This made Gu Xia Mo truly admire these people.
Perhaps they didn't know it yet, but it was through their accumulation would it be possible for Fei Yang Kingdom to become even better in the future.
Technology had to progress step by step.
And without sufficient people who were knowledgeable enough and willing to experiment, it was impossible for technology to advance.
So even if he came from a world where the technology was a thousand times better, Gu Xia Mo was still full of admiration to the people in this era. Their design was by no means that worse than him as they should have their own concern and methods.
But all in all, the design would definitely last for a long time as long as there was no nuclear bombs or anything like that launched on the site.
Well, it was not something they should concern themselves about.
Gu Xia Mo looked at Song Yun Xiang and asked, "Are you thinking that I should try to make the wall even better and introduce some technology?"
