"To practice is to cultivate the mind...... Pressure...... It's actually mental strength......" Thinking of what he said to Zhang Yu just now, Lin Yun sighed slightly and said softly.

In fact, the cultivation method he just told Zhang Yu is still not in-depth, but only superficial.

For example, he taught Zhang Yu how to break through and how to practice, but he did not teach Zhang Yu why he did it.

Combat, pressure, coercion?

Eventually...... Or is it a mental reaction......

There is pressure from the outside world! There is fighting! The spirit will be concentrated, and the mental strength will be concentrated, and this is the fundamental!

Vital...... It's not pressure, it's not fighting, it's concentration!

The former is the cause, the latter the effect!

The most important thing is the effect, but not the cause!

However, he didn't tell Zhang Yu, not that he was hiding his secrets, but that he was afraid that Zhang Yu didn't understand, didn't understand, or ...... It's too deliberate, but it's better to achieve it naturally!

Fighting with people, there is pressure from the outside world...... Mental strength will naturally be concentrated!

However, without these external appearances, you simply want to concentrate...... It's hard! It's hard! It's very hard!

Many things you can do if you don't want to!

There is a gap between imagination and reality!

Soon, the day passed.

In the following days, Lin Yun went to work during the day, cooking, drinking tea, watching the news, pointing out Zhang Yu's cultivation abilities, and occasionally talking to Zhang Yu about things in the north and south, or many things that happened in Cloud City.

In his spare time, Lin Yun will also instruct the chefs of Liuyunju.

Zhang Yu is very grateful to Lin Yun, not to mention, those chefs in Liuyunju are also very grateful to Lin Yun.

In the blink of an eye, more than ten days have passed.

According to Lin Yun's original calculation, after so many days, his ability level could have broken through to C level a long time ago.

However, Lin Yun knew the importance of the foundation, and he had been polishing his abilities during this time, staying at the peak of the E-level realm, and he was not in a hurry to break through.

As the saying goes, there is no limit to cultivation, there is no limit to everything, and in this world, nothing or any realm is truly complete.

F-level, Lin Yun stayed at that level for two years, and also polished his ability for two years, but he didn't dare to say that he had cultivated F-level to the limit and cultivated to perfection.

However, he built a strong foundation for his supernatural powers.

After breaking through to E-rank, Lin Yun only took a little more than two days to raise his ability to the peak of E-rank.

For the next ten days, Lin Yun has been polishing his E-class ability, and in the last two days, he has begun to develop a sense of "limit", which is similar to how he has polished his F-class fire ability to "limit".

This...... That's the importance of the foundation!

Because when he was in the F-class ability, he polished the ability very pure, and now, in just a dozen days, he has polished the E-class ability to the F-level ability for two years.

Lin Yun had a feeling that if he hadn't stayed at F-level for so long and polished his F-level ability so purely, when he broke through to E-level, not to mention the fact that his foundation was unstable, he didn't think he would have reached the current feeling of E-level ability, and he probably wouldn't have reached it in another two or three years.

Sharpen the knife and do not mistakenly chop firewood.

He has laid a firmer foundation, and he can practice faster and farther in the future.

"D-class ......," Lin Yun said softly.

Now, all he needs is one thought, and his ability can break through to D-rank.

"Boom-"

Lin Yun did the same, as soon as his mind moved, the abnormal energy in his entire body suddenly stagnated, and suddenly like a volcanic eruption, it was running rapidly, increasing rapidly, and becoming powerful rapidly...... An even more powerful aura loomed over him.

D-class!

At this moment, his ability level officially broke through to D-rank!

"Senior...... Predecessor...... You ......"

At this moment, outside the door, Zhang Yu first shouted, but did not hear Lin Yun respond, only the next moment, Zhang Yu quickly pushed the door in and saw this scene.

At that moment, Zhang Yu's heart was slightly shocked.

He sensed the powerful fire-based ability on Lin Yun's body, and this aura was far stronger than him, not only in terms of quantity, but also in terms of quality.

And this mass of fire abilities ...... He'd seen it in a fire-type powerhouse stronger than him!

This is...... D-rank fire!

Lin Yun's fire-type ability ...... I actually broke through to the D-class!

Zhang Yu's heart was both shocked and excited.

What shocked was ...... During this time, he vaguely guessed that Lin Yun's ability level should not be recoverable, but ...... Lin Yun wanted to leave Chaopintang, but he deliberately did not recover!

After leaving the Super Grade Hall, Lin Yun's ability level began to recover!

And as far as he knew, Lin Yun had not left the Chaopin Hall for many days...... So far, less than twenty days!

This means that it is very likely that in less than twenty days, Lin Yun's ability level will be restored from F-level to D-level!

That's so fast!

This also means that Lin Yun's ability level can indeed be restored, and at this rate, I'm afraid it won't take long for Lin Yun's ability level to recover to the previous A-level!

And he ...... A little E-class powerhouse actually befriended such a big guy!

How can Zhang Yu not be shocked? How can he not be excited?

However, then, Zhang Yu was shocked in his heart.

Just now, he sensed that Lin Yun's room suddenly erupted with a powerful supernatural power, he was worried that something would happen, so he shouted Lin Yun, Lin Yun didn't respond, so he broke in directly, but he didn't expect to see Lin Yun breaking through the D-level.

