Spiritual Energy Recovery: Two S-Level Guardian Spirit Brothers at the Beginning

After traveling through time and becoming the only son of a terminally ill city lord in the world of Gaowu, Bai Hua was supposed to be the reincarnation winner. Unfortunately, the famous doctor Hua Tuo gave him a countdown to his death: he would not survive until the age of nineteen. In this world where the guardian spirit awakens at the age of eighteen, he drags his sick body onto the awakening stage. His father is the strongest holder of the Bai Qi guardian spirit in the world, and everyone thinks that S-level bloodline is destined to be wasted. When the ceremony started, two golden lights burst into the sky. The legendary brothers of the Tang Dynasty who had disappeared for thousands of years suddenly appeared in the world: "Who else is worthy of inheriting this yin and yang way of living beings?" The world is shocked: Priest assassin? Strange mage? What's even more bizarre is that his two guardian spirits can combine yin and yang to kill enemies across levels!
