At the end of the fourth day of cultivation, Gu Lei felt that his spiritual power was as strong as a burning flame, and his ears and eyes were clear, and his body was as light as a swallow.

He jumped to the roof, and with a punch, there was a strong wind that blew the teacups on the table.

Then he contemplated, took a deep breath, and his spiritual power "stained" the air, and there was immediately a sense of warmth in his lungs, flowing into his limbs and hundreds of bones with the respiratory and blood circulation system.

Then, under his deliberate guidance, all the heat was concentrated on the right palm, and after the right palm changed from hot air to faint redness, he slapped it out, and a faint red handprint flew out of his hand, overturning the teacup at once, rolling to the ground, and shattering into pieces with a "pop".

"Is this the power of the first order of the entry realm? If I had cultivated dragon qi earlier, I wouldn't have been bullied so often. ”

Gu Lei was immersed in the sudden increase in strength, and he was a little difficult to extricate himself.

"It's thanks to the cultivation of the Dog Dragon Breathing Method."

If the "dyed" dragon qi wants to act on foreign objects, it must also pass through the breathing channel. But among all the breathing channels, the mouth and nose are the most important, and it is because of this that the mouth and spit dragon qi bullets have become a common attack method for low-level cultivators. This is also the reason why criminals in the Blue Sun System are often forced to put a mouth plug ball.

Undeveloped, the amount of air breathed by the skin is generally less than 1% of the total breath. Even after development, the general dragon-level breathing method can only gradually develop the skin breathing to about 10%. However, the Dog Dragon Breathing Method can develop skin breathing to a maximum of 20%, and Gu Lei's skin breathing can be developed to nearly 5% in three days.

Otherwise, Gu Lei could only blow the teacup down with his mouth.

Its practical mouth is nothing, but once the dragon qi is separated from the body, it will soon become an ordinary gas, and its usefulness will be limited a lot. The high degree of skin respiration development still has many advantages at present.

Gu Lei compared the application methods of various dragon qi in his mind.

Anyway, as soon as the blessing was over, his cultivation speed was like a turtle crawling, and he couldn't bear it at all.

So, he actively thought about how to defeat the demons in exchange for more blessings from the little white fairy.

Said Cao Cao, Cao Cao arrived, a fragrant wind came to his face, and the little white fairy moved the lotus step lightly, and the money came.

At present, Gu Lei, whose confidence has skyrocketed, said awe-inspiringly:

"Where's the Demon King?"

Xiaobai covered his face with his sleeves and let out a fox laugh that succeeded in his treacherous scheme:

"Oh hehehehe......"

……

The demon cloud has been spreading from the sky to the ground, and with the flash of thunder, Gu Lei can barely get a glimpse of the demon mountain from the tumbling demonic qi. Irregularity was the first impression that the Heart Demon Mountain Range gave him.

Can that be called a mountain range?

Gu Lei clenched his fists, so nervous that he forgot to worry about whether the cracked city wall under his feet would collapse.

In his impression, the mountains should naturally be sharp at the top and wide at the bottom, but most of the peaks in the Heart Demon Mountain Range exposed from the demonic qi were not like this, and there were many strange shapes abound.

And if he saw more of their shapes, the strange outline would turn into some kind of unknown rune in his eyes, revealing a power that made him tremble instinctively. That feeling is the one who has to describe it in four words - the enemy of life.

The wind was blowing with a foul smell, and the wind was faintly accompanied by a strange whistling sound.

Gu Lei listened carefully, and then looked carefully, and then his pupils shrank, and his legs and feet became weak uncontrollably.

In fact, there was a demon thunder that had turned into a dragon form, and was churning and soaring in the demon cloud, emitting bursts of tyrannical roars.

Could it be that the Demon King? How can I get through this?

He turned his head to look at the smiling Xiaobai and asked in shock:

"Do you think that with me, a little salted fish of the first order of the entry realm, I can beat that demon king?"

"Oh, hehe."

The little white monster laughed, feeling that it was out of place, and turned to comfort him softly:

"Don't worry, that's not the Demon King, the real Demon King, when you raise your strength to the seventh or eighth order, you will definitely be able to defeat him."

