If I Choose the Ancient Holy Body at the Beginning, I Can Upgrade Infinitely.

The ancient holy body can overwhelm all enemies in the world, and can be jealous of God, who can cast down ten shackles and four curses. No one in the future can master it. Chu Nan did not hesitate to choose because his system can be infinitely upgraded. A stone, upgraded ten thousand times, can kill an immortal. A pill can be upgraded to an elixir. What's even more amazing is that you can upgrade your understanding and deduce everything in the world! The Ancient Holy Body is just the beginning!
