Gu Shuang really doesn't know how to cultivate, his strength depends on the quality core, there is energy in the quality core, he has S-level strength when he is wrapped in black matter, and if he doesn't have energy, he will be beaten back to his original form.

And Gu Shuang's sword technique, the Thirteen Swords of Jinghong came from his senior brother, Chen Zong, who had just practiced to the point of 'tangible', because of his own strength, so the power of the sword technique was multiplied in his hands.

As for cultivation, Chen Zong doesn't know how to cultivate, for the use of strength and strength, Chen Zong can play tricks, but when it comes to how to cultivate, what kind of thing cultivation is, Chen Zong is a Muggle, worse than Gu Shuang.

Because of the appearance of the internal circulation system in his body, Gu Shuang has a certain understanding of how to cultivate and become stronger, but he only crosses the river by feeling the stones, and he doesn't know anything about it, because there is no master to teach him! He's not a genius, he knows so much.

At this moment, Gu Shuang looked at the twelve little guys who were sitting on the ground in front of him, meditating, absorbing the cosmic energy in the air, and it seemed that they were cultivating, and a terrifying light appeared in his eyes!

I saw Gu Shuang take an unfathomable glance at Cao Shuang, and said lightly: "Cultivation? Of course I do! Your eldest brother Gu has S-level strength, and you still need to teach this? ”

After speaking, Gu Shuang turned his head, and seeing this, Cao Shuang let out an 'oh', then lowered his head, closed his eyes, and continued to absorb the energy in the universe and cultivate.

Seeing this, Gu Shuang waited for a while, turned his back to Cao Shuang, and said mysteriously: "Cao Shuang, you are very talented in cultivation..."

"Huh?" Cao Shuang was a little confused, his face turned red, so he had to nod and reply: "Thank you Brother Gu for your compliment!" ”

Before his words landed, he heard Gu Shuang turn his back to him and say calmly: "But talent alone is not enough!" Work is still needed! So be it! I'm going to test you and see if your foundation is solid! ”

"Well, you want to test me?"

Cao Shuang didn't think much about it, and after bowing to Gu Shuang seriously, he said respectfully: "Brother Gu, please ask for the question!" ”

Hearing this, Gu Shuang smiled mysteriously and said, "Yo! I'm so confident! So be it! First tell me who your master is, and let me see which faction you are."

"Factions? Are there still factions? ”

Cao Shuang asked suspiciously, and Gu Shuang blurted out: "Aren't all novels... Ahem! If you say it, you can say it! Brother Gu, this is reminding you to remember your master all the time! Remember the master's goodness, understand? Gu Shuang turned his back to Cao Shuang and said with majesty.

Cao Shuang was a little confused when he heard the first half of Gu Shuang's sentence, and when he heard the second half of the sentence, he felt that what Gu Shuang said was quite reasonable, and he didn't think much about it, and after bowing respectfully to Gu Shuang, he said, "Yes!" Xiao Shuang knows! The way of cultivation is taught by the leader, the leader is as wise as the sea, and it took several years to find a set of cultivation methods and pass them on to the clansmen, I will always remember that the leader is great! ”

It turned out to be taught by Lu Yiluo, Gu Shuang's eyes flashed, and he felt a little regretful, he knew that he should have asked Lu Yiluo more, after thinking about it, Gu Shuang said calmly: "Well! Not bad! The children can be taught! So now, let's tell Brother Gu what the first lesson of the leader taught you! You have to pay attention! I'm pretty familiar with the leader of your family! If you're wrong, you're going to have to eat the board! ”

"Xiao Shuang has a good memory, and he will never go wrong!" Cao Shuang replied with some confidence, his expression a little smug.

"Say it!"

