"Listening to this, this fire is actually a success."

But at this time, Cen Yin thought about what he had just heard and replied.

"Yes, Lord Shizi, the fire was not broken in the middle, it burned very successfully, and it was not detected by the Beirong people in advance. The ambush of the Beirong army was basically burned. The man in black replied affirmatively.

"What's next?" Cen Yin asked again.

"Because the fire was going up so fast, the fire was too big. Nearly half of the Beijung people who were ambushed in the forest were killed or wounded. The northern road in the forest near Luzhou was surrounded by fire, and they did not dare to go north when they fled. The remaining half of the people all went down the mountain road between the Yuling Mountains, but at this time, they encountered reinforcements from the Great Chu in the west. The Beirong army could not be ambushed, and after meeting with the reinforcements, the number was at a disadvantage, and the terrain advantage was gone, so they had to flee and retreat. But he was still chased and beaten for a long time. Fight, at least...... Lose 10,000 enemies.

If it weren't for the fact that there was a Beirong army distributed in the east, and there was no Jinzhou Great Chu Army to respond to the front and rear attacks, the subordinates felt that it would be possible for them to be wiped out. ”

The man in black said with some excitement: "Burn 30,000 enemies and destroy 10,000 enemies, Beirong didn't steal chickens and rice this time, but broke a full 40,000 military horses." And I'm a big Chu, but I lost a thousand reinforcements. ”

When Cen Yin heard this, he then asked, "What about the fire in Yuling?" ”

"This ......" The man in black was stunned: "The subordinates think, it should still be burning." This battle was fought two days ago. There is no news about the next fire. ”

"The son of the world does not need to worry." Shi Feiwan spoke at this time: "This fire has burned the part that should be burned, and it can't be extended." ”

"Oh? How do you know if it's late? Cen Yin looked into his arms in surprise.

"There is a mountain spring on the west side of Yuling. There are many rocks next to the spring. Fire does not burn easily when exposed to water. And it is bounded by this mountain spring. Further west, the vegetation is not as lush as in the east. And the tree species have also changed, and they are not flammable. As long as you take precautions over there, you won't be able to burn. To the north and south, there are mountain roads, and the roads are wide and without trees, and it is unlikely that they can burn. ”

Shi Feiwan said affirmatively.

"Vegetation?" Cen Yin grabbed the two words in her words: "Does Wanwan refer to the trees on the mountain?" ”

"Hmm." Shi Feiwan nodded: "In the area of Yuling, it can be easily burned, because there are mostly pine trees with strong oil on the mountain, these are flammable trees, in addition, there are a large number of eucalyptus trees distributed, this tree is extremely flammable, and it is a dry day at this time." Therefore, setting fire to the mountain can be relatively easy to burn successfully, and the fire will spread, and it is not easy to break in the middle.

The Beirong army was going to lay in ambush, and they were in the forest. When a fire broke out in the forest, as long as the fire spread fast enough, there was no water nearby, and the Beirong soldiers who were far away from the mountain road and hid deeper could not escape. ”

"Oh? How do you know these things later? "Cen Yin frowned, do you know what kind of trees have grown in Yuling."

"Naturally, I saw it in books." It's not too late to say.

When Cen Yin heard this, he didn't ask carefully, but just smiled: "That's a late word." After the fire burns the place that should be burned, the west, north, and south will not spread, but what about the east of Yuling? The mountains to the east seem to be the same as those in the Yuling area, and there is no water. ”

"The wind is blowing to the west, and the fire will not spread to the east." It's not too late to say.

"What if?"

"This ...... Then I don't know. "It's not too late.

But she knew it in her heart. In order to prevent fire from spreading to the east, in fact, Da Chu sent people in advance to cut down clean trees under a mountain east of Yuling, and had already made defensive preparations. The wind is blowing in the west, and the east is taking precautions in advance. The fire, on the east side, is controllable and preventable.

Of course, these things are not too late to know, and you can't tell Cen Yin so much. Otherwise, as soon as he heard it, he would know that she was a person who knew the inside information.

"Oh? That night, you may guess how the Jinzhou Army set fire to Nayuling, but it was not discovered by the Beirong people. Cen Yin continued.

"Hmm...... Let me guess. If you use wine, you can't. ”

Cen Yin nodded, "The smell of wine is too big, and it is easy for them to find out." ”

"You can use oil. But pouring a lot of oil on the ground is not possible. They will also be easy to spot as they pass by. Shi Fei said: "However, if it is a non-flammable mountain, burning the mountain requires a lot of artificial oil. Can...... The mountain was originally extremely flammable, but there was no need to deal with it on a large scale. A shallow burial of the oil in the soil near the roots of the tree is sufficient. At the same time, if white phosphorus is buried or sprinkled again......"

"White phosphorus?" Cen Yin proposed two words.

"It's what's in the flint here. The flint can be ignited when rubbed because the phosphorus inside is exposed. At a slightly higher temperature, it will spontaneously combust. Some alchemists in the Great Chu rivers and lakes, many of them have more refined things. In many aristocratic tombs, it is also possible to make long lanterns. Some people see ghost fires in the mountains, but in fact, it is caused by spontaneous combustion of white phosphorus. I think that if you want not to be discovered by the Beirong people, after a small amount of oil, you can also mix it with flint and purer white phosphorus powder. However, white phosphorus is too flammable. Therefore, the time of sprinkling white phosphorus must be estimated well, and the part must be treated with some special treatment. For example, adding water to the box.

