At this time, the sharpest weapon of the Tang army, the trebuchet, was launched at this time, but in order not to hurt the Tang army, they did not use fire oil as before, but used the most traditional weapon - boulder, and the target selected was slightly farther away, and was selected a little in front of the dock, so that it would not bombard the dock, and it would not take too much experience to repair it afterwards.

Although with the range of the trebuchet, it was almost able to reach the opposite bank, but according to the plan, the long-awaited Hexi Army would surprise the Xiqi coalition army from behind, so in order not to injure the friendly troops, they did not set the target of the trebuchet to the opposite bank at the beginning.

I saw that a huge boulder like a hut smashed into the crowd behind the Xi Qi coalition army, so that countless cavalry and even men and horses were smashed into meat sauce, and the rolling boulder still took the lives of many cavalrymen, and this was more than one boulder. Although the Tang army had no plan to attack the city at the beginning, in their opinion, the Xi Qi coalition army was very strong, and it was impossible to break and flee to the Song Desert to start a defensive battle, so they did not prepare many boulders, but after learning from Ye Chengcheng's plan to fight a defensive battle in the big camp, they quickly transported all the boulders stored in the rear baggage to the big camp, and now is the time to come in handy.

When they learned that the former army of the Xiqi coalition army had been beaten out of the camp gate, the generals of the Tang Army led by Wang Zhongsi walked out of the tent and came to the gate of the camp. And these Xi Qi coalition forces, who were like wolves and tigers in their impressions in the past, and their combat effectiveness was extremely terrifying, but they were beaten to the point that they lost their armor and ran away, to put it bluntly, in the final analysis, most of them were the credit of Ye Chengcheng and his two subordinates.

Wang Zhongsi looked over his head, only to see Bai Quan standing back on the flagpole again at this moment, paying attention to the battle situation below, and shooting again from time to time, every time a flying knife was shot, an officer of the Xi Qi coalition army turned over and dismounted, which made him really admire, and at the same time secretly frightened, fortunately such a person is a companion and not an enemy, otherwise, it would be the officer of the Tang Army who was sniped by one person.

In fact, as early as when the two chirpings of Baiquan and Ye Tingcheng were released, Huan Chenyu beside Ye Tingcheng was already waiting for the opportunity to move, he used his fist as a weapon, and three times five divided by two to break the more than ten giant trees on the Sanggan River, and many cavalry who were crossing the river fell into the water, which made the Xi Qi coalition army unable to cross the river again, and the connection between the front army and the rear army was completely cut off, and the guys who had crossed the river were as helpless as if they had fallen into an isolated island.

And on the opposite bank of the Xi Qi coalition camp, the situation is also not in their favor, after Ye Chengcheng's chirp sounded, from the northwest suddenly dusty, it seems that at least tens of thousands of cavalry are riding horses together, and the Xi Qi coalition army who got the news immediately became nervous. The big chief Li Huaixiu suddenly decisively ordered the front army to speed up the charge, instead of letting people defend the rear, he told his subordinates that these were just feint squads separated from the Tang army, the number was only thousands, and there was no need to worry at all, plus the Tang cavalry had always lost more than won in the past when they clashed with them, so they also began to light the enemy as Ye Qingcheng expected, except for the last group of horses that turned their heads to meet this Tang army, the rest of the cavalry was still waiting in line to cross the river.

However, Huan Chenyu's sudden destruction of the giant tree suddenly overwhelmed these remaining Xi Qi coalition forces, and at this time, the last group of guys finally fought with the Tang army that came to sneak attack, but when it came to the fight, they found that the number of the other party was not only the thousands of people Li Huaixiu said, but should be tens of thousands, and the other party was different from those cavalry in the Central Plains, everyone was good at horsemanship, and their combat effectiveness was quite strong, and they were not even under them, such a Tang army had been hiding near them, and their patrol posts did not find these Tang troops, it was incredible。 In addition, the Xi Qi coalition army that attacked the Tang army camp on the other side also began to show signs of retreat, and the Tang army began to use trebuchets again, causing them heavy losses, which made the guys who had lost contact with the other side look at the situation on the other side, and the Hexi army had already attacked the camp, which made them even more overwhelmed.

Li Huaixiu, who they pinned their hopes on, disappeared at this moment, and the Xi-Qi coalition army was suddenly in chaos, although those Khitan warriors appointed by Li Huaixiu as generals wanted to control the situation, but they had no choice but to obey their command in such a chaotic scene, and none of the cavalry below obeyed them, and they were unwilling to obey their commands, and suddenly the command system of the entire Xi-Qi coalition army fell into a state of paralysis.

The combat effectiveness of the cavalry of the Hexi Army is really not blown, and the Khitan who fought with them was defeated by them in the last few strokes, which is not only because of the number and combat effectiveness, I am afraid that it has a lot to do with the incompetence of the generals and the disobedience of the cavalry below, even the Hexi Army is because they are the last formation, so they have to fight, and the penultimate formation is like the previous formations, if it is not the last rout, they will not care about the Hexi Army at all, just like their colleagues, these guys were defeated without much effort。

At this moment, the Xi Qi coalition army finally panicked and fell into complete chaos, unable to even maintain its original formation, and was engulfed by the rolling Hexi army.

Their big chief, Li Huaixiu, was still standing on top of the tent with Ye Tingcheng and the two of them at the moment, coldly watching all this happen, although all this was planned by him, but Ye Tingcheng still sighed with emotion, and once let him be a cynical Beiyi, who was still caught quickly, was slaughtered by the Tang Army in front of him at this moment, like cutting melons and vegetables, which made him feel more and more that this was too unreal.

The surrounding Khitan warriors and attendants had already been lying on the ground with their heads in different places, blood all over the ground, and it seemed that a few of them had done it, which made Li Huaixiu, who was standing beside them, still have some heart palpitations. Just now, Ye Tingcheng and Huan Chenyu were making a move, he just gathered these guys together, what kind of strength this body has to control the brain, he knows best, after comparing in the same direction, he knows how terrifying these two people are, not to mention that one of them has not started cultivating at all, and the other is just a mortal incarnation used, no matter how much he cultivates, can he really catch up with them one day?
