Martial artists are divided into star ratings, according to their strength, they are divided into one star to nine stars from low to high, but nine stars are not the apex of martial artists, and there is a more powerful level above this - the inner qi realm.

The Inner Qi Realm is an existence located at the pinnacle of martial arts.

A martial artist who has reached the nine-star level, after training his physical body to the extreme, has a certain probability of producing internal qi in his body, and the existence of internal qi can greatly strengthen the strength, agility and physique of the martial artist, so that the physical fitness that has reached the limit will break through again, and he will have unparalleled strength between his hands and feet.

Every inner qi realm can be called thousands of enemies, or even ten thousand enemies, and this refers to star-level martial artists, no matter how many ordinary people there are, they can't pose any threat to the internal qi realm, even if they are armed with hot weapons.

As far as the internal qi realm is concerned, thermal weapons have long lost their threat, even if it is a tank and artillery, only a large-scale star martial artist, or a martial artist who is also an internal qi realm, can deal with the internal qi realm.

The internal qi realm has become the core force guarantee of a country's power, which is also the reason why the martial arts of this world are so prosperous.

These are all things that Du Mu only learned after entering Xingluo Academy.

He didn't expect to see a real inner qi realm in Black Leaf's base!

Although Gu Yu has the strength to surpass the Nine Stars, which is comparable to the Inner Qi Realm, it seems that he relies more on his extraordinary ability, and it is still unknown whether he has reached this level.

On the contrary, Liang Yuan is a genuine inner qi realm.

Only a true Inner Qi Realm powerhouse could possess such terrifying destructive power with his physical body alone, which was no different from a humanoid hurricane.

Du Mu glanced at the afterimage of the two of them colliding at lightning speed, and decisively left the vicinity of the pothole.

He didn't want to be implicated in the battle between two powerhouses at the level of the Inner Qi Realm, and it was estimated that the slightest leakage of the aftermath would seriously injure him.

Back in the lab, Hilson is still fighting the Faceless.

Originally, there were less than seventy faceless people left, and now there are only forty left, but Hilson has also suffered some injuries.

With his five-star level strength, it was always a bit difficult to deal with more than sixty three-star intermediate ranks.

Taking Hilsen back, Du Mu personally took action to deal with the remaining faceless ones, and then turned his head to look at the man surnamed Zhao on the side, and asked coldly: "In addition to Liang Yuan, how many martial artists above six stars are there in the base?"

"There are less than 10 people, except for one nine-star martial artist and two eight-star martial artists, the rest are seven-star martial artists. The man surnamed Zhao immediately replied that after eating a five-finger gun, he became much more honest.

"Where are they on weekdays? 4th and 5th basement?"

Seeing the man surnamed Zhao nodding, Du Mu couldn't help frowning slightly, fell into deep thought, and only said in a deep voice after a while: "Go, take me to the place where the relics are stored on the fourth basement floor!"

The man surnamed Zhao had a bitter face, but he didn't dare to disobey Du Mu's order, so he had to go forward and lead the way.

Du Mu disliked him for being too slow, so he simply grabbed his collar and lifted him up, and ran fast while letting him show the way.

The two hurried all the way, and soon arrived near the warehouse where the man surnamed Zhao stored the relics in the mouth of the man on the fourth floor of the basement, and heard the sound of fierce fighting from a distance.

"Sure enough, someone has already taken the lead!"

Du Mu was not surprised, he could catch the man surnamed Zhao to show the way, and the other members of the annual ring could naturally catch the core members of the base and ask where the warehouse was.

It's just that an important place like this is usually guarded by a strong armed force, and presumably those members of the annual ring who arrived first are in a fierce battle with the guards of the warehouse.

Rushing around the corner, Du Mu slowly stopped and looked up.

The entrance of the warehouse was opened, and the heavy metal door had already turned into a twisted iron plate, lying quietly on the ground, the edges were full of sharp fractures, as if someone had torn it off the door frame with brute force, and the corners of Du Mu's eyes twitched for a while.

When he came back to his senses, Du Mu did not go into the warehouse, but carried the man surnamed Zhao to find a place to hide his figure, and then looked into the warehouse.

It is said to be a warehouse, but it is actually similar to the previous laboratory, except that there is no control room isolated by a glass wall on the right-hand side, and there is no metal door on the front wall, but a square translucent cubicle, about thirty or forty.

Many of the cubicles had been opened, and the contents were long gone, leaving only four or five cubicles still closed.

In addition, there were many bloody corpses lying on the floor of the warehouse, and in the center, four figures were fighting fiercely, raising their hands and feet to invade everywhere, and the cold was permeating.

Du Mu looked fixedly, three of the four were like him, they all covered their faces, and they were all members of the annual ring.

The last man was a stout man with short hair, more than two meters tall, wearing black trousers and a white shirt, with muscles that seemed to be made of steel, full of explosive power, holding the shirt tight.

At this time, the three members of the annual rings are teaming up to besiege the short-haired man.

His gaze fell on the short-haired man, Du Mu's eyes couldn't help but stare at him, and he felt an indescribable sense of oppression from the bottom of his heart.

"Who's that guy?"

Du Mu turned his head to look at the man surnamed Zhao, who naturally knew who he was referring to, and hesitated when he heard the words, before responding, "Qin Jin is the core cadre of the base. ”

"Strength level?"

“...... Eight-Star Warrior!"

Du Mu inhaled without a trace.

The man surnamed Zhao glanced at Du Mu vaguely, and then couldn't help but have a glimmer of hope in his heart, with Qin Jin here, he should be able to save him from this guy's clutches, right?

Du Mu didn't pay attention to what the man surnamed Zhao thought, but watched the battle of the four intently.

The three annual ring members who besieged Qin Jin should be seven-star martial artists, but the three of them joined forces and were faintly suppressed by the former.

Moreover, Du Mu's eyes were sharp, and he found that almost all the corpses on the ground were members of the annual rings that covered their faces, and most of the deaths were fatal injuries such as twisted necks or collapsed sternums, and it was obvious that they were killed by someone who hit the vital point with a heavy hand.

Judging from the scene in front of him, there is no doubt that it is Qin Jin's handiwork.

"The strength of the eight-star martial artist is so strong, and he can still kill so many people when he is besieged?"

While watching the battle intently, Du Mu muttered to himself in shock, and suddenly slapped his forehead after a moment, "I almost forgot that there was a detector!"

He hurriedly activated the detector and stared at Qin Jin intently, and the corresponding data suddenly appeared in his field of vision.

'Combat Strength: 11749'

Du Mu's breath was stagnant, and his combat strength of more than 11,000 was more than six times that of him!

Even if you combine the combat power of him and the three gray servants, they can't compare!

Looking at the other three seven-star martial artists, only one is more than eight thousand, and the remaining two are more than six thousand and more than five thousand, which are far inferior to Qin Jin.

"Hey, no wonder so many people can't beat him!"
