The fight continues, and the monsters with the larger ones don't have the advantage, because there are very few of them, and there are a lot of them with the smaller ones, but they have to work together to kill the other species.

It's not accurate to say that the joint force is combined, because these thousands of monsters are fighting for themselves, and whoever they see will do whom, whoever is close will do whom, no matter whether you are the same species or not, and whether you are big or small, anyway, it is positive and tough, four words can be described, six relatives do not recognize, it can also be said that they will do it when they see it, and they will do who they will do when they see it, and it has to make people wonder whether this group of creatures has primary intelligence.

As time goes on, there are fewer and fewer creatures in the pit of oblivion.

Chu Yu suddenly discovered an extremely strange phenomenon.

That is, the death value of various monsters is at an extremely stable number.

The number of dead and surviving species has reached a certain equilibrium, and even the number of surviving species can be calculated by volume.

For every time a giant with a one-armed chest lay down, five rock-carrying monsters would die in other locations, as well as eight scorpions with snail shells and fifteen crawling creatures covered in carrion, as well as many more small-sized construct species.

It's like a symbiote, if one big one dies, there will definitely be several smaller ones in other areas, and they are not the same species.

After telling Flame Snake and Dracula about the discovery, the three of them began to record it together, trying to confirm whether it was true.

Sure enough, after rough calculations, it was indeed as Chu Yu said, and the results also proved it.

The last to survive were a giant of the largest size, several invertebrates of medium size, and more than a dozen morphic species.

The lucky ones who survived came together from all over the world to fight again.

In the end, to the trio's amazement, these dozens of species actually died together.

There are thousands of species, and not a single living mouth remains, and the odds are even lower than the odds of winning the lottery.

It's not thousands of people fighting, it's species with different abilities and traits fighting each other.

Thousands of ugly-looking monsters died together, and there was not a single living mouth left.

The sound of fighting was gone, the howls were gone, the scalp-tinging sound of flesh and bone tearing was gone, and the silence between heaven and earth was terrifying, leaving only the countless stumps and broken arms in the pit of oblivion.

At this moment, the fog on the other side gradually dissipated, and a ruin appeared in front of the three of them.

Chu Yu, who was holding the telescope, was slightly stunned, and then his face showed a strange color, until after a while, he suddenly gasped, and his eyebrows were full of incredulity.

When Dracula saw Chu Yu's appearance, he also looked at the ruins opposite, and after a while, his face was also extremely strange.

"What's wrong with you two. The flame snake asked inexplicably, "Is there anything strange about the ruins?"

Chu Yu didn't say anything, but Dracula said, "Mohenjo Daro Ruins!"

After finishing, Dracula also looked at Chu Yu with a look of disbelief: "It's Death Hill, right?"

"I don't know, I just thought it was like it, let's take a look. ”

The flame snake was confused: "What the hell is Death Hill?"

Dracula was no longer the same as he used to be, and talked about the so-called ruins of Mohenjo Daro.

In the long history of the surface world, many cities have been destroyed over time, some by disasters and some by war, and the ruins of Mohenjodaro in India are one of them, but how this city of tens of thousands of people was destroyed is still a mystery.

The reason why it is called the Dead Hill Incident is because after it was excavated at that time, there were a large number of wrecks in the city, in addition, the city itself is also very strange, the whole city should have about 100,000 residents, and then all died inexplicably, so it is also called the Dead Hill Incident.

The Death Hill Incident, the Tunguska Explosion, and the Apocalypse Explosion are the famous mysteries of the three natures in the surface world.

In the city of Mohenjo Daro, where about 100,000 inhabitants died inexplicably, archaeologists found traces of violent explosions in the ruins.

Strangely enough, the city existed at least 3,000 years ago, and more than 3,000 years ago, humans simply did not have the ability to create explosives of such power.

The most strange thing is that, according to the understanding of archaeologists and experts, the smelting degree of the ruins at that time was as high as about 1,500 degrees, and this temperature can only be reached by a large explosion, and there is only one explosive that wants to cause this explosion, that is, the atomic bomb, the nuclear explosion!

But the atomic bomb was only invented in World War II, and it could not have appeared more than 3,000 years ago.

In ancient Indian history, there were also legends about a big explosion, all using words such as dazzling light, smokeless fire, silver clouds, and day in the night, and these words basically coincided with the scene of a nuclear explosion.

The center of the ruins explosion has been razed to the ground, and there are bandaging marks that spread outwards from the center, and the farther away you are, the less damage there is, and the edge is almost intact, which is also consistent with the situation of a nuclear explosion.

