【Deep Starry Sky-24】

The metal protective shell made by Xin Yan carried them all the way down the body of the giant worm. According to the rough calculation of speed and time, they had already rolled more than 400 meters. But the scrolling still didn't stop.

Xu Yishen resisted the dizziness and said softly, "The body of this bug is longer than I thought, and the gastrointestinal tract in the body is like a labyrinth."

Xin Yan wondered, "Does it have no digestive organs?"

Most advanced animals have a complete digestive system, such as humans. After eating, the food will stay in the stomach first, and the stomach will secrete digestive juice to digest the food initially and then discharge the food into the subsequent intestinal tract. However, this giant worm has no place for food to "stay". After they entered the giant insect's mouth, they kept rolling down.

During the process of rolling down, strange green mucus was secreted continuously, covering the metal protective cover and blocking the transparent viewing window. Xin Yan and Xu Yishen could no longer see the surrounding scene.

Xu Yishen said: "I'll send a replica to take a look." He then used "mitosis" to create two copies of Xu Yishen. The main body was left inside the metal shell, and the replica was placed outside the metal shell.

Unfortunately, Xu Yishen only had time to take a look, and the clone was drowned in weird green slime.

Xu Yi said in deep horror: "This monster's digestive juice is very corrosive, and my clone will be digested very quickly. It is even more terrifying than your strong acid." He paused and looked at Xin Yan seriously: " Its gastric juice itself is acidic, can your strong acid deal with it?

Xin Yan said: "I don't use strong acid, I use white phosphorus."

White phosphorus is a highly flammable chemical substance. Xu Yishen remembered that Xin Yan's skills did have "infinite white phosphorus", and with his "infinite alcohol lamp", he could ignite anytime, anywhere.

Since it is impossible to use acidic liquid to corrode the inside of the monster, using fire is also a good way.

Xu Yishen said: "When I sent the clone out just now, I found that the surrounding tube wall is not the same as what we saw at the beginning, which means that its digestive system changes according to certain rules."

Xin Yan listened carefully: "What do you mean by senior brother?"

Xu Yishen said: "The appearance of this animal is very similar to an annelid. I understand it in terms of the digestive system of an annelid, such as earthworms. The digestive tract includes the mouth, pharynx, esophagus, gizzard, stomach, and intestines. We enter from the mouth and pass through the long The pharynx and esophagus are several hundred meters long, and the location I saw when I went out just now should be the gizzard."

Xin Yan didn't know much about biology, so he nodded and continued to listen to Xu Yishen's analysis.

"The gizzards of annelid animals are well muscled and can grind food. After we entered this area, there was always a sizzling sound like being crushed from the outside of the metal shell. If we replaced it with ordinary creatures, it had already been crushed into powder. "

Xu Yi paused for a while, then suddenly made a bold guess: "This monster's head was electrocuted by Zhuo Feng just now, but it didn't die... Perhaps, it's not its head that we electrocuted, but its tail. ."

Xin Yan was slightly taken aback: "Senior brother, what looks like a head is actually its tail? Its mouthparts grow on its tail?"

Xu Yishen nodded: "Well, it's the exact opposite of ordinary annelids. The mouthparts it uses to swallow are in the tail, and the brain and nerve center responsible for managing actions are buried in the deep pit. Since the brain is not injured, no matter how we hurt it body, it can cut off its tail, split and regenerate."

This kind of alien creature has not been seen before, so I subconsciously thought that the round-looking "head" was its brain.

But since the electric focus failed to kill its "head", it means that this is not its brain!

Xin Yan thought about it carefully and felt that Senior Brother Xu's speculation was very reasonable.

How can an animal have three brains? Will there be no conflict when issuing commands? If it is understood that it has three tails, the tails are shaped like a ball, with eyes, and each has a "mouthpart" that can swallow food. When the tail is injured, it can abandon the body at any time and split into new ones. tail.

And its brain center, which is really responsible for command, is hidden at the bottom of the abyss in the opposite direction.

After Xin Yan wanted to understand this, he immediately said: "We continue to move forward, and what we finally reach is its real brain part?"

Xu Yi nodded deeply and said, "That's right. An annelid's intestine runs from head to tail. As long as we reach its head, we can destroy its nerve center and kill it completely!"

At the same time, Qin Lu held on to the handrail with a pale face. Qin Miao held the light ball given by Senior Brother Zhuo to illuminate it in his left hand. The two of them rolled down the digestive tract all the way.

Qin Miao stretched out her hand and held her sister's fingers tightly. Although they were twins born less than 10 minutes apart, Qin Miao, as an older sister, was used to protecting her younger sister since childhood.

Qin Lu gritted his teeth, looked at the other party and said, "Sister, when will we release the skills?"

If it is released early, the giant worm will continue to split into new life forms, which will be more difficult to deal with. If you are late, you will miss the opportunity. It must reach the "nerve center" of the giant worm in order to give it a fatal blow.

But now, their intestines are crooked, and the metal shell is covered with green mucus, which makes them gradually lose sight of their surroundings. In such a completely enclosed space, constantly rolling down, like rolling into the depths of hell, makes people nervous.

Although Qin Miao was also very nervous, she never showed it. Her expression was still calm, she shook her sister's hand firmly, and said, "Don't worry. We can't see the outside, but we can listen."

