Professor Mo, who noticed that Situ Xuan was a little strange, didn't say much, he had already seen too much of the unbelievable about Situ Xuan. The breath of the fifth-order peak powerhouse that he released just now, if it was Sun and Liu who were standing in front of him, he would have been severely injured and fell to the ground, but Situ Xuan in front of him just spurted out a mouthful of blood, and he could still stand here with a rainbow of momentum, which is definitely not something that ordinary people can do. However, thinking about it, in the face of a fifth-order intermediate cultivator, Professor Mo still thought that this was nothing at all, at most, it would take ordinary effort, and it would be himself who would win in the end.

Thinking like this, Professor Mo still cautiously controlled the true qi in his body. For fifth-order peak cultivators, their control of true qi can be said to have reached the extreme, their strength is not only reflected in the strength of the true qi in the body, but also in their use of true qi...... However, Professor Mo is not a fifth-order peak powerhouse who has been famous for a long time, but his use of true qi is by no means comparable to Sima Xuan, a fledgling silly boy, and it can be said that Sima Xuan will face a battle to the death.

Although Sima Xuan was very angry when he heard that Situ Futian had also been calculated in the same way, the cautious habits he had developed since childhood made him not carried away by anger at the moment. Professor Mo was the third fifth-order peak cultivator he had encountered in his current position, the other two being Weber and Xingde. For the fifth-order peak cultivators, Sima Xuan had already experienced some from the shock just now, and it was somewhat difficult for him to completely contend with his current self, it seemed that he could only find an opportunity to use the strange tricks in the exercises to kill Professor Mo, and this was the realm of Chongwu Academy, and a long-term battle would definitely attract the attention of many people, if he wanted to fight quickly, suddenly, Sima Xuan's mind remembered the time he fought with Master Mo, a bounty hunter, and the exercises he used when he was on the line of life and death, although those exercises were completely different from his current exercises, but at that time, he used them so well。 Just as Sima Xuan was thinking, Professor Mo's voice came into Sima Xuan's ears, "I'll give you one last chance to hand over the Phantom Thunder Technique, which can ensure that you leave the Martial Capital safely." ”

When Sima Xuan heard this, the corners of his mouth curled slightly, and he said: "Professor Mo, it's not that Situ Xuan can't trust you, it's really that Weber and Xingde will never let me leave easily, so you better dispel your thoughts as soon as possible and come to meet the battle between you and me." ”

Professor Mo snorted coldly and said, "Hmph, I don't know what to do, you really don't know how to do it, you really don't know how thick the sky is, and you actually want to challenge the old man with your fifth-order intermediate cultivation, okay! Since this is the case, then don't blame the old man for bullying people, don't worry, I won't kill you, I will definitely make you give in, and obediently offer the magic thunder trick." With that, Professor Mo's figure disappeared suddenly, and Sima Xuan felt that the space around him was instantly squeezed by a terrifying force, and then he felt a destructive energy attacking towards his abdomen, and the speed was unprecedented for him. Sima Xuan couldn't sit still, he quickly activated the true qi in his body, thickened the protective true qi in his abdomen, and at the same time stepped up and sideways to avoid the path of this attack as much as possible.

"Bang ......" Professor Mo used the energy wave formed by the compressed air of True Qi to hit the ground behind Sima Xuan, although Sima Xuan felt its terrifying destructive power, but the energy wave only left a hole in the ground, and did not cause more damage.

Looking at Sima Xuan again, he was able to avoid the energy wave, his abdomen was not shattered, and there were obvious traces of burning on the right side of his abdomen.

Professor Mo's figure slowly emerged, and he smiled and said, "Situ Xiaoyou, the old man really underestimates you." Don't worry, I won't let outsiders notice the strangeness here, but it's you, but be careful!haha~" With that, he disappeared in front of Sima Xuan again.

