Lin Yu's first class of ability cultivation was also the third class of this substitute teacher and five other students.

From Shi Xing's lecture style, Lin Yu could see that this person has a lot of teaching experience.

According to what he said during his nagging, he had previously served as an ability cultivation instructor for new recruits in the Guardians of Earth base.

He is also the only one with rich teaching experience among the 14 substitute teachers in the Abilities Cultivation College of S Normal University.

According to him, his current strength is at the peak of the first level, and while he is guiding the students to cultivate, he will also cultivate himself.

His duty this time is to bring these six elite-level students to the second level, and at that time, his mission will be completed, and there will be the next batch of substitute teachers to lead them in the follow-up course learning.

At that time, there will definitely be a breakthrough in his strength, and he may be able to reach the peak of the second level.

Of course, looking at Lin Yu's speed of progress.

At the beginning of the class, Shi Xing first took everyone to carefully review last night's class.

Why do you have to review it carefully, of course, to take care of this new classmate who has just arrived - Lin Yu.

Lin Yu was also listening carefully to the review, trying to record it word for word, so that it would be easy to tell others when the time came.

Fortunately, with Lin Yu's current memory, this is not a difficult matter.

In fact, there wasn't much content about cultivation that I really learned last night, and to be precise, there wasn't much content that applied to Gu Wen.

Because now, except for the Abnormal Ability Cultivation Academy and the base of the Earth Guardians, there are no cultivation altars in other places.

However, Lin Yu believes that it won't be long before this kind of altar will be imitated.

In last night's class, Teacher Shi Xing mainly explained the history of the core of Reiki, of course, it is history, but it is actually a matter of the past few years.

Shi Xing joined the Earth Guardians in the early days, and at that time, the Earth Guardians had not restricted the conditions for joining the Earth Guardians.

Basically, anyone can join, but Ma Zhen and a few elders will regularly purge some disloyal team members.

It wasn't until the number of Earth Guardians reached a certain level that the conditions for joining began to be slowly restricted.

It is said that this restriction was proposed by Cang Ling, the beautiful military master of the Earth Guardians, and it is because of this condition that the overall quality of the Earth Guardians has risen several steps.

Due to the search for excellent candidates from among college graduates, young college students have active minds and strong physical plasticity, so there are many rising stars who are more capable than those who joined the Earth Guardians in the early days.

Then Teacher Shi Xing explained the use of the cultivation altar, which included cultivation with and without aura core.

In other words, as long as you have a cultivation altar, even if you don't have an aura core, you can still cultivate.

Now in the heaven and earth, the aura has gradually become stronger.

In fact, just by lying on the bed and sleeping, you are already cultivating.

It's just that if you master a certain means of absorbing the aura between heaven and earth, the speed of cultivation will go up a higher level.

If you are through the bonus of the cultivation altar, then the speed of absorbing spiritual energy will be even higher.

Add another aura core, it is equivalent to hanging up, because the current aura between heaven and earth is far less rich than the aura core.

Lin Yu sat on the cultivation altar, feeling the experience of class that he had never had before.

Sima Lezhang sat in front of Lin Yu on the left, in the center of the first row of the classroom.

When Lin Yu looked at Teacher Shi Xing, he would inevitably notice him.

And Sima Lezhang has indeed been listening to Teacher Shi Xing's lectures seriously, and what's more, he also takes notes from time to time.

When Lin Yu saw this scene, he sneered a little in his heart, after all, he had already memorized what Teacher Shi Xing said.

It seems that memory is a bonus from the bloodline of the divine beast, and these ordinary awakened people, their memory is still no different from when they were not awakened.

Next, Shi Xing talked about some details of the use of the cultivation altar, and let everyone start cultivating by themselves.

At the beginning of his cultivation, Lin Yu noticed that among the other students, only Sima Lezhang's cultivation altar had an aura core embedded in the aura, but this aura core had no light.

This thought that the aura in this aura core had been absorbed by Sima Lezhang.

"No wonder when I saw Sima Lezhang at noon, he ate in such a hurry, and ran out of the restaurant after eating."

While thinking in his heart, Lin Yu began to recall the details of the cultivation that Teacher Shi Xing had said, and began to cultivate on the cultivation altar.

Before cultivating, Lin Yu didn't know if absorbing aura would have any effect on his alien.

However, when he sat cross-legged on the altar of cultivation and began to connect with the altar in a meditative way.

He felt a movement in his left palm.

"It's Sei-kin! How could it be so excited about Reiki? ”

Lin Yu was shocked in his heart, although he didn't have an aura core, he didn't absorb much aura in cultivation, but this was also stronger than sleeping.

