After Handing over the Golden Finger

[This article is completely fictitious. Chinese is spoken all over the world in the interstellar world. It is all privately designed and has no connection with reality. I don't know from which day Gu Yan will travel through time as soon as he opens the door. The time is random, the location is random, and the time, space and environment after traveling are also random. Nothing can be determined except that the opportunity is the door. In his previous life, Gu Yan relied on this golden finger to get rich. When he was reborn in this life, he contacted his biological family as soon as possible and handed himself over to the country. …… Bringing back special energy, minerals and high technology from the interstellar world has enabled the current technological development to advance by leaps and bounds. From the primitive world, he brought back thousand-year-old herbs and countless oversized fruits to enrich the national treasury. Bring back rare treasures from the ancient world, design to retrieve lost treasures and cultural relics, and prevent various handicrafts from being lost. In the doomsday world, bring back the mysterious crystal core and develop a drug that can cure cancer. …… Seeing the rapid development of Blue Country, everyone in the galaxy went crazy. Countries: "What's going on with you!? Are you being helped by aliens?" The senior executive of Blue Country smiled: There are no aliens, but there is one patriotic and good citizen. …… Mission: Unity is strength, and the country is the best!
