The compound formation is the most difficult to crack, but the compound formation is extremely complicated, and there is no way to arrange the compound formation if you are not proficient in the formation and have great magical powers!

The first and most important step in arranging the formation is to engrave the formation!

Once the formation pattern is successfully inscribed, then it cannot be changed again, unless it is completely reversed - that is, the formation pattern you engraved is a phantom array, and if you want to superimpose this phantom array into the upper killing array, then you must re-engrave the formation.

The composite formation is actually a comprehensive formation of several different formations, superimposed, and blended together, each of which plays a different role.

On the Hanging Mountain, there is a compound formation, which Zhou Zhirou knew when she was very young.

It was arranged by her grandfather himself, and it can be called a powerful and unpredictable one, and it is a number of phantom arrays mixed with killing arrays, teleportation arrays, trap arrays, and so on.

In Zhou Zhirou's impression, grandpa always looks calm and unfazed, and the only time I saw him who was very excited and excited was when he told her about the incomparably complex composite formation.

"No matter how clever this formation is, it won't be better than the formation on the Hanging Mountain, right?"

Zhou Zhirou thought to herself, and she walked along the front of the corridor.

Along the way, she was cautious and very careful to feel the changes in the vitality of the surrounding heaven and earth.

The inscription of the formation pattern is not casual, but needs to be carved according to the surrounding environment in accordance with the general trend of heaven and earth. The most important point of this is that the surrounding Heaven and Earth Yuan Qi must be strong, and only a very strong Heaven and Earth Yuan Qi can ensure the operation of the formation.

For the formation, the Heaven and Earth Yuan Qi is energy, if there is not enough Heaven and Earth Yuan Qi, even if the formation pattern is inscribed, it will not be able to promote the formation.

Therefore, for those who are familiar with the formation, from the fluctuations of the surrounding heaven and earth vitality, they can roughly judge the changes in this formation.

This promenade doesn't look long. It's only about two or three hundred meters.

Along the way, there was no danger, and it was very smooth to the exit of this corridor.

But after standing at the exit of the corridor, Zhou Zhirou found that there was an identical corridor in front of her.

She subconsciously turned around and looked, and something strange happened.

She found that the exit of the corridor behind her had disappeared, replaced by the wilderness she had seen earlier, and when she turned around, she saw that she was standing in the middle of the corridor again.

In other words, after reaching the exit of the corridor, she returned to the starting point again.

"Interesting!"

Zhou Zhirou did not panic, but showed a smile, this phantom array is a bit special, it seems that no matter which direction you go, you can't get out.

As for the window lattices on both sides of the corridor, Zhou Zhirou had no idea about them at all, and she didn't plan to try to break the window lattices and find an exit from the side.

If I guessed correctly, the window lattices on both sides should actually be something very solid, or simply an illusion caused by the vitality of heaven and earth - like a mirage, if the latter, even if you are exhausted, there is no way to break the window lattice.

You may even see with your own eyes that the window lattice has been broken, but in the next moment, it will be restored to its original state.

"One-step, two-step, three-step......"

Zhou Zhirou walked towards the exit of the corridor again, and could see the direction of the ruins, and as she walked, she silently counted her steps in her heart.

At this time, every time she landed, the distance between her steps and her steps, was completely consistent.

It's like measuring with a ruler, and the score is exactly the same.

"One hundred and one, one hundred and two...... One hundred and eight!"

When she counted one hundred and eight steps, Zhou Zhirou stopped, and at this time, she was about a hundred meters away from the exit of the corridor.

She paused and carefully observed the changes around her—the distance between the two sides of the corridor, the pattern of the window lattices beside her, and so on.

Because, there is a possibility of exit, which is hidden near here.

It's just that until my eyes are sour, I still haven't noticed any different changes around me.

"Hmm? No. Isn't it the corresponding one hundred and eight constellations?" Zhou Zhirou muttered to herself, this phantom array seemed to be different from what she thought.