Also, you have to use a flammable wooden box with water in it. White phosphorus can be preserved in water and is insoluble in water. In this way, when the mountain catches fire, the water inside is poured out or evaporated, and the white phosphorus inside is instantly ignited. The weather is so dry, and there are a lot of eucalyptus and pine trees in Yuling, so put these things at the root of the tree......"

Shi Feiwan raised his head: "I think, it is completely possible that the fire can be raised so quickly, Beirong can't escape, and he didn't find it in advance." ”

Shi Feiwan finished speaking, but he felt that Cen Yin was looking at him. But he didn't throw out another sentence of "how can I know so much about Wanwan".

It's not too late, no matter how much she knows, Cen is no longer surprised. After thinking about it at this time, he just said: "Maybe, what they use is really this method." Even if it is such a flammable forest, it is only poured with oil and treated in a more concealed way, and it is likely to be burned successfully. ”

Shi Feiwan nodded, "Yes." But this method is too particular about the right time and place. It is difficult to change the weather, change the season, change the forest, change the terrain. It's a method that can't be replicated, and it can't be reused. is the Beirong people, who suffered this loss, and will not be so careless next time. They didn't find out earlier this time, and it was mostly because they didn't have the vigilance in this area at all, and they didn't even think that someone would ambush them. ”

"Wanwan is right." Cen Yin was suddenly in a very good mood: "In short, this is a great thing for my Da Chu." Hu Yanjiong must be angry. ”

Then he waved his hand at the others, "Stand down." ”

"Yes."

As soon as the secret guards retreated, Cen Yin began to open the food box that he had brought over from the evening. But he still held her and didn't let her go down. Shi Feiwan really felt that it was not appropriate, so he got up and pushed Cen Yin away and sat aside, and said, "Shizi taste." ”

Cen Yin's hand opening the box paused slightly.

"What's wrong?" It's not too late to be suspicious.

"Late and late fry?" Cen Yin asked. If anyone looked closely, they would notice that his long fingers trembled slightly.

"Hmm." Shi Fei nodded his head.

The corners of Cen Yin's lips suddenly hooked a smile, and said: "Ye never knew that there would be a virtuous time later." ”

After that, the food box has been opened.

After taking out the contents one by one, Cen Yin realized that the preparation was quite sumptuous, four dishes and one soup, although it didn't look as fancy and exquisite as the imperial chef's, but it was extremely good to eat.

"It's good, it's not bad." Cen Yin couldn't help but laugh again. As he spoke, he picked up a small bowl and took advantage of the soup. After taking a bowl, I took a sip of it myself. Only then did he pick up another bowl and give it to Shi Feiwan.

"Why don't you ask if you want to drink it in the evening?" Cen Yin handed the bowl to Shi Fei and asked with a smile. He actually wanted to feed her, but seeing that she had already picked up the spoon with her left hand, he knew that she wanted to eat it herself.

"I've tasted it myself, and it's delicious." It's not too late to say.

"......" Cen Yin was speechless, "That's Wanwan's own thoughts, don't you need to ask me?" ”

Shi Feiwan swept his eyes sideways, and saw Cen Yin burying his head while talking, and poured a big bowl of soup in a few sips, and said, "Look at it like this, anyway, the prince shouldn't feel unpalatable." ”

But when he said that, he added another sentence later: "What does the prince think?" Is it tasty? ”

"There's no need to ask. You won't believe what you said. As a result, Cen Yin replied.

"......" is not late when the top of the head is circled, "It's not delicious?" ”

Cen Yin drank the remaining half bowl of soup in a few sips at this time. Then I took a big bowl of rice and began to pick up a few other stir-fried dishes. Only then did he reply: "It's a little better than the best imperial chef in the palace." ”

"......" Shi Feifei rolled his eyes in his heart.

Cen Yin smiled: "Ye just said, you don't have to ask later, you won't believe what Ye said." ”

"Rhetoric." It's not too late. She wouldn't believe it.

"Ye is sincere." Cen Yin said again.

"Uh-huh." Shi Fei nodded his head. If it's so fake, she believes it's weird.

Cen Yin smiled and said nothing.

He knows that it's not too late. It's no wonder that this kind of remark can make her believe it.

Even though...... Fang Cai's words, in fact, are really his sincere words!

"What's the frying at night?" After tasting a few other dishes, Cen Yin asked.

"The soup is mushroom and tofu soup. This is a bumper harvest in the Northeast, this is the three freshnesses of the earth, this is the pot wrapped meat, and this is the hot and sour cabbage. "It's not too late.

"It's not like Gangnam taste." Cen Yin nodded and replied. Shi Fei is a native of Lingzhou, and he is from Jiangnan.

"Mmmm, I fried it casually, and it doesn't taste anywhere." Shi Feiwan said, and said, "When is the prince going to leave?" ”

"When we have a good night's rest, let's go. It's been delayed for too long, I'm afraid of trouble in the west,"

"Shall we?"

"Mmmm, I'll go to the west with my grandfather sooner or later. There is no need to be afraid of the affairs of Beijing. At this juncture, the person who the master has to keep is the emperor, and he doesn't dare to rob him without giving face. ”

It's not too late to hear it, and it's clear: now is the time...... In the west, Cen Yin still holds up half of the sky. The Qingwang Mansion held heavy military power, and during the war, the imperial court was worried that it was too late for the outside world. The emperor needs Cen Yin too much!
