In room 801 of Mengyuan Hotel, Yuxin was lying quietly on the bed. In last night's car accident, she suffered from a wind chill and had a severe cold.

Fortunately, the condition is not very serious, and it will be fine after a few days of rest.

While Yuxin was recuperating, Liu Xing was preparing to go to Wanxing Mountain.

Wanxing Mountain is only more than 100 kilometers away from Tianjing City, and it only took two hours to drive to reach it smoothly.

Wanxing Mountain is one of the longest mountain ranges in northern China, with steep terrain and extremely difficult to find.

Before coming, Liu Xing had already checked the map, and when Wang Tairan left, he said that his old friend lived at the top of Baicao Peak in Wanxing Mountain.

Baicao Peak is located in the middle of Wanxing Mountain, with an altitude of more than 1,000 meters, and it is said that hundreds of herbs grow in the mountain, hence the name Baicao Peak.

According to the markings on the map, Liu Xing quickly found Baicao Peak.

For ease of movement, he chose to go up the mountain at night.

Baihuafeng is located in the depths of the mountain range, the place is remote, inaccessible, the mountains are full of lush trees and flowers, there are few traces of artificiality, and you can't find the path up the mountain.

Liu Xing could only grope his way up the mountain.

After nearly 2 hours of rapid travel, a faint dim light finally appeared in front of me, and it should have reached the peak.

Picking up his pace, Liu Xing quickly approached the position of the light.

The light shines from a thatched hut in front of which is a small garden with a variety of herbs.

As soon as he approached the thatched house, Liu Xing smelled a strong smell of medicine.

Faintly, you can still hear the sound of conversation in the room.

"There's someone in the house!"

In a flash, Liu Xing gently fell into a corner of the thatched hut and looked into the house through a small window made of tree branches.

There were only two old men in the thatched hut, one lying on a wooden bamboo chair. It was Wang Tairan, and in the opposite corner, another gray-haired old man was guarding a purple alchemy furnace, adding firewood to the furnace.

The alchemy furnace is an octagonal furnace. It is about two inches tall and has a purple color throughout. The surface has a peculiar pattern that resembles an astrolabe, and it is called "Purple Star Furnace".

At this time, a purple flame was burning at the bottom of the Purple Star Furnace, and a white mist came out of the furnace, and a pungent smell of medicine spread through the room.

"Lao Hua, don't waste any more time, your medicine is of no use to me. Wang Tairan, who was lying on the bamboo chair, said in a weak voice, his complexion was a little worse than before. It's a little hard to even speak.

The old man who was refining the medicine was obviously unhappy, and said: "Wang Tairan, you can insult me, but you can't insult my medicine! This 'Yang Shen Pill' of mine is refined from more than a dozen kinds of medicinal materials such as Wuxin Grass, Green Orchid, Bu Ying Ye, and Oolong Root, and it must have curative effects. ”

Wang Tairan smiled faintly and said, "Which of the 'Shuxin Pills', 'Activating Pills', and 'Blood Nourishing Pills' that you refined before was not refined from more than a dozen medicinal materials, and the results are not the same?"

"Refining medicine is like pursuing a woman, how can it be so easy to succeed if you don't try it a few more times?"

"It's as if you know how to chase women, you've lived to be 101 years old. Aren't you single yet?"

"How much better are you than me? You're 98 years old, and you're dying of life, aren't you just the same single?" You don't still have a crush on one of your famous female writers, do you?"

"What's wrong with a crush? It's better than if you don't have a crush!"

"Who says I don't have a relationship?"

"Hmm, which girl are you in love with, let's hear it? It can't be the flower girl in Baihua Village, right?"

"Nonsense, Hua Niu married Chen Ergou from Nantian Village 75 years ago......"

……

The two old men are tearing down and sarcastically mocking each other, and they are like a pair of sworn enemies, pulling out many old things about each other.

After listening to it for a while, Liu Xing learned a lot of information.

It turned out that the old man who was refining medicine was named Hua Yu, and he was 101 years old this year. Hua Yu inherited the northern book king and dreamed of entering the gods. is one of the masters of setting the genre.

It's just that Hua Yu's interest is not in fiction, but in medicine. He applied the idea of setting schools to pharmacy. Trying to design completely new drugs.

For more than 80 years, Hua Yu has lived in seclusion most of the time. Every day, I devote myself to studying the medicinal properties of various herbs, trying to integrate various herbs, and exploring the way of alchemy.

Over the decades, Hua Yu has devised more than 200 new medicines, each of which is made from several herbs, and his medicines are indeed unique.

Wang Tairan could only live for three months at most, but now that more than two months have passed, Wang Tairan is still in good spirits, largely because he has been taking these pills refined by Hua Yu for the past two months.

However, medicine is only medicine after all, not an elixir.

Wang Tairan's physical condition is still worse day by day.

Hua Yu did not give up, and still tried to refine new medicines every day.

Hua Yu and Wang Tairan grew up together, although the two have stubborn personalities and always have some friction between each other, they both regard each other as lifelong friends.

"Lao Hua, after I die, you can bury me in Baicao Peak, at least you can have a companion. ”

"You don't talk nonsense, we haven't distinguished ourselves yet, don't think about it and just leave......"

