Soya did not obey the ashes' opinions, but took out a long hook rope from her backpack and fixed the hook claws at one end to the edge of the rift.

"You can go down with me or choose to stay on it." Soya said to Ashes.

"Then I'll go down with you."

Without Soya's protection, staying on it would be even more dangerous for the ashes.

...

The two of them used the hook rope to get into the rift, one by one, and one behind, and began to move towards the central area of ​​the rift.

The plants inside the rift are very lush, and Soya must constantly wave the sharp blade in her hand to barely open up a path that can be passed by.

During these decades, it was not without survivors who thought about cleaning up the rift valley completely. They even found a large amount of black stone and tinder oil, trying to burn all the plants in the rift valley. However, due to the special terrain environment, the air humidity inside the rift valley is very high. Even if there is no plague fog, the rift valley is filled with humid fog all year round.

Logically speaking, the miasma produced by the rotten corpses of a large number of animals and plants should be very flammable and even detonated by open flames. However, the gas in the rift is different and cannot be ignited at all. The survivors consumed a kilogram of black stone and several jars of tinder oil, and only cleared a small piece of open space.

"Have you discovered something?" After walking more than ten meters in the Rift Valley, Ash suddenly spoke.

"Um?"

"The flow rate of fog has accelerated... and the rotation angle is very regular...it is like..."

"It's like a vortex." Soya said directly what the Ashes thought.

"As for Edward's description, the area of ​​the black fog at the beginning did not cover the entire palace area, but now, not only is the entire palace area in black fog, but the black fog continues to spread, as if something is constantly creating black fog." This scene made Ash think of a device that is often used on the theater stage. The body of the thing is a blower powered by steam. However, as long as dry ice is mixed with some chemical reagents and placed behind the air outlet, the entire stage will soon be covered by white fog. If dry ice is constantly replenished, the white fog can even fill the entire theater.

The volume of the black fog has expanded dozens of times compared to the beginning, but the concentration has not decreased - this is different from the plague fog that has appeared before. The spreading area of ​​the plague fog has never reached such an exaggerated level before. The only thing that is crazyly infected is the plague virus, not the plague fog itself.

"You mean something is creating black fog inside?"

It is absolutely unscientific to expand out of thin air... Two hundred years ago, the "phlogistin theory" proposed by alchemists was overthrown by people, and the new "law of conservation" has become one of the world's recognized physical truths. According to the content of the "law of conservation", in an independent "system", the total mass of any matter cannot increase out of thin air. If there is a change, there must be other matter converted into this substance.

To put it simply, it is... "One rises and the other falls".

When the black fog can continue to spread, new substances must be constantly replenished, and this replenishment process is still going on.

"Yes... Black Fog..." Ashes wanted to say something, but when he saw the strange scene ahead, he found that his throat instantly became extremely dry and could not make any sound...

It was indeed a vortex, a black vortex hanging about three meters above the ground. A large amount of solid black mist was constantly being spit out from the center of the vortex, and at the center of the vortex, it was completely pitch black... This black is absolutely pure black, and it seemed that even the light scattered by the steam lamp could not escape from it.

It is precisely because of this reason that Ash and Soya discovered this strange vortex more than ten meters away.

"It's a singularity." Soya said biting her lips, her breathing seemed to have become much heavier.

"What is a singularity??" Ash certainly knows what "singularity" means. In mathematical theory, singularity represents a point that has not yet been defined in a mathematical object, and in geometry, any independent endpoint can be regarded as a singularity... But it is obvious that the vortex in front of you and the "singularity" at the mathematical level are not the same concept at all...

"That is a special spatial coordinate. On this spatial coordinate, the space will fold in an extremely incredible way, and can even connect two places thousands of miles apart... According to scholars' inferences, the blazing white light column that appeared on the day of arrival is likely to reach the target through the singularity." Soya explained, her voice was very light, as if she was afraid of disturbing the "singularity" not far away.

"Then... the other end of the singularity... is DiPest's... real body?"

"I don't know... In fact, no one has ever seen a singularity with his own eyes." Soya shook her head gently, and then took a tentative step forward...

At this moment, the direction of the rotation of the vortex composed of black mist suddenly turned, and the black mist that had been constantly spewing out quickly gathered towards the position of the singularity. Soya was instantly captured by the huge attraction released from the singularity and began to drag her into the singularity!

A trace of fear flashed in her eyes, and then, the horsepower of the power armor was suddenly increased by her to the point of collapse... However, the large amount of steam gushing out of the exhaust hole was all sucked into the singularity before it even left the armor more than one centimeter. No matter how Soya struggled, the distance between her and the singularity was still shrinking!

Her posture has changed from standing to lying down, trying to use this method to gain more grip. Under the pull of the invisible force, she plowed a deep gully on the ground...

Ashes were completely stunned. A huge sense of fear spewed out from the depths of his brain, completely swallowing his thoughts. He subconsciously took two steps back and fell to the ground.

He did not feel the terrible traction at all. The gravitational field around the singular point seemed to have a clear boundary, dividing the space into two.

Soya's little body had been sucked into the singularity, and the surrounding space and her body showed signs of distortion. Her expression was extremely ferocious, as if she was suffering from inhuman pain. The blood spurted out from her mouth dyed the inside of the transparent mask red...

“Hurry…Run…”

Although the gravitational field around the singularity could not even escape the sound, Ashes still understood what she was roaring through Soya's mouth...
