Lin was hesitant to let the army invade the last territory of the Inca swarm, which was the area directly below the desert, but for now, let's study the worms first.

The Purgatory Worm is the largest class of the Inca swarm, and it also spews lava and other attacks, although Lynn calls it lava, but she has never been sure if it is lava or not, it may just be a hot liquid.

And most importantly, what is the origin of the Purgatory Worm? The Purgatory Worm that Lin saw now had apparently been modified by the Inca swarm countless times, and the Purgatory Worm could not be a normal creature, it was slow-moving, huge, and an extremely energy-consuming creature that attacked with a jet of high-temperature solution was only suitable for living in a division of labor.

So Lin is very interested, what kind of creature was the Purgatory Worm in the first place? Was it 'stolen' by the Inca swarm? Or did it evolve from the primitive Inca swarm?

Now, Lynn is about to uncover the secret, and it will be interesting to study these complex and powerful creatures.

First of all, Lynn was most concerned about the Purgatory Worm's body, and the Collector followed the Purgatory Worm's broken body on the ground, and Lynn lit up, and saw the same scene inside as Leviathan when he got inside......

It is like a polished esophageal wall, and it is very long.

The collectors crawled inside, and the deeper they went, the narrower the passage became, and Lynn thought that this passage might run through the entire body of the worm, and the part of the worm buried in the ground may be more than thirty meters, but the body in the underground should not be as wide as the head outside, which is probably the reason why it is difficult for them to get back, and Lin even suspected that they did not have the ability to go backwards.

The collectors made it all the way to the end of the passage. Lynn found a small hole at the end. And the diameter is less than a meter. There are a lot of small particles on the inner walls here, which look like dust.

When the collectors dug through the hole in the worm's tail, they discovered that the surrounding environment was an underground cavern, which was apparently dug by the Purgatory Worms, and that the 'dirt' around the cave had a strange smell.

Nothing special seems to have been found.

Lynn then asked the collector to start digging holes in the wall of the worm's esophagus to see if they could get into it to observe the internal organs and other structures, but it might take a long time because the inner wall of the worm was very tough. The resistance to dissolution is also very strong, and during this time period, Lin plans to study the shell of the Purgatory Worm.

Collectors collected a lot of purgatory worm shell powder under the collapsed homestead tree, and Lynn discovered that it was an extremely special chitin, which is not made by normal sea and terrestrial creatures.

The composition inside is very special, this shell is strong and suitable for resistance to pressure and heat, but it is not the highest in terms of hardness, but the shell of the Purgatory Worm is too thick. Therefore, it is difficult to penetrate through ordinary attacks.

However, Lynn had seen a creature that could make this chitin.

That creature lives under the sea. Lynn hadn't seen it in a long time, but it was also a worm-type creature that usually haunted the depths of lava vents at the bottom of the ocean.

Lynn has a new word to describe these vents: 'volcano'.

Through this, it may be possible to trace the origin of the Purgatory Worm.

Lynn can retrieve information by guò recalling observations at the bottom of the sea......

Most of the creatures will quickly flee when the lava erupts, but some will follow the lava and live after the lava, which are actually quite common, mainly fungi, which like to gather in large numbers in submarine volcanic craters, and when they erupt, a large number of nutrients deep in the formation also erupt, most of these substances are poisonous, but fungi can break them down.

Since there are fungi, there are also organisms that feed on fungi.

Pompeii worms, this is not Lin's name, but a word that comes with it, this small but powerful worm is a large variety of worms that gather near the craters of the sea, some of them live in symbiosis with fungi, some of them feed on fungi.

However, in the face of intermittent eruptions of volcanic lava, fungi can hide in various rock crevices, and the Pompeii worms, which are multicellular creatures, are too large to dodge, so some Pompeii worms have evolved speed, and they can quickly escape from lava.

Others have evolved a 'hard resistance' method, which covers their bodies with a kind of chitinous material to resist the heat of intermittent lava, so that they don't have to travel too far to eat the scalded fungi in the first place.

Where do they get their chitin? Lynn thought it might have been gathered from currents or dug up from the rock near the crater, and Lynn had collected chitin from rocky gravel, but now Lynn had obtained it entirely directly from her prey.

Since this is the case on the seabed, it is clear that there may also be ...... on land Some kind of heat-tolerant creature that lives in intermittent volcanic craters and loves to devour volcanic bacteria.

The origin of the Purgatory Worm may be a very tiny worm-type creature, but after being discovered by the Inca Swarm, the special ability of this creature was quickly used by them, and the Inca Swarm may have used this ability to drill and explore some high-temperature areas, and in the process of development, the Inca Swarm will continue to increase the size of the worm to achieve better results.

Eventually, the original tiny worms became so large that the ability to spray lava may have been incidental, and the Inca swarm likes to use fire, so it is perfect for a class with the ability to resist heat to spit hot liquids.

It should be possible to create a hot substance similar to lava by combining explosives, but in fact, there are many recipes for explosives, and Lynn has only found a few.

Lynn now plans to break down the chitin-making method of the Purgatory Worm, which can be used to explore hot regions, and most of them are fungi that live in hot areas, but occasionally strange creatures can be found.

If you can escape deeper and hotter underground, there will definitely be more spectacular discoveries.

In fact, there are more puzzles, why do the Inca swarms need this worm to burrow into the ground? They like to live in tree cavities, and they are only there to burrow into the ground, they should be about the size of fog worms, why do they make them so huge?

Maybe...... The Inca Swarm has experienced some kind of battlefield before, and it is not certain that the Purgatory Worm is a class born of war.

This is only possible if you have studied the history of the Inca swarm, and I wonder if there is a way to find their history.

That's the next step, march into the territory of the Inca swarm!

At this time, Lynn's collector finally broke open the wall of the esophagus of the Purgatory Worm and burrowed into the Purgatory Worm's body......

In the body of the Purgatory Worm, Lynn saw the unthinkable. (To be continued......)
