I Thought I Was a Farmer, but My Pets Keep Breaking Reality (Volume 5) by ZenithNovels

Li Fan was content living a simple, pastoral life—raising chickens in the yard and breeding ornamental carps in his pond. But his peaceful existence shatters when he discovers a shocking truth: his supposedly ordinary "Earth Chickens" are actually pure-blooded Phoenixes, and those lazy carps he's been feeding are genuine True Dragons. As celestial beings and ancient powers come knocking at his door, Li Fan remains blissfully in denial. After all, how could a humble farmer like him possibly be a Peerless Supreme Expert? A hilarious, action-packed cultivation fantasy about the most powerful immortal who absolutely refuses to admit it.
