From the North City Railway Station, Wen Yichang and Liao Xiuya were safely taken to the safe house prepared for them in advance.

Shen Yutang took off her disguise and told them everything that had happened at the train station before, and told them the strange things in it, letting them judge which link had leaked the information.

"Junior Sister Xiu Ya, I'll be honest with you. When I went to the train station to meet you, I discovered that there were spies from the secret service headquarters inside and outside the station!"

"They are in plain clothes, waiting for you two to arrive in Shanghai by train, so they can arrest you."

"After I discovered something unusual, I killed one of their team leaders, which led them away from the train station. Before he died, that team leader told me personally that you two were the ones I wanted to capture."

Wen Yichang and Liao Xiuya were sent to the Military Intelligence Bureau station in Shanghai to assist her, and the Military Intelligence Bureau headquarters would not tell them that Captain Tang Yan of the Special Agent Headquarters was her cover identity as Shen Yutang.

In order to cover up the fact that Qu Yu had learned the intelligence, Shen Yutang could only say that it was the spy team leader who confessed it before his death.

I heard that their plan to come to the mountain city was exposed in advance!

Wen Yichang and Liao Xiuya were both shocked, and an expression of surprise as if they had just survived a disaster appeared on their faces.

"Sister Shen, if what you said is true, then there is only one possibility for our actions to be exposed."

"I think there must be a traitor at the Military Intelligence Bureau headquarters in our mountain city, and we may have been followed all the way to Shanghai!"

"Otherwise, how could the enemy in Shanghai know our exact arrival time immediately after we set off?!"

Liao Xiuya was indeed an elite female agent trained by Xiang Yingxin. She instantly realized that they might have been targeted by spies sent by the traitors along the way.

Thinking of this, Wen Yichang and Shen Yutang realized something at the same time.

Wen Yichang immediately drew his pistol, walked vigilantly to the window of the room, and carefully looked out at the street downstairs.

"Stationmaster Shen, something seems to be wrong downstairs. People on the street passing by us are looking towards the third floor where we live, intentionally or unintentionally."

"I suspect Lieutenant Liao is right. We must have been followed by someone all the way here. He's even followed us to our safe house. We must evacuate here immediately."

Just as Wen Yichang was carefully standing sideways behind the curtains on the windowsill, observing the street downstairs.

At the same time, a piece of intelligence danger warning popped up in Shen Yutang's mind.

A traitor from the Military Control Commission has been tracking Wen Yichang and Liao Xiuya all the way to your safe house. He immediately sent a telegram to Director Li Liqun of the Special Agents Headquarters via his own radio, informing them to close the net.

If you can't evacuate this place quietly within 1 minute, you will be surrounded by a large number of spies sent by Li Liqun again, and you may die under their random gunfire!

At this moment, Shen Yutang's mind was awakened, and a warning of danger popped up in his mind to remind himself.

It was obvious that the Military Control Commission traitor who had followed Liao Xiuya and Wen Yichang before was not deliberately following Shen Yutang.

Until this time, the traitor used the radio to inform Li Liqun of the secret service headquarters, and several plainclothes agents came to the downstairs of the safe house again, posing a danger to Shen Yutang, and then a danger prompt popped up.

After confirming that there was only 15 minutes left to evacuate, Shen Yutang pulled out a Browning pistol from behind his waist.

"Captain Wen, Junior Sister Xiu Ya, our safe house has definitely been exposed."
