Shanhaiguan.

The mountains are steep and the woods are shady.

Yun Xiaoshui finally met the border and wall-building officers here, and the military marquis Xiang Tuoxiang in the servant battalion. He handed the two letters and the conscription order to the old soldier to read, and after reading it, the old soldier said with some excitement:

"Hahaha...... Are you Yun Xiaoshui? The righteous son of Lord Shouji of Bohai County, my virtuous nephew? Then this is the female guard Leng Yue! Are you calling? Is it really good at a young age? ”

Yun Xiaoshui nodded solemnly, but he already understood in his heart, "Do you believe in yourself?" ”

Subsequently, Xiang Junhou and Yun Xiaoshui actually stopped talking. This made everyone feel that if it weren't for those two letters, they wouldn't even be able to see Xiang Tuo's face. Without that call-up warrant, a simple reception would not have been possible.

At this time, the beautiful escort who was next to Yun Xiaoshui was dressed in uniform and with a sword, and she was more conscientious and close to Yun Xiaoshui.

Xiang Junhou arranged for a 500 lord surnamed Zhang to open up an exclusive corner for Yun Xiaoshui and Leng Yue in the big tent, and opened a small tent door.

Xiang Junhou also instructed Yun Xiaoshui to guide the construction of the wall when they had a good way, and to go around and play when they were not working, but don't run away, the beasts here are in groups.

In the afternoon, the two of them slept for a while, and suddenly Yun Xiaoshui was awakened by the heart-rending cry outside the tent. The cries of several big men, rough, high-pitched, and deep...... It was the first time that Yun Xiaoshui heard a man's cry more touching and hurtful than a woman's procrastinating singing. When I came out of the camp tent and asked, I found that the city wall collapsed during a thunderstorm a few days ago, killing six people and wounding three people. It's their fellow villagers and clansmen, or good friends crying about them.

Yun Xiaoshui listened to the thunder and lightning of the servants cursing and collapsing the city wall, and his heart couldn't help but feel sad.

Suddenly the sky changed, as soon as the wind blew, it was as dark as ink, lightning and thunder, and not far away, Huo Liangliang's huge extra-long and multi-forked lightning was like a sharp sword piercing the boundless dark sky between the clouds and the earth with an electric field strength of more than 27KV/CM. A rumbling burst of thunder immediately slashed down, and the whole sky exploded, shaking people's ears numb. It's going to be a thunderstorm again!

"Quick! Leng Yue, bring your cloak and hat and go to the city wall! Yun Xiaoshui immediately shouted to Leng Yue.

By the time the two of them left the tent, the clouds were rolling overhead, spreading in all directions, threatening to cover all the alpine forests near and far and the sky.

"What are you doing there? Master! It's going to rain heavily, and it's thunder and flashing, how scary! ”

"Have you forgotten what I did when I unveiled the emperor's list? I have a way to keep the walls from collapsing! ”

A few of the veterans who stayed behind looked at Yun Xiaoshui stupidly and the two of them ran out, and no one stopped them. Because they know that Yun Xiaoshui, the little young master, is not simple, maybe he is really a prodigy.

At that time, people were extremely superstitious, and as long as there were things that their cognitive abilities could not understand, they would attribute them to ghosts and gods.

Yun Xiaoshui and the two of them had just arrived at the area where the wall was built, and they were still dozens of steps away from the city wall, when they heard Xiang Junhou's angry voice shouting: "Why are you here?" Can't help, add to the chaos, go back quickly! ”

It turned out that Xiang Junhou personally participated in covering the newly built section of the wall with straw and reed mats, which was also the most commonly used protection measure.

"Your Excellency! The two sections of the wall on the hill and on the mountainside were in danger of being blown down by lightning because of their high position and the tall trees on either side. Let me help you deter the thunder and lightning and protect the walls! Yun Xiaoshui shouted loudly against the wind that was gradually blowing.

"Nonsense! Can you deter lightning from it? That's all about the gods! ”

"Trust me! There are big wires and big iron cones! ”

"I believe you're a ghost! Get out of here! ”

Yun Xiaoshui didn't listen to him, and immediately began to search in the wall-building tool field, and finally found what he wanted.

Several large iron cones and several iron rings of various sizes, as well as thin wires. Of course, the so-called big iron cone at that time was really big, and the thin iron wire was not an iron bar in the modern sense, not very thin.

Yun Xiaoshui took Leng Yue to pick up the iron cone and wire and ran to the city wall, Xiang Junhou was so angry that he stomped his feet and scolded, if he didn't have manpower, he would not hesitate to order the soldiers, tie up Yun Xiaoshui and the two of them and send them back to the camp tent.

Yun Xiaoshui erected an iron cone with the help of Leng Yue, and then fixed an iron ring to one end of the iron cone with a thin iron wire, and then pulled the thin iron wire and inserted it into the ground. The two of them had just come down from the high wall of the city when there was a boom and a thunderbolt fell on the place where they had just been. I saw that a miracle appeared, the thunder and lightning that rolled down slashed on the iron cone, and it went into the ground along the wire, like a fierce tiger falling to the ground and not moving, what is not a drop!

Seeing with his own eyes the extraordinary effect of Yun Xiaoshui's extraordinary behavior, Xiang Junhou was stunned on the spot for a while.

"Your Excellency! Take advantage of this lightning gap, please quickly send someone to do the same as me, this is called a lightning rod, install it and insert it on the top of the wall, and then pull the thin wire under the wall and insert it on the ground. It is guaranteed to be able to deter the thunder and lightning and keep the city wall from collapsing! Be quick, or it will be too late! ”

Without waiting for Xiang Junhou to answer, Yun Xiaoshui took Leng Yue alone and rushed to the nearest section of the city wall again with a lightning rod that could not be simpler.

