It's just that His Majesty is obsessed with taking elixirs, and alchemy is a sensitive matter in Kyoto. It would be inappropriate for Wei Lichu, who loves to tinker with elixirs so much, to stay in the capital.

Liu Yu used the excuse that Wei Lichu was unfamiliar with the mansion and asked Madam Liu to bring Yao Yu and Yu Jiao to help him settle down, and then sent the three away.

Then he said, "Qiu Niang knows that His Majesty likes to take pills, so why did she send Li Chu to the capital?"

"You all know that Li Chu almost lost his life when he was young. Thanks to his Taoist master, Li Chu has been looking for his master all these years. A few days ago, he cracked the geomancy map left by his master, which said that Taoist Zhang is still alive and in the capital. He has already sneaked away once and was stopped by us when he left Liangzhou Prefecture." Liu Zhen sighed, with a hint of worry between his brows. "Qiu Niang discussed with my eldest brother that instead of letting him sneak to the capital and looking for him like a headless fly, it would be better to keep him under your nose so that you can keep an eye on him and prevent him from causing any trouble."

Liu Yu pondered and said, "I have never heard of any Taoist priest named Zhang in the capital. I have seen several Taoist priests who make elixirs for His Majesty in the palace. Among them, the one most favored by His Majesty is Master Sun. He was originally a Taoist doctor and also well versed in Buddhist scriptures. Most of the elixirs that His Majesty has taken in recent years were made by him. This man was found by Master Cheng from Moling for His Majesty."

"It's been so many years, and there has been no news from Taoist Zhang. He must have passed away. But Li Chu has been a perverse child since he was young, and no one can persuade him. Even if we trap him in Liangzhou, there is no guarantee that he will be neglected and unable to be taken care of. We have to find him before we can be satisfied."

Liu Zhen was also well aware of Liu Yu's situation in the capital. Over the years, all the Liu family members had stayed in the border of Liangzhou, thousands of miles away from the capital, and only dared to set foot in the capital during the New Year and other festivals. They were afraid that one day, Liu Yu's act of adopting the orphan of the former crown prince and covering up his identity would be exposed, so that the Liu family would not be ruined and could still keep a glimmer of hope.

Liu Zhen sighed and said, "You still have to go and persuade that child."

"You can't do alchemy in the capital." If the Emperor Mingzheng noticed it, the Liu family would be too conspicuous. Liu Yu said, "If Li Chu wants to stay in the capital to find someone, let him stay. Second brother, go and rest first. I will talk to Li Chu privately about these things."

Liu Zhen nodded, left the flower hall, and followed the servants to the outer courtyard.

Madam Liu, Yu Jiao and Liu Yaoyu were helping to place the luggage brought by Liu Zhen and his companions in the outer courtyard. Wei Lichu brought many wooden boxes filled with bottles and jars, and did not allow the servants to touch them, so he packed everything himself.

When Liu Zhen came over, he saw the servants unloading the things on the last carriage. He smiled and said to Yao Yu and Yu Jiao, "These are the little things I brought you from Liangzhou. You don't have to take them down. Pick out the ones you like and take them back to your room."

Liu Yaoyu was not very interested in the gifts on the carriage, but she wanted to see what was in the bottles and jars in Wei Lichu's box.

However, she still sweetly took Yu Jiao and Liu Zhen to thank them.

Madam Liu asked Liu Zhen if the sisters-in-law in Pingliang Mansion were all well. The two were talking outside. Wei Lichu saw that Liu Yaoyu had been staring at the wooden boxes she had moved into the house. He seemed to have seen through her thoughts, so he generously opened one of the wooden boxes, took out two white porcelain bottles, and gave one to Yu Jiao and Yaoyu respectively.

"Take it and play with it. Consider it my gift to you." Wei Lichu said casually.

Liu Yaoyu shook the bottle, pulled open the red cloth cork, and poured the contents of the bottle into her palm. It was a few round pills. She was surprised and said, "It really is a pill, cousin Li Chu, is this the pill you made?"

Wei Lichu nodded.

Liu Yaoyu picked up the black pill and took a look at it, and said in surprise, "Can this pill really make you immortal?" It is said that Emperor Mingzheng liked to take pills in order to achieve immortality.

But this tiny pill doesn't look anything special.

"It's just to strengthen the body. How can the elixir of immortality be so easy to refine? Even if you have the right time, place and people, there is only a one in ten thousand chance." Wei Lichu said with a smile.

Liu Yaoyu held the pill and tentatively put it to her lips, "I haven't tasted what the pill tastes like yet."

Yu Jiao hurriedly stopped her, "Second sister, most elixirs are poisonous, and the taste is almost the same as pills. If you are curious, I will make you some pills another day."

Yu Jiao didn't believe that the elixir could bring immortality. Elixirs were made of heavy metals and minerals, including chemical ingredients. In history, no emperor who took the elixir had a good end. It had no effect of prolonging life at all.

After hearing this, Wei Lichu looked at Yu Jiao with a half-smile, "Third cousin also knows about elixirs?"

Yu Jiao glanced at him indifferently. Although the poison contained in a pill was very small and it would be fine for ordinary people to take one pill, it was a poisonous substance after all. Wei Lichu, an alchemist, should know the poison even if he didn't know what the chemical substances were. But he just smiled and watched Liu Yaoyu take the pill.

Liu Yaoyu always listened to Yu Jiao in terms of pharmacology. She quickly put the pill in her hand back into the porcelain bottle and said, "Third sister is a female doctor. She is very good at medicine. It's not surprising that she knows about pills."

"So, third cousin knows medicine. What a coincidence. I also know a little bit about medicine." Wei Lichu looked at Yu Jiao with bright eyes and smiled as he moved closer to her. "Here are some medical books left by our master. I don't quite understand them. Can third cousin teach me a thing or two?"
