The plan for printing books is quite full, and after the "Tea Classic" is "Elementary Arithmetic". After the introduction of Arabic numerals, it is more convenient to calculate and the learning speed can be accelerated.

"Xu Cheng--" Wen Ren carefully reported: "The available funds in Dayingku are no longer enough. Are you cutting down on unimportant work?"

It is the stage of laying the foundation and gradually spreading out that the initial investment in building workshops, building dormitories, etc. must be very large, so Xu Qilin naturally knows it. However, it is obviously too late to continue to invest after seeing the benefits.

"I have reported to Your Majesty that I will add another 20,000 yuan to Dayingku." Xu Qilin smiled and said casually: "There should be a reply soon, and there will be no shortage of money at that time."

After pausing for a moment, Xu Qilin said again: "Even if Your Majesty hesitates and refuses to approve it, there will be no problem with adding additional investment when the sugar is made."

Wen Ren bowed and said yes, but he had fulfilled his obligation to remind him anyway. When he really had no money, he couldn't blame him.

Moreover, His Majesty Li Er has already divided the shops outside Jinguang Gate and Chunli Gate into Dayingku. More than 100 stores are rented out, and it is also a lot of money.

If it weren't for too much or too big, Dayingku would have made a profit. However, Xu Qilin was obviously not so short-sighted. Behind the profits, he still had plans that others didn't know.

Moreover, although His Majesty Li Er has the intention to enrich the inner palace, he is not very anxious. Anyway, the current treasury is also owned by his Li family, so he can spend it at will.

"Brother is really busy." Yuchi Huan finally found Kong'er and followed Xu Qilin to the office.

Xu Qilin smiled and said, "It was also a while. Brothers came here unfortunately today, but they were negligent."

Yuchi Huan waved his hand quickly and said, "Brother is capable, and he is not as good as us useless people."

Xu Qilin said a few humbly and asked with a little guilty conscience: "Brother, come here today, aren't you looking for someone to play?"

Yuchi Huan explained his purpose, which made Xu Qilin hesitate. Could it be that the old door god is used to it and wants to ask himself to go over and teach him a lesson?

Yuchi Huan didn't know what Xu Qilin was thinking, and he said to himself: "My father didn't know what Taoist priest said, and he believed in refining alchemy and taking medicine. Hearing that his brother's master was a master of Taoism, he thought about what method he had and asked his brother to go and ask."

Xu Qilin blinked his eyes and thought to himself: This is another person who is dying. The sashimi is discouraged. What other pills are there? It is mercury, arsenic, and other heavy metals. Is it because of the slow death?

He was scratching his head here, but Yuchi Huan was looking forward to it persistently, and he couldn't even think about it.

During the Sui and Tang Dynasties, with the improvement of Taoism's status, the trend of refining and taking medicine was popular. However, the disadvantages of taking elixirs became increasingly prominent. As more people died, the voices of questioning and opposing taking elixirs naturally grew.

"This—" Xu Qilin scratched his head again and asked, "I wonder what kind of elixir Duke of E is taking, do you think it is effective?"

Yuchi Huan said: "My father took Baiyunying powder every morning, which is a secret recipe taught by a fairy."

Xu Qilin pretended to hold his forehead and thought, summoning the soul to the upper body. What about Bai Yunying? I don’t know what it is, so I should ask a famous doctor!

Baiyunying is a kind of Chinese medicine, a kind of mild toxicity. Later generations were famous for industrial materials and were widely used in coatings, paints, electrical insulation and other industries.

The old door god's body shape is really great. He can live to seventy-four after eating these industrial materials every day. I admire him, awesome!

Xu Qilin was very distressed. How could he explain to the old door god so that he could understand and listen in?

If you say it is poisonous and it is not good for your health, then do you believe it?

Even the Taoist classic "Xuanjie Lu" says: "There are often used for the incision and transformation medicines to eliminate ulcers, and they form poison together. There is no sign of immortality when the golden sand enters the five internal organs, which is very wrong. People in the world do not know that there are immortal people who have taken the previous ones."

But from the Tang Dynasty to the Ming Dynasty, not to mention that there were several emperors who died because of taking pills. It is said that His Majesty Li Er also passed away because of this, which shows how tempting the thought of immortality is to people.

After thinking about it, Xu Qilin's eyes lit up and he came up with an idea. Don't you like taking pills? I can't persuade you, so I'll give you some good things for your body, also called pills, which are big, and you can enjoy it.

"As for this elixir, my family master has passed on two types of medicine." Xu Qilin said in a deep thought: "It's just that someone is strong and young, so there is no need for this external elixir to replenish it."

"Oh, oh!" Yuchi Huan nodded repeatedly, feeling happy, but still echoed Xu Qilin, "We are fierce and fierce, so of course we don't need to take any pills."

