As the drone went deep into the abyss, everyone saw the picture that came back, this is a slender canyon, on both sides of the abyss are dark and rugged rock walls, round black holes can be seen on the rock wall from time to time, from the rules of the circle are artificially excavated, the drone can see one every two hundred meters or so, and the black hole is still spewing white smoke.

The drone continued to go deeper under Lisa's control, and the altitude on the screen had already shown that it was more than 1,600 meters, but the drone had not yet penetrated the dense fog, which really surprised everyone.

It wasn't until the drone descended to nearly minus two kilometers that the dense fog stopped, and a huge open area appeared below, and everyone opened their mouths in shock when they saw the worm valley.

Under the illumination of the drone searchlight, the worm valley is a dense and dark forest that cannot be seen at a glance, and the towering trees are tall beyond imagination, and the forest from time to time emits the long howl of birds of prey, startling the birds to fly out of the forest.

Lisa hurriedly controlled the camera to zoom in, and the camera captured the picture of a bird, and everyone was taken aback, this bird looked a bit like a bat, with open wings at least three meters long, and it was terrifying.

Xiao Man exclaimed: "Is this a pterodactyl?" ”

No one answered Xiaoman's question, and Lisa was suddenly surprised: "The gas detector on the drone detected that the main component of the gas below is nitrogen, with a nitrogen content of more than 98% and only 2% oxygen content!" ”

Dajiu was puzzled: "What do you mean?" ”

Xiaoman answered: "You don't understand this, hillbilly, that is, the gas in the worm valley is not breathable by humans." ”

Dajiu frowned and said, "How is this possible, the sect masters of our Poison Dragon Sect have all practiced Gu in the Worm Valley, and I have also been close to the Worm Valley, so I don't feel that I can't breathe." ”

Luo Hui thought for a while and asked, "Brother Dajiu, did this dark forest originally exist?" ”

Dajiu shook his head blankly: "No, I have never seen this black forest in the Worm Valley, in my memory, the Worm Valley is just a barren land, and there has never been this forest." ”

Luo Hui nodded and said: "That's right, that is to say, the Chiyou organization has transformed the Worm Valley, I don't know if you have found it, these trees are beyond imagination, not like the existing trees on the earth, looking at ......." ”

Xiao Hei answered, "It looks like the demon tree we dealt with just now!" ”

Luo Hui touched Xiao Hei's head and said approvingly: "You look very carefully, it is indeed the same." ”

A few people were talking about the picture sent back by the drone suddenly shook violently, the camera cracked, a huge claw covered the lens of the drone, a big bird attacked the drone, Lisa wanted to control the drone but found it useless, the drone was grabbed by the big bird and fell, and the picture suddenly went black.

Lisa said helplessly: "The drone is dead, but its sacrifice is very valuable, at least we can figure out what the situation is in the Worm Valley, no wonder Zhang Xing reminded us not to go down, he is kind, we really can't just go down rashly, otherwise we will die before we reach the Worm Valley." ”

Everyone was a little puzzled, and Xiao Man asked, "Lisa, you can make your words clearer." ”

Lisa said: "Based on the situation detected by the drone, the worm valley is no longer the worm valley that Dajiu said, it has been transformed into a place with its own ecosystem by the Chiyou organization, and the air below is something that we humans cannot breathe, and the gas that makes these gases is those holes in the rock wall, these fogs are a large amount of nitrogen, and the trees and creatures in the dark forest are not the existing trees and creatures on the earth, they should be demon plants and creatures." ”

Luo Hui said thoughtfully: "That means that the Chiyou organization has simulated the Worm Valley into a world suitable for the living environment of the demon race?" ”

Lisa nodded and said: "That's right, we want to enter the Worm Valley is no less than entering another planet, if we don't have a complete plan, going down is simply sending us to death, if it wasn't for the cat team to stop us from going down just now, maybe we didn't even see the base of the Chiyou organization and died because we couldn't breathe, Zhang Xing's body has been genetically modified, it should be able to breathe below." ”

Da Jiu said with annoyance: "I didn't expect that in such a short period of time, they actually destroyed the Worm Valley of the Poisonous Dragon Sect's forbidden land like this, this is a blasphemy against the Poison Dragon Sect, it's all my fault, I am ashamed of the Sect Masters of the Poisonous Dragon Sect for generations, I ruined my home, why, why did they choose the Worm Valley ......." ”

Luo Hui patted Dajiu's shoulder and said: "Don't be sad Brother Dajiu, I think they chose the worm valley because of the geological conditions of the worm valley, the worm valley is in the hidden rift valley of the mountain, to put it simply, it is in the mountain, generally a space like this is very suitable for forming its own ecological environment, just like some caves in Kunlun Mountain have their own ecosystems, the creatures inside are completely isolated from the outside world, and the form is also free from the earth's creatures. ”

Lisa added: "Team Cats is right, unexplored polar regions like Worm Valley and Kunlun Mountain Caves will look different, and in fact there are many such polar regions on Earth, such as ...... in the darkest world of the ocean. ”

Xiao Man interrupted: "Can we not explore and discover it now, and think about any way to go down." ”

Luo Hui said: "According to the situation in the Worm Valley, we first have to make sure that we can breathe in the Worm Valley, so we have to get a few pairs of oxygen masks and oxygen cylinders, otherwise everything is nonsense." ”

Lisa frowned: "In other words, there is a time limit for our operation this time, and time depends on the reserve of oxygen, once the oxygen is exhausted, regardless of whether the mission is completed or not, we must immediately withdraw from the worm valley, otherwise we will definitely die." ”

Luo Hui stared at the dense fog in the abyss, his mood was extremely heavy, before he came, he expected that this mission would be very arduous, but he didn't expect it to be so arduous, he sighed heavily and said: "Listen to my instructions, retreat to the Cloud Inn first, and then go deep into the Worm Valley when you are fully prepared!" ”

Although Xiaoman was very unwilling, he also knew that what Luo Hui said was right, and everyone turned around, but Dajiu did not follow, but stood there staring at the worm valley in a daze.

Xiao Hei asked: "Uncle Dajiu, let's go, what are you doing in a daze?" ”

Dajiu didn't make a sound, and Lisa frowned and said, "I said Dajiu, don't you want to go down alone?" Do you understand what I was talking about, you know that if the nitrogen content in the air is too high, it will cause the partial pressure of inhaled oxygen to drop, and people will be suffocated by lack of oxygen, this is not a joke! ”
