The Three Kingdoms in the Ya Nei

Now, he is like a piece of emerald covered by stone layers, as long as the outer shell is broken and carved carefully, it will emit a dazzling splendor.

He made a few more cuts, stretched out his hand and pushed, and amidst the crackling sound, the thick yellow bamboo fell down with a loud crash.

He raised his hand to touch the sweat from his forehead, and chopped off all the twigs and leaves with a hatchet.Only then did he carry the hatchet to his back.Bending down and holding the big bamboo with only the main trunk under his ribs, he strode back.

Going all the way back to Qingyunju, threw down the hatchet and big bamboo, poured spring water into the house, wiped it a little bit, then picked up the small knife that was about an inch long, looked down, and walked out the door with a wry smile Come. [

"The length of Zhang Er... >

He walked around the yellow bamboo pole twice, put his chin on his hand and thought for a while, put down the knife, and picked up the machete again.After a little visual inspection, a hole was split from the root.

Put down the yellow bamboo and let the hatchet get stuck on it.After going to the house, I found three ropes and a piece of bamboo left over from building the house that day.

First use a rope and tie the two ends to the back of the knife and the handle of the knife respectively, then tie half of the bamboo to the front of the yellow bamboo firmly and fix it.Finally, use the longest remaining rope, tie one end to the midpoint of the rope tied to the hatchet, and the other end to go around the front end of the fixed yellow bamboo tied into a cross, and throw the end of the rope back... ...>

The sun was slanting slightly to the west, and he was concentrating on the work in hand, but he didn't notice the passage of time at all.

In the opposite room, Tong Yuan standing by the window quietly watched every step he made until he saw him bend down to pick up the thrown back rope, hold it with one hand, and use the reaction force to drag the hatchet all the way forward to break it. When he opened it, there was a flash of appreciation in his eyes.

Such a smart baby!Tong Yuan secretly praised in his heart.

Bamboo is the heaviest texture.It is extremely tough and difficult to cut horizontally, but it is extremely easy to cut longitudinally along the grain.This is the meaning of the idiom "the momentum is like a broken bamboo".

But the yellow bamboo is several feet long, it is impossible to stand it upright and then break it down from top to bottom.Ordinary people encounter this kind of situation, most of them rely on two hands to pull, and slowly push it away bit by bit.But that is not only laborious, but also time-consuming.

But for Liu Zhang who came from later generations, this is nothing more than simple application of geometry and physics knowledge.But when it fell into Tong Yuan's eyes 2000 years ago, he immediately felt a sense of shock.

There was a strange color in his eyes.

This son has a persevering mind, knows how to use people well, and is also very clever, and he has taught them carefully by himself... >

Thinking back to the day when I first met, I had the words of the world in my heart, could it be... Alas, but I don't know whether what I did this time was right or wrong.

Inside the room, Tong Yuan's face was serious, looking at the little figure outside, all kinds of thoughts rushed to his heart.

Liu Zhang knew nothing about Tong Yuan's thoughts.He put his head down and put the first separated piece of yellow bamboo aside, looked at the remaining half, thought for a while, but didn't move any more.He bent over and dragged it to the back of the house to put it away, then turned around and went back to the front.

Lifting up the piece of yellow bamboo that had been torn apart, and visually inspecting it for a while, it was broken at about five zhang. Then he let out a sigh of relief, stretched his waist, and began to pack everything up.
