It is very difficult to investigate a fire clearly.

After all, in this day and age, there were no cameras, and no one saw how the fire started.

In addition, the accountant Liu Xiaocui was not in the office at the time. How did he ignite the fire at regular intervals?

Team Liu went into the office and checked around, but found nothing.

After he came out, he looked at Li Donglai and said: "Director Li, this matter is more difficult to deal with! There is nothing abnormal in the house, and although there are traces of dirt inside, according to the financial officer Liu Xiaocui, there are frequent power outages here, so

A kerosene lamp was prepared in the office, and Finance Liu Xiaocui claimed that the kerosene lamp might have been broken during the fire and the kerosene inside flowed out, so the fire had nothing to do with him!"

Li Donglai asked: "What did the comrades from the fire brigade say?"

Captain Liu smiled bitterly and said: "The captain of the fire brigade is an old friend of mine. He is extremely concerned about this case and even brought the most important equipment in the fire brigade. But you also know that the equipment in the fire brigade is still very crude.

Yes, even the fire brigade has no way to confirm that the fire was really caused by kerosene."

Li Donglai frowned when he heard this. If this continues, these people might escape punishment!

Of course, in this day and age, the rules are not so strict.

If the Security Section wants to investigate something, it has many methods, but these people are very well-founded, especially Director Liu and Deputy Director Wang.

Not long after the two of them were arrested, Factory Director Yang received several phone calls begging for mercy. The people on the phone were all well-connected.

If Li Donglai hadn't insisted on his opinion, Factory Director Liu and Deputy Factory Director Wang might have been let go now.

So we have to find evidence of their arson as soon as possible!

"Old Liu, follow me and go into the office to check again. We can't let go of any clues! You also know that these guys are misbehaving in the field. If they don't get the punishment they deserve, there may be others in the future.

Keep learning!"

Captain Liu is a very ideologically aware person, and his face suddenly became serious when he heard this!

By this time, it was getting dark, and everything was dark. Team Liu called a few team members to put together seven or eight flashlights!

Although the power of the flashlight is relatively low, the brightness of seven or eight flashlights together is about the same as that of a lighting lamp, illuminating the office brightly.

The office was burnt black and there were debris everywhere.

All those account books were burned to ashes.

In later generations, there seems to be a technology that can restore burned ledgers to their original state, but it is impossible in this era.

Li Donglai asked Team Liu to adjust the lights and search for suspicious places bit by bit, but he couldn't find them after searching for a long time.

Captain Liu couldn't help but said with some dejection: "Director Li, let's just forget about this matter. These people's hands and feet are so clean that we won't find anything!"

"etc!"

At this moment, Li Donglai seemed to have discovered something. He pointed at a wire and said: "Liu Brigade, please bring someone to cut the wire now!"

"There doesn't seem to be anything wrong with that wire!"

Although Captain Liu didn't care, he still obeyed Li Donglai's order and stood on the chair, picked up the pliers, and carefully cut off the wires.

As soon as he took it in his hand, he felt something was wrong.

This wire is not a whole wire, but consists of two wires. One of the wires is different from the original color and is thicker.

"What is this?" Team Liu looked at the spring-like wire and frowned: "The wires are very tight now. Who would be willing to wind the wires like this!"

Li Donglai said coldly: "Team Liu, this is not a wire, but a heating wire!"

That's right, if a piece of metal with relatively high resistance is wound in a circle, it will form an electric heating wire. There is such a thing in the heating block.

This thing is the main culprit of dormitory fires, and several fires occur every year.

Although Captain Liu didn't understand the principle of electric heating wire, after listening to Li Donglai's explanation, his eyes widened: "These guys are so disgusting, they actually came up with such a method.

Fortunately, Director Li can follow you today. Without you, we would never have been able to find out."

Team Liu didn't mean to flatter him.

Although his team members are strong and capable and can run wild in a hail of bullets, their cultural level is not high. They are not even junior high school students. How can they understand physics?

