"N5 explosive, a directional tactical nuclear weapon based on the all-nitrogen anion salt compound. High density, high energy, low radiation, and the detonation product is nitrogen gas, making it safe and clean without pollution."
Chen Xuantian squinted,
"No pollution?"
But isn't it unpolluted? It seems like nothing would be left but dust...
A woman's voice coldly said,
"Geiger counter normal, Fifth Team entering the field."
Then Chen Xuantian saw a secret passage opening underground, from which crawled out four metal machines. These were as large as tanks, looking like eight-legged mechanical spiders, with four legs supporting the ground, agilely climbing, and four legs raised overhead, equipped with machine guns, rocket launchers, and missile launchers and other weapon systems.
Four steel spiders crawled out of the sand, surrounded from all sides, approaching Xin Su'er.
