There are many people who have this idea with Wang Shichong, and they are all thinking about Hedong and Luoyang, who will fall first, Luoyang will fall, Li Jing will be able to use the fastest speed to mobilize his army to support Hedong, Li Zhao's plan may also be realized, Hedong will fall first, Li Jing may have to withdraw his troops, keep Hedong, in order to keep Guanzhong.

No matter what the people of the world think, Su Dingfang in Hedong is meticulously guarding the city wall, the Turks have been attacking for four days, 100,000 horses are frantically attacking Hedong City, all kinds of siege tools have been used, and even the Turks have built siege tools such as arrow towers, compared with the previous Turkic siege methods, the 100,000 Turks led by Qibi He Li and Ashina Simo are actually almost the same as the Central Plains. This is also the reason why Li Shimin left these 100,000 people under Hedong City.

Li Zhao's strength was originally inferior to the Turks, if these Turks were allowed to return to the steppe, the first thing that Jieli Khan, an ambitious guy, would do was to go south to the Central Plains and compete for the world.

There are too many places on the border between Li Zhao and the Turks, no matter how they defend, Li Yuan can only leave these 100,000 people in the Central Plains, and it is the best choice to lose both with Li Xin.

The blood on the city of Hedong has long dried up, there are Turks, there are also soldiers in Hedong, the city wall is full of arrow holes, and now it has entered the most difficult time of the siege war, both sides have gone crazy, although it has not yet reached the final moment, but in the face of the attack of 100,000 people, Su Dingfang still felt the pressure, he divided 50,000 people into five echelons, and went to the city wall for defense. Fortunately, the Turks thought that there were only 20,000 people in Hedong City, and when they came up, they thought that a wave could wipe out 20,000 people, so they just attacked the north gate, but they didn't expect that the other party's defense was so strong that he himself was killed and wounded countless times.

"Tunnels dug into place?" He Li was holding a copy of Sun Tzu's Art of War in his hand, and there was an old scholar next to him who was explaining Sun Tzu's Art of War. His face was gloomy. This book was snatched from a defender when he captured a small county town, and he always felt that the Central Plains people were cowardly, but after reading Li Shimin's soldiers, he found that the Central Plains people could use the city to resist the attack of the Turks, and sometimes the Turks who could still kill fell apart, not unreasonable, the civilization of the Central Plains made people yearn for it, and it also made people feel terrible.

One day he saw Li Shimin looking at Sun Tzu's Art of War. I couldn't help but grab a copy of it, but unfortunately, Sun Tzu's Art of War was too profound, Mo said that he was a Turk, even some Han people may not understand the meaning of this, so he specially caught an old scholar to explain Sun Tzu's soldiers and horses to him. This tunnel-digging attack was comprehended from Sun Tzu's Art of War.

"If you go back to the general, you can dig it up tonight." The soldier next to him hurriedly said.

"Okay, tonight we will send someone to attack Hedong City from the tunnel." He Li was very happy and looked at the city wall in the distance. Thinking about how to wreak havoc inside after attacking Hedong City tonight, he never thought that there was a shrill laugh next to him.

"Mr. Zhou, why are you laughing? Think we won't be able to capture Hedong City tonight? He Li snorted coldly.

"Su Dingfang is a rare leading general before King Tang. Let him sit in Hedong, which shows that Su Dingfang has a certain talent, and digging tunnels is the easiest means of attack, how could Su Dingfang not know. If nothing else, he must be waiting for you inside at this time. As soon as your soldiers show their heads, they will be killed. The old scholar said disdainfully.

"How is that possible?" Qi Qi He Li felt that he was humiliated, his eyes widened, he glared at the old scholar angrily, and said, "How can Su Dingfang know? ”

"Hmph." Mr. Zhou did not continue, but continued to explain the Art of War, the life and death of these Turks has nothing to do with him, even if he explains Sun Tzu's soldiers and horses, it only makes the general on the opposite side more confused, how to explain the Art of War, the old scholar does not know, but it does not prevent him from explaining, anyway, the guy on the other side does not know, since this is the case, then whatever he explains. The old scholar found that this method of explanation seemed to be much easier than when he was teaching by himself before. Teaching and educating people does not seem to be aimed at these barbarians.

"Alright, let's not go on." He Li whipped it over, and the old gentleman stumbled on the old man's back, and his face suddenly showed a look of pain, and there were many blood stains on his back.

As if he hadn't seen it, he strode out of the big tent, looking at Hedong City in the distance, not far from him, there were many soldiers transporting dirt outside, which was the soil produced by digging tunnels.

"Su Dingfang is commanding the battle at this time, how can he know the movement on our side? This old puppet is really damned, don't you think that General Ben really doesn't dare to kill him? He Li snorted coldly.

