Ling An’s right eye is hot, which often means unusual things. But even Ling An has not found the rules.

When in the red fog area, the hot right eye almost indicates an enemy situation. But in this fortress, Ling An believed that even thirteen masters could not sneak in.

On Mars, Ling An vaguely knew that there should be no less than ten S-class warriors. In addition to the five guarding the four fortresses, the rest were necessary to be in the fortress or in the Red Mist Zone.

Of course, the names of these S-class warriors were not something he could know, and at most he would know their titles.

In addition to encountering enemy situations, the right eye sometimes becomes hot. For example, when he advanced to C level, when facing the white-haired man who looked old, Ling An's right eye became slightly hot.

Could this person be an S-class warrior?

Thinking of this, Ling An had the idea of ​​going forward to communicate with the man who was suspected of an S-class soldier. When he reacted, he was surprised to find that he had already walked towards the man.

The handsome man looked about thirty years old, but Ling An knew that it was difficult to accurately judge the age of the engine warrior by his appearance.

Just like the old man Zhou Yang, he is actually over 60 years old, but he looks like he is only in his early fifties and his hair is black.

"Little brother, is there anything wrong?"

Perhaps watching Ling An walk towards him and suddenly stop standing still, the man turned his gaze to Ling An and asked with a smile.

There are not many opportunities to meet an S-class warrior. Ling An thought about it and said:

"This...sir, I saw you looking at the Zhoutian Tower here, and you didn't have a uniform or identity plate on you, so I was a little curious, so I wanted to come and ask, my name is Ling An, I am a member of the Fifth Legion. I don't know what you call me?"

The man looked at Ling An a few times, and did not seem to think Ling An was presumptuous, and said with a smile:

"I just said, your breath is far from level B. It should not be the guard here. It turns out that it is a soldier of the Fifth Legion!"

He stretched out his hand to Ling An affectionately.

"You don't have to be so reserved and respectful. You can call me a red outfit."

Ling An was puzzled, and the name always felt a little strange.

"Hongfu?"

Hongfu seemed to understand Ling An misunderstanding and explained with a smile:

"It's not the flood, it's the red, the outfit."

Red dress... Red, this is a rare surname, and it doesn't look like a man's name. Could it be, it's a title?

Ling An scratched his head and politely held the hand of the red suit.

"Mr. Hong, I feel that your strength is very strong. I wonder what level of warrior you are? Which legion is from?"

Red dress smiled.

"Brother Ling An, in the Glorious Army, I casually inquire about the level and position of the person who did not have the nameplate. However, if you don't do it properly, it will cause some unnecessary misunderstandings."

Ling An smiled awkwardly. Of course he knew that because the higher demons had the ability to learn information from humans, the information of some soldiers was not disclosed, and only those who came into contact with them were clear.

Ling An, who had been read in part by the seventh master, certainly had a deep understanding of this.

"Sorry, I was abrupt." Ling An apologized quickly.

"It's okay, little brother, I haven't been to the front line for a long time. When I saw you energetic little guys, I remembered when I was young..." Hongying suddenly looked melancholy.

Ling An immediately felt awe-inspiring. He had contact with General Zhou Yang, General Milton, and Commander Lin Cheng's army, and felt a similar temperament in the red suit.

This one, at least, is quasi-S-level and has not run away!

I just felt it carefully, but I was a little bit short of it. Have I been injured?

"Little brother, look at your body. It seems that you have used secret techniques to cause interstitial weakness. What? Have you just returned from the Red Mist Zone?"

Ling An was naturally happy when he was willing to talk to him in the red suit.

Among the strong men above level A who has ever seen, the red suit looks the youngest. This kind of engine warrior who is both a genius and a strong man is the senior on Ling An's path of cultivation.

"Well, it's very miserable, this time..."

Ling An and Hongzhuang said while walking, and before they knew it, they walked outside a cafe and simply sat down.

In addition to the content that cannot be said, Ling An seemed to be confiding, telling Hongying about the experience in the Red Fog Zone. This man felt trustworthy, which was something that President Zhou Yang could not bring.

"It looks like this, it's really not easy for you to come back alive." After hearing this, Hongfu sighed.

The soldiers sitting around seemed to turn a blind eye to this guy in a black tuxedo. He tapped the table with his slender index finger with his right hand, looking very sad.

"That's right, but wars must be fought. Once Mars is broken through, the earth will be threatened and humans will face a crisis. Even if they lose or are injured, they must continue to fight until one day the alien races are wiped out to maintain peace on the earth."

The alien race is bloodthirsty, but the most important thing is that the demon needs to devour human life to restore its strength.

The strength of the seventh master made Ling An know how terrible it would be once the demons recovered their full strength. If they broke through Mars, humans would have no chance of winning, unless they could build another Zhoutian Tower and create another Zhoutian curtain at that time.

Hongfu suddenly stood up and walked into the cafe. Soon, he brought out twice the coffee.

He handed a cup to Ling An, and then asked:

"Ling An, what do you think is the difference between alien races and humans? Or, more precisely, what is the difference between demons and human engine warriors."

Ling An was stunned. The difference between the demon and the engine warrior? What is the point of considering this?

"Think about it carefully, as the demons of the alien ruler clan, they also have many similarities with humans. They have their own personality differences, they can intrigue and even know how to use human hearts better than humans..."

