After the 6.1-magnitude earthquake on the Korean Peninsula, the No. 1 Atomic Power Plant in Busan exploded, and the nuclear power plant fell into crisis. The explosion caused by the large-scale earthquake caused cracks in the nuclear power plant, and a radioactive material leak occurred. The disaster without warning has caused chaos and panic on the Korean Peninsula. Even the tower, which has always believed that it can warn of disasters, is on the verge of collapse. The terror of nuclear leakage is gradually sweeping in, and it may even trigger a second explosion. Nuclear power plant workers, residents, and firefighters launched disaster relief operations, but the threat of the next round of explosions has already arrived.