And this is the result of a room full of 7 people cultivating together.

That's right, Teacher Shi Xing is also cultivating in this classroom, his cultivation method is different from others, his cultivation altar is much smaller, it seems to be a portable altar that can be carried around, this is a good thing.

It's just that Teacher Shi Xing also cultivated by not having an aura core, because he was only an awakened person with a first-level peak strength, and the Earth Guardians only issued him three aura cores every month, and he had already used it in his cultivation.

Lin Yu was still in the dark now, he thought that all members of the Earth Guardian Team received the same number of Aura Cores every month, but in fact, there were strict regulations on the number of Aura Cores distributed by the Earth Guardians.

Two per month for the entry level, three per month for the first level, and in turn.

Chengying's abnormal movement made Lin Yu happy in his heart, which meant that his cultivation would not be in vain.

The next thing is to see what benefits the Chengying Sword will gain from the absorption of aura.

As soon as he thought of the Chengying Sword, Lin Yu suddenly remembered Zhang Dao, the lonely master, and his heart was suddenly full of guilt.

Anyway, when I go back tonight, I will go to the world inside the giant tree to visit Master Zhang Dao.

The cultivation of less than two classes ended quickly, and Lin Yu felt the changes in Chengying at all times while cultivating.

But to his disappointment, after a night of cultivation, Chengying did not change at all, but kept moving excitedly, which made Lin Yu's left palm very uncomfortable.

If it weren't for Chengying being Lin Yu's big killer, Lin Yu would have the heart to lose it.

At the end of the second class, Teacher Shi Xing announced another thing before the end of the class.

That is, every month in the future, the Earth Guardians will provide an aura core to the students who sign up to improve the strength of the students.

The aura core doesn't need money now, but it will be recorded in the student's file, and in the future, the student will need to return the aura core to the Earth Guardians, or return other things of equal value.

This is equivalent to saying that the Earth Guardians first let the students overdraft their aura core, and when they have the strength in the future, it will be relatively simple.

And the Earth Guardians didn't say anything about the interest.

"This is simply the conscience of the Earth Guardians!" Lin Yu thought to himself.

However, at the end of Teacher Shi Xing's speech, he also specially reminded that there is still a time limit for the return of the aura core, and it must be paid off within two years after the end of the course.

As for the situation that can't be paid off, Teacher Shi Xing didn't say that according to Lin Yu's guess, this won't be much better.

"Okay, now I announce the official explanation of today's lesson, if you want to continue cultivating, you can also use the cultivation altar here until ten o'clock tonight, because the academy building will be closed at ten o'clock." Teacher Shi Xing said as he packed up a few printed A4 sheets of paper he had brought and walked out of the classroom.

Lin Yu originally planned to go back to the dormitory directly, but he didn't expect that after Teacher Shi Xing finished speaking and walked out of the classroom, they resettled and began to cultivate.

"You're too diligent, aren't you?" Lin Yu complained in his heart.

However, this phenomenon is also reasonable, after all, for the current awakened people, the use time of the cultivation altar is precious.

Fortunately, the Earth Guardians do not limit the use time of the cultivation altar at all, as long as it is the normal opening time of the teaching building, the cultivation altar will be open to students.

Moreover, the Ability Cultivation Building closes even half an hour later than the other academy buildings.

The other college buildings were completely closed by half-past nine in the evening.

In this way, Lin Yu cultivated for another hour.

At this time, the voice of the building manager who wanted to clear people had already come from the corridor.

Only then did the six students of Class 14 get out of their cultivation state and began to pack up their things and prepare to go back to the dormitory.

Since Lin Yu and Sima Lezhang didn't bring anything, they were refreshed and didn't need to rest at all.

Just as Lin Yu and the other four people waved goodbye, Sima Lezhang had already left the classroom in a hurry.

It just so happened that Lin Yu didn't want to go with him, after all, the two of them were still in the same dormitory building, and if they walked together, they would inevitably come together, which Lin Yu couldn't bear.

In this way, Lin Yu rubbed in the classroom with a few other classmates for a while, and left the Ability Cultivation Building with them.

"Hey, Lin Yu, why don't you go with Sima Lezhang? Aren't you from a dormitory? Just drop by. Xiao Qing said, with a hint of teasing in her eyes.

Lin Yu knew that she also knew Sima Lezhang's character, so it was just Xiao Qing joking with him.

"Miss Xiao, don't laugh, I'm a little person in Lin Yu, how can I be worthy of going with someone like Sima Lezhang!"
