Seeing that the woman was still in a daze, Rong Yu replied indifferently: "You aren't trying to investigate the truth? Then let's go to the scene and see if we can find anything. "

The current Fu Nuan did not know how to react, and could only stare blankly at the man in front of her. She thought that he was unwilling to get involved in this matter. But just when she was at her worst, he descended from the sky to help her solve her problem.

"Don't want to go?" The man let out a breath so close to him that it was almost as if he was teasing Ye Zichen with a smile, "Then forget it."

Fu Nuan finally regained his senses, and said repeatedly: "No, I want to go! However … Didn't the place get sealed off already? "

"I can take you in."

Fu Nuan naturally firmly believed in Rong Yu's words. If he said he could do it, then he definitely could.

"Thank you, Rong Yu."

The corner of Fu Nuan's eyes curled up, and finally revealed a trace of a smile. This time, she didn't pretend to be distant from him and call him director.

The man smiled faintly. His frown gradually relaxed. He didn't know when, but his emotions had always been moved by this woman.

Seeing her desperately trying to find out the truth, how could he just let her go and stay out of the matter?

When night fell, the troops on duty had already retreated, leaving only a few patrolling security guards behind.

Rong Yu brought Fu Nuan and took the chance when the security guards were patrolling elsewhere to enter the building through a side door.

The entire building had been suspended from being used. Not only had the explosion affected the laboratory, but even the ground floor had been severely damaged. It was clear how powerful the explosion was.

There was still the smell of burnt flesh around, Fu Nuan frowned, and lightly covered his nose.

Seeing that, Rong Yu said: "Wait for me outside."

Fu Nuan shook his head and looked at him stubbornly: "I want to go with you!"

She insisted on investigating this matter.

Rong Yu knew her personality, so he said lightly: "Follow me closely."

Fu Nuan nodded, he was about to follow along, but he extended his hand out towards her, following that was Rong Yu's low voice, which sounded extremely clear in the silent night.

"Grab my hand and follow."

Fu Nuan was stunned for two seconds. He did not think much about it at this time, and reached out to grab his hand, feeling the warmth of his palm. In that instant, he felt a palpitation in his heart, as if electricity had passed through his body.

She did not see the smile on the man's lips, nor did he notice her flushed cheeks.

In order to not attract attention, the two of them did not turn on their flashlights. They could only use the faint light and moonlight coming from the outside as they groped their way up.

The stairs were considered to be intact, so Fu Nuan did not know how long he followed them.

Rong Yu who was in front stopped and said softly, "We're here."

The stench around the experiment lab was the strongest, Fu Nuan endured the discomfort and followed behind him, entering the scene.

Rong Yu turned on the light on his phone, scanned his surroundings, then turned to look at her, shaking his head.

"Still not enough …" Fu Nuan was a little disappointed.

Before coming here, he thought he could find some clues, but after the explosion, the laboratory had been razed to the ground, and the magnesium powder stored inside had also disappeared.

"Go to the duty room and take a look. There might be clues."

Rong Yu held her hand tightly.

Nothing was known until the very last moment.

The two of them groped their way through the darkness to the duty room downstairs. Because they were a few floors away from the explosion lab, they were in a diagonal position, so they were the least affected.

A trace of hope once again ignited in Fu Nuan's heart.

Gently pushing the door of the duty room, the door swung open.

There were two registration forms on the desk in the on-call room. All the chemical laboratory users and the time were registered, one for the student and one for the teacher.

The two of them flipped open a book and browsed through it.

After a while, Fu Nuan realized that something was amiss. Lu Yanran's mother said that her daughter had called back one night and had been crying. And according to this record, Lu Yanran had come to the laboratory that night and stayed until very late.

He entered the laboratory at around 7 PM. It was already past midnight.

Had something happened to her in the lab over the past few hours? Fu Nuan carefully checked again, and discovered that other than Lu Yanran, no other students had come to the experiment lab that night.

She cast her gaze at Rong Yu, who was beside her, just in time to see him look at her.

"I have a discovery …"

The two of them spoke up at the same time.

"You first." Rong Yu looked at her with a heavy expression.

"Lu Yanran came to the laboratory at night on the 16th, and only left in the early hours of the morning."

With that said, Rong Yu's face became even heavier.

"In my teacher's registration book, there was also the 16th night. A professor came to the laboratory and left at dawn."

"Could it be …"

Rong Yu nodded his head, confirming Fu Nuan's guess.

The name of the professor in the registration book was Chen Zhenfeng, who was also the instructor of the three accident students.

A male professor in his forties and a female student in her twenties. If that really was the case …

Fu Nuan did not dare to think deeper.

Rong Yu had obviously thought about that as well. He shook her hand and said in a low voice: "If you search again, there should be a record of how long and how many magnesium powder the laboratory will store."

Fu Nuan seemed to have just woken up from a dream, as she looked for him together with him.

It was not long before he found the record book, but the data displayed in it was normal.

It was because it was too normal that people couldn't help but suspect that someone had deliberately erased the record so that no one would be able to find the powder.

At this point of the investigation, the traces of human activity were too obvious, and the biggest suspect in all of this was Professor Chen Zhenfeng.

"This matter definitely has something to do with their mentor." Fu Nuan clenched his fists in anger. If that was really the case, then that person was truly sinister!

"Who's there!"

Just then, a stern voice came from not too far away, scaring Fu Nuan so much that he shrunk his body. In the next second, he was already in Rong Yu's embrace, hiding in a dead corner of the duty room.

Two footsteps came over, the light from the flashlight was flickering, Fu Nuan was afraid of being discovered, he nervously held his breath, not even daring to breathe.

As for the man that stuck close to her, his forehead was already covered in sweat, his thin lips were pursed tightly, and his large hands wrapped around her waist, pulling her into his embrace.

Fu Nuan was practically sticking close to Rong Yu, and when she heard his drum-like heartbeat, she couldn't help but want to push him away, her ears turning red.

"Don't move." Rong Yu whispered into her ear in a low voice.

As the footsteps got closer and closer, Fu Nuan became more and more nervous, and his back was practically drenched in sweat.

However, just outside the duty room, the footsteps stopped, and a flashlight shone in.

Then she heard someone say, "Who's there? Did you hear wrongly? "

"I clearly heard a sound …"

"Stop talking!" "Someone just died in this building. It might have been those students …"

"Don't scare me!"

"Let's go!"

Hearing the voices of the two grow further away, Fu Nuan finally heaved a sigh of relief. Realizing that she was still trapped in Rong Yu's embrace, her face heated up as she stuttered, "I can … "Let go."

This time Rong Yu did not tease her and released his hand.

"Let's go." Rong Yu said in a deep voice: "There aren't any valuable clues here, we have to think of something else."

Fu Nuan nodded. Just as he walked to the door, he suddenly thought of something and turned around to follow the two registers on the table. Then, he quickly followed him and left.

Rong Yu pulled her along and ran all the way until they were far away from the experimental building.

She turned her head to take a look and ensure that no one discovered him. She was really lucky in her heart, and was just about to turn around and thank Rong Yu when she was caught off guard and pulled into his embrace the next second.

Without waiting for Fu Nuan to react, the man's lips had covered her lips. Suddenly, the intensity of the kiss made her unable to breathe.
