Chapter 4717: Sharpen

The black grinded eyes, like a dark abyss, released a palpitating breath.
At the same time, there are also terrifying heat and fire attribute laws, which are constantly gushing out from the dark and faintly grinded eyes.
Lin Fei found that all the flames that spewed out of that grinded eye were a black flame.
The burning power of this kind of flame is very terrifying, and wherever it passes, it melts time and space into gas.
Therefore, in the surrounding space of the skyfire mill, there is no stable time and space at all.
That piece of time and space has been shaking, like a stream of water.
"Lin Fei, if you want to cultivate your mental energy, you must enter this grind and accept the sharpening of the sky fire."
At this time, the fire source beast ancestor's voice sounded in Lin Fei's sea of ​​consciousness.
"I see, senior."
Lin Fei nodded.
Then, Lin Fei walked towards the piercing position step by step.
As he got closer and closer, Lin Fei realized that there was a mysterious and terrifying energy that began to envelope his body and mind.
Finally, Lin Fei walked to the exit of the sharpened eyes.
Boom...The black flames billowed, spewing more violently, turning into a black sea of ​​flames, continuously flooding towards Lin Fei.
Lin Fei's body was completely surrounded by a black sea of ​​fire.
At the same time, there is a very terrible energy that invades Lin Fei’s body. This terrible energy is like an invisible stone mill, dealing with Lin Fei’s soul, will, thinking, emotions and other conscious things. Sharpen.
"What kind of energy is this? It's so terrible! I'm afraid that those Chaos Gods who are not strong enough will come here, and in an instant, they will be obliterated by this mysterious energy!"
Lin Fei was secretly surprised.
However, Lin Fei knew that the fire source beast ancestor said that the main reason that this skyfire mill can be used to cultivate mental energy is the existence of this mysterious energy.
Because, this mysterious energy, like an invisible stone, can suppress and sharpen the soul, thinking, memory, will, emotion and other conscious things of living beings.
Boom... Inside Lin Fei's body, that mysterious energy was spinning rumblingly.
Ah... Lin Fei couldn't help but let out a scream.
Lin Fei found that his soul body seemed to be placed under a stone grinder, and he was being hardened.
Moreover, this grind is repeated, and the feeling is like that after the soul body is ground, it is reorganized and then ground again.
Every time the soul body is ground, it is very painful.
Moreover, except for the soul body, all conscious activities are being repeatedly ground.
Thinking, memory, will, emotion... etc.! Ah... Lin Fei bit his scalp while screaming, and walked in towards the dark and faintly grinded eyes.
Lin Fei understood that although this kind of grind was painful, if he persisted, it would have tremendous benefits for the improvement of his mental energy.
The Fire Origin Beast ancestor was right, this sky fire mill could be used to cultivate mental energy.
Moreover, the effect is very large and the effect is very obvious.
With the grind time and time again, Lin Fei found that his mental energy began to slowly increase! Originally, at Lin Fei's current level of mental energy, it was not easy to talk about going further.
Under normal circumstances, it is necessary to slowly realize and accumulate for a long time before a breakthrough is possible.
However, now, Lin Fei accepted the tempering of this skyfire grinding, and in a moment, he found that his mental energy was slowly increasing.
Lin Fei also discovered one thing, that is, the more he grinds his eyes into this skyfire mill, the mysterious energy becomes more and more terrifying.
"so horrible!"
Lin Fei couldn't help but smile wryly.
Lin Fei felt that his mind, mind, memory, will, and emotions, and other conscious things, were being ground again and again.
Moreover, the speed and intensity of this grinding becomes faster and stronger! Correspondingly, Lin Fei was suffering more and more! Ahhh... Lin Fei felt a heart-piercing horrible pain! This pain does not come from the body, but from the depths of the soul! On several occasions, when Lin Fei couldn't hold on, he stopped moving forward, no longer grind his eyes deeply, and even stepped back and withdrew step by step.
Until the pain is relieved and you can bear it, then slowly move forward again, grinding your eyes deeply.
Of course, during this process, Lin Fei's screams never stopped.
This kind of pain from the depths of the soul is too terrifying, far more terrifying than the pain of the body being tempered! Even, on a few occasions, Lin Fei was too painful and a little unbearable. His consciousness began to blur and almost fainted.
"hold onto!"
At this time, Lin Fei desperately encouraged herself.
At the same time, it also displays the mental power world, condensing one mental power world after another, and enveloping myself.
Dozens of mental power worlds overlapped Lin Fei.
Lin Fei felt a little better.
However, although this process was hard, Lin Fei found that his mental energy had been steadily increasing.
Time passed slowly.
Lin Fei has been walking toward the depths of the sharpened eyes.
This grind is like a bottomless pit, never going to an end.
Lin Fei was alone, walking slowly and exploring in this way.
"Not bad.
The young man's will is extremely firm.
At the beginning, I was a little worried about whether he could accept the tempering of the sky fire. Now it seems that he is fine and can stick to it.
I don't know, how much improvement will his mental energy be when he comes out of the fire mill? "
The ancestor of the fire source beast looked at Lin Fei, who had been grinding his eyes deep in the sky, and couldn't help but secretly look forward to it.
Ahhhhh... Lin Fei's screams have been echoing inside the sky fire mill, like a wounded, lonely wolf! "Ancestor, Lin Fei is okay."
Lin Fei's screams came from the sky fire mill, awakening the fire source beast who was practising the fire control technique. He opened his eyes, looked at the sky fire mill, and asked worriedly.
He is a family of fire source beasts, and in this forbidden land, he is more and more able to adapt, so he can see the sky fire mill from a long distance.
"Do not worry.
Lin Fei's willpower is stronger than you think.
I believe that he can stick to it. "
The ancestor of the fire source beast smiled.
At this time, the ancestor of the fire source beast was still fighting with the four old posters of the Suiyuelou.
The four old posters of the Years Tower have always wanted to rush to this forbidden area.
However, the fire source beast ancestors have been entangled with them, mobilizing the flame and fire attribute laws in this forbidden land to suppress them.
This makes it difficult for the four old posters to leave this forbidden area for a while.
