The next morning, when the sky became brighter, the full picture of the Julu Army's busy work last night could finally be seen.

The important trenches that lie in front of the vehicle array have generally expanded to more than half a foot. According to the accumulated experience of the Julu Army, the soil produced by the excavation operations was built into a slope on the outside of the trench, and the slope was also filled with nearly half of the people.

Taller.

Standing on the slope, no matter how far you look, you will see a large open space in front of you. The burning of firewood last night left black ash all over the ground. When the wind blows, black smoke rises up.

At this moment, Li Mengxi felt that the black ash blown by the wind was very powerful, and perhaps he could use it to fight.

As soon as I thought about this idea, I suddenly realized that it was feasible. If we collect all the black ash, let the sergeants stand on a high place, and throw it into the wind, the enemy will see the black air billowing in our formation, which will greatly increase our momentum.

Furthermore, black ash, that is, plant ash, seems to be useful in defending the city. When defending the city, a basket of black ash fell from the top of the city, which confused the eyes of many enemy soldiers.

In addition, plant ash seems to be useful for cleaning. If plant ash is sprinkled in the dung pile, flies will not regenerate, so it is feasible to dispose of the corpse. Plant ash can also be used as a desiccant. Suppose there is a sudden heavy rain during the march, and the ground is muddy, and there is no flat ground.

Gather all the army's vegetation and spread ashes thickly in one place, and you should be able to get a few feet of dry ground. With this dry land, you can set up a large tent for the Chinese army, store important supplies, place a camp for wounded troops, etc.

Therefore, the plant ashes should not be just allowed to be blown away by the wind. Li Mengxi thought as he looked at the messy plant ashes blown away by the wind.

Li Mengxi took out a pen and paper, swiped a few times, and wrote down everything he had just thought. Then he turned around and went to the cook camp, ready to find some delicious food.

——

When he first arrived at the cook camp, Li Mengxi heard some quarrels. One of the men complained that the firewood distributed was too little and wanted to order more. The sergeant in charge of dividing firewood said that there was an order from above to use less firewood these days. Li Mengxi heard this.

I understand the reason. It was not that 80% of the army's firewood was consumed in one fell swoop last night, causing a sudden shortage of firewood, so we must economize.

There is nothing wrong with this.

When Li Mengxi was about to leave, he heard the cook muttering, "I have been cooking balls all night in the dark night, but now I have enough food. There is also firewood in the balls!"

Li Mengxi stopped for a moment. He looked back and saw that the person who complained just now was a bearded cook.

Realizing that Li Mengxi was looking at him, the cook suddenly felt guilty. While lighting the fire, he carefully glanced sideways at Li Mengxi, wondering if he had made the military advisor unhappy by complaining just now.

How could Mr. Li be a villain? How could he blame others for such a trivial matter?

——

Li Mengxi walked in front, and a soldier came over on the back. The soldier brought a military ticket and gave it to the cook, saying that he was rewarded by the military advisor for his meritorious advice just now.

The confused cook looked at the ten-pound military coupons in his hand, and then at the soldiers in front of him. He was confused. What suggestions could he make?

"What did I say?" The cook looked confused.

After spending a long time, the cook finally figured out the cause and effect of the matter, and said that he cooked rice while burning firewood last night. That was all, and he was rewarded for it.

Unexpected surprises always make people happy. The cook happily told this interesting story to the people next to him. Someone next to him regretted that he didn't return it last night. A lot of people said that if you keep burning like this all night, how much firewood will be consumed? You might as well make something.

What, if I had known that I would be rewarded if I said one sentence, why not say it?

The unknown cook's casual complaint was worthy of a small military merit. The inspiration he brought to Li Mengxi was that [the use of materials has not been used].

Even Li Mengxi, who could discover the effects of something as small as the ashes after burning firewood, failed to calculate that when firewood is burning, the burning flame is also an important resource.

According to the current combat system of the Julu Army, flames can be used for logistical production, such as burning small clay pots for fire attacks, burning lime for warfare and epidemic prevention, and even throwing soil into the fire and burning it.

You can get a lot of cooked soil for paving the ground. Of course, you can also take the opportunity to process food.

Last night, in order to frighten the enemy, 80% of the firewood in the army was consumed in one fell swoop. If this 80% of the firewood can be fully utilized, thousands of clay pots, thousands of kilograms or even more lime, and enough mature soil to pave a battlefield, and enough to completely

The army had to eat dry food for four or five days. Unfortunately, we had not expected this beforehand, and now there is nothing but black dust on the ground.

Fortunately, a new military order has been issued. There is an order from above to sweep up all the black dust on the ground and put it away. It may be used in future battles.

I had been busy all night last night and hadn't rested long before I was asked to work again. I was asked to sweep dust. Many people felt that this was just torturing people and complained again and again.

The best place for food in the army is the wounded barracks. Li Mengxi served a bowl of broth in the wounded barracks and ate it with pancakes. Liu Bei was beside him. The two of them were eating while discussing a very eccentric issue.

