Such a huge underground giant city was really beyond Jiang Yan's expectations, and what was even more amazing was the black giant tree that was truly like a pillar of heaven, one thousand meters thick and three thousand meters high, and this was not counting the long roots that dragged Jiang Yan and Xiaobai down from the upper rock and soil before, if it was counted, this height would probably have to be doubled.

In addition, the base of the giant tree must also have roots rooted in the deeper underground beneath the dungeon, and the total height of this giant tree may exceed five thousand meters.

What is the concept of a height of 5,000 meters? You know, the height of some relatively low cumulus clouds is only two or three thousand meters, which means that if the giant tree in front of you grows in the surface area of the planet, then the upper end of its canopy will even go directly to the top of the clouds in the sky, which truly explains what it means to be 'towering into the clouds'!

Although the huge size does not exactly equal strength, it undoubtedly has the advantage of being extremely large.

Jiang Yan didn't have much leisure to feel the majesty of this giant tree, because he found that the black roots wrapped around the surface of the Steel Slime had begun to grab them and fly towards the main trunk of the giant tree, and at the same time, a huge branch with a thickness of nearly 100 meters actually poked out from the main trunk of the giant tree, and at the end of the branch was a bloody mouth that was enough to easily swallow a basketball court, and now the roots that tied the Steel Slime were sending them to that big mouth.

The inner layer of the mouth of the big mouth has a strange dark purple color, and some green oozing mucus is constantly secreted from the skin membrane deep in the mouth, and it has even converged into a small pus-green pond in the depths of the big mouth, and some light smoke can be faintly seen floating on the green pool.

When the big mouth opened, not only Jiang Yan's side, but also the giant tree seemed to have captured some other underground creatures through other roots, and these underground creatures had been bound by the giant tree with their roots and were sending them to that big mouth, and there were at least seven or eight prey caught in the net at one time, and Jiang Yan's side was just one of them.

Jiang Yan didn't want to test which of Xiao Bai's steel mimic defense or the devouring lethality of that big mouth was stronger, he had already sensed a faint sense of threat from the inside of that big mouth, which could bring Jiang Yan a sense of crisis, even if it was relatively light, it already showed that it was at least enough to hurt the threat level of a third-level master.

Facts have proved that Jiang Yan's judgment was correct.

Some of the prey that were also caught, some had already been thrown into the big mouth, Jiang Yan saw it from a distance through Xiaobai's mimic telescope, the poor underground creature after falling into the big mouth, tied its roots and threw it directly into the 'digestive pool' deep in the big mouth, the underground creature immediately struggled with a sad face, but before it fluttered a few times, the whole body and even the belt bones turned into a puddle of viscous turbid liquid in two or three seconds at a speed visible to the naked eye, and slowly sank into the 'digestive pool'.

Jiang Yan felt a chill in his heart, because the strength of that underground creature was not weak, he had scanned it with his ability, it was an elite demonized creature with a second and seventh order, the vitality of the demonized creature was generally extremely tenacious, the physique was strong and had the ability to regenerate and heal, but the other party couldn't hold on for even three seconds after falling into the 'digestive pool' and became boneless.

It can be seen how lethal the 'digester' is.

Even the elite demonized creature that had just been digested, because it lived underground and often dealt with the rocky environment, had a carapace comparable to the hardness of steel on its body like the burrowing giant snail beast, but after falling into the 'digester', it was still melted to the point that there was no scum left!

Some prey with higher intelligence used defensive means such as energy shields built by magic particles before they fell into the 'digestive pool', trying to rely on this to isolate the damage of the 'digestive pool' to themselves, but they were desperate to find that even the defensive shield formed by the magic energy particles was quickly dissolved after touching the 'digestive pool', and the time they could gain during this period was not much different from directly resisting with a carapace.

Obviously, this thing can not only corrupt flesh, blood, bone armor and other substances super quickly, but also has terrifying lethality to energy.

After seeing these lessons from the past, Jiang Yan was really optimistic about the results of Xiaobai falling into the 'digester'.

