Resurrection of Spiritual Energy: Defeat the Opponent to Obtain Trophies

I just happened to be in my third year of high school when my spiritual energy revived. I thought I would be the one to win, but I didn't know that I could get trophies by defeating the opponent? "Ding! You defeated the green caterpillar and obtained the opponent's passive skill disguise" "Ding! You defeated classmate A and got a Japanese movie disc hidden by him." "Ding! You defeated the Golden Liger and obtained the extended skill King Kong Grand Hand Seal." "I can understand why you can get the crowbar by defeating the thief, but why can you get its eighth leg by defeating the seven-legged reptile?" This novel and its characters are purely fictitious.
