After an hour, Mu Heng finally solved the four questions with difficulty for the first time. Of course, it's all Mu Heng's pretend.

I thought that I was not a professional actor, and I didn't know if I could hide it from the other party in such an act.

In Mu Heng's plan, gradually climbing, so that the national teacher realized that it was not easy to solve the problem. In the end, solve four questions at the same time, so that the other party feels that it is difficult to solve the fifth question.

"Great, I was finally able to solve the fifth question at the same time." Seeing that the four formations on the door were lit up at the same time, the national teacher was immediately excited, as if he had already sensed that the Great Yantian Cause and Effect Dao Sutra was already within reach.

"Bang" Just when the national teacher was happy for Mu Heng's breakthrough, there was a loud noise from the enchantment.

Mu Heng, who was in the enchantment, suddenly felt a shaking of the mountains. I was pleasantly surprised in my heart, such a movement must have been caused by Xuanyi's predecessors.

He glanced at the restored enchantment again, although it was not broken, Mu Heng knew that it was only a matter of time.

"There are some tricks." The national teacher turned from joy to sorrow, staring at the place where the enchantment was attacked with a solemn face.

On this side, Mu Heng continued to follow the rhythm of the formation to solve the problem. But then, it was back to the state of "only" solving the third path at the same time.

"Childe, let's solve the problem with heart, my enchantment can't be broken casually." Seeing that Mu Heng was not in the best state, the national teacher was worried that Mu Heng would give birth to a ghost fetus, so he hurriedly warned.

Mu Heng did not reply, but focused on two things, while solving the problem, while estimating the situation outside.

-------------------------------------

On the square, with the blessing of the formation, although the Evil Sword showed a momentum like a bamboo, it did not break the formation enchantment with a single blow.

"I can't break this turtle shell." Liu Qing'er thought that the enchantment would definitely not be able to block this blow, but she didn't expect that she would only let the formation shake twice.

Ye Qingyin didn't expect that after magnifying ten times, he couldn't break through the enchantment, and couldn't help but sigh in his heart: "I didn't expect that the people of the demon clan would study the formation so thoroughly and put down such a powerful enchantment." ”

"Scared the hell out of me." The Dao Tong within the enchantment was so frightened by this momentum that he sat directly on the ground. He was reborn after the catastrophe, and he was glad that there was no danger. He patted his chest and shouted outside, "No matter how you attack, you can't break the barrier of my family, and the monks of the human race are just like that." ”

"But there's still a way?" Liu Qing'er frowned, ignored Dao Tong's taunt, and asked Ye Qingyin. She remembered Mu Heng in her heart, but she couldn't show it obviously, and the blow was ineffective, which also made her a little anxious.

"Please also ask the seniors to try again. This time, the seniors can attack from another place. Ye Qingyin couldn't think of a more effective way for the time being, so he could only try again to see the effect and the reaction of the enchantment.

"Okay." Liu Qing'er replied casually. Then close your eyes tightly and adjust yourself to the best condition.

Everyone returned to their original positions and repeated the formation again, increasing the Evil Sword Sword.

Liu Qing'er suddenly opened her eyes and continued to infuse the Evil Sword with spiritual power. The stimulated Sword of Evil once again flashed with brilliance, and a sword shadow similar to its shape appeared on the sword.

"Go." Liu Qing'er held the Evil Sword, and a sword technique with an outer wrist stabbed forward. The sword shadow then detached from the tip of the sword, cutting off all the aura around it, and rushed towards the barrier. This time, the place where the sword shadow attacked must have moved down the distance of the previous battle.

The "boom" was louder than the last time, and the huge energy impact caused the ground to tremble, and everyone was affected and unstable on their feet.

"Hey, this time it seems to be a bit louder than the last time." Liu Qing'er could clearly feel that the second attack seemed to be more effective, and she couldn't help but be a little curious.

-------------------------------------

Mu Heng in the enchantment kept calculating the questions, and at the same time focused on the movements on the enchantment.

There was a loud noise in his ears, it seemed to be worse than the last time, and Mu Heng guessed that Ye Qingyin and they must also be looking for a way to break the barrier.

The difference between the two sounds is not only in volume, but also in position. The impact of an attack can also vary considerably.

Such a scene couldn't help but remind Mu Heng of the escape window set up on the train in his previous life. There is always a sharp hammer pinned to it, and there is a warning next to it: it should not be used unless it is an emergency.

To escape, you need to smash the glass with a sharp hammer to break the escape exit. And this sharp hammer smashes glass, but it is a learned job.

Based on the fragility of the middle of the glass by default, most people will choose to smash the middle directly. However, this is not the case, and it is easier to break by smashing corners.

This is because glass has a certain toughness, and the stress is relatively small when it is smashed in the middle, and it is difficult to form a target. When smashing the corners, because the edge of the glass is constrained by the window lintel, it is easy to form a stress concentration, and the glass is more easily destroyed.

Mu Heng felt that the barrier at this time was similar to a glass cover, the more middle it was, the more elastic it was, and the more difficult it was to break it. On the contrary, the basic position of the formation enchantment, especially the place where it is constrained by force, is the most advantageous position to break the enchantment.

