All the Holy and Dark Methods Are Not as Good as My Original Intention

The venomous God of War Zhang Lintian and the "unintentional" genius girl Li Yuanxi accidentally entered the Holy Underworld. The fantasy cultivation middle school, the Wanle Valley, the largest freak show producing place in the Holy Underworld, Fenglang Town, the residence of the mixed-blood demon clan, and the Black Blood Banquet cleverly set up by the Black Feather Clan... Will all be places that the two of them must pass through to practice in this strange world. One is an arrogant young man who wants to speak harshly, and the other is a geeky girl who wants to speak harshly but doesn't mean it. The two walk side by side in another world, and they will overcome difficulties together in an extraordinary way to get the answer to their "original heart".
