Longevity: Time Is Like a Knife, Cutting Off All the Old Guests in the World

[Eternal Life + Slow Management + Decisive Killing + Historical Deduction] After traveling through time and becoming a jailer in the Tianlao of the Great Wei Dynasty, Li Qing discovered that as long as he ate and slept, his lifespan would increase indefinitely. In this era when human life is worth less than grass, Li Qing just wants to stay quietly in the prison and master the "Turtle Breathing Kung Fu" that no one has practiced to the full level. He once gave a decapitated meal to the destitute prince, obtained the "Qi Nourishing Technique", and opened the door to immortality; he once collected the body of the peerless empress, obtained royal secrets, and watched the changes; he once guided a little beggar, and sixty years later, the little beggar became a powerful general who controlled the country. The grievances in the world, the dynasty's struggle for hegemony, the immortal sect's battle... These are just passing clouds in Li Qing's eyes. "You fight for your world, and I will cultivate my immortality." Until that day, the gates of heaven opened wide, and the immortals appeared and wanted to slaughter the world. At this moment when everyone was kneeling down in despair, the old jailer who had been guarding the gate of the sky prison for three thousand years slowly pulled out the rusty iron sword in his hand... "It disturbed me to sleep, get out."
