The teacher was a little annoyed and slammed the book in his hand on the desk.

"Smack!"

The heavy voice woke up many of the sleeping students in the class, and they all looked at the podium in confusion, only to see the history professor who was blowing his beard and glaring.

The professor is old, and he knows that time is gone forever, and it is difficult to buy an inch of time, and he sees himself slowly aging every day, and he is very unaccustomed to the fact that students sleep in school.

He thought that Ye Cheng, a student, was a new transfer student, so he wanted to make an example of the monkey and give a life education lesson to these students who were not studying well.

The old professor exhaled heavily, and said in a deep voice: "You don't have to make excuses, I'll change the simple question." What is Flying Money?"

Ye Cheng's gaze rose slightly, as if he was thinking.

When the old professor saw his arrogant appearance, he became a little angry again, slapped the table heavily, and said, "Does anyone else in the class know?"

Ye Cheng shifted his gaze to the old professor, stared into his eyes, and said lightly, "I haven't answered yet." ”

"You know?"

"I was just thinking about how to explain it in the shortest possible words. ”

"Help me, hmph! I'm asking you to answer, not to answer me!" corrected the old professor.

Ye Cheng said lightly: "Flying money, in today's terms, is a kind of bank card. ”

The old professor was slightly stunned, but he didn't expect this student to really answer, and asked again: "Is this kind of thing meaningful?"

Ye Cheng continued to reply: "The generation of flying money was just as a way of trading, merchants were trading at that time, and they couldn't bring a lot of money, so this kind of thing was produced, but the main reason was that there was a shortage of money at that time, and it was not allowed to bring it, so it could only be used in this way, so it could not replace coins." If there is any meaning, it is to set an example for the appearance of coins in the future. ”

The old professor thought for a moment, then told him to sit down.

Ye Cheng didn't sit down, and continued: "The flying money thing is not as simple as it is recorded now, and there is actually a huge conspiracy in it. ”

The old professor frowned, suddenly became a little interested, and said, "What conspiracy?"

Ye Cheng smiled faintly, as if he was teasing a child, and said, "I'll answer this time, so can I help you answer?"

The old professor was slightly stunned, his face suddenly turned a little red, and then motioned for him to sit down, this kind of behavior of asking students for advice was a little unacceptable to him.

After Ye Cheng sat down, he began to listen carefully to the old professor's continued lessons, he was too sleepy just now, and fell asleep in a daze, and now that he was awake, in order to give the old professor a face, he couldn't continue to sleep.

Fortunately, there are only ten minutes left before the end of class, and it will be over quickly.

After the class bell rang, Chen Tianzhen quickly ran over and asked curiously, "Big brother, what kind of conspiracy is that flying money you are talking about?"

Ye Cheng smiled and said, "Are you so interested in history?"

Chen Tianzhen nodded vigorously and said, "Yes, so tell me quickly!"

Ye Cheng reached out to mess with her hair, rubbed it vigorously, like a chicken nest, and said, "I'll tell you when we meet in the future, let's go home first, I have something else to do at night and need to be separated." ”

Chen Tianzhen smiled slightly and asked, "What are you going to do?"

Ye Cheng thought for a while and said, "A somewhat dangerous place, so I have to settle you down first!"

Ye Cheng and Chen Tianzhen took a taxi back to the villa, before entering the door, Ye Cheng released his internal force and sensed the situation of the entire community, at this time there were more people in the community, and he took a little time, but fortunately, there were no outsiders in the community, and it was safe.

He took Chen Tianzhen to a villa next to him and knocked lightly on the door.

Within ten seconds, the door opened, and a well-dressed woman appeared behind it.

Ye Yurou's beautiful eyes stared at the man at the door, and the girl who often took him in and out of the community, there was a slight gap in her heart.

"Hello, is there something wrong?" Ye Yurou asked.

Ye Yurou pretended not to know Ye Cheng, this is also what Ye Cheng had explained before, and now Ye Yurou is an ordinary resident, with no identity and no background, only in this way can she not hide her eyes.

Ye Cheng said: "This is my sister, I have something to go out, can you help me take care of her?"

Chen Tianzhen looked at Ye Yurou with a cute face, looking at this mature and steady woman, and didn't know what she was thinking.

Ye Yurou nodded and said, "Then when will you come back?"

Ye Cheng thought for a while and said, "Before about nine o'clock, you remember to stay in the house with her and don't go out." ”

Ye Yu responded softly, then took Chen Tianzhen by the hand with a smile, took her into the house, and did not forget to praise her: "What a cute girl, how old is this year?"

Ye Cheng watched these two people enter the house, and told Chen Tianzhen again: "Naive, remember, don't go out of the house." ”

After speaking, Ye Cheng turned around and left, preparing to take a taxi to Xu Shanshan's house.

Ye Yurou turned around, closed the door, locked it tightly, and then looked at Chen Tianzhen with a smile and said, "Are you called Tianzhen?"

Chen Tianzhen shook his head and said, "No, my name is Chen Chang, it's just that the eldest brother likes to call me naïve." ”

Ye Yurou covered her mouth and laughed, and said, "You girl is so cute. ”

Chen Tianzhen tilted his head slightly, with puzzled face, and asked, "You and your eldest brother know each other, why don't you recognize each other?" Are you hiding it from me?"

Ye Yurou was stunned for a moment, her body paused slightly, the smile on her face gradually disappeared, and she said to Chen Tianzhen seriously: "What are you talking about?"

Chen Tianzhen ignored her, pursed his lips, sat on the sofa, and played with his mobile phone.

The originally soft and warm scene was broken by Chen Tianzhen's question, and the scene became embarrassing for a while.

Ye Yurou walked over slowly, also sat on the sofa, and turned on her mobile phone to learn how to practice the tea ceremony.

After about ten minutes, Chen Tianzhen suddenly spoke: "How long have you known your eldest brother?"

Ye Yurou's hand holding the teacup paused again, her eyes were full of puzzlement, she stared at Chen Tianzhen and said, "Less than half a year, how did you know?"

Chen Tianzhen said flatly while playing with his mobile phone: "You can see with your eyes that you know him, and strangers' eyes are not like this." ”

"Is it possible to conclude based on just one gaze?" Ye Yurou frowned helplessly, this girl's acuity is too high.

"Yes, although I can see that you are not a bad person and are good to my big brother, but I don't know why, I just don't like you. Chen Tianzhen said.

Ye Yurou's brows increased a little more, and she said, "It's the first time we've met, right?"

Chen Tianzhen put down his mobile phone, with a little chill in his eyes, changed the normal state of the past, and said: "When you moved here, I saw you at my house, and if you want to say that you will meet, this is indeed the first time." ”
