The realm of this extraterritorial heavenly demon was only in the middle stage of returning to the void, but due to his huge size, his comprehensive combat power had also reached the realm of the late stage of returning to the void.

In the blink of an eye, this extraterritorial heavenly demon flew in front of Yang Xiaole, condensing a spatial sword and slashing at Yang Xiaole viciously.

Yang Xiaole smiled coldly and stood in place without dodging.

A muffled sound of "poof" sounded, and the spatial sword of the Extraterritorial Heavenly Demon slashed Yang Xiaole heavily, smashing him to pieces in an instant, but it turned out to be just a real phantom.

The next moment, Yang Xiaole's figure flashed out behind the Extraterritorial Heavenly Demon, condensing the World-Destroying Demon Sword and piercing the heart of the extraterritorial Heavenly Demon with a "poof".

"Whew!" The Extraterritorial Heavenly Demon let out an earth-shattering roar, and then the essence of his body was quickly sucked dry by the World Destroying Demon Sword, and he was even incinerated into ashes by the World Destroying Demon Flame, and his soul was also imprisoned by Yang Xiaole with the Nine-Layer Demon Tower.

At this time, the battle between Yang Xiaole and this extraterritorial heavenly demon also alarmed the other extraterritorial heavenly demons, and suddenly, a large number of extraterritorial heavenly demons seemed to smell the smelling flies, and they teleported and gathered here one after another.

In the blink of an eye, Yang Xiaole's up, down, left, right, and front were full of a large number of extraterritorial heavenly demons, surrounding him.

Moreover, these extraterritorial heavenly demons even cast the technique of spatial sealing, sealing the surrounding space, it seems that they have discovered that Yang Xiaole is proficient in teleportation, so they want to limit Yang Xiaole's ability.

Fortunately, Yang Xiaole is the master of this space secret realm, and he has the highest control over the space here.

I saw Yang Xiaole sneering, and suddenly a teleportation teleported out of that space seal without hindrance.

"Roar!" Seeing this, those extraterritorial heavenly demons immediately roared angrily, and then teleported towards Yang Xiaole again to chase after him.

But Yang Xiaole just pointed at it, and the teleportation of these extraterritorial heavenly demons all failed, and they all fell back to their original positions.

"Damn it, what the hell are you!" An extraterritorial heavenly demon with the strongest aura suddenly spoke.

Yang Xiaole smiled coldly and said: "I am the master of this realm, here, it is impossible for you to beat me, unless you can have the strength to return to the peak of the void and directly break this space secret realm and escape!" ”

Those Extraterritorial Heavenly Demons looked at each other, and finally the Extraterritorial Heavenly Demon with the strongest aura said, "You just killed one of our companions, you want to use his demon soul to refine magic weapons!" ”

Yang Xiaole smiled mockingly and said, "You're smart!" ”

The Extraterritorial Heavenly Demon gritted his teeth and said, "Actually, it is also good for you to keep us, we can fight for you!" ”

Yang Xiaole said lightly: "I really want to subdue you, but your demon soul is too special, and my demon sword can't completely subdue you, so I have to kill you all!" ”

The Extraterritorial Heavenly Demon gritted his teeth and said, "Actually, there is another way to completely subdue us, that is, we willingly tell you our true name, our real name is the core of our soul, as long as you master our true name, you can use special spells to control us!" ”

"Oh, tell me, what's this particular spell?" Yang Xiaole's eyes lit up and asked with interest.

"Damn, you even want me to provide myself with a spell to surrender myself!" The Extraterritorial Heavenly Demon shouted in annoyance, and finally reluctantly took out a leather scroll, wrote a spell in the words of the Demon Clan, and handed it to Yang Xiaole.

Yang Xiaole took the scroll and read it carefully.

He has language skills, and the words of the demons are not difficult for him.

Soon, Yang Xiaole learned a spell from this scroll to cast a soul brand through his true name, called the True Name Contract.

By casting a soul brand through your real name, you can completely modify the soul of the other party, even the most evil extraterritorial heavenly demons will not be spared.

Yang Xiaole was overjoyed and began to coerce these extraterritorial heavenly demons to hand over their real names and cast their real name contracts.

Although these extraterritorial heavenly demons are extremely evil and evil, they are also very greedy for life and afraid of death, after Yang Xiaole killed several extraterritorial heavenly demons in a row, but they were constantly teleported back by Yang Xiaole, and they were powerless to resist at all, they all surrendered and handed over their real names.

Soon, Yang Xiaole used the real names of these extraterritorial heavenly demons to cast a real name contract and completely controlled this extraterritorial heavenly demon army.

It's a pity that because Yang Xiaole killed many extraterritorial heavenly demons with nuclear bombs, these extraterritorial heavenly demons fought each other again during this time, and died a lot, and now there are only more than a thousand left.

And the door of space that Li Jueying left in this space secret realm, after Yang Xiaole closed it, it couldn't be opened again, it seemed that it was because Yang Xiaole's skills were insufficient, or he didn't master the spatial heavenly dao like Li Jueying.

However, with these more than 1,000 extraterritorial heavenly demons, Yang Xiaole also has an extra powerful hole card.

After subduing these extraterritorial heavenly demons and not needing to lock them in the spatial secret realm, the two spatial secret realms in Yang Xiaole's hands were a little chicken.

These two spatial secret realms were refined by consuming two World Stones and a large amount of precious materials such as space iron and top-grade spirit jade, and it would be too wasteful if they were idle.

After thinking about it for a while, Yang Xiaole decided to fuse these two spatial secret realms with the Nine Palace Immortal Mansion and the Space Prison Cage, respectively, to enhance their power.

The space cage is very convenient to trap people, but the power is gradually not enough, and the space barrier has been broken by someone.

And the Nine Palace Immortal Mansion can gather aura and quickly give birth to elixirs, but the area is limited, and the elixirs that can be planted are also limited, if Yang Xiaole integrates a spatial secret realm into it, it will be able to obtain a larger area, which can give birth to more elixirs, which is convenient for Yang Xiaole to enhance the strength of his subordinates.

So, Yang Xiaole took out the Nine Palace Immortal Mansion, the Space Prison Cage, and the two Space Secret Realms, and began to refine them.

A few days later, after repeated exploration, Yang Xiaole finally succeeded in integrating the two spatial secret realms into the Nine Palace Immortal Mansion and the Space Prison Cage.

The secret realm of space that is integrated into the space cage also hides a thousand extraterritorial heavenly demon armies, and after Yang Xiaole seals the enemies into the space cage, he can summon them out to assist him in the battle.

Unless he encounters a peerless master who is still at the peak of his prime, or a fleet composed of multiple space warships, Yang Xiaole should be able to walk sideways in this world.

However, after finding a way to subdue these extraterritorial heavenly demons, Yang Xiaole would no longer be able to use their demon souls to refine the spiritual essence, so he had to wait until the underworld, the spiritual world and other immaterial worlds to find spiritual essence.

At this time, the Flying Rain finally carried Yang Xiaole to the vicinity of Tianxin Star, where the headquarters of the Universe Alliance was located.

But at this moment, a large spaceship suddenly burst out of subspace and slammed into the Raindance viciously.
