After a discussion within the Grand Commander Camp, in the end, they still decided to let Qin Feng take the risk and poison the enemy's water source. Although Xuanyuan Zhiling was unwilling to let this go, in order for the army to be able to defeat the Huns in one fell swoop, he was still determined to take the risk. In the end, Xuanyuan Zhiling could not force Qin Feng, so he had to let her go.

The night was destined to not be peaceful. The pitch-black sky curtain firmly shrouded the entire world, and Qin Feng donned a set of night clothes. She was prepared to take advantage of the dark night wind to go to the enemy's water source to poison them. After everything was prepared, Qin Feng was about to open the tent and head towards her destination. Qin Feng raised her head in surprise. It was Xuanyuan Zhiling.

"Preparing to leave so soon?" Xuanyuan Zhiling sized Qin Feng up from head to toe. Seeing that Qin Feng was already wearing night clothes, she could not help but frown and ask. Qin Feng nodded, and said with a resolute tone: "When should I go? There's no moon tonight, so I won't be easily exposed. "

After Qin Feng finished speaking, complicated expressions surfaced on her face. Xuanyuan Zhiling sighed lightly, "This marshal orders you to complete the mission smoothly, or else this marshal will never let you off lightly!" Xuanyuan Zhiling's words were extremely stern, but they were accompanied by a slight tremble. The moment Qin Feng's gaze made contact with his eyes, Xuanyuan Zhiling turned around, unwilling to look Qin Feng in the eye. It was as if she was intentionally avoiding some sort of emotion.

"Don't worry, even if the mission fails, I will absolutely not cause you any trouble." Nodding her head, maybe he was only concerned about the success or failure of the mission, Qin Feng's heart slightly sunk, as though a stone was pressed on her heart. Opening the curtain, Qin Feng did not even say a word of farewell.

Xuanyuan Zhiling heard the sound of the curtain being drawn, and anxiously turned his head to explain, but did not give chase even though he opened his mouth wide. His nails dug into the flesh of his palms, the piercing pain made Xuanyuan Zhiling frown slightly. However, the pain in his heart far surpassed that of his physical body. He felt as if his heart was bleeding.

Qin Feng walked out of her tent and looked up at the pitch-black night. Dark clouds were presumably going to rain soon, so she couldn't help but let out a light sigh.

The ancient well in the middle of the night was dark, and there was a lack of water source in the border area. Only a few wells were available for human consumption. Qin Feng had already found the locations of these wells long ago, and she knew the exact locations of the wells that the Huns would use to drink. Qin Feng had been very careful on the way. Before she left, she had sent two soldiers with her, because doing this would guarantee her more. The few of them arrived at the well and found a secluded corner to hide in.

"Princess, are we going to take action now?" The two lackeys asked carefully, their expressions showing that they were slightly nervous. Hearing this, Qin Feng lightly frowned: "Even if I go, I'll be the only one to go. Otherwise, it'll be very easy for me to alert the enemy." When Qin Feng said this, her clear eyes carried a stubbornness and perseverance that was unique to her.

"But wangfei, isn't it too dangerous for you to go by yourself?" The two underlings wanted to persuade Qin Feng, but when Qin Feng heard this, she scolded them coldly: "If I go alone, even if I get caught, you can all go back and report it, but if the three of us move out at the same time, it would all be for naught." Qin Feng's voice was mixed with a trace of coldness, causing his two subordinates to no longer dare to say anything.

Under the pitch black night, Qin Feng tightly gripped a small medicine package in her hands. This poison was concocted by Qin Feng herself and was extremely soluble in water. However, those who drank this water would deplete their physical strength very quickly. As long as they moved, they would be exhausted. They would sweat until their entire body was dehydrated. Qin Feng's movements could be considered nimble, with a few brisk steps, she reached the side of the well.

She opened the medicine bag and poured all the white powder inside into the well. After getting it, Qin Feng was about to leave when she saw the few guards guarding the water source, because the Huns were very lax in managing the water source, so much that a few guards fell asleep. Seeing that the guards were not disturbed, Qin Feng decided to retreat.

"Who is it!?" "Come out quickly!" The guards heard Qin Feng's voice, and quickly surrounded him. Qin Feng saw that the situation was not good, and quickly shot a glance at his two subordinates who were hiding in the corner. The two subordinates noticed and immediately went back to report, but Qin Feng was detained by the Hunters.

Seeing Qin Feng being caught, one of the servants guarding the water source walked up to him and scrutinized him for a moment before sneering: "What are you doing here? You want to poison the well? " As the little general spoke, he stared at Qin Feng with sharp eyes. As long as Qin Feng moved a little, the little general would have seen him. However, Qin Feng was not someone to be trifled with, she said calmly: "That's right, I wanted to poison you, but unfortunately, you caught me before I threw the poison in you. Otherwise, my medicine would have been sufficient for you to drink." When Qin Feng said till here, she even chuckled lightly, with a cold ridicule between her brows.

