There Was No Internet for Large Models in Ancient Times, and Cars Had to Drink Oil.

In 2026, pre-sales engineer Zhou Xing rushed to a remote industrial park to give an on-site demonstration with an offline large-scale model all-in-one machine. After an accident, he and his car fell into a dynasty that had never been recorded in history books. There is no cell phone signal, satellite search is unavailable, and the road has disappeared. All he had left was a damaged plug-in hybrid off-road vehicle, a barrel of gasoline, two solar panels, and an AI that could run without an internet connection. The good news is that large models contain a wealth of modern knowledge. The bad news is - Just because there is an answer doesn't mean it can be created. There is no power grid, no gas station, no standard parts, no after-sales service, and even a suitable screw may not be found. What's even more troublesome is that in this strange dynasty, his first priority is not to change the world. But how to survive first and prove that you are not a refugee, a liar, or a monster in the mountains. As a result, a pre-sales engineer who originally only made plans for customers began the most difficult "on-site delivery" in his life.
