The Love of Twins in the Republic of China

In the long history of the Republic of China, a spy war drama intertwined with love and hatred was quietly staged. Two male protagonists with very different personalities but equally talented characters, one is the gentle but hidden edge military intelligence officer Lin Yifeng, the other is the ruthless but deeply affectionate agent killer Yun Wuhen, were reborn in the same era due to an accident, and met because of their common beliefs and missions. In the turbulent political situation and complicated emotional entanglements, they not only have to face numerous tests from the enemy, but also need to unravel the many fogs in each other's hearts and jointly protect the love that transcends life and death.
