Chong Sheng 1977Nian Cong Zhi Qing Kai Shi

Nanyi picked up an object that looked like a gold brick, put some weight in his hand, and pinched it with his nails. Although he didn't know the gold content, the gold was right.

However, it is more shocking, each gold brick is engraved with a pattern of orchids.

If Nan Yi read it correctly, this should be the Asahi Crane among the orchids, a unique orchid species in Japan.

Could Nanyi be wrong?

Won't.

Some time ago, didn't he just read books on orchids?

"Damn it, this gold has something to do with devils!"

Asahi Crane, Orchid, Guangdong Province, Guangdong, Guangxi, and Guizi, when these key words are put together, Nan Yi immediately thinks of the four devils' secret agencies, "Plum Orchid, Bamboo and Chrysanthemum".

The orchid should point to the orchid organ.

Didn't the Lanzhou agency managed by the little devil He Zhiyinger mainly target the Guangdong and Guangxi regions?

Nan Yi looked at the gold in the oilcloth, estimated the weight, and it was a little over 800 catties.

To say that the gold was used to buy a major officer of the Cantonese Army, this gift is obviously too big; but if it is used to buy a higher level, this gift seems too light.

Is this gold used by the devils to bribe people, or was it intercepted by the Cantonese army from the Lan organs?

Or is it part of the devil's search from Guangdong Province that year, and someone pocketed it?

No, Guangdong Province is close to the sea, and there are many outlets to the sea. The devils can easily transport away the gold, silver and treasures.

The Liu family are devils?

The son-in-law of the Liu family in the well is a devil?

Or was it a member of a private interest alliance among the devils at that time?

Back then when the devils ransacked the country, it was impossible for all the gold, silver and treasures to be handed over to the "Shan Lily".

But, how did this gold appear here?

Nanyi has one head and two big ones!

If he couldn't figure it out, Nan Yi didn't think about it anymore, no matter where the gold came from, it belongs to him now, this is an established fact.

Once the money is in his hands, Nanyi has no habit of spit it out.

Picking up a gold brick, Nanyi threw it out of the pothole. One piece after another, a total of 28 gold bricks were thrown out by Nanyi. People climbed out of the pothole, moved five or six yuan at a time, and moved all the gold bricks to the back house.

Then, I took a gold detector and swept the whole yard again, and I didn't hear any beeps again.

"Ruopin, come down." Nanyi walked to the edge of the courtyard wall and clapped his hands.

"Dad, I'm jumping off, you have to catch me."

"Let's jump."

Catching Nan Ruobing who jumped off the wall, Nan Yi patted her butt, "Little girl, it's heavy again."

"Not only have I gained weight, but I've also grown taller." Nan Ruobing murmured, and then asked, "Dad, have you gained anything?"

"Yes, about 700 catties."

"Wow, you're getting rich!" Nan Ruofing cheered, clapping her little hands.

"Don't get excited, it's less than ten million dollars."

"Huh? Ten million U.S. dollars, that's fifty million Hong Kong dollars, dad, is that much money?"

"Not much, the handsome guy you like may have so much money."

"Big handsome guy? Dad, you mean Chu Liuxiang?"

"yes."

"Oh, that's not much."

"It's not much, so don't get excited."

"Oh, Dad, I'm sleepy."

I don't know the size of the treasure that the little girl expected. Hearing that there is only such a small amount supports her excitement.

"Daddy will take you to bed."

Eight hundred catties of gold was not enough to gild the body of the Buddha. It was only used once, and the gold was transported from Shenzhengwan and deposited in the vault of the Xiangsong Branch of the Swiss Bank.

The Nanzhai also fell into a calm state. Nanyi didn't want to touch the two snapping turtles in the well yet.

He was afraid of discovering a valuable secret from the two turtles. If there were treasures worth billions or tens of billions waiting for him to dig, Nanyi couldn't guarantee that he could hold them.

But if there is such a treasure, can he keep it now?

Nanyi was still out of sight and out of mind, and it would not be too late to reopen the well when he could bear it.

Alas, money touches people's hearts, but money can also kill people!

...

"How many?"

"Dad, 3.72 meters."

"Oh, I'll remember it, and then measure the height of the threshold."

Nan Ruofing took a tape measure and leaned against the threshold to measure the height and width, and then leaned against the corner to measure the right angle, "Dad, the height is 32.5 cm, the width is 24.7 cm, and the right angle is 87.4 degrees."

"Positive or negative angle?"

"Of course it's a positive angle. I'd say 92.6 degrees for a negative angle."

"Oh, I see."

After Nanyi recorded the data, he climbed up to the top of the wall, took the tape measure off the belt, measured the width of the courtyard wall, and put the compasses on the drainage tiles to measure the curvature.

"Ruopin, come here and help me draw the ruler."

"oh."

Nan Yi pulled the tape measure and let the head of the tape hang down. Nan Ruofing pulled the head of the tape and pressed it to the ground. Nan Yi checked the height and recorded the number.

One morning, the father and daughter took measurements in the yard.

After lunch, Nan Ruofing didn't go to take a nap, but got together with Nan Yi to draw a three-dimensional picture of the yard.

Nanyi is not good at drawing, but he can use drawing tools to draw geometric figures, but he is very good at it.

"Dad, if the enemy comes in through the door, we can bury two bouncing betties here, and set a directional blast mine at this position; the bouncing betty sets the fuze delay, and the directional mine explodes first, pushing people to this position, and then the steel ball flies up, The lethality can be guaranteed to be maximum."

Nan Ruofing took a pencil, drew a few circles on the edge of the screen wall, and said.

"I learned this from Johnny?"

"Yes, Uncle Johnny likes me very much, he will teach me everything."

"Oh." Nanyi nodded and said, "Your method is very good, but what Dad wants is not to kill the enemy, but to record the appearance of the enemy.

What we need to place is the mechanism that triggers the camera, and calculate the position of the camera. The current hard disk storage space is not enough, otherwise we can consider using a camera. "

"Camera? CCD?"

"Almost, but CCD is usually used in still video technology, that is, digital cameras. This technology is not yet mature. The principle of the camera is actually the same as that of the camera lens. We can also consider setting up several cameras."

"Dad, how to trigger the recording device after the monitor hears the sound?"

"The principle is very simple. It is triggered by the decibel level of the sound. It's just that my father knows the principle but can't do it. This thing needs to be done by a professional."

"Oh, Dad, you don't understand either, then I'll ask Uncle Johnny when I get back."

"Okay, then Dad will leave this job to you, and you will design and produce it, okay?"

"Okay, I'll do it."

Nan Ruofing said with a stinking face.

Calculations, still calculations, need to calculate where people of different weights, heights, and gaits will probably step on when they walk into the courtyard door. Only by calculating the landing point can the trigger mechanism be installed in a suitable position...
