I can rewind time to prevent death

Jialan had lost all desire to sleep, sat up, and prepared to pour herself a cup of hot water.

But just at that moment, she faintly heard Wan Cong's voice calling out from the upstairs bedroom, which was closed.

"Mom."

At first, Jialan thought she might have heard wrong since the voice was so faint. Perhaps she was still groggy from just waking up and had experienced an auditory hallucination.

She walked over to the water purifier and poured herself a cup of warm water which had been kept at a steady 50 degrees. Just as she was about to bring the cup to her lips, a blurry voice once again reached her ears.

"Mom."

This time, Jialan heard it clearly: someone was calling her.

She looked up and turned to face the tightly shut bedroom door on the second floor, sensing that the sound was coming from her son's room.

"Can't find his clothes again?" she muttered to herself as she took a sip of water, put the glass back down, and headed upstairs.

Standing in front of her son's bedroom door, Jialan hesitated for a moment before knocking and asking, "Congcong, was that you calling me just now?"

She waited a bit, but no one answered.

Jialan knocked again and repeated her previous question.

Still, there was no reply from inside.

After a moment of thought, Jialan gently turned the doorknob; it wasn't locked from the inside, so she opened the bedroom door directly.

She stood in the doorway, peering inside. The curtains were drawn open, and there was plenty of light in the room, but at first glance, she did not see Wan Cong.

"Not in the bedroom?"

Jialan talked to herself, thinking she must have heard wrong after all.

Just as she was about to close the door and leave, a familiar voice suddenly came from the bathroom of her son's bedroom.

"Mom."

Jialan was startled, turned back, and looked at the closed bathroom door in astonishment.

"Son, are you in there?"

She asked the question, but no sound came from the bathroom as if there were no one inside.

Jialan suddenly felt a chill run down her spine, an inexplicable sense of horror rising from her feet and spreading through her body, causing her to suddenly tingle all over with cold hands and feet.

She stood at the bedroom's entrance, gripping the doorknob, too scared to go any further.

After a brief moment with no further reply, Jialan prepared to close the door and leave.

Just then, the sound of someone talking came again from the bathroom, clearly reaching her ears.

"Mom, I'm in here."

Confirmed, it was indeed her son in the bathroom, and his voice sounded perfectly normal.

Jialan came to her senses as the initial sense of dread began to fade. She gently patted her chest, took a deep breath, and approached the bathroom door.

"Son, did you run out of toilet paper?" asked Jialan.

"No."

"Are you taking a bath? Do you need a dry towel?" Jialan asked again.

"No."

"Then what are you calling me for?" Jialan was perplexed.

"Mom, come in."

"You... Is it convenient?" Jialan inquired.

There was no response from the bathroom.

Jialan knocked on the door and said, "If you're taking a shower, it's not convenient for me to come in. Whatever you need, I'll leave it outside the door, and you can get it later."

"Mom, come in." The same words came through again, spoken with a calm tone that revealed no signs of abnormality.

"This child..."

Jialan was somewhat speechless, paused for a moment, pressed down on the bathroom door handle, unlocked it, and was about to push the door open when Wan Shouguang's voice suddenly came from behind her.

"Jialan, what are you doing in Congcong's bedroom? Where's the boy?"

Jialan stopped what she was doing, maintaining her position, and turned her head to reply, "He was calling me from the bathroom. I don't know what he's doing."

"Congcong, are you okay?" Wan Shouguang entered the bedroom and stood beside Jialan.

"Nothing, found the dry towel." Wan Cong's voice came from the bathroom.

"Okay, good."

Jialan casually closed the door, and the old couple left Wan Cong's bedroom one after the other, gently closing the door behind them.

In the bathroom, near the door.

Wan Cong stood there fully clothed, his mouth agape to an extent that no normal person could manage; still, the corners of his mouth did not tear. His eyes bulged slightly, his pupils turning a deep gray. In this state, he had been facing the bathroom door all along.

Even when his voice had sounded, he had maintained this bizarre pose with his mouth wide open.

As soon as the couple outside left, Wan Cong's gaping mouth slowly closed, and his face returned to normal, giving away no hint of strangeness.

Back in the master bedroom, Wan Shouguang said to Jialan, "Don't be alone with our son for the next few days. I still need to observe him. His condition is very unstable."

Jialan looked surprised; in fact, she had sensed it too, but as soon as she saw her son's familiar form and heard his familiar voice, her heart was void of any barrier, leaving only affection, regret, and an endless desire to make amends...

As they spoke, Wan Shouguang took out the Strangeness Interferer from the wardrobe, handed one to Jialan, and placed another in his pocket. He also pulled out a black object resembling a cigarette case and slipped it into his pocket as well.

This black "cigarette case," named Magnetic Knife Shrapnel, was produced in very limited quantities due to the demanding craftsmanship required. It was intended for those unfamiliar with the art of wielding a magnetic knife.

With the press of a button, the ejection port would instantly fire a blade formed by magnetic force; this blade could emulate the function of a magnetic knife, instantly slaying the targeted strangeness.

Of course, this required precision in targeting the strangeness; otherwise, it could not harm them, and it also had to hit the target at the peak of its power burst.
