ps: I have something going on in the next two days, so I can¡¯t update. Please forgive me. ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª When digging a hole underground, there will inevitably be noise. If you want to know its location, you don¡¯t need modern sonar equipment. You only need to dig a hole and put an empty jar in it. You can hear it. This is the wisdom of the ancients. "Zhang said, I will prepare strong fire oil. As soon as your men come out, I will pour it into the hole, light a fire, and burn you to death." A sinister smile flashed across Yusuf's face. He was very unhappy after losing the competition with Yang Sixu. He finally had the opportunity to deal with the Tang army, so he was naturally happy. As soon as the order was passed, the Arab Imperial Army dug a lot of pits in the city, buried them in jars, and sent people to guard them. There are people from all directions, and you can definitely hear the movements of the Tang army. Especially the empty tank in the north of the city quickly heard the noise. "Well, it's in the north of the city, very good." Yusuf gave an order, and the Arab Imperial Army focused on defending the north of the city, waiting for the Tang army to come and die. However, what Yusuf didn't expect was that he was ranked first, second and third, but he didn't see the Tang army coming out. He was a little confused: "Aren't the Chinese going to make a sneak attack? But if it weren't for a sneak attack, the Chinese would have dug holes in the ground. What's the use?" Yusuf thought about it, but he couldn't figure out what Zhang meant by this move. Time passed day by day, and soon it was half a month, and Tang Jun finally dug the hole. Zhang said that he led his generals into the cave and took a closer look. They saw that the caves were densely packed, like a spider web. Moreover, these caves are very wide, enough for cattle and sheep to pass through. "Very good." Zhang said and nodded approvingly. "Commander, what are you doing digging these holes?" a general asked hurriedly. Many people have asked this question, but Zhang Shuo has not said it clearly, and this time is no exception. The generals are eager to find out the answer from Zhang Shuo's mouth. "Bring in the fierce fire oil and pour it into the hole. Be sure to pour more." Zhang said and ordered loudly. "Commander, if you pour the fire oil on the ground, won't it soak into the soil? What's the use of it?" Chen Xuanli reminded him hurriedly. "It's of great use." Zhang said his answer was convoluted, enough to confuse a knowledgeable person. The generals knew that Zhang Shuo would not say it clearly, so they had no choice but to bury this question in their hearts. As soon as the order was passed, the soldiers of the Tang Army moved in, brought in the burning oil, and poured it on the ground. According to Zhang's request, the entire cave collapsed and the cave was greasy. "Drive the cattle and sheep in and pack them full." Zhang said and ordered. "Commander, why are you driving the cattle and sheep in?" A general asked in confusion. This question was exactly what the generals were thinking. However, Zhang Shuo had no answer as always. The Tang army drove the cattle and sheep into the caves and stuffed them full. "Light the fire." Zhang said and gave the order. Tang Jun lit a fire, and all the entrances were doused with fire oil, which was easily ignited. I saw countless fire heads drilling into the ground. After a while, the mournful sounds of cattle and sheep could be heard in the cave, as well as the smell of burning. "This" The generals smelled the strong smell of burning and looked confused. Zhang talked about using fire to attack and burn down the city walls, but if he lit the fire in the cave, what would be the use? Chen Xuanli and Yang Sixu looked at each other, if they had some understanding, they nodded in unison and praised loudly: "Wonderful! Wonderful! This is a wonderful plan!" Zhang said he nodded appreciatively and said, "You finally thought of it. Not bad." "Don't dare to take it seriously. "Compared with the commander, we are far behind." Chen Xuanli shook his head with emotion and said: "We didn't figure it out for ten and a half months, and we didn't realize it until we lit the fire. " "What do you think?" What?" Xue Zhi asked in confusion. Zhang Shuo, Chen Xuanli, and Yang Sixu looked at each other, laughed loudly, and did not explain to Xue Zhi. The Arab Empire soldiers on top of the city were patrolling, and groups passed by. It didn't take long for the soldiers of the Arab Empire in the north of the city to notice something strange. They were all sweating profusely and complained loudly: "The weather is really hot, how can it be so hot?" "Hot? It's May, how can it not be hot?" " But it can¡¯t be that hot, right?¡± ¡°It¡¯s so hot all of a sudden. It¡¯s unbearable. I¡¯m sweating all over, and I¡¯m breathing hot.¡± It was like being in a furnace. It was uncomfortably hot. Not only was I sweating all over my body, even my breath was boiling hot. "No, no. It's getting hotter and hotter. Although it was hot just now, it was bearable, but now it's unbearable." "This has nothing to do with the station."Like on a fire. " "My feet feel as if they are stepping on coals of fire. " "foot? No, the ground is hot. " "Yeah, the ground is getting hotter and hotter, like a red-hot iron. " It didn't take long for these soldiers patrolling the north of the city to find that the ground was getting hotter and hotter, like a red-hot iron. " What happened? How could the ground be so hot? " "I really can't stand anymore, retreat, retreat. " "But we have to patrol. If we retreat, you will not let us go. " "No. It's really hot here. If you stay here again, you'll be burned to death. ¡± The soldiers of the Arab Empire left the city and retreated to a distance while talking about it. Unfortunately, they did not stay far away for long. After a while, the place where they stood was also hot, and they