After being silent for a long time, the police director said coldly: "Arrange for me to search the first ten floors!" ”

The subordinates hurriedly complied, they all understood that the director of police was preparing to fill in with human lives, and use the lives of those low-level martial cultivators to find that Xiao Ran. {We don't write novels, we're just web text porters-

At this time, Xiao Ran had already sneaked into the ventilation duct of the underground base.

He found that the air exchanger was not connected to the network, and that he had to go to the air transfer room himself to solve the problem, which was fortunately located on the ninth basement floor, which he had just conquered.

When he came to the ventilation duct, he found that things were more difficult than he had imagined, and that he had to enter the air transfer room through the ventilation duct.

Ten meters in diameter and 30 meters deep, there are two exhaust fans in the middle of the ventilation duct, which are made entirely of stainless steel and rotate very fast.

Moreover, the ventilation duct was completely constructed from the Stone of Confinement, and the strength of the martial cultivator was of no use at all.

The only way to get into the air conversion chamber through two exhaust fans that look like meat grinders is to stop the power and let the exhaust fans run to a standstill.

However, the power is controlled by the 126th floor of the underground base, and Xiao Ran has no way to cut off the power now.

Apparently when the underground base was first built, the builders took all the problems into account.

If it was an ordinary person, even if it was an S-level super strong, he would have been desperate by this time, but Xiao Ran was different, he had a super brain, and he had a brain domain development degree of up to 29%.

Gritting his teeth and looking at the exhaust fan below that seemed to be a guillotine spinning, Xiao Ran quickly calculated his falling speed and the rotation speed of the exhaust fan in his mind.

His brain is like the most sophisticated computer at this time, using the information collected by the supervisual and ultra-auditory senses of extrasensory perception, and quickly calculates solutions in his brain.

"Acceleration 13.56, initial velocity 75.23 m/s, starting position ......"

Rows of data eventually list a final solution.

After the plan was calculated, Xiao Ran was instantly silent, because he found that this was an impossible task.

Jumping from a height of thirty meters with an acceleration of 13.56, and when he was imprisoned by the Imprisoned Stone and lost the strength of a martial cultivator, this impact would definitely kill him directly.

"Damn! Why don't I be an S-Class Wind Adept! Xiao Ran slapped the wall heavily, if he was an S-level super strongman, he could use the wind ability to directly evacuate the air in the underground base, but his current mental power was only B+ level, and he couldn't resist the suction of the exhaust fan to drain the air.

Boom!

His palm slapped against the wall, making a sound of gold and iron colliding, the eighth layer was the defense level of ordinary human warriors, and the building material on the wall turned out to be made of metal.

Xiao Ran then remembered that the A-rank martial cultivator had just pulled a steel plate on a wall and attacked him.

With a flash of inspiration, the physical power of Xiao Ran's God Realm exploded, and it directly tore the wall as if it was a god of destruction, tearing a steel plate with a diameter of two meters off the wall.

Rumble!

Xiao Ran threw it casually, and the steel plate flew directly into the ventilation duct, and then fell straight down.

The acceleration is 13.56, and the initial speed is 75.23 meters per second, because of Xiao Ran's supercomputing ability and super perception ability, the steel plate fell exactly on the key part of the exhaust fan.

Click!

The exhaust fan was jammed by the steel plate, sparks in all directions, and made a loud writhing sound.

Rumble!

Xiao Ran relayed again and again, and threw down a steel plate.

Bang!

The weight of the two steel plates directly crushed the exhaust fan and fell down the ventilation duct.

The first exhaust fan carried two steel plates plus the impact of the fall, directly smashing the second exhaust fan, and finally the two exhaust fans fell to the platform thirty meters below.

Xiao Ran found a rope and followed the ventilation duct to the platform.

As soon as he landed on the platform, Xiao Ran felt a tremendous suction, if it weren't for the rope tied to his body, this suction force would be enough to suck him underneath, and then be torn to pieces by the exhaust fan below.

The exhaust duct was like a huge typhoon eye, and the tearing force of the air almost suffocated Xiao Ran.

Along the platform, Xiao Ran carefully moved his steps, and finally came to the air conversion room according to the architectural drawings.

As soon as he entered the air conversion room and closed the door, Xiao Ran gasped for air.

After taking a breath, Xiao Ran found the control switch in the air conversion room and directly turned off the air exchange system of the underground base.

Xiao Ran knew that the underground base still had a backup system, but he had already paralyzed the underground base's network, and if the underground base wanted to restart the air exchange system, it would only be a power outage and send someone into another air conversion room.

If the underground base dares to lose power, then he can take the opportunity to sneak directly into the 123rd floor underground through the ventilation duct.

Climbing back to the eighth floor along the rope, Xiao Ran waited, waiting for the reaction of the underground base.

In the Babylon surveillance room, the police director soon received a report from his subordinates that the air exchange system was turned off, and everyone in the underground base would die of lack of oxygen in half an hour.

As Xiao Ran expected, the police director was in a dilemma.

