"What's wrong with this, you use your ability, I'll see!" Lin Yun said with a smile.

In the last two years of his super product hall, he taught the newcomers of super product hall, and he taught a total of two or three hundred, how could he be Zhang Yu?

"Okay, I'll use it and let the seniors take a look!" Zhang Yu's eyes lit up, and he nodded continuously, he didn't expect that Lin Yun would agree to this matter so easily, which made him feel excited.

His fire-based ability has been in the E-rank for many years, and it can be said that he wants to break through in his dreams, but today, he sees two hopes in succession, so how can he not be excited?

"Boom!"

As he spoke, Zhang Yu had already used his fire ability, and immediately, a fire dragon appeared out of thin air, quickly wandering around this room, and the temperature of this room immediately began to heat up rapidly, but under Zhang Yu's control, the temperature of this room quickly dropped again.

The fire dragon leaped, vividly, and even opened its mouth, and a faint "beast roar" occurred.

This process lasted for about tens of seconds, and Lin Yun waved his hand to let Zhang Yu put away the fire ability.

"Your fire-based abilities are too loose, and your impact on the D-level realm should be mainly based on increasing the number of abilities, right?"

"Yes, it's not that quantitative changes cause qualitative changes, I want to increase the number ......of abilities as much as possible, so as to cause qualitative changes," Zhang Yu said with a red face, listening to Lin Yun's meaning, it was obvious that he was doing something wrong.

"Quantitative change causes qualitative change, this sentence is not wrong, but there are two conditions, one is that the quantity reaches an extremely high level, but this condition is not so easy to achieve, because if a person's body does not undergo qualitative change, the number of abilities it can bear is also limited, unless some people's talent is excellent, which involves the problem of talent. Lin Yun shook his head and said.

"What about the second condition?" Zhang Yu said with a wry smile, after all these years of ability cultivation experience, he thought that his talent was just average.

"The second condition is the assistance of external pressure, as the so-called, thousands of tempers into steel, when the quantity reaches a certain level, and then assisted by external pressure, it can be impacted to a higher realm. Lin Yun said slowly.

"The assistance of external pressure?" Zhang Yu was shocked in his heart.

As the saying goes, if you falsely pass on ten thousand scrolls, you can really spread a word.

Lin Yun's words gave him a feeling of enlightenment, and made him vaguely find his direction.

"How can you get this external pressure ......" Zhang Yu scratched his cheeks, eager to know the answer.

"You don't use your ability often, do you?" said Lin Yun with a smile.

"This ...... After the ability is used, it is not easy to replenish it, and I am afraid that I will encounter unexpected situations at any time......" Zhang Yu said embarrassedly, he was not stupid, Lin Yun's words made him vaguely know where the problem was.

"Many things pay attention to the balance of yin and yang, yin and yang complement each other, there is a saying in the practice, called internal and external sense, I don't know if you have heard of it? Another example, some chemical reactions, the collision of two substances...... The oxidation reaction of the human body and so on......," Lin Yun said.

Zhang Yu listened a little big.

How does this have to do with the way of yin and yang, chemical reactions, and oxidation reactions in the human body?

"Look at this water, it's in this bottle, and as long as the cap doesn't open, after a long time, it's still clean water...... However, once the cap of the bottle is opened, it will gradually deteriorate when it comes into contact with the outside substance, why? Because the water in the bottle reacts with the outside substance!" Lin Yun smiled, pointed to a bottle of mineral water on the table, and said.

"This ......" Zhang Yu was still puzzled.

"Your ability has been staying in the body, not often in contact with external substances, although it keeps some aspects relatively clean, but it also lacks certain substances, for example, thousands of tempers to become steel, but also because iron absorbs some things from the outside world, it becomes steel, naturally, the ability must also be used frequently, contact with external substances, fusion of external substances, in order to occur quality improvement...... Lin Yun said.

"That's so? Not bad, not bad! Tempered into steel! Tempered into steel! Tempered into steel! Internal and external sense! I understand! I understand!" Zhang Yu shook his body and said very excitedly.

This time, Lin Yun told it more clearly, Lin Yun gave many examples to illustrate this matter, some examples he didn't understand at first, but he knew some examples, and then through the front and back, he suddenly had a feeling of enlightenment.

"This is just the first step!" Seeing that Zhang Yu understood, Lin Yun shook his head with a smile.

"Huh?" Zhang Yu was a little dumbfounded.

"Pressure! Naturally, it's not just the internal and external contact reactions, it's called pressure!" Lin Yun shook his head.

"However, didn't you just say that it is ...... tempered by a thousand tempers," Zhang Yu said dumbly.

"Hehe, you also said that you have been tempered a lot...... You don't have a deep understanding of this sentence, iron comes into contact with external substances, and various reactions occur before the quality changes, however, how does iron react with external substances? Is it just a matter of simply putting it there? Naturally not! It needs to be tempered a thousand times! First, it needs fire! Second, it needs to be hammered! Therefore, this step is actually divided into two small steps!" Lin Yun said.

"Fire ...... Hammering ...... Senior, can you elaborate a little more......" Zhang Yu thought about it, and finally smiled bitterly.

In fact, he is many years older than Lin Yun, but the cultivation of this thing is really not just a matter of age, it is really the master who is the teacher, although Lin Yun is young, he once had extremely high achievements, and a casual sentence can make him gain too much.

