The small world of the Demon Spirit Crystal Essence was six thousand miles in circumference, and even if there were any important items, most of them were in the center of the circle, and it was almost nearly three thousand miles from here to the center of the circle, and even if he was to rush at full speed, it would take several days.

Moreover, there is no direction to speak of, and I don't know which direction leads to the center, and if you get it wrong and go astray, it's not fun. However, this is not difficult for Nie Yuntian, after carefully observing the distribution and growth of the surrounding grasses, Nie Yuntian identified a direction and galloped away.

This is actually very simple, in many places, the position of the center of the circle is more important, and this small world must be the same.

In ancient times, the cultivation of the corpse buried in the center of the small world by the Xuan Immortal must be higher than that buried in the periphery, and in the case of more nutrients, the amount of living grass will also be more.

Up to now, there are more remnants of aura in the land closer to the center, and the growth of the living grass is also better.

Under the radiation of the aura, the farther you go to the periphery, the more scarce the aura becomes, and the growth of the living grass is naturally poor, so Nie Yuntian can judge the direction according to the density and growth of the living grass.

Sure enough, as Nie Yuntian continued to go deeper, the vigorous grass he encountered on the road became more and more "dense", and the plant form became more and more full and green.

About an hour later, after the spiritual power in the dantian was completely consumed, Nie Yuntian stopped. With the assistance and blessing of physical strength and spiritual power, he traveled four or five hundred miles in an hour! It was faster than the full strength of the peak of the Convergence Spirit Realm, and the staying power was not as long as his, he valued speed very much, even if he couldn't win, he had to escape and win.

After stopping, Nie Yuntian began to use the spirit stone to restore his aura. Another hour, after consuming more than twenty fast spirit stones, he filled the spiritual energy in the dantian, and after careful inspection, the spiritual energy points increased a little, and the strength of his physical body also increased a little, and most importantly, his spiritual power was refined again!

This discovery made Nie Yuntian overjoyed, he didn't expect that someone would send a pillow as soon as he fell asleep! Although the speed of refining this method is relatively slow, it is what he can achieve now.

Nie Yuntian looked ahead, and the plain was still as wide and silent as it had been at the beginning.

I thought it was a boring journey, but I accidentally found a way to store spiritual power, and I could cultivate while I was in a hurry, Nie Yuntian felt that this was very sour and suitable for him.

After recovering, Nie Yuntian set off again, this time he squandered his aura more unscrupulously, and did not use it sparingly as the first time, and the result of this was that after only traveling more than three hundred miles, his aura was consumed again.

However, Nie Yuntian didn't care much, anyway, what he had was a spirit stone, which was enough for his expenses.

……

Half a day later, Nie Yuntian had already walked about half the way, and he was now cross-legged on a clearing to regain his aura.

After replenishing the aura again, Nie Yuntian got up again and headed towards the center.

He had not encountered the slightest danger along the way, which greatly relaxed his vigilance, and he almost regarded this expedition as an ordinary outing, indescribably leisurely.

After a while, however, he had to be wary of it, for he had discovered a special circumstance.

After walking for more than three hundred miles, when he was about to stop to recover his aura, he suddenly found that a piece had collapsed not far from the left front, forming a ravine, which was very conspicuous on this wide and flat plain.

Nie Yuntian was stunned for a moment, thinking that he had arrived at the center, but he did not rush over, but sat down cross-legged again and recovered his aura, he wanted to restore his strength to the best state, only in this way could he deal with all kinds of emergencies.

An hour later, Nie Yuntian headed towards the ravine, and after a while, he came to the edge of the ravine.

At this time, Nie Yuntian discovered that this should be a river channel, a river left after the river dried up.

This river channel is nearly 100 zhang wide and dozens of zhang deep, and the dry brown riverbed is covered with emerald green grass, which looks very strange.

Nie Yuntian looked at this river channel and was silent for a long time, this should not be an ordinary river, it may be a river formed by blood!

A river of blood!

The rushing blood flowed forward, what a terrifying and bloody picture.