The dragon spirit is fierce? Is it a bit of improper use of words? If you want to take my medicine, the dragon spirit is fierce, and the dragon spirit is fierce.

Xu Qilin coughed dryly and said, "In this way, you go back and tell the Duke that it will take several days to make this pill. After it is prepared, you will go to serve the Duke in person."

"How many days are there?" Yuchi Huan said with a hint after asking: "It's not that my brother urging me to me, but my father is really impatient and has no accurate letters, so he must scold me."

Xu Qilin thought for a while and said, "I will definitely visit the Duke in three days."

"Okay, okay." Yuchi Huan repeatedly claimed that it was good, thinking that this was done well, and there was really a elixir for his father.

Xu Qilin sent Yuchi Huan away, returned to the room to calm down, summoned the soul, began to write prescriptions, and tinker with his Dali Pills.

…………………

In ancient times, there were famous doctors such as Bian Que, Hua Tuo, Zhang Zhongjing, Sun Simiao, Li Shizhen, and Lu Tianshi. What are the medical saints, medicine saints, medicine kings, and the most important time they were also miraculous doctors. In modern times, there were no doctors as famous as doctors.

Does that mean that the older the doctors are, the more powerful they were at that time?

Xu Qilin felt that he could not understand this way. The so-called progress was naturally improved based on the predecessors. The same is true for traditional Chinese medicine. The older the age, the less prescriptions, and the understanding of certain diseases is not comprehensive.

Like science, the more you can learn and learn from traditional Chinese medicine, the more prescriptions and experience you can learn and learn from, the more advanced medical skills and the diagnosis should be more accurate.

Therefore, when Xu Qilin asked his soul to go up, he chose Ye Tianshi, the genius doctor who was the last known era. But he only made two pills, which was really useless. I'm sorry, Doctor Ye.

One pill was named Xiaoyao Dan by Xu Qilin, which is Liuwei Dihuang Pill, which has been dedicated to thousands of years of life; the other pill is Fugui Dihuang Pill, which is named Huichun Pill.

It's a very vulgar name, but it is indeed much stronger than the elixirs refined by Taoism. One is to nourish the kidney yin and the other is to nourish the kidney yang. If you can't eat this, just eat that, there will always be one suitable for you.

The medicinal materials are made into powder, the honey balls are cooked, and the wax oil is boiled to make medicinal shells. These are naturally not the work Xu Qilin does.

So, a small workshop came into being again, and more than a dozen honest and hygienic servants in the Yeting Court became female workers in the pharmaceutical factory.

At the same time, Xu Qilin also added a new product to his store. It is a kidney-tonifying thing. Ancient people who have wives and concubines need it the most! The dragon spirit and tiger are fierce, which is what men have hoped for for thousands of years.

Write down the symptoms of kidney yang deficiency and kidney yin deficiency, and Xu Qilin asked the craftsmen to print it out. If someone takes medicine, you must give an explanation! If a man regains his strength, this pill must be sold at a high price, right?!

Xu Qilin thought about the plan to make a fortune, took two boxes of pills and a few bottles of high-altitude wine. After thinking about it, he felt shabby, so he ordered Zuixiaolou to prepare ten dishes and deliver them to Duke E's mansion in a food box.

He was not too slow, and the Yuchi Sect God was already anxious. Three days were not long, but the old Sect God was waiting to try the effect of the elixir of the world!

"Three days, I promised that I have to wait until night?" Yuchi's door god stared at Yuchi Huan with his eyes slanted, and began to vent his dissatisfaction.

Yuchi Huan hurriedly explained and defended: "My father, it's not yet noon, please wait a moment. Otherwise, I'll greet him again?"

Yuchi's Sect God snorted and said, "Stay honestly, and urge you again, it's not embarrassing enough."

Yuchi Huan laughed twice and said, "Then I'll go to the mansion and wait. As soon as Qi Lin arrives, I'll bring him here."

Seeing that his father didn't say anything, Yuchi Huan quickly slipped away to avoid his father being upset and scolding him.

It was almost noon, and Xu Qilin and Zuixiaolou came to Duke E's mansion and were immediately greeted by Yuchi Huan, who was waiting for sight.

Yuchi Huan led Xu Qilin away and said with relief: "If my brother doesn't come, I have to stay in the doorman and dare not see the master."

"It's been three days!" Xu Qilin laughed and said, "For the first time I visited the Duke, I always have to clean up to show respect, right?"

"Sir, don't talk about false etiquette, brother doesn't have to be so serious." Yuchi Huan led Xu Qilin to the hall. When he saw his father, he immediately introduced him, "Sir, Brother Qilin comes to pay a visit."

Xu Qilin hurried forward to salute, "Xu Qilin has met the Duke."

