Operation Delta Sons of Asara

Xu Xiaomu's father, Xu Dahai, appeared to be a Chinese aid engineer, but was actually a technical expert secretly dispatched by China to collect technical intelligence on Hafke in the area during the construction of the dam. He carries with him a "technical assistance terminal" - a prototype of the system. After marrying a local woman, he stayed in Assala and died in an "accident" after the dam was built. . . After Xu Dahai's "accidental death", the terminal was left as a relic to the young Xu Xiaomu. Xiaomu always thought it was just a "toy" or "learning machine" left by his father, until the war broke out and when he was dying, the terminal activated the hidden function. Not just a plug-in, but also the last gift his father left for him! Every time the system is upgraded, a piece of father's "legacy information" will be unlocked! Among these messages, there are father's instructions, technical notes, and complicated feelings about the land of Assala!
