At this moment, Don was standing in front of a steel gate, which was pitted with a dozen depressions, as if it had been shelled.

There were a few security guards around Don En who seemed to want to rush up and block Tang En with the electric baton in their hands, but Tang En was put down in an instant.

Not far away, the child-like researchers, who were frightened, but seemed to have seen some incredible scene, and whose curiosity exploded, looked at the hundreds of small steel balls floating around Donn, and seemed to have forgotten to breathe.

Tang En wore a fox mask, and after entering ARGUS, he directly turned on the ability, he had no intention of hiding his strength, after all, although Tang En's ability was strong, but it did not have too strong protective ability, and one bullet was enough to kill Tang En.

In particular, Don speculated that there was a Japanese government as a backer, and it was likely that the lower echelons were protected by self-defense force members with loaded guns, so Tang En would not be careless.

As for how much turmoil Tang En will bring to the current world and how much shock and panic the scientists of the whole world will be caused by the ability to show his abilities later, Don doesn't care at all.

Anyway, he is here to complete the task, and after completing the task, others will leave this world, can these guys still chase down Donn's world?

Tang En just wanted to get rid of these troubles on his body as soon as possible, and he had a feeling that if he didn't get out of these troubles as soon as possible, he might not be able to get out of them later.

"This thickness is definitely not an ordinary enterprise-level security door. It's a pity that the small steel ball is still too small to break through this gate. ”

A small steel ball flew backwards under Donn's control, and did not stop until it flew out of the gate and was a hundred meters away from Donn. After that, the small steel ball suddenly accelerated, faster and faster, flew a distance of 100 meters, passed by Tang En, and bombarded the steel gate at a speed of more than 3000m/s.

"Boom!"

The small steel ball shattered into drops of molten steel in an instant, leaving only another groove on the door.

Seeing that Xiao Gangzhu was helpless against the gate, Tang En could only walk to the gate by himself and put his hand on the gate.

This is a manifestation of Donn's delicate operation.

Donn's ability to generate an almost infinite amount of pressure, and Donn can use this feature to cut hard objects. However, this operation requires a high degree of continuity, and Don must cut through it with his ability little by little according to the coordinates, and although it is indestructible, the speed is worrying.

As soon as he started, Tang En understood why his small steel ball cannonball shells had no way to take this steel gate, this gate was built with twenty centimeters thick armor plates, where is this gate, it can be said to be a fortress.

Moreover, this is still the thickness of the first layer, and if the information that Don got from the novel is correct, Akihiko Kayaba also has his quantum computer, SAO's server, which is on the fifth underground floor.

A minute later, a large piece of armor fell with a bang, Don En did not directly enter the second layer, the first to move was the small steel ball beside him, and more than a dozen small steel balls instantly broke through the speed of sound and rushed into the second layer.

"Knock, knock, knock!"

The small steel balls shot at different targets, and suddenly a miserable scream came.

It turned out that Tang En faintly detected that just behind the gate on the second floor, there was a group of security personnel dressed in professional explosion-proof suits, with explosion-proof shields and firearms loaded with rubber bullets in their hands.

Although they are not lethal weapons, Tang En's defense power is only at the ** level, and of course he will not allow this kind of attack to appear in front of him.

More than a dozen small steel balls instantly pierced through all the explosion-proof shields and shot past the side of this group of security guards, and the powerful air flow directly completed the formation, and the security personnel who were about to shout to give Tang En the last chance to surrender knocked into the air one by one.

Several people still wanted to struggle to get up, but Tang En's mind moved, and he exerted his abilities one by one, causing them to faint from the concussion.

……

Seijiro Kikuoka watched all this dumbfounded, watching this man with a fox mask as if he was in and out of a no-man's land, instantly defeating the security team of thirty people on the second layer who was responsible for blocking the attack, and the remaining twenty scattered squads also strangely lost their combat ability one by one.

It's as if everyone dies instantly if they are seen by this intruder.

"What is this, Grim Reaper? I worked in the most scientific laboratory of G, and I saw the most unscientific scene? ”

The corners of Seijiro Kikuoka's mouth grinned, he didn't know whether he was crying or laughing, he was a strong man, and he was strong enough to always be able to control everything and manage everything in an orderly manner, but now, things were clearly beyond his control.

Even beyond his knowledge.

"Reinforcements...... Belch...... Something attacked my brain...... I...... Yes! ”

The security captain on the second floor was also "killed", and all that came from Seijiro Kikuoka's headset was a rustle. Seijiro Kikuoka's always smiling face finally lost his smile.

With a gloomy face, he thought for a few seconds, and said to the guards on the third floor: "Shoot directly, shoot and kill!" ”

"Yes!"

