Disintegration Delay

The Eternal City, a fortress city that rose from the ruins after the war, is ruled by the Venus Company. There are hundreds of millions of nanodoctors flowing in residents' bodies - this is a free medical miracle, but it is also an internal bomb that may detonate at any time. Bartender Luo Feng hides in the shadows of this city incognito, hiding a key that can rewrite the fate of the whole city. He just wants to survive until a silver-gray suitcase is sold into the bar where he works. The box contained the Nanodoctor's control unit, which was stolen. Agents of the Anfil Kingdom want to seize it and open the city gates for the next all-out war. The laid-off engineer wants it to buy a chance at life for his daughter in intensive care. The key in Luo Feng's hand is the only one that can be used at the moment before the instruction is executed—— Something that issues an abort command. When the whole city is standing on the edge of the cliff without knowing it, who will press that button?
