Li Feng mainly studied the books on formation prohibition and refining, and after coming out of the secret realm of the Coiling Dragon Palm King's retreat this time, he felt that his knowledge was too narrow, and he had too little research on the formation, and if he was ambushed by the formation prohibition in the future, he would definitely suffer a big loss.

As for studying the refining weapon, it was because Li Feng's Xuanfeng Shield was destroyed, which also weakened his strength to a certain extent, and the profession of refiner in Longlan Country was also quite rare, and it would definitely cost a lot to ask them to help repair the Xuanfeng Shield, rather than this, it was better to become a refiner yourself and try to repair the Xuanfeng Shield.

In two months, with Li Feng's unforgettable natural ability, he had finished reading all the books on formations and refining weapons in the Dragon Tooth Academy, and there were more than a thousand of them, large and small, and after Li Feng digested them for a few days, he had fully comprehended all the contents.

Li Feng has already studied the basic knowledge of the formation thoroughly, and the rationality of hundreds of formations is almost understood, at least no matter where he goes, he can judge whether there is a formation ambush from a distance, and even if there is, he knows where the source of the formation is and how to break it.

Not only that, even if Li Feng was asked to personally put out some lethal formations, as long as he was given enough materials, he would be able to put out the big formation.

In terms of refining, Li Feng has mastered the refining materials and various strange flames between heaven and earth, and nearly 100 kinds of refining methods, even if he lets him operate the refining tools himself, he can also refine high-grade weapons, but there is still a distance from refining magic weapons.

Li Feng is not in a hurry, after all, whether it is a formation mage or a refiner, he enjoys extremely high treatment in Longlan Country, but it is difficult to become a climate without at least ten years of cultivation, and Li Feng has already become a quasi-array mage and a quasi-refiner in only two months, which is already an incredible thing in the eyes of ordinary people.

Li Feng went out of Baiyue Building and returned to the dormitory, Yishan and the other three learned that he was back, so they didn't go to class and went to chat with him, Qu Xiaoran still kept complaining that Li Feng hadn't come back for nearly half a year, chattering and complaining.

After Li Feng became famous, although the reputation of Class 10 was not as last in the whole college as before, due to Li Feng's absence, they were still bullied by students in other classes.

However, in Li Feng's opinion, since he pointed out the three of them last time where they should improve their exercises, the three of them have also made great progress, especially Yishan, whose current strength has been able to rank in the top forty of the academy, and the only thing that is inferior to the other classes in Class 10 is that the overall strength is poor.

But this can't be blamed on Fei Wuji's lack of teaching, after all, the talent and qualifications of most students in class ten are not as good as those in other classes, which is a hard injury.

Fei Wuji's temperament is very lazy, whenever there are highly talented students in the academy, the teachers of other classes will go to fight, and sometimes they even have to fight, but Fei Wuji is never willing to fight with others, and he accepts students naturally, and over time, the qualifications of the students in Class 10 are not as good as those in other classes, and they will fall behind.

Li Feng decided to improve Class 10 into the strong class of the Dragon Tooth Academy, he not only wanted to become the first in the academy himself, but also the class he was in also wanted to become the first.

In the next ten days, Li Feng did not go to the academy to take classes, but cultivated in the dormitory, in his opinion, there was no knowledge he wanted to learn in the academy, so he went to class to waste time, but it was not as fast as his own cultivation.

In the evening, Li Feng instructed the three of Yishan to tell the students of Class 10 that if anyone was interested in making up classes in the dormitory after class, Li Feng could give them some pointers.

After Yishan spread the news, the students of Class 10 came to place Li Feng one after another, and it was overcrowded every day.

Li Feng is not stingy, using the 'Light of Martial Wisdom' to guide others to cultivate, although the qualifications of the students of Class 10 are weak, but as long as their exercises are improved and their actual combat skills are increased, they may not be worse than those martial artists of the same level with higher qualifications in battle.

In the past ten days, these students have also made significant progress, and in this way, they will definitely be able to catch up with the students in other classes in less than half a year.

