Of course, Sect Master Du knew what his apprentice Du Fei was thinking.

Du Fei is about the same age as Lu Fan, and now that Lu Fan is an outsider, he has become the elder of the Eight Array Sect, which can be said to be extremely noble in front of everyone.

Du Fei is also a competitive person, of course he doesn't accept Lu Fan, so he has to make meritorious contributions in front of everyone now, so that everyone knows that his strength is not much different from Lu Fan.

Mu Tianya saw that Du Fei had to challenge him, and he sneered and was very disdainful.

"Even if you kid still dare to challenge me, your identity and strength are not worthy at all. Defeat this one of my men first! ”

Mu Tianya waved his right hand and immediately ordered one of his subordinates behind him.

"Black servant, you should teach this boy a good lesson, and let the people of the Eight Formations Sect know that their so-called genius is just a waste!" Mu Tianya said.

"Yes, I'll get rid of this kid." The black servant said.

After Du Fei heard this, he was very angry, and immediately clenched his fists and hit this black servant.

Seeing this, the black servant did not panic at all on his face, and he immediately used his fist to hit Du Fei's fist.

When Du Fei's fist collided with the black servant's fist, he immediately felt that his fist was very painful, he didn't expect that the black servant's fist was so hard.

Du Fei has experienced such a long time outside, and he has improved his internal strength and physical fitness a lot, but now he didn't expect that the internal strength of this black servant's martial arts in front of him is similar to him.

Du Fei doesn't believe in evil, he feels that if he can't even defeat this subordinate, then he really has no face in front of everyone.

"Damn, I'm going to beat you!"

Du Fei roared angrily, and he used all his internal strength to attack the black servant.

The black servant's internal force was not weaker than Du Fei's at all, so he didn't suffer at all when he used his internal force to resist Du Fei.

Seeing that he couldn't defeat the black servant for a while, Du Fei became more and more anxious, so he took a step back, and then used a formation.

"Boy, take it!"

I saw Du Fei put his hands together, and then used the internal force of his whole body to input on his hands. Suddenly, a yellow light emanated from his body, and in an instant, his personal ability improved a lot.

Sect Master Du and Elder Chu were immediately stunned when they saw the changes on Du Fei's body, the formation that Du Fei was using at this moment was not the regular formation of the Eight Formation Gate at all. Because the regular formation of the Eight Formations Gate is very limited to improving one's strength, now Du Fei can actually improve his ability so much.

"Hahaha, Sect Master Du, I didn't expect your personal disciple to use the evil sect formation you mentioned!" Mu Tianya suddenly burst out laughing.

After Sect Master Du heard this, he looked at Du Fei again. At this moment, he clenched his fists, and his heart was very angry. He didn't expect that Du Fei would use the formation forbidden by their Eight Formation Gate in order to defeat the enemy in front of him!

"Du Fei, what are you doing? Stand down! Sect Master Du ordered.

Sect Master Du had now determined that Du Fei was using the evil sect formation of their Eight Formation Sects, of course he couldn't admit it in front of everyone, otherwise Du Fei's future would be gone.

"Master, I must defeat this kid and give you a long face!" Du Fei said.

Seeing that Du Fei didn't listen to his orders, and said something to give him a long face, he was eager to dig a hole and get into it by himself now.

After Du Fei's strength improved, he roared, and then attacked the black servant.

Seeing that Du Fei's strength had improved so much, of course he had to be careful. After he dodged Du Fei's move, he also began to use this formation to improve his strength.

"Hehehe, boy, the formation you use can only increase your strength by one or two times, and after this formation is improved by my master, you can instantly increase your strength by three or four times! If you want to learn from me, admit defeat immediately, worship me as a teacher, and I will train you well! The black servant said.

Mu Tianya and the others laughed out loud after listening to the black servant's words. Mu Tianya knew that the strength of this Du Fei was much worse than that of this black servant, so he knew that the black servant would definitely defeat this Du Fei.

"Nonsense, I'll kill you first!"

Du Fei continued to attack the black servant, but this time the attacking servant did not dodge, he used all his internal strength to resist Du Fei.

At this moment, both of them sent out all their strength, attacking each other. But in less than a minute, Du Fei couldn't hold it anymore, and finally he screamed and was knocked to the ground by the black servant.

After the people of the Eight Formations Gate saw that Du Fei was defeated, they were dumbfounded, and then they talked about it.

"Du Fei is the most powerful and talented person in our Eight Formations, I didn't expect to be defeated!"

"Yes, and it was defeated in an instant, it's a shame for us!"

"It seems that the formation of our Eight Formation Gate is indeed quite old-fashioned, and the formation that this Mu Tianya knew just now is so powerful!"

At this moment, Sect Master Du was very angry, he had just gathered the hearts of the people of the sect together, and now everyone began to panic again in a game.

After Sect Master Du walked in front of Du Fei, he then pulled Du Fei over, and he did not use his internal force to help Du Fei heal his injuries.

Du Fei's injury is very serious now, he keeps vomiting blood, and when he saw that his master didn't give him luck, he took the initiative to ask for it.

"Master, I'm very seriously injured now, please hurry up and use your internal strength to help me heal, otherwise I won't be able to bear it!" Du Fei pleaded.

Sect Master Du didn't care about Du Fei's request at all.

"Du Fei, don't worry, you are only injured now and will not die, I can't save you now."

Sect Master Du said: "This Mu Tianya hasn't made a move yet, I have to save my strength to prevent him from making a move!" ”

After Du Fei heard Sect Master Du's words, he was very disappointed and asked to get up again.

"Master, I'm really dying, please hurry up and heal my internal injuries!" Du Fei begged for mercy.

Seeing that Du Fei was still pleading, Sect Master Du whispered in Du Fei's ear.

"Du Fei, how can you have the face to let me spend my internal strength to save you! The formation you used just now is a crooked evil formation that is forbidden to be used by our Eight Formation Sects. Now I didn't deal with you because you were injured, otherwise I would have had people lock you up and deal with it properly. Sect Master Du said.

After Du Fei heard his master's words, he immediately quibbled, he knew that his master was completely disappointed in him now, and he couldn't let this kind of thing happen.

"Master, I'm completely thinking about the reputation of the sect, I just saw that this person's martial arts are so strong, if I don't use some special means, I won't be able to win at all!" Du Fei's tongue is like a reed.