In order to restart the air exchange system, the power must be turned off, but if the power is turned off, it will undoubtedly give the intruder the opportunity to invade down the ventilation duct.

"Damn! Babylon's building blueprints must have leaked out! The person who leaked the drawings should be shot directly. The police superintendent found that no matter how he chose, he could only stall for time and could not solve Xiao Ran's problem.

Sighing helplessly, the police director said coldly: "Let Musashi take someone to the ninth floor and kill that Xiao Ran for me!" ”

Musashi is another A+ rank martial artist in the underground base in addition to the police director.

The order was given, and Musashi took four A-rank martial cultivators to the ninth underground floor.

As time passed, the air in the underground base gradually thinned, and except for the martial cultivators, ordinary soldiers felt that their hands and feet were weak, cold sweat began to appear on their foreheads, their eyes began to glow, and their breathing became more and more rapid.

This is a contest of patience, the police director is anxious, Xiao Ran is more anxious than the police director, because the education chief promised an hour, the heart has passed fifteen minutes, if the people below do not act according to their own conjectures, then this operation to seize the meteor fragment can only end in failure.

Two minutes.

Five minutes.

Ten minutes.

Another fifteen minutes later, a prompt came from the super brain, and one A+ rank martial cultivator and four A-rank martial cultivators appeared on the tenth layer.

Xiao Ran took a deep breath and stood at the entrance of the tenth and ninth floors.

At the same time, Xiao Ran's extrasensory ability penetrated through the ninth layer, probing the activities of the martial cultivators on the tenth layer of passages.

One A-rank martial cultivator, two A-rank martial cultivators, eighteen B+ level and below martial cultivators, all the guards were still there, but their expressions were obviously relaxed, because the appearance of A+ martial cultivators in the underground base made them relax their vigilance.

Smack!

With the sound of footsteps, the first thing that appeared was four ordinary human warriors holding shields, these four shields were composed of the Stone of Imprisonment and the Special Aid Alloy, which could effectively protect ordinary human warriors from being attacked by martial cultivators, at least for a few seconds, the attacks of martial cultivators could not be broken

Moreover, the four ordinary warriors holding shields also wore exoskeleton power armor, which could withstand the attacks of stones or iron plates thrown by martial cultivators.

Seeing the four shields and the outer skeleton power armor, a smile appeared on the corner of Xiao Ran's mouth.

As expected, even the tightest fortifications will be porous due to human stupidity.

These shields and exoskeleton armor were obviously specially prepared by the guardians to fight back against the invaders, but I didn't expect that this would provide the invaders with convenient conditions for the invasion.

The Imprisoned Stone Shield and the Outer Skeleton Power Armor could naturally block Xiao Ran's attack, leaving him with no way to attack when the martial cultivator came from the tenth layer to the ninth layer.

However, Xiao Ran was not ready to attack them, but watched with a smile as the group of nine people came to the ninth underground floor.

"Xiao Ran! Your time of death has come! Musashi, the A+ martial cultivator at the head, released an energy force field and crushed Xiao Ran.

In the information of the Dongying people, although Xiao Ran can use dual-system abilities, he is still only a C+ level martial cultivator and does not have an energy force field.

Without an energy force field, no matter how talented he is, facing the crushing of the energy force field is only a dead end.

Bang!

With a loud bang, Musashi's A+-level energy force field slammed into the golden bell flowing with Sanskrit in Xiao Ran.

Musashi's expected scene of the golden bell shattering did not appear, the golden bell shook violently, and countless cracks appeared on the surface of the golden bell, but it was hard to withstand his A+ level energy force field.

"It can't be!"

Musashi's eyes widened, and he looked incredulous.

Bang bang!

The energy force fields of the other four A-rank martial cultivators also crashed into Xiao Ran's golden bell.

The golden bell shook more and more intensely, the cracks on it gradually increased, and it was about to collapse, and the golden Sanskrit was like a glue, allowing the golden bell to support it.

Whoosh whoosh!

Just when the energy force field was deadlocked, five secondary air blades shot at the Musashi five.

The faces of the five Musashi changed drastically, and they hurriedly twisted their bodies to dodge the attack of the secondary air blades, but just as they twisted their bodies, they were shocked to find that the five secondary air blades were followed by fifty secondary air blades.

"No ......"

The four A-rank martial cultivators let out a miserable cry, and they were shot to pieces by the second empty blade.

Only A+-level Musashi's eyes flashed, and a silver aura appeared in front of his body.

Bang bang bang!

was taken care of by Xiao Ran, and more than two dozen wind blades shot onto the silver aura.

Puff puff!

It was as if all the secondary blades had hit an impregnable wall, and they exploded into shards in the sky.

Xiao Ran's pupils contracted suddenly, this was the first time that someone below the S-level had blocked the attack of the sub-empty blade.

Instead of dodging, he used some kind of special aura to directly smash the secondary air blade.

"Is it the power of the magnetic field?"

Xiao Ran's heart moved, the reason why A+-level martial cultivators are rarer than S-level super-strong people is because after becoming A+-level super-strong, they either choose to retreat to comprehend the natural magnetic field, or impact S-level.
