Doomsday Positive Energy System

In the last three years since the end of the world, I have been keeping my little brother alive by telling cold jokes. "Brother, today's alien beasts are so funny!" Ten-year-old Lin Xiaopi held up Skittles, followed by a group of laughing beasts rolling on the floor. Lin Mo covered his face: "Ancestor, that's a B-level beast, not a crosstalk audience!" [Ding! The positive energy system was successfully bound! [Detected the cute attack of the host brother, positive energy +100][Unlocked skill: Cold joke critical hit (causing mental damage to the alien beast)] While others awakened the power to destroy the world, Lin Mo could only rely on telling jokes to collect positive energy - "Why don't the zombie programmers work overtime? Because they are not offline!" The alien beast laughed until it twitched and exploded with an A-grade crystal core. "Why can't Liu San catch up with us? Because he failed math!" The pursuer was so embarrassed that he blew himself up, releasing supplies all over the place. It wasn't until that day when he awakened the humanity of the B-class alien beasts with the sentence "The nurse sister's smile was stitched up" that he realized that something was wrong with this doomsday - are the alien beasts the emotional harvesters of high-dimensional civilization? Can my brother's Beast King language communicate with interstellar beasts? And his system was actually the ultimate weapon for ancient humans to fight against the gods! "Brother, they said your jokes can save the world!" Lin Mo looked at the prompt on the panel [Positive energy: 1,000,000+] and silently took out the "Crosstalk Encyclopedia": "No, it's to save my instant noodles inventory." [System prompt: Detected the host's desire to survive, unlocking the ultimate mission - to rule the universe with cold jokes! Etc! This script is wrong!
