The helicopter was very narrow, and Bai Song quickly ran to the side of the plane. The rotor of the plane had not been completely closed yet, and it was obviously waiting for orders.

The pilot was from the local rescue agency and was familiar with the police. When he first saw a speedboat, he didn't feel anything special, but when it was about to land, he looked back and found something wrong.

After landing, the pilot immediately reported the incident to the police. Seeing the police's expressions and actions, he knew that this must be a big deal, but watching the doctors rescuing the lying man, he was also a little conflicted.

If he is really entrusted with the investigation, what should this person do?

"Hurry up and send him to the hospital!" Bai Song rushed out and shouted, "The nearest tertiary hospital, hurry!"

Having said that, Bai Song went up to help, and without further ado, prepared to put the person on the plane.

During the one or two minutes of waiting for the plane, the doctor performed a simple treatment on Ji Yue, fixing some parts of her body to a professional stretcher. The previous stretcher had long been discarded.

At the same time, Ji Yue was given emergency medicine, and now Ji Yue was no longer shaking as much.

The back space of the four-seater helicopter is not large, but this stretcher is equipped on the helicopter, and its length is just enough to be put down. The preliminary treatment also allowed Ji Yue to bend his legs to be at the same height as the stretcher, so he successfully entered the cabin and closed the door.

Watching the plane slowly rise into the air and begin to adjust its direction a few dozen meters in the air, Bai Song breathed a sigh of relief and turned to Captain Liu and said, "Let's split up and look for the direction the ship went."

"Okay, we'll send a special police officer to go with you. It's too unsafe for you to go without weapons." Captain Liu came to his senses and made arrangements.

In fact, Captain Liu was a little confused. He clearly felt that his command ability was not up to par.

When Bai Song and others reported the situation an hour ago, Changhe District sent a whole special police squadron. The criminal police squadron came over, led by Deputy Captain Liu, and several departments were on standby at any time, which can be said to be very important.

However, even though Bai Song and others encountered an emergency a few days ago, and Changhe District seemed to have made full preparations for it, it was still far from enough.

The criminal police in the district are organized into brigades, and the serious crime team is organized into squadrons. If Deputy Captain Liu has the same administrative level as Bai Song, he can be considered as the actual on-site commander here.

Captain Liu is already at the level of deputy commander of Bai Song's detachment.

When he first came in, Captain Liu was able to handle the situation with ease when interacting with the man who gave him cigarettes and cards. However, ever since the dog came in and the nail gun started firing, he is now reviewing what happened in the following 20 minutes. He thinks he was indecisive!

This young man who came from a big city and became a leader in his 20s is indeed extraordinary.

Bai Song started the car with Ji Yue's key in his hand. The dogs jumped into the car familiarly. Bai Song took Ren Xu, Wang Liang and a special police officer named Li Dongfang and ran towards the direction of the speedboat.

At this moment, he inexplicably felt a little bit fortunate. Fortunately, there was a helicopter, otherwise he would not know anything about the speedboat. Once they explored to the end of the corridor and found that they had passed through a special channel and left the water, it would waste more than five minutes.

However, when he thought of the helicopter, Bai Song's hands inexplicably tensed up, he stepped on the accelerator to the bottom, and the car sped out.

Along the way, Wang Liang was responsible for planning the route for Bai Song, and Ren Xu was responsible for liaising with other departments.

The information here has just been shared with the Qin Detachment, and the Qin Detachment told Ren Xu that in this rapidly changing situation, he must follow Bai Song's footsteps.

At the same time, Bai Song also shared information with a leader of the plainclothes corps here. Someone had just seen a boat running on the river, and the direction was roughly the same as that seen by the helicopter.

In this basin, the Xiangjiang River has to go down for about 100 kilometers to reach Donghu Lake. Before that, there are usually no tributaries for ships to pass through. If it wants to merge into the Yangtze River, it has to cross the entire Donghu Lake.

In this way, it is actually very easy to chase. After all, it is broad daylight and we can just block it from downstream.

However, there was already a gap of about five minutes, and it was hard to say where exactly it went. The most important thing was that due to the heavy rain in the past few days, the water level of the Xiangjiang River remained high, and many small ditches that usually did not allow ships to pass through were now basically navigable by speedboats.

Captain Liu has already made exploration plans for vehicles from multiple departments, including a plan for the speedboat to travel in the opposite direction of its initial movement.

Bai Song's route is a route with a high probability of spotting ships, but calculations show that even if Bai Song can drive the car at a speed of 70 or 80 kilometers per hour, it will not be easy to catch up.

Bai Song was driving without distraction when he received the latest information from Captain Liu.

After exploring the corridor, there was no one. At the end of the corridor, there was a gate. Preliminary judgment was that this gate was a double door because no water seeped in here.

This double-door structure is similar to the astronauts' extravehicular cabin. Normally, there is air between the two doors. After passing through the first door, you close the door and then open the second door to let water in. When the water pressure returns to normal, you can go out.

The door on the other side of the corridor must be open, so we can't open it rashly here.

"This corridor is about 200 meters long and slopes downward as a whole. The level of building waterproofing is very high, and professionals should be involved. Our branch is preparing to conduct an investigation on companies in this area." When Captain Liu was talking to Bai Song, he did not treat him as an outsider or a child at all, and spoke in great detail.

"More than 200 meters long?" Bai Song slowed down the car. "Does that mean we are in the middle of the river?"

"Yeah, about the same." Captain Liu said as a matter of course: "Although the water depth of the Xiangjiang River has always been relatively stable, the water level is not high during drought years. I guess she is afraid that the underwater objects will leak out or be hit by ships, fishing nets, etc."

"How deep is the Xiangjiang River?" Bai Song asked.

"In this season, this location is relatively narrow, with the middle of the river about 30 meters wide. The deepest part of the Xiangjiang River, the area surrounding the mountains, is 50 to 60 meters wide in the middle of the river, so it is normal that this place has not been discovered." Captain Liu explained.

"More than thirty meters deep!" Bai Song stepped on the brakes.

After listening to Bai Song's words, Captain Liu seemed to understand the key point of the problem all of a sudden.

It's summer, and it just rained. The water is muddy and deep. How did the water come up when the river is so deep?

Swimming up here?

If it is a standard swimming pool 30 meters deep, or in the sea, assuming you are a professional athlete and can try your best to overcome the pressure changes, it is still possible.

But this is a big river!
