Gao Yang's ultimate goal is to establish a large-scale private military service company.
A truly large PMC Company, even Blackwater's scale would not be enough; it must be at least on par with major companies like Armored Group and Deyang International.
Of course, one has to eat bite by bite; you can't become fat in one gulp. To become a major company, one has to take it step by step. If it's just based on Satan's own strength to start a company from scratch, it is uncertain how many years it would take to reach the scale of Blackwater.
However, if Grand Ivan appears again and still plans to fulfill his promise, then it will be a different story. Just with what Grand Ivan would give to repay the life-saving favor alone, they could arm an ultra-large private military company in minutes, making Gao Yang and his associates one of the giants in the world of PMC.
