Gai Yanxiao's mistake caused huge trouble for Hua Mengjun.

Originally, the number of Hua Meng's army was only 10,000, and these numbers were enough for the defenders of Pingshan, especially when the Goryeo army was caught off guard, but even Hua Meng himself did not expect that his onslaught could attract 15,000 enemy troops, and the sharp change in the number of enemies and friends reversed the battlefield situation.

Hua Meng had to switch from offensive to defensive, and he couldn't take a step back, because the main force of Andong Protectorate had already poured out, and if he lost, then Pyongyang would basically be in an empty state, and if it eventually evolved into an exchange of venues between the two sides, then this military operation would be a complete failure. Therefore, Hua Meng had to stay where he was to resist, how badly he had beaten the defenders of Pingshan before, and now how badly he was beaten by the Goryeo army. And at this time, Cheng Yun's troops arrived.

Cheng Yun was worthy of being a veteran of the battlefield, he deliberately chose to arrive at the battlefield at night, and taking advantage of the cover of night, he ordered each soldier to hold two torches, and disguised the Goryeo army, which numbered less than 2,000 people, into a force of nearly 4,000 people. This had a great negative impact on the Hua Mengjun, who was already in a disadvantageous situation, and the onslaught that followed the next day made the Hua Mengjun even more convinced of this, which prepared him to lead the army to escape at night again, and when Hua Meng found that Cheng Yun had led the Goryeo army out of a day's journey. Hua Meng led his troops to pursue later, but he encountered the blocking force sent by Cheng Yun and used the terrain of Pingshan to drag him down, so that instead of narrowing the distance between the two, Hua Meng pursued farther and farther.

At this time, the number of Chengyun's army reached nearly 20,000 people, and it was difficult for even Gai Yanxiao's troops to stop him. The only thing he wanted to avoid was being held back by Gai Yanxiao and allowing Hua Meng's army to catch up and flank his troops. So he gave a death order to the troops. It was necessary to march as quickly as possible to the city of Xiou, and to discard everything that was not a march.

It's a pity that Chengyun missed one. That is the existence of the Tiger Guard Battalion on the Gaoding side. Of course, he can't be blamed for this, because the lack of information makes him unaware of the movements of the Tiger Guard Battalion.

Originally, after cooperating with Gai Yanxiao to break through the coastal defense line, Gao Dingbian led his troops to enter a state of rest on the spot, after all, the troops were exhausted after several months of fighting, and he took all the credit for the first phase of this plan, so the veterans should have the opportunity to establish meritorious deeds.

However, the news that came later made Gao Dingbian more and more unable to sit still, because two days after Gai Yanxiao attacked Kaecheng, the enemy army suddenly abandoned the city, and Gai Yanxiao began to search for the enemy's movements.

The enemy army was already preparing to abandon Kaesong. This was Gao Dingbian's first feeling when he got the news. If Goryeo plans to resist, it is impossible to give up after holding on for so many days, it is clearly a small force used to hold down Gai Yanxiao! Otherwise. It is very difficult for a large army to escape Kaesong without showing a trace. This shows that Choi Jianjiang, the king of Goryeo, is no longer in the city, so the movement of this small force is not a concern at all. Gai Yanxiao's judgment made a serious mistake! He also thought that Cui Jianjiang was nearby, and he was bent on capturing this king!

Now that Choi Jianjiang has fled, the most important thing at the moment is not to capture the king, but to eliminate the living force of the Goryeo army. Therefore, whether the main force of Goryeo in Pingshan can be encircled and annihilated is the key to the success or failure of this military operation!

Thinking about this layer, Gao Dingbian immediately canceled the rest plan of the Tiger Guard Battalion, and immediately set out for the direction of Pingshan. As expected, the Goryeo army in Pingshan successfully got rid of Huameng and was rushing south. Gao Dingbian did not hesitate any longer, and immediately led the army to post it.

When the shouts of the Tiger Guard Battalion came from the rear army, Cheng Yun only felt a tingling of his scalp. He had already learned the strength of this army, and it was obvious what kind of situation it would turn into when the Tiger Guard Battalion assaulted from the rear at this juncture. Gao Dingbian's troops were insufficient. Therefore, his aim was to disrupt the sequence of his troops and scatter the whole force again, so that he could not only take the opportunity to annihilate some of these small forces. It can slow down his pace even more, so that Hua Mengjun and Gai Yanxiaojun have time to encircle themselves. He must be stopped! This is Chengyun's determination. But it's one thing to think, it's another thing to do it. The mobility of the Tiger Guard Battalion has long been deeply rooted in the hearts of the people. It is almost impossible to encircle and destroy it, so sniping the enemy will be a more practical solution. The problem is that today's Gao Dingbian is undoubtedly a military general who is difficult to find opponents in Goryeo, since he single-handedly killed the legendary Goryeo military general Li Chenghui, I am afraid that any Goryeo military general will not have the courage to fight against him, even Cheng Yun has to admit that he has a big gap with this young general.

In order to stop Gao Dingbian, Cheng Yun selected six young Goryeo generals who were known for their bravery to face this formidable opponent with him, and he also arranged for four archers to wait for the opportunity to shoot him. After making such preparations, Cheng Yun led two thousand elite soldiers to the Tiger Guard Battalion.

As soon as he met Gao Dingbian, Cheng Yun didn't say a word, and immediately surrounded him with the six generals in the middle, swords and guns. Gao Dingbian was not afraid of the combined attack of the enemy's seven generals, holding up his spear to resist left and right, protecting himself and his horse below, without the slightest flaw. The sergeants of the Tiger Guard Battalion saw that the Lord would be surrounded and desperately wanted to come to the rescue, and the Goryeo soldiers were also desperately resisting the attack of the Tiger Guard Camp and buying time for their generals. The battle suddenly became white-hot.

Seeing that more than 20 rounds had passed, Gao Dingbian finally caught a gap, stabbed a Goryeo military general off his horse with one shot, and then avoided the two spears on the left side, and swept another enemy general off his horse with a backhand. With two less opponents, Gao Dingbian suddenly felt much more relaxed, and after five or six moves, one shot pierced the throat of the third person, and another shot stabbed the fourth person in the abdomen. The remaining two Goryeo generals were shocked when they saw it, how could they dare to fight again? One by one, they turned their horses and fled. Gao Dingbian didn't relax, he used the handle of the gun to pull away Chengyun's knife, and took advantage of the situation to let go alone, picking the head of the enemy general who was walking slowly into the air!

However, at this moment, four feather arrows suddenly shot towards Gao Dingbian, Gao Dingbian used his gun to open three of them, and the fourth shot him in the right chest!

Gao Dingbian's body shook backwards, and at this time Cheng Yun had already slashed with a knife, Gao Dingbian struggled to dodge the knife, but the war horse under the crotch was cut off by this knife, the horse fell to the ground, and Gao Dingbian also rolled off the horse. (To be continued.) )
