"Yu Chang is an agent code-named "Yu Yan". This is Wang Kangnian's analysis and judgment." Cao Yu said hurriedly.

Sanbenshi Lang fell into thinking, and he quickly clarified the clues:

The Red Party suspected Cao Yu and deliberately set a trap.

The Red Party deliberately said that Liu Bo's real name is Yu Chang.

They knew that this name would arouse the alertness of the Party Investigation Office, and the government would immediately associate Yu Chang with "Yu Yan".

In this way, Liu Bo was mistaken for being a Red Party ace agent, and the Party Investigation Office would make an extradition request to the French Concession.

Liu Bo is a prisoner serving his sentence in prison. There has never been a precedent for prisoners sentenced in the French Concession to be extradited to the government. Therefore, this abnormal behavior was fed back to the Red Party, and the Red Party immediately judged that Cao Yu leaked Liu Bo's "true identity".

In this way, it confirmed that Liu Bo was an agent of the State Government.

Sanbenzilang had already confirmed the facts in his mind as he had guessed.

At the same time, he also expressed his appreciation for Seto Uchikawa's ability. This subordinate who was also detained in the French Concession Target Field Prison had long analyzed and judged this possibility.

Seeing that Sanbenshi Lang was still thinking, Cao Yu was frightened. He was afraid that the Japanese officer would not believe him and said loudly, "I have evidence, I have evidence."

"What evidence?" asked Sanbenshi Lang.

"Liu Bo admits that he is a 'fish intestine'!" Cao Yu shouted loudly.
