I Changed Classes to Become a Celestial Master, and You’re Doing Tai Chi with the Campus Beauty from the Start?

Ye Ran transmigrated into a world where everyone could change professions, becoming the heir of a top-tier wealthy family. His grandfather was a national pillar, and both his parents were S-rank Battle Gods. He had planned to rely on his background and lie flat in peace, but on the day of awakening, he not only awakened the [Celestial Master] profession, he also activated the [Dao Follows Nature: Lie-Flat System]! [Quest: Take a short nap. Reward: Spirit +20] [Quest: Refuse to team up with the campus belle. Reward: Skill [Taiji: Redirecting Force]] Ye Ran was ecstatic. There were actually benefits like this? He was going to lie flat! Thus, while other students risked death countless times in dungeons, Ye Ran was sleeping. While other geniuses sweated like rain in the gravity chamber, Ye Ran was sunbathing with the campus belle, practicing taiji together and enjoying life. Until one day, a boss from a bottomless dungeon descended upon the city. As everyone fell into despair, Ye Ran was forced into action. "Ugh, what a hassle. I'll have to make up for my sleep after this." He casually drew a talisman. The next second, divine thunder descended from the heavens, and the boss was instantly reduced to ash. Everyone: ??? Ye Ran: "I really wasn't trying to show off. The System made me do it."
