When Shi Mu walked out of the circular stone platform, the gray-clothed old man's face had returned to calm.

"Dare to ask the seniors, has the elemental sensing ability below reached more than three degrees?" Shi Mu looked at the strange color that flashed on the face of the gray-clothed old man in his eyes, and asked tentatively.

"Ahem, it should ...... Sort of!" The gray-clothed old man stared at Shi Mu with a pair of triangular strange eyes, and his face became strange again.

"Senior, is there anything wrong with the disciple?" Shi Mu was first overjoyed when he heard the answer of the old man in gray, and then when he saw the old man's expression, he faintly felt a little bad in his heart.

"Warlocks are different from martial artists, the strength of a person's elemental sensitivity almost represents the size of their potential in the way of magic. Several of our major sects have already reached a consensus that it is basically impossible for a spirit root with elemental sensitivity below the third degree to advance to a star-level warlock, so even if a lot of resources are consumed, it will be in vain in the end. Therefore, the elemental induction power above the third degree is the limit for the major sects to truly determine whether there is a cultivation value, and if they have a certain elemental induction power above the fifth degree, theoretically there is even a chance to advance to the moon-level warlock. The old man in gray retracted his gaze, and after a slight hesitation, he suddenly explained.

Hearing this, Shi Mu couldn't help but glance sideways at the black crystal pillar, and his mood began to get a little excited.

After seeing Shi Mu's actions, the gray-clothed old man shook his head, as if he was a little sorry, and continued in amazement:

"Except for the black and white crystals, if you excite any of the other crystal pillars to more than five blocks, the door will naturally value you very much. However, the black crystal pillar you inspired, the elemental power represented is a very ethereal space power, and its rarity is almost the second only to the power of time among all elemental powers. Looking at the entire Black Demon Sect, no one has ever stimulated this kind of elemental induction, and there is no official corresponding cultivation method at all. But if you choose these two warlock methods, you will naturally get twice the result with half the effort in cultivation, and the possibility of advancing to a high-level warlock is very small. ”

As soon as the gray-clothed old man said this, Shi Mu was immediately disappointed, but after thinking about it, his heart became calm again.

Before he came in, he had no hope for his talent as a warlock, but now even if he just became an apprentice, it was still a great thing for him.

If he remembered correctly, among the tasks released in the Guangyuan Palace, there were many eye-popping tasks that the warlock apprentice could take.

Thinking of this, Shi Mu couldn't wait in his heart.

"Excuse me, senior, and am I qualified to become a full-fledged warlock apprentice now?" he glanced at the blue and red crystal pillars with some concern, neither of which had reached three squares.

"There is no problem with this!" replied the old man in gray without hesitation.

"Then I can choose to become a formation mage?" As soon as he heard the gray-clothed old man's answer, Shi Mu's eyes flashed with excitement, and he eagerly asked the question he was most concerned about.

"With your qualifications, is there any other choice besides the Array Mage and the Soul Master?" the gray-clothed old man rolled his eyes, and looked a little speechless.

Although the gray-clothed old man's words were mean, to Shi Mu it was like a heavenly sound, and he was extremely excited in his heart, if he could really become a formation mage, he would naturally not have to worry about resources in his cultivation in the future.

"The registered warlock apprentice place is in the real Spirit Law Hall, you come with me!" For a person like Shi Mu who was excited when he first heard that he could become a warlock, the old man in gray had seen a lot.

He ignored Shi Mu, walked directly to the back of the hall, and then groped twice on a seemingly ordinary wall, and with a soft sound, a dark door that came up one person appeared in vain.

Seeing this, Shi Mu hurriedly followed, and secretly marveled at the ingenuity of the design of this mechanism in his heart.

The passage behind the secret door was not long, and the two soon came to a secret room.

The space of the secret room is not large, and the layout is very simple, only a huge circular pattern is inscribed on the ground in the middle, and countless silver patterns and unknown mystical characters are densely packed on the pattern array with some mysterious law.

"Why are you stunned, don't come in yet!" The old man in gray was already standing in the center of the pattern, and when he saw that Shi Mu was still looking around, he couldn't help but stare at him and shouted impatiently.

Shi Mu didn't dare to say much, and hurriedly walked into the array, only then did the old man in gray take out a yellow talisman, and with a flick of his wrist, a flame rose at the top of the talisman, which burned quickly, and soon broke out of the control of the old man in gray, turning into a ball of yellow light wrapped in strange energy and submerging into the array.

There was a "buzz", and the air shook.

The silver patterns and words in the array on the ground seemed to come to life, flowing and spinning, and a trace of white glow emanated, and after a while, the glow rolled upwards, and Shi Mu and the gray-clothed old man disappeared in place.

After a familiar whirlwind, Shi Mu found himself in an underground hall.

The whole hall is made of some unknown cyan stone, covering an area of acres, but it is empty and looks very empty and magnificent, and the top is inlaid with dozens of fist-sized night pearls, illuminating the entire space as bright as day.

In the middle of the hall, there is a huge cyan jade wall, a huge bronze beast head incense burner is placed in front of the jade wall, a purple incense candle the thickness of a baby's arm is inserted straight into the incense burner like a wooden stick, and the head of the incense candle still has gray-black residues after use.

Shi Mu's gaze swept down, and finally landed on the huge cyan jade.

The cyan jade wall is printed with hundreds of different markers from top to bottom, the top two pale red star-shaped markers, the second row are eight cloud-like green markers, and further down, there are more than 100 white light point markers.

All markings are misty and look mysterious.

Looking at these mysterious and abnormal marks, Shi Mu somehow suddenly remembered what Huo Lan said in Chuanxianglou that day, there were only ten warlocks in the Black Demon Sect and more than 100 warlock apprentices, and he had a faint guess in his heart.

"Don't speak, don't look around. The gray-clothed old man suddenly turned grim and shouted.

Shi Mu's heart froze, and he hurriedly stood solemnly with his eyes, nose, nose, and heart, and the atmosphere in the hall instantly became solemn, and the old man in gray nodded with satisfaction, stepped forward, and waved his hand on the giant candle in the incense burner.

With a "swish", the top of the incense candle flashed brightly, and a stream of green smoke that could be discerned by the naked eye rose up.

The old man in gray immediately stood up respectfully.

A moment later, a star-shaped mark on the far left of the top of the cyan jade wall flashed, and a pillar of pale red light erupted from it, dripping and condensing above the incense burner, and then suddenly transformed into a vague phantory shadow.

Shi Mu stared at it, and the phantom was a middle-aged Confucian with long black hair.

"Thank you!" the old man in gray immediately saluted the phantom.
