Mana Link

While Theodore and Lara's private conversation was ongoing, Xu Feng himself had established the mana link with the Mini Earthrender.

Once the mana link was constructed, there was now an intangible sense of aura that was only special between them. 

"It seems like you have grown stronger from the mana link." Xu Feng mused, noticing its sudden surge of aura. 

The reason why he even bothered to establish the mana link with the Registration Link item in the first place was because of this benefit.

Currently, Xu Feng was stronger than the Mini Earthrender, so part of his mana and attributes were shared with it. 

Of course, the sharing does not actually affect his actual mana and attributes. 

It remained the same, but the Mini Earthrender would be similar to borrowing his attributes and mana without actually taking it from him.