The two old men were chatting, and at this time, a black shadow flashed out, snapping twice, and the two old men suddenly lost consciousness.

The thatched hut fell silent, except for the soft popping sound of the flame from the Purple Star Furnace.

Liu Xing walked lightly to Wang Tairan's side, first checked his pulse, and then used his true qi to probe the void and reality in his body.

"Alas!"

After a while, Liu Xing sighed helplessly, Wang Tairan's condition was even worse than he imagined.

Wang Tairan does not have any special diseases, and it can even be said that he is not sick at all. It's just that the physiology of his body has aged to the limit, which is the inevitable result of the laws of nature.

Even if people don't get sick, they die of old age.

In a situation like Wang Tairan, unless there are immortals, no one can be cured at all.

It is almost impossible to cure Wang Tairan's illness, and the only way is to delay his aging speed and thus prolong his life.

Liu Xing searched the memory of "Two-Brain Divine Doctor" in his mind and found more than a dozen drugs that can delay human aging. These medicines were all refined from a variety of medicinal herbs, and he was not sure if they existed in Huaxia Kingdom.

With a sweep of his eyes, Liu Xing found that there was a row of bookshelves in the thatched house, and there were many medical books on the shelves, including a "List of Medicinal Herbs of Baicao Peak".

Flipping through the "List of Medicinal Herbs of Baicao Peak", Liu Xing flipped through it.

When he was halfway through, he felt a slight joy in his heart, among the hundreds of herbs in Baicao Mountain, he was just able to refine a pill called "Turtle Breath Pill".

Turtle Breath Pill is an elixir from "Twin Brain Divine Doctor", which can make the human body age about 10 times slower.

Wang Tairan's current physical state is estimated to only live for more than 2 months, and if he takes the Turtle Breath Pill, his aging rate will be slowed down by 10 times, which means that his lifespan can be extended by nearly 10 times, that is, 20 months.

In this way, Wang Tairan can live for a year and a half.

However, after taking the Turtle Breath Pill, Wang Tairan's body's metabolism will also be greatly weakened, and his thinking and activity ability will be greatly reduced, and he will enter a state of semi-sleep.

"Things have come to this point, and that's the only option. ”

Thinking of this, Liu Xing immediately took a piece of paper, wrote down the refining method of the Turtle Breath Pill, the medicinal materials required, the curative effect, etc., and then put the note in a conspicuous position in the thatched house.

He was going to let Hua Yu refine the Turtle Breath Pill.

The refining process of the Turtle Breath Pill is relatively complicated, and ordinary people are simply incompetent, but Hua Yu has decades of experience in refining medicine, and he has no problem at all.

Leaving a note, Liu Xing unlocked the acupoints of the two old men and left in a hurry.

As soon as he left, Wang Tairan and Hua Yu woke up.

Soon, Hua Yu saw the note left by Liu Xing and carefully read the introduction of "Turtle Breath Pill" in the note.

"Turtle Breath Pill?"

After reading the note, Hua Yu's face showed excitement, and the note introduced a method of alchemy that he had never tried, which was based on Hu Qingniu's medical theory and sublimated in "The Divine Doctor of the Two Brains".

"Old man Wang, you may be saved!"

After saying that, Hua Yu hurriedly ran out of the thatched hut, preparing to collect the medicinal materials needed for the Turtle Breath Pill.

……

Five days later, Hua Yu refined the first Turtle Breath Pill.

He first found a rabbit and conducted a clinical trial. After taking a small amount of Turtle Breath Pill, the rabbit soon fell into a state of semi-sleep and slept for two days and two nights.

When the effect of the drug was removed, on the third day, the rabbit woke up again and regained its vitality.

After several trials, Hua Yu was convinced of the efficacy of the Turtle Breath Pill and was ready to let Wang Tairan take it.

"You said that if you eat the Turtle Breath Pill, I will enter a state of semi-sleep?" Wang Tairan was stunned.

"Yes! By then, you'll almost stop aging. Hua Yu explained, "That way, you can live at least another year." ”

Wang Tairan was puzzled: "But, in a state of semi-sleep, I am also unconscious, what is the difference between being alive and dead?"

"It's a big difference. Hua Yu said, "The semi-sleep state can be lifted at any time, and every other month, I can wake you up." With the Turtle Breath Pill, you can extend your lifespan by more than a year. In this year, I may be able to refine a better elixir. ”

Wang Tairan wondered: "This Turtle Breath Pill can slow down the aging rate of people by 10 times, if a person eats Turtle Breath Pill since he was a child, his life span can be 10 times longer, wouldn't he be able to live to nearly 1,000 years old?"

"To be precise, to sleep for 1,000 years. Hua Yu said, "Theoretically, as long as there are enough Turtle Breath Pills, people may indeed survive for 1,000 years." However, the refining of this Turtle Breath Pill was extremely complex, and the herbs required were extremely limited. The herbs of the entire Baicao Peak are estimated to only be able to refine a maximum of 10 Turtle Breath Pills. ”

Wang Tairan asked: "The Turtle Breath Pill is so magical, it is simply a miracle medicine, who left that note?"

"I don't know, maybe it's a master of the world! Maybe it's a miracle doctor who has lived for hundreds of years. ”
