After Saving for Eighteen Years, I Exchanged It for Canglong Dao Body!

Lin Yan, an urban boy who was born in a time travel, had a mysterious panel in his womb that only had a sign-in function. After sixteen years of silently signing in and accumulating source points, once unlocked they were exchanged for the Heaven-defying Canglong Dao Body. He originally wanted to develop in a low-key manner, but due to his display of strength, he was targeted by martial arts families, supernatural organizations and official special departments at the same time. He was forced to use sign-in rewards to stir up the storm in the urban undercurrent.
