I recommend the "Plane Mission Reward System". The protagonist of this urban supernatural novel has obtained a plane system. He can travel through various planes to complete missions and obtain skills and items from the mission world. However, if he fails to complete the mission, he will not be punished. The quest included taming a Type 9 Colossal Dragon, pumping the stomach of the Heaven Devouring Beast, collecting 6 different types of zombie viruses, etc. The rewards included skills and items. Although the quest was a little strange, it was foreseeable that the protagonist would have a lot of adventures and challenges. I hope you like this fairy's recommendation. Muah ~π
