When the word "four-dimensional code" came out of Ding Tang's mouth, several thoughts flashed in Tao Zi's mind. She immediately racked her brains to think about how such an important secret was leaked out.

Can it be said that Ding Tangtang tampered with his mobile phone?

But then she thought it was impossible. Tao Zi saw with her own eyes that Ding Tang destroyed the original receiving software.

And Tao Zi's mobile phone has always been in his hand. Ding Tang just wants to take it, but he doesn't have a chance to get it.

Even if Ding Tangtang got Tao Zi's mobile phone, it would be a heavy project to set up the software on her mobile phone. For a while, she couldn't get it out and didn't have the time.

Therefore, the assumption that Ding Tang tampered with her mobile phone is not tenable.

Tao Zi calmed herself a little. Then she asked quietly, "how do you know the four-dimensional code?"

"Didn't you ask clearly? I calculated it. I pinched my fingers for a long time just now, but you didn't see it."

Like Tao Zi, Ding Tang's face was calm, his tone of voice was normal, and he did not show any guilty conscience.

"You lie! I don't know your ways? They're all fooling people!"

Tao Zi's eyes suddenly became sharp: "Ding Tangtang, don't play tricks with me. Tell me the truth. How do you know about the four-dimensional code?"

Ding Tang was still a dead duck. "What's your relationship with me? We are iron porcelain friends. I can't deceive anyone?"

She made an innocent face, smiled bitterly and said, "I really calculated it. Who makes me a master? Magic calculation is my basic skill. Really, I really calculated it."

"Well," Tao Zi narrowed her eyes and said, "then tell me what's going on with this four-dimensional code? What's the principle and what's it used for?"

"This... The password is the password. It is to express what you want to say in a way that others don't know. Like those underground workers in the Anti Japanese war drama, don't they usually use passwords to transmit information."

Ding Tangtang combed his long hair with his fingers, and his bright big eyes whispered in his eyes: "I still know this common sense."

"You fart!"

Tao Zi suddenly pestled her shoulder. Ding Tang was startled. The steering wheel was biased. He didn't drive the car to the isolation belt: "Hey, what are you doing? I'm driving! You won't die with me?"

"You've made it clear to me. How on earth do you know? If you don't make it clear, I'll break up with you now!"

Tao Zi lost her temper. It was like a storm. Ordinary people really couldn't bear it.

However, Ding Tangtang had to carry it if she couldn't carry it. She also looked angry: "I told you everything I should say. What do you want me to say? I'm counting! Do you believe it or not?"

Tao Zi really had nothing to do with Ding Tangtang. Besides, she didn't want to get too stiff with her, so she had to suppress her anger and point to Ding Tangtang's nose:

"OK, I'll believe you this time. If you let me know what you did to me. Hum, that's the end of our friendship!"

"How can I say hello? You're just too suspicious. I've been dating you for so long, and you don't know who I am? I can't do anything to you. What's the relationship between us? Can I be so heartless?"

Ding Tangtang secretly breathed a sigh of relief. Wei was wronged and muttered, "hiss, what do you think?"

……

Lancheng is adjacent to Yicheng and is located in the southeast corner of Yicheng. The two cities are only more than 100 kilometers apart. In less than two hours, Tao Zi and his group of three cars came to Lan City.

Lancheng is a city based on heavy industry. Many national key factories and mines were gathered here many years ago.

Today is different from the past, because of economic transformation and market changes, those big factories and mines have either moved out of the urban area or become depressed day by day.

The rows of factories on both sides of the road have either been abandoned or lifeless. It seems that few people work in it.

Driving eastward, I finally saw a large plaque across the road, which read "Zhengrong Petrochemical Group" in big red characters.

Most of the large trailers driving on the road are loaded with dozens of tons. With the hurricane, they rumble by.

The road was dusty, and the trees on both sides of the road were dusty. Those factories became taller and more majestic. There are also some large steel cans, like rows of enlarged thermos cups, piled up disorderly in the big wall.

Tao Zi came to this place for the first time. Looking at the iron guys who are comparable to high-rise buildings outside the window, she felt very curious and couldn't help asking Ding Tangtang: "these things are so big. What are they used for?"

"You ask me? How do I know?"

Ding Tang glanced at Tao Zi and said, "but with these things alone, I think Zhengrong group is really strong. You see, we have gone so far that we haven't even reached the front door of the factory."

Ding Tangtang is right. The area of this factory is so large that it is almost half the area of Yicheng from beginning to end.

More than ten minutes later, a gate appeared in front. Liu Jun's Audi A6 stopped at the door and was stopped by two security guards.

