After the time for class came, Wei Sihan and Shang Zhengyang chatted with Yu Fei about some inconsequential things, Yu Fei didn't say anything to them because he was going to deliver the letter, and after saying goodbye to the two, he walked towards Huang Yiban alone. Still passing by the very familiar and terrifying stone carving, Yu Fei still couldn't help but take a few looks, he didn't dare to get close to it anymore, because the feeling he had last time was that the infinite spiritual pressure from heaven and earth made his soul tremble.

"Let's hurry up, this is a real immortal, if you are in a bad mood and itchy somewhere, I guess I will be bounced to death by him as a flea." Yu Fei thought to himself, but his pace still accelerated, and he walked and walked, and as a result, he bumped into a person. It's a common thing to bump into someone, but he's different. That person was arrogant, completely arrogant and unreasonable, and directly stopped Yu Fei with one hand.

"Hey, boy, you don't have long eyes when you walk, do you know if you hit someone?" The man was very arrogant, Yu Fei looked up, and suddenly became a little annoyed, obviously the other party deliberately hit himself, but he said that he hit him, which made him angry. Then he said angrily.

"The road is facing the sky, each side of the road, you hit me by yourself, are you embarrassed to say me?" Yu Fei's words immediately attracted the eyes of countless people, and the people around him took a closer look, yo! Isn't this Yu Fei's classmate from Fengyun Academy? This is okay, one by one, they all came over to see the excitement. As soon as the man saw that it was Yufei, he was stunned, then laughed, and then said with both hands in his fists.

"It turned out to be Yufei's classmate! Disrespectful and disrespectful! Recently, your reputation can be said to be known to the whole hospital, but you just bumped into me, so this matter will have to be taken care of today. In the fourth order of the Niu Hammer Qi Refining in the Second Class of Xiahuang, I heard that many people want to challenge you, I don't know if you are free today?" Yufei was a little displeased when he heard it, why did someone look for something as soon as he went out?

"I'm not free!I'm going to Huang Yiban!" Yufei wanted to leave after finishing speaking, but he was stopped by a bull sledgehammer just after taking two steps.

"That's not going to work! I wrote you a challenge book before, just to ask you to come out and touch it, and who knows that before you could finish it, someone tore it up in half. Since you haven't received the letter, then I will now formally challenge you, and today you have to agree to it, and you have to agree if you don't agree. "Wang Da Hammer is this iron heart not to let people go, Yu Fei is completely angry, it seems that if he doesn't kill chickens and monkeys today, this matter may be endless in the future. Yu Fei smiled evilly, then slowly took a few steps back, and then said.

"No problem, but you'd better use your strength, or I don't know how many seconds you'll be able to hold on. After saying that, Yu Fei took out the pan. After hearing this, Niu Sledgehammer's momentum suddenly rose, and finally he got his wish.

"Hey, hey, I heard you're crazy, I didn't expect you to be so crazy! After the battle dance mad !! finished speaking, the aura in Niu Sledgehammer's body began to flow continuously, and then the powerful momentum began to climb steadily, and a fourth-order Qi refining cultivation broke through the entire square, and then everyone was startled. I saw that his momentum was still rising, a spiritual power slowly wrapped his whole body, and his muscles began to slowly bulge, like a muscular man, all of a sudden his body grew half a meter taller, at this time Yufei looked at the transformed ox sledgehammer, and suddenly...

"I'm rubbing! It's so cool! Can anyone tell me how to cultivate? I want to learn !!" As soon as Yu Fei said this, everyone in the audience immediately fell to the ground, but the bull sledgehammer on the opposite side didn't make the first move, he first felt the power of the muscles all over his body, and then he took out a hammer from the ring, yes, it was really a hammer. However, the hammer he used, which weighed thousands of pounds, was a magic weapon. After Yu Fei glanced at it, and then looked at the pan in his hand, his heart suddenly darkened.

"Haha! Yufei, do you know that I can complete the abuse of the eighth-order powerhouse in my current state, but there are more sequelae, and I didn't want to use it, but now that I meet you, then I have to attack with all my might, after all, you are the one who escaped from the hands of Senior Sister Murong Qi, so I'm sorry." After Niu Sledgehammer finished speaking, Tai lifted the two-meter-long sledgehammer, and then won with white light, and an indescribable momentum overwhelmed Yu Fei. Yu Fei didn't move, but lowered his head and looked at his pan. Everyone held their breath after seeing this scene, Yufei was so big, just waiting for the bull sledgehammer to attack like this, so what is it not looking for death?

