One Punch, the Truth

Wu Di is an ordinary person. The only special thing is that when he wakes up every morning, his strength will be doubled from yesterday. At first he didn't care, until one day, an alien fleet invaded the earth, leaving the global military powerless to resist. When all the countries were in despair, Chen Wudi scratched his head and said to the TV camera: "How about you let me try?" He walked out of the atmosphere, stood in front of the alien mothership, stretched out a finger, and gave it a light poke. The entire fleet shattered like a bubble. The alien commander's last communication record is: "There is a 'human being' on Earth, and he is an extraterrestrial being."
