At the same time, with no more energy to absorb, it finally unleashed a powerful, long-awaited attack.

Sure enough, an anomaly appeared above the pool, with spatial ripples spreading out of thin air, as if something was being torn apart with great difficulty.

That feeling of difficulty seemed to bring forth a hissing sound of spatial forces rubbing together.

It not only tortures the ears but also damages the mind, leaving one feeling disoriented.

Fortunately, Liu Yun quickly added several layers of defense to her three companions and even spread her wings, ready to maximize both magical and physical defense at any time.

Zhang Linyuan also activated his spatial defenses, enveloping his entire group within them.

Since his spatial abilities are so useful, using them for defense would definitely increase the chances of success.

As it turns out, Liu Yun's willingness to leave her side behind instead of letting the two leave first demonstrates her confidence in the defense.

The steel wings had given her a lot of confidence before.

Furthermore, this was not an attack from the true form of the angel, but rather an unconscious barrage from the portal.

Moreover, Liu Yun discovered that the spatial gate was right above the pool of water, so she immediately retreated outside the barrier. In any case, the barrier set up by the angels was the first line of defense.

Now it's their turn to be protected.

The right way is to make use of everything that is available.

In just a few minutes, a small black dot seemed to appear in the middle of the ripples. Under the invisible pull of a powerful force, the small dot kept growing larger.

From the initial size of a Go stone, it grew to the size of a ping-pong ball, then to the size of a bowl, a plate, and a volleyball...

The portal to space is indeed opening.

Liu Yun was also a little nervous. She could feel the violent power inside and around her, which was indeed beyond her control.

Fortunately, no one was arrogant enough to try and stop it.

However, just because you can't stop it doesn't mean you can't cause damage!

Liu Yun took out a handful of small round balls and tentatively threw them towards the black hole.

Most of them were swallowed up silently.

A small portion of it was detonated by the force at the cave entrance, but the power was not too great.

A very small number of them exploded inside the black hole; the sound could still be heard, suggesting that they weren't too far from the entrance.

The energy inside the main cave is extremely unstable and carries a violent quality; it's impossible to predict what will happen to anything thrown in.

However, she didn't need to anticipate anything; an explosion inside the cave would be enough, only making the energy within the cave more chaotic and unpredictable.

The more unpredictable something is, the more difficult it becomes for the other party to open the portal.

Even though the chance of an explosion was very small, Liu Yun didn't care. She just threw handfuls of small balls at a time and listened to the sporadic explosions that occurred inside.

If you keep playing like this, even if the odds are small, you'll eventually get lucky.

Just as the black hole grew to the size of a basketball, something crucial was blown up, seemingly triggering a chain of explosions.

After the first bang, a series of booming sounds followed, along with rolling thunder-like sounds that continued as one ran.

Liu Yun was stunned by the mechanical motion of throwing the small ball.

Then, the chaotic spatial energy inside the cave seemed to be squeezed out by some force, surging into this world and causing a huge storm that blew sand and stones flying everywhere, with everything flying in the air.

Apart from Liu Yun and the other two.

However, they didn't expect that after taking various precautions, they would also have to guard against being blown away.

They frantically gripped the ground deep inside, which prevented it from being flown like a kite.

Under these circumstances, the black opening seemed to become visibly unstable, changing from a circle into various irregular shapes.

At the same time, they seemed to hear several roars, which sounded distant but were still clear.

"Damn it, what happened?"

"Impossible. The markers in that world were chosen carefully, in the most stable location, and angels sacrificed themselves to become the landing points that opened up space. How could it be so unstable?"

Were all those angels who went before blind?

"Such a serious situation, how could they not have noticed at all?"

"Oh no, we can't hold on any longer! We've run out of supplies, we need to add more..."

"This would result in huge losses for us."

"Then what should we do? Give up? Then all the previous efforts will have been in vain."

"..."

Hearing the noisy argument, Liu Yun felt that even the sound of the raging wind was much more pleasant.

Yes, so much has already been wasted.

If we stop now, won't we lose everything?

The plan also failed.

"Hurry up and add more!" Liu Yun chuckled, continuing to use her internal energy to wrap the small sphere and send it into the black hole.

It may have already caused adverse reactions; the explosion of the small sphere is increasingly affecting the interior.

The circular opening seems to be increasingly unable to take shape.

Another angry roar came from inside.

"Keep deploying. This can't fail, otherwise the marker in that world will disappear, and we'll never be able to lock onto it again."

Upon hearing this, Liu Yun and the other two's eyes lit up.

Great, that's exactly the effect I wanted.

If this sabotage succeeds, the other party will lose its connection to this world, which would be perfect.

Liu Yun suddenly realized what the ultimate purpose of Heaven had brought her here.

Perhaps it is right now.

When those angels returned, they must have left a mark. That world found this world by following the mark, wanting to control it.

Now, everything can be over.

"No, the power of darkness? Why would there be the power of darkness?" The roar seemed filled with disbelief.

"Oh no, retreat quickly..."
