Not long after Tang Zheng entered the study, upstairs, the dog had already changed into a pair of pajamas and walked down. For children over ten years old, the height of the dog is still very good, with a look of almost 11.47 meters. Except that the person is a little thinner. The overall image of the dog is very handsome, and he is indeed a handsome guy.

At this time, Chu Ruyue had already hugged the dog, and said with a chuckle: "Dog, what's wrong?" Don't you know Ruyue's mother after you get better? Just now, I was so sad. Call me Aunt Ruyue, but call me Mother Qin. Do we dogs want to find a baby as a wife? ”

Chu Ruyue, this woman, can really make any joke. Suddenly, an embarrassed look appeared on the dog's face.

Liu Qin smiled and said, "Okay." Is it okay for the dog to take care of the baby sister in the future? ”

Hearing the incomparable seriousness of this county, the dog looked at Liu Qin and nodded, "Mother Qin." I will. No one is allowed to bully a baby. ”

These words, of course, are just a joke. The most important thing is to hope that the dog will not feel strange and can regard himself as his own home.

In the past, when I was demented, it was hard to say anything. After all, I don't understand. But now that he has recovered and he still lives here, if there is no reason, the child will inevitably have some thoughts in his heart. Joking like this dilutes the pressure and burden in his heart, so that he will not feel strange.

Lin Yuqing smiled and said, "Dog, do you know what your name is?" ”

Hearing this, the dog nodded and said, "I know, my name is Zhang Tianhao, but, Aunt Yuqing." You'd better call me a dog. Grandpa barked for ten years, and I think the dog is more kind. ”

Inside the living room. The conversation between the dog and the women, Tang Zheng didn't know. At this moment, Tang Zheng was already sitting in the study.

As soon as he entered the study, Tang Zheng took out the things that the old man had given him when he was dying from the drawer of his desk.

The package was a little sloppy, with a lot of black dirt on it. There is also a faint smell of odor.

When you see this thing, the average person's first thought will never be to open it to see what's inside. Instead, it will be discarded. Tang Zheng is no exception. Ever since I got it, I've put it in the drawer of my desk. Tang Zheng didn't even think about going to see what it was. If it wasn't for the old man who delivered it to himself when he was dying, if it wasn't for what the dog's grandfather Zuihou left behind. Tang Zheng is afraid that he has already lost it.

At this moment, after seeing the magic of the dog, Tang Zheng also had greater expectations for this thing. Layers of packages were opened. Inside, a piece of leather made of unknown knowledge was presented in front of Tang Zheng.

The skin has been a little damaged because of time, and the edges are a little frizzy. The leather has a yellowish-brown color.

Is it a treasure map? Tang Zheng suddenly became a little excited. Aren't all treasure maps made of this kind of skin?

When you open this skin, you can see that the handwriting is already a little blurry. As soon as he saw the first sentence, Tang Zheng was stunned. Zhang Guolao?

Is this the descendant of Zhang Guolao? This piece of information really shocked Tang Zheng. Isn't Zhang Guolao one of the legendary Eight Immortals?

Seeing this, Tang Zheng immediately turned on the computer and typed the three words Zhang Guolao on the search website. As soon as he saw the search, Tang Zheng was also shocked, but he didn't expect that Zhang Guolao was really a real person. There are quite a few things listed above. Some say that he was born in the reign of Yao Shun and was a famous Taoist priest during the Wuzhou and Xuanzong periods of the Tang Dynasty.

Some people say that he was born in the Sui Dynasty. By the time of Xuanzong, he was about a hundred years old, and he had some belief in this Tang Zheng.

Zhang Guo was famous during the Wuzhou and Xuanzong periods. He was received by Wu Zetian and Xuanzong. He was also a well-known alchemist at the time.

There are some historical legends, it is said that Xuanzong also wanted to tell Princess Yuzhen to marry Zhang Guolao. However, he was rejected by Zhang Guolao.

Judging from these things, it is really a person with great ability. Zhang Guolao is the author of "The Immortal Wisdom Elixir Sutra", "Dansha Jue" and other works. is indeed a Taoist priest with real skills.

After reading this series of introductions on the Internet, Tang Zheng's mood finally calmed down a lot, fortunately, from this point of view, at least, Zhang Guolao does have such a person, not a legendary immortal.

The words on the skin are very concise, and the general meaning is in today's words, what is left on it is Zhang Guolao's painstaking research in this life, and the three Dan prescriptions left behind, one is Zhuyan Dan, and the other is Yunlong Dan Zuihou is Yishou Dan.

Below the three Danfangs, there is also a detailed description of the medicinal materials required for the Danfang. The first thing Tang Zheng saw was the Zhuyan Pill, on it, a lot of medicinal materials can be found now, inside, to Tang Zheng's surprise, there was actually a dark grass. Seeing this word, Tang Zheng completely believed it. What does the grass do, this has been verified. The best-selling Flawless on the market is made with the main ingredient of the underworld.

