However, Yang Xianmao found a problem after he was happy, although he mastered this instrument for predicting the weather, but this can only predict the weather conditions in the next three days, but it cannot change the weather, so there is no way to get the south wind he wants through this thing, what he can do now is to quickly measure the weather for another three days to see if there will be a south wind. Pen ~ fun ~ pavilion www.biquge.info

He hoped that before Yelu Hugo arrived with a large army, God would be able to blow the south wind, so that he could use fire to attack and break the Liao army.

This time, he didn't go out of the gate like last time, in that case, the whole city would know, especially let the princess know, it would be troublesome, because this little girl had already threatened that if she got rid of her and went out alone, the princess would run away by herself, and she would go to travel the world by herself, and if she didn't let her take it, it would be troublesome.

Therefore, Yang Xianmao decided to sneak away quietly and come back quietly, with his own ability, this should not be a difficult matter, because he already has a clear understanding of the defense situation of Mozhou City these days.

So, in the evening, Yang Xianmao deliberately called Li Jilong, Cui Yanjin, Guo Shouwen and other generals to drink. Drunk happily and said drunk. After the banquet was over, he closed the door under the pretext that he wanted to sleep and let people not come in and disturb him.

At night, the blizzard, although smaller, did not stop, which gave him good cover.

Changed into a night suit, took a bundle of long strings prepared in advance, quietly jumped out of the back window, took out the Chiyang donkey, crossed the wall to the outside, and under the cover of the blizzard, rode a small donkey to a relatively hidden city wall.

Then he carried the little donkey up the tower.

Because of the snowstorm and the extremely cold temperature, the defending soldiers will get frostbite on their hands and feet when exposed to the cold for a long time, so Cui Yanjin asked the soldiers defending the city except for the observation post to enter the tower to warm themselves and send patrols to patrol the tower.

Yang Xianmao knew about the patrol, so he easily avoided the patrolling Song soldiers, carried the Chiyang donkey to the city wall, and used a thin rope to put the little donkey under the city tower first, and then went down to the city wall to the root of the city wall.

Under the cold winter moon, the water of the moat has frozen. He rode on a donkey, under the cover of a blizzard, evaded the sight of the soldiers on the lookout, crossed the moat, and then, riding the donkey and whipping it, he galloped forward with speed.

The subsequent work was not much different from the first night, the only difference was that there was a snowstorm this night, which increased the difficulty, but the Chiyang Donkey was almost unaffected by the blizzard, and it still arrived at the location designated by Yang Xianmao very quickly. What caused trouble to Yang Xianmao was that under the raging snowstorm, his Kong Ming lantern was easily blown out. Just a moment after the rise, a gust of wind and snow blew, the lights went out, and the new armillary sphere fell.

This is a design flaw, Yang Xianmao thought to himself, after returning to the capital, I have to talk to Zhang Sixun, let him improve it, and see if he can invent a Kong Ming lantern that is not afraid of the wind.

This made him delay a lot of time, but fortunately, when the snowstorm was big and sometimes small, he finally successfully released the Kong Ming lantern and got the data he wanted.

But in this way, time is delayed. So much so that after he had completed four azimuth measurements and obtained data, it was already dawn. And he hurried back with his horse and whip, hoping that the guards and maids would not go in to disturb him, so that he could get back to the room before they found out that he was away.

God seems to be helping Yang Xianmao, when he returned to Mozhou City, the snowstorm suddenly increased, almost a dozen steps apart to see the figure clearly, which of course made Yang Xianmao very happy, he carried a small donkey, hands and feet at the same time, inserted into the frozen rammed earth city wall, climbed the city tower. Then, under the cover of a blizzard, he escaped the patrol and went down to the city.

He rode the donkey back to the yamen quickly, carried the donkey over the wall through the back wall, put the little donkey in the backyard, and then sneaked back to the back window of his bedroom and jumped in.

The door was still closed, and it was evident that the maid had obeyed his orders, and no one dared to come in and disturb him, even though it was already dark.

Yang Xianmao breathed a sigh of relief. He immediately took the new armillary sphere out of his storage bag, read the numbers on it, and compared it to the table.

After checking the manual, his heart suddenly jumped wildly, because it showed that the next day the blizzard would stop, and the south wind would blow and the wind would be weak.

It is recorded in the book that the wind level is divided into three categories: weak, medium and strong, and as for how strong the weak wind is, Yang Xianmao does not know. However, since there was already a south wind, he could not wait any longer, otherwise as soon as Yeluxiugo's army arrived, the Liao army might not be stationed in the woods, and it was likely that the troops would move forward to the city, so that the fighters would be lost.

Yang Xianmao couldn't care about anything else, so he could only use this weak south wind to launch a fire attack.

However, if the wind is weak, if the trees are not dry enough, it is difficult to form a strong fire to burn down the Liao camp.

Yang Xianmao immediately thought of an idea, he wanted to use one night to roast all the trees in the south of Liaoying into dead trees with Chiyang True Fire, so that when the south wind blew, he could use Chiyang True Fire to ignite the trees and quickly form a fire.

