Chapter 1427

The old master and the old mistress had their own family health doctors. However, since Zhu Yanyi was a little divine doctor, the doctors stayed silent when she took their pulses.

"I am fine. It is just the changing season, so I cough a bit. You are making a big fuss," the old mistress said. But her heart was sweeter than honey.

Zhu Yanyi had a good personality and great medical skills. The old mistress always felt that she suffered by marrying Yan Aohan. Her fourth son must have accumulated great virtue in a past life to find such a good wife.

Zhu Yanyi smiled and looked at the old mistress’s prescription. She said nothing but taught Aunt Liu a few seasonal medicinal recipes. Then she handed a pot of monkey wine to the old master.

"Dad, I got this monkey wine a while ago. Please taste it. But do not drink too much. Although it is good, you should only drink one or two cups per meal."

The old master heard it was monkey wine. He took it, opened it, and smelled it. "Good wine! Yanyi, does your father have any?"

The old master was not ignorant. If she had some, she naturally wanted her daughter-in-law to remember her natal family.

"Yes," Zhu Yanyi smiled. "I saved a pot for my father. I also gave one pot each to Grandpa Chun and the other masters. I prepared them long ago."

"That is good." The old master knew this monkey wine was rare. Since Zhu Yanyi could provide so much, it was no small feat. Therefore, she did not demand more quantity.

In the past, the old master worried about nothing except Yan Aohan’s marriage. Since Yan Aohan and Zhu Yanyi got engaged, he had no worries. With such a good daughter-in-law, he was fully satisfied.

"Has there been any news from Fourth Son recently?" the old master asked Zhu Yanyi.

Zhu Yanyi smiled. "She called the day before yesterday. She said things there are going smoothly. If there are no problems, she will return in at most a week."

"That is good." The old master nodded. He knew his son’s ability was extraordinary. But he did not ask how extraordinary. At his age, the most valuable thing was to be wisely ignorant. It was better to be vague about some things than to know everything.

After accompanying the old master and old mistress for lunch, Zhu Yanyi took her leave.

Zhu Yanyi got into the car and looked at Luo Gang, who was driving. "Brother Luo, teach me to drive when you have time. I think I should learn to drive myself."

Actually, she could drive. She learned it in her previous life. However, she usually drove slowly. Her relatives and friends in her previous life only felt that sleeping in her car was very comfortable.

Because she drove slowly and steadily, it was very safe. Passengers did not need to worry about danger, so they could sleep peacefully.

"Miss, let Master Yan teach you personally when he returns," Luo Gang said with a smile.

Zhu Yanyi glanced at Luo Gang. "Brother Luo, I find your eloquence has improved a lot over the years."

"I learned it from you and Master Yan," Luo Gang chuckled.

Zhu Yanyi was speechless. Then she said, "I will tell Aohan to let you teach me. See if you still refuse."

Luo Gang chuckled. "Miss, even if you tell Master Yan, he will absolutely not let me teach you. He will definitely teach you personally." Over the years, Luo Gang had experienced Master Yan’s jealousy firsthand.

Zhu Yanyi smiled slightly. Well, it was indeed like that. It seemed she could only learn driving from Yan Aohan.

Actually, Zhu Yanyi did not need to learn driving urgently. The car Yan Aohan ordered for her had not arrived yet. By the time the car arrived, Yan Aohan should have returned.

Next, Zhu Yanyi went to visit Grandpa Chun and the others. She gave them monkey wine without disturbing anyone. She also visited Zhu Shun Yao.

Zhu Yanyi had plenty of monkey wine, so she left a pot for Taishu Yuanxiang as well. She asked Zhu Shun Yao to notify Taishu Yuanxiang to pick it up.

In the following days, Zhu Yanyi entered the laboratory again.

Looking at the pile of herbs, Zhu Yanyi felt she had hit a strange bottleneck. Once she broke through this bottleneck, her drug-making level would rise to a new tier.

The herbs were fine, and the dosage was correct. But problems always occurred during production. Zhu Yanyi felt she had overlooked something. She decided to start from the beginning.

First, she checked the herbs to confirm the ratio. Then she began extracting the essence. Looking at the essence in the test tube, Zhu Yanyi started blending the essences.

Any drug must first blend the essences. Only after blending the essences could it be considered successful.

She carefully controlled the dosage during blending. The dosage was correct, and the reagent seemed to blend well. That meant making the powder.

Wait, powder? Zhu Yanyi paused slightly. She looked at the reagent and thought about the prescription. She realized her mistake. Why did she insist on making powder? Since the reagent was successful, why turn the liquid into powder?

So her oversight was here.

She subconsciously believed that drugs improving constitution must be powder or pills. Actually, they could also be reagents. She finally understood where she went wrong. She took a deep breath. Fortunately, she found it now.

Reagents were also a form of drug body, just existing as liquid.

Recalling content from the third and fourth civilizations, drugs that changed or enhanced human constitution existed as reagents in those civilizations. It showed that reagents were a very common type of drug. She could also follow ancient methods to package the successful reagent. Only the test tubes needed to be specially made.

Zhu Yanyi tested the made reagent. After several days of testing, the success rate was very high. Now, human trials were needed, but that required the right timing. For now, the experiment could be considered concluded.

Zhu Yanyi checked her memo. She needed to rest well, then go to Kyoto Hospital on Monday. After the hospital, she would go to customize a batch of special reagent tubes.

After washing up, Zhu Yanyi lay on the bed and fell asleep slowly.

When Yan Aohan appeared, he saw Zhu Yanyi sleeping. He smiled, then washed up and crawled into the warm quilt. He hugged his lover and closed his eyes to sleep.

Familiar scent let Zhu Yanyi know Yan Aohan had returned without opening her eyes. She just adjusted her posture slightly and continued sleeping in Yan Aohan’s arms.
