Immortality? I Will Live on Till the End of Time

At the beginning of the Hongmeng, there are constant killings in the world, and the road to immortality is a mountain of corpses and a sea of ​​blood. Jiang Chen came through time travel with mediocre qualifications, but he awakened to the mysterious ancient book. While others competed for supremacy, he farmed, while others seized treasures, he refined elixirs, and hid in the mountain gate and grew up in a miserable way. Until one hundred thousand years later, the war between immortals and demons swept across the heavens, causing the heavens and the earth to collapse. A supreme immortal emperor came to the mountain gate, smiled evilly and slapped down with his palm—— After the smoke cleared, Jiang Chen slowly crawled out of the kilometer-deep pit with a confused look on his face: "Who hit me just now?" The Immortal Emperor's pupils were shaking: "Impossible! With this palm of my hand, all the heavens will collapse!" Jiang Chen suddenly understood and smiled shyly: "I'm sorry, I seem to have... Accidentally become a saint."
