When Fatian and the others saw the colorful light defensive barrier, a very obvious curiosity appeared in their eyes.

The King of Abyss: "The defensive power of the colorful light defensive barrier around the space black hole is obviously very strong, and the defensive power of the defensive barrier in the alien space is obviously also very strong. This cannot be condensed by the defensive formation by condensing the power of heaven and earth. Moreover, the alien space in front of us is so small that it is impossible to arrange a formation that condenses powerful energy."

Tang Long also felt that there should be some secrets hidden in this alien space.

At this time, dozens of peak demon emperors had already rushed towards them around them, and there were even a few ancient demon emperors whose combat power had reached the primary level of Tianzu. Moreover, in the space black hole protected by the colorful light barrier at the high altitude, peak demon emperors kept rushing out.

Fatian and the others didn't even take these peak demon emperors at all.

The peak demon emperors cannot reach the combat power of the Tianzu at all, but are just some monsters with the primary and intermediate combat power of the Earth Ancestors. Fatian and others can easily deal with it.

Together, they kept bombarding the peak demon emperors rushing over around them.

Xuanyuan Tian Formation turned around in this alien space and looked around, then looked at Tang Long and said, "Tang Long, the defensive barrier that supports this alien space and the space gate, and the defensive barrier that protects the space black hole. This is obviously a barrier condensed by the same defensive formation, and this formation must have a very powerful source of energy."

Fatian also turned around and looked around. He saw mysterious black runes flashing in the black hole in the space at high altitude. Looking at the colorful light defensive barrier, he soon discovered something.

He looked at Tang Long and said, "The defensive formation arranged here is extremely profound, but I think it seems to be similar to the formation in the hall in Wangu Cave that stores the energy source!"

Tang Long hurriedly said, "Since that's the case, the King of the Abyss and I will resist the attacks of these peak demon emperors. Xuanyuan Tian Formation, you and Fatian, you are responsible for finding this energy source here!"

"It's good!"

Both Fatian and Xuanyuan Tian Formation agree with Tang Long's arrangement.

With the King of the Abyss and the others, they can already block the attack of the peak demon emperor here. Fatian and the others began to work hard to find the space formation here to find the source of energy hidden here.

Tang Long hopes to find the energy source as soon as possible and then destroy the space black hole in the sky as soon as possible.

If this space black hole continues to exist, who knows if the Crown Demon Emperor will come out again later?

Not to mention the Crown Demon Emperor, even if the ancient Demon Emperor rushed out, it would be difficult to deal with.

Fatian and the others tried to check the situation in the surrounding space, explore the continuous surging energy between the world, and then explore the situation of the defense barrier of the black hole in the space at high altitude, and look for some secrets hidden here.

They spent almost two hours like this, used various means, and finally found where the source of energy was hidden.

This formation with the source of energy is actually very similar to the one they discovered when they were in Wangu Cave, but this hidden formation seems more profound.

If they had no previous experience at Wangu Cave, even if Fatian and his friends had a higher attainment in formation, it would be difficult for them to find the place where the energy source is hidden in such a short time.

After finding where the source of energy is hidden, it will be simple next.

There is obviously no attack formation in this alien space. Once the energy source is cancelled, the energy barrier supporting the space black hole in the high altitude will disappear immediately, and the space black hole will collapse directly.

The collapse of the space black hole will cause great destructive power, which is enough to destroy this entire alien space.

Moreover, the dark space gate will be completely destroyed in an instant! The Fatian and Xuanyuan Tian Formation are already accurate. They are about to open a small space gate and take out the source of energy. At this time, they are all very nervous.

The sky has already begun to be busy.

He closed his hands and quickly changed his handprints.

Five minutes later, in the air above fifty meters ahead of him, the space there suddenly became a slight twist, and the twist gradually became more and more obvious.

Obviously, there is a space gate of different dimensions there, and this space gate is about to be opened.

Xuanyuan Tian Formation said in a deep voice: "We are going to return to Tang Long's Tianfeng Banner. Tang Long, go to the dark space gate to prepare. Wait for a moment when the energy source flies out and the space black hole collapses, you must leave the dark space gate immediately. If you stay for a while, you will be completely shattered by the space turbulence! Tang Long of course also knew that the situation was serious at this time. He and the King of Abyss, he drove the peak demon kings who rushed over, while moving towards the dark space gate.

But at this moment, just as they moved towards the dark space gate as soon as possible, an extremely terrifying roar suddenly came from the space black hole in the sky.

Then an extremely terrifying blasting force contained a powerful momentum, and it swept out from the black hole in the space! "Oh no, it's the Crown Demon Emperor!"

Tang Long was extremely shocked! He didn't expect that at this time, a powerful crown demon emperor would appear again.

He didn't care about it and hurriedly concentrated his energy with all his might and flew towards the dark space gate.

Fatian and the others were also shocked.

They dared not hesitate at all. They didn't have time to see if Tang Long and the others were ready to leave, and opened the space door with the source of energy as quickly as possible.

As soon as the door of this space opened, a dazzling colorful light burst out, and then a colorful light filled with terrifying energy! "Boom..." At this moment, the entire alien space suddenly shook violently.

Around the black hole in the space at high altitude, the defensive barrier of colorful light has made continuous "cracks" shattering sounds.

In this shattering, one head was extremely ferocious and had two heads, the Crown Demon Emperor had already poked his head out of the black hole in the space, and his blood-red eyes had fallen on Tang Long and the others! "Go away!"

Tang Long shouted loudly and hurriedly flew towards the dark space gate. The sky condensed its vitality and wrapped the energy source of the colorful light. Then, together with the Xuanyuan Tian Formation, it turned into a ray of light and merged into Tang Long's body and returned to Tang Long's Tianqi Banner.

The King of the Abyss and the others hurried back to Tang Long's Tianfeng Banner.

Tang Long rushed out of the dark space gate.

He had just rushed out of the space gate when he heard a thunder explosion coming from behind. The explosion was extremely powerful and directly shattered the dark space gate.

Even, where the Space Gate exploded, the space there was directly bombarded with a dark hole of more than 100 meters.

In this dark cave, crazy space turbulence swept out, bombarding Tang Long with thousands of meters.
