I'm in High School and the System Says I'm in a Different World?

Li Miao was accidentally bound to the "Adventurer System" and received a mission at the beginning - to close the gate of hell. However, apart from the open door of the host's house, where is the door to hell? Is this system serious? For the reward of 3,000 yuan, he still kicked the front door of the residence with a gorgeous flying kick. "You red egg (bastard), what on earth have you done!" Ai Qingpu, who was wearing bear pajamas and sniffling from the cold, was furious on the spot. Not only did he not praise his flying kicking posture, but he also said something with a funny accent. Before I could explain, the system popped up again. [Dear Lord Brave, you are so lucky to have met an adventurer who has just successfully hunted! Looking at the slightly wary adventurer in front of you, you know that if you want to survive in this world, you must have a partner! The person in front of me has good fighting prowess and is very suitable as a companion. [Task: Establish contact with the adventurer in front of you. [Reward: Improved physical fitness. No, is this right? With this little gadget in front of me, the system says she has good combat capabilities?
