On the day the advanced class entered the academy, the academy did not arrange any teaching, but let them relax a little, by the way to adapt to the new living environment, and also to allow the students to communicate with each other, after all, in Nangong Jue's opinion, some of them must become comrades-in-arms of the new special combat team in the future.

Of course, maybe in the entire refresher class, even including Situ Zhentian, no one knows Nangong's true purpose, this refresher class is to put it bluntly, it is for Lin Zichen alone, in order to let him select the elite and create the strongest special combat team.

But the most ridiculous thing at this time was that the chief instructor of the Eastern Academy was still in the Seven Holy Mountains, and he had no intention of leaving.

On the top of a peak in the Seven Holy Mountains, Lin Zichen had completely forgotten himself, and after the wood and fire rune breath was completely injected into the rune stones, he had already begun to refine under his control, he put aside the two rune stones full of rune breath, and immediately stimulated the rune stones with his true qi, so that the rune breath and his true qi slowly became acquiescing.

After a short period of refining, I saw a faint light appear in the originally dark Vientiane space, one side was pale green, and the other side was not pale yellow, although the color was not deep, and the light was not dazzling, but Lin Zichen smiled with relief, he knew that the real construction of the Five Extremes Rune Array had begun.

However, according to the five extremes of mutual restraint, the wood system and the fire system will be the easiest refining stage, Rao is so, it still makes him feel that he has done his best, maybe after refining this stage, I am afraid that he will have to improve his strength before he can carry out the next step of refining, otherwise it will be difficult to control the refining of the rune breath of the two attributes of earth and gold.

In the next two days, Lin Zichen was still refining, completely forgetting about the refresher class, and after two days of tactical teaching, the evaluation of this chief instructor Lin became more and more negative.

However, Situ Zhentian was very satisfied with all this, for the first time, he felt that it might be a good thing that this Lin Zichen did not follow the rules, the old gentleman and Lin Yuan spoiled him on weekdays, but these students definitely not.

These trainees are the dragons of the people in various military regions, and after being selected into the special combat team, they are still the trump cards in the team, no one is smaller than anyone else in terms of temper, and they are all well-known figures in the army in terms of fame, how can they endure this cultivation promotion instructor who has never appeared?

Executive Yuan, Nangong Jue sat at the desk and was also a little worried, he didn't want to disturb Lin Zichen's retreat, but it has been two days since the refresher class started, and if this instructor doesn't show up again, I'm afraid he won't be able to say it, not to mention that he has delayed teaching, at least he has lost the time to select team members.

"Old man, if Instructor Lin doesn't come back...... Are we considering a different choice? At present, the mood of the trainees in the refresher course is relatively unstable, and some people have already put forward their opinions on the improvement of the training for two days after the first two days of the class. Lin Gang said helplessly.

Nangong Jue sighed and said, "Hehe, do you think there is a second person besides Lin Zichen in the Occult Academy who can do it?" The strength of these refresher class students is not as simple as the students of the East and West Academies, who taught him but him? ”

Hearing this, Lin Gang also sighed: "That's true, but ...... But you can't delay teaching. ”

"Well, Lin Yuan, you go and calm the students' emotions first, and I'll figure out a way to do this."

"Okay, old man, I think we should take precautions first, we have applied for this refresher course for so long, a total of a month, and it has been delayed for a long time...... I'm afraid the top management will also be unhappy. ”

Nangong Jue nodded: "Indeed, I will contact the monkey cub." ”

After Lin Gang left, Nangong Jue left the Executive Yuan directly, went straight to the Seven Holy Mountains, and quickly searched for Lin Zichen's location with his perception, and couldn't help but smile: "Monkey cub, it seems that you have reached the middle stage of metamorphosis when you actually go to such a deep mountain to cultivate." ”

After that, Nangong Jue rushed up and rushed directly to the peak where Lin Zichen was, his breath was very light, for fear of disturbing Lin Zichen, so he immediately sat on a mountain rock, feeling Lin Zichen's breath.

In the Vientiane space, the initial refining of the five-pole rune array has reached the most critical time, the moment the wood and fire are blended, the wood makes fire, but the fire is not wood, so the fire runes in the array have been very stable after refining, but the wood rune stones are difficult to exist in the array.

The five-pole rune array is made of five kinds of rune stones full of breath suspended in the east, west, south, north and middle of the array, so in order to make the rune stones permanently suspended in the array, it needs to be assisted by the breath of mutual life, or the martial artist's own true qi is forcibly stabilized.

At this moment, Lin Zichen almost completely relied on the power of his True Qi to stabilize the Wood Rune Stone in the array, which not only consumed a large amount of True Qi, but also had great strength, otherwise it would be difficult to do it at all.

However, Lin Zichen felt that although the sea of qi was constantly pouring out true qi for his own use, he was still one point short of strength, and every time the wood rune stone was about to hang in the array, it would fall down because of the difference of one part of force.

"If this attempt doesn't work, I'm afraid I'll have to wait until the late stage of the Transformation Realm to refine it, and the true qi power in the middle stage will always be a little worse." Lin Zichen took a deep breath, let the sweat drip from his face, and once again concentrated all his spiritual and true qi power on the wood-based rune stone.

