Lu Yao continued: "I suggest that in the future, whether it is a noodle restaurant or a food processing factory, it is necessary to purchase ingredients from qualified suppliers. Every bag of flour, or every pound of rice, and every barrel of cooking oil they supply to us, must have the name and number of the production place, processing plant, and control food safety from the source. ”

"Okay, this afternoon, I'll go to the oil wholesale department, the flour and rice processing factory, to have a look and implement this matter. Liu Jing said.

They returned to the main store of the noodle restaurant, and after a brief lunch, Lu Yao immediately rushed to the machinery and equipment manufacturing factory. Liu Jing first went to the bank to coordinate the funds, and then went to handle other things.

When Lu Yao came to the manufacturer, he was very happy to see that more than a dozen food processing machines had been manufactured. After reconfirming the model and quantity of the machines that needed to be manufactured in the later stage with the factory director and Li Gong, he immediately rushed to the site of the ruins of his food company in Honghu No. 1 Industrial Zone.

The crown car he was riding in drove into the industrial park and saw Lao Wang sitting with several security guards chatting. When they saw Lu Yao getting out of the car, they all gathered around to say hello.

"Lao Wang, when did the police finish investigating the scene?" Lu Yao asked.

"At 10 o'clock this morning, they were all evacuated, and the scene was unsealed. Lao Wang replied.

Lu Yao looked at the large ruins and stood for a while before stepping on the cement blocks that had been burned by the fire and stumbling towards the location of the generator room, followed by several security guards.

When they came to the location of the computer room, they saw that it had been excavated, and there were piles of debris all around, and Lu Yao asked, "Is this excavated by the police?"

"Yes, last night, 10 police officers dug here all night, probably to find out the cause of the generator fire and explosion. They also loaded a cart of debris from the generator and pulled it away. Lao Wang said.

Lu Yao stopped talking, he walked around the neighborhood, and then returned to the location of the generator room, bending down to take a closer look, and turning the cement blocks from time to time.

He looked at the ruins for more than an hour, but found nothing. After saying goodbye to several security guards, he got into the car and left the scene.

Half a month later, at 8 a.m. on Monday, the construction team of the rebuilt plant entered the site and began to clean up the waste residue. Lu Yao came to the construction site in advance and directed the construction.

At four o'clock in the afternoon, the forklift drove to the location of the generator room, and after shoveling up a few cement pillars, Lu Yao instructed the forklift driver to shovel the waste residue in other places first. He grabbed a shovel and began to shovel the debris underneath the machine room.

At eight o'clock in the evening, all the construction workers left the site, he asked the security guard Xiao Song to light it with a flashlight, and he continued to shovel the remaining waste residue.

After ten o'clock in the evening, he rummaged through all the waste residue near the generator room, but he couldn't find what he was looking for.

He put down the shovel in his hand, sat on a cement block, drank water, and asked, "Xiao Song, one of the two young men who were about to enter the factory at that time, one of them was wearing a shoulder bag, he was Japanese, and he never spoke, right?"

"Yes, he's probably about twenty-three or fourteen. Both young men were thinner. Xiao Song replied.

"When you and Lao Wang went to the door on the right side of the van and argued with the two men, did the Japanese man stand next to the van?" Lu Yao asked.

"No, he got into the car through the left door when they were about to leave. At that time, he closed the car door very hard, and the whole car was shaking. Xiao Song replied.

"Where was that Japanese man during the previous period?" Lu Yao asked.

"Not paying much attention, he should have been standing at the gate all the time. It may have been impatient to wait before he rushed into the car. Xiao Song replied.

"In other words, you can't be sure that he has been standing at the gate of the factory, right?" Lu Yao asked.

"At that time, Lao Wang and I had a heated argument with the other two men, and Lao Wang and the driver almost made a move, so we didn't have time to pay attention to the Japanese man. Xiao Song replied.

"Did you and Lao Wang tell the police about this situation?" Lu Yao asked.

"No, the police didn't ask. Xiao Song replied.

"Can you recall this situation again and see if you can remember anything?" Lu Yao finished speaking, reached out and took the flashlight from the other security guard, and checked it on the ruins again.

When he forcefully moved a piece of cement block, he saw a small colored stick underneath that was particularly eye-catching. Although it was deformed by the cement block, and two places were broken, it could still be seen that it was somewhat out of place with other waste residues.

Lu Yao squatted down, carefully held the broken small stick in his hand, and looked at it carefully, and found that it was hollow. He sniffed it with his nose again, his brows immediately furrowed, and he immediately shouted, "Xiao Song, come here." ”

Xiao Song and another security guard came to him, he raised his little stick and asked, "What do you smell like here?"

After Xiao Song and another security guard smelled it, they said in unison: "The smell of gunpowder!"

"Are you sure?" Lu Yao asked.

"Mr. Lu, both of us have been soldiers, and we are very familiar with this smell, which is definitely the smell of gunpowder. Xiao Song said. Another security guard was also nodding.

"You guys help me find a piece of plastic paper nearby, and I'm going to keep this stick and give it to the police. You protect this area and don't let anyone come near until the police come. Lu Yao said.

He took a piece of worn-out plastic paper from Xiao Song's hand, wrapped the small stick, and immediately walked to his crown car.

He got into the car, immediately picked up the Motorola, and quickly dialed a number to go out. After the phone was connected, he said: "Hello Brigade Yao! I'm Lu Yao, are you in the brigade?"

"I'm out on a mission, what's the matter?" said Brigade Yao on the phone.

"Team Yao, just now I found a small colored hollow stick in the waste residue under the generator room. I confirmed with two former security guards that this little stick had been filled with gunpowder, and I wanted to show it to you. Lu Yao said.

"Found in the ruins of your burned-out factory, right?" asked Brigade Yao.

"Yes!" replied Lu Yao.

"I said that you kid is really a criminal investigator! Okay! Don't leave the scene, I'll call Officer Zhu who is in charge of this case immediately, and he will come to look for you." After Yao finished speaking, he immediately hung up the phone.

Half an hour later, a police car flashed its lights and drove directly to Lu Yao's crown car and stopped. The doors on both sides opened at the same time, and four policemen got out of the car together, and one of them shouted: "Lu Yao!

Lu Yao was still dozing off in the back seat of the crown car, and the driver Wen Yuan hurriedly pulled the car door to wake him up. He opened his eyes and saw the police car and the police, quickly got out of the car, and asked, "May I ask who is Officer Zhu?"
