A Little Energy and Blood into Gaowu? I Create Eternal Disasters

[Not brainless] [No system] [Plot flow] [Invincible] [Behind the scenes] [Natural disaster] Thousands of years of catastrophe, invasion of all races. Barrier cities became humanity's last source of fire. Gu Wuyan came through time travel and had only a little energy and blood for more than ten years. Everyone knew that the orphan named Gu Wuyan in No. 2 Middle School was a loser. He has 1 point of qi and blood, and works part-time as a bone picker in a processing plant. He is usually so docile that he has no sense of existence. Until the unexpected awakening of the only hidden extraordinary sequence - [Natural Disaster]! [Shadow Abyss·Immortality]: As long as there are shadows in the world, the host's physical body will be indelible! Every time you kill a strange beast and absorb the power of death, your energy and blood can be superimposed without limit! No skills required! No pills needed! As long as you kill, you can explode unlimited troops! When hundreds of millions of shadow troops crawled out of the night, the entire Gaowu world trembled! Gu Wuyan sat in the Shadow Throne high in the sky, overlooking all living beings. "I am the shadow of all things, and all things should surrender." "Again, I'm really just an ordinary high school student."
