Qin Feng came to the front of the horse's corpse, squatted down and took out an extremely sharp knife from her medical case, and placed it in front of the horse's corpse. All of the officers stared at Qin Feng's hands, but Qin Feng did not do anything.

"Qin Feng, what did you see?" Xuanyuan Zhiling stared intently at Qin Feng, his expression carrying a tinge of nervousness. But Qin Feng did not say anything, and looked at it with the eyes of the horse, her face revealing a faint trace of suspicion. Qin Feng opened his spirit stallion's mouth and noticed its mouth. She frowned and stood up.

Qin Feng sighed as she wiped her hands with a white towel. With a serious expression, she said, "I first judged that the death of the warhorse was due to eating the wrong thing, which is food poisoning." Qin Feng's words immediately caused everyone present to turn their gaze towards Second Prince.

"The wrong thing to eat must be because you ate my food? My food is the best food provided by the palace, so why is there a problem? " Xuanyuan Mocheng was also puzzled, his expression was filled with complex emotions. Just as Xuanyuan Mocheng finished speaking, Xuanyuan Zhiling said coldly, "You don't need to be anxious to explain yourself right now. After the military doctor dissected the warhorse, the result will naturally be revealed. If you didn't do it, then you wouldn't even need to explain yourself before we know that you didn't do it." After Xuanyuan Zhiling finished speaking, the entire audience quietened down, and everyone listened to Qin Feng continuing to inspect.

"The eyes of the war horses are red, and their tongues basically show signs of peeling, showing a faint pink color, so I can tell that the war horses must have eaten a slightly corrosive poisonous plant, causing their deaths. But I still need to dissect the poison grass on the war horses, so right now I have no way of determining." Qin Feng explained very professionally, but just as she said that, the generals behind him started discussing, and some of the more straightforward generals directly stepped forward to take responsibility of Xuanyuan Mocheng: "Second Prince, the wangfei has already found out that the warhorse died from eating poisonous grass by mistake, and the warhorse only ate the food you brought over earlier, you still don't admit that you caused the horse's death?"

Second Prince Xuanyuan Mocheng only maintained his silence when he heard the general's ridicule or occasionally revealed a face of contempt.

Qin Feng picked up the dagger and cut open the horse's stomach, causing everyone's gaze to gather on her hand. The moment the horses' stomachs were opened, everyone was shocked. This was because the horses' internal organs had all turned into a pool of blood and were extremely rotten. When everyone saw this scene, they all turned their heads and began to vomit. A stinky stench was assaulting their nostrils. But Qin Feng did not react at all.

"The horses' stomachs have already been corroded by this corrosive poison, which is why they are showing such a high degree of corruption." Qin Feng said indifferently, but everyone else had puked until their faces were white. Xuanyuan Zhiling and Xuanyuan Mocheng's faces were also extremely ugly, but they did their best to not lose control of themselves.

Xuanyuan Zhiling's face was deathly pale, but he tried his best to remain calm as he asked, "Is there any corrosive properties within the rations the Second brother brought?" When his subordinates heard Xuanyuan Zhiling's words, they immediately went to check the food that Xuanyuan Mocheng had brought over. In the end, all of the food that Xuanyuan Mocheng had was just ordinary food.

"Who knows if the food he gave to the warhorses was grain or not?" The other generals were still a little unwilling to let him go, because Xuanyuan Zhiling was now the great marshal, so compared to the Second Prince, they were more inclined to do so by the emperor. But when Xuanyuan Mocheng heard this, he only coldly smiled and remained silent.

At this time, Qin Feng took out a grass root from the horse's abdomen with a pair of pincers. Qin Feng frowned and said: "This type of grass should have a very attractive smell, I don't feel it when the warhorses eat it, but this grass will erupt in the belly of the warhorses after four hours and start to corrode their internal organs."

Once Qin Feng finished speaking, everyone sucked in a breath of cold air, because this kind of grass could be said to be extremely vicious. But according to Qin Feng's calculations, the food that the horses should have been eating was when they were just setting up camp four hours ago, so it should be local food.

"Immediately go outside the camp to see if there is any weird-looking grass. If there is, bring it back to me." Qin Feng said to Qin Wu who was standing beside him, upon hearing her words, Qin Wu immediately ran out of the tent. After a little while, Qin Wu ran back from his tent with a blade of grass in her hand.

