After Li Haiya left, Su Chen practiced the technique of carving the formation he taught in the room.

Four hours later, Su Chen was almost proficient, and the speed of using this technique to depict the Spirit Gathering Array was already on par with the previous one.

Su Chen calculated in his heart, if he was really proficient in this method of depicting the formation, he would be able to carve a spirit gathering array in about three minutes!

This speed boost is simply terrifying!

However, Su Chen didn't continue practicing, his spiritual power was almost consumed, and if he continued to do so, he would fall into a state of prostration, and some of the gains outweighed the losses.

With a long breath, Su Chen walked to the bed and sat down cross-legged and began to cultivate.

……

It wasn't until the next morning that Su Chen opened his eyes and exhaled a breath of turbidity.

Standing up and feeling the situation in his body, Su Chen's face showed a touch of joy, and he could feel that his spiritual power had increased a lot.

It seems that the Tranquility Array in this room is still very useful.

Knock knock.

The knock on the door suddenly remembered.

Su Chen stepped forward and opened the door, and found that it was Jiang Tingxue standing outside.

"Master asked you to go to the hall. Jiang Tingxue's expression was a little serious, and after finishing speaking, he turned around and left directly.

Su Chen was stunned for a moment, not knowing what had happened, but he had a faint bad premonition in his heart, and followed Jiang Tingxue and walked towards the hall.

When he arrived at the hall, Su Chen saw Li Haiya sitting in the main seat, his face solemn, and he didn't know what he was thinking.

"Su Chen is here, sit down. Seeing Su Chen coming, Li Haiya greeted him and motioned for him to sit next to him.

Su Chen frowned, sensing that something was wrong, but he didn't say anything and sat down directly.

"Su Chen, what is the relationship between you and the Wu Qiaoxian you told me yesterday?" After Su Chen sat down, Li Haiya asked directly without any pause.

Su Chen was stunned for a moment, he didn't know why Li Haiya suddenly asked about this again, paused, and replied truthfully: "Teacher, I have nothing to do with him, it's just that my male friend and Wu Qiaoxian participated in the trial of Lingxu Academy enrollment at the same time, but my friend failed, and Wu Qiaoxian successfully entered." ”

"My friend seems to have some story with her, so I asked her to help ask, do you remember the original agreement with the two?"

"Teacher, you suddenly asked me this question, is it because of Wu Qiaoxian's news?"

When Su Chen answered, Li Haiya kept staring at him closely, paying attention to the change in his expression.

Seeing that Su Chen had no sign of speaking, Li Haiya said with a serious face: "That's right, I have already investigated the matter of Wu Qiaoxian, he did stay in the Lingxu Academy decades ago, but then she joined the Hades Temple under the bewitchment of the Hades Temple and betrayed our Lingxu Academy!"

"What!"

Su Chen suddenly showed a shocked look, he never expected this.

At the same time, he also understood why Li Haiya was so serious.

After all, the Hades Temple is an incomparably evil existence in the Spirit Ruins, and even the illusion created by Li Haiya yesterday also set the Hades Temple as the villain!

And Wu Qiaoxian betrayed from Lingxu Academy to the Hades Temple, she is completely a traitor, no different from Yang Boyuan who Su Chen killed!

"Su Chen, no matter what your relationship with that friend is, but from today onwards, you don't have to conduct any more investigations on Wu Qiaoxian. Li Haiya thought for a moment.

He still trusts Su Chen, but others are not necessarily, if he knew that Su Chen was asking about Wu Qiaoxian, maybe he would think something.

Moreover, some people who have a grudge against Su Chen are likely to use this to spread rumors about the relationship between him and Wu Qiaoxian to the dean.

Su Chen also knew the importance of this matter, nodded, and was ready to tell him the truth about this matter after seeing Ye Kunming.

"Yesterday I taught you how to depict the formation, how did you practice?" Li Haiya did not continue to say more on this matter, and changed the subject.

Su Chen replied respectfully: "It's almost familiar, and it is estimated that after practicing for another day or two, you will be truly proficient." ”

Li Haiya nodded with satisfaction: "Very good, you can practice this technique to depict the formation in the past few days, and when you are completely proficient, come to my residence to find me." ”

After saying that, Li Haiya got up and left the hall.

After that, Su Chen also returned to his room and continued to practice the carving formation.

As for Wu Qiaoxian's matter, Su Chen didn't think much about it, after all, if Wu Qiaoxian was in Lingxu Academy or other places, he could still try to find her and complete the thing he promised Ye Kongming.

But now that Wu Qiaoxian has joined the Hades Temple and has become an evil way, he has no choice but to use other ways to make up for Ye Kunming's favor.

For the rest of the time, Su Chen stayed in the room to practice the formation carving, rested when his mental power was exhausted, and continued to practice after resting.

By the third day, he had finally mastered the technique and could skillfully use it to depict various formations.

Of course, it is only within Su Chen's ability.

After mastering the technique, Su Chen found the door of his room according to Li Haiya's previous instructions, raised his hand and knocked on the door.

Knock knock.

There was a knock on the door.

Then, the door opened automatically, and Su Chen looked into the room and saw Li Haiya sitting leisurely at the table drinking tea.

"Come in. After drinking a cup of tea, Li Haiya put the teacup on the table and said lightly.

Su Chen didn't say anything and walked into the room.

"Sit. Li Haiya stretched out his hand to the seat next to him.

Su Chen was a little puzzled, but he didn't ask too much, and sat down according to Li Haiya's instructions.

Li Haiya poured Su Chen a cup of tea, and said lightly: "Since you have come to me, I think you have mastered the technique of carving the formation, today I want to ask you how much you know about the level of the formation." ”

"Is there still a level in the formation?" Su Chen was stunned for a moment, it was the first time he had heard of such a thing.

Li Haiya nodded lightly and said: "Of course, in Lingxu Academy, the pills are divided into one to nine grades, and the martial arts are divided into four levels: human level, Xuan level, earth level, and heaven level, and the formation also has strength and weakness, since there are strength and weakness, there are naturally levels. ”

When Su Chen heard this, he looked interested and said, "I don't know this yet, and I ask the teacher to tell me." ”

Li Haiya glanced at Su Chen and said lightly: "In fact, the level of the formation is far less clear than the other divisions, it is roughly divided into three levels, namely the magic array, the heavenly array, and the Dao array, but although there are levels, the attributes of some formations are different, so sometimes the same level of formation, one of them will be killed by the other side." ”

As soon as these words came out, Su Chen couldn't help frowning, and asked puzzledly, "In that case, is there any point in the division of ranks?"