"No, no, no." Yuchi's door god smiled on his black face and reached out to signal, "No need to be polite, sit down quickly."

After Xu Qilin thanked him, he presented gifts and explained them one by one.

"This is the pill made by the secret recipe passed down by the teacher. It has the effect of strengthening the body!" Xu Qilin opened two wooden boxes and the packaging was quite particular. There were red marks on the wax balls "Xiaoyao Pills" and "Zhuangli Pills".

Yuchi's Gate God's eyes were wide open. Just looking at the packaging was not an ordinary thing. He asked quickly: "It's just to strengthen the body, but there are other effects?"

Xu Qilin smiled helplessly and said, "I don't know what the Duke said, but I can become an immortal? If so, I will only let the Duke down."

After pausing for a moment, looking at the slightly disappointed expression of Yuchi's Sect God, Xu Qilin continued: "The master said: Refining alchemy to seek immortality was from the Emperor of Qin, and the alchemists during the Wu Dynasty of the Han Dynasty. Who knew that flesh and blood, water and valleys, could it be that something that fell heavily in the stomach and intestines for a long time? It is foolish to die after pursuing life."

The God of Yuchi frowned and said, "It seems that Master is practicing internal alchemy, and he may not know everything about external alchemy."

Internal alchemy should be the name of qigong by Taoists and Taoists. It mainly uses the human body as an alchemy furnace, which absorbs external qi, nourishes internal qi, harmonizes yin and yang, and unblocks meridians, and implements it with "refining essence into qi, refining qi into spirit, refining spirit into emptiness".

Xu Qilin does not object to this. Cultivating one's own character is also a kind of exercise, at least it does not harm the body. Moreover, correct breathing is indeed beneficial to the body and mind.

As for external alchemy, Xu Qilin felt that it was possible to produce some chemical agents in the messy reaction process, but this possibility should never be overestimated.

Toxic means toxic. Mercury, lead, arsenic, and other heavy metals accumulate in the body. The only consequence of "seeking immortality and death quickly."

Xu Qilin smiled faintly and said, "Masters may not practice the external elixir. However, the government knows that someone who practices external elixirs and becomes an immortal? My master is over 70 years old. Although his hair is white, he is as healthy as a young man. He is better than a young man when he travels to climb mountains. This is something he can see with his own eyes."

"This—" Yuchi's Sect God was a little confused. After all, the gods were just legends, so how could they see them with their own eyes?

Seeing that the adult was embarrassed, Yuchi Huan hurriedly interrupted: "Qi Lin bought the food and drinks. Adults, it's better to sit down and eat while talking."

Yuchi Sect God nodded and said, "Qi Lin is intent."

Yuchi Huan greeted the servants and placed tables and chairs in the hall to serve wine and food.

Xu Qilin and Yuchi Huan sat down with the Prime Minister, poured the high wine they brought to Yuchi's door god first, and said with a smile: "The teacher is good at wine, so I will study it and make this strong wine, and ask the Duke to taste it."

Before the Yuchi Gate God had served the glass, he smelled the wine and couldn't help but smile and said, "The wine smells so good, and you will know it's not bad before you can. Master Qi Lin, you should follow it."

Seeing the adult's eyes coming, Yuchi Huan nodded quickly, "Don't worry, sir, the child must respect his teacher."

Yuchi's door god said "um" and then took a sip of the glass. His eyes suddenly narrowed and he said, "What a spicy wine!"

Xu Qilin hurriedly said, "My teacher often goes to the mountains to collect herbs and practice Taoism. The mountain wind is cold, so the boy makes this strong wine to warm him up."

Yuchi's door god nodded, his eyes showed appreciation, he drank all the wine, exhaled a sip of wine, and praised, "Good wine, strong enough, is in line with the taste of a coarse person."

"Heroes ride horses, heroes drink strong wine." Xu Qilin smiled and said, "This wine is spicy, and those who do not have a large alcohol capacity dare not drink too much."

"When it comes to alcohol, someone boasted that he was the second most, but no one dared to be the first." Yuchi's Sect God stroked his beard and looked proud.

Yuchi Huan immediately stood up, snatched the bottle of wine from Xu Qilin, poured a glass for the adults, and filled it with him.

"This dish tastes good too." Yuchi's Gate God first brought two chopsticks to braised mutton, and praised while chewing: "It's much better than the chef in the mansion."

Yuchi Huan laughed and said, "Brother Qi Lin opened a restaurant called Zuixiao. The child has eaten there a few times, and even eating the dishes at home can't get enough of it."

Xu Qilin said: "If the Duke likes to eat, he will let the chef go to Zuixiaolou to study. The boy's desire for verbalism is also because of his family's preference."

"Whether there are no food taboos for those who practice Taoism?" Yuchi asked in confusion.
