A pretty painful setback

'Since the system has chosen me as a host, I must prove that I am qualified. This is a cultivation technique with no name and no one has dared to give it a name since its inception. Because it is considered a blade technique that can take us to the pinnacle of blades.' Tang Yin replied and walked away from the tree again and looked at it, taking a deep breath, before making a similar move again, which triggered a small explosion, but this time, Tang Yin had missed one of his strikes. 

[Do you have any counter?] the manager asked.

'Of course, the counter is easy, look.' Tang Yin replied as he raised his right arm a little and removed the sleeve of his clothes.

There was a deep open wound there.

This surprised the administrator.

[What the hell is that?] He asked in shock.

Didn't it look like a wound made with a sword recently? Blood was dripping from it, how had he not noticed? thought the administrator.

Tang Yin smiled.
