The End of the Dragon's Journey: Jambu Natan

In 1926, four young people suffered a series of accidents on their way back to China. Relatives and friends died tragically, and the mentor committed suicide. All of this seems to be closely related to the "Sutra-Sealing Tablet" among the mentor's belongings. The four traveled to many places and traveled westward, vowing to uncover the secret behind the "Sutra-Sealing Tablet". Giants in the world, Japanese nobles, eminent monks and great virtues, various factions competed desperately around the sutra board. What is the truth behind a master who is a descendant, a descendant of a royal family, a mysterious armed force, an enemy and a friend? And why did those academic giants who are admired by later generations hide this truth in their writings?
