Time passed by, but the secret didn't end. It still lurks endlessly, and it didn't really erupt until thirty years later. It was in 1968, during the War to Resist US Aggression and Aid Vietnam, a talented boy with a distinctive sense of smell was trained as a bomb disposal agent because of his family background and the needs of his motherland, and was sent to Vietnam to fight a Jedi Armageddon with provocative opponents, and staged an intellectual struggle between connection and disconnection, encryption and decryption, assassination and anti-assassination.
This talented boy is Qin Yuan, the grandson of Qin Shuyong. The duel between the two sides involves the family background of this young legend and the amazing secrets hidden behind it. People soon discovered that the original history laid the groundwork for this struggle as early as 30 years ago: Qin Yuan's opponent was actually a "beast" around his grandfather! Behind all this, there are countless obscure relationships: family and state affairs, family and love, personal beliefs and national justice, and the choices of three generations. Finally, it is difficult to tell right from wrong.
The secret has been revealed, but the battle is not over, and the real contest has just begun.
