"Colorless and odorless fuel."

Langsheng's words were interrupted and he looked at Quan Yi. He kept his head down, his hand rubbing over something.

She understood, touching the railing, slippery and sticky.

"But there are so many people in this building, and it's impossible that no one will not touch the railing if they don't go upstairs." Langsheng frowned, this is indeed a flaw, but it is thought-provoking.

"So, what we want is to keep going."

……

A corner of the building was burned, but there was no danger of collapse.

The higher the layer, the higher the temperature. The heat has not yet dissipated, and the oxygen has dropped somewhat.

When he reached the first floor from the top floor, Quan Yi stopped.

"Looks like you can assume it." Quan Yi pursed his thin lips and looked around at the scorched floor, which was pitch black and smelled of electronics.

This layer is noticeably messier and darker than any other. This floor is where the explosion occurred, and it can be known that it was caused by the explosion of the computer and caused the fire. Then the murderer must have been prepared to pinch the time point and finish sprinkling the fuel.

However, all the computers were destroyed, and it is unknown which computer caused the explosion.

"So, it's done by people at the top."

Otherwise, it would not have exploded at such a high level. The best way to explain this is that there are so many pairs of eyes on all electrical appliances except for computers that can cause explosions.

Everyone knows that the top level is the office floor of the president of the company. Then the next level, it should be the manager's.

Quan Yi instructed the walkie-talkie in his hand: "Type out the list of managers of this company for me." ”

"How did he escape? There are also living people on this level, and if he detonates by standing at a distance and throwing something, then they should be able to see it. Langsheng walked through the aisles, looking left and right at the debris on the ground, and the desks were all turned into scrap boards.

Quan Yi glanced at it and asked, "Suspect that it was a mercenary?" ”

"No, the mercenaries don't use that method. It's just an ordinary frame-up that caused the fire, and it's impossible to have anything to do with the mercenaries. Langsheng refused, she knew very well that mercenaries would not need these means and fuel.

Since they were all half-ruins and fragments, and they couldn't find any new clues, the two went directly to the hospital to ask those people.

The scene could not be found, the only thing was to ask the surviving people.

"There was only one manager on that floor, and one deputy manager and director were spared." The subordinate handed a piece of paper to Quan Yi and reported the situation.

Three people. I just don't know if the murderer is among them.

The wards were divided according to the floors, and when Quan Yi and Langsheng entered, the two were still in a coma.

The other is a bruise on the arm, and the skin trauma is not a big deal.

"Miss Yang." Quan Yi glanced at her indifferently and put down the list in his hand.

The woman in the hospital bed was too bland and didn't seem to have experienced the explosion at all. Her face was very bad, and her mouth was pursed into a line, but she could feel her detachment.

Yang Xiu stared at them deadly, her hands clutching the sheets and bedding, and her face was even worse.

"Miss Yang, tell me what you know." Langsheng's tone also changed, because her clothes were too intact.

How intact? There was no trace at all, but it was still very dirty.

Yang Xiu said bluntly: "I don't know anything." I was not involved in the explosion. ”

"Miss Yang, evidence. It's not for you to prove yourself. Quan Yi approached step by step, and his unhurried tone made people's hearts beat faster.

Yang Xiu showed fear, her expression was as dead as silence, and her eyes were wide open. In the end, he muttered, "It wasn't my sister who did it, it must not be!" ”
