Constantly devouring the energy core he received from Guo De's hand, Li Xuan felt the energy of a huge energy in his body slowly melt into his whole body, which was more than many times stronger than the small energy core of the mechanical mouse before.

"It works!" Guo De rubbed his hands excitedly and paced back and forth, this was his last hope. If he can't do it now, then he will be completely poor and have to start from scratch.

At this moment, the rate at which Li Xuan absorbed energy cores, which was visible to the naked eye, had obviously decreased a lot, that is to say, the energy in Li Xuan's body was gradually saturated at this moment.

A pale yellow light slowly rose from Li Xuan's body, and the whole person was like a gold coating.

Guo De's eyes widened, and while he was amazed, his footsteps couldn't help but retreat towards the high platform, now he has no means to balance Li Xuan!

The mechanical core, which was still entering, gradually stopped looking for death, and the reality circled around suspiciously, and then came over to touch Li Xuan's body affectionately.

"Ahh

Li Xuan yelled unconsciously! It's like a lazy waist that sleeps well, or a burp that eats well. Now he is full of comfort power.

"Squeak!"

The cage in front of him, as soon as it changed its previous tenacity, was now deformed in Li Xuan's hands like paper paste.

"Wang Xuan?!" Guo De is strong and calm. "The time is ripe for you to go."

The changes in Li Xuan's body have exceeded the range he expected, and now the energy core has also been depleted. The opponent's powerful combat power is no longer something that he can control.

"Yes! The time is ripe. Li Xuan snorted coldly and walked slowly towards Guo De on the high platform. The threat between the gestures is palpable.

"What do you want to do?" Guo De frowned, his steps retreated slightly, and his hands trembled a little. "What, now that you think you've become stronger, the old man can't sanction you?"

Since it is a base, it is clear that it has a self-destruct device.

"Of course not." Li Xuan paused slightly, although it was a good choice to kill the other party at the moment, but everything here is unknown, if the other party really has the means to deal with him, it will be a bit more than worth the loss.

And with his current silver steel body, it is already a taboo existence, and when the time comes, he may be able to hide here if he rescues his mother.

And with Guo De's talent and means, he may be able to come in handy in the future.

"Where are you going now?" Li Xuan clenched his fists, looking at his body faintly shining with golden light, now let's take a look at the super-large energy core that the other party said.

"Follow me!" Guo De took a deep look at Li Xuan, and led the way in front with a remote control.

Li Xuan glanced at it slightly, and guessed that maybe that was Guo De's means of self-protection now.

"Look!"

The caves in the cliff extend in all directions, and Li Xuan really can't believe that these things in front of him are all done by this old man alone. As Guo De led the way, a relatively bright place gradually appeared in front of him, a rare partition made of glass, and the situation below could be seen completely.

"Hiss......"

Li Xuan couldn't help but gasp. The thing in front of me is like a huge golden heart. Quietly crawling on it was a large mechanical rat. And around the huge yellow heart, there are countless mechanical rats coming and going in an orderly manner.

"What is this?" Li Xuan's eyes widened.

"That's what I'm talking about super-sized energy cores." Guo De's face was full of excitement, "He is the origin of all the mechanical rats in this piece!" ”

"With the gradual mechanization of species, these large mechanical hearts appeared, guarded by the strongest people in the group. The rest is to go out and find metal materials that can be derived. Guo De explained slowly. The running mechanical rats are holding all kinds of metal in their mouths. ”

"As the metal gets close to the giant energy core, it gradually transforms into the form of a new generation of robotic mice."

"The most terrifying thing is that this kind of huge energy core is like silver steel, which can grow on its own!" Guo De licked his lips, "But it's an inexhaustible source of the strongest energy!" ”

Compared with Guo De's excitement, Li Xuan frowned at this moment.

The mechanical giant rat that crawled atop a giant energy core didn't seem to be as mindless as the other mechanical rats. And the small mechanical rats that are slowly forming on it are emerging in endlessly. If it goes on like this, then it's okay.

"The speed of reproduction is too exaggerated!" Li Xuan gritted his teeth.

"No exaggeration!" Waved his hand again and again! "These mechanical rats have to come back regularly to take in energy, and when they reach a certain amount, they will stop reproducing, presumably the huge energy core will also need time to recover, and then the collected metal will be used to strengthen."

"That mechanical rat king is the target of strengthening!" Guo De pursed his lips.

Li Xuan fell into deep thought when he heard this, the orderly reproduction methods of the mechanical mouse seemed to be restricted by some kind of rule. It's like its own silver steel body, and it doesn't seem to be naturally formed.

