(PS: Continue to ask for all kinds of tickets, I try to update, and the tickets depend on everyone.) ）

The underground world is a forbidden area for human beings recorded in many ancient books and history books, and of course, it is also a treasure of resources.

The earliest vague record of the underground world is the most developed and prosperous period of the primeval era, of course, because the primeval era has experienced two and a half major ruins, one is the great rupture at the end of the primeval era, one is the great rupture at the end of the ancient era, and half is the half-scale ruin caused by the human civil war in the ancient sect era, and after the two and a half major ruins, any information in the primeval era is hidden in the fog, so whether the primeval era conquered the underground world, and even whether there was an underground world in that era, so far it is only speculation, and there are still a few records of chasing the wind and shadows。

But what is clear is that the underground world is very vast, and its breadth is no less than that of the ground world, and even more than half of the Chenghai in the seven seas is in the underground world, which is the so-called three-dimensional ocean world, and because of the rich resources of the underground world, whether it is minerals, natural materials and earth treasures, or various levels of creatures, the development of the underground world has not been interrupted, so the information about the underground world is also quite comprehensive.

The underground world is divided into three layers, in fact, in terms of geographical structure, let alone three layers, even thirty layers can be divided, at least so far human beings have not explored the depth and breadth of the underground world at all, and the so-called underground three-layer world is actually determined according to its characteristics and danger.

So far, human exploration has confirmed that the underground layer is the habitat of amphibians, and a small number of level creatures, the amphibians here do not refer to the land and water, but to the underground and the ground, can survive in the two environments, of course, there are also a large number of underground biological characteristics and underground geological environment, but relatively speaking, it is still an environment familiar to humans.

First of all, from the geographical environment, the second layer of the underground has been very unsuitable for human survival, such as high temperature and high pressure environment, such as poisonous gas environment, if these environments can be overcome and recognized, then some extreme environments are beyond human imagination, such as super gravity environment, such as violent plant environment, such as super radiation environment, etc., and at the beginning of the second layer of the underground, the level of creatures is growing geometrically, the more down, the more level creatures, and the stronger the strength, gradually, there will even be a plural number of mad creatures。

But this is still within the tolerance range of human beings, at least not absolute Jedi, but since the third underground layer, all this has completely changed, in the underground three layers, there are many abnormal level creatures, and most of them are extremely powerful mad-level creatures, and there are even traces of violent creatures.

This is only a level creature, the environment of the third layer has more terrifying extremes, for example, according to records, the human expedition team once encountered a fleshy cave in the third layer, everything in that cave has become fleshy, and it is a very terrifying fleshy shape, there are tentacles everywhere, eyes everywhere, teeth everywhere, and all kinds of indescribable tumors and internal organs, at first the expedition people thought it was some kind of fungus creature, or some kind of level creature, but after entering it to investigate, the expedition team found that this was not the case, but all the minerals and stones inside became fleshy in this cave, for example, the precious minerals they obtained from their previous expeditions turned into flesh after entering.

What's even more terrifying is that the clothes and shoes they wear, even their underwear, even their hair and nails, etc., begin to alienate and turn into flesh, and eventually, all the humans who enter them die...... No, that state should not be called death, and perhaps "they" are immortal......

In addition, the historical exploration of the three layers of the underground will encounter all kinds of things that cannot be explained by science, common sense, and internal energy, among which the most famous event is an underground three-layer expedition that occurred in the Red Sea, which is a large-scale exploration group composed of two internal qi realms and more than one hundred and thirty internal force realms, and it is also the early exploration of the development of the Red Empress base, in order to meet the mission materials issued by the Red Empress base, these two internal qi realms and more than one hundred and thirty internal force realms joined forces to enter the three underground layers, and then three months later, only one inner qi realm came back alive, and after returning, he began to destroy everything he sawAnd loudly declared that he had seen God, that God had made him do all this, that he was an apostle, that he wanted to purify the world, and that for some reason, his strength had improved many, much better than three months ago, and he was even close to the edge of God's appearance, that is, God's coverage of 90 percent, and God knows, he only had more than 20 percent of God's coverage when he entered.

