Time Travel: I am the idle king Li Shen and Li Shimin in the Tang Dynasty

Li Xiu quickly wrote down Li Shen's words, which was also his way of making up for his mistake.

"Cultivation level is not something everyone can achieve like ours. We want to make it possible for ordinary people to have access to affordable medicine."

Many people are blinded by greed and want to make a lot of money.

If we don't restrain them, they will sell these medicines at exorbitant prices, and then how will ordinary people be able to afford them?

Li Shen said earnestly.

"Yes, thank you for your instruction, Your Highness. I know I was wrong." Li Xiuwei humbly accepted the instruction.

He knew that Prince Ji was better than anyone else in this regard.

"Fortunately, your sales period is not long, so we can still make up for it. I will have newspapers in various places pay attention to this matter."

They would also publish the story in the newspapers so that high-ranking officials and dignitaries would know about it.

When you're selling, be sure to ask about their identity; don't sell to them unless they are doctors.

Li Shen thought about it and gave the instructions again.

"Yes, I understand." Li Xiuwei nodded.

"Dr. Sun, how is the donkey-hide gelatin?" Li Shen asked again.

"Your Highness, we only produced more than twenty pieces of donkey-hide gelatin this winter, mainly because we didn't have enough donkeys."

Manager Wang said that he expects to earn significantly more next year.

The owner of the donkey-hide gelatin shop originally priced it at 100 strings of cash, but this time it's only a few thousand strings.

Li Xiuwei also reported.

The year has only just begun; there aren't that many donkeys to begin with.

"Only a few thousand strings of cash is indeed a bit low. Are you saying that one hundred strings of cash for a piece of donkey-hide gelatin is too cheap?"

Upon hearing that only a few thousand strings of cash had been purchased, Li Shen rubbed his chin, deep in thought.

He was hoping to make money from donkey-hide gelatin, but it seems that's not so easy now.

"Your Highness, one hundred strings of cash is already quite a lot. It's just that the price is lower because of the materials used."

Li Xiu quickly explained, fearing that Prince Ji might do something terrible.

One hundred strings of cash for a piece of donkey-hide gelatin is already very expensive. It's also sold outside, and high-quality donkey-hide gelatin can sell for two hundred strings of cash, which is already quite good.

Upon hearing this, Li Shen pondered and realized that he needed to find a way to raise more donkeys.

However, during this period, donkeys were very important production tools. They were hardworking, cheaper than horses, and were an important means of transportation for merchants, especially those traveling to the Western Regions.

There are indeed many donkeys, but few people sell them; they are all useful.

He was wondering whether he should trick a group of people into raising donkeys, just like growing cotton.

I thought about it for a long time but still couldn't find a solution:

"Alright, I'll think about this matter again. Don't rush things about donkey-hide gelatin."

"Since I've arrived today, Physician Sun, please take my pulse."

After Li Shen finished speaking, he stretched out a hand.

"Has Your Highness been working too hard lately?" Sun Simiao took Li Shen's pulse, and after a moment, looked up and asked.

"Yes, there are some. Doctor Sun also knows that I was ordered to go to Xizhou and was busy with official duties, often overworked."

Moreover, the journey back was arduous, involving sleeping in the open and traveling at high speed, which was indeed quite tiring.

Li Shen nodded.

"Yes, the old Taoist priest is writing a prescription for the prince. After returning home, he should take some nourishing medicine and remember not to overexert himself."

Sun Simiao nodded. He knew the situation of Prince Ji perfectly well, but he simply didn't say it aloud.

He picked up a pen and wrote a prescription for Li Shen, then took out several porcelain bottles from the medicine cabinet and handed them to Li Shen.

"Your Highness, these are some new tonics that I, the old Taoist priest, have made. At Your Highness's suggestion, I made them into pills, so there is no need to drink the decoction anymore."

Upon hearing this, Li Shen immediately took it, opened the bottle, and smelled it. The smell was acceptable, not as strong as the medicinal herbs.

"Your Highness, this medicine gently nourishes the essence and replenishes the yin and yang. Take one pill each morning and evening."

The prince is physically weak and lacks yang energy; he can bask in the sun regularly.

Sun Simiao explained the usage of the medicine to Li Shen and gave him a reminder.

Insufficient Yang energy? I've been replenishing my Yang energy by absorbing Yin energy every day, so how can I still be deficient in Yang energy? Could it be that someone has been absorbing it?

"Then how can I replenish my Yang energy as soon as possible? To be honest, Doctor Sun, I brought a maid with me to Xizhou this time, but I still haven't gotten pregnant."

"This matter has troubled me for a long time," Li Shen finally said.

"Your Highness, the old Taoist priest just took your pulse, and your condition is similar to last year. You just need to rest and recuperate, and remember not to overexert yourself."

As for substances that replenish Yang energy, the old Taoist knows that deer antler and deer blood can both replenish Yang energy.

Sun Simiao subtly reminded Li Shen of something.

"Yes, I understand. I will be careful when I get back." Li Shen understood after hearing this.

It's just about replenishing Yang energy, what's so difficult about that?

Li Shen stood up.

"Alright, it's getting late, I must take my leave."

After saying that, Li Shen walked out and returned to Lu's ward.

"My lord, have you finished discussing matters?" Lu Dingniang asked as Li Shen entered.

Li Shen nodded: "Wife, it's getting late, we should go back."

After hearing this, Lu Dingniang stood up:

"Sister, I'll come to visit you another day."

Madam Lu wanted to get up to see her off, but Lu Dingniang politely declined, so she could only bow and see her off.

After Li Shen and Lu Dingniang left, Madam Lu handed the small bag in her hand to a servant:

"Keep it safe, don't lose it."

“Madam, this is so heavy, it must be worth several strings of cash.”

When the servants took it, they immediately noticed that the bag was very heavy, weighing more than ten kilograms.

“It’s more than just a few strings of cash.” Madam Lu shook her head. When she held it in her hand, it didn’t feel like copper coins; they were square and solid.

Curious, the servant opened the bag and analyzed the contents, his face immediately stiffening.

“Madam… here you go.” He handed the bag to Madam Lu.

After taking the bag and glancing at it, Mrs. Lu showed a look of surprise on her face. Then she opened the bag completely and her eyes immediately filled with tears.

"Dingniang is so kind," she murmured, tears streaming down her face.

The bag was full of small gold bars, which, based on their weight, were worth at least a thousand strings of cash.

This was a huge sum of money for their family; Pei Xingjian's salary for ten years might not even amount to a thousand strings of cash.

His younger sister was still as close to him as before.

"Hurry up and put it away, make sure no one sees it." With such a large sum of money, it's inevitable that some people will covet it.

Li Shen originally wanted to visit Songtsen Gampo at the nursing home, but he gave up the idea after bringing Lu Dingniang with him.

Songtsen Gampo lives in a nursing home and is protected by guards from the Prince Ji's residence, so there shouldn't be any problems.

The imperial court is so inconsiderate, actually letting his own guards watch over Songtsen Gampo; they've made him the villain.

Thinking of this, Li Shen felt he should find an opportunity to have a good talk with the Crown Prince. His own guard battalion was not a public institution, so why should he serve the court?

Even if you're doing a favor, shouldn't you at least get some compensation?

The journey was uneventful. Upon returning to the Prince Ji's residence, Li Shen's first act was to send someone to inform Wang Hongfu to come over.

In the study, Li Shen took off his coat and lay down on the rocking chair by the stove to wait.

Soon, Wang Hongfu walked in, panting:

"This humble servant greets Your Highness."

(Please let me know if there are any other issues, so I can address them.)
