"Friends of Taoism, this thing in my hand is a treasure passed down from my ancestors. It is said to be a rare array plate. As long as crystals are inlaid on it, this array plate can take effect and have some power of the original array. This array plate is sold here today, and there is no need to exchange for anything else. The only hope is to accept my grandson as his disciple and ensure that he can enter the Qi Refining Period in the future. As long as a fellow Taoist in the Qi Refining Period, he can complete this transaction, but before the transaction, you must swear with your own inner demon..."

The old man's face was full of wrinkles. When he spoke, his body was still trembling slightly, holding the little boy next to him with one hand.

The boy looked smart, his eyes were smart and clear, and he looked at the monks around him curiously.

"Is this formation plate real?" A middle-aged monk in the Qi Refining Stage walked over curiously.

"Juewuxuyan, this is really a very precious array plate. It only needs to be inlaid with crystals on it to take effect." The old man said confidently.

"Try it first and see if the formation plate is real?" a monk next to him suggested.

The so-called array plate is a prop that carves simplified arrays on special materials. As long as crystals are inlaid on the array plate, the owner of the array plate can control this array with greatly reduced power.

Although the power of the array plate is reduced by half compared to the original array, this type of prop is very practical and loved by many monks who are not good at array.

However, the production of array plates is extremely difficult. Not only is it difficult to find materials, but the makers must have a very thorough understanding of array techniques. Therefore, array plates in the immortal cultivation world are extremely rare, and few people have one array plate. Moreover, even if they have this thing, the power of arrays engraved on the array plate is very limited.

In the entire Three-Star Domain, there are absolutely few people who can make array plates, and most of these people are high-level cultivators with great magical powers. After all, a formation is complicated and profound, and it is difficult to achieve without a long time to study and practice. Even if the low-level cultivators have enough energy, they can only achieve meager achievements in formations.

"This array plate requires four crystals to take effect... But I don't have any crystals in my hand..." The old man said this, his tone was a little hesitant.

"I have crystals here, so try the effect of this formation." Zhao Rui took out four crystals and walked to the old man.

When the monks around saw the crystal in Zhao Rui's hand, their eyes lit up, and some monks' eyes did not even hide their greed.

The old man nodded and said, "Since this fellow Taoist is willing to try it, let's try the power of this formation together."

He took the fist-sized crystal handed over by Zhao Rui with a trembling tremble. The old man's eyes were also filled with a little desire, but he quickly returned to normal and began to inlaid the four crystals on it.

The array plate in the old man's hand was about the size of a chessboard, in the shape of a disc, with obscure textures and symbols carved on it. There are several depressions on the back of the array plate, which can be used to inlaid crystals.

After a while, the old man inlaid four crystal stones on this array plate. Everyone present stared at this array plate, wanting to see what its power was.

When all four crystal stones were embedded on the array plate, a strange look appeared on the old man's face. After a long breath or two, he did not see any reaction on the array plate.

"It turned out to be a fake array plate. Why would I say that an old man in the Qi-induced stage will have an array plate in his hand?"

"Maybe it's because this array plate has gone through too long, and this thing has become invalid."

"I think this old man is completely trying to fool people, so he almost fell for it."

...

The monks around were talking, mostly accusing the old man of being unkind.

A few beads of sweat oozed out of the old man's forehead, and he looked anxiously studying the array plate in his hand, but it was true that there was no reaction on the array plate.

Zhang Heng used his spiritual sense to observe the array disk from the body, and vaguely found that there were several cracks on the crystal embedded in the array disk.

Ordinary crystals have a certain reserve of spiritual energy. If a small amount of spiritual energy is lost, it can still be recovered slowly. If the spiritual energy in the crystals is lost too much, it will be difficult to replenish it. If most of the spiritual energy inside is used, cracks will appear on the surface.

And these crystals were still good when they were in Zhao Rui's hands, and cracks occurred in just a moment.

What does this mean? Zhang Heng's heart moved. Perhaps this array plate is real. The problem is that the crystal is that the lower-grade crystal cannot activate the formation at all. Only using more advanced crystals can take effect.