"The first taboo of war dance madness, flying sand and stones!!" Ox sledgehammer is a big move as soon as he comes out, he was still running, after speaking, his whole body began to spin, and before he had time to breathe, his whole person was like a spinning top spinning wildly, and when he reached the fastest speed, he smashed towards Yufei. Yu Fei still didn't move, still looking at his frying pan, but at this time, he exuded a very tyrannical aura, and the people around him seemed to sense that something was wrong and avoided it. When the ox sledgehammer was less than a meter away from Yu Fei, Yu Fei finally raised his head, looking at the bull sledgehammer in the sky like a tornado, Yu Fei's eyes shot a cold light, and then the black pan he was holding suddenly turned red, then golden, and then turned into a fiery red color.

"You are strong, you are strong, you are strong!Flames!Explosions!" Yu Fei just recited two incantations in his mouth, and then when the hammer of Niu Sledgehammer was still one centimeter away from his face door, he only heard an extremely harsh and violent explosion, and everyone only saw that Yu Fei was holding a hot fiery red frying pan, and slapped it towards the hammer of Niu Sledgehammer, and the hammer of Niu Sledgehammer seemed to have been hit by a train, and it was fixed in place, when Niu Sledgehammer looked at this scene in disbelief, suddenly, a terrifying aura emanated from his hammer, and it was too late for Niu Sledgehammer to go to see it, only to see the back of Yu Fei's pan, which suddenly exploded, A thunderous sound directly swept the whole body of the cow sledgehammer, the cow sledgehammer was like being hit by a truck, the body flew out directly, just as soon as it landed, another explosion came out, a flame-like breath wrapped the cow sledgehammer, and then a bang, the ox sledgehammer exploded from the ground again, and finally when it landed, the body had changed back to the original, but at this time he was covered in blood, and all the clothes on his body seemed to have been burned by fire.

"Grass! The name of the skill is better than mine, and even the magic weapon is better than mine, you still dare to challenge me, and you are still showing off in front of me, unforgivable! I don't beat you, who am I beating?" Yu Fei was really angry, just now, due to the extreme instability of his emotions, the spiritual power in his body finally broke through the boundary and rushed directly to the fifth level of qi refining, but no one noticed how he did it. At this moment, Yu Fei broke through again and successfully advanced to the fifth order of qi refining, but unfortunately, the time watch did not give him any reward at all, in fact, he himself could figure it out, the last time he broke through, he could already advance to the fifth order, but he lost everything, otherwise he would not be able to advance to the fifth order so easily.

"It turns out that to break through the fifth order, you need to use your own perception and extreme emotions. Yu Fei finally understood what was going on, he glanced at the blazing pan roasted by the fire spell, and couldn't help laughing, it turned out that the power released by the spell using the magic weapon would be so powerful.

"Battle evaluation: Use the fire technique to burn the pan, float on the surface of the body with the explosion technique, and release the two techniques at the same time at the moment of contact, not only to achieve the power of blocking the jack hammer, but also to use the super rebound force of the explosion technique to bounce it back, and finally the explosion technique is attached to the body surface of the ox sledgehammer, completing the final hammer, and the battle score SSS. Congratulations to Yufei for successfully creating his own skills, do you need a naming word?" At this moment, the Time Watch gave a series of data, and after Yufei read it, he turned it off directly. This kind of thing can change at any time, and there is no need to use it.

And Liu Wenbo, who was watching the battle from a distance, suddenly clenched his teeth tightly when he saw this scene, he would never have thought that Yu Fei had really broken through at this time and had successfully advanced to the fifth order, and he himself carefully observed everything that had just happened, and he asked himself if he went to catch the fatal blow of the bull sledgehammer, he would definitely be able to block it, but it would definitely not be so easy.

"It seems that we have all underestimated this fourth-order Qi refining classmate, oh! no! it should be the fifth order of Qi refining now. I just don't know what other surprises will be waiting for us?haha!" Jiang Qinzi happened to see this scene and couldn't help laughing. He is now more and more optimistic about this, his cultivation is not very good, but the strength is not weak, if he doesn't watch carefully, he can't believe it, this guy is an intermediate spell as soon as he makes a move, and it is the best kind.
