Xiao Tian was currently trying to master the fifth stage.
Even though he could feel his blood in his body, he always failed to merge his blood with his energy.
Of course, he did not give up and kept trying to merge them because he wanted to look young forever.
However, no matter how many times he tried to merge them, the result was the same.
He failed!
He could not merge them!
He even could not feel his blood for a moment, as if his blood refused to merge with his energy.
This was the reason why he stopped trying to merge them.
'Elder Shun is right. Mastering the fifth stage is much harder than mastering the previous stages.'
He slowly opened his eyes.
Wan Shun, who saw Xiao Tian opening his eyes, asked curiously, "How is it?"
"I could feel my blood in my body, but I always failed to merge it with my energy." Xiao Tian gave an honest answer.
