"Dr. B, do you feel like this person is familiar?" The assistant next to Dr. B looked at Zhang Wei's picture on the screen and said with some doubts.

"Huh? When you say that, I really think this bald head is a little familiar! Like, it's right! Isn't he the one who almost succeeded in injecting two source fluids? What are the numbers? 3.3.30.304 yes, it's 304, I remember I signed it at the time! Dr. B also looked at the bald head Zhang Wei who was becoming more and more familiar in the picture in surprise, the profile photo handed over to him below was indeed this person, but now this guy looks more burly, and those eyes full of strength are not at all like ordinary people at the beginning!

"In other words, when our base in City B was evacuated in a hurry, it is possible that this abandoned test subject was successful in the experiment and survived in the environment of those monsters." The assistant speculated as he pushed his gold-rimmed glasses.

"Doctor, they're on -1 floor!" The defense controller reported again, only to see that after destroying all the defense lasers in the hall on the first floor, Zhang Wei led everyone to stand on the blood-red inverted triangle sign, and then the inverted triangle sign without a trace of a gap sighed in surprise and carried everyone down slowly, and next to the inverted triangle sign, Zhang Wei also used the Thor Sword to carve an arrow on the metal floor, pointing at the inverted triangle, so that the people who came in behind could find the entrance smoothly.

"Directly turn on the highest defense mode, I want to see how powerful this test subject can be!" Dr. B looked at Zhang Wei and the others in the elevator on the screen with a hint of expectation.

"Turn on Layer -1 Level V Defense Mode." "The laser cannon defense system is ready." "Electromagnetic rays ready." "The fire weapon is ready." "Level 1 Combat Robot Ready" "-2 Floor Passage Final Defense Opened. "A series of instructions represent that the various attack devices on the -1 floor are ready, if Zhang Wei and the others appear on the -1 floor, they will be subjected to a fierce attack, such firepower, placed on the outside battlefield, without heavy fire support, even an army of thousands of people will not be able to break through. Moreover, the V-class, which represents the highest level of defense against the end of the world, is the strongest mode that surpasses the A-CLASS, S, SS, SSS class, and will be reckless, and it doesn't matter if the most intruder makes a strong attack, or even destroys the facility!

In the picture, the entire -1 floor of the office area has been evacuated, and instead of laser cannons, electromagnetic ray cannons, gunpowder automatic firearms, and special combat robots patrolling back and forth on the ground, these robots are only one meter and three high, the lower plate is a wheel that can rotate 360 degrees, two arms have machine gunners that can rotate 180 degrees, and two muzzles above the shoulders that can shoot electromagnetic rays and laser rays respectively, In particular, there is a small missile hidden in the belly of the robot, although the volume is only the size of a goose egg, the power is not small!

However, although these attacks were very delicate, they were all designed for the original national army, and their designers did not expect that there would be mutant manpower in the world now! I didn't expect a person's strength to become so strong, for example, Zhang Wei, who was controlling the nine fire dragons, walked all the way, there was nothing to stop their progress, those energy attacks or bullet attacks were all blocked by Liu Tieshan's golden shield, and the surface of the golden shield at this time was already pitted, and it was about half thinner by Xiao! And under the ravages of the nine fire dragons, the entire laboratory base was burned into a sea of fire, although the entire base was built with super fire-proof and earthquake-proof materials, but the scorching high temperature was scorched for a long time, and those refractory materials were also burned! As for those defensive weapons, the Thor Sword in Zhang Wei's hand smoked and didn't move every time a lightning bolt passed, and the highest level of defense of the entire -1 layer was almost not threatening except for the small missiles launched by the combat robots! Especially Wang Huo's water system, although it doesn't have much powerful attack power, but if you think about it, those electromagnetic cannons were invaded by a stream of water, causing a short circuit in the current, and the internal structure was burned by their own electromagnetic power, and destroying a high-cost electromagnetic cannon was a stream of water that almost didn't cost money!

At the bottom of the base, a huge special tempered glass jar with a diameter of more than 20 meters is suspended, and in the most central position, there is a huge golden diamond with a diameter of two or three meters and a height of five or six meters. And the huge golden diamond-shaped body trembled slightly, as if it was an egg about to hatch, and the surrounding monitoring personnel saw this, and immediately reported that "Saint Jing has a special trembling, and immediately sedation with strong voltage." "It's good." I saw that in the huge glass cover, a silver metal firing pin suddenly stretched out from the top, and slowly came to the top of the diamond-shaped body called the holy crystal, and then a powerful blue current visible to the naked eye hit the golden holy crystal, and the whole holy crystal trembled violently in an instant, and the strong current lasted for five minutes before it was slowly withdrawn, and the holy crystal that was originally slightly trembling seemed to be dead and silent, without a trace of movement, as if it had lost its vitality, Let the pipes that are attached to the outside of the crystal extract a steady stream of golden force and transmit it.

"Doctor, just now the Holy Crystal had abnormal shaking again, and the voltage was calmed and calm again." Dr. B's assistant said as he looked at the message from his electronic tablet.