On this day, Yishan and the others went to class, and Li Feng was cultivating in the courtyard, when suddenly a powerful aura suddenly oppressed the entire courtyard.

Li Feng didn't panic, because this aura was very familiar, and suddenly, a long rainbow of light suddenly condensed in mid-air, and the speed was incredible, and it was glimpsing towards him.

Li Feng opened his eyes suddenly, and there was already thunder and lightning beating on his right arm, bursting out with a terrifying aura, and a punch blasted out, and a luster like an electric snake roared out.

Cracking sound......

There was a fierce collision sound in the air, and the luster flickered suddenly and quickly.

An aftermath came to his face, and even though Li Feng used all his strength to perform the Zhenlong Pile Skill, his feet seemed to be embedded in the ground, but he was still vigorously taken back two steps.

"That's right, I haven't seen you for more than three months, and your strength has grown a lot!"

A beautiful shadow suddenly appeared in front of Li Feng, dressed in a slim plain clothes, elegant and graceful, a pair of bright eyes, like a lake, bright and profound, it was Yu Sikite.

"Congratulations to the county lord!"

Li Feng bowed slightly.

"Oh, I wonder what I have to be pleased with?"

Yu Siyuan raised her eyebrows and asked.

"The county lord can visit today, which proves that the county lord must have achieved a little success in the inheritance of the Panlong Palm King, otherwise how could he easily get out of the customs?"

Li Feng smiled faintly.

"Yes, it's a little bit of understanding, but I haven't fought in actual combat, I'm short of an opponent, I thought of you at the first time!"

Yu Siyuan looked at Li Feng with bright eyes and said with a smile.

"This ...... The county lord is a top master among the thirteen young people in the capital, and he is not at the same level as Li at all, so why should it be difficult to be strong?"

The corners of Li Feng's mouth twitched slightly, and Yu Siyuan's eyes made his heart furious.

"Don't pretend, do you think I don't know your strength, come and try it with me!"

Yu Siyuan has already made a move to prepare for a shot.

"Wait a minute, if we go all out here, my dorm will be gone, I don't care, but those roommates of mine will blame me when they come back, so we might as well change places, or lower our strength?"

Li Feng waved his hand again and again, and then said.

"Okay, then go to your academy's Yanwu Square to fight!

Yu Siyuan disappeared into the small courtyard in a flash.

"Yanwu Square, it's over!"

Li Feng cried with a sad face, but he also had to follow.

On the Yanwu Square, the strongest class and the second class of the academy are taking actual combat classes, and the two people who are facing each other now are also the famous top figures in the academy, which are Situ Kaige and Shangguan Liangying.

The average strength of the first and second classes is the strongest existence in the academy, almost indistinguishable from each other, and more than half of the top 100 in strength are from these two classes, so you can imagine how terrifying these two classes are.

Situ Kaige and Shangguan Liangying are the signboards of these two classes, although the former is recognized by more people as the first person in the Dragon Tooth Academy, but Shangguan Liangying never admits this, the two have also fought a few times, although Shangguan Liangying often has a slight advantage, but every time he has not lost to Situ Kaige in a real sense, and the final result is forced into a draw.

At this time, the two had already fought more than a hundred moves, and they still didn't know the winner.

"Shangguan Liangying, this time I will definitely divide the victory and defeat with you!

Situ Kaige roared angrily, and his whole body burst out with dazzling golden brilliance, like a scorching sun, condensing a shocking palm and roaring out.

"I'll definitely win you this time!

Shangguan Liangying's eyes were firm, and his waist-length green silk danced, showing a heroic posture, and between the swings of the green blade in his hand, a wonderful picture of a hundred fairies dancing with flying swords was conjured, and finally a colorful sword light was synthesized, slashing through the air.

Oh!

The sky suddenly darkened, a dragon groan shook everyone's hearts, and a terrifying aura containing the power of heaven swept in, only to see a hovering dragon phantom break through the air, just fell in the center of the two forces, and rolled up a devastating storm, crushing the two forces at the same time.

"What ......"

Situ Kaige and Shangguan Liangying's faces changed in unison, and they involuntarily retreated to the edge of the ring.