However, the familiar scene finally reappeared, and the wooden rune stone trembled in the space a few times, and the original light dimmed, and then fell downward.

Lin Zichen shook his head, it seemed that it was really difficult to stabilize the rune stone with the current strength, although he was very helpless in his heart, he could only try again in the future.

But at this time, Lin Zichen's whole person was stunned, only to see a strange true qi suddenly break into the Vientiane space, that true qi seemed to be soft but full of inner tenacity, obviously it did not belong to him.

Lin Zichen couldn't help but instinctively become vigilant, was he stumped to be sneak attacked? Is it human? Is it a strange beast? At this moment, he was rarely really panicked, and subconsciously wanted to rush his divine soul out of the Vientiane space, but when he saw the moment the true qi rushed towards the wooden rune stone, he couldn't help but be surprised again.

I saw that the true qi rushed to the bottom of the wood-based rune stone, completely combined with the true qi he originally exuded, it was at least two percent stronger than the original, and these two percent seemed to be enough to make up for the one percent of the strength that he had to control the wood-based rune stone.

Lin Zichen simply doesn't care about the source of this true qi, now is the best opportunity to refine wood and fire rune stones, you must not miss it, even if it is dangerous, you have to break through, and this is the power of a martial artist's desire for power!

In about half an hour, the falling wood-based rune stones began to rise slowly, and when they reached the same height as the fire-type rune stones, they gradually stopped, and the two true qi intertwined in the space, forming a powerful force to completely stabilize it in the space.

This kind of stability was carried out for about three or four hours, and Lin Zichen saw that the wood rune stone emitted a powerful green light, bright and dazzling, he couldn't help but smile, it's done!

Although this is only the beginning for the Five Extremes Rune Array, it is already a miracle to be able to refine successfully, after all, it is obviously impossible to achieve it with Lin Zichen's current strength, if it weren't for the appearance of that strange true qi, his result today would definitely be a failure.

However, Lin Zichen also saw that the difficulty of refining the Five Extremes Rune Array was really not small, and now in the middle of the Mortal Realm, it was actually difficult for him to carry out the initial refining, if it was in the middle and late stages, that kind of difficulty would probably be unimaginable now.

In addition to the excitement, he remembered that he still didn't know where that true qi came from, he withdrew his soul, slowly opened his eyes for a moment, and couldn't help but laugh in his heart.

And facing him was Nangong Jue's smiling face.

"Old gentleman."

"Zichen, you are really good enough this time, you didn't show up for three days after the refresher class started, but you mostly retreated here to practice the formation." Although Nangong Jue also had some complaints in his heart, he would not accuse Lin Zichen after all, after all, when he promised Lin Zichen that the courtyard had no rules for him, he was already destined to rely on this little guy in everything.

However, Lin Zichen also truly appreciated Nangong Jue's strength, he was able to enter his Vientiane Space with his true qi and find himself refining the array, and he could also help himself with his true qi, this strength must be above himself.

Of course, as for what Nangong Jue's strength is, he doesn't know, and now Lin Zichen can only evaluate Nangong Jue's strength as unfathomable.

Lin Zichen sneered and said, "Old man, I'm really sorry, Zichen didn't know that the refining process would be so long, and the teaching was delayed......"

"Hehe, forget it, the old man said that there are no rules for you Lin Zichen, you can go back now?"

Lin Zichen smiled and nodded: "Yes, thank you, old man, if you hadn't helped me just now......"

"Use your energy on the special combat team, these trainees are not easy to deal with, everyone is arrogant, you have to be a little mentally prepared." Nangong is desperate.

"Yes, don't worry, sir, I'm not worried about this, but...... Zichen still wants to know, how many places does the old gentleman plan to give me in this special combat team? ”

Nangong Jue smiled: "That's not up to you, but as long as it's confirmed, try not to change it, because the establishment of this special combat team is very strict at the top." ”

Lin Zichen nodded knowingly: "Understood." ”

Early in the morning, in the open space of the Yuquan Mountain Pass, more than 40 students of the advanced training class stood in line, and when they heard that the cultivation and improvement teaching was going to be carried out today, many people were quite surprised, after all, they thought that the instructor would not appear at all this time.

"Hehe, this instructor didn't start classes until three days after entering the hospital, what a big shelf."

"yes, what are you doing with us? Do you really think you're the pride of the sky? Cut, apart from Chief Instructor Situ of the Occult Academy, it seems that no one else has this qualification, right? ”

"Let's not say a few words, let's take a look at the strength of this instructor first, what if it's very strong?"

"Strong? Hahaha, is our squad leader Ren Tianying strong? Is Instructor Situ strong? No matter how strong he is, how strong can he be? What the hell......"

"That's right, let's see what time it is, I said that I would start teaching at half past eight, it's eight fifty, I'm really convinced, the academy has always been rigorous in doing things, what's wrong this time?"

"Haha, he shouldn't dare to come, right? After all, how many people can teach us, looking at China? ”

As a few people were talking, they saw a gust of wind blowing in the clearing, and the loess was raised, and the trees a few meters away were swaying with the wind, and the leaves collided and made a swishing sound......