"Ding, ding, ding......" Suddenly, there was a sudden sound of gold and iron striking from the steel slime's defensive shell.

Jiang Yan scanned his body with his senses, and found that the sound was originally a strange rattan about one meter thick that branched out from the black roots of the giant tree, and the tip of the rattan bloomed like a trumpet flower, and a needle tube with a metallic luster half a meter thick poked out of the flower, and the tinkling sound was produced when the tip of the needle tube was constantly trying to pierce the steel shell of the steel slime.

Although the shell of the Steel Slime was not punctured by the needle, it was poked so that the whole thing was constantly shaking, and Jiang Yan, who was staying inside the Steel Slime, felt that the entire cockpit was constantly trembling, which showed how strong the needle outside was stabbing.

As if sensing Xiaobai's defense, the rattan with the needle no longer poked, and directly pressed the tip of the needle against the steel slime's case, and then a thin hole in the tip of the needle tube flowed out of a light green unknown liquid and fell on the steel shell of the steel slime.

Zizi Zizi......!

In the strange sound, the shell of the Steel Slime was touched by the liquid, and after a few seconds, the shell, which was several points harder than the alloy steel, began to slowly soften and collapse!

It seems that the liquid flowing out of the needle seems to be able to dissolve the defense of the carapace of the prey table?

The shell of the Steel Slime was originally a mimicry of Xiao Bai's body, so Xiao Bai knew better what was going on, and it immediately told Jiang Yan that the liquid could not only dissolve its hard carapace, but also cause a strong paralysis to the flesh and blood body, and the area where it was now stained by the liquid was already a little disobedient.

You must know that Xiaobai not only improved his own strength by devouring a large number of prey, but also absorbed countless innate abilities from his prey, among which there are a lot of resistance innate abilities to abnormal states caused by attacks such as various germs and toxins, and "paralysis resistance" naturally has it. Especially with the "high-speed adaptation", which comes with the natural ability of the race, even if some virus negative damage exceeds its resistance limit, but at least not too much, then it can quickly and automatically adapt to this negative effect, and it is likely to automatically awaken antibodies and increase the corresponding resistance ability.

Since the liquid injected by the giant tree rattan can paralyze even Xiaobai, it means that its effect has exceeded the upper limit that second-level creatures can bear, and has reached a terrifying level that even third-level transcendent creatures cannot be immune.

Looking around, not only Xiaobai, but also some other underground demonized creatures captured by the black roots are also being 'injected' by this strange rattan, they all have two things in common, one of them is relatively strong, and after being captured, they still resist violently trying to break free from the shackles of the black roots, and the other is more prominent, similar to the sturdy turtle shell like the Steel Slime.

It seems that those strange rattans were given 'anesthetic injections' to try to break the resistance of their more difficult prey.

I'm afraid it will really be a little dangerous if I look at it any longer, Jiang Yan immediately ordered Xiaobai to break away from the shackles of the giant tree, of course, not openly.

Because in the air of this huge underground cave space, in addition to the countless roots of the giant tree in the center, there are also countless black iron steel puppets that are constantly cruising back and forth in the sky like bees.

There are three forms of these black steel golems, and Jiang Yan's ability can scan their internal structures, full of steel skeletons, mechanical mechanisms, and energy guides, so it can be determined that they are not flesh and blood creatures, but just machine golems.

One of these black puppets is an insect type, the overall structure is like an enlarged version of the spider, not counting the legs, the body length is more than one meter, larger than the ordinary wild boar on the earth, the spider legs have sharp blades, blood grooves and barbs, at first glance, it is a specially cast structure used to cut and tear the enemy, the hind limbs are very thick, look at the structure should have a good jumping ability, and there is a beetle-like elytra on the back, it is estimated that it should be able to fly.

Many of these arachnid golems climb onto the branching branches and rattans of the giant tree, occasionally crawling back and forth or jumping from branch to branch.

