Zheng Fei wanted to take a good sip of tea, but he didn't tell him the origin of this tea just now.

At this time, he said with a little weakness: "It should ...... It should be the tea that the auction house auctioned, the good ones are millions, and the bad ones are millions. ”

A group of peers: "......"

Millions? So?

How could he say it?

Mao Zheng: "......"

Is this tea?

It's more expensive than gold leaves.

Mao Zheng clenched the jar in his hand in pain and rushed out of the door.

Everyone: "......"

At dinner in the evening, Mao Yuning always felt that her grandfather and her father were in a state of mind, and asked them what was wrong, but they just shook their heads and ate the food in the bowl blankly.

Zhan Yuxi gave her vegetables: "Your father, this is worried that his cabbage will be arched away, don't worry about him, let's eat."

Mao Yuning looked at her suspiciously, how could she not believe it?

One day when she wants to really get married, her father and grandfather are estimated to beat gongs and drums and put a flowing water banquet in the village.

Mao Yuning shook her head, leaving these messy things behind, she had one thing and needed the old man's help: "Grandpa, do we have a few family heirlooms in our family?" ”

The old man stopped eating and looked at Mao Yuning in surprise, he hadn't even mentioned this matter to his sons in the family, how did Mao Yuning know?

Mao Yuning had already thought of an excuse, and said with a smile: "When I was a child, I asked my grandfather for pocket money, and when my grandfather opened the iron box, I saw it." ”

Mao Zheng knew that the old man had an iron box, and he also knew that he liked to put money in it, but he never knew that there was a family heirloom in it?

The old man suddenly realized, nodded and said, "There are a few family heirlooms."

Mao Yuning showed a shy face: "At that time, I was curious, and I climbed the beam of the house and saw my grandfather's things." ”

Mao Zheng: "......"

Zhan Yuxi: "......"

Old man: "......"

When Mao Yuning was a few years old, Mao Zheng's brothers did not divide their families, and none of them built houses, and they all lived in the backyard of the martial arts hall of the big mansion.

At that time, the house I lived in was full of wooden beams, and the old man's iron box was placed on the beams.

It is said that Mao Yuning's cousins have climbed up, and they have never suspected that the youngest girl has done this.

At that time, when the old man caught someone, he would blow his beard and stare at him, pick up a bamboo whip and beat him up.

At this age, his temper has already softened, and when he heard Mao Yuning re-mention the old story and blew up the matter of climbing the beam, the old man couldn't cry or laugh for a while, his fingers tapped her hard, remembered something, and hesitated: "That iron box, your cousin can't open it, how did you open it?"

The old man's iron box was not locked, and the oldest mechanism was used to lock it, and Mao Yuning's cousins didn't know anything about this, so they naturally couldn't open it.

"The hidden buckle of the mechanism, when my grandfather made the lock, he told us that there is no lock in the world, any lock, only one key is needed to pry it open, and it is not a problem at all, although the lock is troublesome, except for himself, it is difficult to have a second person to solve it."

Mao Yuning's thumb and index finger were compared by a distance: "Grandpa's iron box is not a fingerprint of modern technology, and you need your own fingerprint to unlock it."

It takes a certain number of steps, the last step is the width of your thumb, and that position is topped up to touch the clasp.

At that time, my thumb was not as big as yours, and it was impossible to score it perfectly.

I usually secretly measured the size of your thumb and imitated a model, and in the last step, I used this model and opened the hidden button. ”

Mao Zheng didn't know anything about mechanical equipment, but he knew how difficult it was to unlock this kind of mechanism, so he looked at Mao Yuning dumbfounded for a while, and then turned his head to look at the old man.

The old man looked surprised, obviously he didn't expect that Mao Yuning would be able to unlock his lock.

In fact, Mao Yuning did not climb the beam of the house when she was a child, she was sensible and worry-free since she was a child, practiced self-discipline, learned self-discipline, and rarely did things to uncover the tiles in the house.

I know how to untie the old man's lock, or in a dream, after the old man passed away, he gave her those heirlooms, and when several uncles and uncles in the family liquidated the relics, they gave her this iron box.

After reading those family heirlooms, Mao Yuning studied the method of opening the lock of the iron box and opened the box, not because of the teachings of the young man.

Of course, it is precisely because the last method is not achieved that the lock is opened, but the lock is broken.

The old man was going to give her those family heirlooms, but seeing that she had this talent, he couldn't help but admire: "I made the lock myself, if I didn't teach it to open it by hand, it would be difficult for anyone to open it, but you can open it, it shows that you have outstanding talent."

He nodded in satisfaction.

Mao Zheng and Yourong nodded with honor, and said curiously: "What does Mao Mao want those books for?"

"There are a few friends who are working on weapons and equipment projects, and I happen to be interested in this......" Mao Yuning said halfway, put down the dishes and chopsticks in his hand, and went to the room to come out with a box.

The old man had almost eaten and walked to the living room.

Mao Yuning held the box and placed it on the table in the living room.

When Mao Zheng saw the things in the box, his face changed fiercely: "Mao Mao, this thing ......"

Mao Yuning hurriedly explained: "Their business is in cooperation with District J, grandpa, don't worry, this blank was brought out by me with my consent, and it will be handed back when the time comes."

Mao Zheng breathed a sigh of relief, but he still went out uncomfortably and locked the iron door outside the gatehouse.

Mao Yuning dismantled the billet instrument directly, and installed it fluently in front of the old man.

When she arrived at the snap ring on the right wing, Mao Yuning slowed down her movements, put on the two commonly used parts, put the blank in front of Mao Zheng and the old man, clenched her hands, pulled the wrench, and a crisp sound of 'pop' came, and the billet instrument trembled in her tiger mouth.

After Mao Yuning finished these movements, he looked at the old man and said: "These two parts are the most advanced and widely used parts on the market."

Mao Yuning took out two other models of parts and explained: "These two models were developed many years ago, and according to the research and development theory, their combination has ten times the minimum power of ordinary parts."

Mao Zheng's eyes widened in horror.

Those who practice martial arts are not afraid of people, they are not afraid of swords, they are afraid of such weapons.

The device in Mao Yuning's hand is ten times more powerful than the current technology, what kind of power is that?

He couldn't have imagined it at all.

The old man asked her to continue with a serious face.

"After this theory came out, many people organized teams to study and develop, and so far, no one has been able to confirm that this theory is valid, but in the data, no one can overturn it."
