At this moment, it has entered the summer, although the dense grass can't burn, but under the dense grass, there is a thick layer of thick dead grass roots left last year, which is flammable, plus the summer weather is dry and dry, and the land of Qinghai is dry and rainless.

The dead grass roots are little by little, and they spread rapidly.

In order to block the pursuit of the Tang army, Fu Yun did not set fire to one place, but sent a number of cavalry, which directly ignited the grassland within a radius of several hundred miles, and kept spreading around, and in the sight of the Tang army, the entire west was red.

On the first day of the fifth month of the eighth year of Zhenguan, this day is destined to go down in history.

During the day, the tengu eats the sun, the day and night are confused, and the yin and yang are reversed; Then the Mo family's fireworks ascended to the sky, reversing yin and yang, and they could see clearly in the dark, and the soldiers fought as usual; Everyone originally thought that this was over, but they didn't expect that just at night, Fu Yun lit a grassland fire, day and night were reversed again, tonight should have been starry, the sky and the earth were dark, but because of the huge fire, the whole sky was like dusk, and the whole camp was clearly visible.

"Old man, today is really an eye-opener." Cheng Yanjin looked at the red sky in the west, thinking back on the experience of this day, he couldn't help but sigh, he had fought all his life, and he had never seen any scene, but today in one day, three day and night reversal is probably the most magical experience in his life.

The other generals also nodded their heads and sighed.

Today's war has simply subverted their previous concept of war, which is really an eye-opener for them, since ancient times, it can be said that there are very few people who can borrow the time of heaven in war, and the most famous is probably the Battle of Chibi.

"Haha! In ancient times, Zhuge Liang borrowed the east wind, and now there is a Mo family to calculate the solar eclipse, and today's battle will definitely become a good story in the future. Li Jing laughed and said.

Morton suddenly said solemnly: "General Li don't want to torture the kid, how dare the kid be compared with Mr. Zhuge in this battle, this battle kid is just moving his mouth, if there is no General Li to command Ruoding, the kid is calculated and accurate, I'm afraid it won't help." ”

Li Jing waved his hand and said: "Zhuge Liang borrowed the east wind to burn the Cao boat, but who can deny Zhou Yu's credit?" ”

"That's it! I have to say that you kid has a beautiful hand. The other generals also sighed, and there was not much jealousy in their words.

Only then did Merton remember that at this time, there was no Romance of the Three Kingdoms, the world had not yet mythologized Zhuge Liang, and Zhou Yu was the main general in the Battle of Chibi, and his exploits naturally could not be erased.

Hou Junji said with a solemn face: "Now Fu Yun has lit the grassland fire, according to the scout report in front, the fire is less than sixty miles away from the battlefield, if it is according to the speed of the fire, it will burn to us in two hours at most." ”

Everyone's hearts sank, if the fire burned here, the army would move to the camp, last year's dry grass root fire was not very powerful, but after the fire, the grass will be burned to death, and at that time, the use of hundreds of thousands of war horses alone will be enough to drag down the Tang army.

Cheng Yanjin looked at the wounded barracks with a worried face, shook his head and said: "I can naturally retreat, the wounded barracks can't retreat, if the fire burns here, I'm afraid it will ......."

Cheng Yanjin's words were not finished, but everyone could understand what he meant, these nearly 10,000 wounded soldiers, their injuries were finally stable, if they moved, I am afraid that the old injuries would definitely recur, and they would definitely suffer heavy losses at that time.

"If you don't move, you can't do it! Once the fire reaches here, I am afraid that there will be more casualties. Hou Junji frowned.

"Fu Yun's old thief's poisonous strategy." Cheng bit Jin's hateful punch in the air.

Fu Yun did not hesitate to burn the grassland in this fire, the main purpose was to prevent the Tang army from pursuing, but it hit the biggest weakness of the Tang army, the wounded battalion that could not move.

"So far, only the strong man has broken his wrist." Cheng gritted his teeth and said.

The other generals couldn't help but look heavy, they didn't expect that with the help of the doctor, they finally ushered in the hope of life for these wounded soldiers, but how cruel God was, and in the blink of an eye, the hope of these wounded soldiers was taken away.

Once a grassland fire breaks out, unless it burns into the desert or is blocked by a river, I am afraid that it will continue to burn, and unless God appreciates the face, the next heavy rain may be able to extinguish the grassland fire.

But everyone looked up at the starry sky, where there would be the slightest sign of rain.

"So far, I'm afraid that's all there is to it?" Li Jing sighed, ready to order the transfer of the wounded barracks.

"General, don't worry, a kid, the wounded barracks don't need to be transferred." Merton suddenly said in a loud voice.

Li Jing was stunned for a moment, looked at it as Merton, and couldn't help but say urgently: "How can the ink sacrifice wine have a fire extinguishing strategy." ”

The generals looked at Merton with hopeful eyes, you must know that everyone else has already scoffed, but it is the Mo family who has repeatedly created miracles, and even the tengu eclipse day can accurately calculate, maybe there will be a strange plan to extinguish the fire.

However, to everyone's disappointment, Merton shook his head and said: "Shang Shu said: "If the fire burns in the original, it cannot be extinguished. Prairie fires, once burned, are simply impossible to extinguish. ”

Cheng Yanjin frowned and said, "Since it is impossible to extinguish, wouldn't the wounded barracks stay here and wait for death?" ”

The generals also looked at Merton with suspicious eyes, only to see Merton smile confidently: "Regarding fuel consumption, the Mo family also has a lot of research, if the fire wants to burn, it must meet two conditions, one is the oxygen in the air proposed by the Mo family, of course, this is impossible to achieve, and the other is to have combustibles, that is, the dry grass roots under our feet." ”

Li Jing said thoughtfully: "The method of ink sacrifice wine is on the roots of this dry grass. ”

Merton nodded and said, "Yes, since the fire must have dry grass roots for it to burn, but what if there are no dead grass roots around the wounded barracks?" Naturally, the fire couldn't burn. ”

"But how do you get rid of these dead roots?"

Merton still wanted to sell a pass, but suddenly when he looked up, he saw that the generals were looking at him with unkind eyes, and Merton hurriedly said: "I can burn the dry grass roots around the wounded barracks before the fire comes." In this way, the fire spread here, and the dead grass roots here have been burned in advance, so naturally they can't burn up, and the wounded barracks naturally don't need to be moved. ”

"We burn it ourselves? Isn't that self-defeating? Cheng Yanjin looked at Merton incredulously.

Merton explained: "According to the research of the Mo family, only 20% of the people who were actually burned to death in the fire were killed by the fire, and 80% were choked to death by the smoke. If we can dig a circular trench around the wounded barracks as a firebreak, first take the initiative to ignite the fire in the west of the trench, control the direction of the fire, let it dock with the grassland fire, and then ignite the grassland in the north, south and east in turn, so that the burned grassland just forms a large firebreak, and the wounded barracks in the middle are naturally unhindered, and will not be choked by the smoke, so naturally there is no need to move. ”
