Prehistoric: Living in Seclusion for Hundreds of Millions of Years, Becoming Invincible Upon Birth

Xiao Chen traveled through the wilderness, awakened the sign-in system, and lived in seclusion on the edge of chaos for hundreds of millions of years. I chop wood, boil water, and drink tea every day, and the sign-in rewards pile up, but I always feel that I am an ordinary person. Until one day, the Jie Cult disciple Jin Ling Sheng Sheng was seriously injured and fled to his island, followed by the murderous Ran Deng Taoist. "Uncle, help!" Xiao Chen looked at the black ax he was chopping wood in his hand and waved it casually—— "Crack!" The acquired treasure, the Heaven-turning Seal, shattered on the spot, and Taoist Ran Deng was wiped out in ashes! Leader Tongtian: "Brother Taoist, do you call this chopping wood?" Taoist Ancestor Hongjun: "Fellow Taoist, what you are cutting is the line of cause and effect of heaven!" Yuanshi Tianzun: "This person's realm is actually higher than that of a saint?!" Xiao Chen looked at the trembling saints and helplessly spread his hands: "I really didn't want to be invincible. I just lived in seclusion for too long, and accidentally... I became too strong." Invincible flow + sign-in + boss behind the scenes + easy crushing + prehistoric godhood
