The main building of the Myers Weapons Research Institute does not look big, five stories high, the whole is diamond-shaped, the internal space is wide, but it is limited after all, the real R&D center is on the third floor underground, that is the real core, the space of each of the three underground floors is the sum of the five floors of space above ground, after all, if it is not big enough, it is impossible to put too many big guys such as large missile fighter engines.

The fifth floor above ground is the residence of scientific researchers, one room after another, there are also house numbers marked with numbers and English letters, and the center is the rest area, when Qi Mingxuan broke in directly, several scientists wearing scientific research uniforms were standing in the rest area, paying close attention to the battle situation outside.

There were already U.S. troops rushing in the rear, but they were far from being able to match Qi Mingxuan's speed, and they had already opened up a distance.

Several scientists looked at Qi Mingxuan, who had slammed in from the outside, and their expressions were stunned.

Qi Mingxuan quickly glanced at the surrounding environment, rushed to the second floor without stopping, and the gunshots rang out in the rear, Qi Mingxuan quickly rolled on the ground to avoid the bullets, and began to fight back without hesitation.

Several U.S. soldiers who were the first to chase in fell directly to the ground, and the muzzle of the rifle in Qi Mingxuan's hand flicked casually, aiming at several scientists with frightened expressions and firing again.

Dealing with this kind of 'fixed target' that didn't even dare to move, Qi Mingxuan naturally couldn't miss, and when the gunfire fell again, he had already quickly rushed to the second floor.

At the elevator entrance on the second floor, the sound of the elevator cable sliding faintly, the arrow is upward, and it seems that someone is going to come up from below.

Qi Mingxuan sneered, kicked out the moment he passed by, and the powerful foot made the metal elevator door roar violently, and the heavy steel plate instantly recessed and deformed, jamming the iron cable of the elevator, the entire elevator shook violently, and stopped directly between the first and second floors, and the angry roar sounded faintly from the elevator and reached Qi Mingxuan's ears.

Continue upwards.

Third floor!

A large number of U.S. troops finally rushed in, everyone almost didn't even see Qi Mingxuan's shadow, and began to fire wildly at the space upstairs, the first three floors of the building of the R&D base are designed to be empty, there is no obstacle at all, and more than three floors will be separated by the ceiling.

And even if there was a dangerous situation like a ricochet, the U.S. troops were still firing under the orders of their respective commanders, and countless bullets were flying aimlessly in the space of the second and third floors, which was simply stopping Qi Mingxuan from continuing to go up at all costs.

The gunfire outside is non-stop, and the gunfire inside is as irritable, and it is a very lively picture.

Qi Mingxuan struggled, but his eyes became more and more determined, from the reaction of the US military below, he could already see that the top is definitely the residence of the high-level of the R&D base, and it is very likely that the device that can blow up the entire research institute is also on it.

After all, if this thing is installed on the third basement floor, and if it is a neighbor of those missile weapons, it will be too mad, and this thing is a big killer that does not require the environment, put it on it, just enter the password and press it to explode, which is exactly the same as the deterrent effect placed below.

Qi Mingxuan took out all the grenades captured on his body expressionlessly, quickly pulled the line, kept his hands, and seven or eight grenades were pulled away and thrown down by him at the same time.

The first explosions rang out, followed by a series of explosions like firecrackers.

There was a scream in the space below, and the frequency of bullet fire was noticeably reduced.

Qi Mingxuan did not hesitate and went straight to the third floor

"Professor Myers, an enemy has stormed the R&D base, his speed is fast, we will do our best to stop it, but for your safety, please take the secret elevator to the underground space now, my people will deal with the enemy immediately, Professor Myers, please leave as soon as possible!"

When Qi Mingxuan rushed into the R&D base, a rapid warning sound had already sounded in the intercom in the conference room on the fifth floor.

There weren't many people in the conference room, only four, three men and one woman, all middle-aged, who were watching the battle on the arsenal on the big screen intently, bullets flying on the screen, sparks flickering, and the American troops fell one after another, then were replenished by the American troops in the rear, and then fell again.

On the other side, there were only a dozen or so people, and they didn't fall behind in the slightest fight with hundreds of people, which was lively and intense.

When the warning sounded, the four of them were subconsciously stunned, and then the middle-aged man sitting at the front suddenly rushed out, pressed the intercom and said, "I'm Myers, what kind of enemy are you talking about?"

"The arsenal is their target, and so is the R&D base, Professor, let's go!"

The reply in the intercom is unusually fast.

"How is this possible?"

"Oh my God, aren't they together when they attack our base?"

"Hell, it's a bunch of crazy people!"

Three exclamations rang out almost simultaneously.

"Quiet!"

Professor Myers, who pressed the intercom, raised his voice, he was forty-nine years old this year, he was very short compared to the Americans, brown hair, and his appearance was not handsome, but his eyes were very bright, and there was a kind of majesty that people did not dare to look at each other, the three people in front of him were all members of his core team, there were six people in his team, and two of them were still in the underground space at this time, when the battle first happened, they appeared here for the first time, after all, in the conference room, there is a self-detonation device that can make the entire research institute have a security level rated as -A, in the event of war, this is undoubtedly the most important position: "Guys, nothing is impossible, I find it equally unbelievable, but now it has happened, we must leave, the enemy is on its way, you hear it, the enemy is very fast. ”

The three middle-aged men and women who looked a little panicked tried their best to calm down, but their breathing still seemed a little short.