Ling An looked at Hong's clothing in surprise. This was the first time he had heard these remarks.

But if you think about it carefully, the demons and humans are really similar in some aspects. Of course, Ling An would never think that the two have any origins, because these can be attributed to the unified result of the development of intelligent life.

"But there is a big difference between us and demons." The red suit was still telling the similarities between humans and demons, and Ling An couldn't help but say.

Hongfu was stunned for a moment, then laughed.

"Yes, of course the difference is very big. For example, the growth of the demon's strength is natural, and it is almost impossible to encounter obstacles if it does not reach a certain level. It is just a matter of time. But humans are different. Even if they rely on the engine, they need strong three-sense stimulation to promote their own progress. The accumulation of time seems less important. This should be the difference between the limiter."

"Limiter?" Ling An was interested.

He felt that the red outfit was really interesting. He was even more like a scholar who had a deep interest in various strange knowledge than an unfathomable warrior.

"Why, I'm interested in the limiter. Brother, I still have some time. If you have this leisure, I'll tell you slowly."

"Okay." Anyway, there was nothing else going on in the morning, and Ling An was so happy to listen to Hongfu's talk.

The red suit seemed to be happy for someone to listen to his speech, and started talking nonstop again.

The so-called limiter is actually a probability that humans have long proposed.

Due to the various differences between species and individuals, there are limits for the original substance that constitutes the individual species. Therefore, each individual has a limit that cannot be eliminated no matter how much effort it takes.

Ants can carry objects hundreds of times heavier than themselves, but cannot move a person. It also has its limits.

It is like God creating species while installing a lock on all living beings, allowing them to survive in normal and orderly rules.

However, the limiters of demons and humans are a little different.

Red suit said that the devil's limiter is very high, surpassing all other creatures of the alien race, so they can become the rulers of the alien race and reach the strength of the Demon Lord or even the Demon Lord. If the Skywall had not suppressed the demons, humans would not be their opponents at all.

But human restrictors are very strange.

The engine allows humans to break through the upper limit that was originally considered impossible to break through. Humans will never survive extreme oxygen, and they will even be unable to compete with tigers, lions and other wild beasts with empty hands. With the engine, human individuals themselves can continue to break through.

"So, after the engine is implanted, is human still human..." Hongqi sighed.

According to his idea, this is artificially transforming humans into another species, changing the size range of the limiter.

Ling An took a sip of coffee and a bold idea popped up in his mind.

"Mr. Hong, the limiter is indeed reasonable, but... is it possible that humans themselves have such a high limiter? There is a possibility of being on the image, and even the S-class is not the end point of the engine warrior?"

Ling An said this, not completely unfounded, because in fact, if you think about it carefully, the engine is more like a power bank, which can absorb energy that humans could not absorb before and provide it to humans. Isn’t it still relying on the humans themselves to make a real breakthrough?

He was stunned for a moment in red, and his smile slowly disappeared.

Ling An thought he was angry and quickly apologized.

"Mr. Hong, I'm talking nonsense, don't mind."

The red outfit has such a friendly attitude, and Ling An didn't want to lose the opportunity to be friends with someone who is mostly an S-class warrior.

"It's okay, you're not talking nonsense." Hongbao smiled and looked up at Zhoutian Tower.

"It's getting late, I still have something to do, so I have to leave."

Hongfu got up, waved at Ling An, and walked towards Zhoutian Tower himself.

He is indeed a big shot when he can enter the Zhoutian Tower. But Mr. Hong is really interesting.

Ling An finished two or three sips of coffee, and when he said the limiter, it actually had no practical significance to him.

Because no matter whether there is a limiter or not, the way he wants to go is still far away and can't see the end.

The figure in red dress disappeared at the end of the street.

He was very fast, and he was walking leisurely, and for no reason he crossed a long distance.

Walking into the Zhoutian Tower, the guards at the door did not even check his ID.

With his hands behind his back, Hongsuit rushed through the inside of Zhoutian Tower. He met several people on the way, all of whom were emitting A-level aura, but they all turned a blind eye to Redsuit.

Hongzhuang walked up the ring-shaped staircase inside the Zhoutian Tower and soon stepped into the top floor of the Zhoutian Tower.

Here is the end of the stairs, with only a small door.

"Come in, come in." The old voice came from it. The red costume smiled slightly, and there was no movement, and the door opened automatically.

Behind the door is a small room, with only a bed, a rocking chair, a desk, a tea cabinet, and a bookshelf filled with books.

An old man with white hair and beard and dressed in a retro Zhongshan suit, lying on a rocking chair with his eyes closed.

The room was extremely quiet, with only the slight creaking sound of the rocking chair shaking. There were a few photos hanging on the wall, with the characters on it including men and women.

"You have seen him, what have you said?" The old man suddenly opened his mouth, but still closed his eyes.

"Don't you hear what I said to that kid?" Hongbao smiled. "The little guy you chose is very interesting. Don't worry, I'm just talking to him. I won't mention anything he shouldn't have come into contact with now."

The old man nodded softly and stopped talking.

Hongbao didn't say anything, looked at the room a few times, then turned around and left, as if he had come here just to look at the old man.

The door was gently closed, and the old man's eyes opened a small gap. It was obvious that there was no wind, but the books on the desk were opened by themselves.
Chapter completed!