"Oh, really? So, haha, hehe. ”

Feeling a beam of disdain from behind Xiao Bai, Gu Lei smiled dryly to hide his embarrassment.

The young man's name is Gu Yong, not only has the same surname and age as him, but even his appearance is like an eight-point like him. When they met for the first time, Gu Lei almost regarded him as a triplet brother who had been separated in another world.

Yes, triplets. On Xiaobai's other side, there is also an identical young man named Gu Xin, who is Gu Yong's real brother.

Gu Xin smiled bitterly and cast an apologetic look at him. Compared with Gu Yong, who is a little reckless, he is much gentler and steady.

Gu Lei shook his head, not surprised, after all, his performance was indeed much worse than him.

The mutilated bodies of the two brothers Gu Yong and Gu Xin witnessed their bravery, Gu Xin wore an eyepatch on his left eye, Gu Yong was even more miserable, not to mention the loss of his left arm, and his right calf was also a prosthetic.

Are they the brave ones who have been summoned from other universes before?

The more Gu Lei thought about it, the more he felt that it was possible.

I don't know if it's because the local people in the heart realm are too simple, and talking to the local people will always give Gu Lei a feeling of talking to a simple intelligent robot. In comparison, the language expressions of the Gu Yong and Gu Xin brothers are much richer.

No wonder it's called Honest Village! However, the mental realm is too dangerous! Am I just an ordinary junior high school student? On the tinkling Timeson 3, I've never even seen an interstellar pirate!

Regardless of the little entanglement in Gu Lei's heart, Xiao Bai continued to take care of himself:

"As long as you work hard to slay the demons in your heart and obtain a large amount of Chaos Crystals, your cultivation will soon reach the seventh or eighth order. My blessing to you is actually to crystallize the remaining chaos in the warehouse into spiritual energy for you to absorb. ”

"Chaos Crystal?"

"Yes, do you know what chaos is?"

"I don't know."

"Chaos is the crystallization of negative energy."

"Negative energy?"

"Have you ever heard of Duke Albert's intelligent transformation theorem?"

"Well, Albert, the 'God of War'."

Gu Lei's tone was full of mixed emotions, representing the attitude of all the people of Camilla towards Duke Albert.

On the one hand, Duke Albert is the chief scientist of the Atomic Energy Research Institute of the Later West Sea Empire, and his mass-energy conversion theorem indirectly spawns the theory of public ownership of property rights, which is the foundation of the proud founding of the Republic of Camilla.

On the other hand, he was also the commander-in-chief of the Imperial Expeditionary Force in the First Galactic War, and even if he strictly adhered to the ethics of a warrior and had a noble character that even many soldiers and civilians of the Republic admired, he had brought extremely serious disasters to the Republic after all.

"Mass is energy, according to the mass-energy conversion theorem, you think that matter and even life are essentially composed of energy under the action of the four forces, right?"

"Isn't it?"

"It's not just that."

“……”

"To be precise, all material life is formed in the confrontation between energy and negative energy."

“……”

"All material life is composed of atoms on a microscopic level, imagine that the atoms that are moving in disorder want to coalesce into an orderly whole, isn't this a process in which two forces play against each other?"

“……”

"One is the force that drives all the atoms apart, and the other is the force that pulls all the atoms together, which are energy and negative energy."

“……”

"If energy is the power of gathering, then negative energy is the force of separation. If the energy overpowers the negative energy, the atoms and molecules gather, the material life is born, and the universe prospers. Once the negative energy overwhelms the energy, the particles will be chaotic and disorderly, the matter will be weathered, life will decay, and the universe will expand and go to destruction. ”

"To be honest, I still don't understand."

Gu Lei scratched his head embarrassedly.

"It doesn't matter, you just need to know that negative energy is as ubiquitous as energy, and it is also the basic force engraved in the depths of matter and even the soul of life."

Xiao Bai deliberately accentuated the pronunciation here in the depths of his soul, which made Gu Lei's heart move.

Soul? Two powers?

Without waiting for him to think deeply, Xiaobai pointed behind him and said:

"Attention, the demon is coming."
