"Roar ......" the Black Dragon King raised his head to the sky and roared, and then pounced on the two of them under the manipulation of the Black Dragon Doctor.

"No way, let's fight!" Chen Xi yelled, and then took Fei Kun to meet him.

"Yan Emperor Red Dragon Jue!" Chen Xi took the lead in using his ultimate, and the two flame dragons shot out at the same time, shooting straight towards the iron-armored black dragon king.

"......Boom" Two clouds of fire exploded on the body of the Black Dragon King in an instant, but this indestructible move only left two shallow black marks on the dragon's body.

At this time, the fat man's fire snake heavy machine gun had already begun to roar, and hundreds of bullets were raining down on the dragon.

However, like raindrops hitting a steel plate, hundreds of bullets did not even hurt the Black Dragon King's fur. Fei Kun still deliberately aimed the machine gun at the position of the black dragon king's muscle tissue, but those bullets were shallowly embedded in the dragon's epidermis, and it was difficult to enter half a minute, and then the epidermal tissue squirmed slightly, and one bullet after another fell down with a clang.

I'll go, how can this still be fought! All attacks are ineffective against the enemy. Chen Xi and Fei Kun were dumbfounded.

"Hahaha......" Dr. Black Dragon's voice suddenly came from the dragon's mouth, "My iron-armored Black Dragon King is invincible, you two small worms, obediently suffer death!" As he spoke, the dragon roared violently, and hundreds of laser cannons were immediately revealed all over his body, and for a moment, volleyball-sized laser bullets suddenly fell from the sky like hailstones.

At the same time, the dragon raised its heavy truck-like feet and stomped on the two of them. Don't look at the big guy's huge and bulky body, he has been moving slowly just now, but at this moment he is really fast as the wind, and his big feet fall suddenly, forcing the two of them to jump wildly to dodge, and from time to time they are brushed by laser projectiles, or hit by the flying debris falling from their big feet. No wonder the fat man said that he was trampled to death by Bigfoot last time, and if he continued like this, he was either trampled to death or killed by a laser projectile.

No, the system will never design a level that is impossible to pass, there must be a way. Chen Xi dodged the laser projectiles and the dragon's feet in the sky, and his brain was racing rapidly.

What is the weakness of this big guy?

Pregnant! Chen Xi suddenly had an idea, and shouted loudly: "Fatty, let's run to the factory, it's more convenient for us to dodge when we enter the factory!" With that, he sped towards the huge arsenal on the shores of the lava lake.

Fei Kun agreed, immediately drove the mecha, and quickly fled to the factory.

"Cunning bugs, I've had enough, it's time to get rid of you!" Dr. Black Dragon screamed, and dozens of small holes opened on the Black Dragon King's body again, and then dozens of small missiles shot towards the two of them like a crazy swarm.

In an instant, the two of them were locked by the missiles that covered the sky, and they were about to be buried under the indiscriminate bombardment, the fat man turned back suddenly, opened the electromagnetic shield suddenly, the maximum power output, and then shouted: "Chen Xi run!" ”

In the next second, several missiles exploded on the electromagnetic shield, tearing the electromagnetic shield to shreds like a layer of tissue paper almost instantly. Then more than a dozen missiles roared and immediately engulfed the fat man.

"Fei Kun ......" Chen Xi turned his head and roared, gritted his teeth and continued to rush forward, but was blocked by Fei Kun so sacrificed, and the remaining missiles suddenly missed, and Chen Xi escaped with his life.

The distance of the lava lake was only a few kilometers, and with the speed at which Chen Xi manipulated the role of Li Jielong, a kung fu man, it was faster than a flying arrow, and it ran to the factory area in just a few minutes. Dr. Black Dragon manipulated the iron-clad Black Dragon King to chase after him in an instant. But Chen Xi had already burrowed into the gaps of dense factories and machinery like a fish.

"Nasty rat!" Dr. Black Dragon scolded again, he didn't seem to want to destroy the factory too much, so he manipulated the Black Dragon King to circle around the factory, and at the same time suddenly opened three hatches from the Black Dragon King, releasing three biological mechanical velociraptors.

