The Death Knell

The thing that the sole of the foot stepped on was very small, about the same as the nail of the little finger, and it felt a little sharp. It seemed to be stuck to the ground, so that when Deathstroke kicked it just now, it felt a bit stinging.

I bent down and touched it with my hands. Humans still rely more on the feeling of their upper limbs. Although their feet can be used, they are more accustomed to using their hands to determine the shape of an object.

It's like waking up in a dark room, and people are looking around for the door to leave. At this time, even if their legs are longer than their arms, most people stretch out their hands and slowly explore around instead of using their feet.

"It feels very hard. Well, it's still a little tough and solid. Its shape has three wedge-shaped faces, but when you touch it from another angle, it seems to have a triangular mouth."

Deathstroke, smiling because of his good luck, groped for an invisible object on the ground and described its shape to himself.

"Hey."

There is no need for verbal description at all. The strangulation, which can also share the feeling, screamed. It reminded that this structure has a corresponding name in the host's memory. It is called the Penrose Triangle.

This thing is essentially faces on different planes. When viewed from a certain angle, it will form a triangle on a two-dimensional plane. It will make people think it is a three-dimensional object, but it cannot exist in the three-dimensional world at all. It is a projection of four-dimensional space. ’

This long list of descriptions is very abstract, and is similar to things related to mathematical geometry, but the concept of space is closely related to these things.

But it can be explained in a simple sentence - Penrose triangle is something that does not exist in reality.

"Yes, it's a Penrose triangle. And it seems to be stuck to the ground, so strong." Su Ming stretched out his hand and tried to break it, but he was worried that it would be crushed, so he just pulled it out with a little shaking. "Speaking of which, How come I have any knowledge of spatial geometry in my head?”

"Hey." Douya's two thin tentacles trembled, just like human hands.

It can't remember clearly. After all, it has eaten many enemies in the past. Who knows where this knowledge came from, but this is not the point. The point is, is it some kind of substance that makes up this triangle?

"This thing is probably what we are looking for, strangulation."

Su Ming, who was holding a cigarette, used his hands together, shaking the thing in his hand like pulling out a carrot. Although he couldn't see it, he could feel that it was a little loose and was being pulled out of the ground. However, the ground under his feet still looked intact. Not a single hole:

"This thing is in a special superposition state, but I can touch it. It is most likely a substance, but..."

"Hey."

The symbiote has finished saying what the host wanted to say, but it is most likely not made of atoms and molecules.

Therefore, human common sense cannot be used on it, nor can the symbiote's phagocytosis analysis methods be used.

The definition of object or substance is not as simple as people think in daily life. Strictly speaking, it can be summarized as - object is the spatial distribution of mass, and its basic attributes are mass and space.

But it also has extensional attributes. All objects are actually divided into 'spiritual objects' and 'real objects', which refer to the distribution state of a certain finite mass in a certain limited space.

This invisible but tangible thing is probably a three-dimensional manifestation of the former.

"It doesn't matter, it's just a small problem. I'll take this thing and study it with God and Lucifer later. Maybe they know?"

Su Ming, who straightened up, was more optimistic. He had already pulled out the 'unknown strange object' from the ground. From a tactile perspective, this thing had a triangular shape no matter how it was touched, but it was clearly not a triangle:

"It's a pity that the Fortune Elixir can only affect my luck in small things, allowing me to achieve ideal results; in big things, it can't affect the direction of the world, nor can it affect the collective destiny of mankind."

Although the Fortune Elixir was good, it was useless to be greedy. Otherwise, Su would drink a few pots of wine tomorrow morning and see if his luck could bring out the weakness of CAAT directly in front of him.

But I can only think about it.

The little black bean sprout shook its head, and its crescent-shaped eyes narrowed: "Hey."

What it means is: This is normal. Fortune Elixir is just a magic potion, it is not some fairy water.

If you really want to think of miraculous effects, the raw materials should not be some herbs and eggshells and tentacles of magical animals. At least you have to grab some gods and stuff them into the crucible. There may be hope in boiling out their essence.

The old half-blood prince Snape might not be able to keep up with the skill of brewing this kind of potion. Instead, it would be enough to trade it with Nurgle, who was best at brewing potion.

"Okay, let's try the characteristics of this thing."

Su Ming waved his arms, like a little boy waving a big sword in his imagination.

But this is not even an air sword, because it is clearly held in the hand and feels real when swung, but it did not cause any noise, at least it did not interfere with the air.

"Well, I'm sure, it can't be used to kill people, at least it can't be used to kill people who exist in the three-dimensional world."

"Hey."

The strangulation also confirmed another thing, that is, this invisible thing cannot be eaten, and the existing entity cannot be destroyed, which seems to be another characteristic of it.

"Okay, I'm not a researcher. If the things I get can't be used directly to kill enemies, then I have no research direction." Deathstroke looked at the empty room. There were still some traces of the previous owner living here: "Strangler, do you think we should continue searching to see if there is anything else, or should we go straight back to find God Girl?"

"Hey." Strangler has no objection. It is a symbiote, and it always goes wherever its host goes.

Besides, didn’t the host already have a plan before talking to himself?

Yes, there is indeed a plan. According to speculation, the mysterious item in hand should be the collision of the concepts of CAAT and Lucifer, thus forming a certain derivative.

And they are all beings with multiple concepts, so it stands to reason that there will be other types of collision traces, or if you are more lucky, you may be able to find direct clues to CAAT.

Let’s search the town first.

"Okay, then you know what to look for. I'll take a rest." The man walked to the dining table of this house, pulled out a chair and sat down. The kitchen of this house was not as clean as Christopher's house. But it has a more lifelike feel: "Go ahead and touch every inch of land in this half of the town. If necessary, dig three feet into the ground."

"Huh?" Strangler asked him cutely, was it feet or meters?

"Asking knowingly, you know what I think, and this is an idiom. How can the ancestors of the Celestial Dynasty use feet?" The Supreme Mage was amused by the symbiote's joke of pretending to be stupid. He flicked the bean sprouts on his shoulders with his fingers and looked at it. It swayed back and forth like a bobblehead: "Just do it, I'm not miserable enough that I need to amuse myself."
