In professional circles, there is a well-established saying, or it can also be said to be an axiom, that both the earth and the home world agree on one point: the cross-level battle of a professional cannot exceed the third level in any case.

This is known as the "three-level boundary".

To put it simply, even if the two sides of the battle, one side is a super life, holds an artifact, has super top abilities, and is extremely talented, while the other side is the weakest professional, defenseless, and his ability is even more half-witted, and he is completely a weak chicken. But as long as the level of the former is more than three levels worse than the latter, it is a loss, and it is useless to have any professional advantages, racial advantages, weapon advantages, and ability advantages.

It's a bit like the concept of "level suppression" in some e-sports games on the planet, once the level difference is too large, it is useless to buy any equipment and show any operations.

Li Xiaosen is currently a first-level professional, and according to the theory of "third-level boundary", the limit of his challenge should be a fourth-level professional.

But even battle mages have a hard time approaching this boundary.

The reality of being really in the professional world is:

To be able to take on a challenge is a great thing.

If you can surpass the two levels, it is already a rare existence, and the earth ability circle is probably only the ten people on the heavenly list who have this ability.

As for the third-level challenge, even in Li Xiaosen's home world, it is theoretically possible, and no one knows whether it exists in reality or not, anyway, Li Xiaosen has never heard of it in his previous life.

Li Xiaosen's previous opponents who crossed the ranks—the projection clone of the Minister of Adjudication, Yan Zong, Ge, and Rose who ate the Soldier Ability Pill—actually did not go beyond the scope of the third-level boundary, in other words, theoretically possible.

It is true that none of these opponents pose a real threat to his life. Even if the projection clone of the Minister of Adjudication is not as strong as her own deity to use her full strength to control the army, if it is not for the ancient passage, it will not be able to threaten Li Xiaosen.

Thinking about it carefully, what really makes Li Xiaosen feel a threat to life and death at present is the old man in the ancient passage who chased and killed Qianqian.

Li Xiaosen had just accidentally eaten the fruit of ancient ability at that time, and his body had undergone great changes, just as his professional attributes were being reshaped, to a certain extent, Li Xiaosen at that time had temporarily returned to the awakening stage, and he was not even as good as a first-level ability.

Facing a professional with first-level ability, he naturally exceeded the third-level boundary, if it weren't for the old man's beastly nature, if he wanted to be strong against humility, Li Xiaosen would not have had a chance to kill the other party.

Because according to the theory of the three-level boundary, Li Xiaosen at that time could not defeat or kill the other party in a head-on confrontation no matter what.

Thinking of this, Li Xiaosen felt that there seemed to be some thought in his mind, which was about to emerge, and he vaguely grasped something.

But the distance of three kilometers is coming to an end, and there is no time to think about it.

Li Xiaosen launched an extremely fast attack with all his might, and the speed burst out, pounced on the battle group of Minister Ruling and Long Xiaoliu......

......

......

"Alright, there are three things we need to deal with right now-"

A moment ago, Commander Lear saw Li Xiaosen running away, although he was surprised and puzzled, he didn't look at it much, quickly retracted his eyes, clapped his palms and said, "First, these five mountain gates are walking in the world, but they can't let them really die; second, the movement here in the branch is too big, in order to prevent the riot from spreading and causing chaos, the scene needs to be controlled; third, let the news of the disappearance of the seniors, I have already reported it, wait patiently." ”

Commander Lear came on behalf of the military cabinet this time, and his performance so far has been relatively decent, although he is inclined to the academic school, but he has never really acted.

But he has a clear mind and rigorous thinking at the moment, and there is naturally an irresistible majesty between his plain words.

Long Qi'er had an appreciative look in her eyes, nodded and said, "Yes, then I'll help the five worlds walk and heal first." ”

Commander Lear nodded to Long Qi'er to express his gratitude, and then said, "Charles, Yiyi, you two go to assist the executive department of the cultivation branch and stabilize the situation. ”

He turned his head to Qian Qian and said: "Your Highness, don't be impatient, I see that Senior Lan is not injured, but she fainted after too many mood swings, and when she wakes up later, everything is at her command, and any arrangements will be followed." ”

Qian Qian was also in a state of confusion, and Zhengse said: "Commander Lear doesn't have to be humble, Aunt Lan is in a mess because of her uncle's disappearance, even if she wakes up, she is not suitable for command, everything present is at the mercy of Commander Lear's arrangement." ”

Commander Lear smiled and said, "It's a very moment, then I'm not pretentious." ”

In my heart, I thought: When Commander Lu Ming sent me out, his attitude was more inclined to the academy, but at this moment, he sent a hundred soldiers to help the Minister of Adjudication, what the Lord Commander meant by him, I am a little confused.

I secretly made up my mind that I would never stand aside in the future, and strive not to offend both sides.