"If you use the ability a lot and regenerate it, you can gradually increase the quality of the ability, but it's too slow, and it doesn't necessarily make the ability break through the limit, and if you want to improve quickly and break through the limit, you need real pressure......! Fighting! In battle, people's mental power will be highly concentrated! Mental power is mental power, mental power is ability control, it is the hammer, the more times, the quality of the ability will gradually improve!"

"Or, bear a certain amount of coercion, etc.!Chaopintang has a kind of coercion room, I don't know if you have used it, it has the effect of this external pressure!"

Lin Yun smiled slightly and said.

The coercion room, Chaopintang has this kind of equipment, but the number is very rare, and only a very few people can use it.

There is a lot of merit and good talent, and it is generally the two selection criteria for the use of such equipment.

In the past, Lin Yun had used it many times, and the fact that he could break through to the A-level realm so quickly also had a lot to do with the fact that he had used this kind of equipment many times.

It was precisely because he had used this kind of equipment many times that he understood how difficult it was for ordinary Chaopintang law enforcement to use this kind of equipment.

It's not that he underestimates Zhang Yu, at such an age, the ability level is only E-level, Zhang Yu's ability is not just breaking through, nine times out of ten, the talent is very ordinary, if Zhang Yu doesn't have a big credit, then the possibility of using the supergrade hall's coercive equipment is very low.

"Chaopintang's coercion room?" Zhang Yu smacked.

He had heard of this kind of equipment, but he had only heard of it, and he had never used it, because it took a lot of effort to use this kind of equipment, and at the same time, the talent also needed to be very high, and he couldn't meet the same conditions.

However, it turned out that he had heard that the pressure chamber of the Chaopintang could help a person's ability to break through, but he didn't know what the principle was, and now, he understood.

"Coercion room, I'm not qualified to use it, so only the battle remains?" Zhang Yu shook his head with a wry smile.

Fighting?

In ordinary battles, he estimated that the pressure effect was limited! But if he really fought, maybe it would be dangerous! Fight again and again...... I don't know when I will be able to break through, maybe I will plant a big one one at a time!

Not easy!

It's really not easy!

But...... After listening to what Lin Yun said, he finally knew where to work hard! No longer like the original, he has not been able to break through, there is no progress, and he doesn't know where the problem is!

"Real battles are not easy to encounter, and it is difficult to meet the right ones, but you understand this truth, in the future, your ability will be used often, don't be reluctant to use it, learn more from others, your ability level has reached the peak of E-level, and there is no problem in breaking through to D-level. Lin Yun shook his head and said.

"I understand, thank you seniors for your advice!" Zhang Yu said gratefully.

As the saying goes, listening to your words is better than reading a book for ten years.

He listened to Lin Yun's instructions, and it really had this effect.

What Lin Yun pointed out was not only the matter of his ability breaking through from E-level to D-level, but a majestic avenue, even if he broke through to D-level, he could also practice in the direction that Lin Yun pointed out, and he could also pass on his experience to his friends, and even ...... Future loved ones.

So, the meaning is really huge.

Then, Zhang Yu told Lin Yun some things about Yuncheng and Chaopintang, as long as it wasn't for Chaopintang's strict requirements for confidentiality, it could be said that they knew everything and said everything.

During this period, Zhang Yu also used some fire-based ability moves for Lin Yun to guide.

Lin Yun's guidance again also benefited Zhang Yu a lot.

An hour or two later, Zhang Yu left.

Looking at the direction Zhang Yu left, Lin Yun was thoughtful.

In Chaopintang, he is not a person who only buries his head in penance.

He has carried out a total of hundreds of missions in Chaopintang, and among them, naturally not all of them are battles.

Many tasks are important in terms of time, place, and people.

Naturally, he is also involved.

Now, he has retired and returned to Cloud City.

But the world is about to change.

He couldn't help but plan ahead.

Zhang Yu is not only the deputy director of the Law Enforcement Department of Yuncheng, but also a person from Chaopintang.

The Law Enforcement Division of One City is almost the law enforcement machine of One City.

Chaopintang is also the top law enforcement department in the Great Xia Kingdom.

It can be said that Zhang Yu occupies a very critical position.

At least, that's the case for him at the moment.

Yesterday, he asked a friend from Chaopintang to check on Zhang Yu, and this morning, that friend sent a message, indicating that Zhang Yu is not bad overall and can make friends.

So, there is what happened just now.

Otherwise, although there is an explanation from his parents, Lin Yun also intends to return the favor to the other party, but he will not treat the other party like this, at most, let the other party drink a few cups of tea he made, it will be fine.

Zhang Yu, although he was only an E-level ability, Lin Yun did not look down on the other party.

As he once said, every supernatural person is the pride of heaven in this world, although the other party is far inferior to him, the former A-level invincible powerhouse, the Huoyun Evil God of the Great Xia Kingdom Super Rank Hall, but he is also extraordinary.

Now, he has retired from Chaopintang, and on the surface he is seriously injured, and his ability is not much stronger than a lowest-level F-level ability, but Zhang Yu is an active eight-rank law enforcement officer in Chaopintang, and in many aspects of information, he is really not as good as Zhang Yu.
