Dong Qiang traveled from 2030 to the veterans' resettlement center in 1983. He was not assigned a job and was said to "only know how to fight." He has an extra "spiritual security stick" in his hand - it can release a slight amount of spiritual energy, deter bad guys, and detect dangers around him (abnormal fluctuations in spiritual energy mean there is a problem).
He opened a "Reiki Security Company" in the community, helping people look after stores and patrolling, and also taught residents simple Reiki self-defense techniques (such as using Reiki to strengthen fists). Later, he contracted an orchard on the mountain, used spiritual energy to improve the fruit trees (the fruit was sweeter and resistant to pests), and became a supplier of "reiki fruits". Someone wanted to steal his fruit, but Dong Qiang used the aura of the security stick to keep the other person from coming near (he also used the aura to help the orchard's irrigation system save more water). From unemployed veterans to security guards and orchard bosses, the "Cultivation Security Chart" that pops up occasionally from security sticks suggests that security can be combined with spiritual energy.
