Sickly but a Sword Immortal

Everyone says Yun Wangchuan has two things: an inexplicable illness, and unmatched beauty.

That is, until the battle between immortals and demons. Yun Wangchuan covers his mouth with a handkerchief and coughs up blood, then draws his sword the next moment. His sword energy is like frost, cutting through autumn grass, and everything in its path falls.

That day, the setting sun was as red as blood, staining the sky and earth. The survivors watched Yun Wangchuan calmly sheathe his sword, slowly take out a handkerchief, and continue coughing blood. They fell silent.

Later, everyone called Yun Wangchuan the Sword Immortal in the Clouds.
