Ling An's right eye was hot, which often meant something unusual. But even Ling An didn't find a pattern.

When in the Red Mist Zone, a hot right eye is almost a sign of hostility. But in this fortress, Ling An believed that even the Thirteen Venerables would not be able to infiltrate.

On Mars, Ling An vaguely knew that there should be no less than ten S-class warriors, except for the five who guarded the fortress of the four directions, the rest must be either in the fortress or in the Red Mist Zone.

Of course, the names of these S-class fighters are not something he can know, and he only knows their titles at most.

In addition to encountering enemies, his right eye sometimes gets hot, such as that time, when he was promoted to the C level, Ling An's right eye was slightly hot in the face of the white-haired man who looked drooping and old.

Could it be that this person is an S-class warrior?

Thinking like this, Ling An had the idea of stepping forward to communicate with the man who was suspected to be an S-class fighter, and when he reacted, he was surprised to find that he had already walked towards the man.

The handsome man looked to be in his thirties, but Ling An knew that the age of the engine warrior was difficult to accurately judge by his appearance.

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

"Little brother, is there something wrong?"

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

There are not many opportunities to get acquainted with an S-class warrior, Ling An thought about it and said:

"This ...... Sir, I see that you are looking at Zhou Tianta here, and you don't have a uniform and identity nameplate on your body, so I am a little curious, so I want to come over and ask, my name is Ling An, I am a member of the Fifth Legion, I don't know what you call it? ”

The man looked at Ling An a few times, and didn't seem to think that Ling An was presumptuous, and said with a smile:

"I'll just say, your breath is far from B-level, it shouldn't be the guard here, it turns out to be a soldier of the Fifth Legion!"

He cordially extended his hand to Ling An.

"You don't have to be so restrained and respectful, you can call me red."

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

"Floods?"

The red suit seemed to understand Ling An's misunderstanding, and explained with a smile:

"It's not the flood of the flood, it's the red of the red, the costume of the garment."

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

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

"Mr. Hong, I feel that your strength is very strong, I don't know what level of warrior you are? Which legion is it? ”

The red suit smiled.

"Little Brother Ling An, in the Glorious Army, casually asking about the rank and position of those who have not hung the nameplate is not a very polite thing, and if you don't get it right, it will cause some unnecessary misunderstandings."

Ling An smiled awkwardly, of course he knew that because the high-level demons had the ability to learn information from humans, the information of some warriors was not public, and only those who came into contact with it knew it.

Ling An, who had been read part of his memory by the Seventh Venerable, of course had a deep understanding of this.

"I'm sorry, I was abrupt." Ling An hurriedly apologized.

"It's okay, little brother, I haven't been to the front line for a long time, and when I see you energetic little guys, I think of when I was young......" The red suit suddenly looked melancholy.

Ling An was immediately in awe, he who had been in contact with Commander Zhou Yang, Commander Milton, and Captain Lin Cheng, felt a similar temperament on the body of the red suit.

This one, at least the quasi-S-level, didn't run!

It's just that I feel it carefully, but something is missing, have you ever been injured?

"Little brother, looking at your body, it seems that you used a secret method to cause the interstitial weakness, what's wrong? Just got back from the Red Mist Zone? ”

The red suit was willing to talk to him, and Ling An was naturally happy.

Among the powerhouses above the A-level level he had seen, the red suit looked like the youngest, this kind of engine warrior who was both a genius and a powerhouse, was the predecessor on Ling An's cultivation path.

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

Ling An and the red suit said as they walked, and unconsciously walked to the outside of a café, and simply sat down.

In addition to what he couldn't say, Ling An seemed to confide in the red mist area, telling the red suit about his experience, this man had a feeling of trust, which Zhou Yang had not been able to bring.

"Looking at it this way, it's really not easy for you to come back alive." After listening to this, the red suit sighed.

The warriors who sat around seemed to be oblivious to the guy in a black tuxedo, and the slender index finger of his right hand tapped the table with a very sad look.

"That being said, but the battle can't be fought, once Mars is broken through, the earth will be threatened, and mankind will face a crisis, even if it loses and is injured, it must continue to fight, until one day the alien race is wiped out, so as to keep the peace of the earth."

Aliens are murderous, but most importantly, demons need to devour human lives to regain their strength.

The strength of the Seventh Venerable let Ling An know how terrible it would be for the demons to regain their full strength, and let them break through Mars, and the human race would have no chance of winning, unless at that time, they could build another Zhou Tian Pagoda and create another Zhou Tian Tianmu.

The red suit suddenly stood up and walked into the café, and soon, twice as much coffee was served.

Handed a cup to Ling An, the red suit asked:

"Ling An, what do you think is the difference between aliens and humans? Or to put it a little more finely, what is the difference between a demon and a human engine warrior. ”

Ling An was stunned, the difference between a demon and an engine warrior? What's the point of thinking about this?

