The reason why he was surprised was mainly because of these walls.
When he came to the main entrance of this research facility, he almost thought that he had returned to Earth because this place looked like one of the high tech research facilities from Earth.
This was an ancient cultivation world where construction technology was still simple. Even using bricks to build houses was considered luxurious and most of the common houses were still built with wood.
So where did they get the technology to learn how to build with metal?
The chimera technology and this research facility, no matter how he looked at it, it seemed like something was off.
It was almost as if they had received technology that they shouldn't own…
But if they did, where had they gotten it?
The more he thought about it, the more he became confused…So in the end, he decided to shake all of this out of his mind and focus on the task at hand.
