After Turning In My Golden Finger

[This story is entirely fictional. Everyone across the galaxy and the world speaks Chinese. Everything is made up and has no connection to reality.] At some point, Gu Yan began transmigrating every time he opened a door. The time was random, the place was random, and the time and circumstances he transmigrated into were random too. Nothing could be predicted. The only certainty was that a door was the trigger. In his previous life, Gu Yan used this golden finger to make a fortune. Reborn in this life, however, he contacted his biological family at once and handed himself over to the country. From interstellar worlds, he brought back special energy sources, minerals, and advanced technology, making the country's technological development surge forward. From primitive worlds, he brought back herbs that were hundreds or thousands of years old, along with countless enormous fruits, enriching the national treasury. From ancient worlds, he brought back rare treasures, devised ways to reclaim precious artifacts that had been lost overseas, and ensured that all kinds of traditional crafts would not be lost. From apocalyptic worlds, he brought back mysterious crystal cores and developed medicine capable of curing cancer. Watching the Blue Country develop at lightning speed, people across the galaxy went crazy. Other countries: "What on earth is going on with you? Did aliens help you?" The Blue Country's leaders smiled. "No aliens, but we do have one patriotic citizen." Theme: Unity is strength. The country is the best!
