Chapter 234 Saint Dias Civilization with a History of Thousands of Years

Regardless of everyone's astonishment, Watson quickly took out a small file from the toolbox and gently filed it on the big black box. Immediately, something darker and brighter like metal pieces would be exposed.

Watson used the gold and silver measuring device to explore for a while and indeed found something new.

But he couldn't speak it out loud, because it was a big golden box.

Not to mention what was inside, just the pure gold alone was enough to determine how precious the thing inside was.

Why did the gold box turn black? Watson guessed that it must have something to do with the sea water's long-term erosion.

Watson took out an X-ray mirror, which was even more exquisite than the microscope. No one could call it a name.

In fact, there were too many tools for Watson to remember, but at least he knew that it was a tool like an X-ray.

The visibility was very good. The perspective mirror could see clearly what was on the surface of this pure gold black box.
