Under the frequency of thought waves, Gu Shuang could see those energy flow trajectories that were invisible to the naked eye.

At this moment, Gu Shuang's thinking wave swept the meteorite above his head, and he found that there was a black energy flow under the meteorite, forming a straight line, falling straight on the palm of his right hand, and then being easily inhaled by the mass core of his right hand.

"What's going on?"

Gu Shuang was stunned

"Why can the mass core draw a stream of energy from the meteorite?"

"Why is there energy in this meteorite?"

At this moment, Gu Shuang felt that his head was not enough, and suddenly, Gu Shuang's head flashed and he thought of a possibility.

"I heard that the steel clan will hide in these meteorites when they are dormant, can it be that they have long known that these meteorites contain majestic energy? Can you warm yourself? ”

Gu Shuang was a little incredulous, but when he recalled that he had just found the mass core, he had to believe it, because the mass core was discovered in the meteorite at that time.

At this moment, Gu Shuang had a guess in his heart.

"Could it be that these meteorites are like those legendary spirit stones? It's all an aggregate of energy??? It's just that no one has found out before? ”

Gu Shuang frowned, thought about it, Gu Shuang tried to move, and after withdrawing the black substance that his left hand was protecting him, he put his left hand on the meteorite.

He was going to try to rely on his own body power to see if he could get some energy from the meteorite, and right now, the Yuan Wheel that he had awakened could rely on the Yuan Wheel to absorb all kinds of energy in the air.

When Gu Shuang's left hand was attached to the meteorite, his mind moved, at this moment, Gu Shuang, who had closed his eyes, opened his eyes violently!

He felt that a harmless energy was sucked into his body from the meteorite, and then refined by the Yuan Wheel and turned into pure Yuan Energy, which made his physique instantly increase by a small section!

"I can really ???"

Gu Shuang looked at his body in astonishment, just now he just absorbed a trace of energy from the meteorite.

But after this trace of energy was refined into Yuan Energy and strengthened his body cells, Gu Shuang found that his strength had increased from thirty-one meters per second to forty meters per second in an instant! Just a little bit away, he can break through to the D rank, enter the C rank, and become a real monster-level existence!

What a terrifying thing this is, Gu Shuang felt his scalp tingle when he looked at the meteorite above his head at the moment!

"I see! I know! I know why those monsters have become so powerful in just sixteen years! It's become so scary! It must be the cause of this meteorite! It must be the cause of this meteorite! ”

Gu Shuang looked at the meteorite above his head with some horror, and his brain fell into confusion in a short moment.

In the next second, Gu Shuang was like crazy, with a look of ecstasy, and put his palm on the meteorite!

"Harmless energy! The energy contained in the meteorite is actually harmless energy! This, this, this! I'm developed! I'm developed! ”

With a crazy smile, Gu Shuang put his right hand on the meteorite, and then began to desperately urge the Yuan Wheel to suck in the energy contained in the meteorite.

Suddenly, a stream of energy as thin as a hair was channeled out of the meteorite, and then inhaled into Gu Shuang's body, after being inhaled into Gu Shuang's body, the heart pumped, and those black energies seemed to have been stripped of their shells, turning into pure white energy, and began to flow between the cells in Gu Shuang's body.

At this moment, Gu Shuang's right hand uses the mass core, and his left hand uses the energy of the Yuan Wheel in the meteorite, the energy flow on his right hand is the size of two fingers, while the energy flow in his left hand is only the size of a hair, but for Gu Shuang, the energy flow the size of a hair is enough for him.

About half an hour later, Gu Shuang opened his eyes and no longer absorbed the energy in the meteorite.

At this moment, his strength has passed the peak of the D-class monster realm, entered the threshold of the C-class monster, and within half an hour, he has reached the level of 99.9 meters per second!

At this point, Gu Shuang felt that he had encountered a limit, and it was difficult to break the peak shackles of C-level monsters and enter the threshold of B-level strong monsters.

"I'm just one step away from getting into B-class! This, this! The energy in this meteorite is terrifying! If the mutants discovered this secret, how could they not be stronger? ”

Gu Shuang was horrified in his heart, and then said firmly: "Those monsters must have discovered the secret in the meteorite!" And because our humans were trapped underground, plus the incident of passing through the steel clan ten years ago, they turned a blind eye to the meteorites on the ground, so they have not been able to discover the secrets in the meteorite! ”

At this moment, Gu Shuang suddenly found that the energy flow on the mass core of his right hand had become smaller, although Gu Shuang's body no longer absorbed the energy in the meteorite, but the mass core had been absorbing, but at this moment, Gu Shuang found that the energy flow drawn by the mass core from the meteorite had changed from the initial size of two fingers, to the end, it was only the size of a hair, and then it disappeared directly!

"Is the energy contained in the meteorite absorbed?"

Gu Shuang gritted his teeth and checked the energy contained in the mass core, and at this time, the energy contained in the mass core had recovered to the point of the eighth layer.

After checking the mass core, Gu Shuang raised his head again and looked at the meteorite above his head, the meteorite did not change anything, only its body color, which had transformed from the original black of the deep space of the universe to the color of ordinary black stone.

Seeing this, Gu Shuang was slightly stunned, this little color change, if you don't look carefully, it is difficult to distinguish.

