At the beginning, everything went smoothly, but later his behavior was discovered by his immediate superior, Manager He from the port.

Manager He thought that Liu Changzhou was just taking advantage of others and doing some small smuggling business.

However, when a large amount of wound medicine and some munitions were found in the smuggled goods.

Manager He felt a little uneasy and realized that Liu Changzhou was not simple.

Manager He reported the incident to the police station. However, the officer Li who received the report at the Xicheng Police Station was actually backed by Section Chief Hu Wenlong of the Central Bureau of Investigation.

So, Chief Inspector Li, who suspected that Liu Changzhou might be a Japanese spy or a member of the underground party, informed the Central Bureau of Investigation and Statistics of Liu Changzhou's situation.

There was no suspense about what happened next. After Liu Changzhou was captured by Section Chief Hu Wenlong of the Central Bureau of Investigation and Statistics, he was soon put on the rack.

He endured two hours on the rack, with countless needles piercing his entire body. He felt unbearable pain all over his body and he could no longer bear it!

Liu Changzhou finally couldn't stand the torture and had no choice but to confess the truth, becoming a traitor!

In this way, Hu Wenlong obtained a lot of information about the underground party's "Nightingale" group from Liu Changzhou.

This includes the cover identity of Zhou Jianmin, the leader of the "Nightingale" team, and the location of the "Jimin Pharmacy" where he was hiding.

Later, Hu Wenlong wanted to play the long game and catch the big fish, so he tracked Zhou Jianmin to find other members of the "Nightingale" group.

However, after tracking and monitoring him for a period of time, they found that Zhou Jianmin had no other abnormal behavior and was busy running around in the drugstore all day long.

The Central Bureau of Investigation gradually lost patience with him and was worried that he had discovered their tracking and surveillance, so they decided to arrest Zhou Jianmin immediately.

The Central Bureau of Investigation did not know that Zhou Jianmin did not contact other members of the team very frequently.

If nothing special happens, he may not contact the group members for several weeks.

Moreover, Comrade Zhang Jianglin’s trading company was limited in scale. He had to raise funds through business, and then find ways to buy the scarce and banned goods.

None of these are easy, nor can they be accomplished in a short period of time.

This is why when the Central Bureau of Investigation wanted to arrest Zhou Jianmin of "Jimin Pharmacy", a dangerous intelligence prompt suddenly popped up in Shen Yutang's mind to remind her of the situation.

Zhou Jianmin was not caught, but fortunately Liu Changzhou's identity as a traitor was not exposed.

After Liu Changzhou's health was taken care of for a period of time, his injuries from torture were almost healed.

Hu Wenlong asked him to pretend nothing had happened and continue to work as a foreman at Jiangkou Cargo Port.

Of course, Manager He of the port, who knew the whole incident, was also ordered to keep silent by Hu Wenlong.

It was also because of the arrangement of Manager He that a large number of secret agents from their Central Committee were able to sneak into the port quietly.

It is almost impossible for outsiders to discover that this Jiangkou cargo port has actually been set up as a strict trap!

Using the process of elimination, Shen Yutang could roughly conclude that Liu Changzhou, who was hiding his identity as the foreman of Jiangkou Freight Port, was the traitor of their "Nightingale" group.

For the final identification and anti-espionage operation, Shen Yutang used the "God-level Camouflage" skill he had just acquired.

They dressed themselves up as small businessmen of different ages, genders, and identities, and quietly went to the Jiangkou cargo port to investigate.

When she went there for the first time, posing as a Chinese businessman to inquire about freight prices, a lazy-looking dock loader caught her attention.

[Damn it, when will this underground party member Zhou Jianmin come?! ]

[We guys are exposed to the sun and rain every day at this port dock. When will this end?! ]

[Section Chief Hu and a few team leaders, they stay in Manager He's office all day, they don't have to bask in the sun, and they don't have to work hard to pretend to be loaders. All the hard work is done by us team members. It's really unfair! ]
