Someone once became the last one to wield a knife that could decapitate huge dragons and bathed in dragons’ blood. Someone once loved treating others to chicken soup, so he kept nine phoenixes in his backyard.

Someone once sat lazily on the top of mountains as his words flooded river banks, and his qi could hold a million soldiers back. Someone once moved mountains and shifted hills with just one brush, his paintings so captivating it could enchant immortals and deities.
