In this continent, the formations involve all aspects, from the additional formations such as fire, weight gain, lightness, tenacity, etc., engraved on weapons and equipment, to the trapped and killing arrays arranged by spirit stones, and even the imaging arrays, lighting arrays, and acceleration formations that can be used by ordinary people......

The formation needs a formation map, and some complex formations also need spirit stones and formation disks. However, most of the formation depictions require spiritual power, otherwise there is no way to continue, so most of the formation masters themselves are cultivators.

Li Yuanhong was not a cultivator, and it was already a mystery how he entered the formation system to study at that time, but his attainments in the formation surpassed many cultivators.

The reason is that his understanding of formation is far beyond that of ordinary formation masters. He really became famous in a battle between the Moon Country and the Western Grassland Country one hundred and seventy years ago. The two countries have been at war countless times for hundreds of years, and every few decades there is a customary war, and in that war, the important city of Yincheng, on the western border of the Moon Country, has fallen imminently.

Once Yincheng fell, thousands of miles on the western border of the Moon Kingdom would be almost undefended against the grassland light cavalry that came and went like the wind. Naturally, the Moon Kingdom understood this and continued to increase its troops, but after several months of meat grinder-like offensive and defensive battles, Yincheng finally fell.

At that time, Li Yuanhong was just an unknown auxiliary formation mage with the army, and he was not even a formal formation mage when he was in his forties, and some of his theories on the formation were not taken seriously.

After the steppe people occupied this city, he was also expelled by the steppe people's light cavalry and followed the remnants of the Moon Kingdom to the hinterland of the Moon Country. And that night, the afterglow of the main force of more than 100,000 grassland people celebrating the capture of Yincheng had not stopped, and this border city suddenly turned into a sea of fire.

According to the memories of the soldiers of the Moon Kingdom behind the palace at that time, all the silver cities within a radius of more than ten miles were filled with raging fires, and almost all the sky was shrouded in fires, and the scorching heat could be felt for dozens of miles nearby, almost making people think that the end was coming.

The fire burned for three days and two nights before it gradually stopped, and none of the more than 100,000 elite grassland people, including cultivators, survived. Their bodies have long been found, because even the buildings in the city have been burned down, not to mention the ** of people.

After this battle, the offensive of the grassland people came to an abrupt end, and the disappearance of hundreds of thousands of elites even made the grassland country almost collapse.

After the battle, there was a lot of speculation about the sudden fire, and at first many thought that the grassland people were celebrating too much and accidentally caught fire. But it soon turned out that this couldn't be explained at all, as a border city, most of the buildings in Yincheng were made of stone, even if there was a fire, how could it instantly cause a fire that spread for more than ten miles, and even cultivators could not escape?

Subsequently, after countless speculations and overturning speculations, people's eyes gradually turned to the formation. Prior to this, the formation had flourished in the Cangluo Continent, affecting all aspects of people's lives, and if it weren't for this, the formation master would not have been brought with him. But there has never been a formation that can achieve such a large scale and produce such a powerful ruining effect.

In the past, the main role of the mages in the army was generally reflected in the small battles to arrange some small trapped formations, or dozens or hundreds of formation mages to arrange a large killing formation, but this formation was generally only for ordinary soldiers to cause a large number of casualties.

Even if dozens of formation mages joined forces to arrange a similar incineration formation, it would only cover a radius of a few miles at most, and it would not be difficult for cultivators to escape. The reason is that the larger the area covered by the formation, the more complex the lines of the formation diagram, a formation covering a radius of one mile has thousands of formation nodes, and the lines are even more intricate, which cannot be completed by a single person at all.

And the more complex the line, the more likely it is that something will go wrong. The position of a certain node is wrong, and the interaction between certain lines may cause the formation to fail or even collapse.

At the same time, the more powerful the formation...... The more spirit stones you put in, the more you need to invest!

The formation covering more than ten miles, people can't imagine how complex the formation diagram is, this is simply not something that can be drawn by manpower, and can only be stored in theory. And such a huge project, the defenders of the Moon Kingdom at that time didn't even know about it.

Even if hundreds of array mages were able to arrange a Heavenly Fire Array covering a radius of dozens of miles, they couldn't imagine how they could burn all the cultivators above the Extreme Realm inside.

It is for this reason that people did not associate the fire with the formation in the first place.

Afterwards, there was a military mage who took the credit for it, but it was quickly exposed, because the person who could arrange such a formation has undoubtedly become a strategic-level "national treasure" of the Moon Country, and whether there is such a talent will soon be revealed once it is tested.

Li Yuanhong was not discovered at first, because he was only an extremely inconspicuous member of the mages in the military formation, and he himself did not seem to have any intention of taking the initiative to clarify the facts. However, as the official investigation of the Moon Kingdom continued to deepen, some of his abnormal actions in the days before the fall of Yincheng were gradually discovered.

After confirming his feat, the then king of the Moon Kingdom rushed to the border from the royal capital, took him back to the royal capital, and personally drove him for several miles. Countless array mages on the continent rushed to the Moon Kingdom from their respective countries, sects, and academies, just to be able to receive his guidance.

Of course, there are countless people who want to kill him. For example, the Grassland Country, the Qingchuan Country, and the Southern Qi Country are countries bordering the Moon Country. It's just that in the face of the strict protection of the Moon Kingdom, these forces have no gaps, and the strength of the guards sent to Li Yuanhong by the Moon Kingdom at that time is even comparable to the guardian of the King of the Moon Kingdom.

