[The Grave Robbers' Chronicles + Adventure of the Braves] Return of the Soul

I'm terrible at writing docs _(:з"∠)_ Please don't make suggestions (?˙ー˙?) Walking along the boundary between life and death, lingering between yin and yang. Winter fireflies pierce the open sky, and the brave come and go in a land of magic. Yet the prophet's words speak of immortality; divination is nothing but empty talk. The causes and effects of all things arise from the heart. The Gatekeepers are Shentu and Yulei. The ultimate purpose of all things is immortality. The Five Elements counter one another in an endless cycle, their meaning profound. From the Eight Trigrams comes the Taiji; the Four Symbols are born of the heart. They counter one another in an endless cycle, all for the sake of balance. What the heck (;`O′)o, did I really say all that pretentious stuff above?! I can't keep this up!! Story details: ① The male lead is the next generation Zhang Qiling. In Tomb Raider, he is designed to look 24 ten years later. ② The male lead's real name is unknown, but his code name is Du. He is the star hunter of T.H.A. (the World Treasure Hunters Association), known as Master Du (Little Brother Du). ③ The protagonist has an extraordinary relationship with Shentu. If I had to say, it probably has something to do with his background. ④ One last thing!! → The male lead has a good buddy. If needed, I can bring him out anytime. Finally, a reminder: I've set the Zhang family as a clan with Qilin blood, practically a cheat ability, and a very long lifespan. So if there are any plot holes, please chalk them up to the needs of the story.
