Back in his cave, Lu Chen sat quietly on the futon, took out the "Primary Array Talisman", and began to study carefully.

The formation has a long history, the ancient monks arranged the spiritual stones according to the direction, and a certain flow of spiritual power will be generated within the coverage of the spiritual stones, and the monks will adjust the direction of the arrangement according to their own wishes, so as to guide the flow of spiritual power, which is the origin of the formation.

After a lot of practice, the predecessors of the Immortal Cultivation Realm gradually explored and recorded the prohibitions, and up to now, the number of prohibitions has reached millions, countless and countless.

To cultivate the formation, it is necessary to take it step by step and persist in accumulating it for a long time, not in a day.

The way of the array lies in enlightenment and understanding.

And the basic formation, or prohibition, lies in memory.

This memory is also complex and is the basis for the next change. Every basic formation must be established in mind, and this step can be regarded as a slight achievement.

The basic formations included in the "Primary Formation" have about a thousand kinds of formations, mainly the formations of the first order to the fourth order.

The first thing Lu Chen had to do was to be able to memorize all these thousand formations, and then practice, practice, practice, and practice until he thought of a certain formation, and he could lay it out in the shortest possible time.

These thousand formations can be divided into four main categories:

The first type is the phantom array, in which the illusion array is also real and illusory, and all kinds of fantasies permeate it.

Some are the monk's most desired wishes, some are the monk's most fearful experiences in the past, and some are some happy memories that make people fall into it and can't extricate themselves!

These are just rudimentary phantom arrays. The more advanced phantom array is to obtain information directly from the monk's sea of knowledge, thus revealing the unforgettable memory of the monk's deep sea of knowledge.

Everything in that illusion is like reality, even if you know that it is an illusion, you will fall into it, and if you are taken advantage of by the illusion to trigger the demons, you can make it irreversible.

Like the demon fox that Lu Chen's outer gate Dabi encountered, he can arrange these phantom arrays!

The second type is the killing array, which is extremely evil and focuses on killing the enemy. Because of the fear of killing all of them and hurting the heavens and peace, the people who set up the formation usually have a chance to live.

The killing array is the most powerful of all the types of formations, once it is caught in it, it is usually the end of the destruction of the original gods, although the killing array is huge, but it is less unpredictable, because of this, the killing array is also the easiest formation to break.

To arrange a killing array, in addition to arranging spirit stones, you also need other killing magic weapons or materials.

The third type is the trapped formation, which aims to trap the enemy, and there are usually many prohibitions hidden in the trapped formation, which are used to weaken the enemy's strength and make it impossible to get out of the trap.

The fourth type is the superposition of formations, which is commonly understood, that is, several formations are combined, first trapping the enemy, then luring them into the illusion, and finally destroying the enemy with a hidden killing array.

"Primary Formation" has an evaluation of the formation, which touched Lu Chen a lot:

"The formation is to use the power of heaven and earth to resist the enemy, once you fall into the formation, it is equivalent to fighting with heaven and earth. The highest-level immortal array is said to be able to destroy the heavens and the earth, and it can also open the heavens and the earth. ”

"In order to avenge my family, I must practice the formation talisman well!" Lu Chen secretly made up his mind.

Practice makes perfect, and it is not difficult to memorize these thousand formations, but the difficult thing is the actual formation.

The formation requires extremely high accuracy and timing, a spirit stone deviates from a little angle and destroys the formation, even if the dozens of spirit stones thrown in front of it are very accurate, the entire formation will be wasted, and it will be in vain.

And timing is also very important, some formations require a certain step to be completed within a certain time, one minute earlier and one minute later, it is not possible.

Lu Chen threw spirit stones over and over again in the open space outside his cave, learning to set up the formation, and then rearranged it if he failed.

Keep throwing, keep picking up, and keep throwing, and in the end, Lu Chen can be thrown for several hours in a row without a single difference.

Keep throwing, keep picking up, keep throwing, and in the end, Lu Chen began to throw a formation from a hundred zhang away.

No matter day or night, wind or rain, keep throwing, keep picking up, and keep throwing.

In the end, Lu Chen can adjust the angle, strength and direction of the spirit stone projection according to different weather, so as to accurately and quickly arrange the formation.

The wrists kept flicking, and the spirit stones kept being thrown, and one formation after another was laid out. Moreover, the speed of the formation is getting faster and faster, and now it is possible to lay out a basic formation in a few breaths.

After a year of hard study, Lu Chen has mastered the basic formation and the technique of arranging the formation.

What Lu Chen didn't notice was that every day when he was practicing the formation, a small gap would appear in the gate of the cave next to him, yes, it was Luo Linger peeking at Lu Chen.

At first, cultivation was too boring to have some fun, but gradually, later, it became Luo Ling'er's daily habit.

Luo Ling'er had seen too many children of the Immortal Cultivation Family with prominent family backgrounds in the Upper Realm, but it was the first time she had encountered a teenager like Lu Chen, who was racing against time to cultivate.

Maybe she didn't even notice it at the moment, Lu Chen's figure had slowly sown seeds in her heart.
