"Could it be that Senior Sister Shiting's death was caused by another reason?" Zhang Chen looked at Xiang Yun and didn't know how to answer, so he gave the other party a step down.

"Hmm...... Actually, I also thought about whether there was another reason for that." Xiang Yun immediately added.

"Is it possible that Senior Sister Shiting was killed by a student or teacher in a chemical engineering institute, or was forced to jump off the building. So after death, the resentment will not be gone, wandering in the chemical building to find the murderer who killed him that day to take revenge?" Zhang Chen analyzed very calmly, and Wang Yizhi on the side looked at Zhang Chen's calm and calm appearance and felt very intimate.

"I don't know if Senior Sister Xiang Yun has seen Senior Sister Shiting's body? Maybe some clues can be found on the body, I think that if as Xiang Yun said, Senior Sister Shiting is beautiful and generous, and she has only learned people, and the possibility of suicide due to emotional disputes is very small."

Zhang Chen's words were sonorous and firm, which made Xiang Yun a little puzzled in his heart, is Zhang Chen a college student who has not yet been enrolled?

"The junior's head is really useful, but when the senior sister knew about it, senior sister Shiting had been dead for a long time. And the body has already been cremated, so I haven't been able to get any clues." Xiang Yun spread his hands and said, "Senior brother, do you have any other ideas, let's hear it, maybe it is the same as my senior sister?"

"Forehead......" Zhang Chen was speechless for a while, and Xiang Yun simply put the burden of re-analyzing things on himself, "Actually, the four of us were the main members of the school's supernatural club when we were in high school, and we have a lot of experience in studying these supernatural phenomena."

"Huh? Are there clubs in high school too? He is worthy of being a junior. It's amazing." Xiang Yun heard Zhang Chen say this, and the previous things were explained.

"As far as I know. If the ghost has been hovering in one place for a long time, then her physical body must have been placed here. In other words, Senior Sister Shiting's body must still be in this chemical building and has not been cremated, but as for the exact location, I don't know."

"Indeed, Master once told me about it."

"Senior Sister Xiang Yun, you have been observing Senior Sister Shiting's wandering spirit for a long time, right? I don't know what the specific route of the night tour is? Will you stop somewhere?"

"Well, yes. Sister Shiting's ghost first appeared in Room 714 of Block A, which was the real yàn room where Sister Shiting once was. Immediately after that, it will lead from the three connecting passages of Block A, B and C to Block B and then to Block C without any stops in between. until they reach the rooftop and disappear."

"Didn't you stop in between? Is there anything worth noting on the seventh floor of Block A other than 714?"

"Because I don't dare to startle the snake. So I didn't approach Block A every time, but just observed each other's movements in Block B and Block C."

"The ten problems are on the seventh floor of Block A and the rooftop of Block C, Senior Sister Xiang Yun, now we are taking advantage of the fact that the spirit has not yet appeared. How about investigating the relevant clues first?" Zhang Chen asked very seriously.

"No. In case the grass startles the snake, tonight's preparations will all be in vain." Xiang Yun immediately raised objections.

"In my opinion. Senior Sister Shiting was killed by someone in the chemical building, but the body was hidden in the chemical building. However, the death information from the outside world was only pronounced dead by the court because of the disappearance of Senior Sister Shiting for more than four years. As for whether there was a jumping off the building. It's hard to say."

"There is one thing, ask Senior Sister Xiang Yun. What are you preparing for tonight?"

"Naturally, I will subdue Senior Sister Shiting's wandering spirit, lest Senior Sister she can't think about it one day and start killing innocents indiscriminately."

"In the past few years, has Senior Sister Shiting been harmful?"

"No, but it is not ruled out that Senior Sister Shiting will not harm anyone in the future."

"If Senior Sister Shiting is really as I deduced, she is a good girl who is diligent and studious and wants to achieve scientific research results to repay the country, her alma mater, and her parents. And yet being killed by a mad murderer, and even suffering before being killed, and finally reduced to a lonely ghost, do you still have to subdue her and let the real murderer get away with it?"

"You have a point...... But Master said that ghosts and monsters do not belong to this world, and it is our duty to get rid of them."

"Rules are dead, but people are alive. You said with sincerity, what should you do now is it better to subdue Senior Sister Shiting or catch the real murderer?"

"This ......" Xiang Yun scratched her head, "It must be to catch the murderer...... But ......"

"It's nothing but not, catch the murderer and bring him to justice, Senior Sister Shiting's ghost will definitely leave on its own."

This Xiang Yun originally had an extremely firm position, and at the same time, he had been preparing for a long time to subdue the female ghost tonight, but at this time, his heart was shaken by Zhang Chen.

"If things are really as Brother Zhang Chen said, this senior sister Shiting is actually quite pitiful." Worm Ying muttered on the side, and Wang Yizhi also held Zhang Chen's arm and nodded vigorously.

"Without further ado, while it's not yet 11 o'clock, let's go to the top floor and see if there are any clues."

