After entering the range of forty miles, the yellow Wutu God Thunder came as scheduled, slashing at him fiercely, although he had seen it many times, but when he saw this God Thunder again, Nie Yuntian's heart still couldn't help but rise in awe, and sighed how small and powerless he was under the power of this vast heaven and earth.

As he went deeper, the Lei Fa in the dojo space became more and more powerful, and the intersection of the two teams of wandering spirits was also very frequent, and every time he didn't walk long, he had to hide back in the small world and wait for them to pass before coming out to continue his journey, but fortunately, in addition to the geist and Lei Fa, other dangers were not enough to stop him, and after about an hour, Nie Yuntian came to the junction of thirty miles.

This is the place where he is going to dig the tunnel, and he can't bear the deep thunder method, so he digs here for the sake of safety.

After selecting the location, Nie Yuntian took out a shovel, which was made by a magic weapon broadsword, ordinary shovels could not withstand his ravages, not only shovels, but also a lot of digging tools while waiting before, pickaxes and hoes.

Digging tunnels is destined to be a long and arduous task, so how can you not prepare?

Removing the rubble from the surface revealed the reddish-brown soil underneath, which looked like normal soil, but it was so hard that even he had to dig with five percent of his strength, but fortunately he was able to dig it so that his plan to dig the tunnel could continue.

After more than half an hour, a hole more than three feet deep into the ground was dug, and now all that had to be done was to dig deeper into the space of the dojo.

Half a day later, at the end of the tunnel, under the bright white light of the illuminating stone, Nie Yuntian waved his pickaxe to dig down the soil and stones in front of him, while Ming Yuexia, who followed him, put the soil and stones he dug up into a storage bag, and when they were all full, they were brought back to the small world to be disposed of.

With the cooperation of the two, only half a day's work was excavated into more than 30 zhang, the efficiency is very good, all-weather excavation only takes a month to dig to the center, even if only digging the day shift, two months of hard work will be dug through.

Compared to that huge gain, two months is not worth mentioning at all, even if there is still a chance to go out now, he will take the initiative to stay, and it is definitely a very cost-effective transaction to exchange an inch for three years in exchange for rare treasures in the dojo space.

Suddenly, Nie Yuntian, who was digging vigorously, suddenly shuddered, his heart beat heavily, and there was an inexplicable depression in the air around him, and the blood spirit crystal also sent an extremely dangerous signal at this time!

Nie Yuntian was shocked, hurriedly threw away the pickaxe, picked up the unknown Mingyuexia and staggered back to the small world.

"Whew-"

As soon as Nie Yuntian flashed back into the small world, he felt a fierce wind blowing, and the pickaxe and shovel still left in the tunnel quickly rotted, and it didn't take long for it to rust into slag, no different from dirt.

The illuminating stones on the walls of the tunnel also quickly dimmed in the gloomy wind, and after a while, the entire tunnel became pitch black and fell silent again.

However, Nie Yuntian still saw something at the moment when the light disappeared, a geist that came out of the wall.

This geist is different from the white geist on the ground, his entire soul body is purple, and his body also bursts out from time to time with electric sparks, and the soul body is much taller and clearer than the geist on the ground, holding a soul-transformed spear, very powerful, especially his eyes, as if they have a spirit shining with strange brilliance.

"Soul General!"

Nie Yuntian exclaimed in his heart, he didn't expect that there would be a soul general among the spirits here, this level of spirit can only be formed after the death of a Spirit Tribulation Realm cultivator, and it itself at least retains the strength of the Psychic Realm.

Compared with ordinary geistes, in addition to their stronger strength, the soul generals also have the ability to void, that is, they can travel through hard solids, which is also the reason why Nie Yuntian has dug the tunnel for a long time and there are no ordinary geists to disturb him, as long as the entrance is blocked, they can't enter.

Originally, he was still strange, even he could think of digging a tunnel to avoid the ghost and thunder method on the ground, it was impossible for the ancestor monks of the Xuanling Sect not to think about it, but he did not use this method to develop the central forbidden place of his dojo space, but now he finally understood, it turned out that there was an even more powerful soul general-level ghost patrol underground!

In this way, in the forbidden land in the center of the dojo space, I am afraid that there is a soul handsome-level wandering soul equivalent to a cultivator of the Spirit Tribulation Realm!

But fortunately, the blood spirit crystal can also play an early warning role, even if the soul general-level wandering soul has the strength of the psychic realm, it is only the primordial god who has been dead for an unknown amount of time, and his own intelligence is extremely limited, otherwise even if he has the blood spirit crystal, it is impossible for him to escape from the hands of a real psychic realm monk, they often can make his soul fly away with a single thought, where is the chance to escape?

