Art of Rejuvenation.
This was a secret technique used by grade S talent espers to erupt their strength.
Whether it was Li Tiantian or Xiao Die, the reason they worked so hard in the past, it was all for the Art of Rejuvenation. However, out of nine parts, they only managed to obtain three of them before dying to the Tian family. This was why their search for Art of Rejuvenation halted. Even so, that didn't prevent them from understanding the might of Art of Rejuvenation.
One needs to know how powerful it was when Ping Yang only had one in his hand.
Originally, his talent was only equivalent to ordinary grade A talent, but it produced such horrifying effects under the influence of Art of Rejuvenation. Then, when three parts of them were collected, both Li Tiantian and Xiao Die joined forces and actually managed to win a glimmer of hope for Su Hao under Tian Gang's merciless attack!
This is the power of Art of Rejuvenation.
