Success or failure depended on this!

If it was feasible, it would be an additional method to increase Zhang Xuan's battle power.

Zhang Xuan naturally wouldn't refuse such a good thing.

"It has to succeed!"

"It has to succeed!"

Looking at the enhancement of the undead, Zhang Xuan clenched his fists!

He was hoping that the strengthening increase would succeed. This way, his battle power would greatly increase!

[Strengthening enhancement completed!]

As the notification popped up, Zhang Xuan became even more nervous. He didn't even dare to look at the results!

After forcefully stabilizing his mentality, Zhang Xuan looked up and saw consecutive notifications on the page.