After returning to his senses and looking at this river, Nie Yuntian's heart moved, looking at the direction of this river, this river may be flowing to the center of the small world, thinking of this, Nie Yuntian continued to follow the river towards the center of the small world.

After another half a day like this, an area suddenly vacated on the land in front of Nie Yuntian, and there was not a single living grass in sight.

Nie Yuntian was overjoyed, thinking that he had arrived in the center, and hurriedly galloped over.

When he got there, Nie Yuntian found that Najing was a pit, a big pit nearly 10,000 zhang square, I don't know how deep it was, there was nothing on the dark brown pit wall, only a little fluorescence at the bottom of the pit, but it was too far away to see what it was.

And the river he walked along was flowing to this huge pit, and it is conceivable that it must have been filled with blood and water at the original time, and I don't know what the reason was, it dried up.

And there is not only one river in the small world, he saw many river mouths around the pit, and he did not know how many there were.

"I guess the biggest secret of the Evil Spirit Crystal is at the bottom of that pit. ”

Nie Yuntian looked at the fluorescent and secretly thought that when he came to the edge of the huge pit, the wall of the pit was not so steep, he took out the dagger, held it tightly in his hand, and then jumped into the giant pit and slid towards the bottom of the pit.

At this time, Nie Yuntian found that the soil here was not as dry as he had encountered before, but slightly wet, and the deeper he went, the more so, which confirmed his conjecture.

At this time, an extremely strong smell of blood suddenly wafted into Nie Yuntian's nose, making his steps abrupt.

Reaching out and touching the ground, a very viscous feeling was transmitted, and when I took it in front of my eyes, it was black blood!

If he hadn't experienced a river of blood in his dream earlier, and now he was facing a bloody situation, he might have fainted with fright, but he was still so frightened that Nie Yuntian's face turned pale.

Due to the mud formed by blood and dirt, and the fact that he was relatively heavy, his movement was very inconvenient, but fortunately the mud was not too thick, otherwise he might have fallen into it.

Continuing to go deeper, the fluorescence became brighter and brighter, and when I reached the center, through the fluorescence, I saw that the bottom of this huge pit was indeed a bloody field, but it was only a few tens of zhang in size, and the strong smell of blood came from this blood pool.

There was a huge blood-colored lotus flower in the center of the blood pool, and those fluorescences were floating on the blood-colored lotus.

This fluorescence is also several zhang in size, and is composed of some smaller fluorescences, through which a figure can be faintly seen sitting on the blood-colored lotus.

Seeing that figure, although Nie Yuntian didn't make any moves on the surface, his heart turned up a huge wave.

"This ...... What's going on?!How can there be people here!!"

Nie Yuntian was frightened, if there was really someone here, it could only be the Blood Dao Xuan Immortal!

Thinking of this, Nie Yuntian suddenly wanted to go out, but the usual method of trying a hundred souls failed, and he still stayed where he was! At this time, his face was ugly, it could be said that his face was like ashes, and he said secretly: "Am I going to die here today?"

After observing along the way, Nie Yuntian already knew a little bit about the temperament of the Blood Dao Xuan Immortal Dao, that is, a demon who kills people without blinking!

In the face of the food delivered to your door, how can you let it go?

Nie Yuntian also regretted it very much, regretting that he shouldn't have come down so easily, how could he have come down after finding out the situation.

However, just when Nie Yuntian was thinking about what he would do with that Xuan Immortal, he saw that the figure was still sitting cross-legged on the lotus flower, and he didn't make any moves.

"Uh......"

Nie Yuntian was stunned, not knowing what to do, and suddenly, he remembered that the Earth Heavenly Dao had said that the Spirit Crystal Essence had the effect of cultivating the spirit.

"Could it be that this is just the remnant soul of that Xuan Immortal?!"

Nie Yuntian exclaimed, thinking that the Heavenly Tribulation was not so unkind, leaving him a glimmer of life, so that this wisp of remnant soul remained.

The more Nie Yuntian thought about it, the more he felt that this was the case, but if it was a remnant soul, he was not so afraid, even if the heavenly tribulation left him a glimmer of life, this remnant soul was probably not far from the soul flying. (To be continued)