Next is Yunlong Dan, seeing this, Tang Zheng understood that this is a kind of elixir specially made by Zhang Guolao for the royal family, as we all know, the ancient emperor's three palaces and six courtyards and seventy-two concubines, the body is not something that ordinary people can hold, since ancient times, this aphrodisiac medicine is a very popular thing in the palace. It is recorded in history that many emperors died because of the medicine of the dragon and tiger.

There are not many medicinal materials in Yunlongdan, only simple six-flavor medicinal materials. However, judging from the medicinal effects of these herbs, they do have aphrodisiac effects.

Zuihou's Yishou Dan, Tang Zheng took a brief look at it, although he didn't particularly understand. However, the first two Tang Zheng are very sure, so Yishoudan must not be fake.

In ancient times, the average life expectancy of a person was not high. However, people such as Sun Simiao and Zhang Guolao can live to be more than a hundred years old. It's a miracle, it's hard to say, they don't have this real ability to prolong life.

Underneath these pills, the process of refining the pills is also recorded in detail. Among them, the simplest Zhuyan Pill requires 24 days and ten days, which is in line with the number of three sevens. Yunlong Pill takes longer and is more complicated, and the whole step is divided into four steps: nourishing medicine, warming medicine, refining medicine, and Dancheng. Each step is sixteen days, for a total of sixty-four days. This is also in line with the number of I Ching.

Zuihou Yishou Dan is even more terrifying, and there are strict requirements from drug selection and dispensing. The most important thing is that if you want to refine it, it takes nine hundred and eighty-one days of effort.

Although, these elixirs are more magical than the other, and each is more difficult and complex than the other. However, in Tang Zheng's eyes, it was extremely shocking.

The matter of alchemy, Tang Zheng has personally experienced it, the first attempt of the Divine Pesticide Valley, although he has not become a pill. However, those pills also solved Tang Zheng's physical troubles. After that, after getting the Ge Shi Dan Fang, Tang Zheng really began to try alchemy, and adopted a new modern and high-tech alchemy method, although it was a failure in the end. However, this is at least an important step forward, experience is accumulated, and sooner or later it will be successful.

Therefore, Tang Zheng was extremely excited about the three Dan prescriptions recorded above. Each one is capable of having a broad effect. The Zhuyan Pill is too magical, and it can't be seen for the time being. A Zhuyan pill, taken at the age of 20, you can't wait until you are 60 years old to see her, is there any change. This doesn't have much promotion value,

Moreover, Tang Zheng is not ready to promote it, but it is still possible to refine some and let these women of his own take it.

Yunlongdan, this has a broad market space. Don't be able to refine it completely, as long as you can make some medicinal liquids, which contain effective ingredients, this is much stronger than any viagra. Ruihui has relied on this to become the number one pharmaceutical company in Shijie, and once Datang Pharmaceutical launches this, it will be easy to surpass Ruihui.

Zuihou's Yishou Dan, which is even more important. For the elderly, for everyone, the most precious thing is life. Yishou Dan is the most precious.

After looking at the whole leather, Tang Zheng leaned back on the chair at the moment, and the whole person was extremely shocked. At this moment, Tang Zheng's mood was extremely complicated. Originally, Tang Zheng felt that the gift was just a little bit of the old man's heart. Tang Zheng didn't care, but he didn't expect it to be so valuable.

It's like a down-and-out old man giving you an antique, and you look at it and think it's a fake. Then it turned out to be priceless. Tang Zheng is in this mood.

This is a really good person with a good reward. Helping Grandpa Dog and Grandpa Dog is completely improvised. When Tang Zheng made a move, he didn't think of any return at all. However, this return is beyond Tang Zheng's imagination.

At this moment, Tang Zheng had a feeling that he couldn't hold back and couldn't wait to try alchemy. But. Tang Zheng is still sensible after all, and the things are in his own hands. There is no rush at this time. Standing up, solemnly wrapped the piece of leather again, and then put it in a metal box, Tang Zheng walked out, and went directly to the basement and put it in the vault. Keep it safe. Tang Zheng has already made up his mind about this thing, and he can use it himself. However, in the end, when the dog grows up, it still has to be returned to the dog.

After putting the things away and locking the vault, Tang Zheng walked out with confidence. In the living room, looking at the dog and the baby playing, Tang Zheng waved at the dog and said, "Dog, come here." ”

Next to him, Li Fei said with a smile: "Husband, don't call a dog in front of outsiders in the future, call Tianhao, and call the dog Zhang Tianhao." ”

Tang Zheng nodded, seeing Zhang Guolao, Tang Zheng was no longer surprised that the dog's surname was Zhang. At this time, Tang Zheng was a little serious, looked at the dog and said slowly: "Dog, uncle wants to tell you something." Uncle is going to take you as an apprentice and let you join the medical department, are you willing? (To be continued......)