"Oh? Let the people below pay more attention and don't make mistakes. Dr. B said as he looked at the video sent from the electronic tablet in his assistant's hand. Doctor, the enemy has destroyed the final defense of the passage to -2 and is now entering -2. The defense controller shouted again, the opponent was too fast! In less than ten minutes, he took out those defenses all the way to the passage into the -2 floor, and the final defense in the passage was a large electromagnetic particle cannon set on top of a metal door! The advantage of the electromagnetic particle cannon is that the damage to non-biological objects is weak, but it is conductive, and the condensation speed is faster, and the release speed is fast, in short, compared to the slow accumulation energy of the laser and then compressed into the specified orbit, it takes much longer than the electromagnetic weapon to launch it through a series of complex procedures, but when these procedures are completed, the speed of the laser beam after disemboweling is several times that of the electromagnetic beam!

When Zhang Wei and the others came all the way to the passage into the -2 floor, the huge electromagnetic particle cannon on the metal door was already ready, and in an instant, the powerful electromagnetic particle force formed a blue electromagnetic ball and flew over! It just so happened that Zhang Wei was behind everyone to block the battle robots that rushed over, and the ball of electromagnetic particles directly bombarded Liu Tieshan's golden shield like tatters, and in an instant, the powerful electromagnetic particles blasted the golden shield! And Liu Tieshan instantly entered the state of bronze body, and under the powerful electromagnetic attack, he flew out of the body in an instant, his whole body flashed with blue electric sparks, lying on the ground and convulsing! Seeing this, a large ball of liquid flew over, instantly invading the electromagnetic particle cannon, only to hear the sound of leakage of "boom", from the mouth of the cannon came out of a stream of green smoke burned by the circuit tube, and Nangong Xue saw Liu Tieshan who fell to the ground and convulsed, and quickly condensed a milky white force, and with a slight wave, the void was wiped from head to foot, and the white healing power fell and entered Liu Tieshan's body, less than three seconds, Liu Tieshan was no longer twitching, Slowly opened his eyes and said, "It's so fucking numb, I can't move for half a day!" It turned out that Liu Tieshan's bronze body still belonged to the metal element, and under the powerful electromagnetic attack, the whole person instantly conducted electricity, becoming paralyzed and unable to move, but the strong electromagnetic particle force still made Liu Tieshan's chest scorched black by electricity, but under the healing power of Nangong Xue, it has been restored, only the large piece of burned clothes on the chest that has been burned reveals the chest full of muscles, which proves the electromagnetic attack just now!

"It's okay, is it?" Zhang Wei asked after killing several combat robots outside.

"It used to be something, but now it's gone." Liu Tieshan patted his chest and said, then looked down for a moment, made sure there was no problem, stood up, and looked at the huge cannon port on the metal door, damn it, no wonder it hurts so much, such a thick cannon port, I really look up to you and me. Liu Tieshan said secretly in his heart.

"Boom!" With a bang, the metal door that entered the -2 floor was blown open, and Zhang Wei and the others entered the -2 floor directly through the blasted staircase passage, and the entire -2 floor was ready to welcome everyone!

"Damn, how could it be so fast!" Dr. B looked at the picture of Zhang Wei and the others in the stairs entering the -2 floor, slammed his fist on the table and said, It was originally expected that it would take at least a few days to break through to the current command floor, the -6 floor, but I didn't expect this guy to destroy the defense devices of the first floor and the -1 floor in less than fifteen minutes, and entered the -2 floor, at this rate, it would not take a few hours for this group of people to appear in front of him!

"I'm going to release those mutant zombies, I don't believe it, even these mutated zombies can't stop this group of guys!" Dr. B looked at Zhang Wei and the others, who had already entered the -2 floor, and ordered. I saw that a large hole suddenly opened from a blood-colored inverted triangle sign in the hall, and slowly crawled out of it a rotten zombie with festering bodies, claws and fangs, this group of zombies is different from ordinary zombies, some of them are actually in flames, or their bodies are full of black water, and some even have flickering electric sparks! As if they had been imprisoned for a long time, this group of hundreds of mutated zombies of different colors crawled out of the passage one by one, standing in place blankly, and suddenly there was an explosion near the stairs, it was the sound of the second-level combat robots, and the violent explosion made this group of zombies seem to have found something of interest, and in an instant all the zombies moved in the direction of the explosion, and some zombies ran at the same speed as athletes!

"What sound?" Zhang Wei listened to the sound of laser cannon shooting and battle robot smashing, as if there was a familiar howl!

"It's a zombie!" Nangong Xue saw the first tall zombie running behind the robot from the side, and exclaimed! How can there still be zombies in this base!

"Zombies? I liked it the most. Zhang Wei licked the corners of his mouth and said, this way of fighting, destroying those lasers and combat robots but not earning a single source point, and spending more than a hundred points of source exchange in order to blow up those metal doors, and now the appearance of these zombies, isn't it really the time to earn extra money for yourself? After Zhang Wei finished speaking, he opened his mouth and spit out a scorching flame, and the nine dragon flames reappeared, dealing with these zombies that were not at the level of a king was as simple as chopping vegetables, if it weren't for the fact that the units killed by the fire phoenix were not counted as his own killing rights, Zhang Wei really wanted to release the fire phoenix and burn the entire base!

