He has been reincarnated through countless worlds, adorned with billions of mythological terms!

After Yun Yi finished reading it, he folded the note, and his palm caught fire, instantly burning to ashes.

After reading all this, he roughly understood what was going on.

Simply put, my mother is sick, very seriously ill, and it's not any kind of disease that exists in this world; there is no cure.

These biological studies began when he was conceived.

There should be some progress, but it's not certain yet.

They later developed a solution, but were unsure if it could save their mother.

Perhaps the mother's illness became too severe in the end, and she used it, but in doing so, she became the mother's body.

At that time, Yun Nian's mother was already pregnant with her, which caused Yun Nian to also suffer from the infection.

At that time, however, Yun Nian was not affected at all.

At that time, my father wanted to take Yun Nian for research, but my mother stopped him.

Later, the father probably realized that there was no way to save the mother, so he finally chose to release the virus, let it evolve on its own, and let the mother, as the mother body, find a way to save herself—after all, the mother was fully involved in that experiment, and she was also the best biologist in the world.

After thinking all this through, Yun Yi had a general idea of ​​what was going on.

In fact, when he discovered that Yun Nian could perfectly contain the virus without any problems, he had some suspicions.

He was not completely convinced until that person said, "Your sister is the chosen one."

To be honest, his family's story is quite dramatic.

Without his intervention, the normal course of events would have been—they entered the shelter, and then the sister, for some reason, came out and, through a series of coincidences, entered this place, saw the information above, and used the virus.

That's right, the golden one is the real virus.

He probably knew what his father was thinking: his sister was just an accident, and his mother was his true love.

If my sister successfully uses the virus, we can use that to develop a real antidote and save our mother.

If nothing unexpected happens, given her current status as the chosen one, she's almost certain to succeed.

The only uncertainty now is why his father brought him here.

You should know that it's very difficult to get in here under normal circumstances.

Going out is even more impossible, because all the zombies have gathered here.

The father had no idea that he could clean up all the zombies.

Just as he was thinking this—

The ceiling is shaking.

The vibration wasn't from the laboratory, it was from the ground.

Yun Yi did not move.

He stood in front of the control panel, still clutching the ashes of the piece of paper in his hand.

Ashes drifted through his fingers, landing on the metal box and beside the two syringes.

"Xiao Yi".

Yun Tianheng's voice came from above—not from the radio, but from somewhere on the ceiling, from a hidden speaker that glowed faintly red in the shadows of the dome.

"What you are hearing now was recorded before I injected the Primal Elixir."

"If you're hearing this, it means I made the right bet—you made it this far alive."

Yun Yi looked up at the speaker.

Yun Nian lay on his back and looked up, but she couldn't see anything.

"There is an emergency communication device under the laboratory, which uses a frequency reserved for military use."

"Open it, someone will answer."

"That man is my friend, and he will send someone to arrive within three days."

"There is enough food and water in the lab to last you a month."

The recording stopped.

The hissing sound of electricity lingered in the empty hall for a long time.

Yun Yi glanced down at the metal box on the control panel.

Two syringes lay side by side, one gold and one transparent.

He picked up the golden one and looked at it under the light—the liquid was flowing in the glass tube, like liquid amber, with countless tiny specks of light suspended inside.

"Nian Nian".

"Um."

"Dad left something upstairs."

"We have enough food and drink to last us a month."

"Someone else will come to pick us up, armed with guns, to protect us."

Yun Nian peeked out from his back, glanced up, and then shrank back down.

"And what about Dad?"

"have no idea."

Yun Nian remained silent for a while.

"Is that golden one for me?"

Yun Yi paused for a moment.

How did you know?

"I just know."

Yun Nian's voice was very soft, "Dad said it was for me."

"He said that was the real cure for me."

Yun Yi looked at the syringe in his hand.

The golden liquid spun slowly under the light, and the specks of light inside looked like fireflies or stars.

He recalled what Wen Ruotang had said in the shelter: "Viruses evolve, and so do people."

She wasn't talking about Yun Yi, she was talking about Yun Nian.

"Niannian, do you know what will happen after this injection?"

"Know."

Yun Nian slid off his back, stood on the ground, and looked up at him, saying, "It will turn into something like Mom."

Her voice was very steady, so steady that it didn't sound like that of an eight-year-old child.

Yunyi squatted down to look her in the eye.

"Aren't you afraid?"

"Afraid."

Yun Nian hugged the ugly rabbit a little tighter.

"But I don't want to be protected by my brother anymore."

"I also want to be someone who protects my brother."

Yun Yi remained silent for a long time.

He handed the syringe to Yun Nian.

"If it hurts, cry it out, don't hold it in."

He had actually considered giving the real antidote to Yun Nian.

But he wasn't sure if it was really the antidote—the reason he could tell that the golden potion was the real virus was simply because he sensed that the virus it contained was roughly the same as the one in his mother's body.

He couldn't be sure whether the transparent vial was the real antidote.

Although he is no longer considered human, that doesn't mean he understands everything.

If we don't give her the antidote, given the condition of my sister's body—although the virus has fully adapted to her body, it doesn't mean it will never break out.

It's just uncertain when it will erupt.

Yun Nian took the syringe, looked at the needle, and then looked at her arm.

She tucked the ugly rabbit under her arm, rolled up her sleeves, and revealed her fair forearm.

When the needle pierced her skin, she bit her lip and didn't cry.

As the golden liquid was pushed in, she began to tremble—starting with her fingers, then her wrists, forearms, and shoulders; her whole body was shaking.

Golden lines appeared beneath her skin, the same as Yunyi's before, but denser, brighter, and deeper.

The lines started from the injection site and spread upwards along the blood vessels, across the elbow, upper arm, shoulder, neck, and cheek—

Finally, it all converges at the center of the forehead.

Yun Nian's skin was glowing.

It wasn't the kind of explosion where scales burst open; it was something else—a warm, dawn-like light seeping from the bones.

The golden lines, after covering the entire body, did not disappear but sank into the skin and merged with the blood vessels.

Her heartbeat changed.

Previously, it was more than eighty beats per minute, but now it has dropped to forty, thirty, twenty—each beat is as heavy as a drum, making the air tremble.

Yun Yi stood in front of her, watching her pupils change from black to gold, and then from gold to a color he had never seen before—not amber, not gold, but something between liquid and light.

The brightest spot was between her eyebrows, as if it had been branded with a hot iron, burning through her skin, skull, and brain, and connecting directly to some deeper place.

"Nian Nian".

She didn't answer.

His eyes were open, but he couldn't see anything—there was no reflection of him in his pupils, only a flowing gold.

Yun Yi didn't call her again.

He turned and glanced at the metal box on the control panel.

The other syringe was still inside, transparent, and the liquid inside was as still as stagnant water.

He picked up the syringe and put it in his pocket.

Then he picked up Yun Nian and placed her on the chair next to the control panel.

Her body was burning hot; you could feel it even through her clothes, like hugging a stone that had been baking in the sun all day.

She is still breathing.

Slowly, deeply, each exhale was accompanied by golden specks of light escaping from the corners of the mouth, like the white breath exhaled in winter.