"Isn't it incredible!" Guo De pulled the hair, "It was incredible when I first saw it. ”

"That's when I just noticed that the mechanical rats here were all walking in an orderly track, and later, I used the device to follow and spy on the approximate location."

"In the end, I guessed the space directly above and used it for observation."

"It's a pity that no matter how much I research, my machine can't get close to the super-large energy core." Guo De shook his head helplessly, "I almost succeeded again, but I was directly torn up by that mechanical beast." ”

The mechanical giant rat is the king of the mechanical rat swarm, and it is also the guardian of the super-large energy core.

"You mean I'm going to fight them anyway?" Li Xuan raised an eyebrow.

"It's not them, it's it!" Guo De said haha, you are just a challenger who is considered a rising star. If you defeat it, you're the new Rata-king.

"Whoa!" Guo De suddenly threw over a pair of gloves.

"What is this?" Li Xuan's face was full of doubts.

"This can help you effectively block your body from absorbing energy nuclei. Now you can't seem to control your body, so in order to avoid any mistakes at that time, you may be able to use it. ”

After all, the super energy possessed by the super-large energy core is beyond the two of them can estimate.

Li Xuan couldn't help but roll his eyes when he heard this, the other party was now sure that he would take the risk with his life.

"Why did you and my father premeditate the theft of the silver steel?" Li Xuan moved his muscles, if he could spy on one or two of the secrets of this super-large energy core, he would figure out his father's thoughts about his life adventure.

After all, a good student has a stable life and a bright future, so why take such a risk.

"Scientific research dream!" Guo De smiled awkwardly, Li Xuan shook his head, if he said that this old man was a scientific research dream, he would believe it, but his father, he was sure that it was not!

Because he loved himself and his mother dearly.

"Where do you go down from?" Li Xuan looked around, he didn't have much time to squander, even if he was strong now, but after all, he didn't know much about the combat power of the mechanical giant rat.

"Follow the path behind you, go straight to the innermost, and then go straight to the end." Guo De was a little impatient, "There is a huge manhole cover there, you can go down by twisting the valve next to it, and go inside, and it shouldn't be long before you reach the nest of the mechanical rat." ”

Li Xuan took a deep look at Guo De, and it seemed that the surroundings of the old nest of the mechanical rat had been clearly touched by the old man in front of him.

"When the time comes, you'll win the mechanical giant rat, and I'll tell you where to take the energy core!" At this moment, Guo De's face is full of courtesy, far from the arrogant appearance at the beginning.

The trail was damp and dark, and apparently as far as Guo De was concerned, it had been a long time.

The rusty manhole cover was shattered by Li Xuan's slight force, Li Xuan turned around helplessly and spread his hands, he was still a little uncomfortable with his current strength.

Guo De twitched the corners of his mouth and waved his hand with a straight face, seemingly not caring. And as soon as Li Xuan went down, he quickly began to look for it, to see if there was any cover that could resist the mechanical rat swarm.

Compared to the damp and dark above, the bottom is much brighter. The light and temperature that came slowly from the depths made Li Xuan can't help but be vigilant.

Even though he is extremely confident in his current body, the fear in his heart is beyond words. The scene of running away from the game with the mechanical rat swarm constantly echoes in my mind.

"Squeak Squeak......"

There were several mechanical rats running around, and Li Xuan knew that this one sewer was connected to the square pit made by Guo De. And he just had to follow these rushing mechanical rats all the way forward.

"What?"

When Li Xuan gradually approached the end, he was shocked by the scene in front of him and was speechless. There is only a small cave in this place, and you can barely see what you can see inside. Presumably, Guo De didn't dare to continue digging when he dug here!

"Boom!"

Li Xuan didn't have so much time to think about it, and opened up a way for himself to move forward with a direct violent kick, and subconsciously wanted to look up at Guo De above, but couldn't help rolling his eyes, it was actually a one-way glass!

The rushing mechanical rat seemed to feel the sensation, and gradually stopped its busy pace, staring at Li Xuan suspiciously.

The huge golden and dazzling energy core looks even more spectacular than it looks on it. Feeling the heat coming from his face, Li Xuan clenched his fists in a deep voice, facing the mechanical giant rat lying on top of the energy core, staring at him.

"Squeak Squeak......"

With a low and authoritative sound, the mechanical rats around them became busy again, as if Li Xuan did not exist.

"Sure enough, there is wisdom!" Li Xuan pursed his lips, presumably this huge energy core should be an important reason for the transformation of mechanical mice.

"Bang!"

The mechanical giant rat that jumped down was far bigger than he imagined, Li Xuan took a deep breath, and now, it seemed that he could only face it!
