That night, all members of Team O of the Headquarters, except for Fang Yiwei and Chen Jin who were watching Superintendent Zhang outside, worked overtime to publicize that they were sorting out the files on the bank vault robbery case.

People in several other groups looked at it and felt a little disdainful in their hearts.

Although this case was originally handled by four groups, since the four groups were wiped out, several other groups have participated in the investigation.

Everyone is aware of the difficulty of the case, and with many key clues missing, the case can theoretically be considered an unsolved case.

So now, seeing that the four groups are doomed to go about their business without results, it is hard to stop them, but it is inevitable to feel gloating about their misfortune.

Soon it was evening, people who were supposed to get off work had almost left, and all the takeaway meals Guan Zu ordered had arrived.

Looking at the takeaways that filled several desks in front of them, even though they knew it was for action, everyone still couldn't help but drool.

Huang Qifai even lowered his head and took a deep breath to smell the aroma of the vegetables. Then he leaned back in his chair and thought about it for a while, then curiously turned around and asked Guan Zu beside him.

"Azu! Which takeout place did you order from? I have been a policeman for so many years, and this is the first time I discovered that takeout food can be so delicious!"

"Lu Yulou specially asked their master to work overtime to make it. Once it was done, it was delivered directly.

Sir Huang, it's your turn now! When the case is over, I'll invite you all to have a good meal, and don't let anything go wrong tonight." Guan Zu answered while walking to Huang Qifai with a smile, asking him to hurry up.

Go call someone.

Huang Qifai is worthy of being a good old man in the police force for decades. He is very popular. He has attracted all the people who worked overtime in the O record.

As soon as everyone entered the office hall of Group 4, they were immediately attracted by the takeout on the table. The aroma that hit their faces was much stronger than the takeout they usually eat.

"Everyone has worked hard overtime. Today we are treating Sir Guan. Don't be polite. Don't look at it as just takeout. These dishes are usually hard to eat." Huang Qifa not only invited people over, but also greeted him warmly.

When the others heard that it was Guan Zu who was inviting guests, their eyes lit up.

In the entire police headquarters, he is the only one who can ride a bull to work.

The roar of the engine can be heard by everyone upstairs.

Moreover, his background has been circulated in O Diary for a long time. Although it is not too detailed, everyone knows that this kid's family has money and is very rich.

Since it's a treat for a rich second generation, the things definitely won't be too ordinary.

So everyone sat down one after another, and Huang Qifa started to behave in a decent manner and started chatting with everyone.

Seeing that the situation was almost stable, Guan Zu quietly gave Chen Guorong a wink.

They saw Chen Guorong, Ma Jun and Watson quietly withdrawing from the dining crowd without leaving a trace, and walked toward Superintendent Zhang's office.

Wei Jinghao quietly took out his phone and observed everyone carefully.

As long as someone shows signs of leaving, Huang Qifa and Guan Zu will step forward to hold him back. If there is a situation that cannot be held back, Wei Jinghao will call Chen Guorong and the others.

Everything went according to plan in an orderly manner, but unfortunately after waiting for a long time, no one came back.

Guan Zu raised his hand and looked at his watch, thinking to himself, "This must have happened again. The original plan was to end the battle in five minutes at most, but now it's almost ten minutes."

Huang Qifa also noticed something was wrong and looked up at Guan Zu, seemingly asking what to do now.

Guan Zu had no choice but to use the restroom and asked Huang Qifai to greet everyone, then quickly walked to Superintendent Zhang's office.

Arriving at the door of the office hall of Superintendent Zhang and his team, Guan Zu saw that Watson was still hiding at the door to keep watch, and his heart finally dropped halfway.

Without saying anything else, he gave Watson a look that kept him on the lookout and went directly into Superintendent Zhang's office.

In the office, Chen Guorong and Ma Jun were squatting in front of the iron cabinet, staring with big eyes.

Seeing that the cabinet door had been opened, Guan Zu said directly, "What's going on? Why did it take so long? Is the gold in it?"

Someone spoke behind them, and the two of them were startled at first. Then they realized it was Guan Zu, and Chen Guorong said with a wry smile.

"Sir Guan, come and see for yourself."

When Guan Zu took a closer look, he was dumbfounded. He saw that there was actually a safe in the iron cabinet of the superintendent in this chapter.

"Open it? You can even open the office door, so this should be no problem, right?" Guan Zu asked tentatively.

"Sir Guan, this is a safe!" Chen Guorong didn't say much, but looked helpless.

"Made, come and help me lift this thing up." Guan Zu took a closer look and found that the safe was placed in an iron cabinet and was not integrated with the cabinet.

"No way! Sir Guan, if we take the cabinet away, wouldn't that expose the truth?" Ma Jun heard that Guan Zu wanted to move the safe directly and quickly persuaded him.

"Stop talking nonsense, come here and try it. How much does this safe weigh? Generally, a safe of this size would weigh more than two hundred pounds." As soon as Guan Zu finished speaking, Chen Guorong and Ma Jun also reacted.

Safes in offices are generally used to store important documents or confidential files.

Even if it is fully stuffed, it will only weigh a few dozen kilograms at most, but if it is filled with gold, it will be different.

Gold is a very heavy thing, and the amount of gold that was stolen was more than two hundred kilograms.

Including the 100 for the safe, it will be almost more than 300 kilograms. Compared with the safe for storing documents, the difference is huge.

Sure enough, although the position was a bit crowded, it was not easy to exert force. But the three of them were all in good shape, so they all used their full strength to lift the safe a little.

"That's enough! Remember this feeling, let's withdraw!"

Although they only raised it slightly, Guan Zu and the others were still blushing.

However, the three of them knew for sure that what was in the safe would definitely not be documents.

After taking out his cell phone and carefully taking photos of the safe, Guan Zucai led the three of them back to the supper scene in a hurry.

Maybe it was because the late-night snack was so delicious that everyone was focused on the food. Until they came back, no one noticed that someone had left quietly in the middle of the meal.

After the supper was over, everyone returned to their respective turfs, and Huang Qifa was the first to run into Guan Zu's office unbearably.

"How is it? Have you gained anything?" Although the good old man is afraid of trouble, he still has a certain enthusiasm for solving cases.

"Yes, there is something wrong with the safe in Superintendent Zhang's office. It is too heavy."

After Guan Zu finished speaking, he summoned all the remaining team members.

"The work will remain the same tomorrow. Those who should be kept under surveillance will continue to watch. Chen Guorong and Ma Jun, you two will go with me to buy a safe."

Guan Zu decided to use the most primitive method, buying a safe of the same style and putting different things in it to test.

Although it may be tiring and the three of them have to lift it repeatedly to feel it, Guan Zu believes that there is a high probability that a safe as heavy as Superintendent Zhang contains gold.

Thinking of this, regardless of the fact that it was late at night, he directly called his friend Liu Tian.