For a while, it seemed that because of his birth, the pattern of war on the entire continent would be changed.

Some of Li Yuanhong's previous anecdotes were gradually unearthed, including that he was not a cultivator, including that he had visited the trial room of Shengyun Academy when he was a student at Shengyun Academy.

He later presided over the construction of the Moon King's defensive formation, which was even more magnificent than the Heavenly Fire Array in Silver City, and this formation also made it nearly impossible for the Moon King to be captured.

But Li Yuanhong later seemed to gradually disappear from people's sight, and many of his formation theories were circulated, but no one could copy the two large arrays he had arranged.

After that, although the war on the mainland was more valued, there was no way to turn the tide of a war like Li Yuanhong.

But no matter what, he was the only one recognized as a formation grandmaster on the mainland.

Since it was him, then it would be reasonable for a cultivator to go through the guò trial room. After all, although the trials in the trial room are extremely perverted, their own strength is not enough to hold on. But these trials are still composed and driven by formations, Li Yuanhong doesn't need to break through the levels head-on, he only needs to break the formations one by one to make the trial devices in the trial hall fail.

Unlike other academies that rely on their own strength to resist the formation, Li Yuanhong is a real breaking formation......

The reason why the academy later allowed ordinary students to enter the trial room was to commemorate this formation master, and on the other hand, it also wanted to discover a formation genius again.

It's just that although Li Yuanhong's actions to break the formation are simple to say, no one can do it anymore. The reason for this is that many formations in the trial room need to be broken continuously in a very short time, otherwise the attack will still fall on people.

How could the array mage be disturbed when he was concentrating on breaking the formation, and even an attack containing spiritual power. Therefore, ordinary students who enter the trial room will either be quickly beaten out by resisting head-on, or they will be knocked down before they have time to check the formation, let alone break the formation. Except for Li Yuanhong, only the senior leaders in the cultivation department who have been able to open this trial hall for hundreds of years have been able to get through.

Although it is incredible for Li Yuanhong to do this, no one questions him because he is Li Yuanhong.

Lin Si didn't know about Li Yuanhong, and even if he knew, he would at most just express his admiration in his heart.

As for the formation, he just heard its name and didn't know what it meant, and since he came out of the forest, he hadn't come into contact with such a profound thing. He just looked at the administrator opposite, with a helpless expression.

The administrator was expressionless and ignored him.

He didn't say a word, ordinary students entering this venue were just a waste of time, and setting a thousand-point entry condition was just to make those ordinary students who couldn't help themselves retreat.

But Rao is like this, every year, there are still many ordinary students who don't know the height of the sky, and every year they have saved enough credits to challenge here, but in the end, they all hit their heads and bleed.

Seeing that there was no hope, Lin Si planned to leave directly, but when he thought of going back like this, he was faced with Mu Zheping's already expected expression, and he was unconvinced for a while......

So he turned his head and walked towards the other one-man trial room.

Guan Ning and Liang Chunan had been paying attention to Lin Si, and they couldn't help but be surprised when they saw him leave the trial room and head towards another venue.

They had thought that Lin Si might be an ordinary student, and they had thought that soon after he entered the trial room, he would be beaten out by the formation inside.

I even wondered if this person could really hold out for a long time if he was deeply hidden, but the only thing he didn't expect was that this person left directly after talking to the administrator and then went to the next venue.

There are nearly 1,000 students in the Holy Cloud Cultivation Department, and there are naturally several trial rooms, otherwise how can only one be arranged.

But it was the weekend, and there weren't many people using it, and the door to the trial room didn't show that it was occupied......

"Huh...... It's another person who doesn't know the situation, it must be that the credits are not enough!" The senior on the side naturally also noticed Lin Si, and his tone was slightly mocking.

Guan Ning and the others couldn't help but be stunned for a while, their cultivation department only needed a hundred credits to enter it, and the cultivation department was much easier to accumulate credits than ordinary departments, so they really didn't think of this section.

If it's just that the credits are not enough to enter, then he should just give up and leave, why go to the next one, isn't there no need for credits in the next one?

It was only after watching Lin Si be stopped again at the door of the next trial room, and then after talking a few words, he left and went to the next trial hall inside, that they believed this speculation.

It's just that this student is really persistent enough, does he expect to impress the "iron-faced and selfless" administrator like this? Seeing him try one by one, it doesn't look like he's coming to test, but like he's looking for someone.

Lin Si's heart was naturally extremely depressed, he actually understood that it was useless for him to try it out like this now, but he had a trace of luck, but no matter how softly he begged, the administrator of the trial room never said anything. At most, he waved his hand impatiently at him and let him go like a fly.

Gradually, he walked into the depths, and before he knew it, he had reached the end of this cultivation hall, and there was no one inside. Turning through a long corridor, he was greeted by a trial room, but his eyes lit up.

Because there was no one guarding the entrance of this trial hall.

No one guards means no one checks the ID badge, so credits or anything is not a problem.

Lin Si is not a person who divides An'an, otherwise he would not have used the method of stealing medicine to make others ashamed when Xiaoyun was sick.

Now, naturally, he is planning to break in...... xh118
