“Do you teach anything I want to learn?”

“Crap, otherwise why would I come to teach you as a home tutor.”

“I want to learn how to kiss.”

“……”

I originally thought that when I was going to tutor i was going to meet a little puppy, I didn’t expect it to be a little wolf dog.

Later, Yu Wan looked at Han Ye seriously: “Sorry, I have never considered finding a boyfriend younger than me.”

In the Canglan Continent, there existed a rule: only those who managed to awaken a Martial Spirit were able to pursue the path of cultivation, and a Martial Spirit’s rank was determined when it was awakened. Born in Linshui City, Qin Nan was a peerless genius who possessed great talents and was highly anticipated to become a great cultivator in the future. However, things changed when he ended up awakening the lowest-grade Martial Spirit, resulting in him being considered trash.

In a time when the Divine Prefectures of the East Sea were in great disarray, Emperor Ye Qing and Donghuang the Great appeared to save the day. Under their rule, the prefectures united and all nations as well as their kings have been controlled. However, the legend of these two great heroes becomes altered when Emperor Ye Qing’s name is wiped from the history books after his sudden death. All statues and images of him were destroyed and his name a taboo. Only the legend of Donghuang the Great shall live on.

Fifteen years later, a young man by the name of Ye Futian begins his journey in search for his true identity. The legend of Futian was going to be one for the history books.
