Reciting Huang Ting for Ten Years, Starting with the Immortal Killing Sword

[Travel] + [Revival of spiritual energy] + [System] + [No heroine] + [Decisive killing] + [Semi-invincible] Sun Bodu traveled to an ancient world without gods, demons, ghosts, or extraordinary beings.

I can only live for several decades in a mortal body, but in this ancient world with very underdeveloped productivity... Until ten years later, this world... Its spiritual energy revived! But as familiar names appeared one by one, Tu Xingsun, Huang Tianhua, Lei Zhenzi, Yunxiao... Uncle Sun gradually realized that something was wrong. When that person returned, he would not return the Immortal Killing Sword to him...