After the general heard what Qin Feng said, he naturally did not believe it. He carefully examined Qin Feng and said, "Do you think that I would believe your words so easily? Someone, search my body! " Once the general's order was given, several people surrounded Qin Feng, and after searching his body, they found a bag of white powder on him.

"General, I found a packet of poison on this woman's body." The subordinates handed over the white powder to the hands of the general. The general took the white powder and carefully examined it in his hands. He slightly frowned, put it to his nose and sniffed, "Is this the poison you prepared to put in the well?" The general stared at Qin Feng and asked, her expression carrying a trace of suspicion.

Qin Feng smirked and said, "Since you've caught them, it's up to you whether you want to kill them or cut them into pieces." When Qin Feng said this, her eyes showed some determination, but her fearless look caused the little general to be slightly shocked, and the gaze she looked at Qin Feng with was also a little different from before.

"Men, go check this medicine package and get me a bowl of water. Find a doctor and check it. If you have any problems, find me a new water source immediately." The general ordered with a cold voice, his expression a little gloomy as he spoke.

After the general finished speaking, his gaze turned to Qin Feng. He sized him up, and said indifferently: "You are an army doctor, right?" Once the little general finished speaking, Qin Feng frowned and said coldly: "I'm not a military doctor." Qin Feng's words were extremely resolute, causing everyone present to be shocked. But the general that was looking at Qin Feng laughed coldly: "Not an army doctor? "As far as I know, what else can a woman do in a military camp other than be an army doctor?" The general's expression was cold as he said that, he then gave a look to his men, and a few of them went to escort Qin Feng away.

"General, the military doctor checked the drug. It's just a common medicine that can make sweat, and the water in the well doesn't have any poison." His subordinate reported back to the general. The general's expression changed slightly before smiling faintly. "Since this woman can become an army doctor in the enemy camp, it proves that she is not an ordinary person." As soon as he finished speaking, the little general's face revealed traces of a proud smile.

Qin Feng's two subordinates rushed back into the army camp. Upon entering, they knelt down towards Xuanyuan Zhiling, who was pacing back and forth in front of his Grand Commander Camp, while panting heavily and kowtowing repeatedly, "Commander, we deserve to die, we deserve to die. The wangfei, she, the wangfei, she …" The two under Qin Feng cried non-stop as they spoke incoherently and stuttered. After Xuanyuan Zhiling heard this, his face immediately became extremely ugly. He grabbed one of his subordinates' collar and said: "What did you say? Wangfei, what happened to her? Why didn't she come back with you guys?! " When Xuanyuan Zhiling said these words, his eyes carried a trace of killing intent that caused people to feel cold behind their backs.

The two underlings were scared out of their wits, their eyes stared straight at Xuanyuan Zhiling, their legs and stomachs trembling uncontrollably.

"Marshal, we want to go with wangfei, but wangfei definitely doesn't agree. We have to go alone. This one, this one …" His subordinate who was kneeling at the side stammered out. His face was as pale as a piece of white paper. Xuanyuan Zhiling threw the subordinate in his hands onto the ground and cursed coldly, "Why didn't you do your best to protect my wife? You actually have the guts to come back! " Before Xuanyuan Zhiling even finished his sentence, he pulled out the great sword at his waist, wanting to behead the two.

The two subordinates were so scared that they almost peed on their pants. They could only kneel on the ground and tremble while kowtowing to Xuanyuan Zhiling and said, "Marshal, spare me, Marshal, spare me!" At this time, someone from the Grand Commander Camp suddenly requested an audience. When Xuanyuan Zhiling saw that the one who came was Qin Wu, he did not say a word and brandished his sword to kill his two subordinates.

"Marshal, wait a moment. I've heard the news from the spies. Sister has been captured." Just as Qin Wu finished speaking, she saw Xuanyuan Zhiling's sword floating in the air. Maybe others could not understand how he felt, but she thought Qin Wu could.

Xuanyuan Zhiling coldly frowned: "I should have immediately killed these two fools. They were the ones who lost Qin Feng!" As Xuanyuan Zhiling said this, he gnashed his teeth, wishing that he could immediately chop off the heads of the two men. Hearing Xuanyuan Zhiling's words, the two underlings were so scared that they didn't even dare to breathe.

"Marshal, I think it was sister's intention for the two of them to come back. I understand your sister's character, they must have come back because they couldn't convince your sister." Qin Wu said with a sigh.
