But then again, now that Niu Gao was by his side, Xun Tian was not worried about encountering immortal-level creatures again and would not be able to deal with them.

The two then explored in the huge space, and both Niu Gao and Xun Tian also gained a lot.

It wasn't until millions of years later that Xun Tian raised his cultivation to the pinnacle level of the Realm Emperor Realm.

However, he also knew very well that it was almost impossible to break through to the Realm Emperor Realm in a short period of time, unless he could obtain a large amount of cultivation resources.

Suddenly, Niu Gao's cultivation realm broke through to the immortal level.

Naturally, he was also elated.

But it also meant that he was about to leave the space.

Having reached the immortal level, it was naturally easy for him to leave this space.

Of course, if Xun Tian hadn't brought him into this space, he would probably have been difficult to break through to the immortal level.

Niu Gao then said to Xun Tian: "I'm leaving, now the space-time gate needs me, take care of yourself in the future." ”

After the words fell, he broke through the air.

Xun Tian saw him leave quickly, and his heart was slightly shocked.

But then he began to become cautious because he lost Niu Gao's support, after all, he had encountered many immortal creatures over the years.

Exploring in the space little by little, Xun Tian also knew very well that he had probably only explored the tip of the iceberg of space so far.

I have to say that the cultivation resources in this space are indeed very rich, and he has also benefited a lot from it.

It's just that when he thinks about his own training, he still feels a little depressed.

After thinking about it, he still felt that it was not worth it to continue the adventure, so it was better to retreat.

After all, I am not afraid of running out of firewood.

As long as he is alive, then everything is well said.

After a long time, Xun Tian returned along the same path.

Luckily, he didn't encounter immortal-level creatures along the way.

Eventually, he exited the space and returned to the outside of the spatial vortex.

Looking around, he found that there was a vast void all around, but Xun Tian gradually relaxed his vigilance.

Naturally, he knew very well that the outside world must be safe.

Because if there was a powerful existence at the immortal level, I am afraid that it would have been killed by Niu Gao a long time ago.

Of course, immortal-level creatures are also strong and weak.

According to the contents recorded in the notes of the Demon Codex, Xun Tian had already understood that the cultivation realm of the immortal level was divided into the Creator, the Creator, the Lord of the Universe, and the Lord of Nothingness from low to high.

Although there are only these four layers of cultivation realm at the immortal level, it is conceivable that it is not so easy to break through to any of the cultivation realms.

In fact, in the void space, the vast majority of immortal level cultivators basically stayed at the creator level.

Now Niu Gao has broken through to the creator, and from then on, hundreds of millions of time and space can basically come and go freely.

Although Xun Tian could currently do this with the Shadow Space-Time Skill, his fear of immortality still made him fearful.

In addition, he also knew very well that in order to step into the immortal level, he had to convert all the realm elements in his body into cosmic true elements.

If the sign for a cultivator to step into the Domination Level is to transform all the energy in his body into Realm Elements, then the sign of entering the Immortal Level is to retransform all of these Realm Elements, thus forming a unique Universe True Element.

In fact, the countless cosmic true elements in the immortal body can be said to be miniature space-time, and at the same time, it is also equivalent to tiny cells in the physical body.

The countless realm elements that exist in Xun Tian's body today are miniature spaces.

However, even any micro-space is equivalent to the size of a micro-universe.

As long as Xun Tian is willing, he can create a lot of powerful level intelligent life in these miniature spaces.

Of course, this inevitably requires a lot of energy.

Sometimes, Xun Tian even thinks that nothingness itself is a kind of intelligent life.

It can be infinitely large or infinitely small.

However, only when it is infinitely small, it is possible for an immortal-level cultivator living in the void space to reach the edge of the void space, otherwise the void space that is in a state of constant expansion at the moment will always make the cultivator feel at a loss.

So far, in Xun Tian's cognition, except for the owner of the lava sword scabbard, he has not seen any powerful life that exists outside the void space.

It didn't take long for him to explore and perceive around, and then he spotted a group of Void Beasts that had traveled through space.

Normally, Void Beasts would carry the universe through the void, as if that was their mission.

However, the group of void beasts Xun Tian saw now was empty on their backs.

So, he swung his sword and harvested them one by one.

After all, although these Void Beasts were in the same cultivation realm as him, they could still bring some cultivation realm improvement to all the cultivators in the space in his body.

After killing and collecting all the Void Beasts, Xun Tian was ready to explore again.

At this time, a group of masked black-clothed men suddenly broke into his divine vision.

Seeing this, Xun Tian was moved.

It seems that the Star Thief Hall has still been found.

However, after some inspection, he found that the group of masked men in black may have entered the space by accident.

Therefore, he hesitated whether to kill them or not, after all, he knew very well that immortal level cultivators could view everything that had happened in the past at will.

If he killed this group of cultivators, then he would inevitably need to leave this space quickly, and he would have to remain invisible all the way through, not being able to reveal any traces.

Under the turn of his mind, Xun Tian thought that since the masked men in black had already come here, it was not appropriate to stay here for a long time, so why not kill these masked men in black before leaving here?

It may leave clues as a result, but so what?

As a result, he immediately transformed into a lava sword, and wiped out the masked man in black with three strikes and five divisions.

Not only that, but he also properly disposed of all their corpses, turning them into a state of energy and storing them in the space in their bodies.

In his opinion, perhaps this is the only way to be foolproof.

However, not long after he left this place, he suddenly came here with the help of a space-time portal.

Naturally, he was always on the lookout for any movement of the masked man in black.

When he saw that the masked black-clothed man in this void suddenly disappeared, and this was probably the work of the cultivators in the space-time gate.

Therefore, he decisively erased all the things that happened in the past in this space, and this could not only ensure the personal safety of the cultivators in the space-time gate, so that they would not be tracked, but also prevent the various strongholds of the space-time gate from being exposed.

After all, as long as they are members of the space-time gate, they always have to return to the space-time gate, and during this period of time, all the members of the space-time gate are also cautious to avoid letting the Star Thief Hall take advantage of the loophole.

Now that the Star Thief and the Space-Time Gate are in a truce, Nightmares are still everywhere.

They basically serve as assassination missions, and are far stronger than the killers and scouts sent by the Temple of Thieves.

Many members of the Space-Time Gate were unknowingly damaged by the Nightmare's hands during this period of time, which caused a headache for the high-level members of the Gate.
