The so-called formation is actually divided into three classes, namely the flag array, the rune array, and the immortal array.

The flag array, as the name suggests, is based on the array flag, and is arranged in a certain order, combination, etc. by the array mage, and a special aura will be formed within the range of the array flag.

When the formation is completed, the formation flag will disappear with it, and only by attacking the formation eye can the formation flag appear again and then destroy it, and finally be able to break the formation.

The rune array is slightly more advanced than the flag array, and the high-level array mage personally creates a spell that can conjure the formation, and the person who arranges this formation does not necessarily have to be a formation mage, as long as there is a charm.

The immortal array is the most powerful of the three formations, and it is laid by the immortals with the immortal method, this kind of formation has only been recorded in ancient books, and no mortal has seen it with their own eyes.

Of course, Jiang Chao and Tang Ziyan were excepted, because the illusion of the Xuanguang Illusion Yanyan Raccoon that day was actually a formation, and it was at the level of an immortal array.

But no matter which kind of formation, it can be generally divided into three categories, trapped formation, auxiliary formation, and killing formation.

At the beginning, what the Xuanguang Illusory Raccoon performed was one of the trapped arrays, called the Phantom Array, and those who fell into it would escape into the illusion and could not extricate themselves.

At that time, the Xuanguang Illusory Tanuki did not exert all his strength, otherwise, let alone Jiang Chao, even if it was a cultivator in the Mahayana period, he would not want to get out so easily.

Only the legendary immortals who have no self and no desires will be completely immune to the phantom array.

But how can it be so simple to achieve true selflessness and desirelessness, let alone mortals, even if they are immortals, there are few who can achieve such a realm.

And the kind in the Heavenly Thunder Valley is a kind of formation that belongs to the scope of the killing formation, as long as someone enters the formation, it will launch a killing force indiscriminately.

As for the auxiliary formation, as the name suggests, those who are in the formation will get a variety of auxiliary abilities. Some have a big increase in combat power, some have a big increase in defense, and so on and so forth.

Array mages, like alchemists, have an extremely high status among cultivators.

The latter can help cultivators improve their cultivation, treat injuries, etc., while the former can set up their own formations to kill people invisibly, and can also assist cultivators to improve their combat effectiveness and defense, etc.

But it's a pity that the formation has long been lost in this world, although there are still formations in many places in the world, but that is only left by the ancients.

So at this time, when he heard the Earth-Sky Armored Beast say that its owner was a formation mage, Jiang Chao's excitement could be imagined.

If he can learn the formation, maybe he will be able to compete with Lai Hongyi early.

Even if you can't do this, at least you can get an auxiliary formation, and when you face off with Lai Hongyi, you can also increase your attack and defense.

It didn't take long to follow the Earth-Sky Armor Beast before they came to an open field.

The Earth-Sky Armored Beast didn't know how to operate it, and the surroundings that were originally pitch black suddenly became like daylight.

Not only that, but in front of all the beasts, a huge stone gate also appeared, needless to say, it was also known that this stone gate was originally hidden in a formation.

"Go in, my master said, only those who are destined can go in, so I can't accompany you. ”

After the earth-sky armor beast opened the stone door, it turned to look at Jiang Chao and said, "But I want to remind you that there are three tests set by the master here, and only after passing all of them can you get the things inside." ”

"Test?" Jiang Chao frowned slightly, the test set by a formation mage, needless to say, must be related to the formation.

The formation has long been lost, Jiang Chao doesn't even understand it, how can he pass the test?

If it was just a test of the phantom array, then Jiang Chao wouldn't be too worried, but what if it was a real trapped formation or even a killing formation? Jiang Chao wouldn't be able to get out if he didn't go in.

Just when Jiang Chao was hesitating, a flash of inspiration suddenly flashed in his mind, the monk in the chip space, could he also be a formation mage?

Jiang Chao's idea is not groundless.

You must know that this monk single-handedly removed the formation of the Heavenly Thunder Valley, and also made a fake Heavenly Thunder Valley, if he didn't understand the formation, it would be absolutely impossible to do it.

Thinking of this, Jiang Chao immediately asked the monk through his mind.

"Monk, do you understand the formation?"

"Aren't you talking nonsense, if I don't understand the formation, how can I make the Heavenly Thunder Valley what it is now?"

The monk, who was concentrating on cultivation, suddenly puffed up his chest proudly, looking very proud.

Jiang Chao, who received an affirmative reply, suddenly lit up in his eyes: "Great, then I'll trouble you later!"

"What's the trouble for me?" The monk was a little puzzled, could it be that Jiang Chao wanted to let him set up a formation? If that's the case, at least let him go out first, right?

"I don't know yet, I'll tell you when I need to ask you. ”

After Jiang Chao finished speaking, he withdrew from his mind, nodded to the Earth-Sky Armored Beast, and walked towards the stone gate.

"Brother Jiang, be careful. ”

Bai Licheng reminded him with concern, Jiang Chao also thought of it, the formation had long been lost, Jiang Chao rushed in like this, don't really can't get out.

It was at this moment that the Earth-Sky Armored Beast spoke.

"Don't worry, my master once said that if it weren't for the fate, there would be no danger in entering, at most you would be trapped for a while, and then you would come out unharmed. ”

Jiang Chao did not agree with the statement of the earth-sky armored beast, this guy is too unreliable, who knows how long the so-called trapped for a while.

If it's okay for one day or two days, if it's three years and five years, then he won't live, not to mention that the borrowed dantian will be lost, even he himself would have starved to death of thirst a long time ago.

As soon as his feet crossed the stone gate, Jiang Chao felt a flash of white light in front of him, and the next moment he found himself in a vast mountain forest with the fragrance of birds and flowers.

"Illusion?" Jiang Chao didn't have too many surprises, but he was a little curious, and when he entered the illusion, he didn't feel anything abnormal.

In other words, this illusion is no longer an ordinary level illusion, and his physical body has not fallen into it.

Jiang Chao took a closer look and found that the level of this illusion was not weaker than the illusion that the Xuanguang Illusion Raccoon had cast.

However, Jiang Chao was not too worried, Jiang Chao had already experienced this illusion once, and he knew how to crack it.

But just as he was about to crack the illusion, a voice suddenly interrupted his thoughts.

"Chao'er, is this place beautiful?"

Jiang Chao turned to look, and the whole person was instantly stunned, and at the same time, tears flowed out of his eyes.

"Mother..."

Although Jiang Chao knew in his heart that this was just an illusion, his heart was still shocked.

If there is anyone in this world who Jiang Chao misses the most, it is his mother, for nearly ten years, Jiang Chao has never forgotten his mother.
