"But this may be a good thing, if the people of the former Yilong era wanted to cultivate to the black level, it would take hundreds of years, and now we can cultivate to this point in decades, and we can proudly say that we are the geniuses of the Yilong clan for millions of years, haha!" The reverse laughter was full of bitterness and helplessness.

The Dragon Clan has been with this space since its birth, and today's Proving Ground is nothing more than the home of the Dragon Artists in ancient times, when there was no second creature in this world except the Dragon Artists, and they lived in a perfect paradise.

Under this space of the Yilong world, the entire Yilong clan reproduced and grew stronger than unimaginable, but a sudden change thousands of years ago completely cut off the living space of the Yilong clan, making them gradually perish.

At that time, no one knew what the reason was, but one day suddenly the heavens and the earth collapsed, the space shattered, and everything in the entire heaven and earth began to collapse, and the vast world before was a hundred times larger than the current testing ground, and the whole world was destroyed in that accident.

The previous space of the Dragon Realm gradually shattered and collapsed, and in the end, only a small part was left and gathered in one place, and finally turned into the internal space of this ancestral mountain, and the other worlds were all destroyed.

After the destruction of the world, the lucky dragon people who stayed in that space survived, and they slowly cultivated and multiplied again with the resources here, and with the large number of people, they began to explore the surrounding world to find the reason for the destruction of the previous world and other survivors.

At that time, people found two exits to leave this space, one of which was the staircase in the center of the main hall that Gu Yue saw when he came in, which were built by later generations, and when these Yilong people went out and found that the entire space was actually inside a mountain, they were also extremely shocked.

When these people wanted to explore the situation outside the mountain, they found that there was a barrier outside the mountain that trapped them, that is, the layer of fog when they entered the mountain, Gu Yue didn't feel much at that time, but as long as the Yilong people entered the fog, their bodies would be eroded by the power inside.

Those fogs seem to be specifically aimed at Yilong people, every time they enter, they will gradually corrode their bodies and energy, and if they stay for a long time, they will gradually lose their minds, and completely become the nourishment of the fog, and become pure energy to replenish it.

The first Yilong people to enter the fog found that when their bodies came into contact with the fog, they would change into scales all over their bodies, and their hands would also turn into sharp claws.

Later, some people thought that they should stay on the mountain to find an opportunity, and gradually figured out the principle of the fog barrier and rushed out to see the situation outside, but others thought that the fog was the end, and there would be nothing outside, so they advocated entering the mountain space from the new to find other exits.

In this way, the few Yilong clans at that time split into two factions, one was stationed on the mountain to explore the principle of the fog and rush out, and the other group returned to the mountain world to find it.

Who knew that later the people in the mountain world had an accident and almost took the lives of all the survivors, and then it was only by relying on the joint efforts of all the Yilong people of the two factions to solve the crisis, but only a small half of the Yilong people survived, and since that time all the Yilong people have moved to the ground, this mountain world is listed in the forbidden area, and ordinary people are not allowed to go at will.

In this way, many years passed, and the Yilong clan produced an amazing genius, and this person has a very bold and adventurous personality, he doesn't listen to anyone's preaching, all the teachers who have taught him have been surpassed by him, and no one can teach him anymore, and he began to play the foggy idea.

At that time, the old patriarch was going to pass on the location to him, but this person was unwilling to accept it, so one morning, he resolutely rushed into the fog alone, although the Yilong clan had a lot of information about this fog, but no one could pass through it.

At that time, people basically knew that these fogs were a phantom killing array, used to trap the ancestral mountain so that they could not get out, and they also knew a lot about the principle, and the genius of the Yilong clan was called "killing the mountain".

After he entered the fog, he used all the information he knew and his strong strength to break out of the fog, and he became the first Yilong person to break out of the fog in so many years.

But when he came to the outside of the mist, he was dumbfounded, because the outside was not as lifeless as the previous legend or what he imagined in his heart, but a new world, a testing ground.

At that time, the trial ground was already a cultivator's world, although it was not as prosperous as it is now, but it could be seen everywhere, and Kill Shan didn't know what was going on, so he could only wander around this world, until later he found another group of surviving Yilong clans.

After learning that there were other survivors, Kill Mountain was very happy, at that time, those Yilong clans were living very miserable, because the current world of the Proving Ground was not suitable for the survival of Yilong people, and the energy they could provide was also very insufficient, so their strength was very low, and they had been fighting with the strength of various cultivators.

In his opinion, only the dragon people are the masters of heaven and earth, and those cultivators should be slaves, so he found the leader of the group of dragons at that time and planned to gather them and all the clansmen on the ancestral mountain to rule the world.

At that time, only the patriarch of the dragon people in the trial ground had just stepped into the black level, and there were not a few red level artists, and the rest were all yellow and white second-level dragon people with average strength, and there were nearly 100 black-level dragon artists on the ancestral mountain, and there were more than 300 red-level dragons, which was enough to level the trial ground and kill all the cultivators at that time.

But those Yilong people have been living in the proving ground for too many years, and their relationship network is very complicated, and there are many entanglements of interests, so when Kill Mountain approached them and said this proposal, an outsider knew about it by coincidence.

Fortunately, the first person to know the news was an elder of the Holy City, and this person was extremely clever and scheming, and after learning of this plan, he mixed in with these dragons and followed them back to their ancestors.

Later, under the stratagery of the elders of this holy city, the Yilong clan broke out in the ancestral mountain, and the battle suffered heavy losses, and in the end, the mage exchanged his life for the result of the Yilong clan's permanent closure of the mountain from contact with the outside world.

It was precisely because of this that the dragon dragon disappeared from the trial ground, and the only person they had contact with was these mages in the Holy City, because the genius elder helped the dragon clan solve a big problem at that time.
