Capítulo 305: A Demon?

"Ha… Ha… It's finally done." Nathan panted heavily.

His body was drenched in sweat as he looked extremely tired.

Vivian stood up while saying, "Yeah. It's done. You have swallowed 26 mature class cores. This should bring your Ena to above 10,000. It's going to be hard to calculate that Ena at this point, so I have been working on a machine that can measure your Ena.

"It's going to be completed soon. At that point, we can even count Ena up to ten million Ena pretty easily.

"I have never thought you would think of a concept of measuring crystal, Nathan." Vivian smirked.

"Ahahaha." Nathan let out a hollow laugh, thinking, 'I only told you about the cultivation world's measuring crystal. How many cultivation stories do you think I have read?'
