Chapter 638, the essence of the automaton race!

“Boom!”

A humanoid robot with a height of 10 meters carrying a strange beast crashed less than 100 meters away from Yang Tian, causing an explosion.

One of the mech fragments landed less than 10 meters away from Yang Tian.

Yang Tian used his spiritual power to roll this fragment over, holding it in his hand to take a look.

It was a piece of red metal, about the size of a palm. It was thinner than a palm, and it was very light to the touch. It was actually not even one or two layers heavy.

Although it was light, it was extremely hard. Yang Tian used a knife to cut it, leaving a shallow scratch.

It seemed that those huge robots were not as heavy as he had imagined.

Just as Yang Tian was about to throw this piece of metal away, he suddenly realized that it was actually double-layered.

The layer on the surface was extremely thin. Yang Tian used the tip of his knife to scratch it, scraping off the thinnest layer, revealing dense runes.
