exploded in just a few seconds, and a large number of small black and gray insects the size of gravel flew out of their bodies.

These little bugs soon formed a new bug man.

"The insect man is here, close the door." The commander said calmly. "Let the blood lead the ninth team out, and bring the expulsion fluid to lure them away."

"Everyone in Team 9 is dead, Commander."

"Then it will be Team 8. You will reorganize Team 9 from the newcomers in a while." The commander said calmly, "If you want to get food, water, and medicine, you have to risk your life."

Yu Hong watched the food box carefully as the countdown was about to end.

In the wooden box used to store dried meat, mushrooms and wild vegetables, the dark red countdown was just one minute away and was about to end.

Ahem

Yu Hong himself suddenly couldn't hold it back and coughed twice.

His throat suddenly felt dry and itchy, which made him frown, feeling something was wrong.

‘Even I can’t bear it? This air.’ I thought I didn’t need to wear a breathing valve, but I didn’t expect that now

At this moment, the wooden box suddenly blurred for a moment.

When it became clear again, the food inside had changed drastically.

The same nutritional cream as before was placed in a wooden box, with a thin blue plastic sealed package outside.

There is an instruction label on the surface as usual.

Yu Hong picked it up and looked at it.

‘Nutritional paste: also known as comprehensive multi-functional meal replacement paste, adults only need to take one tube a day to supplement all the required nutrients. ’

"It's done." He breathed a sigh of relief and quickly counted. There were six hundred sticks in the box, which was just the right amount and could feed six adults for three months.

After converting the materials before strengthening, one month's worth of food can be strengthened for three months.

‘Next, it’s time for the air purifier. ’

I'm sure there's nothing wrong with the nutritional ointment. I guess Black Seal copied it from somewhere.

Yu Hong quickly came to the air purifier.

The stone castle was built, the food crisis was temporarily solved, and the air problem was immediately dealt with.

He reached out his hand and pressed it on the purifier.

‘Strengthening the purification system, direction: filtering and detecting substances harmful to human body in the air, especially special substances in the outside air that cause people to cough’

Yu Hong didn't know what caused the cough, but he planned to give it a try and pointed the black seal directly at the thing. As long as the air problem could be solved as soon as possible, he could start his extreme strengthening plan.

After all, the formation was the core support for the safety of the camp.
