Chapitre 88: Chapter 88 - Absorb technique

Other than that you can also see that he finally learned the cultivation technique or you can say spiritual energy absorption technique. With that, he could finally understand how those other Warriors increase their power using this technique. Well, actually this technique absorbs The Spiritual energy and increases the spiritual energy inside the warrior. 

Using that spiritual energy those Warriors are able to increase their power and are able to break through their limit. Even though he completely did not understand how those people were able to become that much powerful, one thing was for sure, most likely this absorption technique was based on the talent of the warrior. 

Even though he has a rare grade technique, he wasn't able to increase spiritual energy that much. You can say that those people who have average potential, most likely need 2 to 3 days to increase 1% of their spiritual energy.
