Chapter 189

"Colorless and odorless fuel."

Langsheng's words were interrupted and looked at Quan Yi. He lowered his head and rubbed something with his hand.

She understood and touched the railing. It was slippery and sticky.

"But it's impossible that there are so many people in this building. No one will not touch the railing without going upstairs." Langsheng frowned. This is indeed a flaw, but it is thought-provoking.

"So what we want is to continue."

……

The building burned a corner, but there was no danger of collapse.

The higher the layer, the higher the temperature. The heat has not dissipated, and the oxygen has decreased.

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

"It seems that it can be assumed." Quan Yi sipped his thin lips and looked around the charred floor. It was dark and smelly.

This layer is obviously more chaotic and black than any other layer. This floor is where the explosion happened. You can know that it was because the computer exploded and then caused a fire. Then the killer must be ready to pinch the fuel at that time.

But all the computers were destroyed, and I don't know which computer caused the explosion.

"So, it was done by people at the top."

Otherwise, it wouldn't explode at such a high level. The best explanation is that there are so many eyes on other electrical appliances except computers that can cause explosions.

As everyone knows, the highest level is the office of the president of the company. Then the next level should be the manager's.

Quan Yi said to the walkie talkie in his hand, "type out the list of managers of this company for me."

"How did he escape? There are also people living on this floor. If he uses standing at a distance to throw things to detonate, they should be visible. " Langsheng walked through the aisles and looked around at the fragments on the ground. His desk had become a waste board.

Quan Yi glanced obliquely and asked, "is it suspected that the mercenary did it?"

"No, that's not what mercenaries do. This is just an ordinary frame up leading to a fire. It is impossible to have anything to do with mercenaries. " Langsheng refused. She knew very well that mercenaries would not need these means and fuel.

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

I can't find it at the scene. The only thing is to ask the surviving people.

"There is only one manager, deputy manager and director on that floor." The subordinates handed Quan Yi a piece of paper and reported the situation.

three people. I just don't know if the killer is among them.

The wards were divided according to the floor. When Quan Yi and Langsheng went in, they were still in a coma.

The other is to scratch the arm. Skin trauma is no big problem.

"Miss Yang." Quan Yi gave her a cold look and put down his list.

The woman in the hospital bed was so insipid that she didn't seem to have experienced the explosion at all. Her face was very bad, her mouth closed into a line, but she could feel her alienation.

Yang Xiu stared at them, 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 good is it? There's no trace, but it's still messy.

Yang Xiusheng said, "I don't know anything. I was not involved in the explosion. "

"Miss Yang, evidence. I can't prove myself. " Quan Yi approached step by step, and his relaxed tone made people's heart beat faster.

Yang Xiu showed her fear. Her expression was dead and silent, and her eyes were wide open. Finally, he murmured, "it wasn't my sister, it must not be!"
