I can rewind time to prevent death

Seconds later, the black shadow discovered its anomaly. It looked left and right and quickly locked onto Zhang Chengjing who was stretching out his hand.

"Roar!"

A wave of extremely strong and invisible ripples spread out, violently hitting the walls of the quarantine room and making a buzzing sound.

Zhang Chengjing, standing in the middle of the room, had his clothes billowing and his hair blown back, but his body remained motionless.

The black shadow was still dissipating, but in the process, the drifting black mist no longer vanished. Instead, it started to congeal into a second, a third, and even a fourth black shadow.

However, as soon as they formed, these black shadows would disperse, unable to maintain a humanoid shape for long.

The black shadow in the center let out a hiss, shaking the glass walls on all sides. Strong sound waves formed an acoustic echo in the quarantine room, buzzing loudly.

Outside the glass room, the onlookers could only hear a long buzzing sound. Their eyes were wide open, staring at the activity inside. They saw Zhang Chengjing stretch out his other hand, slowly pressing down from above the black shadow's head.

Yan Junze knew that between Zhang Chengjing's palms, a powerful magnetic field must have formed.

The black shadow, not fully materialized and unable to exert its full strength, now couldn't resist. It began to wail, its form shrinking slowly, gradually retracting into the Turquoise.

After about less than a minute of stalemate, the black shadow completely disappeared. The Turquoise jumped again, showing no further abnormalities and seemingly returning to normal.

Zhang Chengjing, holding the Turquoise, walked to the quarantine room door where Shi Yanan immediately opened it.

After coming out, Zhang Chengjing first returned the Turquoise to Yan Junze, then said to Wan Shouguang, "Let's go, I'll accompany you to input the energy maximum and minimum values of this 'strangeness.'

The two went over to the computer.

Shi Yanan, pointing at the Turquoise in Yan Junze's hand, said, "This thing is really powerful. It can at least create a Grade B incident, can't it? How did you seal it inside?"

Yan Junze shrugged, "I found this Turquoise."

Shi Yanan: "..."

A moment later, Zhang Chengjing, who had entered the energy values, came over and asked Yan Junze, "Where are those black stones of yours?"

Yan Junze was taken aback, realizing that Zhang Chengjing wanted to test the energy output of the Black Spirit Pearls as well.

At that moment, Wan Shouguang approached and said, "Old Zhang, you don't need to test that yourself. You can put it into the energy tester over there, and it will automatically give you the energy range value."

With that, he looked at Yan Junze.

Yan Junze gave an embarrassed smile and asked, "Where is the restroom here?"

Shi Yanan pointed upstairs, "It's on the negative first floor."

"Why doesn't this floor have a restroom?" Yan Junze was curious.

Shi Yanan explained, "The magnetic field in the restroom is the most chaotic. Most of the laboratories here eliminate the impact brought by such chaos. Though we have technological means to isolate this impact to the greatest extent, under Professor Wan's directive, in order to make the experiments as perfect as possible, we decided not to include them."

"No wonder many strangenesses emerge from toilets!" Yan Junze muttered to himself.

"The chaos of thoughts and will is the root of magnetic field disturbance," Zhang Chengjing took over, "The toilet is one place, and the hospital is another. Usually, in larger public spaces, some secluded corner almost always harbors strangenesses. The difference is just the strength of the strangeness."

Yan Junze nodded.

Shi Yanan walked ahead, saying, "I'll take you there."

"It's so far away, I think I'll pass," Yan Junze shook his head.

Under the surprised gaze of everyone, he turned around, deliberately reached into his crotch, and slowly, very slowly, pulled out a jet-black stick about the length of half an arm.

This action was intentionally done for the others to see. In fact, he had taken the stick from the miniature of the Spacetime Atlas in his mind.

The only place on his body that seemed capable of hiding a stick half an arm in length was there, so Yan Junze had no choice but to pull the stick out in a "drawing" motion from that spot.

Turning around, he saw Zhang Chengjing and Wan Shouguang looking straight at him and the stick in his hand, eyes wide open, their eyeballs almost popping out. As for Shi Yanan, she had covered her eyes with both hands and stepped aside, not daring to lower them.

Holding the black stick in his hand, Yan Junze smiled awkwardly, thinking that if he had known Zhang Chengjing would come down now, he would have taken the stick out in advance.

Zhang Chengjing and Wan Shouguang looked at the stick, then glanced down at Yan Junze's right leg pant leg. Like Gu Bai who had seen Yan Junze do this in the photo studio, they appeared to be measuring the length of both items with their eyes.

Not allowing them to speculate further, Yan Junze handed the stick to Wan Shouguang.

Wan Shouguang hesitated for a moment, seemingly reluctant to take it directly.

For some reason, Yan Junze blurted out, "It's clean, don't worry."

Wan Shouguang, with two fingers, pinched the handle of the stick and said to Shi Yanan, who was covering her eyes, "Yan'an, put it into the tester."

Only then did Shi Yanan lower her hands. She had not considered this aspect and, glancing at Yan Junze, her gaze swept across his pant leg before grabbing the stick and heading to the energy tester, shoving the item inside.

The tester was activated, the lights came on, and the stick gently swayed inside. Soon after, the lights went off, the swaying stopped, and a line of text displaying the energy range values of the stick appeared on the screen at the top of the tester.
