Chapter 4240 (1/2)

It's just that it's so painful that even Chen Yu can't hold on to it.

What's more, the higher the level of tempering, the greater the pain. When it comes to the level of little holy land, Chen Yu almost goes crazy and wants to faint.

However, no matter how painful it is, it is absolutely impossible to faint. No matter how painful it is, you can clearly feel the pain.

This is the unbearable place of the hammer bone soul refining formula. This pain can not be shielded or transferred.

Because of this, countless strong people will give up practicing this pithy formula, even if they know that they will get great benefits after practicing it. At the same time, once you can't bear the pain and decide to stop practicing, then not only will each realm not reach the level of perfection, but it will also damage the foundation, reduce the talent, and fall from the level of genius to the mortal.

This kind of consequence, is all talented strong person can't bear, therefore, almost no one practices this hammer bone to refine soul formula.

However, knowing that there would be such consequences, Chen leiming still chose to practice, mainly because of his strong heart and confidence in his own will.

However, under this extreme pain, Chen Yu feels that he is a little overconfident. The extreme pain that makes him feel worse than death, and almost gives birth to his own end, is really a thorough blow to Chen Yu.

This kind of pain makes Chen Yu almost go crazy. He rolls around in the secret room, smashing all the furnishings in the room into pieces.

Several times, Chen Lei couldn't hold on and wanted to give up.

However, whenever Chen Yu wants to give up, he only needs to think about his parents, wife, sister, etc. in the Middle Kingdom, and then adds a little bit of courage and perseverance.

In the end, Chen Yu grits his teeth and sticks to it.

However, this kind of courage and perseverance will eventually be exhausted, and the soul refining formula of hammering bones that he has cultivated is still one level short of perfection.

At this time, Chen Lei is really at the end of his tether. Even when he thinks of his parents, his wife and his younger sister, he does not have the slightest courage to practice the last layer of the pithy formula.

The pain of the last layer of the hammer bone soul refining formula is several times greater than that of the previous layers. As long as he thinks of it, Chen Yu is shocked and starts to think of his own end.

”Hum!” In the end, Chen Yu no longer hesitates and begins to practice the last layer of the hammer bone soul refining formula, because he does not have much hesitation time. If the time is too long, the practice will be regarded as a failure. At that time, Chen Yu's talent will fall to the earth and become a waste man. Chen Yu can't accept the result.

As soon as Chen Leigang practises, he is drowned in endless pain. This kind of pain almost makes Chen Lei want to explode his spirit.

Chen Yu is inundated by endless pain, but he still insists on the trace of reason and does not let himself collapse.

And endless pain, just like the tide, wave after wave of slapping over, endless.

Chen Yu's sense is just like a levee. It is crumbling and may collapse at any time.

Chen Lei really doesn't know when he can stick to it. In this endless pain, there are some deficiencies in Chen Yu's previous cultivation. However, Chen Yu's body is more powerful. His whole body is crystal clear and shining. On his bones, there are mysterious pictures of