It is still a matter of using firewood. When firewood is burning, it is easy to use. But one day, the enemy enters the valley. "Someone wants to use firewood to roll down the mountain. Throw the torch and block both ends, and wipe out all the enemies in the valley in one fell swoop."

"It's just," Li Mengxi looked up at Liu Bei, "from now on, fire will no longer be of any use to destroy the enemy. Seriously, will it have no other use?"

This problem is very strange. Standing on the top of the mountain, how to use the fire in the valley.

With Liu Bei's unimaginative thinking, he could only think of throwing the damaged weapons and firewood into the valley. When the fire started, the weapons melted into a ball of mixed iron. After the fire died, he went down to pick out the iron. Wouldn't this save money?

Reduce the cost of smelting.

Li Mengxi opened his mouth and was speechless. This is wrong. The melting point of iron is too high. Even with well-sealed soil or with bellows blowing, it is difficult to melt the iron. A huge valley is exposed to wind everywhere.

If there is a pile of firewood, how high can the temperature be? Throwing iron directly into it will be of no use.

Iron definitely won't work, it's not warm enough.

This reminded Li Mengxi that since the fire in the valley was not hot enough to smelt iron, so it was useless to throw iron in, wouldn't it be useful to find something with a low melting point and throw it in?

Li Mengxi thought of low-temperature things, meat.

Suppose that when the enemy is being burned in the valley, the pigs, dogs, sheep and cattle are thrown directly into the fire from the top of the mountain. After a fire, the enemies in the valley are cooked, and the pigs, dogs, sheep and cattle are also cooked...

There is also a possibility that it is burnt.

There is also a possibility that when the fire is halfway burning, it rains, the fire is extinguished, and the enemy is trapped in the valley. At this time, the enemy in the valley should have no resistance, but because of the pigs and sheep dropped from the mountain,

, on the contrary, the enemy army received an unexpected supply, which was a waste of money.

As smart as Li Mengxi, he can think of a solution. He is afraid that the pigs and sheep will be burnt. It is very simple. It is difficult to control the fire in the valley, but it is easy to control the pigs and sheep. Use a long rope to hang the pigs and sheep in the air, no matter how big the fire is.

Even if it is small, it can ensure that the pigs and sheep will not be roasted to death. In this method, the pigs and sheep are hung in the air, so there is no problem of setting fire to the enemy if it rains and fails.

After thinking about it, Li Mengxi always felt that hanging a pig on the valley felt so clumsy? Pigs are meat, wouldn't this in turn increase the courage of the enemy? Especially if the opponent is the Yellow Turbans

Planting an army that is dying of hunger and letting them see meat will make the Yellow Turbans go crazy. The gains outweigh the losses.

Now that he thought about the problem that would help boost the enemy's morale, Li Mengxi then thought that with the help of flames, there could be a better way to destroy the enemy's morale.

Either use a rope or something to hang up to the valley. You can weave a giant tiger out of straw and hang it up into the valley to ensure that the enemy's horses tremble with fear. You can also ask craftsmen to make all kinds of miraculous and terrifying models.

Lighting a fire and hanging at the mouth of the valley, the enemy soldiers saw a ferocious and terrifying figure burning in flames like a god hanging in the air. This was an unimaginable blow to morale.

When the train of thought extends to this point, many ideas come to mind. When it comes to horror and horror atmosphere, it is estimated that no one in this world can compare to Mr. Li. He comes from an era of developed information and has been exposed to various horror movies.

There are countless games, comics, and the like. Just from the scene of the valley, Li Mengxi could instantly think of several extremely terrifying scenes. In such foggy weather, a group of people were walking in the valley. Suddenly they looked up and found something above their heads.

When I took a closer look at the thing, it turned out to be corpses hanging silently in the air, ah...

What's even more terrifying is that what's hanging is not a corpse, but scattered limbs. What's even more terrifying, what's hanging on the limbs is not an ordinary rope, but a vine. When you see this, it adds to the mystery.

The scary atmosphere is even scarier.

If you add some weird elements and stuff some dead snakes into the corpse, just imagine that a group of people are looking up at the corpse in horror, and suddenly a bunch of colorful snakes are thrown out from the corpse's broken belly. This will probably scare them silly.

A bunch of people.

While eating, Li Mengxi started talking about the corpse more and more vigorously, becoming more and more disgusting and terrifying, and Liu Bei frowned.

At the end of the breakfast, Li Mengxi and Liu Bei discussed the best way to use the fire in the valley - smoke and poison.

Smoke means that smoke can be a bluff. What does it mean? If there is not enough firewood, the fire will not be large enough. If the fire is not large, it will not be a deterrent. At this time, you can fire in front and smoke in the back, and use dry fire in front.

If you throw wet firewood behind, a fire will start in front and smoke will start behind you. In this way, the enemy will see the fire and the billowing smoke behind the fire, making it difficult to see the details. The unknown will appear scary. In this way, it will be difficult for the enemy to have the courage to rush in.

In thick smoke.