The second kind of puppet is a flying unit, it looks a bit like the form of a falcon, the head and tail are three meters long, the wings on both sides are not soft feathers, but a kind of red light wings, the shape of the light wings looks like a water chestnut, and the tip is like a blade to give people a sense of sharpness, Jiang Yan estimates that this thing can not only fly, but also can be used as an energy sword to play the role of close slashing when necessary; In addition, the head of this eagle-shaped puppet is a little weird, it is directly a simple and rough pointed shape like an awl, Jiang Yan curiously scanned it with his ability and found that it was not a head at all, but a mechanism that can be split and opened at any time, and after opening, a cannon barrel will directly stick out from the inside, obviously this should be a device used to release long-range artillery strikes.

In addition to these two, there is a third type of steel golem on the streets of the city below, shaped like a centaur knight, three meters tall and five meters long, with flexible primate-like hand structures on the arms of the upper body, and each hand holding a half-moon-shaped wide blade with a large door panel, these two wide blades look like seams that can be combined with each other, as long as they are combined, they seem to be a thick shield that can block most of its body. The other centaur puppet also has two long-barreled steel cannons about 80mm caliber on the lower body of the horse, and the barrels are erected just enough to protrude from the waist of the centaur cavalry or rest on its shoulders.

The heads of these three steel golems are equipped with electronic eyes with a cold texture, and they are lit up with an orange-red shimmer, constantly scanning the surroundings as they fly/jump/walk, as if they are inspecting the environment.

How much is it...... Just the data that Jiang Yan counted after a rough scan with his ability, the total number of these three kinds of puppets was at least more than 100,000!

As for combat effectiveness, although Jiang Yan's ability can't scan the data attribute information when facing this kind of artificial puppet creation for the time being, the strength of their power system can be calculated by measuring the energy value of the power furnace in their body, and the combat power of this type of steel puppet creation can often be deduced with the output power of the power system.

Even if the data from this calculation is not accurate, it should not be far off.

Therefore, Jiang Yan can confirm that the average combat power of these 100,000 steel puppets should be in the range of the second level and the first order to the second level five and six orders, among which the energy response in the body of the centaur cavalry puppet is the highest, the falcon puppet is second, and the spider puppet is the weakest.

But even the weakest spider-type puppet, the energy intensity circulating in the energy furnace in a single body is not weaker than the total amount of spiritual power possessed by a second-order and first-order elf. Of course, this is the data that Jiang Yan scanned with his ability, and on the surface, these steel golems do not emit too obvious energy fluctuations.

There were more than 100,000 puppet troops, they were obviously the regular patrol soldiers of this underground giant city, and seeing the appearance of those demonized creatures that occasionally escaped from the roots of the giant trees being ruthlessly attacked, Jiang Yan felt that even if he wanted to escape, it was best to be secretive.

Otherwise, if it is discovered and besieged by these puppet soldiers, it is definitely not a good experience, whether it is the hidden cannon hidden in the body of the falcon puppet or the twin cannon barrels on the back of the centaur cavalry, it is obviously extremely strong long-range fire gathering ability.

Jiang Yan even saw with his own eyes that a demonic creature with a strength of the second and eighth order who resisted too fiercely after being captured was burned by more than a dozen falcon-type puppet soldiers at the same time, and was blasted into meat sauce in two seconds. And this kind of falcon-type puppet cruising in the air, there are tens of thousands, and there are almost no dead ends in this ten-kilometer radius of the underground hollow.

Therefore, Jiang Yan felt that even if he wanted to act, he should keep a low profile.

Xiaobai, who understood Jiang Yan's thoughts, left inside the Steel Slime, once again separated into a small clone, and as soon as this small clone appeared, its figure quickly faded and disappeared into Jiang Yan's vision.

The Steel Slime was quiet, and after more than ten seconds, Xiao Bai behind Jiang Yan screamed at Jiang Yan, and then suddenly grew his mouth, swallowing Jiang Yan, who had no resistance, into his stomach.

Then the size of the white slime, which was more than a meter tall, began to shrink rapidly, shrinking to the size of a fist, then a pebble, and finally a silver data stream and disappeared in a few blink of an eye.

Without being discovered by the giant trees and countless golems outside, the Fullmetal Slime captured by them had escaped silently, leaving only a layer of steel shell that had become empty in place.
