Turning over and getting out of bed, I moved my body, without the slightest discomfort, but felt that the true qi was full, and the real qi in my body was extremely comfortable. "Ah!, what's going on", the thunderstorm on his head was stunned.

"Little stone, what's wrong with my sea of knowledge, why is it empty?"

As a machine spirit, the little stone is connected with the master's consciousness, and as soon as he listens to him, he immediately senses the change of the thunderstorm's sea of knowledge, "Wow, that's great!, master, your sea of knowledge has expanded so much, it's a full ten meters square", the little stone cheered in surprise.

"Is there something wrong?"

"No, that's a great thing. I'll just say, the cultivation technique of this demon path will be of great benefit to you, master, now you know", Xiao Shi said with a proud look and raised his head.

"The strength of the divine consciousness is first reflected in the size of the sea space. The sea is made up of neurons. The larger the sea of consciousness, the thicker and stronger the neurons, and of course, the stronger the consciousness will be," Xiao Shi explained.

"With such a large space, how can my head fit in?", Lei Yu touched his normal-sized head, and used his divine sense to explore the space within a radius of ten meters, and the goose egg-sized fog left by the master floated above the sea of knowledge, not as full of brains as before. The space was surrounded by dense mesh pipes, and he asked the small stone in puzzlement.

"The hosts were really, so hilarious. Zhihai is the center of neurons, and it is the mustard seed space opened up by neurons, and the space of those powerful people can accommodate hundreds of rivers and seas, whose head will be so big, haha", Xiaoshi saw the thunderstorm and touched his head, and explained with a smile.

"Oh?".

"Master, let's go and feel it in the sea."

"How to get there?", Lei Yu was a little confused, can the brain enter, it's too mysterious.

"Try it with your mind".

As soon as Lei Yu thought about going in, he felt a "whoosh", and he appeared in the sea space, and the small stone was also there. It feels weird, like a goose feather, floating in the sea of knowledge, exactly the same as the feeling when Yujian Xiaoshi was the first time, and it is wonderful.

"Master, now you are the primordial spirit transfiguration form, not the body is really in it, so you will have such a feeling, and you will get used to it after a few more times."

"Oh, that's how it is", Lei Yu suddenly realized, this feeling is really weird.

"What's the use of this space?".

"In the future, you can put the instrument in it for practice, as long as the master wants, you can put anything, or you can practice in it."

"Oh, got it".

Consciousness returned to reality from the sea of knowledge, and Lei Yu was excited at this time, and the impact of his own moment would actually expand the sea of knowledge to so much, and the risk was really worth taking.

Thinking of this, he cautiously tried to get up, controlled the reverse true qi into a thread, and tried to run from the Jade Pillow Acupoint to the Baihui Acupoint, preparing in his heart, once he felt uncomfortable, he would stop immediately.

Carefully drove this trace of true qi to run, and the result was that it passed without hindrance, and with joy in his heart, he thickened his true qi a little more, and still passed smoothly.

Lei Yu was overjoyed in his heart, and then tried it with a normal size of True Qi, and there was no problem at all.

In turn, driving the true qi from the Baihui acupoint to the jade pillow acupoint is also unimpeded.

"Little stone, get through, no problem", Lei Yu said excitedly, the bottleneck is solved, and you can use any kind of exercise method in the future.

In the excitement, Lei Yu stretched out his arm casually, and a true qi surged to his fingers. Suddenly, a black flame the size of a soybean appeared on the tip of Thunderstorm's fingers, and although the flame was small, it was extremely hot.

"It's finally successful", Thunderstorm was excited again, and finally sacrificed the flame for the first time and mastered the first spell.

"Great, master, the flame you sacrificed is black, its grade can be high, the people who can sacrifice the black flame are also only a handful in the cultivation realm, and if you refine the pill and qi in the future, this high-grade flame will be very useful", Xiao Shi said excitedly.

"Yes, when I have time in the future, I really want to learn alchemy."

In the cultivation room, Lei Yu repeatedly practiced sacrificing flames, and after dozens of days of cultivation, the control and application ability of true qi has been greatly improved, and the flames emitted have increased a lot, almost the size of a pigeon's egg.

"Master, you can bless the lightning sand in the flames, that way, it will be more powerful when you encounter the enemy," Xiao Shi suggested.

"Thunderbolt sand?, where to find thunderbolt sand?".

"Hehe, in that fireball in the Blood Thunder Bead, there is thunder and lightning sand, which is inexhaustible, you see", Xiao Shi said as he handed a black grain of sand to Thunderstorm.

"Just this grain of sand?, how to bless it?", Lei Yu said incomprehensibly.

"Put it in the sea of knowledge, and when you sacrifice the flame, try to sacrifice it together, and I will collect some for you," said Xiaoshi, handing a small bag of these sand grains to Thunderstorm.

As soon as the divine consciousness moved, the pouch entered the sea of consciousness of the thunderstorm. Then, Lei Yu stretched out his hand and offered a black flame, feeling a small stone say that the thunder and lightning beads were inside, shooting towards a big tree ten meters away.

