Erosion

Zhao Ying looked at the black scary circle in the middle of the room, and suddenly realized, did this circle get bigger?

Jiang Shan's fingers were no longer visible, and the circle was clearly encroaching on a larger area.

"It seems something is wrong..." Zhao Ying's voice trembled a little. "It wasn't like this before."

The power of this black shadow seemed to become even more terrifying. From the beginning, it seemed to "hug" Jiang Shan, to wrap it behind, and then it continued to expand.

Wei Yuan said, "Help me up."

Zhao Ying picked up the stick on the ground and handed it to him, and at the same time helped Wei Yuan up.

It can be seen that Wei Yuan's feet are attached to the ground. Although he needs to use branches for support, he looks like he can really stand with the help of external force.

Zhao Yingcai discovered that Wei Yuan was very tall, almost as tall as Gao Wenwu, but he was a little thinner because of sitting in a wheelchair for a long time.

"Ashan could hear us before, and seemed to be able to respond," Zhao Ying paused, and said in a trembling voice, "But now I can't see her at all..."

The diameter of this circle, or sphere, has now exploded to about two meters long, not only completely submerging Jiang Shan's figure, but also the wriggling black lines seem to swallow everyone who approaches.

Symbiotic strangulation.

This thought popped into Zhao Ying's mind.

"Why can you all see the black shadow here?" Wei Yuan's voice came from the side.

When Zhao Ying and the others narrated what happened just now, Wei Yuan could hear clearly that the shadow in the library was a shadow they couldn't see.

Wei Yuan's sentence is not actually a question, but a bit thought-provoking.

And this shadow, can it hide under people's feet?

Zhao Ying wanted to say something, but when it came to her lips, it still became: "Ashan said... because the shadow in the basement is an experimental product."

An experiment in the God equation.

Wei Yuan didn't say right or wrong, he leaned on a tree branch and took two steps forward. If there is a camera at this moment, it will be so subversive to record all this.

"Give me the candle." Wei Yuan said to Zhao Ying. "Stay where you are and don't come over."

The black circle was expanding, squeezing the already cramped basement space, and it was very dangerous to walk around in the room at this time.

Wei Yuan walked around alone, he wanted to see the "God's Equation" on the wall.

She watched Wei Yuan almost rubbing the edge of the "sphere" to the side of the wall. He held up the candle and carefully looked at the symbols and words on it.

Zhao Ying was worried, she really hoped that Wei Yuan could see something.

"UV." Wei Yuan said quietly.

What? "What does that mean?" Zhao Ying was curious.

Wei Yuan looked thoughtful: "The abbreviation of Ultraviolet."

Ultraviolet acronym?Zhao Ying was slightly startled. When the three of them were observing just now, everyone saw those letters but no one noticed it. In other words, it was difficult for them to realize the two characters of uv in the ghostly symbols full of messy letters on the wall. Can there be any single particularity.

But Wei Yuan noticed these two letters because of his previous "little experiment" outside.

It was Wei Yuan who took out that tiny flashlight from his breast pocket.UV flashlight.

Wei Yuan turned on the flashlight and saw a seemingly transparent white beam. Wei Yuan turned around and glanced at Zhao Ying first: "You'd better stand a little further away."

There is no coincidence, all seemingly coincidences may be clues.

Zhao Ying took a step back subconsciously. She didn't understand what Wei Yuan was going to do, but Wei Yuan raised the ultraviolet flashlight in his hand, and the white light shone on the black sphere.

For a moment, Zhao Ying seemed to see the sphere tremble violently.

There seemed to be a scream coming from that sphere.

Zhao Ying stood on the edge of the big pit, and was about to fall one step further back. She looked at the "sphere" that suddenly mutated without moving.

A sense of horror swept over. The black linear substances tightly wrapped around the outside of the sphere began to lose their regularity and structure. Under the white light, they suddenly sank crazily and began to mutate.

Wei Yuan enlarged the radiation area of ​​the light, he was as calm as a statue.

The white light source covered the "body" of half of the sphere, and more and more sharp howls of pain came from the sphere itself, while those black silk threads were completely scattered, and the bumps shrank, as if they were about to disintegrate and explode.

Until Wei Yuan slowly said: "This thing is afraid of ultraviolet light."

Zhao Ying couldn't believe what she saw, especially in the flashlight, she suddenly remembered what she saw on the library expansion map and felt puzzled, that is, when the library was expanding, One substance that has been used a lot -- titanium dioxide.

At this time, she remembered one of the most remarkable properties of titanium dioxide, "anti-ultraviolet..." Zhao Ying's face changed slightly, titanium dioxide, a substance with strong anti-ultraviolet rays.All those substances are designed to block ultraviolet rays.

The black substance on the outside of the sphere seemed to be dying, and suddenly there was a black line, like a tentacle, attacking Wei Yuan in an instant!
"Dr. Wei!" Zhao Ying suddenly turned pale.

And Wei Yuan has been standing against the wall, the black tentacles pierced towards his face, he turned sideways instantly, the tentacles flew into the air, and even shrank as if they were burned the moment they touched the wall return.

Both Wei Yuan and Zhao Ying saw this scene, and a light flashed in their hearts almost at the same time.

The wall, this wall full of equations is also afraid of the shadows?

The God Equation, the Corroding Shadow, the Trembling Library, the End of Eternity.

Chaotic yet orderly everything.

The tentacles still did not give up on attacking Wei Yuan, but since Wei Yuan saw the way, he immediately stuck to the wall to remain unchanged and respond to all changes. At the same time, the ultraviolet white light in his hand hit the "body" of the sphere without slackening for a moment.

The disintegration speed of the sphere seemed to be faster, and at the same time, its variants became more frenzied. When those blacks shrank wildly, it seemed that a "human figure" gradually emerged.

That huge "face" and distorted facial features belonged to that "mother".

(It) she seems to be wailing, but also seems to be accusing.

Zhao Ying felt that she would have a psychological shadow all her life.

Is there any tragedy more pure than this? Tragedy reveals horror to every pore.

The huge face was tightly pressed half a foot in front of Wei Yuan, as if it wanted to swallow this man, just like the person it wanted to swallow.

Wei Yuan also looked at the huge "face", the "eyes" with two black holes on the face that were constantly sunken, and black dust was falling from the eye sockets... as if they were crying.

The white light shone on that face, and finally that face disappeared bit by bit, fell off, and turned into ashes.

A family of three, a crazy father, a sacrificed daughter and wife (mother), this is similar to the information Wei Yuan received, but the sequence seems to be a little different.

When that face finally dissipated, the white light shone on it, as if it had become that face emitting soft light.With tenderness, compassion, like a mother.

Wei Yuan didn't know if it was pity in his eyes.