The zombie who was the fastest runner who was originally rushing to the front suddenly felt a scorching force rushing towards him, and in an instant, he turned around and ran behind him, but before he could escape, he was engulfed by Long Yan and turned into more than 20 source points to be collected by Zhang Wei, I really can't figure out why you ran so fast? As for the other zombies, they also smelled the smell of human flesh, and all of them rushed towards Zhang Wei and the others in a rage, and the Thunder God Sword in Zhang Wei's hand instantly turned into several lightning bolts, and the heads of the dozen zombies that rushed in front of them were in different places, and those zombies who lost their heads were still strong and crawled forward, wanting to pick up their heads, but in this case, the zombies' bodies would be completely dead in ten minutes, and it was impossible for them to stand up again, except for some special zombies, of course.

Suddenly, a white light flashed next to him, and Zhang Wei looked at a flaming zombie rushing in front of him in surprise, and was instantly split in half by a white energy sword! Then the rotting body slowly burned into white flames, and finally turned into a pile of ashes, leaving no bones behind! Looking back, Nangong Xue was holding a silver-white long sword in his hand, which emitted a glowing white light, and the energy sword flying outside was controlled by the holy sword in Nangong Xue's hand, and all the zombies that were chopped down turned into a ball of fire and burned to ashes! These mutated zombies are not everyone's opponents at all, if they are placed outside, they can still cause damage to ordinary people, but in the face of everyone who can't get close, they will be killed by the Thunder God Sword in Zhang Wei's hand and Nangong Xue's Flame Holy Sword!

"Damn, how could it be! What are Seven and Five doing! Did you get in touch! Dr. B saw that those zombies were killed without even being able to get close to each other, and angrily slapped the table and shouted, if Seven and Five came back alone, they would be able to get rid of these guys, but Seven hadn't come back yet, and Five and Han Bing had gone out again, and they couldn't be contacted until now!

"Doctor, the outside surveillance screen is connected! Something happened to the seven and five! The person in charge of monitoring hurriedly shouted, switching his screen to the big screen in the center, everyone looked up at the screen in surprise, Seven and Five were fighting in the sky with an old man in a cyan robe, and there seemed to be many people around, when the picture turned to the entrance of the base, Dr. B almost overturned the table, because he saw that the gate of the entrance was violently demolished, and a large number of government mutants were entering! Surrounded by countless soldiers!

"Damn, where did the ice go? Contacted? Dr. B quickly calmed down and asked the liaison officer in charge of liaison.

"Doctor, Assistant Ice's communicator has been turned off and cannot be contacted." The liaison reported.

"Doctor, the entrance to the base outside has been discovered, are we" The person in charge of security said in a combat uniform with an electromagnetic gun pinned to his waist, if he doesn't make a choice, I'm afraid it will be too late to evacuate!

"Open all defenses on floors -3 to -5, release all combat robots, prepare for retreat, copy all data, delete all computer data, and enter the emergency evacuation area except for security personnel and necessary control personnel." Dr. B commanded with a gloomy face, at this time he no longer had the confidence that he just thought he could hold on for a few days, at this rate, in less than two hours, the subject would enter the -6th floor, that is, himself, if he didn't retreat, I'm afraid he wouldn't be able to leave!

"Tell the personnel in charge of the Saint Crystal on the 7th floor to turn on the detonation device and detonate the Saint Crystal after we evacuate! Since you dare to enter the base, don't go back, stay here forever! Dr. B said to his assistant. If that Saint Crystal explodes, I'm afraid the entire Dragon City base will be destroyed! There is no doubt about the power of the Holy Crystal, its energy reserves are estimated to be enough to carry the entire base at full capacity for more than five hundred years! The golden-yellow crystal, full of energy found near the center of the earth, is named the Holy Crystal! However, at first, no matter if the experimenters tested, they could not channel the energy in the holy crystal, and then there was a special accident! An experimenter accidentally in the process of testing the Holy Crystal, the wrong source liquid in the test liquid of the Holy Crystal, after the source liquid poured on the Holy Crystal, the Holy Crystal had a strange change, the internal coagulation energy became soft, and the last experimenter successfully guided the energy in the Holy Crystal, but because the energy was too strong, the experimenter was blown into meat sauce, and then under the research of the entire base, the huge energy converter was created, and the Holy Crystal was placed at the bottom of the base - 7 floors, Serve as an energy source for the entire base! Now that the base is about to be completely breached, if you want to transfer the Saint Crystal, it will take at least ten hours to dismantle and place the Saint Crystal, otherwise it is likely that there will be an explosion due to environmental changes! If the Holy Crystal explodes, the consequences will cause this underground base to be destroyed in an instant! What's more serious is that the safety of the Longdu base is not guaranteed, and there are still millions of people living here!
