Zhao Xun found a page in "Alchemy Experience", which introduced a legendary elixir that can cure all poisons, called Nirvana Pill.

Elder Sun instructed beside him that he had not refined this elixir, but he had already proved in law that this elixir could be refined and should exist. Moreover, this elixir can not only remove all poisons, but also allow people to enter a state that can live forever and become one with heaven and earth.

Eternal life, one with heaven and earth.

Zhao Xun looked at this sentence, his heart was full of imagination, he didn't know what this state was like, but he had awe of heaven and earth in his heart. Heaven and earth are the producers of spiritual power, and if they are integrated with heaven and earth, does that mean that people can have endless spiritual power?

As long as a person has ruthless and endless spiritual power, he can exert any kind of trick, such as Zhao Xun's beginner "Heavenly Star Go", summoning three meteorites out, he can play an infinite number of times, maybe he can directly cultivate to the highest level and get the high-level "Heavenly Star Go", in this way, let alone dealing with a certain enemy, even if he destroys the whole world, Zhao Xun can do it.

Of course, such a powerful elixir is definitely not so easy to refine.

Elder Sun also explained below that this kind of pill is different from ordinary pills, and it is hundreds of millions of times more difficult to refine than ordinary pills, and even the ancestor of the Dan Dao back then, Batu, did not refine this.

According to legend, the inventor of this Dan recipe is Ba Qing, the ancestor of Dan Dao, but after Ba Qing's death, even his descendants did not refine this pill. It is equivalent to saying that in this world, except for the Dan Dao Ancestor, there is no second person who can refine the Nirvana Pill.

Zhao Xun looked at it and couldn't help frowning.

Even the descendants of the ancestors of the Dan Dao couldn't practice this elixir, how could he refine this elixir. He didn't even know a little bit of alchemy knowledge, and he had never practiced alchemy, so how could he refine this legendary thing as soon as he came up.

Let's talk about a practical question, Zhao Xun doesn't have an alchemy furnace, how can he do alchemy?

Finally, there is an important question, and that is the material for alchemy.

Zhao Xun then looked down, and after reading it, his heart was even more hesitant, and there was a very simple line written on it: refining this Dan, you must not forget, the supreme truth of yin and yang, the other is the same, the thing that is yin, the thing that is yang, the balance is the same, and you can become a pill.

Yin and Yang Balance?

The beads of sweat on Zhao Xun's head were directly big, the most common truth in this world is yin and yang, and the most difficult truth to understand is also yin and yang, how many people claim to balance yin and yang, and finally die, the truth in this is deep, Zhao Xun used to be very interested in the way of yin and yang, but if you want to understand the things inside, it is not something that can be understood in one or two decades, at least one or two hundred years.

In this way, it would delay Zhao Xun's cultivation, so in the end, Zhao Xun chose to work hard to cultivate, increase his lifespan, and then study this mysterious thing.

But he didn't expect that in the blink of an eye, the biggest problem of yin and yang was placed in front of Zhao Xun, and if the yin and yang were balanced, Zhao Xun would be able to live, otherwise Zhao Xun would only have a dead end.

Zhao Xun looked at the books, his brows furrowed tightly.

In any case, there is not much time left for him, and if he wants to survive, he must find the antidote in a maximum of five days.

Five days to balance yin and yang?

Is this really possible?

In fact, there is no problem with the things that this Nirvana Pill will use, Zhao Xun has the things of the Zhiyang, the meat of the boundless hydra, and the things of the Zhiyang are also easy to find, after all, the place where Zhao Xun is located is the desolate forest with the most spirit beasts and elixirs.

As for the Dan furnace, Zhao Xun remembered some people who had burned it before, and he collected other storage rings, and in one of the storage rings, Zhao Xun saw the Dan furnace.

Zhao Xun gritted his teeth, closed the book, and said to the demon king squirrel and the little bear next to him, "Are you two willing to help me?"

The Demon King Squirrel nodded, and Chi Chi's dark eyes stared at Zhao Xun.

"Well, you go and help me find some of the most yang things, the more the better. Zhao Xun waved his hand and assigned tasks to the two small things.

The Demon King Squirrel's eyes rolled, as if he was thinking about where he had seen such a thing, and then he led the bear out of the cave.

Zhao Xun was looking for those Dan furnaces in one storage ring after another, and in the end he found more than one Dan furnace in total, more than thirty. In fact, there are not many people with Dan furnaces on their bodies, which can also be seen from another aspect, how many people Zhao Xun has killed.

After a while, the bear cub returned and found a pair of scaly deer antler velvets.

Zhao Xun touched its head, took a Dan furnace, and added some trivial spirit grass to prevent the two things from being too strong and exploding, and then put the scaly deer antler velvet into the Dan furnace first, and then began to use the spiritual fire to start calcining.

Because of his inexperience, when Zhao Xun was calcining, he was honestly afraid, always afraid that he would give less things and more things, and finally let the Dan furnace explode, but during the calcination, Zhao Xun had been following Elder Sun's "Alchemy Experience", and he didn't dare to make a mistake, and in the end there was still a little effect, and soon after, the fragrance of the pill slowly came out of the entire cave.

Half an hour later, the things of the most yang are half burned, and it is time to add the things of the yin.

Zhao Xun cautiously put a piece of the meat of the boundless hydra in, this put it in, the effect was surprisingly good, without the slightest violent reaction, in the whole cave, the faint Dan fragrance came out, more fragrant than the taste just now, this is the same as the alchemy book, as long as it can be Dancheng, the taste is the same fragrance as the earth and plants.

