The Ultimate Special Forces King

[Highly recommended new release]

Through relentless, day-and-night physical training, he unexpectedly learns how to enter deep sleep, awakening his body’s super-healing System and immune System. From then on, he soars to greatness, leading the Dragon Soul and Hell squads into parallel worlds, conquering continent after continent, establishing new bases, and plundering resources from other realms.

P.S. A classic recommendation: Return of the Soldier King, by Feng Zhuyue.
