With this success, Mu Tian even had an even more crazy idea, that is, the heart is divided into four uses or even multi-use, in that case, if he cultivates the exercises of his own global system together, it is estimated that the cultivation progress of one day can be compared to the cultivation of others in several years. 【Fengyun Reading Network.】

However, although the way of heaven is unfair, it is because God does not allow an existence that surpasses it, if Mu Tian can really use more than one heart, it is estimated that a thunderbolt from heaven will kill him to the slag.

If there is no knowledge of the existence of the Taiji Diagram in the sea, Mu Tian's heart will be a little difficult to use for two purposes, not to mention multi-use, although this idea is tempting, but under the premise of not challenging the strength of the heavens enough, he has to be buried deep in his heart.

Nowadays, the heart is divided into three uses can make all domain people feel ashamed, and blindly pursuing this limit is obviously breaking the rules of the game.

The three uses of the heart did have an incalculable benefit to his cultivation, and within a moment, Mu Tian felt that the domain power in the dantian was stirring up again, and it was time to start compressing.

The soul merged into one, completely blocked the dantian, and did not allow the slightest overflow of energy, and began a slow and painful compression process.

Whenever a line of space appeared in the dantian, Mu Tian immediately separated a divine consciousness and continued to increase the infusion of energy, and so on, he finally felt the ultimate meaning of "pain and happiness".

This situation lasted for three months, during this period, Mu Tian had to go to Leng Hui to "treat" after the end of his cultivation every afternoon, with the injection of soul, Leng Hui was no longer as sluggish as before, and he was able to recognize his grandfather Elder Leng, which made the old guy overjoyed, and he was more polite to Mu Tian, of course, these were deliberately done by Mu Tian, with "Regent" and "Soul Control" The two soul skills, no matter what Leng Hui asked for, he had to obey obediently, and there would be no resistance in the slightest, and now he was equivalent to half a puppet of Mu Tian.

Sun Tzu's condition has improved greatly, Elder Leng has a lot of respect for Mu Tian, and he also greatly appreciates this kid's ability, and the relationship between the two has gradually eased a lot, and everything is developing towards Mu Tian's thinking.

There was no such hostility between the two, and Mu Tian also asked Elder Leng some cultivation questions from time to time, and he was very relieved that he appreciated Mu Tian's tireless attitude, and he also knew everything about the questions raised by Mu Tian, and put forward a lot of pertinent suggestions.

Tomorrow is about to be a new round of qualifiers, and Mu Tian asked the question that had plagued him for three months, that is, the question of the strength of the students of Tianyuan Middle School.

Elder Leng did not doubt him, and slowly revealed the secret.

It turns out that there is a great difference between the Heavenly Academy and the other three courtyards, and the difference lies in the energy in the practice room.

Although the energy in the Diyuan and the Xuanhuang Second Courtyard is rich, there is a hodgepodge of all the energy inside, while the Heavenly Courtyard is different, the energy in its practice room exists in the form of a single system, that is to say, students who enter the Heavenly Academy to cultivate can choose a special practice room according to the domain system exercises they are cultivating, so as to avoid the possibility of being disturbed by the energy of other systems.

Therefore, the real purpose of the existence of the Heavenly Academy is to make the final preparations for the breakthrough of the monarch-level powerhouse, and the breakthrough of the Domain Emperor requires a large amount of domain power as an aid, which requires the domain person to compress the domain power in the dantian as much as possible, and the fastest and best condition is to be able to cultivate in an environment where the energy of the domain system is strong.

Before breaking through to the Domain Emperor, the more domain power a domain person has in his dantian, the faster his cultivation speed will be in the future, and the higher the realm he can reach, for this purpose, the existence of the Heavenly Academy is to enable students to reach the limit of the domain power that their own dantian can hold before breaking through.

This also directly led to the particularity of the students in the Heavenly Academy, they forcibly did not break through, but frantically compressed the domain power in the dantian, so there was the scene that Mu Tian had seen before, the strength of the peak students of the Heavenly Academy was obviously one line higher than that of the students of the same level in the Heavenly Academy.

Elder Leng also warned Mu Tian that the Heavenly Courtyard was the best cultivation place for those at the peak of the monarch rank, if it was possible, don't try to break through before leaving the Heavenly Courtyard, those domain emperor-level powerhouses in the Heavenly Courtyard actually entered after breaking through from the Underground Courtyard.

This news undoubtedly shocked Mu Tian, and after inquiring in detail, he learned that some students had already compressed the domain power in the dantian to the limit of what they could bear when they were cultivating in the underground courtyard, and they made a helpless move after being hopeless, except for a very few of these students who were extremely talented, most of the others had mediocre qualifications, and if they didn't break through, they would not be able to enter the heavenly courtyard with their strength at all.

And although the Heavenly Academy is the best place to cultivate at the monarch level, its single-line practice room also has great benefits to the Domain Emperor, and cultivating in it is of course faster than in other places.

According to what Elder Leng said, each student can cultivate in the Outer Four Academies for four years, and after four years, according to their own wishes, those who are willing to stay in the Outer Four Academies can become a teacher in the academy as long as they pass the assessment of the elders, just like the iron tower, but the teacher is not qualified to continue to enter the four academies to cultivate, and only after passing the assessment again and advancing to a quasi-elder can he regain the qualifications of the student period.

The quasi-elder is an elder if he goes further, and when he reaches this level, he has some privileges, of course, as for what privileges Elder Leng will not say.