"It seems that not all meteorites contain energy, only this 'black meteorite' contains energy, and the purity and content of the energy may vary. That's why it helped me get past the D-class and reach the C-level in half an hour! ”

Thinking of this, Gu Shuang's mind moved, quietly moved the meteorite at the entrance of the cave, and flashed out of the cave with the big magic knife.

He's going to check it out.

At present, the place where Gu Shuang is located is called the Great Wilderness Plain, which used to be a lush primeval forest, but later a meteorite came and a disaster occurred, and it became a wasteland.

There were many meteorites in the wasteland, and after Gu Shuang re-blocked the entrance to the cave, he cautiously began to look for black meteorites, preparing to confirm his guess.

But after Gu Shuang searched around, Gu Shuang only found a black meteorite that was not too black in color.

"It is estimated that even if there is energy in this black meteorite, there will not be much!"

After thinking about it, Gu Shuang's right hand was spread out and printed directly on it.

Gu Shuang's guess was right, this black meteorite with a less pure color did contain energy, but because the black one was not too pure, unlike the top-grade black meteorite that Gu Shuang had absorbed earlier, the energy, content, and purity in it were all one grade lower, which only helped Gu Shuang's mass core to restore half of the energy.

At present, the energy contained in the mass core has been restored to eighty and a half, and it is only one and a half percent away from being completely restored.

"It seems that the black meteorite I absorbed earlier is really the best!"

Gu Shuang looked around again and found a black meteorite that was not too black in color again, but the previous black meteorite was not found again, Gu Shuang was slightly disappointed.

But it's not bad, after all, the best black meteorite is not something that can be found if you want to find it, you can only look at luck, thinking of this, Gu Shuang's mind moved, and after absorbing the 'miscellaneous' black meteorite in front of him with the mass core, the energy in the mass core was restored to ninety percent.

"I don't know where these black meteorites with energy come from?"

Gu Shuang was puzzled, and suddenly he arrived at what Yuan Tiangang of the steel clan had said to him.

"We're here to be beaten..."

"Looks like there's a big secret here!" Gu Shuang thought for a while, and after putting aside these things that he couldn't figure out for the time being, Gu Shuang was ready to return to the cave, right now, Sun Li and Zheng Qing were still in the cave, in case they encountered any danger, it would be difficult to do.

But at this moment, Gu Shuang seemed to feel something, his feet paused, and then he turned his head sharply and looked at the end of the horizon.

At the end of the horizon, a creature with a pug's head is lying on the ground sniffing! Behind him is a Mr. Cat with a sword and looking around, and a tall lizardman!

"Did you find it so soon?"

After Gu Shuang relaxed his muscles, he slowly squatted down, and as soon as he drilled the ground with his toes, the ground was like mud, and it was directly drilled away, and then Gu Shuang's whole person was like a ghost, and he fell directly into the ground!

"I hope you can just leave!"

In the underground, Gu Shuang slowly pulled out the Great Demon Knife, and then waited patiently.

In the distance, the pug man with the nervous Mr. Cat and the tall lizard man had already looked for Gu Shuang step by step.

"Pug, there is no breath of Gu Shuang, the number one human master here, right?"

Mr. Cat asked nervously, his eyes scanning the surroundings.

Gu Shuang was shocked when he saw this, if he hadn't just dived into the ground first, it was estimated that he would have been discovered by Mr. Cat at this time.

When the pug man heard Mr. Cat's words, he sniffed the ground and said, "Boss, here is the breath of Gu Shuang, the number one human master!" ”

"What!?"

Mr. Cat was startled, and then recalled the scene where Gu Shuang killed the horse-headed man and the little bull-headed man with one sword, and his face instantly turned pale!

"Since there is, let's go back and report it to the ape-sama!"

Mr. Cat said tremblingly, the ape led people to search in another direction at this time, he scattered his subordinates, and looked for Gu Shuang's traces in a group of three, Xue Shan'e's people were also there, but Xue Shan'e himself returned to Ukiyo Mountain, thinking that he was worried about his queen.

When the lizardman heard Mr. Cat's words, he snorted and pushed Mr. Cat impatiently.

"Look at you cowardly! That Gu Shuang only has S-level strength! He killed the demon beast Li Yuanjun is also a trick, you must know that I have the strength of the peak of the S-level! Just find him, you two stand aside and hand him over to me!" ”

After speaking, the lizardman glanced around coldly, and the terrifying lizard tongue was like a poisonous snake in the dark night, flashing with a cold-blooded breath!

"Pug people! Find out! ”

The lizardman glared down at the pug man who looked up, and raised his shimmering lizard claws, and the pug man replied in a panic when he saw this, and then fell on the ground and began to sniff wildly.

Underground, Gu Shuang looked at the sniffing pug man, frowned, and then looked up at the lizardman who was following the pug.

"S-class pinnacle? .... Hum! ”

Underground, Gu Shuang held the Great Demon Knife hard, and in an instant, the body of the Great Demon Knife became extremely red!

"As long as you come, I want you to die!"

Looking at the three people who were getting closer and closer, a bloody light flashed in Gu Shuang's eyes, and then gradually became cold-blooded and ruthless!
