Focusing on the growth and transformation of "Beast Camp War God" Xiang Yu, from his perspective, the bloody journey of the Marine Corps and the secrets of the deep sea are connected. The story starts from Xiang Yu's early experience, showing how he honed his iron will in rigorous training and actual combat - his childhood trauma made him understand early that "only the strong can protect". From a recruit to the "myth of the undefeated beast camp", every time he wins a competition and every time he leads a team on a mission, he is engraved with his ultimate pursuit of military honor. His bond with Instructor Lei, who is both a teacher and a father, and his trust in life and death with his comrades paved the way for his "cold on the outside and hot on the inside" character background, and made the word "guard" the anchor of his life.