Moreover, what made Zhao Xun even happier was that there was a trace of misty gas around the Dan furnace, colorful, fluttering, and it looked very beautiful, this is all the image of Dancheng, I believe that it will not be long before Zhao Xun will refine this pill.

Zhao Xun was originally very happy, thinking in his heart that this legendary elixir was so easy to practice, and he really had the talent for alchemy.

But when he thought about it, he felt that this was the way it should be.

What are his materials, the Borderless Hydra, who can easily get it, it's impossible, even those super auction houses in the capital will not easily get the Borderless Hydra, this kind of priceless thing, and the spirit grass that Zhao Xun used to neutralize it is all rare and precious plants.

In addition, the thing of the sun, the deer antler with scales, although Zhao Xun didn't know where the bear got it, but this deer antler with scales had not been seen before, it must be a very special item, rare is expensive, and Little Bear Chichi made a great contribution this time.

Seeing that Zhao Xun's eyes were extremely gentle when he looked at him, the little bear was also very happy, and the two big bear paws stretched out directly and hugged Zhao Xun's thighs.

"Bump!"

Suddenly, a loud noise came from Zhao Xun's simple workbench, and it actually exploded!

Zhao Xun's whole face was already black, and Xiao Xiong fortunately hugged Zhao Xun's thigh, otherwise he would have been affected.

"Poof!"

Zhao Xun exhaled a puff of black smoke, touched his eyes, and finally had to admit that he had failed this time.

It doesn't matter if you fail, anyway, it's the first time, Zhao Xun has enough self-confidence, and he will be able to make that pill the second time, after all, the effect of the first time is so good, it is very close to Cheng Dan.

Seeing that Zhao Xun had exhausted the materials, Xiao Xiong ran out again to find something for Zhao.

The Demon King Squirrel came in at this time, came in with a large pile of things, and slowly piled them on top of Zhao Xun's stone table.

There are the tongue of the flame beast, the duck paw of the bursting duck, the big teeth of a saber-toothed tiger, the true yuan fruit, and the tentacles of the sea salt beast, etc., in short, there are a lot of them, it looks like a dazzling array of things, Zhao Xun feels wasteful when he looks at these things, and says in his heart: "If I refine the elixir, there may be more than half of these things left, then all the remaining things are stuffed into the bear's mouth, and it can eat it." ”

For the first time in alchemy, Zhao Xun destroyed a Dan furnace, but fortunately there were many Dan furnaces.

Zhao Xun chose one of the best quality, the whole body is pitch black color, like black charcoal, slightly cool to the touch, although Zhao Xun can't tell what is valuable, but as soon as this Dan furnace is held in his hand, he immediately feels very extraordinary, he knows that this must be a good thing.

The second time in alchemy, he learned the lesson just now, by the way, the lesson he just got was that he didn't do anything wrong, the heat may not be right, so he held his breath and put the materials in successively, this time, he chose the teeth of the saber-toothed tiger, there was no problem.

Then put the Borderless Hydra.

"Bump!"

As soon as it was put in, the Dan furnace immediately exploded, and there was no room for negotiation at all.

Zhao Xun couldn't accept the result for a while, this was no different from the operation just now, and he was definitely more skilled than just now, but how could he blow up the Dan furnace so quickly?

Zhao Xun came for the third time.

Bump, bump, bump......

The first day passed, and Zhao Xun destroyed the six Dan furnaces, but there was no effect.

The demon king squirrel and the little bear were conscientious and found a lot of supreme yang things for Zhao, but they saw Zhao Xun's suicidal alchemy process, and their expressions were also very nervous, just like watching Zhao Xun set off firecrackers, and before Zhao Xun carried out the next operation, the two spirit beasts stood together in a shrunken manner, they didn't like the sound of crackling.

What was really distressed was Zhao Xun, who had been flipping through Elder Sun's "Alchemy Experience" all night, inserting one hand into his messy hair, and repeating on his mouth: "What's going on, what's going on......"

Early the next morning, Zhao Xun used the toxin on his body first, and then began to alchemy.

The next day was a little better, and Zhao Xuncai blew up five Dan furnaces, which was one improvement from yesterday.

At night, Zhao Xunshun didn't feel anything, and he didn't have the heart to cultivate, so he went straight to study Elder Sun's "Alchemy Experience", and saw the back in the past.

On the third day, he did not practice the Nirvana Pill first, but refined other pills, because the materials were abundant, Zhao Xun first chose to refine the Ice Run Pill, which was the pill that neutralized the alchemy process, it took an hour, Zhao Xun refined it, the color was extremely poor, the Ice Run Pill recorded in the book was pure white, but the Ice Run Pill refined by Zhao Xun was directly gray, and there was a serious smell on it.

No matter what, Zhao Xun was still very happy, after all, this Bing Rundan proved that he was not messing around in the past two days, and there was nothing wrong with Elder Sun's book.

In this way, his confidence in refining the Nirvana Pill was even greater.

Of course, the effect on the third day was not good, and Zhao Xun's Dan furnace blew up six more.

On the fourth day, Zhao Xun not only refined the Bingrun Pill, but also refined the Mud Pill Pill and Dinghai Pill, these pills were all used for neutralization, Zhao Xun practiced better and better, but the Nirvana Pill basically had no effect.
