The next day, when Li Changding was teaching mathematics, Gu Yan came, accompanied by a man of the same age.

Sitting in the back row, watching the smiling Li Changding stand on the podium and give a lecture. As soon as he started speaking, Gu Yan noticed the difference.

The first is attention, he found that it was difficult to take his eyes off Li Changding's body, as if he had a special force field on his body, which firmly attracted the attention of everyone present.

Secondly, Gu Yan found that his mind was very clear, at this time, every word Li Changding said was engraved in his mind as if he had been carved with a knife, which was extremely clear, and the pictures and words on the blackboard were also unforgettable.

Gu Yan looked around for a while, everyone present was the same, looking at the podium where Li Changding was very seriously, listening attentively to his lecture, and at the same time following Li Changding's guidance, looking at the pictures and words on the blackboard, which were the essence of various mathematical formulas and Li Changding's summary.

Ten minutes passed, twenty minutes passed, and half an hour passed, Gu Yan, like the students present, did not have a trace of distraction during the period, and he was still concentrated.

Puzzled in his heart, Gu Yan felt it quietly, and there was an invisible force field permeating the classroom, and all kinds of irrationalities about himself seemed to come from this invisible mysterious force field.

With a thought in his mind, Gu Yan effortlessly got rid of the influence of the mysterious force field, and sensed the source of this force field with his heart.

Glancing at the four corners of the ceiling of the classroom, there was a jade talisman hanging there, which he had discovered when he first came yesterday, but the four jade talismans had no brilliance at that time, and he didn't sense the slightest aura on them, thinking that it was just an ordinary jade pendant for decoration, so he didn't care.

At that time, he was still thinking in his heart, what a delicate jade talisman, the rune turns between the charm, it must come from the master's hand, and then look at the jade quality, it is obviously a high-grade jade, but unfortunately it is an ornament. It's a tyrannical thing!

I don't want to, look at it now, the four jade talismans are all shining with a faint light, exuding a special force field, four jade pendants, and four forces are superimposed on each other, forming a huge force field that envelops the entire classroom.

This force has other effects besides calming the mind, Gu Yan understands that the reason why the people in the classroom have been able to listen to the class with full attention until now is because of this force field.

Obviously, those four jade talismans were able to restrain their own spiritual power, and not overflow the slightest brilliance aura when they were not in use, so as to prolong the number of uses.

I wonder whose work this is? This alone shows that the level of the maker is far above his own. Gu Yan thought in his heart.

In addition, there is also a force, Gu Yan sensed, this power came from Li Changding's feet - the podium.

It is this force that makes every sentence of Li Changding, every word on the blackboard, and every picture extremely attractive, making people feel impressive, and it is difficult to forget.

Gu Yan smiled bitterly, he didn't expect Li Changding to use this method to teach. No wonder he was so confident that all of his students would be able to pass the graded exams.

According to his own feelings now, those students don't even need to review after class, and at least for three years, they will not forget the key points of Li Changding's teaching.

"I said, why are you so confident? It turned out to be the power of a charm. After class, Gu Yan looked at Li Changding inexplicably.

"What? Isn't that possible? Li Changding asked with a smile.

"Of course not. But where did you get the jade talisman? Compared to Li Changding's teaching with talismans, Gu Yan was more curious about the master of refining jade talismans, although it was just a Gathering Talisman and a Confusing Talisman, they were all the most ordinary kinds, but the simpler it was, the more powerful it was, for an insider like him, a few ordinary jade talismans had already shown the author's extraordinary level, definitely above him, and few of his peers could be compared!

"I did it myself, of course." Li Changding said with a smile.

"You? Do you still have spells? Gu Yan was very surprised, "I always thought that you would only be able to refine the pill!" When the hell did you learn the spell! ”

"I've just focused on alchemy in the past year, and I actually gave you the illusion that I can only do alchemy! Hehe! To tell you the truth, in fact, before I studied alchemy, I already had good attainments in talismans. Otherwise, what am I going to do with those spirit runes and formation drawings you gave me? Does it look good? Li Changding looked at Gu Yan playfully.

Gu Yan looked at Li Changding resentfully, and was about to complain a few words, when Li Changding suddenly said, "This friend by your side, aren't you going to introduce it?" ”

"Oh, this is a fellow disciple of mine, named Jiang Ming, I happened to meet him on the way here, so let's take a look." Gu Yan first introduced Jiang Ming to Li Changding, and then turned to Jiang Ming and said, "This is a friend of mine, named Li Changding, don't look at his young age, he is a fifth-order!" ”

"Li Changding? Fifth order? Jiang Ming muttered a few words, and then said in surprise: "You are Li Changding!" That youngest fifth-order powerhouse ever! ”

"Yes." Li Changding nodded, and then whispered a few words: "Low-key, low-key." ”

"Oh, oh. You! Hello! Hello! Seeing the idol in his mind, Jiang was obviously very excited, he was only a second-order junior and had the ambition to cultivate, so he would inquire about all kinds of things in the cultivation world, and the most explosive news in the imperial cultivation world in recent years was that a member of the Li family named Li Changding, a minor child who was only fifteen years old had achieved the fifth order, becoming the youngest fifth-order person who had never been seen before, and it was estimated that he would also be the youngest fifth-order person who had never come before.

For Jiang Ming, this is simply an incredible miracle. Although he himself worked hard, studied hard, and did not dare to slack off for a moment, but his qualifications were too poor, and he was not a wealthy and noble family, and his resources were insufficient, and his cultivation progress was the same as that of a turtle crawling, but nearly twenty years of cultivation had only allowed him to reach the second-order primary level, and he had just condensed the Yin God. And the young man in front of him, who is at least ten years younger than himself, has reached a state where he can't even think about it.

Of course, the main reason for Jiang Ming's nervousness was that he had finally seen the fifth order!

Don't think that Li Changding has a grandfather who is a fifth-order, and Fang Xin has a mother-in-law who is a fifth-order, so you think that the fifth-order is easy to see. The number of fifth-order people is scarce, and most of them live in isolation, and they will not appear in front of the world, even if some activities of the fifth order will appear, because of their noble status, it is not something that people like Jiang Ming who are at the bottom of the cultivator can access.

Jiang Ming met Li Changding, which was equivalent to a director of the sub-district office of the Celestial Empire meeting the governor of his own province, unless he was indifferent to the future, or his mental quality was particularly good, how could he not be nervous?

Li Changding politely said a few words to Jiang Ming, and then talked about business with Gu Yan: "How is it?" Are you interested in doing things with me? ”