Three velociraptors rushed into the factory like hunting dogs, frantically searching for Chen Xi who was hiding.

For this kind of natural hunter with a genetically modified nose equipped with an infrared electronic eye to enhance the sense of smell, general concealment is ineffective. Not long after, Chen Xi, who was hiding behind a pile of metal plates, was forced out by the velociraptor rex.

Chen Xi slashed out a white crane palm to repel the velociraptor that first found him, and at the same time fled in a hurry, he leaped and soared, but the three velociraptors were screaming and running wildly, chasing after him.

Suddenly, Chen Xifei jumped up, but he turned around in mid-air, and there was already a huge golden pistol in his hand.

With a roar of "bang", the overlord's super attack was already shooting, piercing the head of the first velociraptor in the first place. Then he fell to the ground and ran away.

The remaining two velociraptors were immediately furious, and when they opened their mouths, they shot two laser light bullets, one of which passed by Chen Xi, and the other shot hit Chen Xi's back. Immediately, Chen Xi was blown out and smashed into the wall of a factory.

The two velociraptors immediately pounced, but as soon as they approached the factory, an electromagnetic grenade had been thrown out of the hole that Chen Xi had hit. In an instant, it exploded in the middle of the two velociraptors, and the fire and the arc immediately reflected each other, and the electronic components of the two velociraptors were immediately disturbed and began to be chaotic.

Taking advantage of this opportunity, Chen Xi had already jumped out like a ghost, and a tiger roar hit the head of one of the velociraptors, followed by the deception, and a bear slammed into its chest. Immediately killed the velociraptor , at the same time he took out the overlord gun, aimed at the other velociraptor and pulled the trigger, nine pistol bullets shot at its head, and then he kicked the last velociraptor to death.

"Haha......" Dr. Black Dragon laughed angrily, "Well, you've done a great job, but it has made me more able to check that my weapons are not well studied." Now, try this again. Before he could finish speaking, the black dragon king opened the hatch again, releasing three velociraptors, as well as two half-machine, half-biological pterosaurs.

The five evil dragons immediately rushed towards the factory, especially the two pterosaurs, spread their wide membranous wings, soaring in the air, aiming at Chen Xi who was fleeing around on the ground from time to time, opening their big mouths and shooting out a laser light.

This is really a desperate situation, the five evil dragons are pressing forward step by step, and soon Chen Xi is forced to cross the entire factory area and escape to the edge of the lava lake, and at this time, Dr. Black Dragon has already manipulated the dragon to bypass the factory area and run to the lava lake. is intercepting Chen Xi from the side.

"Now I'll see how you're still running!" Dr. Black Dragon sneered, and immediately shot dozens of laser light cannons from the Black Dragon King's body.

Chen Xi's body was in a hurry, like a swift passing through a storm, dodging dense laser light bullets, and finally was hit by a light bullet, and the whole person flew out like a broken kite, and landed directly on the edge of the lava lake, only less than two meters, about to fall into the lava.

Chen Xidan felt that his bones were about to crack, and his eyes turned black for a while. His level is much higher than that of the fat man, and the negative feelings are weakened a lot, and at the moment it is really painful, lying there unable to even move a finger, he struggles to scan his blood volume, and there is less than 5% left.

"Hehe, accept your fate, suffer death!" Dr. Black Dragon laughed wildly and manipulated the dragon to take a step, then raised his huge claws, and stepped on Chen Xi with his head covered.

"It's now!" Chen Xi suddenly roared, jumped up at the last moment, flashed the dragon's big foot trampling, and then slammed his fist on the ground.

It is the ultimate skill "Xuanyuan Yellow Dragon Jue!" ”

In an instant, the ground cracked, and two rolling yellow dragons surrounded the Black Dragon King and stirred it to pieces.

Soon, raging magma erupted from cracks in the ground, and the entire ground cracked open and collapsed into the lava lake.

The Black Dragon King's huge body accelerated the collapse of the ground, and in an instant, the Black Dragon King was unsteady on his feet, and he had already stepped into the lava.

