The mechanical rat king stared at the provocateur who suddenly appeared in front of him, pacing slowly, and the two lights under his head seemed to be full of banter.

Although the energy power in Li Xuan's body is strong, it is much inferior to the mechanical rat king.

"What the hell is this mechanical rat king?" Li Xuan frowned, if he said that the other party was just an emotionless fighting machine, but this performance was full of his own unique thinking. If the other party is a living being, the bare mechanical skeleton has been baptized by a super-large energy core, and all the characteristics of living things have long been abandoned.

"Just destroy the other party's energy core!" Looking at the energy core at the other party's heart, Li Xuan clenched his fists and nodded in a deep voice, if it was one-on-one, with his current strength, he should be able to deal with it.

"Squeak!"

The mechanical rat king looked at Li Xuan's movements, and seemed to be greatly provoked, and rushed over with an uncomfortable sound.

The seemingly slender mechanical rat leg erupted with powerful energy at this moment, and while it struck quickly, it left an indelible footprint in this path.

The mechanical rats, who were still busy on the side, also dropped the metal in their mouths and curled up in the corner, motionless.

Compared with those fragmentary mechanical rats, the mechanical rat king not only has extremely explosive power, but also has sharp fangs and claws. It seems to have been created specifically for fighting.

Li Xuan silently resisted the attack of the mechanical rat king, and with his current style, he would not be suppressed by a mechanical mouse.

And just when Li Xuan was trying his best to deal with the claws and fangs of the Rat King, ready to find an opportunity to launch a surprise attack on the opponent's energy core, the rat tail that swayed from nowhere was like a long whip, hitting Li Xuan's abdomen hard.

"Ding......

"Boom ......"

The strength of the rat's tail was like a thousand pounds, knocking Li Xuan out of the air. And that crisp sound was naturally emitted by Li Xuan's body that exuded golden light.

If you say that you were a silver steel body before, then your body full of energy now is a golden body!

Li Xuan grinned and got up, except for the slight pain, there was no substantial injury. It's just that the golden light on his body has dimmed slightly.

"What's going on?" Li Xuan's eyes couldn't help but widen, looking at his arm, could it be that the accumulated energy core will be gradually consumed?

"Gotta hurry!" Now it seems that the energy absorbed by oneself is obviously not infinitely used, as oneself fights and consumes, the energy obtained from the energy core is also constantly decreasing, when it is reduced to a certain amount, presumably these nearby mechanical rats will attack themselves in groups!

The mechanical rat king, who succeeded in the first blow, did not take advantage of the victory to pursue, but ran back to the vicinity of the super-large energy core and jumped on it.

"Oops!"

"It's refueling!"

In the process of continuous consumption of energy in Li Xuan's body, the mechanical rat king obviously also consumed a lot, just like Guo De's mechanical warrior!

And at this moment, the mechanical rat king is replenishing the energy consumed, and the energy core, which was originally a little dim, flashes with dazzling light again in an instant!

What a tough opponent!

Li Xuan gritted his teeth, his own energy was constantly being consumed, but the other party's energy was inexhaustible! Although his combat power is not lost to the other side, if it goes on like this, it will be a dead end!

Guo De, who was watching above, couldn't help but stomp his feet when he saw this, he didn't expect that the mechanical rat king could replenish energy while fighting, if this continued, when the energy in Li Xuan's body was not enough to pretend to be a mechanical mouse, it would be Li Xuan's death!

Guo De really wanted to help, he naturally didn't want Li Xuan to fail, but his mechanical warriors no longer had energy cores to use.

Pregnant! Guo De, who was in a panic, suddenly brightened his eyes, as long as this mechanical rat king couldn't replenish energy, then Li Xuan would have a big chance!

"Squeak ......"

The mechanical rat that had replenished the energy didn't seem to intend to give Li Xuan a chance to breathe, so he rushed up with a strange scream.

Li Xuan gritted his teeth and retreated while fighting, thinking about the strategy to deal with it, and at the same time beware of the elusive rat tail! There is no chance of winning this battle at all!

"Wang Xuan, lead him to the entrance!" Guo De's voice suddenly came from the sewer beside him, Li Xuan was shocked when he heard this, and then he didn't think much about it, so he moved in the direction indicated by Guo De, after all, Guo De here is far more familiar than himself.

The more Li Xuan retreated, the more fierce the Rat King's offensive became. seems to uphold the principle of taking advantage of your illness to kill you, and constantly suppress it. The corners of Li Xuan's mouth tilted, a mechanical beast is a mechanical beast, and he is afraid that the other party will not follow!

"Be careful!"

"Boom!"

As Guo De shouted, the tunnel trembled. The overwhelming rubble entangled the rat king behind him and smashed it over.

Li Xuan couldn't help but shudder, and after a few jumps and rolls, he got out of the range of the attack, I have to say that this Guo De is still the same age as him, frizzy. The Rat King, on the other hand, used the rat's tail to catapult a few times between the rock walls, and also got out of the attack range of the gravel.

This was originally Guo De's back-hand method to guard against mechanical mice, but it didn't arrive first, and it actually came in handy at this moment.

