In 1938, Shanghai fell. Under the glitz of the isolated island, the secret war was on the verge of life and death.
Chen Shuo, a warrior whose soul traveled from the future, woke up and became a new agent of the "Special Branch" of the Demon Cave. The memories and beliefs of past lives are immortal, and the souls of party members are burning under the skin of a traitor. With extraordinary intelligence capabilities, proficiency in Japanese and German, and a top-secret static space of only ten cubic meters, he became the "shadow" inserted deep into the enemy's heart.
Under the strict surveillance of the Japanese and puppets, he walked on the edge of the knife:
· Stealing top-secret intelligence: Using space capabilities, confidential documents flow silently in his hands, disrupting enemy searches and conspiracies time and time again.
· Transferring life-saving supplies: In short supply of drugs and huge amounts of money, they have overcome layers of blockades and become the lifeline of the endangered underground party network in Shanghai.
· Dealing with demons: Facing the ruthless and suspicious operations captain Zhang Xiaolin, and the cold and wise Japanese consultant Koichi Takeuchi, he must dance accurately on the tightrope of "reuse" and "observation".
However, a top-secret list of names related to the survival of the underground party pushed him to the cliff. The contact signal sent blindly fell into the sea, and deep in the devil's cave, those cold eyes belonging to Takeuchi focused on him with scrutiny for the first time.
He is the "Shadow", the dark blade on the island.
In the unknown darkness, he used his faith as fire and his loneliness as a blade to guard the city's last light.
One wrong step and you will be doomed.
Can he hold on to this silent sacrifice until dawn?
