Dou Po: Sign in to Be Invincible, I Am the Second Brother Xiao Yan

Traveling across Dou Qi Continent, I became Xiao Yan's second brother - Xiao Yan. Traveling through the Xiao family coincided with Xiao Yan hitting rock bottom and being ridiculed by his tribe. The Xiao family has three losers, the eldest brother is mediocre, the second brother is useless, and the third brother is in ruins, but they don't know that I, Xiao Yan, have a plug-in to awaken the invincible sign-in system. All I have to do is walk on the mainland and sign in, and the rewards will be unlimited. (Reward for signing in at the Xiao Family Martial Arts Arena: Supreme Body of Ten Thousand Fires, invulnerable to all fires, able to refine strange fires at will) (Reward for signing in at the place where Xiao Yan becomes a disciple in the back mountain: full level Burning Jue) (Reward for signing in at Tagore Desert: Origin of Qinglian Earth Core Fire) (Signing in at Jianan Academy will reward you with Fallen Heart Flame) A three-year agreement? Xiao Yan doesn't need to endure and practice hard, I can overthrow the Yunlan Sect by myself. While Xiao Yan was still struggling to survive, I was already racing all the way.
