Reincarnation Paradise? Don't You Know How to Search, Beat and Withdraw Me?

[Unlimited flow + all worlds + original world + decisive killing + technological enhancement + no female protagonist] How to play Delta? Search for points, fight, and then... Withdraw? I, Lin Feng, the number one rat in the Delta, know this very well. Until the sky is dark and the earth is dark, just for a full-dress evacuation. As a result, as soon as he put on the equipment, he was taken away by the red wolf, and all his life savings were given away. I was so angry that I vomited blood on the spot and my eyesight went black... When I opened my eyes again, I heard a cold whisper in my ears: "Welcome to the paradise of reincarnation." While others struggled to survive in horror movies, I awakened my unique talent - [Harvard Tyrant]! Items brought back to the space can be directly exchanged for exclusive Harvard coins! From now on, firearms with unlimited bullets are just the beginning; powered mechas are daily transportation; while others are still using cold weapons to kill each other, my tank has already entered the enemy's hometown! They say the technology side is waste? I took out Harvick's meteorological weapon with my backhand and used the artificial typhoon to teach him how to behave. Su Xiao cuts the rules with a knife, and I smash them with money! When all the hunters were searching for the source of power, relying on endless Harvard coins, I had become a walking natural disaster. Until I discovered that behind Harvard Coin is a cruel plunder against thousands of worlds... This time, I, the "tyrant", will use my own way to bet on a free future for all struggling creatures!