The sound of "boom!" was accompanied by a strong flash of lightning, and the big tree was blasted out of a large hole, and the area around the hole was scorched black.

"This thunder and lightning sand is too powerful!", Lei Yu looked at the big tree that was blown up, stunned for a moment, and then said excitedly, if it is the enemy, it is strange not to blow the enemy into meat sauce.

"Well, it's not bad, when you increase your cultivation and successfully refine the fire essence in the fireball, the scorching fireball that emits a blessing of thunder and lightning sand will be called powerful," Xiao Shi said.

"That fireball still contains fire essence?", "Appreciation of Treasures in the Xiuzhen Realm" mentioned fire essence when talking about fire, can be called "fire essence", the grade of the fire must be at least above level six, the higher the grade, the higher the temperature contained in the fire, and of course, the more difficult it is to find.

"Of course, you can come and see, master," said Xiao Shi proudly.

There was still some distance to get close to the power source of the Blood Thunder Bead, and the thunderstorm felt the scorching temperature from the fireball rushing towards his face, and the real air turned, and the pressing flame made him feel a lot better.

A fireball composed of molten liquid, molten and tumbling, surrounded by lightning and thunder, a powerful magnetic explosion is generated from the fireball from time to time, the molten liquid erupts like a volcano, and then is pulled back into the fireball by an invisible force field, the scene is extremely terrifying.

"Look at the little white fire in the molten Lang, that's the fire spirit," the little stone said eagerly.

At this time, although the person stood with the small stone, his consciousness was constantly pulled back to the past, and there was always a voice calling him in the depths of his heart, which was so familiar but ignorant.

Hearing the call of the little stone pulled his consciousness back to reality.

"Oh, see, come back later," Thunderstorm replied wistfully and absent-mindedly.

......

In the cultivation room, after successfully practicing and mastering the Thunderbolt Technique (Xiao Shi insisted on taking this name), Lei Yu quickly mastered the "Wind Resisting Technique" in the elementary chapter.

As the name suggests, "resisting the wind" is to harness the wind and use the ubiquitous wind liliang to complete actions that cannot be done normally.

When Thunderstorm has cultivated the Wind Resisting Spell and has the initial ability to communicate with the wind, the two hearts of the Demon Dao are cultivated as one**, and the Wind Resisting Spell is completely reflected.

In principle, the true path cultivator resists the wind, which is to absorb the wind energy by consuming the true qi and causing negative pressure to be generated around the body, especially the limbs, so as to achieve the wind, and the consumption of the true qi is quite large. The amount of true qi stored in the body is linked to the level of cultivation, no matter how high the cultivation is, the stored true qi will always be exhausted, so it is impossible to resist the wind for a long time, and consume all the true qi on it.

And the Demon Dao cultivation method is achieved through the integration of two hearts, and the matter of resisting the wind can be easily realized, think about it, it is already relying on the limbs and the body to absorb the aura of heaven and earth, when resisting the wind, you only need to consciously control the acupuncture points, the parts that need the blessing of the wind, the acupuncture points are opened, and the parts that are not needed are closed on the acupuncture points, and there is no need to consume the true qi at all.

To put it more bluntly, while resisting the wind, he is absorbing the aura of heaven and earth, so how can he use it and consume it.

Comparing the two methods, Lei Yu was really overjoyed: "I never thought that after cultivating that demon Dao**, it would bring so many benefits to myself", in the open space outside the mountain hut, Lei Yu's consciousness moved, and the acupuncture points on his legs were automatically absorbed, without shadow and color, The gentle breath wrapped around the legs, stride, never expected that this step would be a few feet away, the center of gravity was unstable, immediately poured forward, the other acupuncture points automatically opened, a lifting force was born, easily a donkey rolled, stood up, stared straight at this stride, actually crossed such a long distance, and the balance of the body, is so incredible, I can't believe it.

In the following days, Lei Yu was completely immersed in the shijie of the wind, constantly practicing, constantly working on precision, repeatedly shiyan, and gradually became familiar with the precise control of the opening and closing of the body's acupuncture points, making it gradually become a conditioned reflex, so as to achieve the ability to accurately resist the wind, and became the driver of this wind power.

When resisting the wind, let the acupuncture points of the whole body gradually form a conditioned reflex, and the running speed of the thunderstorm is not an exaggeration to describe it as an afterimage. Punch out, wait to hit the target, only to hear the fist and air friction produced by the sharp sound of breaking the air, use the opening and closing of acupuncture points, control the resistance of the wind, after the thunderstorm rises, in the air can make the descent speed slower, stay a little longer. Make all kinds of extremely difficult and incredible movements, postures, and pauses at will, and use the thrust, drag, bearing capacity, and acceleration of the wind to the extreme.

In the process of resisting the wind, Lei Yu also knew his shortcomings: "The cultivation time of the magic skill is too short, the strength to absorb gas is not enough, and the action I want to do cannot be fully realized or delayed due to insufficient suction power."

It's just that he knows in his heart: "As the cultivation time increases, after his cultivation level rises, these are not problems."