"Yes! The first class of the leader taught Xiao Shuang to know the Yuan Wheel and the energy in the universe, and Brother Gu wants to test Xiao Shuang? ”

Yuan Wheel? This is probably a name given to the internal circulation system by Lu Yiluo, right? It's quite vivid. Gu Shuang chewed for a while, he knew what the Yuan Wheel was, thought about it and said, "Let's test the energy in the universe first!" ”

"Yes! The leader said that the energy in the universe is divided into two forms, visible and invisible, and harmful and harmless, and the reason why we have mutation is because we absorb harmless energy at the same time, we also absorb harmful energy, harmful energy can make people mutate, and harmless energy can make people strong, and the leader said that because we have mutated, we can absorb both harmful energy and harmless energy. ”

Harmful? Gu Shuang nodded thoughtfully, knowing why he felt that his cells were going to mutate when he absorbed the cosmic energy.

"It seems that if humans want to cultivate, they must absorb harmless energy..."

After thinking about it, Gu Shuang pretended to be an examiner and asked, "Yes, let me ask you again, how to distinguish between harmful energy and harmless energy?" ”

Cao Shuang replied: "Lord Leader said that harmful energy is unstable, while harmless energy is stable and can be distinguished by perception. The leader also compares that if the harmful energy is a hedgehog ball, then the harmless energy is a smooth seed, because we have mutated, we can peel off the thorns of the hedgehog ball to obtain the inner energy, if there is no mutation, we will be harmed, and the harmless energy when we absorb it, because its shell is smooth, all that will not bring us harm, can easily peel off its shell and obtain the inner energy. ”

Inner energy? Gu Shuang's eyes narrowed, and he found a commonality from Cao Shuang's parable of Lu Yiluo, that is, whether it is absorbing harmful energy or harmless energy, it is necessary to peel off its shell and absorb its inner energy.

"I don't have mutations, so unlike plant species, the heart and skin can't completely peel off the 'hedgehog shell' of harmful energy, so when absorbing the energy of the universe, there will be a feeling of cell mutation, once there is too much, it will really mutate, and the plant species their cells have mutated, and the skin can not only peel off the shell of harmless energy, but also easily peel off the 'hedgehog shell' of harmful energy!"

Gu Shuang thought for a while, and then asked Cao Shuang in general: "Lord Leader taught you that energy has two forms, visible and invisible, so I will ask now, among the cosmic energy, which ones are visible and which are invisible?" ”

Cao Shuang replied: "The leader said that there are diversity in the existence of energy, sunshine, rain and dew, oxygen and so on in the pre-earth era are all energy, but the content is very low, so it can't make people stronger, can't make people mutate, but after the membrane that protects the earth is broken, in the universe, the energy emitted by those stars, the energy contained in the universe itself, is all transmitted to the earth, and the energy content of these energies is very high, so it can make people stronger and mutate." And among these energies, some are in the form of rays, which can be seen, some are not in the form of rays, and are outside the spectrum, so they are invisible to the naked eye, but can be perceived with the frequency of thought waves, and some are completely deviated from the spectrum, completely invisible, and perceptible. Therefore, as long as the cosmic energy is perceptible, it is visible, and as long as it is imperceptible, it is invisible. Therefore, visible energy is also called light energy, and invisible energy is also called dark energy. “

Gu Shuang was stunned when he heard this, and couldn't help but sigh, Lu Yiluo is really a genius! It took thousands of years for humans to discover dark energy, and it only took her a few years to discover it!

Gu Shuang chewed for a while, and found that Lu Yiluo not only discovered dark energy, but also explained it very reasonably, this is really... Gu Shuang suddenly felt a little inferior, thinking that before, when he first knew about dark energy, he thought that dark energy was just black energy...

Gu Shuang secretly glanced back at Cao Shuang, who was lying on the ground respectfully, waiting for his own examination.

Thinking about it, Gu Shuang felt a little embarrassed, and his old face blushed a little, but in an instant, he returned to normal.

"Ahem! Very good! Xiao Shuang! You really didn't disappoint me, it seems that you really wrote down everything that the Lord Leader taught you, not bad! The children can be taught! ”

Hearing this, Cao Shuang was overjoyed, probably the first time he was praised, and he blushed a little embarrassed, and then said confidently: "Brother Gu!" What's the problem, just let the horses come! ”

That's great! Gu's eyes narrowed, and he was overjoyed in his heart.
