Wu Rui continued next: "As my informant, it is my responsibility to keep your identity confidential, but now the bureau leaders want to approve such a big action. It is not enough to rely on the information I convey. You must have conclusive evidence provided by the director and others to believe it. And deploy the action plan, so you must provide me with some more substantial information."

While listening to Wu Rui's words, Zhang Ze was guessing the situation opposite him.

Wu Rui ran back so recklessly and was eager to save people. He would definitely apply to take action directly when he returned to the team, but the police paid attention to evidence in everything he did. Captain Gao had no investigation and no evidence, so he would definitely not agree.

After arguing, Wu Rui may have gone directly to Director Tong. According to Director Tong's usual behavior, although the father and son were not in the process, he still believed in this son very much.

But he would not be openly helping. He might give Wu Rui a chance to prove himself.

Zhang Ze nodded, praised his brain power, then thought for a while, and said to Wu Rui: "I can provide you with the escape route of this criminal group. That place is very special. If you find it, you will believe what I said is true."

"Okay, you say." Wu Rui took the paper and pen from the side and began to carefully record the address Zhang Ze mentioned.

Director Tong looked at the place Wu Rui wrote on the note, and his brows couldn't help but frown.

How come there is a secret passage in the subway station? This little brat was afraid that someone had been deceived. Director Tong was thinking about how to find a step to stop the matter directly, but suddenly heard Captain Gao exclaim.

"What's wrong?" Director Tong put Wu Rui's note aside and looked at Captain Gao.

When Wu Rui recorded it just now, Captain Gao also recorded the location in his hand. At this time, he looked at the address on the note in his hand and said to the director strangely: "Director, this location is near the terminal of the subway that Ding Yan took."

Director Tong felt a little moved. He also heard about the disappearance of the subway. Therefore, when Captain Gao said that, he immediately thought of some vague possibility.

"Changsheng, you mean..."

"There has always been a difficult point in this case, that is, if Ding Yan is really missing and kidnapped, then how did they take an adult away from the subway station?"

Captain Gao grabbed the white paper on the table, quickly drew a few lines, and pointed to one of the points and said: "This is Xianglinli Station where Ding Yan was missing, and this is the terminal station of Metro No. 2."

He pointed to the lines of the forks: "This is the transfer station along the line. People have sent to check the surveillance points. It can be basically concluded that Ding Yan did not transfer, and Ding Yan got off the bus and left the station along Line 2 was not photographed."

"So our guess is that Ding Yan should have left the station at Xianglinli, and he was also missing here, but we have never found a way for the suspect to take Ding Yan out of the subway."

"If there is a certain passage at this end point as Wu Rui's instructor said, then can we suspect that the suspect took Ding Yan to the last subway, got off at a surveillance blind spot at the end point, and then took Ding Yan into the passage. In this way, he could completely avoid all cameras and complete the crime."

Director Tong frowned and asked, "So do you believe the clues provided by Wu Rui, the so-called informant?"

"I dare not say I believe it." Captain Gao opposed it just now, and it must be a bit embarrassing to change his words suddenly, so he said carefully: "But I am willing to verify it. As long as I can find that channel, I can believe it."

Director Tong nodded silently in his heart. This is great. Since someone supports Wu Rui, there is no need to give up his son's face directly, just let it go.

Before verifying this matter, the fewer people know about it, the better. Therefore, Captain Gao has to take people there in person for this matter, but due to time, it is best for Sister Ying to set up control immediately.

"You don't have enough staff here, so I might as well let the second team and the others..."

Before Director Tong finished his words, Captain Gao hurriedly waved his hand: "No, Director, if this matter is true, the fewer people know, the better. Let's implement it first and make sure, then the thunder action will be captured in one shot."

Director Tong nodded. Indeed, such actions are afraid of leaking the news. The Sister Ying described by Wu Rui is very alert. Once you notice the movement, it is likely to directly destroy the evidence.

"Then how do you arrange these people?" Director Tong asked directly.

Captain Gao thought about it and found that he had too few people under him. Another Wei Ran left. After thinking for a while, he decided to ask Liu Kai and Wu Rui to find a passage. He went to Sister Ying's place to take a look.

"Is it easy for you to come forward?" Captain Gao asked Wu Rui.

Wu Rui thought for a moment, "I can only talk to you on the phone." His biggest concession was his biggest concession.

"Okay." Captain Gao agreed quickly and took out his cell phone and asked for the phone number.

Wu Rui was afraid that Director Tong would hear it, so he turned on his cell phone, called out the phone number and handed it to Captain Gao to see.

Captain Gao squinted his eyes and looked at the number recorded on Wu Rui's phone, and said softly: "Milk...Milk?" He said in confusion: "Female?"

"It's not... the code name." Wu Rui explained awkwardly.

Captain Gao nodded casually: "Well, it's very good. It's not easy to be exposed by the name of relatives."

Wu Rui could only smile awkwardly.

Wu Rui's actions were very fast. In order to save time, he didn't even drive. He directly found the nearest subway station with Liu Kai, took the subway to the terminal station, and showed his identity with the station staff. Then, led by the maintenance workers, entered the subway tunnel.

Because the goal is clear, the range of the passage entrance was quickly locked. It was a waste of civil defense passage.

In fact, there are many facilities in the subway tunnels that people do not know about, such as vertical shafts, precipitation wells, pressure wells, and wind shafts. Some cities will also build civil defense projects together when building subways, which plays an important refuge function when war breaks out or disasters come.

The tunnel where the passage is located is a civil defense engineering channel that was excavated at the beginning of its construction and later was scrapped for various reasons.

The subway staff couldn't explain the reason. Since he came here to work, it has been so abandoned. Originally, isolation doors would be installed outside the civil defense passage, but because it cannot be used here and there is no need to fill it, it was placed here.

Except for occasionally placing rat poison, no one comes here.

Wu Rui called the flashlight provided by the subway station and kept looking in. Then he found the hole on the wall that seemed to collapse naturally.

The entrance of the cave is about half a meter high from the ground. The entrance of the cave is irregularly damaged. There are some sand and soil on the ground, with obviously trampled footprints on it.

Wu Rui looked inside. Sister Ying was very smart. The closer she got to the entrance of the cave, there were almost no lights and there were twists in the cave, so she could not see the light inside.

But it's not difficult to feel, the hole is very deep.
