Fantasy: My Signing in Has Become the Ceiling of Combat Power?

As soon as Li Xiang traveled to the fantasy world, he awakened the most powerful cultivation system. I thought it would unlock the aura of a cool and awesome protagonist. But who knows? The system is cheating. Every day, he is either asked to raise chickens and feed fish, or he is asked to pick tea and plant trees, or he is asked to help the village elders and ladies chop firewood and feed the pigs... —— Until one day, the system told him... What? Is the native chicken I raise a pure-blood phoenix? What? Is the carp I raise a real dragon? Li Xiang expressed a bit confused: No, this is impossible. I eat these things every day. If they were really real dragons and phoenixes, wouldn't I have said ** a long time ago? Just when Li Xiang was still doubting himself... Ding—— System prompt: The host has completed all main missions, and his current cultivation level is automatically raised to the world's combat power ceiling. ... Li Xiang: That's it? I have become the ceiling of world combat power! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
