The people of Ziyun Dao were fascinated when he heard it, he felt that he had lived in vain for so many years, it turned out that alchemy could still be refined like this, using the body as the furnace and the essence as medicine to refine the real golden pill.

Although what Cao Liang said was unheard of, no one in the world had ever practiced it like this, but the rigor of the theory, the exhaustive method, and there were no inconsistencies, this kind of inner pill method couldn't help but make the people of Ziyun Dao feel excited.

In fact, Cao Liang knew best in his heart that whether it was an outer pill or an inner pill, it was completely impossible to ask for a path of immortality, but the results of the inner pill method and the outer pill method on the human body were very different.

The pills refined by the Wai Dan method are all things that contain heavy metals such as lead and mercury, and if taken for a long time, it is very harmful to the human body. At the end of the Tang Dynasty, six emperors died of erysipelas, which can be described as successive servants and marched forward bravely on the road of death.

After the Tang Dynasty, the Wai Dan Law gradually declined, and it was replaced by Zhong Liquan and Lu Dongbin (yes, it is the second of the legendary Eight Immortals, but there are people in history) who founded the Nei Dan Method. In essence, the inner Dan method is completely different from the outer Dan method, although it also relies on drugs and pills, but it relies more on people's own abilities, and the process of cultivation itself is to explore the potential of the human body and achieve the effect of prolonging life.

Cao Liang didn't hide his selfishness, and taught what he knew.

In his previous life, Cao Liang had a wide range of interests, dabbled a lot, and liked to read some miscellaneous books, but most of them were superficial, had no essence, knew everything, but none of them were proficient.

The people of Ziyun Dao were surprised, they couldn't see that Cao Liang was young, but he had profound attainments in alchemy, especially this kind of inner pill method, which made the people of Ziyun Dao who had been puzzled for many years see the hope of a breakthrough.

In the end, Cao Liang took the formula of Wushi Powder and the two apprentices of the Purple Cloud Dao people, Qingfeng Mingyue, and said goodbye to the mountain.

Qingfeng seemed to be very dissatisfied and didn't want to go down the mountain, and the Ziyun Daoist said to him: "Cao Gongzi is a strange person, he has the ability to seize heaven and earth, and he is old and weak, otherwise he really has the heart to travel with Cao Gongzi to the red dust." The two of you can follow Cao Gongzi is a great opportunity in this life, and cherish it. ”

Qingfeng was helpless, so he had to obey the master's arrangement and followed Cao Liang down the mountain.

Cao Liang did not go back to Luoyang directly, but went straight to the grange, Shouyang Mountain was originally in Yanshi County, not far from Caojia Grange, down the mountain, walked ten miles, and arrived.

Cao Liang also set up the production workshop of Wushisan in the Grange, after all, the Gaoling Marquis Mansion is so big, the processing and production of Wushisan will inevitably produce a large number of toxic and harmful gases, Cao Liang does not want to damage the health of his family, the site in the Grange is wide, and it is convenient to do anything.

Ah Gui had already sent someone to transport the raw materials of Wushisan to the Grange one step earlier, and after Cao Liang returned with the formula and the warlock, he could start work immediately.

The Purple Cloud Daoist said to the two apprentices that there was a great opportunity to follow Cao Liang, Cao Liang listened to it on the side, and couldn't help but laugh secretly, there was a big opportunity for a fart, and he tricked two free warlocks from the Purple Cloud Dao people to let them be coolies, the so-called way of immortality, that was just a ghost coaxing, he had never thought about immortality, how could he teach others the art of immortality.

In the next few days, Cao Liang spent all his time in the Grange except for his rotation in the palace.

With the formula provided by the people of Ziyun Dao, and with the assistance of the two little warlocks of Qingfeng Mingyue, the preparation of Wushisan was extremely smooth, and it only took about ten days for the first batch of Wushisan to be successfully baked.

Compared with the formula on the market, the formula of the Ziyun Dao people is more advanced, and the Ziyun Dao people have added a drug called three-thirds to the five stone powder.

Sansansan, also known as Dasou Mountain Tiger, Mountain Eggplant, Mountain Wild Smoke, because it is very toxic, the raw dose should not exceed 333 yuan, otherwise it will cause poisoning, so this drug is called 333.

The people of Ziyun Dao used three-thirds as a medicine guide, which made the hallucinogenic effect of Wushisan more obvious, and improved the grade of Wushisan as a whole.

Ziyun Dao people can be called a big master in the alchemy world, the five stone powder he prepares, the materials are accurate, the medicinal effect is obvious, compared with the shoddy five stone powder on the market, the toxicity and side effects are small, which is conducive to the long-term use of the drug.

In fact, according to the original, there is not much difference between good Wushi powder and inferior Wushi powder, the most critical thing is the formula ratio, that kind of medicine stone is used more, that kind of medicine stone is used less, that kind of medicine stone is put first, that kind of medicine stone is put later, this is all particular, improper ratio or wrong placement, the toxic side effect is likely to increase exponentially.

There are not a few people who take inferior Wushisan and die on the spot, so those rich celebrities and scholars would rather spend more money to buy Yipinju's Wushisan than dare to buy inferior Wushisan easily.

And now Cao Liang's Wushisan, in terms of quality, is far beyond the Wushisan of Yipinju.

But in terms of popularity, Yipinju's Wushisan has been monopolizing the Luoyang market for many years, with a huge consumer group, word of mouth, and other Wushisan has no competitive strength at all.

The product is available, how to open up the market, this is undoubtedly Cao Liang now urgently need to solve.

The ordinary business model is definitely not good, renting a decent shop in Luoyang City, and the rent is renovated, which is also a lot of expenses, and with Cao Liang's current financial resources, it is impossible to achieve it at all.

Engaging in catapults and crossbows has almost emptied the savings of the Gaoling Marquis Mansion for many years, but fortunately, the raw materials of Wushisan are not expensive, otherwise Cao Liang would have to live in debt.

But now the rental shop Cao Liang can't afford to rent, some of the shops in the corner are cheap, but the practicality is too poor, the location of the shop on Tonghuo Street is good, but it is ridiculously expensive.

And even if the store is opened, why should it compete with Yipinju? Without popularity, it is already extremely difficult to be recognized by those who take medicine, in the initial stage.

However, in his previous life, Cao Liang had done one thing seriously, that is, to do sales, that was his means of making a living, and he had no other skills, if he was engaged in sales, in this era, Cao Liang considered himself second, and absolutely no one dared to admit the first.

Therefore, with quality assured products, Cao Liang is full of confidence, how to quickly sell the products and cover the entire Luoyang market, Cao Liang has already thought of a way.

He didn't go to rent a shop on Luoyang Street, nor did he go to the market to set up a stall, and as soon as he returned to Luoyang City with the finished product, Cao Liang first went to Pei's Mansion to visit Pei Xiu.
