Mountain Gate

People walk towards the mountains. The mountain gate is the fairy gate. In order to find a crack in the sky that should not exist, a lonely chemist Su Yuanyou turned himself into a heretic in the mortal world. Inheriting the "Tiangong Notes" passed down from our ancestors, we used steam and gears to push history to an unexpected turn. Together with the guards abandoned by the sky, he was involved in a desperate journey to find the "Mountain Gate".