"Now!" Guo De shouted at Li Xuan at the manhole cover, "Hurry up and deal with him while the mechanical rat swarm has not broken through this piece of ruin!" ”

Guo De poked his head, his eyes were a little flustered, you must know that the big manhole cover on it had been damaged by Li Xuan, whether it was the mechanical rat king or the mechanical rat group, it was impossible for the old man with weak combat strength to parry.

"Good!" Li Xuan nodded heavily, he was not naïve enough to think that a mere explosion could solve this mechanical rat king.

The mechanical rat king's humanity looked back at the blocked retreat, and suddenly let out a strange scream, and then there was a chattering sound from the other side of the ruins.

"Now is not the time to hesitate!"

Li Xuan shouted, and rushed towards the mechanical rat king, with the cover of gravel, but he provided Li Xuan with a lot of help. After a few struggles, although the energy in his body was almost exhausted, the energy core of this mechanical rat king also dimmed at a speed visible to the naked eye.

The speed and strength of both are rapidly decaying, but compared with the Rat King, Li Xuan's dependence on energy is not as heavy as imagined.

"Boom ......"

Behind him, there was a constant cacophony of chirping, accompanied by the roar of falling rubble. It seems that the wall of ruins will not last long.

"Wang Xuan, hurry up, the mechanical rat swarm is about to rush over!" Guo De was so anxious that he glared, the current Li Xuan had to deal with the mechanical rat king as soon as possible and escape, otherwise, he would be devoured by the mechanical rat swarm when his mechanical rat breath was exhausted.

"Die!"

Li Xuan's eyes tightened, one hand grabbed the fangs that the rat king had bitten, let the other party's claws pierce into his body, and the other hand slammed into the rat king's energy core, grasping the glittering energy core. There's no time to hesitate, even if it's for his life, he has to fight!

"Come on!"

"Squeak Squeak ......"

Just when Guo Desheng was hoarse, the overwhelming mechanical rats poured out, and the gravel blocking the aisle had been eaten up. Li Xuan and the mechanical rat king were instantly submerged in the swarm of rats.

"Hey!" Guo De pounded heavily on the iron plate that was temporarily used to cover the exit. That's just a little bit! If Li Xuan can escape, within three days, they will be able to obtain energy cores when the next rat king is born.

What a pity! Guo De gritted his teeth and sighed heavily. I didn't expect to pay so much, and I was about to succeed, but it was still a failure.

"Li Xuan?!"

And just when he was depressed and wanted to glance at the super-large energy core, Guo De couldn't help but wipe his eyes, and the person standing in front of the energy core at this moment was not Li Xuan, who had just drowned in the mechanical rat group?

"Grandpa Guo, you closed the exit, how can I help you take the energy core out?" Li Xuan looked at the top of his head, smiling rather than smiling.

The moment the mechanical rat swarm was covered, Li Xuan also felt that he was about to finish the game, but it seemed that the energy core of the mechanical rat king was absorbed by himself, and instead of attacking him, this group of mechanical rats hid far away.

Looking at the super-large energy core that was close in front of him at this moment, Li Xuan's eyes couldn't help but widen, and the energy contained in it seemed to be overflowing. Li Xuan couldn't help but be speechless, according to the acquisition standards of energy cores, this Xie Dong didn't know how much money he could sell!

"Put on your gloves, pick him up, and walk in the direction you came and went, where there is a stone gate at your right hand in the deepest part of the place." Guo De opened his mouth tremblingly, Li Xuan really succeeded.

Li Xuan raised his eyebrows, what kind of cliff did this Guo De make? There are footprints everywhere!

"Boom!"

Li Xuan hugged and kicked the stone gate in Guo De's mouth, although it was isolated by gloves, the strong energy still invaded Li Xuan's body from all directions.

What caught the eye in the stone chamber was a huge mechanical claw! Guo De stood on it with a smile on his face. The half-spiral resembles a ceiling, and the circle in the middle seems to be the size of the energy core.

"I didn't expect you to even have this ready." Li Xuan smiled bitterly.

Some people are either chasing their dreams or on their way. Guo De's willingness to spend twenty years here is enough to see where his courage lies!

The energy core in his hand was embedded like a huge mechanical claw, and the dense mechanical mice that came with him curled up in the corners around him.

Guo De manipulated the mechanical giant claw to block the energy core in the circle on top. The protruding part is for Guo De's research, and the large area of energy cores below will be used by mechanical rats as always.

Li Xuan clapped his hands and looked around. "I can go!" If he stayed, he didn't know if he would be besieged by these mechanical rats again.

"Yes, yes!" Guo De turned into a licking dog, full of enthusiasm for Li Xuan.

"If this continues, they will still have a new mechanical rat king." After Li Xuan came out, as the plane fell, the energy core gradually approached the ground level. Li Xuan looked at the group of mechanical rats below that had started to be busy again, and spoke in a deep voice.

"It doesn't matter, as long as it doesn't matter my research!" Looking at the small semi-energy nucleus exposed on it, Guo De's face was full of satisfaction. I believe that by then, he will be able to deal with the new mechanical rat king.