That's right, this is Chen Xi's tactic to introduce Dr. Black Dragon into the lava lake. From the initial escape to the factory area to the later fall on the shore of the lava lake, it was all designed for this tactical purpose. Especially at the last moment, when he fell on the shore of the lava lake, he was gambling that Dr. Black Dragon would step forward and trample him to death with a dragon's foot, instead of covering him with a laser cannon or missile from a distance.

If it's the latter, then everything is over, but if it's the former, it might be able to lure Dr. Black Dragon to the edge of the lava lake. But he's not shit luck either, he's at least eighty percent sure that Dr. Black Dragon will come up and step on that kick.

Because the fat man said that he was also trampled to death last time; And at the beginning of this battle at the bottom of the pass, Dr. Black Dragon also stepped on it with his feet; also because he fell near the Black Dragon King, like a bug lying on the ground near a person, if he wants to kill this bug, the reaction of ordinary people must be to go up and kick it, even if it is common sense, this is more direct, more convenient, and more enjoyable!

Therefore, Chen Xi was right, and Dr. Heilong was going to be unlucky.

"Damn! You cunning bug! Dr. Black Dragon let out a frightened roar, he desperately manipulated the Iron Armored Black Dragon King to escape to the shore, but how could Chen Xi give him this opportunity.

At this time, Chen Xi had already jumped onto the lap of the Black Dragon King, he grabbed a steel cone tightly with one hand, and immediately threw all the grenades on his body, whether electromagnetic or high-explosive, under the leg where the Black Dragon King was still standing on the ground.

The chain explosion immediately shook the Black Dragon King again, and this time not only failed to pull out the foot that had fallen into the lava, but the other foot also fell into the lava lake.

"Bastard......" Dr. Black Dragon struggled to manipulate the Black Dragon King to grab Chen Xi on his leg with a wave of his claws, and at the same time, the laser cannon on his body shot together, seeing that Chen Xi was about to die under the claw light cannon......

At this time, Chen Xi had already swallowed the last full recovery potion, and then kicked the dragon's thigh with his right foot, and the body was already flying out like an arrow from the string.

In mid-air, he twisted his waist suddenly, and saw a large piece of laser light bombs whistling in, but he sneered slightly, and there was already an extra thing in his hand, which was the sonic annihilation cannon dropped by the Tyrannosaurus rex Agang,

In an instant, the sonic cannon was launched, and a swirling sound wave was emitted, instantly annihilating a large laser projectile. At the same time, this weapon, which could only be used once, was also casually discarded by Chen Xi.

"I'll give you another ride!" Chen Xi roared angrily, his hands were already full of red flames, and two flame dragons instantly poured out of his palms, attacking the Black Dragon King one after the other.

"No......" Dr. Black Dragon let out a desperate scream, and the Black Dragon King, who was already crumbling in the lava lake but still struggling, was hit by two red dragons the next moment, could no longer support it, and fell into the rolling magma tiltingly.

Like a lump of cheese falling into a boiling soup pot, Dr. Black Dragon, the pride of his life, the Iron Armored Black Dragon King, the strongest living mechanical weapon, struggled and fluttered in the magma lake, but he never got up again, and was completely swallowed by the magma in a short time.

Chen Xi lay down next to the magma lake, his body was sore, and he could barely move, with a triumphant smile on his face, he muttered, "Fatty, I have avenged you!" ”

After a while, he got up and walked to the lava lake, where he saw a golden suitcase, four silver suitcases, and six black iron chests scattered around the edge of the lake, shining brightly.

Chen Xi hurriedly went up and took the lead in opening the gold chest, and the treasures inside immediately made Chen Xile bloom.

"Fragments of Mysterious Metal (2/9) - Mysterious metal fragments excavated by Karp Corporation from the ruins of ancient alien civilizations, with mysterious supernatural energy on them, and collecting all nine fragments will form the highest technological crystallization of ancient alien civilizations."

The four silver chests are decent, with small boxes of gold bars, skill boosting power crystals, genetically enhanced potions, and advanced ammo supply packs.

The remaining black boxes were even more ordinary, and after packing up all the props, there was only a flower in front of him, and Chen Xi had returned to the base of the underground resistance organization.
