After staying on the second layer of the blood-red ring for two days, Shen Feng's injuries had already completely recovered.

Before, it had only been long since he had broken through to the sixth layer of the Primordial Xuan Realm, and he planned to stabilize in this layer for a few days, so he didn't absorb the Xuan Stone.

This phantom man is too pitiful, so he will give him a few powerful combat skills!

Shen Feng was going to go to the Library Pavilion of the Cloud Sky Divine Sect first to see if he could find a few combat skills suitable for his current cultivation!

Since a month inside the blood-red ring, only a short day will pass outside.

Therefore, after staying here for two days, when Shen Feng returned to the room, the time in the Heavenly Domain had not long elapsed!

Pushed the door and walked out.

This courtyard is very large, when Xiao Ningyu and the others came here with Shen Feng before, the outer disciples who lived here didn't want to get into trouble, so they hid in their rooms and didn't dare to come out for the first time.

At this moment, Shen Feng suddenly pushed open the door, just in time to see a few disciples walking around in the courtyard.

Seeing Shen Feng coming this way, they left the courtyard in a hurry.

Although Shen Feng was not able to challenge Elder Chang Hongyue, Shen Feng's combat power was obvious to all, and they would not be his opponents at all.

When Shen Feng saw these outer disciples, it was as if he had seen a ghost, and there was a burst of helplessness on his face.

Seeing that another outer disciple came out of the room, he should not have known that Shen Feng was outside, so he didn't wait for him to walk back and close the door.

Shen Feng pointed his finger at this guy and said, "Come here!"

Directly pointed at by Shen Feng, the outer disciple couldn't dodge it, and his face was like a dead father's expression, and he reluctantly walked in front of Shen Feng.

"Senior Brother Shen!" the outer disciple shouted with a sad face.

Although he started earlier than Shen Feng, who made Shen Feng's combat power demonic!

After a brief understanding, Shen Feng knew that this guy's name was He Lei, and he was cultivated to the sixth layer of the Chu Xuan Realm, and he was also well-known in the outer gate, but he didn't dare to be presumptuous in front of a cow like Shen Feng.

After Shen Feng asked the location of the Yunxiao Divine Sect Library, he originally wanted to leave the courtyard directly, but He Lei couldn't help but ask, "Senior Brother Shen, why did your injuries recover so quickly?"

After a short period of contact, He Lei judged that Shen Feng was not an unapproachable person, and besides, just talking to Shen Feng for a few words, he should not be retaliated against by Chang Hongyue.

Hearing this, Shen Feng just wanted to know about the Restoration Bone Fluid and the Recovery Fluid, so he told him about the two spiritual liquids that Xiao Ningyu and Mu Qingxue gave him.

He Lei's face was full of envy, and he said: "Senior Brother Shen, Senior Sister Mu and Senior Sister Xiao really have nothing to say to you, these two kinds of spiritual liquid are expensive, at least they should be regarded as second-grade spiritual liquid, which is not something that ordinary people can obtain." ”

Shen Feng sat down on the stone chair in the courtyard and said, "You also sit down and tell me in detail about the origin of these spiritual liquids." ”

He Lei knew that Shen Feng was from the Immortal Realm, so he naturally wouldn't feel strange about this question, he hesitated, but still sat down opposite Shen Feng and said, "Senior Brother Shen, I once dealt with a person from the Immortal Realm, and I heard that there are alchemists in your Immortal Realm, and there are heart refiners in our Heavenly Realm, which is similar to your Immortal Realm alchemists. ”

"However, the heart refiner is far superior to the alchemist, and it can even be said that it is not comparable to the alchemist at all. ”

Perhaps because he felt that his words were a little inappropriate, he cautiously glanced at Shen Feng, and saw that the other party did not have any change in expression, so he slowly breathed a sigh of relief in his heart.

Shen Feng said casually: "You don't have to be so restrained, tell me about the heart refiner in detail." ”

After hearing this, He Lei relaxed a little more and said what he knew.

The so-called heart refiner pays attention to the word "heart refining".

In the immortal realm, you need to awaken the Origin Fire before you can embark on the path of true alchemy.

And in the Heavenly Domain, if you want to embark on the path of refining your heart, you need to awaken the Heavenly Fire in your body, which is a flame that far surpasses the Origin Fire.

After awakening the Heavenly Fire, you need to temper your heart and carve out a space in your heart, just like a small storage ring.

After successfully opening up space in the heart, it is necessary to let the Heavenly Fire enter the space of the heart, and condense a Heavenly Fire Powder Ding in it.

The heart refiner can absorb the energy in various heavenly materials and earth treasures, gather it into the heavenly fire medicine tripod in the heart for refining, and finally form various spiritual fluids and divine medicines.

Due to the strength of the Heavenly Domain's Heavenly Treasures, the Origin Fire of the Immortal Realm could not work at all.

Although the Heavenly Fire can also be released, the spiritual liquid that is refined outside the body by using the Heavenly Fire and finally refined will only be defective products that do not enter the stream.

Only by refining it in the heart can we refine the true spiritual fluid and magic medicine, and so on.

This heart refiner is divided into one to nine grades.

And those who awakened the heavenly fire and did not open up the heart space are called heart refining apprentices, and they can only refine defective products.

When the heart refiner is refining various spiritual liquids and divine medicines, it is also a kind of cultivation of the heart.

It can be said that the most powerful part of the heart refiner's body is the heart, and even some truly powerful heart refiners can have a heart that can be strong for eternity.

He Lei doesn't know much about heart refiners, but he only knows some fur.

After Shen Feng listened, he fell into a few seconds of contemplation and said, "Do you know how to awaken the Heavenly Fire?"

He is very interested in the heart refiner, and if he wants to grow up in the future, he will definitely need a lot of spiritual fluid and magic medicine, and he must embark on the path of heart refining by himself.

He Lei was shocked and said, "Senior Brother Shen, don't you want to embark on the journey of heart refining?"

"In today's Heavy Heaven, the highest level is only a fourth-grade heart refiner, and opening up space in the heart is tantamount to a matter of nine deaths and a lifetime. ”

"It's not easy enough to awaken the Heavenly Fire, but only one of the thousand people who awaken the Heavenly Fire can successfully open up the space in the heart, and finally embark on the path of refining the heart. ”

"And the other nine hundred and ninety-nine people, most of them will have their hearts burst and die, and the few who can survive will also be left with serious sequelae and will no longer be able to continue cultivating. ”

Speaking of which.

He Lei seemed to recall the sad past, he frowned and said: "Senior Brother Shen, when I was very young, I witnessed the scene of an elder in the family, when he opened up the heart space, his chest exploded directly, and his heart instantly turned into blood mist. ”

"The Heart Refiner is like the Inscription Master, and he has a very high status in the Heavenly Domain, but there are too many risks and tortures to bear behind this. ”

Shen Feng would not give up because of these words, as the phantom man in the ring said, he was the one who was going to break the heavens, so he knew that he had to shoulder more pressure, no matter how many obstacles there were ahead, he had to grit his teeth and move forward, even if he would be bruised all over his body, even if he would be crushed to pieces, for the sake of his loved ones, he would have to finish this journey.

Without asking any other questions, Shen Feng prepared to go to the Library Pavilion after thanking him.
