Take a Brother to 1980

"Hello, I'm here from 2026." "... Where's the letter of introduction?" Lin Yanchen was stuck. He was taken aboard the time ship by Beanbag. Agreed to send him home. I returned home, but I got lost. The time was 1980. Without a letter of introduction or certification, you have no identity. However, I couldn't even get a piece of red-headed letterhead. If you can't get out of Funiu Mountain, you are drifting blindly; if you are discovered, you are an enemy agent. But he has an AI bionic robot sister from 500 years later, Lin Doubao. She said: Cars can skip the block era and go straight to streamline, communications can skip 1G and go straight to 3G, and the Internet can do without the root servers in the United States. She said: That generation of military workers did not lack hard work, but what they lacked was direction. And she knew the direction. There are still twenty years left before we can achieve the goals of the four modern times by the end of the century. In the past twenty years, he will transform China's technology from a follower to a leader. Let the world see the taillights and be unable to catch up. But the first step is to get the certification letter.