Qin Wu passed the grass in her hand to Qin Feng. That blade of grass was the same as the rest of the grass, they were all green, so it didn't look very special at first glance. Then, someone from the crowd asked: "Qin Wu, is this grass that special? Why do you think that this grass is poisonous? "

"This grass is different from normal grass, because other plants have roots, but these plants have no roots." When Qin Wu said this, her expression was somewhat complicated. Both Xuanyuan Zhiling and Xuanyuan Mocheng's expressions became slightly ugly, because they had all realized that the grass was something that had been thrown on the ground by someone else.

"No roots? That means someone intentionally threw the poisonous grass on the ground for our war horses to eat? " The soldiers were frightened because they realized that they had been tricked by the Huns the first time they came here. They were a bit ashamed, a bit angry, and a bit solemn.

Qin Feng held the grass in her hand, and a faint look of calculation flashed across her face. She suddenly said with a smile: "Actually, we should thank them, because they let us know their secret." Qin Feng's words suddenly stupefied everyone present, and none of them knew what she meant.

"Princess, are you angry? Our war horses have been poisoned to death, and you still think that's good? " However, Qin Feng did not mind at all as she smiled and said: "There are only four hours worth of effects from this kind of grass, and it just so happens that we have to wait four hours for our warhorses to consume this medicine. Four hours later, they finally died, so it means that they just scattered the poison grass on the ground not too long ago."

After Qin Feng finished speaking, these generals, and even Xuanyuan Mocheng and Xuanyuan Zhiling, were brought into deep thought by his words. They still did not fully understand, so Qin Wu asked puzzledly: "But when we arrived, we did not see any Huns at all." Qin Wu's words were exactly the question that everyone wanted to ask, but Qin Feng said with a faint smile, "This is their secret. Why didn't we see a single young man when we first entered?

When Xuanyuan Zhiling heard this, he suddenly understood what Qin Feng meant, his eyebrows knitted together as he asked: "Are you saying, that those old men did not go to the streets to beg with baskets, but were all disguised as old people by the Huns to deceive us?"

"Their real purpose is to plant poison plants on the streets?" Qin Wu said as she followed Xuanyuan Zhiling. It occurred to them that their defenses were too low, and that the Huns were ready for their arrival.

Qin Feng laughed indifferently: "Actually, all the people in this city have long been Huns, none of us are alive, if not killed, we have escaped, the remaining may have become captives, their appearances are different from us, it is easy for them to be recognized if they pretend to be young, we can only pretend to be elderly people with white beards."

"They're still pretending, so we might as well play along!" Qin Wu said as she gritted her teeth. There was a trace of anger on her face, she did not expect the Huns to be so vicious, to actually do such a malicious thing.

Qin Feng nodded her head and said: "The Huns have always been known for their courage and battle prowess, but this time they actually used such a despicable method which is beyond our imagination, but dealing with them is your problem, I am only an army doctor, if you are injured, do not fight for it, and come back immediately to treat it." After Qin Feng finished speaking, she sent people to clean up the corpses of the horses.

Everyone dispersed, before they left, Xuanyuan Zhiling had already informed all of their generals that they were to gather at Grand Commander Camp tomorrow morning, and they were to arrange a strategy together.

"Fourth brother, you have truly wronged me this time. Even if I were to compete with you, I would not joke around with the fate of my country." Xuanyuan Mocheng said with a complicated expression, when he said till here, Xuanyuan Mocheng seemed to be looking at Qin Feng intentionally, but Qin Feng did not look at him in the eye.

Because Xuanyuan Zhiling had misunderstood him earlier, they were prepared to treat drinking a cup as a form of apology. This was a rule in their camp, but in truth, Xuanyuan Zhiling didn't want to see Xuanyuan Mocheng at all, especially since he was also present.

"This marshal is also tired. After finishing this cup of Second brother, you can go back to your own tent to rest, right?" Xuanyuan Zhiling had already left before he had raised his cup of wine, so he didn't say much as he drained his cup of wine. He then said with a complicated expression on his face, "Fourth brother, if one day you find out that Royal Concubine is in love with me, will you let go?"

The way he looked at Xuanyuan Mocheng instantly became extremely sharp, but Xuanyuan Mocheng didn't seem to mind in the slightest. Instead, he gave a bland smile and said, "Don't say that's impossible, because if I want Qin Feng, she'll be mine sooner or later."

Qin Feng sneered: "What do you think I am?" Finished speaking, Qin Feng had already lifted up the Grand Commander Camp's door and left, leaving behind Xuanyuan Zhiling and Xuanyuan Mocheng, whose rooms were filled with the smell of gunpowder.