After a long while, the cold feeling finally disappeared, and after waiting for a while and still not moving, Nie Yuntian came out of the small world and took out another set of tools to continue digging, since it was decided, there was no reason to give up.

However, he didn't call Ming Yuexia to help him, although it was a lot slower, but he didn't have any scruples, even if he encountered a ghost again, it would be convenient for him to escape by himself.

Sure enough, half a day later, Nie Yuntian met another soul general, different from the last time, this was a phoenix bird, a wandering soul formed by a demon spirit after the death of an eighth-order demon beast.

Its arrival caused Nie Yuntian to lose another set of excavation tools, but fortunately, a few days ago, a lot of magic weapons were seized, and the loss of one or two sets was not taken to heart.

However, after half a month, Nie Yuntian had to carefully protect his excavation tools, these days, those souls will haunt from time to time and have no regularity at all, often you can encounter more in a day, and there are no repeats!

In other words, the soul generals in the dojo space are not a small number, these wandering souls were cultivators of the Spirit Realm before they were alive, but now there are so many, which shows how terrifying the power of the Tianya Dao Sect was at the beginning.

Compared to the loss of excavation tools, Nie Yuntian was even more speechless but helpless What was the speed of this excavation, without Ming Yuexia's assistance to him, the speed was already a lot slower, and now there is a soul in the future, it would be good to be able to dig twenty zhang a day, and if it goes on like this, it will not be able to dig the center of the dojo space for a year and a half.

"Hey!"

Nie Yuntian sighed lightly, and continued to dig again, a year of hard work is not too long, as long as it is not more than three years, it is enough, it should be regarded as tempering his spiritual power.

Took out a small piece of lighting stone and embedded it in the wall, but now it can only be used sparingly, and Nie Yuntian continued to dig with the dim light.

About half an hour later, the Blood Spirit Crystal came another warning, Nie Yuntian picked up the pickaxe and quickly hid back in the small world, after so many times, he had already reached the point where practice makes perfect, that is, he could ensure his own safety and bring back the digging tools.

A strange humanoid soul will float by, looking at the unscrupulous appearance Nie Yuntian can't wait to jump out and give him a fat beating: Tell you to bother me!

However, reason told him that going out was definitely an act of looking for death, and he could only secretly scold him in his heart.

After the soul general left, Nie Yuntian jumped out again, well, the general style of guerrilla warfare.

He was about to start work, but Nie Yuntian suddenly remembered something, and looked at the tunnel behind him, where the two lighting stones emitted a faint light, making the tunnel deep underground not so dark.

"Two pieces?!"

He remembered that he had placed three small Illumination Stones before, but now two of them were still bright, shouldn't they all decay under the Yin Wind of the Soul General?

The soul general, that is the spirit of the psychic realm, the yin wind that overflows from its body alone is not something that ordinary items such as lighting stones can withstand, and it often turns into scum when it blows.

None of the souls he encountered before had decayed into slag that he had too late to bring back to the small world, but now he only decayed one piece and left two pieces, what is the matter?

Could it be that he was afraid that he would not have enough lighting stones, so he deliberately left it behind?

"There must be a demon when things go wrong! There is definitely a problem here!"

With doubts, Nie Yuntian took some magic weapon spirit stones and scattered them in the tunnel, and the bright treasure light illuminated this section of the tunnel in a trance, so it was not dazzling.

Then Nie Yuntian returned to the small world and waited for the soul general to come and see what was going on.

Half an hour later, accompanied by gusts of yin wind, a huge wolf-shaped soul will come here, the peripheral spirit stone magic weapon quickly decayed under its yin wind, and the items on the inner side naturally did not change under the yin wind, and still maintained their own light.

The wolf-shaped soul would only need to take one step towards this side, and its yin wind could envelop the remaining items, but it didn't, and after glancing at this side, it disappeared into the wall on the other side, disappearing from Nie Yuntian's sight.

"Fear...... I actually saw fear in its eyes?!"

Nie Yuntian exclaimed incredibly, he was very sure and sure that it was a look of fear, there was actually something on his own territory that made it, the immortal and immortal soul of the psychic realm, fearful?

As if he couldn't believe this result, Nie Yuntian tried a few more times, but each soul general left after decaying the east side outside the second illuminating stone, and everyone invariably left a look of fear, as if it was a thunder pool, and once it was crossed, it would suffer an irreversible catastrophe!

"This ...... Seems to ......"

Nie Yuntian racked his brains and couldn't think of anything that could make them so afraid,