Compared to the cultivation academy and the United Family that are divided into two factions, the Bingge is basically a one-person hall led by Lu Ming, and since the attitude of Commander Lu Ming is ambiguous, Commander Lear does not dare to decide on his own, and everything is only according to the arrangement of Commander Lu Ming when he set off.

"Actually, looking at the situation, Lu Ming's latest meaning should be on the side of the Minister of Adjudication, otherwise he would not have sent those hundred soldiers. ”

Commander Lear couldn't help but think, "In the current situation, it is estimated that the minister's side will win more or lose less, or I will simply -"

But after thinking about it, I decided not to act rashly for the time being.

The mantra of Lu Ming's command couldn't help but resurface in his mind: "The world is unpredictable, don't seek merit, but seek no fault." "The first time Commander Lear heard this, it was when he was young and vigorous, and he was very disapproving. Now that I have experienced more and more things, the more I feel how true this sentence is.

At this time, a voice asked, "Just wait for the result, don't you have to do something?"

It was Li Xiaoqian who spoke.

She pointed to Li Xiaosen, who stopped in the distance and was gathering momentum, and said, "Come with me and help my brother." And ......" She looked at Long Qi'er again, hesitated, but still insisted, "Those five villains were going to kill my brother just now, and my brother has already spared their lives, do you still want to help them treat?"

Long Qi'er frowned slightly, thinking that this is too childish, how can you, this little girl, understand how much of a consequence it will be if the five world walkers are abolished and even killed?

Qian Qian opened his mouth and said: "Xiaoqian - you are Li Xiaosen's sister, I will call you by your name directly - these five are all walking in the world, although they are the same age as us, and their level is only one level, but they have great potential, and they are all characters that Shanmen values very much." Long Qi'er helped them heal their wounds, but it was just to avoid causing more trouble. Long Qi'er didn't bother to explain more, and had already walked over to help heal her injuries one by one.

Li Xiaoqian was a little confused, she clearly saw that Long Qi'er's uncle Long Wu was fighting against the Daomen Ghost Sword, but why did Long Qi'er still help the five worlds walk? Although she is very smart, it is in the academic and spiritual sector, but in terms of human feelings, she is very innocent, and many complicated things in the world are difficult for Li Xiaoqian to understand at present.

However, Qianqian said softly, so she nodded, and accepted it, but thought in her heart: "Fortunately, my brother was ruthless enough just now, otherwise these five people would have recovered from their injuries and would have to shout and kill again." ”

Although Li Xiaoqian is kind, she is actually a person who has a very clear division of grievances, in her small heart, all those who want to kill her brother are unforgivable, so she has no mercy at all for the five people who walk in the world and do not die.

But if these five people just came at her, with her temperament, she would not be able to bear to be ruthless.

After thinking about it, he asked again: "Don't talk about those five villains, but what about my brother, why don't we help him fight the adjudicator together?"

Qian Qian was silent, and he didn't know how to answer for a while, not to mention that Lan was unconscious, even if he woke up, if he didn't have a military formation of sufficient quality, how could he confront the Minister of Adjudication who led a hundred soldiers in the Arsenal?

Captain Lear smiled slightly, and said lightly: "The 'third-level boundary' is there, and the ruling minister and Long Xiaoliu are both third-level peak powerhouses, extremely close to the fourth-level, how easy is it to intervene?"

Li Xiaoqian had also heard the saying of the third-level boundary, and said seriously: "The challenge limit of a first-level professional is the fourth-level. According to the 'three-level boundary' theory, even if both the ruling minister and Long Xiaoliu are fourth-level, there is a theoretical possibility of challenge. ”

The more serious strength of an academic beautiful girl naturally came out.

Captain Lear was stunned for a moment, he really rarely faced someone like Li Xiaoqian who had a hard idea with him after being in the professional circle for so long.

His attitude was ambiguous, and he didn't stand aside easily, but he had a really good temper, and he only smiled slightly and didn't answer.

One of Lear's subordinates raised his eyebrows and shouted: "If you can challenge it in theory, can you really challenge it?" Who do you think your brother is, the pride of heaven at the level of the heavenly list? In terms of potential, our family commander is not inferior to the heavenly list, and it is only because of the upper limit of his profession that he cannot be on the same list as those people, but he is not sure to meddle in the two battles over there, let alone your brother?"

This person followed Commander Lear to find Lan and Qianqian before, but he didn't see the scene of Li Xiaosen fighting five people alone, but only when the five people in the world were defeated under the joint efforts of Li Xiaosen and Long Qi'er.

Commander Lear frowned, raised his hand to signal his subordinates not to say much, then looked at Li Xiaoqian, and said: "I don't know much about the Dark Spawn soldiers, but looking at your brother's injury repair ability, I'm afraid it's close to the 'critical blood limit', how many ingredients in his body are nightcrawlers now, and when the matter is over, there will naturally be someone to test it." My personal advice is that he'd better be like us now, and stop acting rashly, otherwise he will forcibly intervene in a battle that he can't intervene in, and if the situation worsens or even goes out of control, then ......"

