"In that case, I will fulfill you", Elder Feng pointed to the sky with one hand, attracting a heavenly thunder, which tore through the sky and rushed down.

Rumble!

Du Ziteng was wiped out.

As soon as he died like this, a group of elders lying behind him struggled to get up regardless of his physical injuries and kept begging for mercy: "Elder Feng, spare your life, we are also forced by Du Ziteng's coercion." ”

"Elder Feng, please read that we have been teaching the ground class diligently for so many years, and have trained a lot of talents for the Wuji Sect, bypass us."

"Talent?" , Elder Feng smiled contemptuously, "Those you have cultivated are all beasts who do all kinds of evil!" As soon as these words came out, the faces of the few people who had been begging for mercy just now were like ashes.

"Forget it", Elder Feng waved his hand, "Although there is no merit, there is also hard work, so your life will be left with you for the time being!" ”

"Thank you, Elder Feng!" The five ground class elders breathed a sigh of relief in their hearts, and supported each other to roll back to the ground class. Ling Tian stepped forward at this time and half-knelt down towards Elder Feng, "Congratulations to Elder Feng, you have comprehended the second nature change. ”

Ling Tian turned his head to look at Xu Yichen and Lin Zhihai: "If you haven't come over to salute yet, this Elder Feng is the dean of the Psychic Academy." ”

Xu Yichen guessed that this person must have come from a lot of ways, and stepped forward to salute Elder Feng: "Thank you Elder Feng for upholding justice and returning my innocence." ”

Elder Feng looked Xu Yichen up and down, and after half a salary, he stroked his beard lightly and asked Xu Yichen thoughtfully, "How much do you know about yourself?" ”

Xu Yichen immediately understood what Elder Feng meant. His spiritual power is different from ordinary people, and there is also the seal in the spiritual source, the demon in the spiritual source is like a demon in another world, and he also wants to understand everything.

"I don't know much!" Xu Yichen replied truthfully, "Elder Wangfeng made it clear. ”

Elder Feng stroked his long beard and smiled slightly, he looked at Ling Tian: "You, there is a long way to go!" After saying that, there was a gust of wind, and Elder Feng disappeared without a trace.

Ling Tian looked at Xu Yichen and Lin Zhihai, and said solemnly: "Tomorrow, the Huang class will conduct the first lesson of the Psychic Academy!" After saying that, another gust of wind, Ling Tian also disappeared without a trace.

"This wind system spiritual power really comes and goes without a trace, and it is extremely chic~", Lin Zhihai sighed heartily when he saw that Elder Feng and Ling Tian came and went freely, floating between heaven and earth.

"Then hurry up and comprehend the nature change of the wind system's spiritual power, and then you can be like them." The two looked at each other and smiled. Then they went back to their rooms.

——

The next day, the class in the yellow class was overcrowded, and all the people who had run away had returned. Ling Tian walked into the classroom, looked at the full house of students, and shouted, "Who let you in?" ”

"Elder Ling...... We~" Those people stood up in a daze, and said, "We~ want to learn spiritual arts from you......"

"Hmph", Ling Tian ignored the words of several people, and instead smiled contemptuously: "Do you know what the consequences of trespassing into the Psychic Academy are?" I'll give you five minutes, or don't blame me for being merciless! ”

Those people, including Zhou Ping, were stunned in place, not knowing what to do, he knew that what they had done was not worthy of sitting here, but he didn't expect Ling Tian to be so ruthless, he didn't even give him a chance to intercede.

"There are three minutes left", Ling Tian smiled when he saw that everyone was not moving, and at the same time, the spiritual power lingered in the palm of his hand, and he could kill at any time.

Seeing that Ling Tian was serious, these people also panicked and hurriedly ran out. After a while, there were three people left in the classroom, except for Xu Yichen and Lin Zhihai.

Lin Zhihai angrily reprimanded Zhou Ping: "Brother Yichen provoked those people because of your grievances, you are good, you ran away without saying a word, are you embarrassed to stand here?" ”

Ling Tian also looked at Zhou Ping: "You're not afraid that I will kill you?" ”

Zhou Ping clenched his fists, lowered his head, and seemed to be struggling with something in his heart, he gritted his teeth, raised his hand and looked directly at Ling Tian: "I am qualified to stand here!" ”

"I have low strength and can't compete with them, but for so many years, I have never left the Yellow Class, and I will do my best to at least keep the Yellow Class clean."

"In that case, you stay!" Ling Tian didn't know what Zhou Ping was doing, and he didn't feel sorry for him, "Let's start class!" ”

"Today is the first lesson of the Psychic Academy, the course title is: Spiritual Power and Spiritual Arts", Ling Tian walked to the middle of the podium and said to the three people in the audience, and at the same time he spread out his hands to refine the spiritual power in his palm: "This colorless, tasteless and formless substance is spiritual power, although it cannot be seen, but anyone who has spiritual cultivation can sense his existence." ”

"Spiritual power, as the name suggests, is the power of the soul."

"The power of the soul is stored in the spiritual source, and after cultivation, it is allowed to walk in the spiritual veins for the use of psychicists."

"Spirituality is to strengthen the spiritual vein, so that the spiritual vein capacity is larger, and the spiritual power flows faster."

For the whole morning, Ling Tian didn't say a word about yesterday's events, and he was all talking to the three people in the audience about the basic theory of spiritual power, including its structure, the principles of spiritual arts, and so on.

