With the investigation coming this far, Long Yuehong and the others gradually had an idea of the ins and outs.
Two people in the Salvation Army's secret base—who had access to the nuclear warhead—had been instigated to defect for some reason. They seized the opportunity to bring the corresponding items to Ubei. They then completed the transaction with their contact and handed over the nuclear warhead, obtaining a large amount of supplies and a route out of the Salvation Army.
After separating from their contact, the two defectors headed west. In the end, they were discovered near a settlement closest to Cloud Mountain before being killed. The person who obtained the nuclear bomb handed the weapon of mass destruction to a relatively strong person, or he himself was strong.
