Xia Yu looked up at the sky, the noon sun was shining warmly on his body, wearing thick cotton clothes, some sweat was oozing from his body, he took a big breath of air, and said to Li Shimin: "Today's weather is so good, the air is so fresh." ”

"Brother Xia, it's all this time, what are you thinking in your heart, you're really going to die." Li Shimin's forehead was worried, and the wrinkles were piled up together.

"Brother Li doesn't know, this burning of grain and grass has to wait for the Li family army and the Sui army to fight, so we can act cheaply. Otherwise, if the Sui army comes to support, we will be in some trouble. It's the personnel aspect. In terms of time, it is best to wait until the middle of the day, and the time is just right. ”

When Luo Yu and the others saw Xia Yu get up, they immediately rushed over and asked about burning grain and grass.

Xia Yu said indifferently: "Wait a little longer." ”

Everyone waited until noon in the midst of the fire, and was about to order Qin Wangjun to attack, Xia Yu said leisurely: "We don't need so many people to burn grain and grass, we only need to dispatch two people." ”

"Two people, General Xia, you're not joking, are you? There were 2,000 Sui troops near the grain and grass stacks, and one spitt was enough to drown us. ”

"I can't believe it, unless you have great magical powers, brother-in-law, are you a god?"

"This matter is absolutely impossible to complete, Xia Yu, don't make trouble."

In response to their doubts, Xia Yu smiled confidently, pointed at Su Xun and said, "You can go with me." ”

The two came to the sunny hill yesterday, and Xia Yu picked a smooth stone and sat down.

Su Xun asked anxiously: "Brother-in-law, aren't we going to burn grain and grass, what are we doing here?" ”

Xia Yu angrily slapped Su Xun on the back of the head: "Who told you that you have to run to the camp of the Sui army to burn grain and grass." ”

Su Xun was surprised: "You mean, standing here can set the grain and grass on fire, what the hell is this?" ”

Xia Yu took off the burden on his back and said to Su Xun: "What do you think this is?" ”

With a bang, a large number of transparent crystal mirrors fell out of the baggage. Some are big, some are small.

Holding a convex lens, Xia Yu placed a piece of withered grass under the mirror, and after less than ten seconds, the withered grass automatically burned.

Su Xun for this

The strange scene widened his eyes: "Brother-in-law, how did you do it?" ”

Xia Yu placed the convex lens vertically in the front, and the concave lens vertically in the back, aiming at the direction of the Sui army's grain and grass.

More than a dozen pairs of such double-sided mirrors were set up one after another, and Xia Yu clapped his hands and said, "We are waiting here, and we will witness a miracle soon." ”

After Xia Yu left, Li Yuan came to Li Shimin's army again, and saw that Qin Wangjun's army did not move at all, so he couldn't help but be extremely dissatisfied with the behavior of his third son.

Li Shimin knew what Li Yuan was thinking, and said embarrassedly: "Xia Yu and Su Xun have already set off, and the two of them have gone to burn grain and grass." ”

"What? Two people go to burn grain and grass, Shimin, are you relieved? Anyway, I'm not at ease. How can you easily let the two of them go, in case something happens, how can I explain it to the Su family. ”

Li Shimin's back was covered in a cold sweat, blaming him for his usual great belief in Xia Yu, Xia Yu said that the two of them would go, and he would let them go.

Li Yuan sighed in his heart, it seems that they will not burn the enemy's grain and grass today no matter what.

Just thinking this, Luo Yu suddenly shouted, "Look, look! ”

Looking at his voice, I saw bursts of green smoke rising from the grain and grass of the Sui army, and in the blink of an eye, the kung fu turned into a raging fire.

Visible to the naked eye, the enemy was in disarray inside the camp.

The fire was extremely ferocious, rising into the sky, and the distance from the grain and grass hoarding place to the moat was three miles away, and the Sui army took wooden barrels to scoop water into the moat.

Yuwen Chengdu supervised the battle above the city, and the frontal battlefield killed you back and forth, agitating.

In the corner of his eye, he saw the grain and grass stack on fire, and was shocked, his original plan was to use the grain and grass to lure the enemy to burn, and there was a garrison next to him to deal with the sudden change.

The battle lasted for half a month, during which as he expected, the enemy came to attack the grain and straw stacks, and they were all captured.

After three or four times without success, he expected that the enemy would no longer have the idea of fighting grain and grass, so today he let the garrison next to the grain and grass withdraw and put it into the frontal battlefield.

After observing the city for a while, Yuwen Chengdu frowned even more, because there was not a single Li Jiajun in the place where the grain and grass caught fire, how did they do it.

Out of the corner of his eye, he caught a glimpse of what appeared to be a blinding spot of light projecting onto his face, and he instinctively closed his eyes.

After his eyesight recovered, he looked in the direction of the light spot and saw two people standing on the hill not far from him, one of whom was Xia Yu.

"Xia Yu!"

Yuwen Chengdu's teeth were about to be crushed, and he punched the battlements, and the green bricks shattered and fell to the ground.

By the time the Sui army came back with the barrel, the fire was too big to be controlled, and nothing could be done.

The Sui army, which had lost food and grass, could only retreat to Huoyi City.

It is true that as Xia Yu said, before the afternoon, he burned the enemy's grain and grass, not only that, but he did not move a single soldier, preserving the strength of the Qin Wangjun.

The generals on Li Jiancheng's side originally wanted to see Li Shimin's jokes, but they were slapped in the face.

Li Yuan was even more relieved, and his face wrinkled into orange peel with a smile like Li Shimin: "As soon as Xia Shi's nephew came this time, he built such a miraculous feat, which is really indispensable." ”

"I just don't know how General Xia burned the grain and grass, no one got close to each other's grain and grass, and he burned it himself, which really opened my eyes, can you tell us about it?"

Xia Yu took out the crystal lens rewarded by the reader and demonstrated it to the generals.

After the demonstration, he casually handed the lenses to Li Yuan: "Uncle Shi, these things will be left to you, maybe they will be of great use in the future." ”

Seeing Xia Yu casually gave away the lenses, Li Jiancheng's generals held them in the palm of his hand as if they had been treasured.

Xia Yu glanced at Li Jiancheng, and it seemed that what the other party promised him should be fulfilled.

Li Jiancheng walked to the middle and said to Li Yuan: "Father, the third brother is just here." Burning grain has done a great job, so it is better to let Qin Wangjun be fully responsible for the supervision and care of grain and grass. ”

Li Yuan nodded, the old man was very relieved, and now he thought that the two brothers had reconciled, and Li Jiancheng took care of Li Shimin everywhere.

After the generals dispersed, Li Jiancheng returned to the military tent and hated the root of his teeth, and he would never let Li Shimin sit big!

Pei Lin knew what Li Jiancheng was thinking, his eyes rolled for a while, and he said to Li Jiancheng: "Second son, if this is not the case, we will take the handwritten order to transfer one or twenty people to the army of King Qin every once in a while on the grounds that there are injuries in the army from time to time. The third prince takes into account the overall situation and will not give it back. ”