The rest of the sentence is not continued, but the meaning is clear.

Li Xiaoqian snorted, turned her head to look at Qianqian, and asked, "His Royal Highness Qianqian also thinks that my brother is a descendant of the Nightkin and is a monster?"

Qian Qian is probably the only person present except Li Xiaoqian who did not have fear and jealousy of Li Xiaosen because of the battle between Li Xiaosen and the Five Great Worlds just now, but her identity is different from Li Xiaoqian, and in her heart there is not only Li Xiaosen, but also Blue, Jean, her younger brother Katz, and the future of the entire United Family.

She really couldn't care about it so much, she was already confused, and when she was asked by Li Xiaoqian at this time, she didn't know how to answer for a while.

At the same time, although Qian Qian did not feel guilty about Li Xiaosen's dark descent issue, he also recognized Captain Lear's theoretical statement of "three-level boundaries".

A disappointed expression appeared on Li Xiaoqian's face, but she quickly suppressed it and hummed again.

This was the first time she had seen the complex human heart in the human world, and she thought to herself that the witch hunter had just shot at Katz, or her brother had rescued her, but now? When her brother needed help, she pushed back one by one! And thought that her brother had done so many things in the Dehua High School incident and in the club war! Why did these people either want to kill her brother or stand idly by?

For a while, Li Xiaoqian couldn't figure out so many questions, she only tried to tighten her red face, and only thought in her heart: I can't cry, I can't embarrass my brother, if you don't help my brother, I'll help myself!

Turning around, he strode towards the core battle group, trying to hold his head high and his chest up, but he couldn't help but feel sad in his heart.

In the field of vision that only Li Xiaoqian could see, Li Xiaoqian's face was indifferent, and she followed beside her step by step.

According to Teacher Xu Kaili, every owner of the blood inheritance ability has his own demons, which can also be said to be another self, Li Xiaoqian thought to herself that the girl in Xuanyi who was exactly the same as herself was probably my inner demon.

Looking at Li Xiaoqian's back, Qianqian shouted: "Hey, you...... Don't be impulsive. Captain Lear and the others only glanced at it a few times, and then ignored it, what can a little girl who is not a professional do?

As for her brother Li Xiaosen, strong is really strong, but it is an unstable force after all. In fact, like Long Qi'er, she was not bad to Li Xiaosen before, and she also gave him Daomen pills during the safari. Captain Lear also spoke for Li Xiaosen, and so did Charles. But after seeing Li Xiaosen's previous battle, these people's hearts actually had subtle but crucial changes.

The owner of the blood inheritance ability is already extremely controversial, not to mention a person like Li Xiaosen who is suspected of approaching the critical blood limit! This is a guy who can transform into a nightkin at any time, a guy who can turn into an enemy at any time!

Of course, the most important thing is that in the end, this battle will still fall on the duel between Long Wu and Ghost Sword, which no outsider can interfere with.

At this moment, a strange scream and whistling sound sounded between the heavens and the earth, like an ultra-high-speed new-age aircraft flying at full speed and low altitude!

The sound was repeated nine times in a short time, louder and softer, softer and louder, and so on nine times, and finally disappeared and could not be heard, because the frequency was beyond the limits of the human ear's range.

Li Xiaoqian, Qian Qian, Captain Lear, Long Qi'er, Katz, Charles, Yiyi, and even the five Tianxia Walkers who fell to the ground but were still conscious, all felt something and looked up at the air.

I saw a figure like lightning, like a shadow, like wind, like light, flying overhead.

The speed is so fast, from the perspective of a professional, it is impossible to clearly capture the trajectory of that figure in a hurry!

Bang bang Except for Li Xiaoqian and Qianqian, who were wrapped in a layer of soft power and were not affected, the others were caught off guard and were all shocked.

"That'...... That's ——?"

Qian Qian was busy protecting Katz and Lan, and at the same time wanted to reach Li Xiaoqian, thinking that she was Li Xiaosen's sister, but she couldn't really let her get hurt next to me, so he didn't look carefully at the sky, and didn't realize who was the initiator of this storm.

However, Captain Lear and Long Qi'er are both strong and well-established professionals, and in terms of talent potential, there must be a gap between them and the ten people on the Heavenly List, but in terms of solid foundation, they are actually not bad at all.

So they saw it, that unbelievably fast figure, isn't it Li Xiaosen?!

Li Xiaosen, who ran out of 3,000 meters just now, rushed back in this way?

It's too fast.

Normal people can't see clearly, and people who see clearly don't have time to react.

Li Xiaosen had already flown by at great speed, and he was unstoppable, crashing into the battle group of the Minister of Adjudication and Long Xiaoliu!