Before, it was led by Xiang Yun, but now it has become Zhang Chen. Xiang Yun, who was following behind, always felt that this junior was a little unusual, but no matter how it looked, he was an ordinary person.

When Zhang Chen opened the door of the real yàn room and walked into the corridor of Block C, he obviously felt that the temperature in the corridor had dropped by nearly 5C compared to before.

"The situation is a little wrong tonight...... "Before Xiang Yun finished speaking, Zhang Chen and his party were already about to walk to the corridor. [,！ Mouthful. He looked back at the dark and silent passage behind him, couldn't help but have filial piety in his heart, and hurriedly followed.

"The soul of this senior sister Shiting is still not moving in Block A, but according to the situation tonight. If a living person appears in the chemical building, they may become the target of their attack, and the low-level ghosts rely on the resentment in their bodies to drive their actions, no matter how kind they are in life, they are afraid that they will do something murderous at this time."

Zhang Chen thought about it and led everyone to the rooftop and began to search for clues. However, the time is approaching eleven o'clock.

"It seems that Senior Sister Shiting may indeed have fallen to her death." Zhang Chen stood on the edge of the rooftop, although it had been washed by wind and rain for several years, a gap the size of an ordinary person's foot was clearly visible in front of Zhang Chen's eyes.

"Senior Sister Xiang Yun, who are the people in the key chemical building on this rooftop? Do these people have anything to do with Senior Sister Shiting?"

"The keys are kept by the doorman, but many teachers are able to borrow the key from the doorman. I had a phone call with the seniors of Sister Shiting's class, and they said that Sister Shiting usually had little contact with people in school, and was focused on scientific research, and she had to go back to the dormitory very late every night."

"Could it be ......" said this, Xiang Yun's somewhat dumb head also figured it out, "I know, the senior also mentioned that Senior Sister Shiting's mentor often has contact with Senior Sister on weekdays. And the teacher's office is also on the seventh floor of Block A, not far from Shiting's real yàn room. I haven't seen that teacher since I enrolled."

As soon as Xiang Yun finished speaking, Zhang Chen suddenly had a tremor in the main soul stone, and pictures appeared in his mind, and Zhang Chen couldn't help but kneel on one knee.

One by one, the zombie faces with blue faces and fangs appeared in Zhang Chen's mind.

"Master, what's the matter?" Xiao Ni was not interested in the school's ghost catching at all, the whole process was just following Zhang Chen and protecting Wang Yizhi, and now he felt that his master's body was abnormal, and immediately spread the word.

"It's okay, tomorrow we will fly directly from Changsha to Tianfu, I'm afraid something big will happen here in Changsha."

After Zhang Chen got up, he looked to the west. I don't know why, I can actually feel the yin qi hundreds of kilometers away from me, and it is the zombie yin qi that I have clearly touched in my dream.

"It's already eleven o'clock, and I'm afraid that Senior Sister Shiting's ghost has already appeared in Block A. We have to hurry back to the stronghold now, and then go to Block A to check the clues after the senior sister disappears, if you meet the senior sister's geist, it will be troublesome to be regarded as an enemy by the senior sister."

Zhang Chen also nodded, the other party was already a low-level ghost and did not rule out the possibility of launching an attack on the living.

However, when the five of them walked down from the rooftop, Zhang Chen's brows furrowed slightly, because when he used his telekinesis to sense room 714 of Block A again, Senior Sister Shiting, who was still there before, disappeared. However, when he covered the entire chemical building with his mental power, he still couldn't detect the existence of any ghosts.

"Little Nirvana, things have changed. Protect Yizhi and this Senior Sister Xiang Yun, annoying things may come to the door."

Xiao Ni and Worm Firefly both changed their faces after hearing this, and began to concentrate on perceiving the situation around them. At the same time, the temperature in the corridor has dropped by nearly 10C compared to before, Wang Yizhi can only stick to Zhang Chen to keep warm, and Xiang Yun is hard to support her body.

Everyone followed the same path and returned to the previous analysis room.

"No, it's strange that the temperature hasn't dropped in the past few months." Xiang Yun muttered, and said to everyone, "I sprinkled a special powder outside, as long as the spirit passes by me, I can sense it, according to the previous situation, Sister Shiting's spirit will immediately arrive on the rooftop and disappear after passing here, and it will not appear again for the rest of the time."

However, time passed minute by minute, and there was no reaction outside.

"How so? In the past, at 11:15, the spirits would pass through here. Why hasn't it been 11:20 now?" Xiang Yun began to panic because of the change in what she expected.

However, Zhang Chen was invisibly monitoring the entire chemical building, and the ghosts sent by the strange network were getting more and more powerful every time, and he definitely didn't dare to take it lightly.

"Toot!"

In the silent and dark room, there was only the sound of five people breathing. However, the computer connected to the analytical instrument on the side suddenly rang and turned on automatically. In Zhang Chen's opinion, a trace of ghost energy began to escape from the main computer case.

However, the moment the computer is turned on, the mouse opens the browser without human control, and enters "13.live." in the address bar.
