My name is Chen Huai’an, and I have cancer. I’m dying. Lately, I’ve become obsessed with a virtual girlfriend game. I top up my account to buy her cultivation techniques and magical artifacts. Even though I’ve emptied my wallet, I laugh like a fool. I always thought it was just a game—until one day, my virtual girlfriend sent me a pill. The next moment, the pill appeared in my hand… Am I… not going to die?!My name is Li Qingran. My cultivation has been crippled, my spiritual roots dug out, and I’ve been expelled from my sect. I cower in a dilapidated hut, waiting to die. I thought my life was over—until I met a mysterious senior who never shows himself. This senior heals my wounds and helps me cultivate. I grow stronger and stronger, eventually becoming the most powerful sword cultivator in the Cangyun Realm. I’ve heard that the spiritual energy in Cangyun is depleting, the Dao is dim, and an immortal from another world plans to merge their soon-to-revive realm with ours. An age of chaos and opportunity is upon us. Even immortals may face death in this struggle. I scour the world for traces of this senior. I want to protect him—and become his Dao companion!!!

He is the ruler of the mercenary realm, an overlord that gives headaches to the leaders of any country! For the sake of his friends, he’s willing to sacrifice himself; for the sake of his family, he does not hesitate to spill blood! He is a dragon, one that soars above even the highest of heavens. He’s a power that advances triumphantly through unstable situations, stirring up both the winds and the waters.