Sima Xuan endured the burning pain in his abdomen, and secretly said in his heart: Why does this old immortal always hide his figure, this is not a way to go on like this, he must be allowed to show it. Thinking of this, Sima Xuan controlled the true qi in his body, allowing his true qi to extend to the surrounding space with his perception, in the hope of being able to find Professor Mo's location. However, how could Professor Mo give Sima Xuan the opportunity to discover himself, the attacks of five energy waves in a row made Sima Xuan bruised all over his body, although he had avoided the fatal attacks by thickening the body protection true qi and the displacement of yin and yang, but the speed of the energy wave made Sima Xuan unable to completely avoid it. Moreover, the consumption of physical strength by controlling the true qi for protection is very huge, and Sima Xuan was panting at this moment, and the clothes on his body were already wet with sweat.

In the room, there was only Sima Xuan alone, making people feel as if he was fighting against the air. Professor Mo was very skillful in controlling the true qi, constantly attacking Sima Xuan with compressed air, it was obvious that Professor Mo didn't want to kill Sima Xuan, what he wanted was to destroy Sima Xuan's will and make Sima Xuan kneel to him and beg for mercy. This room is like Professor Mo's torture space, he is like the master of this space, controlling everything in the space, including Sima Xuan's life.

Sima Xuan, who was passively beaten, couldn't hold out for long, but so far, he hadn't found Professor Mo's hiding place, and even if he found Professor Mo's hiding place, it would be difficult to kill the other party with his current state. Today's Sima Xuan can only hope that he can stimulate the potential of the exercises he has cultivated like he did against the bounty hunter Master Mo, and maybe it will be possible to kill Professor Mo at the peak of the fifth order.

Time passed slowly, Sima Xuan was already physically exhausted, and at this moment, he was struggling to support himself by the determination in his heart to kill Professor Mo. And Professor Mo in the shadows had already discovered Sima Xuan's condition, and he knew that as long as he launched another attack, it would be the last fatal straw that could crush Sima Xuan. Soon, Professor Mo launched this attack.

At the same time, at the moment when Professor Mo hit this attack, the perception that Sima Xuan had been building in the room finally let him know Professor Mo's location, but at this time, Sima Xuan had no ability to fight back, and through his perception, he could clearly see the energy wave approaching him again, and finally, Sima Xuan closed his eyes weakly. And Professor Mo in the shadows saw all this in his eyes, and a smug smile appeared on his face. The energy wave hit Sima Xuan in an instant, but the unexpected body flew out, and Sima Xuan's entire body was shrouded in two rays of light, one black and one white, and disappeared into the room.

Although Professor Mo was in the dark, he still saw the whole process of Sima Xuan's disappearance. The two rays of light, one black and one white, made Professor Mo's pupils shrink suddenly, and he said to himself, "Yin and Yang True Qi?!" Professor Mo showed his figure and appeared in the position where Sima Xuan had disappeared, and he carefully felt the changes in the space around him.

At this moment, Sima Xuan gasped and half-knelt in a space, and what happened in that moment kept appearing in his mind. The black and white rays of light were seen by Sima Xuan at the moment before he closed his eyes, if there was a feeling of nothingness, he felt that the black and white rays of light seemed to come out of his body, Sima Xuan looked at his dantian, the original flame had already disappeared, but the two true qi of black and white appeared in the dantian, Sima Xuan tried to urge the black and white true qi, what he didn't expect was that the black and white true qi began to activate in the meridians with his thoughts. At first, the operation was still under Sima Xuan's control, but the faster and faster running speed of the black and white true qi made Sima Xuan feel the possibility of getting out of control. Sure enough, soon the black and white true qi was out of Sima Xuan's control and began to run in his meridians on their own.

The continuous impact of the black and white true qi in the meridians made Sima Xuan feel like he was being bitten by ten thousand ants, and he kept roaring in pain. This period of time is indescribably long for Sima Xuan, and it is also unbearable for Professor Mo outside. Professor Mo had already searched this room several times, not to mention the cracks in the space, and he hadn't even found a trace of Sima Xuan's true qi. This made Professor Mo more and more anxious, the time was close to dawn, and if it was dawn, he would have to leave here.