Dead wood can easily ignite, and as a result, large areas of trees will be caught in the fire. The more trees you do your own hands and feet, the bigger the fire will be.

According to the data, the blizzard will not stop this night, so that you can cover yourself as close to Liaoying as possible, and roast all the trees in the south of Liaoying and even in Liaoying into dead trees. In this way, the power of the fire attack can be increased to a greater extent. Yang Xianmao waited for it to get dark with excitement.

In the meantime, Princess Xuan'er became angry and took the initiative to come to him and ask him to take her out hunting. Of course Yang Xianmao would not agree, the Liao army was still outside at this time, so it was no joke to have a problem.

After Xuan'er heard the reason for Yang Xianmao's refusal, although she was very unhappy, she also felt that Yang Xianmao was reasonable, and it was not easy to insist, so she pouted and went back to her room.

In the evening, Yang Xianmao put on his night clothes again and went out.

His nightwear is custom-made, with different colors on the front and back, black on the front and white on the back. This way, he can wear the black side when he needs to use the help of night. And when he needs to lurk in the snow, he can wear it backwards, and it becomes white, which becomes a good cover color in the snow.

At this moment, he was dressed in black and left the inner house.

This time, he didn't bring the Chiyang donkey, because his purpose was the woods where the Liao camp was located ten miles away, and the distance was not too far, and his speed was fast enough to get there in a very short time. It is easier to get in and out alone, and it is not easy to be detected by enemy troops.

The blizzard did not abate, and visibility was low, especially at night. So Yang Xianmao crossed the high city wall very smoothly and reached the outside of the city. He blended into the night and the blizzard, and with the direction of the day's memory, he rushed forward quickly.

When he came to the woods, he slowed down, and under the cover of the blizzard, he walked quickly, as close as possible to the Liao camp.

He turned the outer burqa upside down, the white side facing outward, wearing it backwards, wrapped around his body, and lay down in the snow, just like a snowdrift, which could be well hidden in the snow, and even if he moved, it was difficult for others to find it under the cover of the blizzard.

Soon, with his extremely keen ears, he heard the sound of bangs and voices in the woods ahead.

He approached cautiously, the sound of bangs getting clearer and clearer, and he approached slowly with his waist on his waist instead. Finally, he saw a large tent in the wind and snow not far away, and the tent was still lit up. Someone inside was talking loudly, and it was not clear what was being said. But as soon as I heard it, I knew that it was Khitan, so there was no doubt that it was a Liao army camp.

Yang Xianmao walked along the southern edge of the Liao camp, trying to find out how wide the Liao camp was, so that he could decide where to start the fire.

The blizzard served as a good cover for him, relying on his keen hearing, he could hear the slight sound of speech in the tent of the Liao camp, but the other party could not perceive his presence.

As he moved forward along the edge of the Liao army barracks, at the same time, every time he touched a tree in his palm, he quickly wrapped the bark of the tree with the Xuanyin True Fire, and then injected it with the Chiyang True Fire, completely drying the inside of the tree, becoming a dead tree that looked unchanged on the outside, but had withered inside, and when it was just waiting for the fire, it would turn into a raging torch.

He walked along the southern edge of the Liao camp, and everywhere he passed, he used the red sun fire to dry all the inside of the tree.

The blizzard also seemed to be very face-saving, becoming more tyrannical, the wind was howling, the soldiers of the Liao army camp were hiding in their tents to avoid the wind and snow, Yang Xianmao took advantage of the cover of the night and the blizzard, and dared to sneak into the camp of the Liao army.

He did not approach the tent, but touched each tree, roasted the large tree, and then quickly moved to another tree. Covered by a white nightcoat, he took advantage of the terrain to move slowly, from tree to tree, and even if the Liao army patrol walked not far away, she could not be spotted.

It took most of the night for Yang Xianmao to dry most of the trees in the entire Liao army barracks, and then quietly evacuated the Liao camp.

By this time, it was already dawn.

On the way back to Yang Xianmao, the snowstorm had gradually decreased. By the light of the night, he went over the wall and into the city.

When he returned to the yamen, the east side was already white.

Yang Xianmao sneaked into the back garden, and then along the back garden to the back window. He was about to jump out of the window, but he heard someone in the house talking, the voice of a maid who was waiting for him.

So, he opened the window, deliberately stretched and said, "Yo, you guys are so early, I was afraid of waking you up just now, so I went out through the window and walked in the back garden." ”

With that, jump into the window. The two maids glanced at each other, and hurriedly stepped forward and said, "Sir, Princess Xuan'er came here before, asked if you were there, and said that she was going to ask you to build a snowman." As a result, we came in to see that the lord was not in the house, and told the princess, who did not say a word, turned around and left. We were discussing where to report this to the Lord, but it happened that the Lord came back, what do you think?"

Yang Xianmao smiled and said, "It's okay, the child's temper." When it gets warmer at noon, I'll just call her. ”
