Feiyan chased the man in black, and soon caught up, whether the man in black was riding a horse or doing light work, he was not as fast as Feiyan, Feiyan was clean and neat, and he slashed the man in black in a few rounds, Feiyan knew that this person was a master of using Gu poison, so he searched him.

Feiyan found that the man in black was carrying two things in addition to Xun and weapons, one was an antidote, and the other was like a waist card, but it looked strange.

Feiyan picked it up and immediately returned, entered the camp, and saw Wanli sitting on the ground, the military doctor was bandaging his wounds, Feiyan is a person who practices martial arts, naturally understands the severity of the sword injury, and sees Wanli's lips are pale, naturally caused by excessive blood loss, presumably Wanli's wound should be very deep, and walked to the front, Feiyan first inquired, and saw that Wanli had no worries about his life, this time he was relieved.

"What about those soldiers who were poisoned?" Feiyan asked the officer next to him, and the officer on this side didn't react for a while, and asked puzzledly: "Miss Feiyan, what did you say?" Feiyan explained: "What about the soldiers who went crazy before?" Only then did the gang know, pointed to a few corpses behind them, and said to Feiyan: "This is." Feiyan walked closer to check, and it turned out that although these soldiers had some swords in the fight with Wanli, they were not enough to kill, and it was obvious that they had been poisoned.

Feiyan had heard her brother say at home that the most powerful Gu poison on the rivers and lakes was that after the person who went under the Gu died, the person who was in the Gu would die.

Feiyan explained to Wanli and them, and these generals also felt incredible, Feiyan then explained: "There is nothing strange about this, in fact, their death is not necessarily related to the death of the person who went down to Gu, in fact, the real mystery is in the voice of the person who is under the Gu, this kind of Gu is controlled by the voice of the person who has been under the Gu for a certain period of time, which can ensure that the person in the Gu can live for a while, and the voice of the person just now was interrupted, so it led to the instant outbreak of Gu poison in these people's bodies, resulting in poisoning death." Wan Li said: "Oh, I see, Miss Feiyan, I think this group is very dangerous, can you help me to check their details, I will order the army to retreat, and leave the way of contact when the time comes, so that you can follow the trail to evacuate." Feiyan agreed, turned around and went out of the camp, straight to the enemy camp, this Feiyan was still thinking about the identity of this group of people on the way, but General Wanli also entered her sight, the previous Feiyan did not know the world, and now she has experienced a lot, the person she admires most in this life is Chaoping, but now the impression of Wanli is also very good, she knows that these soldiers in the case of killing Wanli, he did not kill them, and captured, especially admire his virtue of loving soldiers like a son.

Feiyan thought that she must find out clearly, if such a good general and such a well-trained army win or lose in the military formation, it would be fine, and this kind of mysterious person who used Gu to act secretly could not be harmed.

After Wanli was bandaged, he instructed the guards around him to settle the dead and wounded soldiers, and then raised the tent to gather the generals of each camp to discuss important matters.

In the camp tent, Wan Li said: "Generals, I know that you are all ready to retreat, but this group of enemies is so deceitful, poisoning our soldiers, and delaying for half a day, now the enemy's spies must have been lurking around the camp, we should not withdraw our troops now, the sky is cloudy today, and it is already the end of the month, we just take advantage of the night to retreat." A general on the side asked, "General, will the enemy notice that we are making such a big move?" Wan Li nodded and said, "Yes, if the enemy sees that there is no movement in our camp for a long time, he will be discovered if he comes to visit the camp at the risk of death, but it doesn't matter, we will let them be fooled." After saying that, Wanli explained the plan as a whole, and then these generals went to prepare one after another.

Feiyan came to the camp of the Liao army, and saw that there was no one inside except the Liao army, and Feiyan guarded for a long time, but still didn't see the man in black come out.

Feiyan thought to herself, didn't these men in black go to the toilet? Why didn't they leave the camp, it's really strange, are they leaving?

Feiyan carefully looked at everyone walking around in the camp, and suddenly saw a few soldiers coming out of the camp, these soldiers attracted Feiyan's attention, they were obviously different from other soldiers, Feiyan could feel that they were not weak in martial arts, these people were riding horses to get out of the camp, Feiyan did not act rashly, and followed them all the way, they were going to the direction of the Wanli military camp, Feiyan followed closely behind, these people met with a few Liao army horses outside the Wanli military camp, Feiyan did not catch them, and kept guarding, at this time Feiyan saw that the Wanli camp was brightly lit, and there was nothing unusual about several camps, but it felt like there were a few fewer tents than before, and it was already night, and there were clearly guards in this barracks, because there were dark shadows shaking in the distance.

This group of people stayed here until midnight, and they didn't feel anything unusual, but they felt that there were not as many patrol soldiers in the camp as before, Feiyan clearly saw that these people were suspicious behind him, Feiyan thought that if these people went to find out the news, she didn't have to follow, as long as they guarded their retreat, none of these people in front of them could escape, but they didn't expect that these few gangsters with strong martial arts could make all the horses around this place appear.

Some of the people ordered a few spies to go down to check, Feiyan saw that these spies had just walked halfway up the mountain, and when they were about to arrive at the barracks, the whole barracks remembered the movement of the drums, and the drums would only be remembered when they sent out troops, and these scouts immediately retreated in fright, thinking that they were going to send troops, so frightened that they didn't dare to move, and lay on the hillside for a long time, and when they reacted, it had been half an hour since they returned to these black-clothed people, and these black-clothed people also wondered why they were beating drums in the camp in the middle of the night, was it to shock the Liao army camp tent in the distance, although the distance was not close, but in this large camp of thousands of troops and horses, several big drums played together, and the sound shook the sky, the Liao army on the opposite side can be heard.

The men hesitated for more than two hours, and when the day dawned, they rushed to the camp to check that the drums that had been sounding all night were caused by the beating of the drums of the tied sheep.

One of the men in black said, "Oh no, we've been tricked. At this moment, Feiyan appeared, appeared behind them, and said: "You barbarians, you don't know the art of war at first glance, this is called hanging sheep drumming, your generals can't compete with our Song army, hurry back to the depths of the desert." The Liao army was so angry that they slashed at Feiyan with their swords.