At this moment, Sima Xuan, who was tormented by the black and white true qi, stopped roaring, and the meridians in his body had also adapted to the speed of the black and white true qi, Sima Xuan slowly stood up from the ground, and a feeling the same as last time made Sima Xuan clearly know that he had entered that state. Sima Xuan slowly raised his hands, the different colors of the two hands surprised him a little, the skin color of one hand turned black, and the other hand was white, Sima Xuan said to himself in his heart: "Is this the price to be paid for this state?" Recalling the painful experience just now, Sima Xuan secretly warned himself: "Never enter this state again unless you have to." Thinking of this, Sima Xuan thought of Professor Mo outside, it was almost time to make an end, now Sima Xuan is the controller of this space, he can control this space freely, naturally it is very easy to know the situation of Professor Mo outside the space.

Sima Xuan made the barrier of the space transparent, so he could see Professor Mo outside. Through the barrier of space, Sima Xuan saw that Professor Mo seemed to be looking for something, and suddenly, Professor Mo looked at him, but he just swept it away, but it didn't take long for Professor Mo to turn back again, and his body shook, and came to Sima Xuan's approach. Sima Xuan was a little surprised, and said secretly in his heart: "Can he feel me?" Just as Sima Xuan was thinking like this, he saw that there was a crack in the transparent space barrier in front of him, and before Sima Xuan could react, the space barrier in front of him was shattered, and at the same time, Professor Mo's slightly old voice also came, "Situ Xuan, I really didn't expect that you would have such a ability, it really makes me easy to find!"

Professor Mo just said outside the space, and did not rashly enter the space where Sima Xuan was. "What, do you plan to hide in it for the rest of your life?" Professor Mo said mockingly, "Don't think that I will have no way to hide inside, the ability of a fifth-order peak powerhouse is far more than what you know!" Speaking of this, Professor Mo clasped his palms together, and the space he was in began to be continuously compressed, and soon the space where Sima Xuan stood began to vibrate due to the changes in the space outside. A cruel smile appeared on Professor Mo's face, and he said, "Do you feel it? This is the true strength of a fifth-order peak powerhouse, if you don't come out yet, I don't mind directly shattering the space on the periphery of the space you are in, and then the space you are in will also be implicated." ”

Sima Xuan slowly floated out of the space, and the moment he appeared, Professor Mo shouted in horror: "It's you! You're still alive! Don't come here......" Professor Mo's roar was mixed with the true qi in his body, and the entire bamboo building exploded for a while, Sima Xuan already had the peak strength of the fifth order at this moment, and the more he surpassed Professor Mo, naturally Professor Mo's roar was useless to him, but for Chongwu Academy, it was not useless to describe, Sima Xuan could feel that the aura of several fifth-order peak strength was moving closer here, Sima Xuan made a decision in an instant, Professor Mo must not be killed, the cultivators of the fifth order peak are not as easy to see as the cabbage in the vegetable market, he just needs to create the appearance that Professor Mo has gone mad and entered the demon meridians and is broken。 Thinking of this, Sima Xuan thundered out, and the black and white true qi instantly burst out from his body, Sima Xuan's mind recalled the acupoint sealing fingering used by Dongfang Yan'er and Dongfang Mingchong, of course, Sima Xuan would not copy the fingering of the two of them, that would cause more trouble. Sima Xuan, who was at the peak of the fifth order, was already able to freely control his true qi to achieve his desired goals.

Sima Xuan compressed the true qi on his fingertips, and then quickly hit Professor Mo's body according to the fingering method of the Dongfang family's sealing acupoints, and did not hit the true qi compressed on his fingertips into Professor Mo's acupoints and meridians, and then Sima Xuan shouted in a low voice: "Break!"

"Poof...... Professor Mo's acupuncture points around his body were all spurting blood flowers, and at the same time, the meridians were also broken, and Professor Mo let out a last terrible roar: "Ah......" fell into the ruins.

At this moment, Sima Xuan also recovered to his original state, just like that time, the true qi in his body was not exhausted, his physical strength was completely overdrawn, and he passed out directly in the ruins. When he fell unconscious, he vaguely saw a beautiful figure running towards him
