Since Gu Shuang returned to the base, everything seemed to have become leisurely.

At this time, it was already the tenth day that Gu Shuang had returned to the base, and during these ten days, he accompanied his sister and Ling Hurong to chat during the day, or to meet his friends and teammates, or to go to Chen Zong's place to talk about martial arts, absorb knowledge, or walk around to relax, and at night, Gu Shuang would go to the Eastern Federation Energy Control Room and hide in it to practice.

Life can be described as very leisurely.

On the side of the plant species, Situ Nan had already arranged for someone to go back to report the news, as for what happened, Gu Shuang and they were not very clear, but Gu Shuangchai at this time Lu Yiluo and Ku Sensuo were fighting wits and methods, and for a while, there may not be results, although there are no results yet, but according to the analysis of the think tank, there are nothing more than two kinds, one, Ku Sensuo successfully took away a group of people, and second, Ku Sensuo failed, and was even killed by Lu Yiluo.

The person who Situ Nan arranged to go to the plant plant to report to Lu Yiluo was none other than the log hibiscus, this kid Gu Shuang took the time to meet him when he came back, and found that he had changed his appearance greatly, wearing a white dress, with a straight waist, holding a Confucian holy book in his hand, there was actually a sense of righteousness, even when he saw Gu Shuang, the enemy who beat him into a pig's head in the past, he smiled faintly, indicating that he didn't care, and even treated Gu Shuang as a guest, showing a superhuman gentleman's demeanor, which made Gu Shuang look surprised. I want to find out what kind of ecstasy soup Situ Nan poured into him.

It's a pity that Situ Nan just said lightly: "It's just a few words from the heart", so that after Gu Shuang heard it, he seemed to understand whether he understood or not, and he was in a fog.

After seeing the hibiscus, Gu Shuang took the time to look at the twelve teenagers and girls of the plant species, he had not yet fully integrated into human life, but Gu Shuang was not anxious, because these were all water grinding work, so he could only take his time.

Right now, Gu Shuang only has one thing to worry about at this time, that is, Gu Shuang found that his ontology cultivation speed was stuck, and when he hadn't returned to the base, Gu Shuang absorbed the energy in a piece of top-grade black meteorite, and raised his ontology strength to the peak of C-level, to the point of ninety-nine meters per second.

But now, Gu Shuang cultivated again, and found that he seemed to be trapped in a shackle, his cells seemed to have been strengthened to a limit by the yuan energy, and the yuan energy in his body had reached a saturated state, which was difficult to improve.

Originally, Gu Shuang also wanted to try to promote the cultivation system of the Yuan Wheel and let the entire Eastern Federation be blessed, but now Gu Shuang seems that if he doesn't solve this problem, he may not think about promoting, once it is promoted, the people of the Eastern Federation will have a problem with their practice, and they will not be able to save it.

For this reason, Gu Shuang quietly used the name of 'examination school' to inquire about the twelve plant-species teenagers and girls who are currently being educated in the highest university in the Eastern Federation, they all have B-level strength, but unfortunately, they don't seem to have any bottlenecks, this is probably because they have mutated, cultivation only needs to absorb energy desperately, it is extremely simple, and it is rude and unreasonable.

Knowing this, Gu Shuang felt more wary of the mutants.

You can absorb energy unscrupulously, and there is a 'black meteorite' on the ground that contains high-purity energy, and it is also a treasure that can be seen everywhere, never worrying about bottlenecks, such a group of monsters, how can the cultivation speed not be terrifying? With such a fast cultivation speed, how could their strength not become extremely strong?

Thinking about it, after Gu Shuang refilled the energy of the mass core, he decided to go to his senior brother Chen Zong to take a look, before, Chen Zong's strength was not obtained in one step, he also went through penance, so Gu Shuang wanted to see if he could get any inspiration from him.

After Chen Zong saw Gu Shuanglai, he pulled Gu Shuang to learn without saying a word, after taking the X medicine, Chen Zong's strength increased, but unfortunately he did not awaken the Yuan Wheel, so he still couldn't cultivate, and his strength was almost constant, and at present, Gu Shuang had not perfected a set of cultivation methods suitable for human beings, so Chen Zong's strength would not increase for a period of time, and after Gu Shuang summed up a set of methods suitable for human cultivation, Chen Zong's strength might increase significantly if nothing else.

When the time comes, my senior brother will probably become the second human powerhouse below me.

After some discussion, Chen Zong took the lead in exhausting his physical strength, and then sat on the steps and chatted with Gu Shuang.

Chen Zong first talked about Gu Shuang's sword technique, and he commented that Gu Shuang has now entered the first realm of knife technique, shape, and the next realm, he will step into, God, the god of his skills, and after this realm, he will step into the legendary realm of sword intent.

"Life and death fighting is the best place to hone your sword skills, junior brother, it seems that you have experienced a hard battle outside!"

Chen Zong looked at Gu Shuang with a smile, and Gu Shuang nodded silently when he saw this: "It's a fight that has been experienced..."

Gu Shuang didn't go into detail about those things, but paused, went straight to the point, and said to Chen Zong: "I have recently found a path suitable for human cultivation, but now that my junior brother has encountered a bottleneck, I came today to ask my senior brother, hoping to get a little inspiration from my senior brother!" ”

"Oh?"

