When Helian Bobo saw this scene, he was very surprised and shook his head bitterly and said, "It seems that there should be masters in the Han army, which makes my skills unable to be used. No wonder Yue Fei is so confident."

"So that's it. It seems that there are indeed many talented people in the Han army, but so what? Can they break through my Tongwan City?" Liu Yuan was very proud of his Tongwan City. Then he thought of something and said to Helian Bobo: "Helian, I really shouldn't have been like you at the beginning. I apologize to you. Now I think about it. Although you seem to be doing something extreme, after all, I have built such a solid Tongwan City. Without it, I would not be as comfortable as I am now, and it is impossible for me to defend this city under the attack of Yue Manzi."

When Helian Bobo was building Tongwancheng, he was too cruel and there were too many deaths, which caused Liu Yuan's dissatisfaction. For this reason, Liu Yuan found Helian Bobo and the Great Thunder, and severely rebuked him. From then on, he deliberately alienated Helian Bobo. However, when he heard the news that the Han army generals attacked Tongwancheng, he regarded Tongwancheng's defense as the greatest reliance, especially when Helian Bobo's "brutal" skills could not be used, Tongwancheng's defense became the only reliance. At the critical moment of life and death, he naturally put away the false benevolence and righteousness to buy the hearts of the people, and at the same time apologized to Helian Bobo so that the two could cooperate more intimately.

Helian Bobo naturally would not mind when he heard this, and said in fear and fear: "What did the Grand Marshal say? Let's talk about military positions, you are the Marshal, and the last general is the deputy general, and you should serve the Grand Marshal wholeheartedly. From the tribe, you are the Grand Marshal of my Huns. As a great master, I naturally need to serve the Grand Marshal. Even if the Grand Marshal kills me, I dare not frown, let alone just blame a few words?"

Liu Yuan opened his mouth and was about to say something, but suddenly his expression changed drastically. He pointed to the front and said, "Then, what is that?"

Helian Bo was very excited when he saw Liu Yuan apologizing to him. He was about to say something, but he saw Liu Yuan say this. He looked in the direction of Liu Yuan's finger and saw hundreds of strange equipment being pushed out in the Han military camp. Those equipment looked like stone throwing cars, but they were a little different from stone throwing cars, because the end of this equipment was originally shot by stones, but a wooden wheel, with a circle of stone-loading cars hanging on this wooden wheel.

Then at a command, a soldier pulled the rope of the catapult cart, and the huge wooden wheel turned, and then the stones on the wooden wheel continued to hit the city.

Dozens of stones were projected from a car, and hundreds of catapults were moving together, which was equivalent to thousands or even tens of thousands of stones flying towards the city. In an instant, the city was full of stones. Not to mention the Hun soldiers, even people like Liu Yuan were trembling and hiding behind the female wall, and they did not dare to show their heads.

"That's so hateful. I really didn't expect that the Han army would actually have such powerful siege weapons. We still underestimate the other party." Liu Yuan said with a pale face and gritted his teeth behind the female wall.

Helian Bobo didn't say anything. He was very nervous. He didn't know if the city wall he supervised could withstand the crazy attack of so many stones.

Fortunately, after the attack, except for hundreds of unfortunate Hun soldiers who were killed by stones, everything was safe and sound. Although the city walls were smashed into pits, they still stood firmly.

This made Liu Yuan, Helian Bobo and others overjoyed. At the same time, they were more confident, so they stood up and wanted to see the expression of the Han army commander Yue Fei, and then mocked him a few more words.

However, before they could stand up, they suddenly heard the sound of breaking through the air again. Everyone was startled and squatted down again. Only then did they see dense crossbow arrows flying over. Although they were nearly 150 steps away, the crossbow arrows were still very powerful. Liu Yuan would not doubt at all that as long as they were shot, these crossbow arrows would definitely cause huge damage to people.

"It's so exaggerated that the Han army's crossbow arrows can even exert such power, right? Is there thousands of archers in the Han army who can use strong bows and hard crossbows?"

Liu Yuan's heart was shocked and his face was filled with disbelief.

After finally avoiding the rain of arrows, Liu Yuan was about to stand up to observe the enemy situation, but unexpectedly the sky turned dark again. When he opened his eyes and looked closely, he found that it was a stone thrower shooting stones again.

Liu Yuan knew that although this thing had a low hit rate, its lethality and destructive power were indeed strong. As long as it was hit accurately, the flesh and blood could not resist it at all, so he had to dodge again in desperation.

After hearing the sound of a catapult cart hitting the city wall and feeling the feeling of an earthquake, Liu Yuan's heart became nervous again, fearing that the city wall would be overwhelmed and destroyed by the stones.

However, after surviving this round of catapults, he found that the city wall was still safe and sound. Then he felt relieved and laughed: "Helian, the city wall you built is indeed An Ruotai Mountain. After this battle is over, I will definitely report your military achievements to the leader and recommend your method of building the city wall to the leader."

Helian Bobo hid behind the female wall and slowly stood up. He was about to bow to Liu Yuan to express his gratitude, but his expression changed suddenly. He pointed to the city and said, "Great, Grandmaster, no, no, the Han army is attacking."

"What? How is this possible? They are still separated by caltrops and tigers. It takes a lot of time to remove these things, right? How could it be attacked now?" Liu Yuan was shocked when he heard this. He quickly stood up and looked down at the city. It didn't matter when he saw it. He immediately gasped, because there were rows of strange cloud ladders in front of the Han army. These ladders were very tall, with a base of a hundred steps away from the city wall. However, when they extended slanted, the other end had already hit the city. The Han soldiers were now stepping on the cloud ladder and running hard towards the city. Because the Han soldiers had used catapults and crossbows to attack in turn, taking advantage of the opportunity that the Huns did not dare to show their heads, not only did this large cloud ladder be deployed, but the Han soldiers also ran along the cloud ladder for most of the journey. The Han soldiers in the front were only ten steps away from the city head!

"Get up quickly, the Han army will rush to the city and stop them at all costs!" Liu Yuan knew that his biggest reliance at present was the solid city wall. Once the Han army attacked the city wall, it would be equivalent to losing the cover of the city wall. In that case, how could they be the opponent of the Han army like a wolf or a tiger?