At this time, the bean-sized rain crackled and fell again.

When he was about to climb the steps of the city wall, the iron cone that Yun Xiaoshui was carrying was crooked, almost bringing him down. It wasn't that his feet had slipped, nor that his waist had twisted and slanted, but that an invisible force had drawn to the iron cone on his shoulder.

"What's wrong, young master?" Leng Yue asked.

"There's a force that draws me in! Haven't you encountered it? Yun Xiaoshui replied.

"Nope!"

Yun Xiaoshui deliberately stopped and tested a few times with an iron cone, and sure enough, there was another gravitational force coming from the grass.

"Huh? Magnets? ”

Finally, in the grass, Yun Xiaoshui found several large stones that were attractive to iron lying down. After remembering the relative position, their master and servant continued to climb up.

When the ancient Great Wall was built, there was a circular arch on the inside of the wall not far away, and there was a masonry ladder leading to the top of the city wall, which could be used by the soldiers defending the city to get up and down. The outside of the top of the wall is built into a battlement, which is called a pheasant moat in ancient times, and there are lookouts and shooting eyes on it.

Of course, the main purpose of the construction of the city wall was to defend against foreign enemies and strengthen national defense. Five miles and one fort, ten miles and one beacon. The castles are connected and the beacons are facing each other. The beacon tower, which lit smoke during the day and set fire at night, was an independent high platform, on which there were watch houses and equipment for lighting smoke and fire, and under the stage were houses where soldiers lived and sheep and horse pens.

Yun Xiaoshui and Leng Yue installed lightning rods on the city walls on this large section of the mountain, which is the simplest "direct lightning rod" according to modern physics. When the two of them returned, they took two magnets and placed them on the ground in the construction tool yard.

After Yun Xiaoshui and the two of them left, although Xiang Junhou, who reacted, did not believe it very much, but what his good friend Ji Junshou said in the letter that Yun Xiaoshui saved the life of the county guard, eliminated the plague of the county guard, and saved the old lady of the county guard's mansion are all true, these are indeed not ordinary people can do it!

"Could it be that Yun Xiaoshui is really a prodigy, can talk to Lei Gongdian Mother, so that Lei Dian will not come to collapse the city wall?"

Xiang Junhou thought as he ordered a thousand people around him to take people to the mountainside section to install lightning rods.

"Li Qianren, did you see it all just now?"

"What? …… The wire that the little master made? See! ”

"Learned? How to wrap it, how to install it, and where to plug it? ”

"It's going to happen!"

"Then you take someone to load it up! Let the thunder and lightning dodge! ”

"Loading ...... Fart! Good! I'm going to pretend, I'm going to pretend! ”

Li Qianren said that he was pretending, his legs and feet also moved, and he took four soldiers, including a hundred generals, a five hundred masters, and three officers among the five people, carrying iron cones and wires.

However, he was not happy to install any lightning rods in his heart, and thought to himself: "Cut! And let the thunder and lightning dodge! Can this little kid understand a ball? That thunder and lightning are all the things of the gods in the sky, or is it a major event, how can it be that you as a mortal can control it? ”

The hearts of the other four officers and soldiers were similar to Li Qianren's thoughts, they didn't believe in Yun Xiaoshui, and they didn't want to toss around blindly and work in vain.

As soon as they stepped on the steps to climb the wall, the rain began to fall heavily, and the thunder and lightning became much more dense and heavier. The souls of the five people were almost scared away, and they didn't want to go to the wall.

"Throw the cone against the wall! Fast! Let's not install it! Ann what Ann, there will be no fart! When I go back, I will say goodbye, and the caliber must be the same! Who the hell is telling the truth, sir, I screwed off his head as a night pot! ”

"Master of a thousand people! What to do with this wire? A soldier asked.

"Climb up and throw it out of the wall!"

Thunderstorm overnight!

Xiang Junhou and Guo Junhou in the convict camp, both of them had sleepless nights. That Guo Junhou's name is Guo Tie. As the chief cultivators of these two sections of the hundred-mile city wall, the two of them could not help but worry about the safety of each section of the wall.

But if a thunderbolt strikes down and collapses a section of the city wall, it means that it has to be started again, and I don't know how much the construction period will be extended, but the manpower and material resources consumed are huge! Naturally, they all did nothing.

Xiang Junhou couldn't sleep at night, and when he got up, he didn't bring the guards, and walked out of the camp alone. Only a patrol followed.

The "boom" thunder grew louder and louder, and the lightning became more dense and brighter. A series of thunderbolts rolled from the sky, and Xiang Junhou clearly saw that lightning with a maid struck the section of the city wall on the top of the mountain.

This section of the city wall also happened to be connected to a section of the wall built by the convict camp, and I saw that the lightning that split on the wall of the camp "swooped" and drilled into the bottom along the wire inserted in the ground, and the lightning that split on the wall of the convict camp "boomed" and shattered a long section of the city wall.

Tianming saw that a section of the wall on the mountainside on Xiang Junhou's side had collapsed, and the section of the wall on the hill was unharmed. On Guo Junhou's side, the section of the wall connected to the wall of the servant camp collapsed.

"Your Excellency! Are the people you sent doing what I said? Yun Xiaoshui didn't believe that his lightning rod technique could fail, so he went to ask Xiang Junhou.

Xiang Junhou tightened his eyebrows and sent someone to quickly call the five officers and soldiers.
