Lin Feng wanted to cultivate the Dan Dao, it was completely to improve his cultivation, and it could be said that in his heart, he actually had no interest in the Dan Dao.

However, at this moment, Lin Feng only glanced at this Dan Dao foundation, and he was attracted to it, making him unable to extricate himself, and completely immersed himself in the ocean of this Dan Dao foundation.

Countless strange pill recipes, countless whimsical alchemy methods, countless strange ideas, and countless unexpected alchemy herbs attracted Lin Feng to it one by one.

Before they read this book, Lin Feng thought that the wild grass on the side of the road was the wild grass, but after reading this book, he found that the wild grass on the side of the road, the wild grass in the mortal world, was also a medicinal herb and could be used for alchemy!

Wild grasses, wild flowers, tree bark, and even stones, everything can be used to refine elixir!

Generally speaking, the essence of this book, the dominant meaning, is that in this world, no matter what it is, everything can be alchemized!

It can even be said that this world, this heaven and earth is a medicinal material, as long as the cultivation is enough and there are enough means, then this heaven and earth can be refined into pills!

Lin Feng was immersed in it, forgetting together, forgetting the time

A year later.

Lin Feng was still studying the foundation of the Dan Dao.

At this time, Su Yunqing and the three of them, they finally returned from their studies, rushed out of the Huangquan Cave, and came here.

At this time, Su Yunqing and the three of them, they all looked extremely embarrassed, but from the momentum emanating from them, it could be seen that the six years of cultivation had made them all make great progress!

As for Li Yan'er, she has been alchemy for the past six years. And the elixir she refined was a pill that increased lifespan, of course, this was all she refined for Lin Feng.

However, how could the life-increasing elixir be so easy to refine? It took her six years. I just refined one!

Pills that increase lifespan, without exception, every pill, no matter what kind of pill, can only be taken once, only the first time will increase the lifespan, if you take it later, it will not increase the lifespan, only slightly increase some vitality.

So. The elixir that Li Yan'er wanted to refine this time was different from the last time, and the difficulty of refining it was much more difficult than the last time.

As for the ten old men who came in with Lin Feng, there were only three left at this time, and as for the seven people, they had run out of life and had already died.

And the remaining three, Lin Tian after Su Yunqing and the others came out. He didn't pay attention to them either, and gave them freedom. Let them go, or stay.

And their choice is to stay here and spend their old age in peace

Outside of the formation of the Two Realms Mountain Range, the mysterious old man had already come here before the Two Realms Mountains were closed.

After he came here. He found that Lin Feng didn't come out, and he, after hesitating for a long time, didn't go in to find Lin Feng, after all. He also knew the legend that there was nowhere to enter the mountains of these two realms, and he would definitely not enter them unless he had to.

As for Lin Feng's safety, he was not worried, he believed that Lin Feng would not die so easily!

Therefore, he decided to wait here, waiting for the next time the Two Realms Mountain opened, he believed that if Lin Feng hadn't died, the next time the Two Realms Mountain opened, Lin Feng would definitely come out.

At the same time, he also had another plan in his heart, that is, what should he do if Lin was sealed.

And this plan is also very simple, that is, after the next time the Two Realms Mountain is opened, if Lin Feng can't come out, then he will go in!

You must know that his vitality is running out, and the reason why he wants to find Lin Feng is also to survive, if Lin Feng dies, he can only enter the two mountains to find a glimmer of life!

Dozens of miles away from this mysterious old man, there is also a group of people here at this time, and this group of people is Zhao Xun and others!

They saw that the Two Realms Mountain was closed, and Lin Feng did not come out, so they returned to the family at this time, and the family's order was to let them wait here for thirty years, and wait until the next time the Two Realms Mountain opened, if Lin Feng came out, then continue to follow Lin Feng, if Lin Feng did not come out, then they could return to the family directly!

And in the past ten years, they have also discovered the existence of the mysterious old man.

However, they didn't know this mysterious old man, and they didn't associate it with Lin Feng's body, they only thought that this old man, like those old men, was a person who wanted to go to the mountains of these two realms to win a glimmer of life, and they didn't pay attention to it.

"Brother Xun, you said that the family is true, the people who entered the Two Realms Mountain have not been able to come out alive, why do you say that the family let us wait here?" said one of the disciples with an impatient expression.

Hearing this, Zhao Xun smiled slightly, and said, "Isn't it okay to wait? Now ten years have passed, if we are in the family in the past ten years, I am afraid that we will have to carry out a lot of dangerous tasks, maybe, we have all sacrificed in the mission! And here, although it is boring, at least we are safe!"

