The Replacement Enhancement and The Mental Test.

Before he could log in to the UVR and use his wings without breaking stuff, Felix had to check on his first two passives!

In the past two days before he started his integration, he already requested from Asna to help him etch his void immunity within his 1% human bloodline.

After all, he couldn't replace his void bloodline with 15% essence without losing his void immunity and interdimensional senses.

The only reason everyone preferred etching abilities after the replacement process was due to the mutations.
