Ever since Hao Ren started to have frequent contact with the First Born, he knew that he had to increase his resistance to mental attacks because the tentacles had no mercy and that it understood all the weaknesses of all creatures. Strong shields and strong armor might make a man as bulletproof as a superman, but a fragile heart was always the most difficult soft spot to protect. It was a hard thing to get armed, and once it was broken, it would be beyond redemption. Hao Ren had acquired a far more resilient mind after physical intensification and long-term training, but he knew that he still needed some things to keep alive: One's mental strength was a hard indicator, once it was broken, even the most powerful warriors could not save themselves, so he needed some powerful equipment to protect him.
