In the spacious cave, the aura is rich, and there are crystal clear luminous stones inlaid everywhere, which illuminates the entire cave house transparently, like day, and a faint mist rises, giving the cave a hint of hazy feeling.

Lin Feng sat in the groove of the cave, and his lower body was soaked in stone liquid, which was a naturally generated treasure liquid in the cave, which was very versatile and could also be used to heal wounds.

The injuries in the flesh have generally recovered, but the bones are not so easy to recover, but Lin Feng's cultivation has the Heavenly Fall Curse, and this injury is not a big problem for him.

It had been more than twenty days since he had entered the middle stage of the psychic realm, and it was only at this time that he had a good understanding of the changes that had occurred in himself after the realm was raised.

When I was in the forest, I was trapped at the bottom of the river for a long time, but I was in a state of tension at that time, and I couldn't calm down and carefully observe the changes in my body.

In the middle stage of the psychic realm, in general, there is not much change from the early stage, it is nothing more than that the physical body and spiritual power have been strengthened to a certain extent, however, Lin Feng did not break through the realm with ordinary cultivation methods, but directly broke through when absorbing dragon qi.

Dragon Qi is extremely precious to any monk, even if the cultivation has nothing to do with Dragon Qi, his improvement in other aspects of the monk is also huge.

Lin Feng didn't care about the dragon qi before, because there was a drop of dragon emperor essence blood in his dantian, so he naturally didn't look down on that wisp of unformed dragon qi. However, although the essence blood was in his body, it never moved, and it did not give him any benefit.

But the dragon qi is different, since it entered Lin Feng's body, it has gathered in the dantian, compatible with his aura, and then it has been refined and fused into his limbs and hundreds of remains.

It can be said that as long as Lin Feng is willing, he can now directly start to impact the late stage of the Psychic Realm, because there is a dragon qi to make up for it, there is no situation where the foundation is unstable and the spiritual energy is insufficient.

But Lin Feng obviously wouldn't do this, he had just entered the middle stage of the Psychic Realm, and in this realm, there were still too many things to excavate. Monk cultivation is actually to use the creation of heaven and earth to release the potential of the human body in order to obtain greater strength.

"Danfang ......" In the stone liquid, Lin Feng whispered to himself.

He had already learned the Heavenly Cold Transformation Secret Technique, but in just three days, it was impossible for him to completely master this Heavenly Cold Sect's secret method that had dominated hundreds of millions of miles of rivers and mountains for thousands of years.

After the water balloon appeared on the surface of his body for the first time, there was also an extra pill in his mind, although it was a pill, but there were no medicinal materials required for alchemy, only the steps of refining.

"Take the mountains and rivers and the earth as the furnace, draw the sun, moon and stars as the fire, borrow the power of heaven and earth, use your own aura as medicine, and refine an immortal pill that protects your body......" Lin Feng silently recited in his heart, the words recorded on the Dan Fang.

Zhang Hao and the others also had this pill formula, but after reading it, everyone didn't understand how to refine this so-called immortal pill.

Song Hang was born in a family of alchemy, although he gave up Dandao, but after all, he has been in contact since he was a child, and he also has some opinions on alchemy. However, he had never heard of such an alchemy method, and there was no record of it in their family.

From a literal point of view, this pill recipe is to refine itself as a pill, or in other words, to use itself as a guide to refine the water balls of the Heavenly Cold Transformation Divine Recipe into an Immortal Treasure Pill.

But all they can know is that, how to use the mountains and rivers as furnaces, and the sun, moon and stars as fire, this is the problem.

"Senior sister, do you know?" Encountering this kind of lack of knowledge, Lin Feng had no choice but to ask Yu Xuan, and other than that, he had no one to ask.

"I've heard of this alchemy method, but if you want me to explain it to you, I can't help it. Yu Xuan said a little helplessly.

"Why?" Lin Feng was puzzled, knowing why he couldn't explain.

"This is a very special alchemy method, to be precise, this is no longer alchemy, this is refining people. The so-called furnace is not a real furnace, and the so-called fire is not a real fire.