Qin Lu said: "You mean, listen to the actions of other groups of students?"

Qin Miao said calmly, "Brother Xu is from the Academy of Biological Sciences and knows more about all kinds of animals than we do. After he enters the gut of this monster, he should be able to quickly analyze the weakness of this thing. Action, we will keep up with it immediately, we can’t go wrong.”

Qin Lu thought for a while, nodded and said, "Okay, then I will freeze the surrounding soil with the 'Siberian Cold Current' to prevent those little bugs from turning the soil and burying us. Burn it!"

Qin Miao said: "Well, get ready. Don't talk, listen carefully to the movement outside."

The two exchanged glances and pricked up their ears to listen to the movement outside.

At this time, the middle passage.

The metal shell where Jiang Pingce and Yue Xingwen were located became more and more turbulent, and there was a violent vibration from outside.

Yue Xingwen simply removed the obstructive plaster that bound his right hand, opened the dictionary with his left hand, and whispered to Jiang Pingce: "I'll put the dictionary's 'fire and burn' skill to burn it to death later. But we are already in the abyss. At the bottom, it's up to you to bring everyone up. You can't see the surroundings, how can you use the coordinate system formula?"

Jiang Pingce said calmly: "Qin Lu will definitely freeze the surrounding area with the Siberian cold current. At that time, the bottom of the abyss will become permafrost, so there is no need to worry about being buried. We can wait for a while and let Xin Yan make a bigger metal. Protective shell, gather everyone together, and then fly up together."

Yue Xingwen nodded and said, "This method is fine. I hope Senior Brother Zhuo can successfully find the ore."

At this moment, after going through 360 degrees of crazy rotation and bumps, the metal protective case suddenly rolled down in one direction.

This seems to be a relatively long and narrow passage that is not tortuous. It is completely different from the winding place just now, and the green mucus secreted around it is also significantly reduced.

Jiang Pingce and Yue Xingwen looked at each other and immediately became alert.

About 5 minutes later, the metal shell that had been rolling suddenly stopped, as if it had reached a gentle area. The next moment, I heard a loud "bang" in my ear, followed by a dazzling fire not far away, obviously Xin Yan ignited a large amount of white phosphorus——

Jiang Pingce said, "It's now!"

Yue Xingwen opened the dictionary without hesitation, and read the idiom aloud: "The fire ignites a prairie!"

The surroundings of the metal shell were instantly swept away by flames!

At the same time, Qin Lu and Qin Miao also began to act. Qin Lu's "Siberian Cold Current" instantly froze the surrounding soil into ice, while Qin Miao's "Fire Company Camp" burned all the way up in the direction she designated!

Three clusters of flames are ignited from different positions one after another, and the time interval is no more than 3 seconds!

The monster was caught off guard by the fire, and its body began to struggle frantically. Under the fierce struggle, it opened its real big mouth and instantly threw the metal shell out!

With a thud, Yue Xingwen's head directly hit the inner wall of the metal shell.

Jiang Pingce hurriedly hugged Yue Xingwen: "Be careful."

Beside them, Xin Yan, Xu Yishen, Qin Lu and Qin Miao were also thrown out, and everyone fell on the frozen soil made by Qin Lu. The metal shell rubbed the frozen soil and made a harsh, high-pitched sound.

At this time, the other students standing at the top of the tall building only saw the bottom of the dark abyss, and a dazzling fire suddenly exploded. Immediately after, the deafening roar of the monster came from the ear!

The little bugs around heard its roar and scattered around in horror.

Lin Manluo hurriedly started the "harmful garbage collection" and put thousands of small bugs into the trash can. Ke Shaobin turned on Xiaotu's "two tigers" monster attracting skills, and let Xiaotu run around the building singing, attracting all the little bugs around.

The rest of the insect swarms that had not had time to be controlled dissipated as quickly as the ebb tide.

Liu Zhaoqing looked at this spectacular scene and felt his scalp tingle: "This giant insect looks badly injured, have Xingwen and the others succeeded?"

Ke Shaobin clenched his fists excitedly: "Look, the fire is getting bigger and bigger!"

The next moment, a cluster of flames shot up into the sky!

Qin Miao's "Burning Camp" can continue to spread. The fire she ignited was mixed with the flames released by Xin Yan and Yue Xingwen.

The giant insect's head was quickly burned, and there was no time to split and regenerate.

Its body as long as several hundred meters has become the best fuse.

In an instant, the giant worm that was clasping its teeth and dancing claws was burned into charcoal by the fire, like three black ropes, unable to wriggle anymore. The three tails that were chasing and biting everyone in the air were like a high-rise building that lost its support. It collapsed instantly and fell into the deep pit!

The fire from the deep pit seemed to burn everything, and it lasted for a long time without going out.

Several people standing on the roof were frightened.

Lin Manluo's face was pale: "I wonder if they are okay?"

Ke Shaobin comforted: "Senior sister, don't worry, the metal cover made by Xin Yan is resistant to high temperature and corrosion, and they won't be able to burn them in just a few minutes of fire."

In theory, they will be fine if they stay in the protective cover made by Xin Yan and have sufficient oxygen.

But Lin Manluo couldn't help but worry. She clenched her fists tightly and whispered, "It's been 5 minutes, this giant worm should have been burned to death, why haven't they come up yet?"