Including the many remains of bones in the ruins, there is no doubt that the possibility of a nuclear explosion is not confirmed.

It is worth mentioning that archaeologists have found that the city is not only very prosperous, but also quite civilized.

The city has a fairly clear construction plan, which can be said to be very scientific and reasonable in layout, and at the same time has the main characteristics of a modern city.

Such a city with the rudiments of a modern city and a highly developed civilization was suddenly and inexplicably leveled, and it is impossible to figure out what happened at that time.

Bypassing the pit of oblivion, the three of them found a higher position, and after a general observation, Chu Yu and Dracula both determined that it was indeed the ruins of Mohenjo Daro.

Dracula has not been to many places, but there are definitely a lot, it just so happens that the ruins of Mohenjo Darro are one of them, the surface ruins at that time were not as badly destroyed as they are now, when the ruins were just discovered, Dracula also went to see the excitement, so I remember the city.

Chu Yu studied theology and religion overseas, and has an unusually strong interest in supernatural events and mysterious unsolved mysteries, so he has also watched relevant documentaries and materials.

The whole city is rectangular in shape, divided into upper and lower towns, both of which are divided into a checkerboard pattern by vertical and horizontal streets, which run both east-west and north-south, and the streets are very wide.

Residential areas are basically two-storey buildings, with no windows on the street side, presumably to avoid dust and noise.

Each home has a bathroom, toilet and interconnected underground drainage.

Houses are basically arranged with a courtyard in the center and surrounded by living rooms.

Yan Snake didn't understand this aspect, and he was not interested, so after wandering around, he told the two that there were many porcelain, bronze statues, seals and copper plates in the house, which were very well preserved.

In contrast, the ruins here are far better preserved than they were when the surface world was first discovered.

However, there is one thing that is different from the surface world here, and that is that there are no bones here, whereas the surface world does.

In the process of excavating the remains of the surface world, archaeologists at that time found a lot of bones, judging from the posture of the bones, at that time these tens of thousands of people did not know that the disaster was coming, the dinner should be eaten, the wandering of the walk, as well as the bathing party and falling in love, in short, the disaster must have come suddenly, without the slightest warning, this time the disaster, both sudden, and short-lived, after a short time, the whole city became a ruin, and tens of thousands of people all died.

The bones that were exhumed at that time also contained an alarming amount of radiation, which was almost the same as the radiation caused by the atomic bombing during World War II, and there were traces of shock waves and nuclear radiation on the ground.

In short, there is plenty of evidence that nuclear weapons destroyed the city.

But the question is, how could humanity have possessed nuclear weapons 3,000 years ago?

Therefore, the Death Hill incident has always been an unsolved mystery.

The unsolved mystery has always been there, no one has been able to figure it out for hundreds of years, and Chu Yu will naturally not delve into it, what he wants to figure out now is not why this ancient city didn't exist, but why this ancient city appeared here?

Dracula was also thinking about the same thing, muttering, "It shouldn't be the remains of the surface world, because it is too complete, it is the same as the newly excavated, and the remains of the surface world have damaged many areas with the wind and sun." ”

"One ruin underground, one ruin on the surface, the two are basically the same, but the one we see is relatively complete. ”

"Yes, that's what I mean. ”

The three of them walked in silence in the midst of the huge city.

Chu Yu was thinking about things.

Dracula is pretending to be deep.

The Flame Snake didn't understand what it was worth staying in a ruined city with no people.

There are many such cities in the post-apocalyptic wasteland, and there is also no living mouth, there is radiation everywhere, there is nothing to see, and there is no point in exploring.

From the third floor to the fourth floor, I walked past the pile of bones, watched a group of monsters fight, and walked in the ruins city for most of the day, which took more than fifty hours in total.

Yan Snake and Dracula didn't have anything to do, but Chu Yu couldn't hold on, except for sleeping in the lifting platform for a while, he didn't rest.

So the three of them found a relatively clean room and began to take a short rest.

Chu Yu slept for six hours, Dracula also fell asleep, and Yan Snake also rested for a while.

Six hours later, Chu Yu woke up, and after eating something casually, everyone discussed the next step.

The Flame Serpent was going to go to the circular pit of oblivion and pull the corpses to see if those structural monsters really matched the freaks he encountered in the future apocalypse on the surface.

Of course, there's no point in not being sure, and whatever the outcome is, everyone continues all the way west to the next area, or the bottom of the next ladder.

But when the three people who had completed the correction came to the area of the circular oblivion pit, Qi Qi was dumbfounded.

Corpse... Gone, all gone!
