My Wife's 90Th Birthday

On the day of his wife's 90th birthday, Cao Yingjun and his wife died unexpectedly! After being reincarnated into the world of fairies and demons, he always felt that a certain alluring woman seemed familiar to him. At the same time, he also had a unique ability. Whenever he laughed and felt happy, the "dopamine" secreted in his brain would not only transmit a pulse, but also split and fuse this pulse to generate huge energy. Therefore, when encountering an enemy whose strength is far superior to his own, he always asks the opponent expectantly: "Can you tell me a joke before the battle?"
