I'm a Time Traveler, How Could You Trick Me, System?

My name is Wei Yang, a cute little boy from Blue Star. I never expected that today I would travel through time and come to a world full of monsters, monsters, elves and nightmares, and practitioners everywhere. "That's not right! Aren't all time travelers equipped with cheats to make them invincible? Even if it doesn't work, you should be given a world guide or strategy, otherwise how can you play this?" [Boom, the system has heard the traverser's nagging and is officially activated! Wei Yang smiled slightly, "Let me tell you, no time traveler comes empty-handed." [Dear time traveler, in order to prevent you from falling into a box prematurely and making you laugh out loud, the system will provide you with a lottery] [Prize 1: Strength +10, no additional conditions] [Prize 2: Immediately promoted to a yellow-level first-grade magician] [Prize three: a bottle of body quenching fluid] [Prize Four: Reward a Marrow Cleansing Pill] "Can I have them all?" Although Wei Yang doesn't understand the purpose and significance of these things now, it is obviously not wrong to take them all. "No! There are no conditions attached to prize one. Do the others have any?" While he was thinking about it, three meteorites about one meter in size hit the ground around him unexpectedly. The huge collision sound frightened Wei Yang to the point where he sat down on his knees. Looking at the meteorite that was still red and emitting heat waves, he asked, "Are you my system? Why do you feel like you are cheating me!"