The discovery of the electric heating wire is enough to prove that this is an arson. Director Liu and Deputy Director Wang must have no way to leave the security department.

but.

Everything must rely on evidence.

To find out why the two of them burned down the office requires actual evidence.

Team Liu frowned again: "Director Li, this electric heating wire can't explain anything. The two of them can deny this matter at any time. Besides, the financial officer Liu Xiaocui can also claim that he didn't know anything!"

"Kerosene, the key issue now is that we have to find the source of kerosene!"

Li Donglai said: "Burning the house like this shows that a lot of kerosene is needed. In this case, they need a container for kerosene! Now you immediately start the workers in the factory and look for iron boxes nearby.

something like that”

At this time, the workers should have gotten off work, but they were all thinking about the fire. Many workers were still in the factory, and they were now surrounding the outside of the office.

Team Liu walked out and said loudly: "Comrades, now Director Li has discovered a new clue that the bad guy probably threw the kerosene barrel somewhere when he was escaping. Now everyone is looking for the kerosene barrel!"

Hearing this, the workers nodded one after another

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Yes, this idea is correct, we should help!"

In just one day, the workers had already accepted Li Donglai.

Although it was getting very late, they still searched everywhere in the factory in the dark.

Seeing the workers busy everywhere, Li Donglai was a little worried.

If the enemy was very calm when escaping, he probably took the kerosene barrel with him.

But twenty minutes later, Li Donglai's worries disappeared.

I saw Wang Lan walking over with two consultants holding a big iron bucket.

"Director Li found it, found it, we found the kerosene barrel!"

"Where did you find it?"

"The person who threw the kerosene barrel was very cunning behind the hut next to it, and he was also very familiar with our factory. He knew that there was a trail behind the hut, and no one would pass by there on weekdays.

That’s why I threw the kerosene barrel there!”

Wang Lan said excitedly that she was happy to be able to help Li Donglai.

Li Donglai nodded and said, "Thank you for your hard work. It's already very late now. Let's do this. I just want to cook in the kitchen. You can stay in the factory to eat tonight!"

Generally speaking, in factories like third-tier factories, workers still need to spend money to eat.

Moreover, workers can only have lunch in the factory.

The workers suddenly became excited.

"Our Director Li is really generous!"

"Yes, yes, a meal costs a few cents!"

"If it were the former Factory Manager Liu, he could enjoy spicy food, but he would definitely not invite us to dinner!"

After the workers left happily, Li Donglai picked up the kerosene barrel and inspected it.

This kerosene barrel looks old and has the Mobil logo printed on it.

It should be from before liberation.

Kerosene barrels like this are relatively valuable in this day and age. Most people are reluctant to throw them away. Some people even regard them as family heirlooms.

Li Donglai handed the kerosene barrel to Team Liu: "Brigade Liu, you immediately use this kerosene barrel to find clues to the owner of the kerosene barrel!"

"Yes!" Team Liu agreed immediately.

It was already midnight by this time.

After Li Donglai handed over the task to Team Liu, he rode his bicycle to the courtyard.

Tomorrow is the day when Li Xiaomei leaves for the Northeast. He may not be able to see her off, but he still has to have a good time with her in the evening.

Li Donglai was riding his bicycle and had just arrived at the entrance of the courtyard.

He was stopped by the third uncle.

"Dong Lai, are you back?" the third uncle said with a smile.

When Li Donglai saw that his face was a little blue from the cold, he knew that the third uncle must have been waiting for a while.

He smiled and said: "Third uncle, what can I do for you?"

"It's not a big deal. You also know that my Yan Jiecheng has no job now. It's not a big deal for him to lie at home all day long. I heard that you have opened a new factory and you will definitely need manpower, so I want Yan Jiecheng to come to you."

Go to work in the factory!"

Upon hearing this, Li Donglai's face suddenly darkened.

"I'm sorry, Mr. Third, but our radio factory has strict requirements for workers, one of which is that they must not have a criminal record!"

After speaking, Li Donglai pushed the bicycle and left.