Mu Heng wasn't sure if Ye Qingyin outside was aware of this, and couldn't help praying in his heart that Ye Qingyin could sense his thoughts.

Outside the enchantment, Ye Qingyin stepped forward to check that there was a big difference in the effects of the two attacks, and carefully analyzed the difference, trying to find out the crux of the problem.

I don't know if it is related to Mu Heng's heart, Ye Qingyin flashed a glimmer of spiritual light in his mind, as if he had grasped the key.

"Senior, I think I know how to break this barrier." Ye Qingyin smiled slightly and said to Liu Qing'er.

For the sixty-fifth time, Mu Heng continued to solve these four questions at the same time, and the time came to the twenty-fifth second.

The third loud "bang" came from a lower place outside, and it seemed to have a devastating potential, which was much more powerful than the previous two reactions.

The ground under his feet shook uncontrollably, like an earthquake. Mu Heng's heart lit up, and the meaning of ecstasy surged into his heart, and he looked at the following national teachers from the corner of his eyes, and saw that he was also attracted by this fluctuating quiet, and seemed to be a little confused.

Waiting for thousands of times is waiting for the national teacher to divert his attention. Mu Heng secretly said in his heart: "The opportunity has come, it is now." ”

Saying that it was too late, Mu Heng hurriedly stretched out his other hand, inserted the fifth formation, and entered a fractional value into the formation.

The time came to the twenty-ninth second of the fifty-sixty-fifth time, and with the activation of the fifth formation, the entire positive pentagonal gate suddenly disappeared out of thin air.

Mu Heng seized the remaining last second, and pushed his body into the pentagonal door.

Thirty seconds, or three breaths later, the pentagonal door appeared out of thin air, and the five corners were re-locked.

"Sure enough." Mu Heng looked at this scene, and his hanging heart finally let go. Before, Mu Heng felt that the time control of these three breaths was very peculiar, so he thought that there must be a necessity for him.

Thinking of the things hidden behind the things that I figured out before, the people behind it must only want to have a person who is destined to obtain the Great Dao Sutra, so there must be some arrangement, and it should be on the unlocking of the five locks on this door.

Sensing the strangeness of Mu Heng's side, a bad premonition rose in the national teacher's heart, and he turned his head to look at Mu Heng, who was already behind the door.

The anger from ancient times surged in his heart, and the resentment generated by thousands of years of waiting and groping was all released. The national teacher's face was suddenly red, and he didn't have the heart to care about the current situation that the enchantment had been broken, so he jumped directly to the pentagonal door, looking at Mu Heng inside and jumping to his feet angrily.

"You.. You.." The self-proclaimed intelligent national teacher knew that he was put on the side by Mu Heng, and infinite remorse and pain came to his heart.

"Ahh The national teacher was eager to eat his flesh and drink his blood, and pushed forward with both palms, and a huge storm flew out of his palms, and two pillars of wind rushed towards Mu Heng's position with great speed.

Unfortunately, the formation on the pentagonal door is not only a lock, but also a protection, keeping this storm out.

Seeing that the trick didn't work, the national teacher's hands turned into stone fists, and with all his strength, he slammed the door hard.

"Boom. Rumble.. Boom.." The incessant sound of slamming the door seemed to have the power of ten thousand catties, and where the stone fist came into contact with the door panel, sparks actually appeared.

Mu Heng behind the door touched his chest, and his heart was raised again, worried that this door panel would not be able to withstand such a violent beating by the national teacher.

"Ahh Xuanyi seniors, real people, you are finally here! Noticing that the Xuanyi seniors in front of him, who were dressed in Xuanqing coats and wrapped in veils, led Ye Qingyin and Xingyin who carried Daotong, and other female disciples rushed in, for a while, Mu Heng felt a thousand steadfastness in his heart, and felt the concern of his family.

"Demon, don't stop it quickly." Liu Qing'er saw that Mu Heng, who was behind the door, was safe and sound, put her mind at ease, and shouted to the national teacher in a loud voice.

"Haha, a thousand-year calculation was destroyed in the hands of your little doll, I hate it." The national teacher didn't seem to take Liu Qing'er and them in his eyes, stopped the movements in his hands, looked up to the sky and laughed, and the laughter contained helplessness and desolation.

Mu Heng looked at such a national teacher, and suddenly felt a little soft-hearted. However, when I thought of the hostility between the demon race and the human race, I put aside this little sympathy.

"We should be glad that the treasures of the human race have not flowed out." Mu Heng said secretly in his heart. Glancing at Ye Qingyin and them, Mu Heng shouted in their direction: You deal with it here, I'll deal with something first. ”

After speaking, he raised his feet and walked towards the door, leaving Liu Qing'er and them to deal with the national teacher. His own side also has the Liangyi Realm, and with the assistance of the disciples of Yuqing Xingzhai, he should not suffer a loss.

When the national teacher heard this, his eyes widened as big as copper bells, and he stared at the direction where Mu Heng disappeared with hatred.

Liu Qing'er looked at the national teacher who seemed to have lost his mind and went crazy, and didn't understand why he showed so much hatred for Mu Heng, and wondered if Mu Heng had done something terrible again, causing this national teacher to lose his temper so much.
