The Special Forces Soldier's Path to Immortality

I'll do my best to tell the story of a special forces soldier who transmigrates to the world of cultivation. Long Shengcheng, a soldier king from the Dragon Kingdom on Earth, transmigrates into the body of a sixteen-year-old boy in the cultivation world. From the start, all he has is a spatial bracelet. Using his special abilities, spells, modern knowledge, and military equipment, he embarks on adventures with his female master and senior sisters, traveling between the modern world and the cultivation realm.
