Chapter 81 entry into the Research Center 1

Room 609.

Su Yu was panting heavily. His body was still a little swollen and painful. Some of the blood on his body had seeped through and covered his clothes.

However, Su Yu could not care less about this. His face was full of joy.

“Iron Wing Bird: Level 2 of ten thousand stones”

“Race skill: Level 2 tearing (blood essence activation) , iron wing strike (blood essence activation)”

[ advanced origin technique: Elemental Essence Stone Volume (Blood Essence Activation)]

The few lines of words made Su Yu extremely happy.

He had really advanced!

Su Yu was not very sure that he could definitely advance. Previously, he had activated the thousand and seven layers. Later on, he had consumed quite a lot of blood essence, and it was likely that he had also consumed the thousand and nine layers. However, he had never advanced.

Now, it seemed that if he wanted to advance, he would have to use a higher layer of blood essence to cover it.
