A powerful country in scientific research

Zhao Qiang took his two brothers and went directly to the private room where Su Ran and others were.

Obviously everyone in the room had been prepared by Su Ran, so they were not surprised to see Zhao Qiang and the other two.

Zhao Qiang: "Comrade Su, our people have locked the two doors of the hotel, and there are people guarding each door. They will not let anyone out."

Su Ran nodded, "Comrade Zhao, thank you for your hard work."

With Zhao Qiang and the others around, the person who poisoned the food would not be able to escape, and Su Ran felt much more at ease.

Zhao Qiang smiled slightly, "This is our job, you're welcome." He glanced at the other people in the private room and said in a deep voice, "Comrades, I believe everyone knows what happened in the hotel. Now we need to conduct some investigations, so everyone can only stay in this room for the time being. Please cooperate with our work."

Everyone in the room nodded in understanding.

They all guessed that this was aimed at Su Ran. After all, they were not worth others mobilizing so much force to murder them.

When they thought about how they had just urged Su Ran to eat that dish, they felt so regretful.

They were so active just now that outsiders must think they are suspicious. They must find the murderer, otherwise it will be difficult for them to clear themselves of suspicion.

But they are just ordinary people and cannot catch the murderer. The only thing they can do now is to cooperate with the police to find out the truth of the matter as soon as possible.

Seeing that Su Ran was fine, Zhao Qiang brought his men downstairs again.

The people who are most suspicious and have the greatest chance of poisoning are those in the kitchen, so we have to ask them first.

......

At the same time, on the first floor.

The Public Security Bureau people arrived at the gate.

The leader looked at the closed door of the hotel and frowned.

"Did you call the police here?"

"Yes, Captain Wang."

Wang Zhifeng strode to the door and knocked on the hotel door.

The door opened and a sturdy man opened it.

"Hello, are you the ones who called the police?" Wang Zhifeng asked, looking at the man in front of him sharply.

Wang Zhifeng looked at his figure and posture and guessed that he must have been a soldier.

He was a little confused as to why a man who had been a soldier and trained in the military was here now, but he didn't say anything.

Zhao Qiang's subordinate Li Sheng nodded.

Wang Zhifeng: “What happened?”

"Someone poisoned me." Li Sheng answered simply.

Wang Zhifeng's face changed, his brows knitted, and he continued to ask: "Where is it? Are you sure? What kind of poison? Are there any casualties?"

Li Sheng: "No, we found it in time, there are no casualties."

Hearing his answer, Wang Zhifeng's frown gradually relaxed and he breathed a sigh of relief.

"Are you the security guard here?"

Li Sheng shook his head and took out his ID in a corner where no one could see.

When Wang Zhifeng saw the certificate, his expression became serious.

They turned out to be comrades from the National Security Department. They would not appear for no reason. There must be some important people or things here.

"Comrade Li, do you have a mission here?" Wang Zhifeng knew he shouldn't ask, but after all, a case happened today, and if he wanted to help, he had to know something.

Li Sheng explained simply: "There is a mission. The person we are protecting is having a meal upstairs. She was poisoned. Our boss is in the kitchen. I will take you there."

Wang Zhifeng nodded, "Thank you for the trouble."

When I followed Li Sheng to the kitchen, Zhao Qiang was asking questions.

Li Sheng walked over and whispered in his ear: "Captain, people from the Municipal Public Security Bureau are here."

Zhao Qiang nodded, said a few words to the people beside him, and followed Li Sheng in the direction where Wang Zhifeng was.

The two walked up to Wang Zhifeng, and Li Sheng introduced him: "Captain, this is Captain Wang from the Municipal Public Security Bureau. Captain Wang, this is our captain, his last name is Zhao."

Zhao Qiang nodded to Wang Zhifeng, "Hello, Captain Wang."

"Hello, Comrade Zhao."

Zhao Qiang: "Captain Wang, thank you for your hard work today."

Wang Zhifeng smiled slightly, "Comrade Zhao, you are too polite. If a case happens in this area, we should be responsible. Comrade Zhao, can you tell me what happened?"

Zhao Qiang nodded and briefly introduced to Wang Zhifeng what happened after they arrived at the hotel. He combined what he had just asked and what he saw, and his account was quite detailed.

He also talked a little about the situation at the blockade, the number of people at the scene and the situation.

After hearing this, Wang Zhifeng frowned and asked, "Are you sure it was poisoned?"

Zhao Qiang pointed to a dead rat not far away and said, "It's confirmed. The poison is very strong and the symptoms occurred almost immediately."

Wang Zhifeng nodded heavily, "Comrade Zhao, what stage have we reached? What do you need us to do?"

When it comes to people under key state protection, they are not responsible for it. This matter mainly has to be done by comrades from the national security department, and they provide assistance.

Zhao Qiang: "I haven't asked anyone outside yet."

Wang Zhifeng suggested: "Okay, then leave that to us."

"Okay, trouble."

Zhao Qiang did not refuse. There were too many people at the scene, and the people he brought might not be enough, so he still needed the help of the police.

After leaving the kitchen, Wang Zhifeng went to the hall outside.

"Hello everyone, I'm Wang Zhifeng from the Haishi Public Security Bureau." Wang Zhifeng walked up to the crowd and looked at the scene seriously. "A serious criminal case has occurred in the hotel. Because the situation is serious, we ask everyone to cooperate with the investigation. We need to take notes, and I hope everyone can answer the questions truthfully."

Everyone looked at so many people in police uniforms, and thought about Zhao Qiang's strength and his wooden cannon just now, and they all cooperated very well in taking the statement.

After arranging the people to take the statement, Wang Zhifeng and others started the investigation immediately without delay.

Wang Zhifeng and several people began to search the restaurant carefully and checked the food, kitchen, private rooms, etc., but found nothing.

Wang Zhifeng was a little disappointed. He walked to Zhao Qiang and asked in a low voice, "Have the people in the kitchen been searched?"

Zhao Qiang: "I searched it, but found nothing."

Wang Zhifeng sighed in his heart. This was going to be troublesome.

Zhao Qiang glanced at him and asked, "Did you find anything?"

Wang Zhifeng: "No, I searched the entire hotel and didn't find it."

Zhao Qiang nodded. This was within his expectations.

Anyone who dares to do such a thing in broad daylight must be very careful and would not leave any evidence.

After Zhao Qiang and others asked the people in the kitchen, they went upstairs. The people in the two private rooms had not been asked yet. They were also suspects and could not be left behind!

After recording the statements, Zhao Qiang and Wang Zhifeng took the suspects or those who had direct contact with the food to the police station.

This matter involves human life and is related to people who are under key state protection, so it must be investigated thoroughly.
