Lin Xian didn't dare to do anything these days, fearing that it would affect the world line and cause the loss of Gao Wen, the Time Shuttle Machine, and its engineering blueprints.
In his previous dream entries, he told Gao Wen that the blueprints should be the simplest and most core parts. Other aspects, such as the shape, shell, and energy supply... could be left to the scientists of 2024 to design.
Just like a lighter.
Depending on aesthetic preferences and uses, it can be designed in various forms, but the core structure is the same. As long as the principle is understood, it can be built to produce a flame.
The same is true for computers.
The core components are the CPU, motherboard, memory, hard drive, and others. The actual assembly doesn't affect normal operations and is up to the design factories.