"Mary, you stay, take care of the self-detonation device, the password is 999888, I'll leave it to you here, let's go down." ”

Myers quickly straightened up and straightened his clothes, glancing over the middle-aged lady's body, and then led the other two middle-aged men directly to the secret elevator inside the conference room.

Mary's expression turned pale for a moment.

When the enemy had already rushed up, he stayed here to watch the self-detonation device, and there was no need to think about the end, she quickly ran over, grabbed Myers's arm, and pleaded: "No, Myers, don't do this, don't leave me here, I am your woman, and you have the responsibility to protect me." ”

"No, no, Mary, you're just my lover. ”

Myers shook his head seriously: "And the other party's target is likely to be the arsenal, come here, just to control the self-detonation device, don't want us to die with him, Mary, you can, stay here." ”

"No, they're going to kill me, Myers, I'm going to die!"

Mary screamed in disbelief.

"You're the best guy. ”

Myers's eyes were still serious: "I can't die, I'm working on a very good subject, and I'm about to break through, and the two people next to me can't die either, as for you, Mary, you're a very good woman, but now your role is relatively minimal, so, stay here, let me go, I'm leaving." ”

He tugged at Mary's hands, but didn't move.

Mary shook her head desperately, looking horrified, "No, I don't want to die, Myers, trust me, I'm important to you." I definitely won't stay here!"

"If you don't stay here, you'll die!"

Under the urgency of time, Mels looked irritable, and his patience was completely exhausted, he took out a pistol directly from his arms, slammed it on Mary's head, and said fiercely: "Let go! Damn, you're wasting my time, if you don't stay, I'll kill you right now!"

"No, Myers, you"

Mary seemed to be frightened, and looked at Myers in a daze, and in addition to horror, there was only the most complete sadness and despair in her eyes: "You won't, Myers, no, you bastard!"

"Let go, slut!"

Myers, who knew very well that staying here for a second longer would be dangerous, seemed to be in a mess, pushed Mary's body hard, and said coldly: "Remember, the password 999888, and when necessary, blow up the institute." ”

He quickly walked into the elevator with two other assistants.

In the space on the third basement floor, there is a safe house that can accommodate twenty people, and even if the entire research institute or even the industrial area explodes, it will become very safe to stay there.

"999888? Thank you, I remember. ”

A male voice rang out at the door of the conference room.

Myers, who was in a hurry, slammed down.

"Who?!"

He turned around suddenly, raised the gun in his hand without hesitation, and directly pulled the trigger, resolutely and decisively, without the slightest hesitation.

"Bang!"

"Bang!"

Two gunshots rang out at the same time.

The shadow at the door shook slightly, then raised the gun in his hand, and the next moment, Myers directly covered his wrist and fell to the ground, and the pistol fell far away.

"Who are you?"

"Bang!"

Another shot.

The huge sound of gunfire echoed in the conference room, and Qi Mingxuan had quickly rushed into front of the self-detonation device in the conference room, and said coldly: "I don't want to listen to nonsense, now, everyone don't move, and don't speak, otherwise I will kill you immediately!"

Enter your password quickly.

In the frightened eyes of the four Myers, the sound of the self-detonation device system sounded: "Do you want to activate the explosion system of the Myers Weapons Research Institute immediately?"

Qi Mingxuan's eyelids jumped, if this was to be pressed, it would really explode directly.

He had wanted to change the password so that he could have time to retreat.

After all, no one in this base can be sure that there will be other officers besides Myers who will know the password, and when the time comes, if you kill the four people in the conference room, you just go out on the front foot, and someone rushes in behind to activate the password, then there is really no place to die.

Qi Mingxuan frowned, clicked no without hesitation, and just wanted to ask the people in the room how to change the password, the system voice sounded again: "Canceled, you can choose the timed mode, re-enter the password, and set a new password." ”

Qi Mingxuan was stunned for a moment.

"No, you can't do that!"

Myers clutched his palms and cried out in horror.

If the explosive device is not turned on once, a new password must be entered, and once the new password is entered, only the person who entered it will know, just thinking about it is a very scary thing.

Qi Mingxuan didn't say a word, raised his hand and shot it.

"Bang!"

A shot struck Myers directly in the heart.

Myers' chest was instantly stained red with blood, and he struggled to the ground, his eyes glazed over, and his life was passing quickly.

The remaining two men and one woman completely collapsed, crushing their cries, frightened and helpless.

Qi Mingxuan re-entered the password without hesitation and chose the timed mode.

"The timed mode has been selected, please reset the password, the timer explosion cannot be changed after it starts, it cannot be canceled, please confirm, whether to start the timed explosion mode?"

Qi Mingxuan hesitated.

It cannot be canceled after startup.

In such a situation, it means that the explosion cannot be prevented at all.

And what will happen to the research institute once it explodes?

This is a real disaster.

The current Qi Mingxuan is like holding a Pandora cartridge, once he presses the button, it is a real corpse all over the wilderness.

The corners of Qi Mingxuan's mouth twitched, but what came to mind was the picture of countless Chinese compatriots being slaughtered from today, and the blood-drenched picture dispelled his last hesitation, Qi Mingxuan reset the password, and his finger clicked the confirmation button without hesitation.

Qi Mingxuan at this moment, his eyes were crazy and strange.
