In this regard, Yang Kuo is not afraid and still leads the army to attack.

However, something unexpected happened. The arrow plumes shot down from the wall and the blood of all the stabbed soldiers were black.

Yang Kuo understood that there was poison on the arrowheads of Beiliang.

He understood and ordered the withdrawal of troops.

However, on the Yongning mountain pass under the guard of Yougu Town, the archers in Beiliang still didn't stop shooting.

Yang Kuo finally ran away in a panic, and his soldiers and horses were also damaged.

At that time, Murong yuan, Su Yunchu and others were discussing the next marching plan with the generals in the camp. They had stayed in Yongning mountain long enough. Although Yang Kuo led the troops to attack, there was no actual progress. As the Northern Expedition army watched Yang Kuo lead the troops to attack, their inner desire to fight would increase over time, People who are always ready to fight and kill the enemy at any time should not be idle for too long.

However, before discussing anything, someone rushed into the camp halfway, "the prince, Princess and General Yang's soldiers and horses were injured by the poisonous arrow of Beiliang."

The generals were shocked when they listened to the poison arrow, and then they were angry. The two armies fought without poison on weapons. This is a tacit understanding and has been handed down all the time. Even if they played some small tricks in the battlefield, they would not do anything without character, such as poisoning on weapons. At this time, Beiliang even used poison arrows. It is shameful.

That's what Xiao Xiaozhi can use.

However, Su Yunchu and Murong yuan didn't react much. When they heard someone report, they both left the camp and went to the military medical camp.

In the military medical camp, Zhou Zong and Liu Shen are treating the soldiers wounded by poison arrows.

Many people were injured by poisonous arrows. Zhou Zong and Liu Shen were too busy. Su Yunchu came to the military medical camp and naturally went to help.

While helping, he also understood the situation and learned who was the general on Yongning mountain when Yang Kuo attacked.

Sure enough, it was Yougu. Su Yunchu knew that Gan Cheng would not do such things. Sure enough, Yougu came to Yongning mountain, and Beiliang was demonized.

Yang Kuo was also injured and scratched his arm by a poisonous arrow.

Zhou Zong and Liu Shen just drew swords and stopped bleeding for the soldiers. In addition, they sprinkled some common detoxification powder. Su Yunchu said, "Mr. Zhou, Mr. Liu, can you see what the poison is?"

Zhou Zong and Liu Chen shook their heads. "We haven't studied it yet, but it seems that it's not an ordinary poison."

Murong yuan followed Su Yunchu nearby, handed Su Yunchu scissors, gauze and other things, and said, "ah Chu has a lot in mind."

If it is really a poisonous arrow, then the attack of Beiliang will be subject to such indiscriminate means this time, and Yongning mountain is even more difficult to fight. First of all, the constant poisonous arrow has become a problem.

Su Yunchu only shook his head. After treating the wounds of several soldiers, seeing that all the people in the military medical camp arrived, he washed his hands and retreated.

"I can't see it, at least not yet."

After a pause, she picked up a small bottle and picked up some soldiers' poisoned blood. "We still need to go back and study."

The originally negotiated March plan can only stop here. Before the poison arrow is settled, Daxin goes to attack Yongning mountain, that is, eggs hit stones.

Liu Shen and Zhou Zong are dealing with the wounds of the soldiers. Su Yunchu can only develop the antidote by herself. These things are used to doing. Besides, she has always been dealing with the medical affairs in the army.