"If you think about it, the demons who are the rulers of the alien race also have many similarities with humans, they have their own personality differences, they can intrigue, and they even know how to use people's hearts better than humans......

Ling An looked at the red suit with some surprise, this was the first time he had heard these words.

But if you think about it carefully, demons and humans are really similar in some ways, of course, Ling An definitely doesn't think that the two have any origin, because these can all be attributed to the unified results in the development of intelligent life.

"But we're also very different from the demons." The red suit was still talking about the similarities between humans and demons, and Ling An couldn't help but say.

The red suit was stunned for a moment, and then laughed.

"Yes, of course there is a big difference. For example, it is natural for a demon's strength to grow, and it is only a matter of time before he encounters obstacles if he does not reach a certain level. But human beings are different, even if they rely on the engine, they need a strong three-sense stimulation to promote their own progress, and the accumulation of time is not so important. That's probably the difference between the limiters. ”

"Limiter?" Ling An was interested.

He found it more and more interesting to be in red suits. Even more like a scholar with a deep interest in all kinds of strange knowledge than an unfathomable warrior.

"Why, I'm interested in the limiter, little brother, I still have some time, if you have this leisure, I'll tell you about it slowly."

"Okay." Anyway, there was nothing else to do in the morning, and Ling An was happy to listen to the red suit.

The red suit seemed pleased that someone was listening to him, and began to talk again.

The so-called limiter, in fact, human beings have long been probable about this.

Due to the differences between species and individuals, there is a limit to the original substance that makes up the individual species, so each individual has a limit that cannot be eliminated no matter how much effort is put in.

An ant can lift an object that is hundreds of times heavier than itself, but it cannot move a person, and it has a limit.

It's like God created species at the same time, and put a lock on all creatures, so that each species can survive in normal and orderly rules.

However, demons are a bit different from human limiters.

The red suit said that the demon's restraint device is very high, surpassing all other creatures of the alien race, so they can become the ruler of the alien race, reaching the strength of the demon lord or even the demon lord, if it weren't for the suppression of the demon by the canopy, the human race would not be their opponent at all.

But human limiters are weird.

Engines allow humans to break through limits that were initially thought to be impenetrable, and humans will never survive in extreme oxygen deprivation, or even fight against beasts such as tigers and lions empty-handed, but with engines, individual humans themselves can continue to break through.

"So, after the engine is implanted, are humans still human......" sighed in the red suit.

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

Ling An took a sip of coffee, and a bold idea popped into his head.

"Mr. Red, the restrictor does make sense, but ...... Is it possible that humans themselves have such a high limiter? In itself, there is a possibility that even the S-class is not the end 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 can't absorb before and supply it to humans.

The red suit was stunned for a moment, and the smile slowly disappeared.

Ling An thought he was angry and hurriedly apologized.

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

With such a friendly attitude, Ling An didn't want to lose the opportunity to be friends with someone who was mostly an S-class fighter.

"It's okay, you're not talking nonsense." The red suit smiled and looked up at Zhou Tian Tower.

"It's not too early, I still have something to do, I have to go."

The red suit got up, waved his hand at Ling An, and walked towards Zhou Tian Pagoda by himself.

can enter the Zhou Tian Tower, and it is really a big shot. But Mr. Red is really funny.

Ling An finished two or three sips of coffee, and said that the limiter actually had no practical meaning to him.

Because with or without a limiter, the road he has to go is far from end.

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

His speed was very fast, obviously he was walking leisurely, and he somehow crossed a long distance.

Walking into the Zhou Tian Tower, the guards at the door didn't even check his documents.

With his hands behind his back, the red suit shuttled rapidly inside the Zhou Tian Tower, and met a few scattered people on the way, all of whom exuded an A-level atmosphere, but they all ignored the red suit.

The red suit walked up the circular staircase inside the Zhou Tian Tower, and soon stepped into the top floor of the Zhou Tian Tower.

This is the end of the stairs with only a small door.

"Come on, come in." The old man's voice came from it, and the red suit smiled slightly, but there was no movement, and the door opened automatically.

Behind the door was a small room, with only a bed, a rocking chair, a desk, a tea cabinet, and a bookshelf full of books.

An old man with a white beard and a retro tunic lying in a rocking chair with his eyes closed.

The room was extremely quiet, save for the subtle creaking of the rocking chair as it swayed. There are several photographs on the walls, showing men and women.

"You've already met him, what did he say?" The old man suddenly opened his mouth, but his eyes were still closed.

"Can't you hear what I said to that kid?" The red suit smiled. "The little guy you chose is very interesting, don't worry, I'm just talking to him, I won't mention anything that shouldn't be in contact with him now."

The old man hummed softly, and then stopped talking.

The red suit didn't speak, looked at the room a few times, and then turned to leave, as if he had come here just to see the old man.

The door closed gently, and the old man's eyes opened a small slit slightly, obviously there was no wind, but the books on the desk opened by themselves.

"If only you could do what you say......"