Liu Jun got out of the car and explained the situation to the security guard. The security guard didn't enter the oil and salt and shook his head at Liu Jun.

"What's the matter? Didn't uncle Liu make an appointment with Mr. Niu?" Tao Zi couldn't sit still and wanted to get off and have a look.

"Sit down first," said Ding Tangtang. "It's no use for you to go down. The security guards here are cattle. They don't have certificates. You won't let you in even if you tell the dragon to ask others. I learned it last time."

"Aren't we here in vain?" Tao Zi looked back at the nanny car and thought she had recruited Liang Yi. She just went back home. Isn't she too shameless?

"Don't worry. It's their problem that they won't let them in. It has nothing to do with us. They will regret it at that time."

Ding Tang said with confidence.

Tao Zi looked at Ding Tangtang's eyes and guessed that she must be playing some evil way again. She asked, "that cow won't count on you, too?"

"Well, I took him as an apprentice." Ding Tang said with his head raised as if he had a status.

"If so, Niu should always ask you out the first time? How can it be delayed until now?"

"I'm not vulgar. I haven't shown my true face, so he doesn't know who I am."

When Ding Tangtang said this, he smiled mysteriously: "but I told him something I shouldn't say, otherwise with his big boss, it's impossible to promise to see us."

"Said something you shouldn't have said?" Tao Zi certainly understood what Ding Tangtang said. She must have exposed others' old background.

With a helpless face, she earnestly taught Ding Tang with a bitter smile: "you, you still have to keep some integrity in life and work, and don't cross that node. At that time, no one can save you."

"Don't worry, I know what to do." Ding Tang saw that Tao Zi said good words and was very moved. A faint smile hung on the corner of his mouth.

While talking, Liu Jun walked over and knocked on the window. Ding Tang lowered the window and asked, "uncle Liu, what's going on?"

Liu Jun didn't expect Tao Zi to sit inside. He nodded at her and said, "President Tao, are you here too?"

Tao zichong smiled at him. Liu Juncai said, "Niu suddenly changed his mind. I called him. He asked me to go back and didn't want to see me."

"Yeah, hey, this cow is fat enough?" Ding Tang first gnashed his teeth and said to Liu Jun, "uncle Liu, you go back to the car and sit for a while. I'll call him. I'll see what his cow is!"

Liu Jun ran with Ding Tangtang for a while. He also saw the energy of the Yellow haired girl. He smiled and said, "well, I'll wait in the car first." he waved to Tao Zi, and then turned to the Audi A6.

Ding Tangtang took out his cell phone and dialed two consecutive calls. No one answered them. She was more and more angry: "Hey, Niu, you dare to follow me!"

Ding Tangtang sent another wechat to the other party. This move was really effective. Soon her mobile phone rang.

"Mr. Niu, you're really good. Dare you refuse to answer my phone? Don't you want to mix up?" Ding Tangtang changed his usual style of trendy women and became full of ruffian flavor, making it like mixing society.

The cow in the mobile phone always seemed to say something. Ding Tang angrily scolded: "anyway, I don't care. You play routine with me. I can't hide it for you. See which of us will be better then!"

The other party seemed soft, and her voice was as low as a mosquito humming. Tao Zi sitting next to her could only hear a few words, and could not even form a sentence at all.

"OK, I won't say more. You can do it." Ding Tangtang hung up his cell phone, changed his seriousness and smiled at Tao Zi.

Tao Zi asked curiously, "what do you hold on to him? Is he so afraid of you?"

"Actually, it's nothing," Ding Tang didn't want to say. Seeing Tao Zi's persistent questioning, he couldn't help showing off:

"That Niu is the son-in-law of a big man in the province. He has always been supported by his father-in-law. Otherwise, he can't be the general manager of such a big factory with his three legged Kung Fu.

"But, man, once he has the power and money, he wants to stay out and mess around. But he is different from other rich men. He has no autonomy. Once his wife knows that he secretly raises a junior, he will have to be completely scrapped.

"So this guy ran over and asked me whether it was OK or not and whether his wife would find out.

"I like to watch the excitement. I told him on the spot, OK, what's wrong? As long as I do it carefully, my wife can't find it.

"After listening to my words, this Niu became brave immediately. He bought a villa here in Yicheng and raised a junior.

"Of course, he can't escape this shit. I often remind him when I have time."

Tao Zi shook her head: "Ding Tangtang, what's your name? You're called extortion!"

"Did I blackmail? Did I blackmail? I didn't ask him for a penny. How did I blackmail?"

Ding Tang put on a look of innocence.

At this time, the security guard in front of him had let go. Ding Tang smiled and said, "look, I'm on my horse, one for two!"
