Fantasy: the Engagement Was Canceled at the Beginning

After waking up, I found that I had traveled to a fantasy world, and was still the useless young master of a small family. In a few days, the inner disciple of Xuanwu Holy Land, my ex-fiancée, would come to break off the engagement... Fortunately, there is a sign-in system. A big gift package for newbies at the beginning: the innate Taoist body, which can be promoted to a greater realm. Every time you sign in at a place, you will get rewards. The rewards are random... Wouldn't it be invincible if you have this golden finger? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