It was a catastrophe, a strong person of the Inner Qi Realm of this intensity, even Pan Liuhai, one of the Nine Martial Kings, could not match, to be exact, he would be beaten, but it was only seven days, this crazy Inner Qi Realm powerhouse disappeared in a sound of the completion of the world, if it weren't for the destruction he caused, the destroyed city still existed, he might just be an illusion.

No one knew what this expedition had discovered, what it had encountered, and what could make an inner qi realm with a god coverage rate of more than 20 percent suddenly turn into an extreme powerhouse with a god coverage rate of nearly 90 percent, let alone the so-called "god" Whether it was a certain heavenly treasure, or some kind of creature, or something wrong with the spirit, and no one knew where the inner qi realm ended up going, why it disappeared, and what the voice that appeared out of thin air was, in short, this is the third layer of the earth, known as the forbidden area for humans.

Hao Qi looked at the two level creatures in front of him with an ugly expression, these are two very powerful mad-level creatures, far more than the demon-type mad-level creatures that Hao Qi faced in the Endless Forest, even if Hao Qi came to face it, it was okay to fight one against one, but when facing two, even he would be in danger, and obviously, these were definitely not two ......

In Hao Qi and Lan Ling'er's hearings, there are still many human beings alive in the surrounding darkness, whether it is free blood, or the soldiers of the United States of the Iron Curtain, most of them did not die in the collapse explosion just now, but they will soon regret it, compared to death, the world of the three layers of the underground may be more terrifying...... No, it must be more terrifying!

At a distance of about 100 meters from Hao Qi and the others, a soldier of the United States of the Iron Curtain ejected from the wreckage of the robot, he didn't know where it was before ejecting, and the ejection is an automatic program, unless the pilot reverses the setting from the inside, otherwise the robot is broken to a certain extent, and after the possibility of explosion, then the cockpit will start the ejection program, and the soldier has long been knocked unconscious, he was ejected out of the cockpit without knowing what was happening, and was ejected straight from the cockpit to a height of more than thirty meters, and then the parachute on his back opened, and he began to slowly descend from mid-air, and then...... A tentacle swiped as fast as lightning, wrapping his whole body in the tentacle, and then the soldier let out the most terrifying, loudest roar and pain he had ever been born, but it was only for a second or two, and after more than ten seconds, the tentacle let go, and a pile of skeletons mixed with parachutes was still slowly floating down......

In mid-air, there is a balloon-shaped round life form floating, the shape of this life form is similar to a rounded octopus, dozens of tentacles are waving, each wave will pick up a corpse or a living person from the ground, and then roll in the tentacles for more than ten seconds, and then when it is released, only white bones remain, if you look closely, the tentacles are clearly densely covered with mouths and sharp teeth, small, so many that it makes people's scalp tingle, it is these small ant-like eating mouths that easily eat all the flesh and blood......

Another group of people stood up from the ruins, they were members of the Free Blood Terrorist Organization, and the bunker they were in had completely turned into ruins, and they stood up and tried to figure out where they were, but they couldn't understand it for a while, so they scrambled to get out of the ruins, after all, the ruins were going to be completely destroyed, so they planned to leave the ruins and find another intact fortification.

But when they came out of the ruins, there happened to be a crack in the ground, and from this crack kept spewing gray attempts, like the gas spewing out of a volcanic crater, but everyone who passed by this gas felt that something was wrong, but they could not say anything wrong, and there was no pain or itching in their bodies, so they continued to run forward, and then they ran and ran, and they found that their companions who were running in front of them were getting shorter and smaller...... No, it's not that they're getting shorter and smaller, but they're melting, painless, unconscious, along with flesh, bones, and internal organs, melting into liquid, but the most terrible thing is that even if they melt into liquid, these people seem to be still alive, and the clumps of flesh and blood are condensed together like mud or jelly, and then scattered into the darkness...... (To be continued.) )
