Zhang Yanchong silently thanked Wen Jiushan for making annotations for himself in the bottom of his heart, and then Zhang Yanchong drew a strange figure with his fingers on the ground, the image was like a labyrinth, the lines twisted but always unable to see its end and beginning.

Finally, Zhang Yanchong took out a crystal stone with yellow aura from the black ring and placed it in the center of the figure.

That stone was the kind that Zhang Yanchong had obtained in Ah San's storage bag, this kind of stone was called a spirit stone, which could not only replenish the mana of cultivators to a certain extent in battle, but also be used as currency between cultivators.

And the role of the spirit stone is definitely not limited to these two points, for example, now, Zhang Yanchong's spirit stone is used as the energy source of this miniature formation that he will urge.

As soon as the spirit stone was put in, it immediately emitted a more intense yellow light, and then the strange pattern on the ground seemed to turn into a living one, and after a writhing, suddenly a thick mist quickly filled the top of the pattern. Even if Zhang Yanchong was close in front of him, he couldn't see the ground behind the dense fog.

Looking at this mini fog array, the corners of Zhang Yanchong's mouth couldn't help but show a satisfied smile.

A few days later, around the tree hole where Zhang Yanchong lived, a thick fog suddenly filled the air, and the tree hole was directly hidden between the dense fog, and at this time, Zhang Yanchong, who was still in the tree hole, was using his divine sense to sweep the area shrouded in the thick fog, Zhang Yanchong suddenly had a feeling that the land occupied was king, within the scope of his own formation, it seemed that any invasion of foreign enemies could not escape Zhang Yanchong's observation.

Not long ago, after Zhang Yanchong successfully experimented with the miniature fog array, he spent a lot of effort carving the same enlarged version of the fog array around his tree hole to verify his mastery of the fog array.

The result made Zhang Yanchong very satisfied, the arrangement of the fog array was almost difficult, this was not because Zhang Yanchong's mana was profound, the arrangement of the formation had little to do with the mana, the key was to see the arranger's comprehension of the formation.

Of course, Zhang Yanchong's comprehension is not to say how high it is, he successfully arranged the fog array, on the one hand, the fog array is the simplest in this book, and it is used to let beginners understand the formation practice, and on the other hand, it is thanks to Wen Jiushan's detailed annotations in the book.

Zhang Yanchong felt the mystery of the formation, so he calmed down again, and put the few spirit stones used for the energy in front of him into the storage bag, and the dense fog also dissipated at the same time.

Zhang Yanchong didn't want to waste his already small number of spirit stones in this useless formation, and if he really put out the fog array, it would really attract the attention of other cultivators nearby.

Therefore, this kind of thankless work is still not good.

Moreover, the spirit stones saved would also be used for the practice of other formations, so Zhang Yanchong began to study a real and practical phantom formation.

Of course, the real formation is not something that can be completed with a few simple lines, and if you want the formation to have more powerful power, some better quality formation equipment is indispensable.

Fortunately, in the black ring, there is no shortage of equipment for arranging formations, which shows that Wen Jiushan was definitely a cultivator who was good at formations during his lifetime.

The black ring emitted a ray of light, and in the light, artifacts of different shapes flew out one after another.

Among these artifacts, some are flags, some are pillars that seem to be metal, and there are some strange items that Zhang Yanchong can't describe, these artifacts at first glance Zhang Yanchong thought they were some low-level magic weapons, but after carefully checking them with his divine sense, Zhang Yanchong knew that these were by no means magic weapons, and these artifacts had no effect at all if they were used alone, but were made of special materials by monks and used to arrange formations.

The utensils were ready, and Zhang Yanchong carefully arranged them in the tree hole.

Half a day later, outside the tree hole where Zhang Yanchong was, if someone was nearby, they would definitely think that there was something wrong with their eyes.

For at this moment the great tree, with its hollow, suddenly vanished, and disappeared without warning, and disappeared out of thin air, and in the original ground of the tree, it was replaced by a bush like the rest of the forest.

But this scene lasted only a moment, and then it changed again, and the tree reappeared, and everything just now was like a mirage, and there was no trace left.

Zhang Yanchong held the yellow spirit stone whose light had dimmed in his hand and looked at the array equipment on the ground, with a strange smile on his face.

Just now he successfully laid out a fairly advanced formation in the book, the illusion array, the role of the illusion array can be seen from the name, this formation is to make people's vision deviate, can hide the traces of some things.

However, the effect of this formation is actually very limited, it only confuses people's vision, and once people really get close to the bushes that appeared before, they will find that they can't even pass through the bushes, but will bump into something.

After all, the hidden tree still exists, and cultivators with a little common sense will immediately realize that there must be a mystery here.

And what made Zhang Yanchong even more painful was that the consumption of the formation for the spirit stone was really not ordinary, Zhang Yanchong had not activated the illusion array for a while, and the spiritual power in this spirit stone had disappeared quickly, if Zhang Yanchong hadn't taken back the spirit stone in time, this spirit stone would have become an ordinary stone.

Zhang Yanchong hadn't felt much about this when he was in the first formation, but when he operated the more advanced illusion array, he realized that his spirit stone was not enough to support him to learn all the formations in this book.

On the one hand, it was the joy of successfully arranging the illusion array, and on the other hand, it was the entanglement of the consumption of spirit stones, and Zhang Yanchong's heart of fighting made his smile a little strange.

Where the spirit stone will definitely be useful in the future, should he spend the spirit stone on practicing the formation?

These formations are not necessarily useful when they come, after all, the formations need to be arranged in advance, and then they can only have an effect when they lure the enemy forward, and in the case of spirit stones, Zhang Yanchong can replenish mana during battle, which sounds much more practical than arranging formations.

And even if Zhang Yanchong spent all his spirit stones to learn one or two sets of powerful magic circles, there would be no spirit stones to use in the real battle** Zhang Yanchong.

After some consideration, Zhang Yanchong finally decided to suspend the cultivation of the formation method, and wait until he went out in the future, and if he had the opportunity to earn enough spiritual knowledge, he would consider this aspect of the matter.

The study of the formation also had to die.

However, he couldn't practice arranging formations, but it didn't delay Zhang Yanchong from continuing to study the mysteries of these formations, but without practice, Zhang Yanchong couldn't really learn to arrange these formations, but if Zhang Yanchong really encountered a phantom formation or something like that in the future, he would no longer be helpless or break the formation with brute force as before.
