The team members around him saw Situ Fang shaking his body and sank, knowing that he must have been injured by the blow from the big fish just now, so they hurriedly went over to help him steady, and saw that the corners of his mouth were oozing some blood, so they gestured to another team member, and took him to open a crack from the fishing net and go up.

A team member named Shao Bin saw that the tiger fish was still biting the flesh of its own kind, so he made a gesture to the fishing net, and after everyone nodded to show that they understood, the four people took off the fishing net, removed the counterweight at the bottom and the bamboo strips on both sides, and slowly leaned towards the tiger fish.

When the distance from the tiger fish was only 50 centimeters, the four people kicked hard under their feet and covered the tiger fish with a net on the body. This time, the tiger fish did not react, and did not choose to retreat after being covered by the fishing net, but struggled against the fishing net, trying to break through the shackles of the fishing net with brute force, the more it was like this, the more conducive to the closure of the fishing net. In the struggle, the fishing net was successfully closed, and after the two of them tightened the fishing net and tied it up, several knives pierced the tigerfish's body from all angles at the same time.

After the tiger fish was stabbed countless times with a diving knife, Shao Bin also learned from Situ Fang and used the knife to cut the belly of the fish together with the fishing net. The tiger fish struggled like this for a few minutes before finally dying.

When the two of them brought the two large tiger fish and the bamboo cage to the boat, Situ Fang was already fine, accompanied by Chen Zhijun, sitting at the table drinking hot water. Seeing that they lifted the tiger fish up, Professor Chen and the others immediately surrounded it, and it looked lively. These two fish are much bigger than yesterday, they are more than a meter long, and the color of their bodies is blue and yellow, and their appearance is different from yesterday's one, they look like a big grass carp. The small tiger fish in the bamboo cage are 20 cm long and the big ones are about 50 centimeters long, and they look different, and there are several different species.

After dealing with the tiger fish, Professor Chen took Situ Fang to play back the video just now, and then said to Situ Fang: "Don't be too risky, if this fish turns around a little more, maybe it won't be able to see you, and you don't need to be injured." ”

After watching the replay, Situ Fang knew how reckless he was just now, and said a little embarrassedly: "Well, thank you Professor for reminding me, I will pay attention if I go down again." ”

"Seeing that you are not in a good state, you can rest for two days first, wait for them to rest for a while, and then let them go into the water, don't worry."

"Let Binzi lead the team, he is much calmer than me."

"Okay, I trust your judgment, you go and communicate, and then you will be by my side and assist me in commanding."

Situ Fang suddenly remembered that there were still some things that needed to be communicated with Professor Chen, so he said: "Professor, there is a problem I need to tell you now, now our camera line and underwater walkie-talkie line boat is not long, after that door, a few meters at most may not be long enough, and if it is directly lengthened like this, it will definitely produce signal attenuation, and this problem needs to be solved." ”

"Oh, Zhang Gong has already considered this problem, he has just asked for the signal amplifier and cable, and he can send it over in a while."

"In addition, the length of the diving knife is relatively short, and if there are any large creatures underwater, I am afraid that it will be difficult to deal with, do you think we can allow us to make our own harpoon or other weapons?"

"Go ashore this night and do it yourself, indeed, if there is a thing as long as a harpoon, it will be much easier to deal with large fish."

After another half an hour, a few people who had rested enough went into the water. After opening the stone door this time, there were no big tigerfish inside, only a few small tigerfish were attracted by the newly put meat in the bamboo cage, and there was no movement behind the door.

When the door was fully opened, the ground was still bare with stones, except for many fish bones and a thick pile of fish droppings. After stepping on the fish feces that were not up to their knees, they walked forward slowly, and after walking a few steps, they found holes at the top of the road in front of them, which were about the same size as estimated, all of them were about 10 centimeters square, and the density was quite high. After walking like this for a few minutes, the length of the line of the camera and the wired walkie-talkie was not enough, and with Professor Chen's authorization, they put down the machine and continued to walk forward for another ten minutes or so. As they walked, they slowly walked out of the water, Shao Bin smelled the air inside, and did not feel anything unusual except for a strong fishy smell.

Shao Bin decisively stopped the team, told everyone to turn around and return to the water, and returned to the boat after taking the camera and walkie-talkie from the corridor. When Professor Chen learned about the situation here, he said excitedly: "I didn't expect it to go so smoothly this time, it seems that I am close to the answer, so let's go down with you in the afternoon!" ”

Situ Fang, who was on the side, heard Professor Chen say that he was going into the water, stood up and hurriedly waved his hand and said, "This is not good!" Professor, it will take about half an hour to get from the boat to the place they said it is, and your constitution will definitely not allow it. ”

"It's okay, won't you leave the water in half an hour, it's nothing."

"Since they are all on the surface of the water, and there is oxygen in it, it means that it is connected to the outside world, so they will definitely be able to find the exit in the afternoon, and tomorrow you will enter through the exit you found, won't it be the same?"

Professor Chen thought about it, and indeed, why bother with this half a day, so he said: "Okay, then this afternoon will work hard for them, and they must find a place to connect with the outside world." ”

At lunchtime, a technician came to install a signal amplifier on the camera and walkie-talkie, and after Zhang Gong's test and acceptance, the effect was not good, and it could not meet their requirements, so they gave up directly. In order to prevent the expedition team from messing around inside, Professor Chen decided to have Chen Zhijun and Lei Tongren follow them inside in the afternoon, and filmed the whole process after coming out of the water. Considering that the front of the tunnel has left the water, if the thickness of the tunnel is not too thick, the attenuation of the radio signal is limited, so Zhang Gong suggested that they bring a few walkie-talkies into it to try to communicate.

After the meal, everyone took a nap to replenish their physical strength, and except for Situ Fang, the remaining 14 people all went into the water with equipment.

After the group walked straight out of the water through the road, they continued to walk for another three minutes, and suddenly the front of them opened up and there was a faint light inside. Shao Bin took the lead and walked a few steps forward and came to the tall stone monument in front of them. Under the strong light of the searchlight, everyone saw this stele clearly, it is about 3 meters high, about 1 meter wide, and it is engraved with the five words "Xiaochu Concubine Garden" in regular script, and there is no time to set up the monument on the side.
