Although he did not directly suspect that Yun Xiaoshui and Meng Zheng would do this, but only this point, Ren Huan also knew that from now on, with Meng Zheng, a young general, here, his self-reliance as the king would be a great cause, and he would not succeed!

Within a few days, there was a rebellion of thousands of people in Guilin County, roaring through the mountains and forests, and robbing homes and houses.

Ren Huan did not pass through the imperial court, and directly ordered Meng Zheng to lead troops to suppress the bandits and quell the rebellion.

"Go! Bring your special combat team! With a very small number of people invested, a great victory was achieved, and Ren Huan was given a dismount! It also makes him understand that the real elite troops are on your side, that is, on the side of the imperial court. Send the special team first, and send it immediately, to collect all aspects of the enemy's intelligence, the more the merrier.

Then arrange the rear, you are not there, the thunder will not move, especially the three passes, and you will not hesitate to oppose anyone at all costs, and never let the passes be lost. ”

"Good! Everything is at the mercy of the craftsman! The end will be very careful! After I left, I will carry out a set of military passwords every day and night, and add two teams to the light and dark posts! ”

Yun Xiaoshui nodded in agreement, and then officially said goodbye to Meng Zheng and left Lingnan, because Yun Xiaoshui received an order from the First Emperor to rush to the Great North. There was an earthquake in the Gubeikou Great Wall section of Miyun County, Youjun, and a mountain crack occurred in the mountain where Gubeikou is located, and the four Great Wall piers were cracked on the outside, and the width of the gaps was more than one foot.

This journey is full of dust, but Yun Xiaoshui is tired. As soon as he arrived at Gubeikou, Yun Xiaoshui went to sleep, and slept through the day and night, not scaring the people around Yun Xiaoshui, but scaring Zhang Liang, the military advisor of General Meng Tian, who came earlier.

Zhang Liang and Yun Xiaoshui are a rare pair of "year-old" friends, seeing that Xiaoyou has been sleeping all the time, Zhang Liang can't sit still and can't stand still. Several times I wanted to go into the camp tent and wake up Yun Xiaoshui, but he was stopped by Bingshuang and Gu Yue, telling him not to worry, Yun Xiaoshui had been like this many times, and he woke up after sleeping enough, and he was about to wake up.

After Yun Xiaoshui woke up, he and Zhang Liang took people to the city wall to take a look, except for the cracks caused by the surface and the collapse of individual lots, they didn't find any bigger problems. In the beginning, the lightning crash was a major killer of the Great Wall, but now lightning is not a problem, and the earthquake has become the number one killer of the Great Wall.

Of course, there are also flood erosion, plant destruction, wind and sand erosion, wind and rain erosion, etc. The Great Wall is basically located in the earthquake zone of our country, how can it avoid being shaken down by the earthquake? Yun Xiaoshui couldn't say these words to Zhang Liang, and he said them in vain.

In view of the cracking of the wall and the collapse of individual wall sections, Yun Xiaoshui designed a double auxiliary wall or a method of piling sand and soil inside to solve the problem.

It is on the wall that is easy to collapse and crack, such as the wall that has collapsed and is repaired again, the method of sticking to the wall inside and outside and narrowing the wall, five steps or ten steps plus a small wall five feet wide and five feet thick, to support the big wall.

Where there is sand on the inside of the wall, the sand pile is used to assist and support the large wall. But it can't be piled up outside the wall, that would be a sandy slope, and it won't play the role of blocking the incoming enemy, and people and horses can rush over from the sandy slope.

"Young Master! There is a crack in the wall that is caused by a small sapling growing from inside, not by an earthquake! What to do? Wind Thunder shouted after spotting it not far away.

Yun Xiaoshui went over to take a look, it was some purple trees, the root system of this tree is particularly developed, and the branches and leaves on it are luxuriant, the branches are messy, the leaves are crazy and the leaves are covered with puffy needles, which are very astringent. There is slime in the book cover, the tree is hard, the bark is strong, and the bark can be braided with ropes.

Yun Xiaoshui found that there were many more in this wall, the small ones were just filled with brick joints, and the big ones cracked the brick walls.

"It's the same as the kind of tree that appears on the grave, which has no effect on cutting down and can only be removed by uprooting. Master! "Brother and sister Gu Yang and Gu Yue both remembered that there was such a tree in their hometown.

Yun Xiaoshui told them that there was no way to uproot this city wall.

"Young Master! So what to do? Everyone else had the same question, even Zhang Liang was looking at Yun Xiaoshui, asking him what to do with his eyes?

Yun Xiaoshui smiled and said, "Peel the bark!" Peel off the bark, be sure to peel it around, peel it clean, so that the tree will dry up and die because it can't absorb water and nutrients! Don't cut down and pull it, it's bound to hurt the wall. If the tree can't be removed, the wall will break! ”

"Huh! Do trees all bark to transport nutrients and water? Is the same with flowers and plants? Master Craftsman, tell me more about it! Zhang Liang's eyes seemed to light up, and asked Yun Xiaoshui.

It seems that the ancients did not have a little bit of these plant knowledge, and Zhang Liang, as a military advisor of a large army, was able to humbly ask for advice!

"Yes! Flowers and trees are transported to the leaves through the bark after absorbing water and nutrients from the root system, and the leaves are then exposed to sunlight for management...... Oh! It is processed, just like the human stomach digests and transports it to the small intestine, and then runs to the whole body to grow. ”

"Huh! Learn! Learn! No wonder people say, 'A man wants face, and a tree wants bark'! I see! ”

Subsequently, a few people were talking and walking, and Yun Xiaoshui saw on both sides of the Great Wall that as long as trees could be planted, that is, where there was soil and not all stones, a small forest belt was planted, and the dense woods would just be able to be sandwiched inside and outside to protect the integrity and longevity of the city wall.

made a plan, found a way, and let the servants start working hard.

Zhang Liang happily said to Yun Xiaoshui: "The general has made another kind of wolf brush, and he is intoxicated with it these days!" Don't you want to check it out? Craftsman's little adult! ”

"If you don't want to call me an adult, you just call me by my name, why do you have to add a 'little' word?" Yun Xiaoshui pretended to be angry and shook his head in a dashing manner, throwing aside the long hair on his forehead.

Zhang Liang raised his hand and patted Yun Xiaoshui's shoulder again, and Yun Xiaoshui retreated diagonally and dodged, making Zhang Liang shoot in the air. Chongyun Xiaoshui smiled and said, "Doesn't your name have a 'small' character?" Isn't it good for me to call my official position and my name? ”

"Okay, you ghost! Walk! Let's see what the general can be happy with? If you faint, you pinch someone, I pinch his thigh, and then wake him up! Hehehe......"

"Hahaha...... That's it! ”

The two of them laughed and walked into General Meng Tian's camp tent to see that Meng Tian was not happy, and was holding a brush in one hand and was stupid there!

There are also words in the mouth: "This rabbit fur and wool are too soft, and they can't be bounced up when pressing, and this wolf hair is too hard, and it is difficult to press down. What to do? What to do? ”

"Oh no! Master Advisor! Our general, a brush idiot, is crazy at this time, and he is babbling! Yun Xiaoshui deliberately opened his eyes wide and said.

Zhang Liang shook his head and didn't speak.

"You're crazy! Prodigy, little craftsman, little adult! Come and see how to help me with this! Meng Tian turned his back to the tent door and didn't look up, but he had already found the two of them, and he also knew that Yun Xiaoshui was coming, and the early warning system in his body was really developed after years of field combat.

"Hey-the general is an expert in making brushes, and the little master can only repair walls, so if you ask him about brushes, how can he do it?"