But under Mu Tian's stubborn stalking, Elder Leng also revealed to him a little bit of the elder's situation, the academy has a total of ten elders under the dean, and it is the survival of the fittest, the number of elders remains the same, if there is a strong quasi-elder, there will be someone among the elders who will face the danger of being eliminated, so this is also an extremely challenging position.

Under Mu Tian's inquiry, Elder Leng revealed his rank among the elders, Seven Elders, this news undoubtedly shocked Mu Tian's little heart again, with the strength of Elder Leng Domain Emperor's peak, he was only a Seven Elder, and the six on it were not even more powerful, and the mysterious Dean had reached that realm.

These news made Mu Tian feel like he was sitting in a well and watching the sky, this was a branch of the Nine Great Powers Domain Academy, just the tip of the iceberg, it made Mu Tian feel invincible, so how strong was the overall strength of the Domain Academy.

In his heart, he couldn't help but re-evaluate the strength of the nine major forces, and at the same time, he secretly made up his mind that he must make full use of this precious time in the outer four courtyards to bring his dantian to a limit that others can't reach.

Continuing with the above topic, those who are willing to stay in the academy are not mentioned for the time being, and students who are unwilling to stay in the academy have two choices, one is to leave the academy directly, and the future path depends on everyone's ability, whether they live or die has nothing to do with the academy, but if the academy is in trouble, these students have the obligation to return to the academy to contribute to the cultivation of him.

Another option is, of course, to enter the Inner Four Courtyards to continue cultivating, but if you want to enter the Inner Four Courtyards, it is not so easy, in addition to the requirement that the Iron Tower said before to stay in the Heavenly Courtyard for four ring qualifiers, you also have to face an assessment by the elders, and only the winner is eligible.

And the strength of the elder Mu Tian has already seen it, now he is facing the cold old man who is only the seventh elder, and he can't support it for a moment, not to mention other elders, the elder's assessment is also based on people, the stronger the strength of the student, the stronger the elder to face, with Mu Tian's qualifications, it will definitely not be the cold old man The seven elders he will face at that time, it may be the five elders, or even the great elder directly.

These are all analyses made by Elder Leng according to Mu Tian's situation, and there is absolutely no exaggeration in the slightest, which undoubtedly makes Mu Tian feel like he has fallen into an ice cave, facing the Great Elder, does he have hope, and his heart is full of bitterness.

It turns out that what the tower said at the beginning was not detailed, and it is estimated that he didn't want to hit these newcomers who had just entered the academy

Mu Tian thought about it for a while, it was less than four years before the opening of the forbidden realm, and only those who entered the domain courtyard were eligible to enter the forbidden domain, and to enter the domain courtyard, they had to cross the level of the inner four courtyards.

Therefore, there was not much time left for him, and according to his plan, he had to enter the Inner Four Courtyards within a year, no matter how much the domain power was compressed. Although the cultivation conditions in the Heavenly Courtyard were indeed attractive, as a higher level of the Inner Fourth Courtyard, it must be one level higher than the Outer Four Courtyards, and it must be a good choice to cultivate there.

Time is tight, the task is heavy, this is indeed a problem that needs to be solved urgently, it seems that tomorrow's qualifier must win, there can be no slack.

With a sigh, with the light vibration of the futon, Mu Tian walked out of the gate of the underground courtyard.

The students on the road looked hurried, and they seemed to be in a hurry to make the final preparations for tomorrow's promotion competition, this kind of competition is not willing to refuse, and being able to advance means that there will be more superior cultivation conditions waiting for them.

Standing near the mysterious tower, Mu Tian had a new understanding, because he got a message from Elder Leng that made him unable to calm down in his heart for a long time, that is, this mysterious tower was actually the inner four courtyards.

He had been racking his brains to know the secret of the tower, and wanted to know the specific information of the Inner Fourth Courtyard, but he didn't expect that the secret was close at hand, and there was nowhere to find it when he stepped on the iron shoes, so it didn't take any effort to get it, no matter how he guessed, he didn't expect that this was actually the Inner Fourth Courtyard.

There is a courtyard in the hospital, which is indeed incredible, but the facts are in front of him, and he can't help but believe it.

As for what the situation was in the tower, that is, in the inner four courtyards, let Mu Tian say all the good things, and even use the bait to cure Leng Hui as soon as possible, Elder Leng refused to reveal the slightest.

Although the old guy loves Sun very much. Although Chong Guan was angry and wanted to destroy Mu Tian to vent his hatred for Leng Hui, but after calming down, he still had some "professional ethics", the secret of the Inner Four Courtyards was not something that could be easily known, because this was the place where the Domain Academy cultivated the strong, and it was the secret to strengthen the strength of the Domain Academy, unless Mu Tian could enter it or become an elder of the Outer Four Courtyards, it would be impossible for him to know.

And the students who enter it also have a rule, and after they come out of it, they will either join the Domain Academy and become a member of it, or keep this secret in their hearts forever, otherwise if the Domain Academy finds out that someone has revealed the secret to other forces, they will have to face the pursuit and killing of the strong people of the entire Domain Academy, and they will not die.

And this regulation has existed for 10,000 years, and there has not been a single accident in it, so it is conceivable that the secret of the Inner Four Courtyards is a taboo in the hearts of those students who have entered it, and it can also be seen that the strength of the Domain Academy is strong and domineering.

Surprised, Mu Tian stepped over the tower and walked towards the small courtyard, knowing that this was the inner courtyard, he had no interest in continuing to explore, anyway, he would be one of them in the near future.
