Which World Did You Go to to Help Again Today?

There is no pursuit of life and death, no bitterness and hatred. The protagonist travels through some secondary planes that "need a little help", using modern life wisdom, a little super power or pure warm-heartedness to solve the local people's minor troubles and gain sincere gratitude and interesting souvenirs. Young Lin Wan received a "mutual aid platform from all walks of life" and began his warm daily life. He went to the world of martial arts to help heroes cure hair loss, went to the world of immortals to guide alchemists in optimizing the assembly line, and went to the apocalypse to teach survivors how to grow mushrooms... He was kind and principled, and helped in a measured way. While curing others, he also found the most comfortable life for himself.