This is a very ethereal method, you need to rely on yourself to understand, if you can't realize it, let alone whether you can refine it successfully, you can't even open the furnace. Yu Xuan explained as much as she could, this ethereal alchemy method is really difficult to explain.

Lin Feng frowned, relying on enlightenment? Isn't this the same as learning exercises or secret techniques? However, there is at least a cultivation method for the secret art of the exercises, and this Danfang has nothing, so he said a few words that are not boundary, how to understand?

"It's a real problem. Lin Feng's face was helpless, the secret method had been initially introduced, and there was a way to continue cultivating, but he didn't know where to start, and he had a feeling that he didn't know where to start.

Yu Xuan is also thinking, she is not omniscient, there are some questions, even her master does not know the answer, no one can truly understand everything in the world.

However, Yu Xuan is well-informed after all, although this matter involves his knowledge blind spots, she also has a way to solve it.

After a while, she suggested, "If you really want to know how to refine this pill, why don't you try the alchemy yourself, and maybe, when you have an insight into the Dan Dao, you will know the answer." ”

"Learning alchemy?" Lin Feng looked startled, and his face was a little surprised.

It wasn't that he hadn't thought about alchemy, but he didn't have the talent for it, and Yu Rou had told him a long time ago that instead of wasting time in this area, it was better to concentrate on cultivating martial arts.

The path of cultivation is the same as that of different paths, and any road, when it reaches the top, is no worse than other roads, and the most important thing is to choose the path that suits you.

Seeing Lin Feng's expression, Yu Xuan guessed what he was thinking, so he continued: "Yu Rou's previous words are not wrong, people who are not suitable for alchemy, forcibly wasting time on it, will only outweigh the gains in the end.

For you, cultivating martial arts is indeed the most correct path, but just because this time and that time was not suitable for alchemy, it doesn't mean that it is not suitable now. ”

When Lin Feng heard this, his expression was even more surprised, and he asked puzzledly: "How can you say that it takes time to learn alchemy?"

"Of course you have to divide it. Yu Xuan nodded and continued: "It's not just alchemy, any path of cultivation must pay attention to timing when stepping in. I didn't allow you to learn secret techniques until you reached the Psychic Realm, but now I'm still stopping you?"

Lin Feng nodded, in terms of secret methods and secret techniques, Yu Xuan really didn't stop him anymore, and also taught him the divine method "Star Introduction", as well as the powerful sword technique. Although the sword technique does not have a name, it seems to be just an ordinary move, but it actually belongs to the category of secret arts.

"Before I arrived at the Psychic Realm, I was because the spiritual energy in my body was still unstable and sufficient, and my divine sense was too weak, and I might not gain more than I gained by contacting the secret art too early, so why was I able to learn the method of alchemy now? Lin Feng asked puzzled.

"Didn't you say it yourself, you used to be too weak, but now it's different. Alchemy requires your understanding of the medicinal properties of the elixir, the control of the heat, and the attention to many details, which is extremely demanding for the divine sense. ”

Yu Xuan's figure floated out of the Holy Emperor Ring, suspended in the cave, and her palm like mutton fat jade stretched out, and a flame appeared in the palm of her hand. The flames were like spirits, beating freely in her hands, sometimes large and sometimes small, hot and cold.

"This is the control of the fire, once you had a weak sense of consciousness, and when you practiced swordsmanship, the control of strength was very rough. It's not as fine now, but it's a lot better than before. ”

The flames disappeared, Yu Xuan waved her arm, and it was clear that there was no sword in her hand, but a sword qi appeared out of thin air. This was a slender sword qi, which looked relatively small and did not have a majestic momentum, but Lin Feng could feel a terrifying energy from it.

This is the essence of the real condensation, the huge sword qi is condensed into such a thread, and the power is gathered in one point, once it is hit by the sword qi, its power can be imagined.

Even if Lin Feng had practiced swordsmanship for so long, it was still difficult for him to control the aura and strength so finely.

After a brief demonstration for Lin Feng, Yu Xuan continued: "After the divine sense is strong, it is much easier to control the strength, and when refining the pill, the control of the Danhuo is the same. Of course, in addition to a strong divine sense, you also need to practice constantly. ”