He was answered by the neat and deep voices of the elite troops.

……

Don came to the gate on the third floor, and the underground structure of ARGUS took on the shape of a pyramid, and the area became larger the further down it went. Compared with the first layer, the second layer is obviously much more specialized, and there is even a complete set of supercomputers in the center.

Don doesn't know the name of this supercomputer, but it is also the leading product of the Japanese G, but its current fate is to be placed on the second layer as a cover, and the entrance to the real third layer is actually on the back of this supercomputer.

Using the entire huge supercomputer as a doorway can be described as a big deal. If terrorists who don't know the truth attack ARGUS, I'm afraid they will also regard this supercomputer as a core target, but in fact, even if this supercomputer is blown up, it will only cause a little trouble for ARGUS.

If it weren't for Donn's knowledge that there were five floors underneath ARGUS, and his ability to detect the movement of many people beneath his feet, Donn might have been confused by the supercomputer.

Don closed his eyes and listened quietly, and with the detection of his ability, he seemed to see what many people were quickly preparing behind the gate on the third floor, which were small squares that seemed to be connected with something. After making preparations, the men quickly retreated and found cover.

"I see, knowing that the armor plate can't stop me, have you prepared an open-door kill for me? Unfortunately, I have a gift for you too. ”

Beside Donn, there was a cube of metal floating around, which was the material that Don had cut from the door of the armor plate on the second floor.

At this time, Donn's finger was on the metal block, and pieces of metal debris quickly fell, and the metal block of the cube quickly deformed, and finally turned into a perfectly smooth sphere, with a mass of about a kilogram.

All the cameras on the second floor are facing Don, and they become the eyes of Seijiro Kikuoka, observing Don's every move, and Don has already discovered all this, but Don has no intention of hiding it.

Even, Don lifted the metal ball up and let Seijiro Kikuoka, who was behind the camera, take a good look at how skillful his means of cutting metal were.

……

Seijiro Kikuoka's face was pale, his fists were clenched, he could see Tang En's every move clearly, how could he not understand Tang En's provocation?

For many years, since Seijiro Kikuoka became a direct subordinate of the top of the Japanese government, few people dared to be so disrespectful to him. If the other party is a high-level talent like Akihiko Kayaba, it would be fine, and he Seijiro Kikuoka still has the strength to tolerate these geniuses.

But what is this person now? An intruder, a terrorist, a man with eccentric powers who ran out of nowhere!

Is he qualified?

Yes!

Seijiro Kikuoka took a deep breath and forced himself to calm down, he observed Tang En's actions all the way, it was obvious that all of Tang En's actions were planned and then moved, as if he could predict the prophet, he must have a purpose in cutting this metal ball!

What is his purpose?

Seijiro Kikuoka thought quickly, he is the supreme commander here, and he must be responsible for the lives of his soldiers, for the safety of the entire research institute, and for the lives of these researchers!

Full submersion technology this project, but the key to the re-entry of the top power of the Japanese G, must not be lost!

What the hell is he going to do!

"Cannonballs, cannonballs!"

At this moment, Akihiko Kayaba's voice sounded in the ears of Seijiro Kikuoka, and Seijiro Kikuoka was shocked and figured everything out!

That's a cannonball!

Small steel balls can be used as cannonballs, but large metal balls should be used as cannonballs!

"If a metal ball of this mass is used as a cannonball, it can still hit the speed just now...... Retreat, everyone retreat, give up blocking, he is not something you can stop! ”

Seijiro Kikuoka suddenly woke up and yelled into the headset, his order was so surprising that the elite Self-Defense Force members in charge of the third-tier guards couldn't understand this order for a while.

After all, they don't know what the enemy they are facing. They thought there was a powerful armed force on the other side, but in fact it was just a person from another world with powerful abilities, Don.

The one-kilogram cannonball flew behind Donn, opened a limit distance of 100 meters, like a bow and arrow with a full string, and then suddenly accelerated, 34 milliseconds, 5.7 meters later, the cannonball broke through the speed of sound. After the extreme acceleration of 200 meters, the speed of the shell once again exceeded 2000 m/s!

This speed has surpassed the limit speed of a human cannon that can shoot cannonballs!

The steel projectile carried a terrifying torrent, tearing everything in front of it in an instant, and the 500mm armor plate could not stop the terrifying shell at all, and a big hole was broken in an instant.

The terrifying light and heat swept the various bombs laid out by the Self-Defense Forces, scattered into the third layer, and then detonated, and in less than a second, the third layer had become a sea of fire.

Seijiro Kikuoka looked at all this in a daze, at this moment, Tang En's shelling, artificial shelling, completely subverted his common sense and made him lose the confidence to resist.
