King of Special Forces: Traveling to Temujin, Systematic

Protagonist: Lin Feng (the king of modern special forces, proficient in combat, tactics, reconnaissance, and survival in the wild, with a tough and decisive personality, a strong emphasis on friendship, and modern thinking) - Time Travel Identity: Borjijin Temujin (when he was a boy, about 12-14 years old, his father Yesugei had just been poisoned to death, his tribe was separated, and he was dependent on his mother Hoelun and younger brothers and sisters. He was at a low point in his life) - Goldfinger: - Symbiotic system of all things: Awakening after time travel, the core function is "beast language proficiency" (can communicate with all beasts, tame, form alliances, and obtain intelligence), and comes with "survival assistance" (displaying environmental dangers and resource distribution), "territory construction" (unlocking technology, architectural drawings), and "battle formation deduction" (simulating tactical effects). - To upgrade the system, you need to complete "tribal missions", "survival challenges" and "conquer achievements" to unlock stronger functions (such as "herd call", "weather warning", "cross-race fusion technology", etc.). - World view: an imaginary ancient world that integrates the Mongolian grasslands, Central Asia, Eastern Europe, East Asia, and islands (similar to real history but with a wider geography, including unknown continents and oceans). There are a few "martial arts" settings (such as the "hard skills" and "riding and shooting skills" of tribal warriors, but there is no supernatural internal power, and it focuses more on actual combat).