When Chen Zong heard this, he was slightly surprised: "A path suitable for human cultivation? ”

Gu Shuang nodded and said, "Yes!" A cultivation system called the Yuan Wheel! ”

Chen Zong pondered for a while when he heard this, and couldn't help but say to Gu Shuang: "Do you want to promote?" ”

"Yes!"

Chen Zong was slightly moved when he heard this, and asked Gu Shuang, "Aren't you afraid that someone will surpass you?" You know, strength is such a thing, but Pandora's box... Once there are people with ill intentions and strong strength, they will no longer respect you as much as they do now..."

Gu Shuang shook his head when he heard this, and smiled freely: "Afraid? Now there are a lot of monsters out there that surpass me, and I'm not afraid..."

When Chen Zong heard this, he groaned: "Sometimes, the monsters in people's hearts are more terrible than monsters!" ”

When Gu Shuang heard this, he glanced at Chen Zong and said with a smile: "Maybe so, but I am also a human ......"

Hearing Gu Shuang's words, Chen Zong was slightly stunned, and then looked up at Gu Shuang, at this moment, Gu Shuang was smiling and looking into the distance, but Chen Zong always felt furious and shuddered when he saw Gu Shuang's smile.

Seeing this, Gu Shuang patted his forehead with some amusement, opened the topic and said with a smile: "Okay, let's not talk about this, Yuanlun cultivation system, I have only summarized a little bit at the moment, and there are still two problems that have not been solved!" ”

Seeing this, Chen Zong breathed a sigh of relief slightly, I don't know why, when he saw Gu Shuang just now, he seemed to see the gloomy malice like an abyss, exuding a terrifying aura, making him feel stunned in his heart, and he was about to lose his breath.

"Can you talk about your Yuanlun cultivation system?"

After settling down, Chen Zong asked.

Hearing this, Gu Shuang said: "This set of Yuan Wheel system is built on an internal circulation system, when the cultivator goes through the energy baptism, an energy circulation system will appear in the body, through this system, the cultivator can absorb the external cosmic energy to strengthen his body cells, making himself extremely strong, at present, there are two problems I need to solve, one, what kind of energy baptism can stimulate the Yuan Wheel, two, is what I just said, I have encountered a bottleneck, This bottleneck hindered my deduction......."

In fact, Gu Shuang encountered not only these two problems, but many, but Gu Shuang did not say them explicitly for the sake of secrecy.

An obvious problem is that human beings and mutants are not the same, if human beings want to cultivate, Gu Shuang must prevent someone from stepping on the warning line in the process of cultivation, in order to obtain stronger strength, he should not be a human being, and become a mutant, this point needs to be covered up by Gu Shuang through various ways, so that those cultivators will not dare to touch this warning line in the future.

For this point, Gu Shuang decided to distinguish between 'demons', and dared to cross this line, so he beat them into 'demons'.

Secondly, the treatment of harmful energy and harmless energy.

According to Gu Shuang's speculation, when the cells are strengthened to a certain extent, they will absorb harmful energy and may not mutate again.

Then before that, Gu Shuang needed to find a kind of energy that was absolutely harmless and endless for cultivators to cultivate, and it was best for those cultivators in the future to only absorb this kind of energy, so as to completely eliminate the possibility of becoming a mutant species.

Secondly, there are a lot of small details, and there are too many to count.

When Chen Zong listened to Gu Shuang's description, he fell into deep thought, and after a while, Chen Zong raised his head and said: "The bottleneck problem you mentioned, I have encountered it before, when I practiced martial arts in the past, once, I always felt that the speed of my sword technique had reached the limit, as if there was a layer of shackles, trapping myself..."

Gu Shuang's eyes were happy when he heard this, and he asked, "How did the senior brother solve it later?" “

Hearing this, Chen Zong stood up, looked at the sky and pondered: "At that time, our master had not yet gone to the immortal, so I went to ask the master, and the master said that this is a natural thing, and he provided me with three ways to break the shackles, the first is to take my time, this is called water to come naturally, the second is to continue to practice, this is called the retreat, and the third way..."

Hearing this, Gu Shuang nodded thoughtfully, and then asked, "What is the third type?" ”

Chen Zong pondered for a while and said, "Master said that there is a great terror between life and death, as long as you surrender this great terror, the shackles will be automatically broken!" ”

"There is a great terror between life and death?"

Gu Shuang frowned slightly when he heard this, he had been in danger several times, and he was already not afraid of life and death.

This method seems to be of no use to him anymore...

After chatting with Chen Zong for a while, Gu Shuang returned to the Eastern Federation Energy Control Room, at this moment, he was sitting in the forty-sixth level area of the Energy Transportation Room, the energy here was very violent, but Gu Shuang was not afraid, he was pondering, thinking about the way to break the shackles.

"There is a great horror between life and death....."

Gu Shuang frowned slightly, he had tried this kind of horror once, that is, when he activated the mass core, at that time, the mass core was not activated, the oxygen in the mecha was starved, and his life fell into a countdown, he clearly experienced this great horror.

Another time, when Gu Shuang confronted Lu Yiluo, Lu Yiluo's subordinates wanted to kill him, and the tip of the sword was only a few tenths of a millimeter from his neck, but he still did not waver.
