I Only Built the Foundation at the Beginning, and I Have Guarded the Human Race for Hundreds of Millions of Years.

[Rise of the human race + hot blood + decisive killing + light system] Lin Han was accidentally transported to the world of immortality by a mysterious bamboo slip. He could have received heaven-defying fortune, but he returned to Blue Star with only a foundation-building pill. That day, a mythical scene suddenly appeared in front of people's eyes. The deep sea hanging upside down in the sky leads directly to the sacred mountain outside the world. A voice sounded from the global broadcasts at the same time: "I would like to inform all citizens of Blue Star that the era of annihilation is over and spiritual energy... Has been revived!" The spirit of the ruins appears in the world, and the human race is in decline. The Chinese Qi Refiners turn the tide and support the building from falling. Lin Han, who was only in the foundation building stage at the beginning, stood on the ruins with his eyes like swords. "I'm going to drive them out without leaving any one behind!" (The system of this book is biased towards the traditional golden finger system. It is not the kind of system where the main character is the main character. There is a male protagonist who is a tool. If you don't like it, please don't criticize me. Thank you^_^)