had to retreat again. Just like that, They retreated again and again, no matter how many times they retreated, retreating farther and farther away. ¡°Look, why is the city head red? " "real? Why are the city walls red? Like red-hot bricks. "After a while, the Arab Empire soldiers discovered that the northern city wall was red, like burning bricks. "Something's wrong! Go and report to your lord quickly. "The soldiers here finally realized that something was wrong, and hurriedly sent someone to report to Yusuf. Yusuf was discussing the military situation with the generals. They guessed and guessed, but they couldn't guess what Zhang said about digging holes. It was said to be a sneak attack. , After digging for so long, there was no movement. If it was not for a sneak attack, then what was the reason for digging the hole? During the discussion, the guard came in and reported: "My lord, the wall in the north of the city has turned red, like bricks being fired. of. " "impossible! "There was a roar, and all the generals rejected it in unison. "You didn't lie? "Muhammad asked hurriedly. "Sir, who would dare to lie about such a big event? Whether it is true or false, you can tell at a glance. "The guard hurriedly reminded me. "This makes sense. If you want to lie about military information, you must also find a decent reason that is not easy to be exposed. The wall in the north of the city turned red, like fired bricks. This requires It¡¯s too easy to find out, just go and take a look. If there is no such thing, who dares to make an argument? ¡°Let¡¯s go! Go and have a look. "Yusuf's eyes flashed, he stood up suddenly and strode away. The generals followed behind him and followed quickly. The group of people hurried towards the north of the city. From a distance, they saw the wall in the north of the city was red, as if it was being Like fired bricks, everyone was dumbfounded: ¡°How did this happen? How did the city wall become like this? It's possible. " "Is it God's punishment? "The city wall became like red-hot bricks. This thing was really unexpected. The generals started shouting, but they didn't understand why. They didn't understand why the city wall suddenly became like this. Except for the great They really couldn't think of any other explanation for God's divine punishment. A wave of scalding heat hit their faces, making them feel suffocated. Yusuf stared at the red city wall with his eyes shining brightly. He raised his eyebrows, changed his mind, and immediately figured it out, yelling: "Zhang said! Well done you scheming Zhang! " "Sir, what does this have to do with Zhang Shuo? "Some generals didn't understand. The city wall turned red, like bricks being fired. This had something to do with what Zhang said. "This is what Zhang said was set on fire. "Yusuf's eyes were full of hatred. "My lord, can't you? set fire? How could we not discover fire? "The generals looked around for a long time, but there was no spark. How could they set a fire? "He put the fire underground, how could you see it? "Yusuf was Yusuf, and he quickly figured it out and said: "He dug the hole not for a sneak attack, but to set fire to the city wall. "These words are so unbelievable, far beyond normal people's thinking, that the generals were directly petrified. Even Muhammad, who has always been resourceful, is also puzzled, with a look of confusion on his face. "Bricks are fired in the furnace. Zhang said that by digging a hole in the ground, he wanted to make a brick oven in the ground in this area. He only needed to set a fire and the wall in the north of the city would be made of bricks. "Yusuf explained. "It's okay if he didn't explain. As soon as he explained, questions came. "My lord, is this impossible?" To make bricks, you need a lot of firewood. Where do the Chinese get the firewood? "Some generals thought about the problem of fuel. They have all seen burning bricks, which requires fuel. Even if Zhang said that the wall in the north of the city should be burned as bricks, it would also require a lot of fuel. Where can Zhang find so much fuel? " You use your stupid pigThinking about it, Zhang said that just pouring strong fire oil into the hole and driving the cattle and sheep in would be enough to burn the wall in the north of the city to this point. "Yusuf couldn't wait to slap this talkative general. "Yusuf was right. Zhang said that digging a hole in the ground would turn the entire northern area of ??the city into a brick-burning furnace. Pour strong fire oil in the hole, and that would be For fire, it would be difficult to burn cattle and sheep. Cattle and sheep contain a lot of fat, which is flammable and resistant to burning. "This Chinese people. How treacherous! "The generals who understood were stunned and exclaimed in unison. Zhang said that this move was beyond their expectations and they had to be shocked. "My lord, even so, we don't have to be afraid. The walls were red, we couldn't stand on them, and the Chinese couldn't attack. "There are generals who don't take it to heart. "You are so stupid! How stupid! Yusuf roared loudly at the general and shouted: "This is just the front move Zhang said, his back move will be here immediately." " As if he was commenting on Yusuf's words, as soon as he finished his words, a black mass hit the red city wall, and immediately there was an earth-shattering "bang bang" sound, and a vast white mist "What are the Chinese using?" "The generals looked at the "spectacle" in front of them and asked puzzledly. "Water. "Yusuf's answer was extremely concise. "Water? "The generals were confused. Yusuf's answer was absolutely correct. This is indeed water. Because red-hot stones and bricks will break when exposed to water, which will speed up the destruction of the city wall. As the water continues to be destroyed, As it hit, the city wall was destroyed faster and faster. At first, it was just small pieces, and then it was big pieces. Then, cracks appeared. r1152.
