After about half a minute, Professor Wang Zhi finished sampling. In fact, he took a few leaves, fruits, and canes, and put them into plastic bags and sealed them up.Only Professor Wang Zhi can do this. In comparison, Erdan Li and Big Brother Wang Lin are both masters with great nerves.

Wang Lin turned on the flashlight twice with an interval of five seconds.When the people above received the signal, they started to lower the rope again, but at a slower speed.

As Wang Lin said, the further you go down, the bigger the cave space is, and the more it bends, the density of dead and unknown plants climbing on the cave wall is gradually increasing.

When they descended to a depth of 250 meters and crossed the big turning point above, the rope rubbed against the turning point, and the three of them became suspended again, and another scene appeared in front of them.At this time, the speed of the rope lowering was very slow, and they could better look at everything in the hole after the turning point.

"Damn it, there are too many plants here, it's almost blocking the hole." Er Dan exclaimed.

It’s not a big deal, looking down, the dense dead plants not only covered the cave wall, but also crossed each other and grew up, scrambling to grow up, almost filling the huge hole.Erdan even suspected that if he just jumped down like this, the dense nameless rattan plants would be able to bear his weight.Of course, Erdan was just thinking about it, and he would never jump down, because the dead plants seemed dense, but they were actually very weak, and could be broken into dross with just a pinch.Perhaps, as Professor Wang Zhi said just now, the unknown plant was infected by an unknown virus, not only killed itself, but also killed the strange and abnormal Lop Nur virus.In addition, the weird and eerie atmosphere here is even stronger, almost depressing, and the temperature is seriously cold.

At this place, Wang Lin flashed the flashlight three times in a row to tell his subordinates to stop releasing the rope.

An inescapable problem before everyone is how to find a small hole on the wall of the cave that is tightly covered by unknown plants.What's more, if you go further, people enter the dense vegetation area, and the communication with the people above will be interrupted, because the flashlight light will be blocked by the dense vegetation.If the people above couldn't receive the signal, they would just keep lowering the rope, and even put down the kilometer-long rope all the time.

The place with a depth of 300 meters in the Big Ear Eyes Bottomless Abyss has been reached by expedition members before, but it is not what it is now. The unknown plants at that time were not dead, they were dark and shiny, and seemed to have infinite vitality, and they were not as dense as they are now. It is easy to go down by hanging on the rope.On the cave wall at this depth, there used to be several small caves. After entering the cave, it seems to be in an unknown world.

Wang Lin disregarded the high-level prohibition, and led Er Dan and Wang Zhi into the bottomless abyss of big ears and eyes without authorization. He would never shrink back when encountering the slightest difficulty. Moreover, everyone has not encountered any difficulties so far.Therefore, even if there are dead and nameless plants that almost block the cave in front of him, and he can't pass information to the people above after going deep, Wang Lin will retreat back, because this time he came with a lot of determination and didn't accept it. Buy some good things, sorry for the compatriots who died because of Lop Nur!

Now, the three descended from a depth of 200 meters to a depth of 250 meters, but they didn't find a small cave wall.This is enough to show that the topography of the big ear has changed, and even the bottomless abyss has also changed.Then, the supernatural fortifications under [-] meters may have also changed.

Wang Lin looked at Professor Wang Zhi and said, "Professor Wang, it's up to you. I remember you have an ultrasonic detector on you."

Professor Wang Zhi nodded, and said with a smile: "I said that bringing more instruments will always come in handy. You and Er Dan still don't believe me. Fortunately, I didn't listen to you, otherwise we would have to turn on blind lights in vain. With that said, he put his back close to Big Brother Wang Lin, and said, "Please take out the ultrasonic detector from inside."

Ultrasonic detectors use ultrasonic waves to detect objects, which can be used for positioning, distance measurement, and speed measurement.Some birds and animals detect and locate objects by emitting ultrasonic waves.If there is a small hole on the wall of the cave, if the ultrasonic waves are emitted towards it, there will be no return, and thus the existence of the hole can be detected.

Wang Lin took out the portable ultrasonic detector from Wang Zhi's backpack, handed it to Wang Zhi, and said, "Quickly try to see if the ultrasonic detector inside works well."

There is an unknown power in the bottomless abyss with big ears and eyes, which can block all kinds of signals, so Wang Lin's suspicion is still very reasonable.

After Wang Zhi turned on the ultrasonic detector, he fired it at the cave wall. Almost at the same time, the detector displayed a value, the distance from the emission point to the cave wall.Although there are plants blocking the way, the ultrasonic waves have strong penetrating power and can easily penetrate the plants, reach the cave wall, and then reflect back.

"It can be used." Professor Wang Zhi said with a little excitement.

The rope that suspended the three people was then lowered, and the three people also entered the densely packed dead unknown plants.Although the nameless plants are dense, they are extremely dead, as if they have been dead for hundreds of years. They are so brittle that they will break if you step on them.This is not the point, the point is that the powder flakes formed after the dead plants are trampled are very annoying, not to mention the charming eyes, the skin will itch when it comes into contact with the skin, and small bumps will form when you scratch it with your hands.The three of them were covered tightly from head to toe, except for the exposed face and neck.As a result, their faces and necks suffered, itchy, stinging, red and itchy.If it goes on like this, their faces and necks will have to be scratched.Of course, this little problem is easy to solve. They cut a large cloth off their bodies with sabers and covered their faces, so they don't have to worry about coming into contact with powder dust.

Professor Wang Zhi kept scanning the cave wall with an ultrasonic detector from a depth of 250 meters to a depth of 300 meters, but he didn't find a small hole in the cave wall.Perhaps, there is indeed no small hole in the cave wall, perhaps the ultrasonic detector did not detect it.

Now the three of them have completely lost contact with the top. The people above don't know the situation below, and there is no flashlight signal to stop, so they will keep lowering the rope at the current speed until the end of the kilometer.

Suddenly, a few minutes passed, and now the three of them came to the cave depth of 400 meters.Similarly, the detector in Professor Wang Zhi's hand still failed to detect a small hole on the wall of the cave.This made Erdan have to wonder if the ultrasonic detector in his hand was not working well.
