A separate building in Sichuan, China, ten kilometers away from a military base.

Since the development of the brain domain, Long Xingyu has not even been to the base in the past few days, just like a child who has gotten a beloved toy, he has been practicing mental power control every day for the past few days. At this time, he was sitting at the table, controlling the pen and doing the work of writing, although the writing was still relatively crooked, but it was much better than at the beginning.

A figure suddenly appeared in front of Long Xingyu, distracting his thoughts, and the pen immediately fell, splashing ink all over the paper.

"Big brother, why are you here?" raised his head, looking at the big brother who appeared in front of him in some surprise.

A silver ring crossed an arc and landed on the table, "You take this True Dragon Holy Ring, cut your finger and drop a drop of blood, and then refine it." ”

"Eh, is it a drop of blood to recognize the Lord?" Long Xingyu said with some doubts. Although he was puzzled, he still did as his eldest brother said. When he refined the ring, a strange look appeared on his face. "It's ...... How could there be such a large space, it's incredible. ”

"Isn't it strange, this is not an ordinary space ring, its effect, you can slowly explore it yourself. "Sitting in an old chair, with a bottle of wine in his hand, he poured it in one gulp. "Let me remind you, there are five layers of space in the True Dragon Holy Ring, and with your current strength, you can barely enter the first layer, and as for the later layers, they are not what you can explore now. ”

"Could it be that I am now 92% of my brain domain development degree, and my spiritual energy has reached the innate sixfold level?" Long Xingyu looked at his eldest brother with some surprise.

"Why, do you think that 92% of the brain domain development degree is very strong! You must know that the innate realm is nothing, if it comes to cultivation, innate is just the lowest threshold. Reaching the peak, it is only at the level of the illusory period, although it can prolong its life by four hundred, but it will eventually turn to dust. Only by pursuing the Heavenly Dao can we truly cultivate the way. Long Aotian sighed softly.

"Could it be that you have already broken through the innate peak, big brother?" Long Xingyu said a little excitedly, "What is above the innate peak?"

"Hehe, if you are only in the space of the earth, lack of aura, and want to break through the innate and go further, it is almost impossible, if there is no great opportunity, then it can only be the old loess and fall into reincarnation. Long Aotian said lightly.

"You remember, in the path of cultivation, you must not be too ambitious, only by laying a solid foundation will you have a chance to go further. After a pause, he said: "There are still many good things in the True Dragon Ring, you can slowly explore and discover them yourself." Then he got up and left.

The spiritual power probed into the True Dragon Ring, and immediately, Long Xingyu felt that his whole person seemed to be sucked into an infinite space, and the surrounding area was gray and chaotic.

A thunderbolt flashed, and the whole heaven and earth were divided, the clear ones floated up into the sky, and the turbid ones sank into the earth. Yin and Yang are separated. Metal, wood, water, fire, earth, the five elements are born suddenly, and they turn into mountains, rivers, lava, lakes, wind and clouds, thunder and lightning, and become gossip when they merge with heaven and earth. Immediately, flowers and trees, insects and fish, birds and beasts, spirits, and all things are derived. Suddenly, a giant sword flew from the sky and plunged straight into the top of the mountain, but strangely, everything around it seemed to be unaffected.

The spiritual power of the giant sword thousands of miles away, Long Xingyu felt a sword intent from the giant sword that defied all things and was proud of heaven and earth, and there were two big characters engraved on the sword "Aotian".

With this huge long sword, feeling the pride of the sky, Long Xingyu only wanted to incarnate himself into the giant sword, standing proudly in the world like it, looking down on the common people.

Huo Ran woke up in shock, and the giant sword was shocked. This sword can capture people's hearts and souls and influence people's minds to such an extent. If it weren't for the pendant on his neck that released a clear stream at the critical moment, he couldn't have said that he had been sucked out of his soul by the giant sword, and he couldn't have said that he would have turned into a vegetative state.

"I didn't expect this pendant to have the effect of stabilizing the mind, it's really a good thing. Long Aotian held the pendant in his hand and bowed his head. "However, why did the ring given by the eldest brother have such a change? ”

Shaking his head, he put his thoughts aside. Carefully looked at the entire ring space, only to see the mountains in the distance, a large river, winding away, the sky was chaotic, but on the ground did not feel the slightest dimness. The giant sword stood on the top of the peak, connecting the heavens and the earth, and the chaotic qi in the sky formed a huge whirlpool, gathering on the giant sword. Above the sky, there was a gray chaos, no sun rising, no moon falling, only smoke and clouds covering the sky, covering the entire sky. A vast wilderness stretched out to the mountains in the distance. Moreover, Long Xingyu also found that in this space, there was a lot of heaven and earth aura, at least more than a thousand times the current space of the earth, which made him feel a lot of emotion.

In the mountains, there were torrential rains, clouds and mist, winds, lightning and thunder.

Long Xingyu walked forward slowly, feeling this space carefully along the way, the spiritual power spread, and in an instant, it enveloped a radius of tens of thousands of meters, but he found that this range was undoubtedly pitiful compared to the ring space.

