Biography of Li Tang

No time travel, no system, no plug-ins. I'm just Li Tang, who started from a humble background, sold himself into slavery, and went from being a dog to being a human being, to escaping from death and wanting to be a god, and starting his own legendary life. With his clever mind and a chance of God's care, he has gone through life and death, been protected by his masters, supported by his teachers and friends, been tempered by his opponents, and achieved mutual success with his enemies. After thousands of years, he has finally reached perfection, stood at the top of the world, and had a glimpse of the great road.