Moreover, we are also carrying out the mission of the sect now, and when the mission is over, we will inevitably be rewarded by the family! As for the remaining time, there are still twenty years, and in these twenty years, we can still be at ease for twenty years, and when the time is up, we can leave here. ”

In Zhao Xun's heart, he didn't think that Lin Feng would come out of the Two Realms Mountains alive, after all, the Two Realms Mountains had existed for countless years, but no one had ever come out alive.

The rest of the people, listening to Zhao Xun's words, also reflected it, thought of this, and then showed a smile on their faces

Spring goes to autumn, snow falls and turns into water, and the years are like the silk hair entwined around the fingertips, slipping down, and it is not easy to notice, ten years have passed.

During these ten years, everything in the outside world has been so calm, and nothing has changed.

And in the Two Realms Mountain, Su Yunqing and the others have all taken a step closer in their cultivation in the past ten years.

The remaining three old men, after experiencing these ten years, have all fallen.

As for Lin Feng, it has been ten years, and he is still watching the things on the foundation of this Dan Dao.

Although the foundation of this Dan Dao does not look thick, only a few inches or so, and when you open your eyes and read it, it is not difficult to find that there are only a few or nearly a thousand pages, but if you look at it with your divine sense, it is completely different, and the nearly 1,000 pages have become tens of thousands of pages!

Of course, with Lin Feng's current ability, it wouldn't take him so many years to look at tens of thousands of pages, and the reason why Lin Feng took him so long was because he had read it more than once, he had already read this Dan Dao foundation several times, and every time he read it, Lin Feng would have a new understanding.

This made Lin Feng immersed in it all the time, and he took the trouble to look through it over and over again.

And if this matter is known to the Medicine King, he will definitely be shocked and envious!

When he was watching this Dan Dao foundation at the beginning, he only watched it once, and when Jean watched it a second time, he didn't have any new insights.

Of course, all this is because of this so-called Medicine King, his talent in the Dan Dao is actually not high.

However, this incident also happened to prove the strength of this Dan Dao foundation!

That medicine king's talent in the Dan Dao is not very high, but he can also become the admirable medicine king after reading it once, which is enough to explain everything.

Lin Feng closed the Dan Dao foundation, took a deep breath, and showed a look of enlightenment on his face.

This time I watched it, so he gained a lot of hearts and gained a lot of experience!

Subsequently, Lin Feng calmed down and began to digest the harvest and experience obtained this time.

A day later, Lin Feng opened the foundation of the Dan Dao again and looked at it again.

Not far away, Li Yan'er looked at Lin Feng's actions for more than ten years, even if she was a fool, she also understood that Lin Feng had seen the mystery of this Dan Dao foundation, and was watching this Dan Dao foundation!

However, after Li Yan'er learned about this, she didn't have any envy in her heart, nor did she have any jealousy, she was just happy, happy for Lin Feng.

Su Yunqing didn't know when he appeared next to Li Yan'er, looking at Li Yan'er's appearance, he smiled slightly, and also looked at Lin Feng, and said with a smile: "I know that you also like him, but I won't give him to you, but I know that a person like him will soar into the sky in the future, I can't monopolize him alone, we can be together"

"What?"

When Li Yan'er heard this, her expression was suddenly stunned, and when she reacted, her face suddenly turned red, revealing a shy look, and she said in a low voice: "What are you talking about? How can I like him? He is just my junior brother!"

Su Yunqing smiled and said, "Okay, I've thought too much, since that's the case, then after his retreat is over, I'll tell him that you don't like him!"

"Ah don't" Li Yan'er was shocked in her heart, and said subconsciously, and as soon as the words fell, her face turned even redder, and she lowered her head directly.

Su Yunqing laughed, stopped talking, and walked directly to the side.

Li Yan'er looked at the back of Su Yunqing leaving, sighed, glanced at Lin Feng again, and then turned around and left.

Time flies, and in the blink of an eye, five years have passed again.

Lin Feng put away the Dan Dao foundation in front of him and stood up with a smile on his face.

Sixteen years, a full sixteen years, Lin Feng has been studying this Dan Dao foundation for sixteen years, and at this time, he finally remembered everything in this Dan Dao foundation thoroughly, and at the same time, countless experiences have also accumulated in his heart.

The current Lin Feng, no one knows how high his attainments in the Dan Dao are, but one thing is certain, the current Lin Feng, he decided that he is not an ordinary alchemist can compare!

Of course, I have to say that what Lin Feng has obtained now is all theories, after all, he has never refined a single pill. (To be continued......)
