The alien invaders, as workers, only need to wear this transparent film and hold this laser cutter to start mining the crimson crystal.
Every time a piece of film is consumed, the cost is minimal, and it is not troublesome because the aliens have strong recovery abilities. If they feel unwell, they can leave in a hurry, and after some time, they can recover on their own, unlike machines that require repairs.
This is why the alien invader leader always uses manual cutting.
"So that's how it is," Lou Fei'Er finally understood, "Then we can destroy the crimson crystal with disposable films and cutting guns for self-defense? How do we destroy it? Cut the crimson crystal into pieces with the cutting gun..."
"Of course not," Xu Xin replied.
The monster provided a method: make small holes in various places of the crimson crystal, then insert small nuclear weapons into them, and detonate them directly after Xu Xin and the others are far away.
