"My arm..."
Sun Zhuangjia clutched his arm, shouting in disbelief, "This thing is too hard."
"This is too much!"
Seeing Sun Zhuangjia, a Martial General, wounded by striking a rock, Tang Ming and others were taken aback.
"It's useless, I've studied this rock. It should be some kind of meteoric metal, harder than anything on Earth except diamond."
Lin Canghai looked at Sun Zhuangjia getting up from the ground with a strange expression, "If it wasn't like this, I would have blown it open with explosives long ago."
"Damn it, what do we do now? It's like discovering a treasure but not having the key to open it, it's so frustrating."
Meng Xianjun patted the disc unhappily.
"Lin Canghai, can modern science open this place?"
Tang Ming squinted, uncertain, and asked Lin Canghai.
"It should be possible, but special equipment is needed."
