Three Body Fan: Earth Civilization 2:0

Yun Tianming and Ai discovered that the Halo contained the gene pool of the entire earth world, in order to prevent the earth seed from falling into the hands of the Trisolaran extremist organization. So Yun Tianming and Ai Aa built a self-destruct bomb. I'd rather have broken jade than complete tiles. After nearly a year, Yun Tianming and Ai aa built the bomb they wanted. They operated the Halo's nuclear fusion reactor at the lowest power, and then filled the cabin where the reactor was with high explosives. The ignition devices of these explosives were connected to the bracelets on Yun Tianming and Ai aa's hands through wireless signals. The bracelets monitored the pulses of Yun Tianming and Ai aa. If the heartbeat of either Yun Tianming or Ai aa stops, and the other person does not send a termination command within 30 seconds, the bomb will explode. If no signal is received within 30 seconds, the bomb explodes. If either Yun Tianming or Ai AA sends a command to destroy the Halo, it will explode directly in less than 30 seconds. After the explosion of high explosives, the nuclear fusion reactor exploded. Even the Trisolarans could not repair or find any traces of such things.
