"No need to send it, you can go back and wait for the notice first. Officer Wang declined Zhao Heng's send-off.

Gu Chen, on the other hand, took the collected saliva samples, and Lu Weiwei left the accounting firm with Officer Wang.

As soon as he walked not far away, Officer Wang suddenly turned his head and said, "Gu Chen, you ......"

"I'll stay here and ...... Continue to monitor Zhao Heng's every move, is that so?"

Before Officer Wang could continue to finish, Gu Chen had already finished answering for him.

Officer Wang smiled: "That's what it means, I didn't expect you to know?"

"Don't look at who Senior Brother Gu is?" Lu Weiwei also shouted.

Zhao Heng flipped through the ledger and licked his fingers with his tongue eighteen times a minute, just this kind of subtle operation, Gu Chen could know, could he not know Officer Wang's careful thoughts?

In fact, if you don't catch Zhao Heng, you also want to catch him, in order to let him show his feet.

After all, handling a case is a long job, and you must not rush it.

In handling cases, if you only rely on the testimony provided by Zhao Heng and want to close the case early, it will often lead to hasty or omission of details.

The police have always pursued the rate of solving cases, and if there is a mistake in the direction of the investigation of the case and important clues are missed, it is easy to cause unjust, false and wrongful cases.

So in the final analysis, not catching Zhao Heng is actually a set of tricks.

"Senior Brother Gu, you stay here first. Lu Weiwei smiled and said, "After we go back and compare Zhao Heng's saliva sample with the saliva sample on the previous threatening letter, we will inform you of the next move." ”

In fact, Lu Weiwei preferred to stay and squat with Gu Chen.

However, Officer Wang was carrying a huge amount of dirty money, and according to the usual practice, at least two people had to be in charge of escorting it.

"Don't worry, I'll leave it to me. Gu Chen took out a casual suit from the police car, then changed the police uniform, and said, "If there is a situation, I will inform you as soon as possible." ”

"Very good, I'm relieved to have your words. Officer Wang was still quite relieved of Gu Chen, he looked down at his watch, and said, "Remember, we are still 36 hours away from the final deadline for solving the case." ”

Officer Wang reminded him again that he is now ...... I have a headache when I see the time.

It may be because the fish has been salted for too long before, so I don't feel this sense of urgency.

And now, he suddenly dared to grab a task with the second group, not to mention whether he could solve the case, just looking at Xiao Yang's depressed face, Officer Wang felt that his life had reached its peak, and he even felt comfortable that he had never had.

After Officer Wang drove away, Gu Chen looked at his watch, it was also lunch time.

He casually found a pizzeria diagonally across from the accounting office and prepared a pizza for lunch.

At this time, it is the peak dining season, and there are many customers who come to the pizzeria to eat.

As soon as Gu Chen finished ordering, he quickly found a place by the window and sat down first.

Here, he can clearly observe the accounting firm.

It didn't take long for a male waiter to come to Gu Chen with two pizzas and said politely:

"I'm sorry sir, the 9-inch pizza you want is gone, we changed two 5-inch pizzas for you, the boss said, according to the 9-inch pizza charge, and give you one inch for free." ”

"Oh, and this kind of good thing?" a fat man sitting next to Gu Chen suddenly had his eyes sparkle when he heard this.

And several other people around also turned their heads to look at them, and threw away envious glances one by one.

Thinking that there are such good things, ordinary people have long been happy in their hearts, and they promise that it is certain.

But Gu Chen shook his head and refused: "You know the area of the circle...... How should it be calculated?"

"This ...... Is there anything wrong with this?" The waiter was momentarily stunned, looked at Gu Chen blankly, and said in his heart, what are you asking me for?

Gu Chen smiled bitterly and said, "The area of a circle is equal to the square of the radius, multiplied by pi. ”

The waiter was stunned.

Several customers around were also stunned.

Gu Chen continued: "If you use this formula to calculate, then the area of this 9-inch pizza is about 63.585 square inches, and the area of a 5-inch pizza is about 19.625 square inches. ”

"Yes...... But what does that mean?" the waitress continued to bewilder.

"The sum of the area of two 5-inch pizzas is about 39.25 square inches. Gu Chen sneered: "So, even if you give me three 5-inch pizzas, it is not as large as my 9-inch pizza, but you actually said that you will give me one inch for free?"

Speaking of this, the waiter was dumbfounded on the spot, and he was at a loss for a while.

He didn't expect it, he really didn't expect it.

This young man, eating a pizza, even moved out of the formula, this is especially because there are formulas everywhere in life!

However, the owner of the pizza shop naturally knows these cats, but there are usually few real customers, that is, he has not found it.

But since Gu Chen gained a specialized-level memory, the knowledge in his head has been increasing day by day.

He also wants to keep a low profile, but his strength doesn't allow it, and he has more eyes than others in everything.

"I'm not afraid that the diners are too powerful, I'm afraid that the diners know mathematics, physics and chemistry, this kid is amazing!" A middle-aged man sitting next to him suddenly gave a thumbs up.

And the other diners also quickly became hotly discussed.

"Well, knowledge is the only way to be satisfied. ”

"If it's me, then it's troublesome, I won't count, haha, give an inch, I will definitely be happy, but I will suffer again. ”

"I'm afraid you haven't seen anyone who studies medicine, eat a roast chicken, you can put together a complete skeleton, and you know which piece is missing. ”

"If you are not good at math and even eat a pizza, you will be pitted, this is a master meeting a master. ”

"Cultured people just eat more. ”

"How can you feed your brain cells if you don't eat much?"

"Got it, don't eat pizza. ”

......

Many people around were about to laugh and cry, and their hearts said that there could still be this kind of operation?

Sure enough, when the top student goes out, he suffers?

In fact, while Gu Chen was ridiculing, his eyes never left the accounting firm.

His drunkard's intention was not in pizza, but in Zhao Heng.

The heart said that at this time, it was time to come out to eat, right? Why didn't there be any movement?

On the other end, seeing the stalemate of the scene, the backstage boss couldn't sit still, and hurriedly beckoned to the waiter.

The waiter immediately left the scene with interest.

"Boss, I'm afraid this kid isn't here to smash the field, right?" said the waiter with a bitter face.

The owner of the pizza shop, whose scalp was also numb at the moment, muttered to himself: "How can this be? I obviously used this routine to play with many customers, but why didn't this kid fall for it?"

"What then?" asked the waitress again.

The boss frowned and said, "Go and bring him two more 5-inch pizzas and tell him to shut up." ”

In the end, under the compromise of the boss, Gu Chen got two more 5-inch pizzas.

Taking advantage of his strength, Gu Chen is serious.

After eating the pizza, it was already two o'clock in the afternoon.

The staff of Zhao Heng's accounting firm had basically come out to eat, but they didn't see Zhao Heng's shadow.

"Is this guy going to run away?" Gu Chen couldn't help but wonder, but looking back, this idea ended here.

Because the streets are full of surveillance, Zhao Heng wants to run, unless he is a thunderbolt.
