Wei Lichu narrowed his eyes, as if he didn't expect that she actually thought of Cheng Ying like this in her heart.

He paused before saying, "It's good that my third cousin can see it so clearly. Traitors will never have a good ending."

Yu Jiao nodded, agreeing deeply that in history, most of the powerful and corrupt eunuchs had a bad ending.

Not long after, Bai Lu came back. Jian Jia brought the medicine she brought back to her. Yu Jiao asked Wei Lichu to take it. Wei Lichu drank it all in one gulp. After finishing, he held the empty bowl and asked, "What medicine is this?"

"It has the effect of relieving pain, so that you won't faint from the pain when getting the stitches later." Yu Jiao answered.

When the medicine took effect and Yu Jiao was cleaning Wei Lichu's wound, Wei Lichu's eyes widened in surprise, "This is the effect of this medicine!" He hardly felt any pain, and the wound that had been extremely uncomfortable was no longer painful.

Yu Jiao smiled gently, and her hands moved neatly and skillfully. After cleaning the wound, she cleaned and disinfected it, then asked Li Jing to thread the catgut with a horn needle and hand it to her, and she skillfully sutured the wound.

Wei Lichu stared at his shoulder without blinking, and felt that Yu Jiao mended the wound just like a woman sewing clothes. It was both amazing and a little scary. After all, not everyone could use human skin as cloth to mend, and Yu Jiao seemed to have sewn it thousands of times and was extremely skilled.

Yu Jiao cut the catgut, applied tissue-growing ointment and sprinkled azurite powder on the sutured wound before bandaging it carefully.

Then, while cleaning up the used equipment, he reminded Wei Lichu about some foods to avoid.

Wei Lichu gathered his clothes around his shoulders and closed his collar, seeming to be a little slow to react, "Is this all right?"

Yu Jiao smiled, "Why? You still want stitches?"

Wei Lichu naturally didn't mean that. He asked, "Don't you need to drink the medicine?"

"Your wound is on the surface of the body, so taking medicine internally won't have much effect." The human body needs a growth process to heal itself, and taking medicine internally for a knife wound can only strengthen the body, replenish qi and blood, and has little effect on wound healing.

Yu Jiao joked with him again, "The elixirs you made are miraculous. Instead of taking other medicines, you might as well take a few of the elixirs you made!"

Wei Lichu smiled helplessly, "You know that the elixir contains poison. I usually sell the ones I refine to others."

Is this hurting others but not yourself? Yu Jiao didn't know what to say to him, and after a while she said, "I don't think your family is short of money..."

Wei Lichu naturally didn't make pills for money, he wanted to save people.

Thinking of this, the smile on Wei Lichu's face faded. Cui Mubai promised him that he would lead away the East Factory lackeys guarding the Nian Qu Tower, but he had to wait a few days after Cheng Ying left Beijing.

He glanced at Yu Jiao and asked casually, "I heard that Master Cheng will be leaving Beijing for a while? Third cousin, do you know what he is going to do?"

Yu Jiao shook her head. She seemed to have mentioned before that she would be leaving the capital for a while. "She said she was going to do some work for the emperor."

Working for the Emperor? Wei Lichu guessed in his heart that the most important matter that made Cheng Ying leave the palace was to supervise the construction of the Taihe Palace in Xianyang.

"Do you know when he left Beijing?"

Yu Jiao wiped the scalpel clean and glanced at Wei Lichu. "I don't know. Why are you asking about this?" She couldn't help but think of the time when Wei Lichu was hunted down by the East Factory some time ago. He had evaded her by saying that it was because he secretly went to the market to sell elixirs. Now Yu Jiao thought about it and realized that she had found a flaw. Emperor Mingzheng liked to take elixirs, and there was a trend among the people to follow suit. If it was just a trivial matter like selling elixirs, why would Cheng Ying be bothered to arrest him personally?

"Cousin Li Chu, have you done anything in private that you shouldn't have done?" Yu Jiao asked him suspiciously.