In Hedong City, Su Dingfang, Duan Decao, father and son were next to this urn, listening to the sound of the urn, a strange smile appeared on their faces, and a large amount of hot water had been prepared next to the three of them.

"This Turkic actually wants to dig tunnels to break into the city in front of us Han people, and I don't want to think about it, these things have been played for hundreds of years, and we can see his every move over there clearly, digging tunnels here, it is simply looking for death." Duan Zhiming said disdainfully.

"Don't underestimate the Turks, they have initially mastered a lot of siege methods, in the future they not only have the advantage of bows and arrows, but also the help of various siege equipment, our Central Plains people want to resist the attack on the grassland, it is becoming more and more difficult." Duan Decao shook his head, these days of hard work made him realize that the Turks were very powerful in riding and shooting, and more about the use of various siege equipment, which made Duan Decao also worried about the situation in the future.

"It's all that Li Shimin, if it weren't for him, how would these Turks understand these things?" Duan Zhiming said dissatisfiedly.

"Don't worry, these 100,000 people died under Hedong City, everything is the same as before. Li Shimin is probably more afraid than we are of the return of these 100,000 Turks. Su Dingfang looked at the tunnel under the city, the side was digging the tunnel, and the same was true here, because there was a moat outside the city east of the river, which determined that the Turks must dig a little deeper, of course, if the Turks were unlucky, maybe Su Dingfang was not needed, and the water in the moat would instantly rush into the tunnel, drowning all the soldiers who were working in the tunnel. Listening to this sound, I am afraid that it is already close to the moat, but in a few hours, it will dig under the city wall.

At this time, there was a sudden exclamation on the city tower, Su Dingfang and Duan Decao glanced at each other, and rushed up to the city tower quickly, but saw countless arrow towers in the distance appear again, these arrow towers are built very arrow towers, but they are better in number, at this time, the side of the arrow tower facing the city wall has been covered with wooden planks, which will increase the weight of the arrow tower, but it can make the soldiers climb more safely.

"The Turks have learned wisely." Duan Decao's face was much gloomy, the previous arrow tower was more than the arrow tower in front of him, and there were only a few soldiers on the arrow tower, as long as the soldiers on the arrow tower were shot, this arrow tower would be useless, but now one side is covered with wooden planks, which means that even if you shoot a few soldiers on the arrow tower now, I am afraid that you will not be able to stop the enemy's attack, and on the back of the arrow tower, I am afraid that there will be a wooden ladder to let the Turkic soldiers behind you climb up.

"Then burn it!" Su Dingfang said indifferently: "One arrow tower, two pours of stone paint are enough." Su Dingfang said indifferently, when Su Dingfang was defending Hedong, he thought of this, but he was not guarding against the Turks, but Li Zhao. Unexpectedly, the first person to deal with today was the Turks, which he did not expect.

Soon I saw the stones flying on the catapult and smashed towards the arrow tower in the distance, but the ten-pound stone smashed on the arrow tower, and the power generated was not as great as imagined.

"How many towers can be destroyed by such a small stone?" Ashina Simo said proudly.

"The Han Chinese can't resist our attack anymore." Qi Qi He Li also nodded, he launched an attack at this time to attract the attention of Su Dingfang and the others, so as not to be discovered by Su Dingfang The secret that he was digging a tunnel.

It's a pity that the two of them soon couldn't laugh, as one after another jar of stone paint smashed on the arrow tower, they saw a flame burning out of thin air, and soon set the arrow tower on fire, and there were bursts of screams in the raging fire, and the arrow tower about several feet high was burned clean in the fire, and even the Turkic soldiers who shot arrows in the arrow tower were also burned to death. The terrible screams spread to the entire battlefield at once, and the Turkic soldiers looked at the figures rushing in the fire, their faces showed horror, and they all stagnated, and they no longer dared to attack Hedong City.

"What's going on? Why does the arrow tower burn so easily? Qi Bi He Li said loudly, this kind of arrow tower manufacturing is his own invention, and even for this he feels very proud, thinking that such a cunning Han people may not be able to break through the arrow tower, but I didn't expect that the other party just burned the arrow tower with a fire.

"It's better to withdraw first." Ashina Simo was also very anxious, and hurriedly ordered people to retreat, and if he continued to burn like this, he was afraid that his arrow tower would be burned clean by the other party, although this thing was not valuable, but it consumed a lot of manpower and material resources to build. Although there are a lot of mountains and forests around Hedong, they can't withstand such consumption, and more trees are needed to build siege equipment, and now the distance of cutting down trees is getting farther and farther. Ashina Simo sometimes has a bad feeling in his heart from time to time. (To be continued......)