"Now I'll set an example for the two of you!" Ling Tian once again gathered spiritual power in the palm of his hand, and that spiritual power spun at a high speed, forming a spiral spirit technique: "This is the form change of spiritual power, and a spiritual technique is based on this. ”

After speaking, the spiritual power in Ling Tian's hand changed again. Xu Yichen felt that spiritual power dissipate, and a breeze blew in the classroom.

"This is the change in the nature of spiritual power."

Ling Tian continued to move, and in the breeze, several thin blades were formed. The thin blade cut into the walls around the classroom, bringing out the scratches. Ling Tian controlled it very well, the scratches were not deep, but they were just enough to be clearly visible.

"This is a secondary nature change."

"Level 2 nature change?" Xu Yichen and Lin Zhihai both recited silently. Ling Tian continued: "The second-level nature change is actually the use of form change on the basis of the nature change. ”

Xu Yichen remembered yesterday's battle, Ling Tian manipulated the wind to form a wind dragon, a wind blade, and a wind sword, and that form and feeling were completely different from his Infinite Blade. Now he also understood that the Infinite Blade was not a first-stage spiritual technique, but it was indeed only a third-stage spiritual technique, which was far from Ling Tian's use of the second-level nature change condensed wind sword.

Moreover, he later learned from Ling Tian's mouth that the Wind Dragon and the Wind Blade were not spiritual arts, but were only controlled by the second-level nature changes of spiritual power. It can be seen from this that the change in the nature of spiritual power will be a leap in strength for a spiritual person.

"But this is not what you need to master now, the second-level nature change is the hurdle you face when you break through from the peak of the spirit master to the spirit master, and your current task is to comprehend the nature change."

After seven days of study, Xu Yichen also understood what spiritual power and spiritual arts were all about, and he also learned and mastered a large number of basic spiritual techniques, such as the Spiral Spirit Technique, the Spirit Gathering Shield, and the Soul Exploration Technique.

Each person's spiritual power contains five components: wind, fire, thunder, water, and earth. However, the proportion of spiritual power in each person is different. In Ling Tian's words, it was, "There will be no two people in the world who have the same proportion of spiritual power." ”

The highest proportion of each person's spiritual power is the main spirit, and spiritual power of different natures cannot be used together.

Ling Tian likes to use himself as an example in his lectures, and his highest is the wind system spiritual power, accounting for about four out of seven. If he doesn't control the refining of spiritual power and then uses it, only forty or seven percent of the spiritual power will be used, and the rest of the spiritual power will be wasted.

It can be seen from this that it is not only his spiritual cultivation that determines a person's combat effectiveness, but also the purity of spiritual power.

Psychic masters can convert other nature spiritual power into their main spiritual power through nature changes to improve the purity of spiritual power, this is a way of advanced cultivation, and Ling Tian can only increase four out of seven wind spiritual power to five out of two at present.

But Xu Yichen had new doubts.

Xu Yichen could feel that the purity of his spiritual power was very high, and according to Ling Tian, the purity of the main spiritual power could reach more than four layers, and he could easily comprehend the changes in nature. However, Xu Yichen not only did not comprehend the change in nature, but in a few days of cultivation, he did not even feel the slightest fluctuation in his spiritual power.

Moreover, everyone's spiritual power is colorless, tasteless, and invisible, and the spiritual power refined by Xu Yichen turned out to be light blue, and Xu Yichen's Infinite Blade was covered with blue light.

A few days later, Xu Yichen, Lin Zhihai and Zhou Ping followed Ling Tian to the highest place in the Psychic Academy, Tianban!

The heavenly class is worthy of being the best class in the psychic academy, its platform is twice as large as the ground class, and more than ten times larger than the yellow class, each apprentice's accommodation has a separate courtyard, and it can also be equipped with a servant, and even more, some apprentices bring a beautiful maid from home, and everyone knows it.

In addition to the classrooms, there is also a cultivation room to assist in cultivation, and there is also the purpose of Xu Yichen and his party: the spiritual power analysis array.

The spiritual power analysis circle is the analysis of the components of each person's spiritual power, which is unique to the Wuji Gate, and is built on the practice square of the heavenly class of the Psychic Academy.

Each time the formation is opened, it needs the spiritual power of a thousand spirit pills, and it is open once every six months, and the opening time is one day, when the people of the two classes of the Psychic Academy can test it for free, while the two classes of Xuanhuang need to hand in one hundred spirit pills. Of course, the three hundred elixirs of Xu Yichen and the others were from Ling Tian.

There are also wealthy families who will send their children to be tested, and some psychic sects around them regularly send their disciples to test, which not only fills the gap in opening the magic circle, but also makes a small profit for the use of the psychic academy.

"Thank you Elder Ling for your generosity~" Lin Zhihai couldn't help but feel grateful when he learned that this magic circle was so precious.

That Zhou Ping was even more excited to speak, in the past, he didn't dare to talk about Tianban, even if it was Xuanban, he didn't dare to take a step. Now he can even step into the spiritual power analysis circle.

Xu Yichen was also full of gratitude to Ling Tian in his heart, and he also hoped that this spiritual power analysis array could solve the doubts in his heart.

Walking to the cultivation square, around the spiritual power analysis circle, there were eight long dragons, divided into eight directions. Lin Zhihai and Zhou Ping were also lined up behind one of the long dragons.

At this time, Xu Yichen saw a familiar back.
