As a result, the ruins of the mountain have become a gladiatorial arena for various forces, and rivers of blood have flowed.

And as more and more elite disciples were lost, the top leaders of those forces realized that there was no winner in this battle, and the gains outweighed the losses.

Therefore, in order to stop this endless struggle, the high-level leaders of countless sect forces jointly set up the "Clear Ruins Trial" after fierce confrontations.

This trial is held once every ten years, once for three years, and each sect sends different numbers of disciples to participate according to their strength.

And in order to prevent some profound sect forces from entering the deeper depths of the ruins and taking the lead, they took countless mountain peaks as points and mountains as lines, and drew a boundary that spread for countless miles, that is, Qingxu Ridge.

Outside of Qingxu Ridge, all sect forces can find opportunities on their own during the trial, but if there are sect elites who dare to enter Qingxu Ridge without authorization and want to get more resources, once discovered, they will be directly killed, and the trial qualification of the force will be directly cancelled.

In addition, it is also stipulated in the trial that large-scale battles are not allowed, otherwise they will be directly disqualified.

It is also not allowed to have sect monks who cross the ranks to kill people and seize treasures, if they are found, they will be killed on the spot, and their sect will directly kick out the qualification to participate in the "Clear Ruins Trial" and will never be allowed to participate.

But the rules are rules, and no one can say whether all sects and forces secretly abide by them.

In fact, because the ruins of the mountain are too vast, every time the "Qingru Trial" begins, the boundary Qingxu Ridge will not advance much farther to the depths of the mountain than the previous limit.

Therefore, the three-year trial time is enough for the children of many forces to turn over the place of trial.

And at the beginning of the trial, the top masters in each force will join forces to hunt down all the third-level demon beasts outside the Qingxu Ridge, leaving only the first- and second-level demon beasts as a means to train the disciples in the sect.

Therefore, the area that has been cleared by the trial will greatly reduce the danger level and become a low-intensity area.

So much so that after the trial, Qingxu Ridge invisibly became a long security cordon.

As for the demon beasts above the third level, they will almost never appear outside the Qingxu Ridge, and if they do appear, it will be a great disaster for the monks who participated in the "Qingxu Trial".

When the demon beast enters the fourth level, it has reached the level of the earth demon, their spiritual intelligence will be greatly improved compared to before, and they already have a tendency to transform, and the overall strength will have a qualitative change, which is extremely terrifying, even if it is the power of some predecessors, they must avoid three points.

Therefore, every time he divides the Qingxu Ridge, he is extremely careful to avoid those dangerous goblin territories.

After the final trial, the cleared low-intensity area will be open to the public, and anyone with the strength can enter it and find resources.

But after being crossed by the locusts of those disciples who participated in the trial, there are still too many resources left, everyone knows very well.

However, after all, it is much safer than before the cleanup, so there are still many monks entering to try their luck.

As for why it takes ten years to start a trial, it is because every time a trial is opened, it requires a lot of manpower and material resources.

Taking the delineation of Qingxu Ridge as an example, this work alone will take several years to properly explore the points and lines that make up the next Qingxu Ridge, which is extremely energy-consuming.

Besides, although there are clear regulations that do not allow large-scale battles between various forces, there are countless crises in the ruins of the mountain itself, and demon beasts are rampant, so when the trial is over, there will be countless children of the forces who will die among them and become the blood food of demon beasts.

This has also led to the fact that the various forces need time to heal their wounds.

That's why this "ruin clearance trial" will only be opened once in ten years.

After a while, Su Chen finally sorted out the relationship between this "Qingxu Trial" and Qingxu Ridge.

But he couldn't figure out that the current Qingxu Ridge was set up a hundred years ago.

At the small dining table, the whole dinner was ready, a large pot of steaming stick bones was the main dish of the evening, and Xiao Ru'er sat on the side, her eyes full of little stars. She didn't know about the content of Su Chen's conversation with Tie Yi, and she didn't have any interest.

Su Chen picked up a stick bone, the fragrance was overflowing, and he took a big bite, and immediately the juice flowed sideways, his lips and teeth were fragrant, and the meat was extremely tender.

After sucking up a drop of meat juice that was about to flow, Su Chen opened his mouth and asked:

"Uncle Tie, this Qingxu Trial starts once every ten years, so why is the current Qingxu Ridge set up a hundred years ago?"

Su Chen couldn't understand a little, according to the time of the "Qingxu Trial", the longest time in this Qingxu Ridge should have been set up ten years ago, why it became a hundred years ago.

Since the python venom has been completely eliminated, Tie Yi's whole person at this moment looks full of energy, and he has the fierceness of a man in the army in every move.

"Engong, don't you know, this ruin trial, as it continues to open, it will go deeper and deeper into the ruins, so the whole trial has become more and more difficult every time, and after the trial a hundred years ago, the entire trial has stopped. ”

Su Chen was a little surprised, "oh", and asked again:

"It's been more than 100 years, has something happened?"

Tie Yi thought for a moment and said:

"It is said that during the last trial, a terrible disaster occurred in the place of trial, countless monks died tragically, and even some of the senior powers in the sect shed blood. ”

Su Chen was frightened, even that great power was bleeding, what kind of horror should have happened.

"So, since that trial, the Qingxu trial has stopped the pendulum and stopped opening. ”

But there are different opinions about what exactly happened, and there is no one exact answer. ”

Tie Yi bit the big stick bone while patiently giving Su Chen an answer.

"Uncle Tie, what is the point of Qingxu Ridge still existing? After all, the trial has been stopped for more than a hundred years. ”

Tie Yi denied Su Chen's idea, and said:

"Actually, since the end of the last trial, the entire Qingxu Ridge has been more closely guarded than before. ”

"Every once in a while, there will be a stronghold guarded by the formation, which will be garrisoned by sect disciples or imperial soldiers, and from time to time there will be great powers patrolling on the Qingxu Ridge, not knowing what they are guarding against. ”

Su Chen was dumbfounded, and the entire Qingxu Ridge was like a fortress forged from a stronghold, dividing the 100,000 Mountains into two parts.

In the end, Tie Yi said earnestly:

"Engong, don't go near the Qingxu Ridge in the future, although there are monks stationed to guard, it is always not safe. ”

For Tie Yi's advice, Su Chen also took it to heart.

After a long conversation, I have a more detailed understanding of these 100,000 mountains and Su Chen.

Outside the Qingxu Ridge, although it is full of danger, there are no demon beasts above the second level, which makes the danger level lower by a notch.

At the same time, the current Qingxu Ridge was set up a hundred years ago, which means that this vast area has been searched countless times by countless monks, and the number of elixirs will definitely drop significantly, which makes Su Chen a little distressed.