But it doesn't matter, Miss Zhou's characteristic is that she is not convinced.

is like this in everything, otherwise Xu Feng said at the beginning, if you kick my ass, even if we are even, Miss Zhou will feel very dissatisfied.

"There are so many formations on the Hanging Mountain, they can't be difficult for my aunt and grandmother, is it possible that I will be affected by such a small phantom formation?"

Zhou Zhirou pursed her lips, and the unconvinced and competitive spirit in her heart was stimulated.

In fact, Zhou Zhirou is a formation genius!

Even her grandfather thought so about this.

On the Hanging Mountain, there are dozens of formations, large and small, when Zhou Zhirou was seven years old, except for the extremely complex formation, she was able to come out of the other formations with her eyes closed.

It's her natural ability.

Because, Zhou Zhirou's natal divine seal is the formation - its shape is a pattern composed of several simple lines together. This pattern is a very ordinary method of inscription of the phantom array.

When Zhou Zhirou was just born, her natal divine seal was awakened by her grandfather with a secret method.

This kind of secret method, in the Tian Yuan Continent, very few people know it. According to her grandfather, I'm afraid that only some old antiques who have lived for thousands of years will understand this secret method.

Zhou Zhirou closed her eyes, and behind her, a pattern composed of a few lines slowly emerged.

As soon as this pattern appeared, a faint white light bloomed, and the white light continued to flow on the lines that made up the pattern, adding a bit of mystery to her out of thin air.

"No, the vitality of heaven and earth around me is slowly gathering towards me, proving that my judgment is not wrong!"

Zhou Zhirou opened a bunch of watery beautiful eyes, and her eyes were full of doubts.

Once any formation is successfully arranged, it will continue to absorb the vitality of heaven and earth to ensure that there is enough energy to operate the formation. After absorbing enough Heaven and Earth Vitality, the absorption of Heaven and Earth Vitality will not be so strong.

It's the same thing that a person who has eaten enough to see that the food no longer has the desire to eat.

Therefore, after this, although the formation still needs the impetus of the Heaven and Earth Yuan Qi, the demand has become very small. At this time, you can see the level of the person who inscribes the formation pattern and arranges the formation.

People who are proficient in the formation can make the heaven and earth vitality required by the formation very small, and the formation arranged by people with poor level needs a large amount of heaven and earth vitality to supplement the formation needs all the time - such a formation is easy for people to find a way to crack the formation - as long as the heaven and earth vitality is prevented from being inhaled by the formation, then soon, the formation will be naturally cracked.

Because of the lack of energy provided by the Heaven and Earth Yuan Qi, the formation could not hold on at all.

The more proficient the formation master, the more difficult it is for people to detect the fluctuations of the Heaven and Earth Yuan Qi - even the masters of the Divine Power Realm can't find it!

Zhou Zhirou's natal divine seal has a special natural ability, that is, it can sense the fluctuations of the heaven and earth vitality when any formation is running.

Even the slightest fluctuation can be detected and captured by her natal seal!

"Did I miscalculate?" Zhou Zhirou thought about it carefully, and she was sure that she had not miscalculated.

"Then how did this formation do it?" Zhou Zhirou frowned.

At this moment, suddenly, the light on the lines of the Natal Divine Seal behind her brightened again.

"Huh?" Zhou Zhirou was a little stunned, this faint fluctuation of heaven and earth vitality actually came from behind her.

"I understand, this is an upside-down Yin and Yang Phantom Array!" a flash of light flashed in Zhou Zhirou's mind, "From the very beginning, this Phantom Array has given a hint in the subconscious - if you go in the direction of the wilderness behind you, you will never be able to get out." No matter how you walk, it's so far from the exit at the back!"

"Therefore, no matter who it is, they will choose to move forward, and at this time, they just happened to fall into the plan of arranging the formation law. ”