"Hasn't the ring been refined by me, why do I feel like I can't fully grasp it?" Long Xingyu frowned, "Big brother said that there are five layers of space within the ring, and this should only be the first layer of space." But even so, with my mental power, I can't even cover one ten-thousandth of this space, which is too ridiculous. Forget it, just walk slowly. Thinking about it, Long Xingyu sped up and walked forward.

Huo Ran seemed to think of something, Long Xingyu stopped and withdrew the spiritual power that spread out. Wrapped his spiritual power in himself, he immediately found that he could fly, and excitedly raised his head to the sky and roared, flying towards the mountains in the distance. On the first flight, Long Xingyu didn't dare to be too fast, and in order to be safe, his spiritual power always completely wrapped himself.

After flying for a while, Long Xingyu carefully released his spiritual power, for fear that one would accidentally fall. As the flight time grew, Long Xingyu became more proficient in his flight control, and the range of spiritual power release expanded to a radius of kilometers.

When Long Xingyu flew to the top of the river, he saw the vast river passing away in the distance, but a tributary flowed into the mountains. Looking at the reckless mountains, Long Xingyu released his thoughts to the maximum, the birds and beasts in the mountains, and the swimming fish in the water, all have their own lives, and they are not affected by other things.

In the middle of the mountains, there is a huge valley surrounded by trees and cliffs, into which the water of the tributaries flows. The vicinity of the valley was filled with a purple aura, and this unknown purple qi could block people's spiritual exploration.

Curious, Long Xingyu flew in the direction of the valley. When he arrived at the mouth of the valley, he landed on the ground, carefully sensed the surroundings, and there was no dangerous aura, so Long Xingyu raised his feet and walked into this unknown purple qi, and suddenly felt the purple qi pouring in from the pores of his whole body, and his whole body was extremely comfortable. The spiritual power relaxed, and one after another purple qi entered Long Xingyu's body, but then it flowed out from his body surface, and in the process, Long Xingyu only felt lazy all over his body, making him not want to wake up from it.

But at this moment, in the pendant on his chest, there was another cool feeling, which woke up the inextricable Long Xingyu.

Some frightened around, "There seems to be no danger here, but in fact, there are dangers." The more you feel that it is not dangerous, the more dangerous it is. Thinking in his heart, he didn't dare to slack off at the moment, cheered up, gathered all his spiritual power, and carefully spread all over his body, not letting the purple qi enter his body. hesitated slightly, but then Long Xingyu resolutely took a step and walked towards the valley.

A burst of purple qi surged, and a figure walked out of it. Looking at the valley in front of him that seemed to have not been invaded for thousands of years, Long Xingyu felt a little surprised. In the distance, there is a lake with a radius of tens of thousands of miles, where the tributaries converge. The nearby lake water is green, there are strange fish swimming and playing, and there are countless stones at the bottom of the lake, all of which are smooth and blue.

As soon as his mind moved, his spiritual power penetrated into the bottom of the lake, and when his spiritual power spread thousands of feet away, he suddenly felt a cold air invade his spirit. After thinking about it, he continued to probe his spiritual power, only to feel that the water was getting colder and colder, and it seemed to have dropped to freezing, but the lake water was not frozen, and he felt strange in his heart, so Long Xingyu continued to extend his spiritual power.

The further down the lake went, the colder it became, until it reached a depth of nearly a kilometer, and the temperature of the lake was approaching minus 60 degrees. Although some exceeded his limit, Long Xingyu was unwilling to give up, "I must know what is going on, what makes the lake water drop to such a low temperature, and how does it keep the lake from freezing into ice." ”

Finally, when he was about to take it anymore, he suddenly found that the temperature under the water no longer changed, and seemed to be frozen at minus 80 degrees. So he gathered his confidence, "It should be almost fruitful." Thinking about it, Long Xingyu's spiritual power quickly went underwater.

A white light pierced the bleak underwater world, and a huge crystal-like majestic palace appeared in front of Long Xingyu's eyes, "This is ......" A little unable to believe his spiritual power, Long Xingyu on the shore opened his mouth wide.

After a few breaths, he finally made up his mind. Seeing the figure flash, he had already entered the lake and swam quickly in the direction sensed by his spiritual power. During this period, a strange fish with a body length of one meter suddenly appeared around Long Xingyu. In his heart, he was shocked that his spiritual power had not found these big fish, which really surprised him. Fortunately, these strange fish don't seem to have any ill will towards themselves, just cruising around them. Shaking his head, he continued to swim towards the Crystal Palace.

When he arrived at this crystal palace in the distance, Long Xingyu found that this palace was even bigger than he imagined, and in front of the palace was a huge square platform, if he had to say it, then only the scale of the undersea city he had seen could be compared.

Looking at this huge palace, Long Xingyu unconsciously thought of the Dragon Palace, "Could this be the Dragon Palace? When he reached the vicinity of the square, he was dragged down as if he were in some kind of restraint. And when he entered the palace area, there seemed to be an invisible barrier, blocking the water from the outside, and he could not enter it.

Standing on the huge square in front of the palace, Long Xingyu felt a little depressed, "This palace is incredible, but the square in front of this palace is so big, standing in it, like a little ant, this is too hurtful to people's self-esteem." ”

Looking at the square with a radius of thousands of miles, I looked at the gate of the palace in the distance helplessly. Shaking his head, Long Xingyu still raised his feet and walked forward.