That's right, he could see that Lin Yun's fire-based ability was transforming, and obviously, Lin Yun's fire-type ability had just broken through.

This...... Does it count as breaking Lin Yun's secret?

Zhang Yu was a little apprehensive in his heart.

He thought of what Lin Yun had told him earlier to keep it a secret.

This time...... He didn't find out when he broke in without Lin Yun's permission......

"Senior, I'm sorry, I didn't know you were practicing here...... I'll go out now!" Thinking of this, Zhang Yu hurriedly said.

Now, when you turn around, you have to walk towards the door.

"You don't have to leave, now, my ability is changing, you can sense this change, it will be good for you to break through to D-rank......" At this time, Lin Yun opened his eyes and said.

Although, his ability has dropped to E-level, but his ability has changed greatly, plus, he used to be an A-level invincible ability, his sensing power far exceeds that of ordinary people of the same level, usually, Zhang Yu came over at this time, just now, when Zhang Yu walked outside, how did he not sense it?

He chose to break through just now, but in fact, he sensed that Zhang Yu was coming.

On the one hand, since he decided to befriend Zhang Yu, he moderately showed his strong strength and strong potential, which could also make Zhang Yu's heart more inclined to him.

In case, if there is something in the future, it can also make Zhang Yu more inclined to think about things on his side.

On the other hand, it is also what he said at the moment, when he breaks through, his ability will change, and Zhang Yu senses this change, which will be beneficial to Zhang Yu's fire ability to break through to D-rank.

It must be known that his current breakthrough is also the breakthrough from E-level to D-level, which is the same as Zhang Yu's next accurate breakthrough.

This kind of breakthrough change is of great help to Zhang Yu.

Of course, it was also the reason why he recognized Zhang Yu during this period of time.

Otherwise, he and the other party will only have a shallow relationship, and they will not let the other party drink so much tea, let alone show their strength and think about each other or something.

"Huh?" Hearing Lin Yun's words, Zhang Yu's heart moved.

Meditation is a very personal matter...... Realm breakthrough is the top priority in a person's life.

If there is a little disturbance and a little flaw, it may be a lifelong regret.

Therefore, most of their supernatural people break through the realm to find a secret place, and they are not allowed to be disturbed by the outside world.

I didn't expect ...... Lin Yun actually said that......

At this time, after Lin Yun finished speaking, he had already closed his eyes again.

Zhang Yu opened his mouth, but in the end he didn't say anything, he was afraid of disturbing Lin Yun.

After thinking about it, he walked back to Lin Yun's side, carefully sensing the aura of change in the ability that Lin Yun emanated.

"Is this the process of changing from an E-class ability to a D-class ability......" For a moment, Zhang Yu was excited.

At this moment, he sensed a lot of ......

Once, he didn't have a clue, but this moment he also found the signs.

"I see! I see!" Ten minutes later, Zhang Yu was very excited.

Originally, he wasn't sure when he would be able to break through to D-class...... Now, he is almost very sure that in ten days at most, he will be able to break through to the D rank.

His fire-based ability stayed at Tier E for five or six years...... It has stayed at the peak of the E-level for three or four years......

After so many years, it was impossible to break through!

10 days...... This time is almost negligible!

After a few more minutes, Lin Yun opened his eyes.

looked at Zhang Yu with a light smile and asked, "Now, how do you feel?"

More than twenty minutes had passed, and he had already stabilized the D-rank fire ability in his body, and he had increased his cultivation a little.

On the one hand, don't want to be too amazing.

On the other hand, he also wanted to let Zhang Yu feel for a long time, so he extended the breakthrough process as long as possible.

Now, I am very sure that within ten days, I will break through to the D rank!"

Zhang Yu opened his eyes, looked at Lin Yun, and said excitedly.

For those of them who have powers, they are dependent, half of their lives.

Without Lin Yun, he still doesn't know how many years it will take to break through his fire-based ability to D-rank, and even, he can't break through again in this life.

D-rank and E-rank abilities...... These are two big levels! Not to mention one heaven and one earth, it's almost the same!

This grace is no less than that of regenerating parents!

"It's good to have a harvest!" Lin Yun smiled slightly and said.

"Senior, just now, you deliberately broke through the ......" At this moment, Zhang Yu suddenly thought of something and asked.

Just now, he also thought about it a lot, thinking of this possibility......

A breakthrough is not something that can be accomplished in a short period of time.

This place is not a hidden place.

Usually, he also came at this time.

The door is not closed, and outsiders can break in at any time.

He was thinking, perhaps, Lin Yun deliberately broke through and let him sense.

for...... Naturally, it is to help him break through to the D rank as soon as possible!

"Guess?" said Lin Yun with a smile.

"Zhang Yu, thank you seniors!"

didn't say anything more, Zhang Yu just bowed deeply to Lin Yun.

He knew in his heart that there was a chance that this matter would be enough.

Even if Lin Yun didn't deliberately break through here at this time, but at the time of the breakthrough, nine times out of ten he thought of something that would make him sense the change in his ability.

Otherwise, Lin Yun locked the door, it was just a very simple matter.

This gift was not refused, and Lin Yun accepted it calmly.
