Looking for a manwha. He regressed, and to prepare for the monster invasion, invested in finance, while training in gates that were already present. He crew quickly, dropped out of high-school, met a female comrade to join his training. He succeeded in finance by using his previous knowledge, and smoothly took over the world's secret organization with few knowing his real identity. I think his code name was Odin or Zeus (something like that). Thanks in advance.
