The interior of the metal fragment was extremely vast, and he felt extremely small within it.
Tang Zhen sized up his surroundings and discovered that the area around the entrance had been severely damaged. There were many signs of violent demolition.
Picking up a thin piece of metal from the metal floor, Tang Zhen discovered that it was very light and extremely tough.
Even though it had been buried in the soil for many years, it still looked as good as new!
He wondered what kind of effect it would have if it was used to make weapons.
Tang Zhen picked up some more metal from the ground and kept it in his storage space. He was prepared to hand it over to furnace hammer for him to study it in detail.
Tang Zhen was hesitating if he should continue to go deeper as he looked at the tunnel that was slanted downwards.
Tang Zhen had basically confirmed that the metal bomb's origin came from this metal wreckage.