After a while, the disk suddenly lit up, but it became dim in an instant.

Then, the crystals on the back of the array plate turned into powder and fell to the ground.

The four crystal stones were scrapped like this.

The old man looked dead and said to Zhao Rui tremblingly: "This... I don't know why... It's the first time I've used this array disk."

Other monks were also shocked by this strange phenomenon. Naturally, some monks could guess that the activation of the array plate was ineffective because of insufficient crystal level.

Zhao Rui was also very depressed, but he didn't expect that the four crystal stones would be scrapped in just a while.

"Fellow Taoist, it's my little brother, I'll scrap your crystal. Then I'll trade this array plate for you." The old man turned his eyes and started this idea. He secretly looked at the other person's face, then said: "You have also seen that this array plate must be of high level, and ordinary crystals cannot activate it at all..."

Zhao Rui said unhappily: "But I don't have high-level crystals to use him. It's useless for you to give me this array plate."

The monks around him nodded frequently, thinking that what Zhao Rui said made sense. It is almost impossible for ordinary monks to have crystals of higher grades in their hands. Even if they have one, they will not be wasted on this formation plate.

The higher the level of crystal, the more beneficial it is to the cultivator's cultivation. Moreover, the higher-level crystal, the speed of recovery of spiritual energy is relatively large, and the number of times it is used can also be increased.

Indeed, low-level monks cannot afford such a formation disk, and perhaps high-level monks need such expensive props.

Many monks around him lit up their eyes. If they dedicated this formation plate to high-level monks, wouldn’t they get great benefits?

A array plate that requires higher-level crystals to be activated will definitely not be ordinary goods.

A face-slimming monk immediately squeezed in front of Zhao Rui: "Brother, why don't I give you four crystals and give me this array plate."

When Zhao Rui heard this, he was quite moved.

He turned to Zhang Heng and asked, "Senior Brother Tang, what should I do?"

Zhang Heng pondered for a moment and asked the old man: "Are you going to take your grandson as your disciple as soon as you collect this array plate?"

The old man nodded and said, "Yes... and the inner demon can swear by him to ensure that he can reach the Qi Refining Stage."

Zhang Heng frowned and couldn't help but ask, "Your grandson is not a waste of spiritual roots, right?"

The old man's expression changed and he looked at Zhang Heng with some anger, then said with a dim expression: "Yes, Feng'er is indeed a useless spiritual root..."

As soon as these words were spoken, the monks around couldn't help but shake their heads.

The face-slimming monk who was about to trade with Zhao Rui also gave up and ran away.

Just kidding, letting people with devoid of spiritual roots practice immortality is harder than directly challenging high-level monks.

In theory, it is possible to cultivate immortality by aborting spiritual roots, but in fact it is impossible to embark on the path of cultivation of immortality at all.

In the tens of thousands of years of history of the Three Star Domain, there are very few people who can embark on the path of immortal cultivation with their use of their waste spiritual roots.

It can be said that there is no great opportunity, or that a high-level monk is willing to sacrifice his skills to cleanse his marrow and bones, and the use of spiritual roots is equivalent to having no fate with the immortal path.

It is completely impossible for these cultivators in the Qi Refining Stage to take the child with the useless spirit roots as their disciples and swear to let him enter the Qi Refining Stage with the inner demon.

When every cultivator breaks through the bottleneck in his cultivation, he needs the corresponding state of mind to cooperate. Once there are flaws in his state of mind, he is likely to be taken advantage of by the inner demon and end up in a devilish way.

Therefore, once it involves making a swearing with the inner demon, most immortal cultivators will be cautious and cautious, and will never joke with the inner demon. That thing has no effect on ordinary mortals, but it is very effective for immortal cultivators.

Just as all the monks around him retreated, Zhang Heng stood up and said calmly: "Since that's the case, leave this formation plate for me."

With a "wow", the eyes of the monks around him fell on Zhang Heng's face, looking at him as if he was foolish.
