"Boss Chen!"

Mei Hanyan exclaimed, on the side, Li Siyi looked sluggish, and after about two seconds, Li Siyi poked Mei Hanyan's hand. Pen, fun, and www.biquge.info

"Senior sister... Your voice... It's too big. ”

"I'm loud.... Oh, I'm sorry...."

Mei Hanyan was a little stunned, how could this guy appear here?

She was a little confused, but she didn't know that at this moment, the students sitting in the classroom were even more surprised and confused because of Mei Hanyan's words before.

"Senior Sister Mei knows this new lecturer?"

"I don't know, this teacher has never seen it. ”

"Could it be Senior Sister Mei's..... Boyfriend?"

"it, no!"

"What nonsense are you guys talking about, didn't you hear what Senior Sister Mei said before?"

"Yes, it seems to call him Boss Chen?"

"Boss, so young is the boss?"

"I don't know, maybe it's a small business?"

"Tsk, what's the ...... then?"

The students were discussing, and Li Siyi whispered to Mei Hanyan: "Senior Sister Mei, you... Do you know this teacher?".

"Recognize.... Of course I know ....."

Mei Hanyan took a deep breath, then looked at Li Siyi, but said with a smile: "You are gambling with you.... I'm done. ”

"Huh?"

Li Siyi was amazed and puzzled: "Senior Sister Mei, you call him Boss Chen, is he the boss there? Is it the kind of business run by Xiaoben? ”

"Hmm.... Small business.... Small business ....."

Mei Hanyan smiled bitterly, a little unsure of what to say, the other party is a small business? It's really not big enough.....

You can't say that.....

Mei Hanyan shook her head, looked at Chen Yuan behind the podium, and was a little speechless for a moment.

This guy can be regarded as the person who really does business in the heavens and the earth and the whole earth......

Mei Hanyan knew what a strange office it was, including the force that this boss had, it didn't look like a human being.

"Hello students. ”

Chen Yuan spoke, his voice was not loud, but it was clearly transmitted to everyone's ears.

"Huh?"

Li Siyi looked at Chen Yuan strangely, and then whispered to Mei Hanyan: "This.... He spoke in a voice as if he were speaking directly in my ear!"

"Hmm...."

Mei Hanyan responded, a little absent-minded, she was more concerned about why this Boss Chen was Professor Tian's substitute lecturer?

"Professor Tian has something to do, I have to take a break for a while, this time may be longer, well, in the next period of time, I will come to class on his behalf. ”

Chen Yuan sorted out the books on the podium: "Today, we are going to talk about ......"

"Teacher!"

Li Siyi raised her hand, Mei Hanyan looked at her in surprise, Li Siyi blinked slyly, and whispered, "Senior sister, don't blame me." ”

"Poof. ”

Mei Hanyan shook her head with a smile, and secretly said that although she didn't know why Boss Chen appeared here, he showed up, indicating that he must have made sufficient preparations.

Thinking of the other party's unpredictable methods last time, the doubts in Mei Hanyan's heart couldn't help but get stronger, that elixir really only has an expiration date of one month?

Clenched her fists, Mei Hanyan looked at Chen Yuan in the audience, and the curiosity in her heart became even stronger.

"Well, Li Siyi..... What's wrong with you?"

Li Siyi rolled her eyes, pursed her lips, and said, "Teacher, students want to ask, what happened in history in 105 AD?"

There was a hint of provocation in her words, which is also a situation that many substitute teachers encounter, college is not as good as high school, and it is difficult to convince students if they do not have excellent knowledge.

Chen Yuan raised his head and looked at her, Li Siyi was a little nervous, but her two smart eyes still looked at Chen Yuan without blinking.

I want to see why you can make Senior Sister Mei so respectful!

The corners of Li Siyi's mouth hooked, 105 AD was the famous Cai Lun papermaking incident, on the basis of the original, Cai Lun improved and promoted papermaking.

If you can't answer something so simple, hum....

Thinking so, Chen Yuan looked a little indifferent, and said softly: "In 105 AD, the year of the Chinese lunar calendar, the year of the snake of the zodiac, Emperor He died, and Emperor Yan ascended the throne. It belongs to the seventeenth year of Yongyuan of the Han Dynasty and the first year of Yuanxing. ”

"In the seventeenth year of Yongyuan, that is, in the spring of 105 A.D., the palace of the king of Goguryi restored Liaodong and plundered six counties. In September, Geng Kui, the Taishou of Liaodong, defeated the Gaoguryi army and beheaded its commander. ”

"In the seventeenth year of Yongyuan, that is, in the year 105 A.D. In the summer of April, the amnesty was granted to the world and the Yuan Yuanxing was changed. ”

In December of the first year of Yuanxing, Emperor Liu Zhao died, and the young son Liu Long was the emperor, and Liu Long was born only for more than 100 days. Respect Empress Deng as the queen mother, the queen mother is in the dynasty to weigh the system. ”

In the first year of Yuanxing in the Eastern Han Dynasty, Cai Lun reformed and promoted papermaking technology on the basis of the former artificial paper. ”

"Before the advent of Cai Lun papermaking, in China, the Shang Dynasty used oracle bones, the Western Zhou Dynasty used bronze vessels, and the Spring and Autumn Period used bamboo tubes, wooden scrolls, and silk as memorization materials. In the Han Dynasty, agriculture was developed, the economy was prosperous, the national strength was strong, and cultural undertakings flourished. Bulky bamboo tubes and expensive silk could not meet people's needs, and the search for new writing materials became the trend of the times, so papermaking came into being. ”

Chen Yuan paused and continued: "The Book of the Later Han Dynasty and the Biography of Cai Lun records that before Cai Lun made paper, the paper on which he wrote the notes was actually silk and silk, that is, silk, and Cai Lun used bark, hemp, rags, and fishing nets to produce plant fiber paper, a real sense of paper, after a series of processes such as frustration, pounding, copying, and baking. ”

In 105 AD, Cai Lun presented paper to Emperor He of the Han Dynasty and was praised by Emperor He. Papermaking was then widely known to the world, and the paper made by Cai Lun was called "Cai Hou paper". The year 105 is generally considered to be the year of the invention of papermaking. ”

Chen Yuan looked at Li Siyi, Li Siyi's mouth opened slightly, she knew what the other party said, but there was no way to be so accurate, and she memorized it word for word.

"What's the problem? If you don't, sit down, and when you go back, take a hard look at the historical years, which are all in the books. ”

Chen Yuan stopped looking at her, Li Siyi's face was slightly flushed, and she spoke again: "Teacher, I still have questions." ”

"Speak. ”

Li Siyi's little face was puffed up, she thought about it, and said with a smile: "Teacher, when did Wang Mang add Jiuxi?"

Chen Yuan's face was expressionless: "May of the fifth year of AD." ”

Li Siyi: "......."

"Teacher, when was the Treaty of Verdun established?"

"August 843 A.D. ”

"Teacher, what happened in 215 BC?"

"The Battle of Syracuse broke out, the Roman Empire sent a powerful navy, led by the Roman general Marcellas, to attack the ancient Greek city of Syracuse on warships, and the Macedonian War broke out from 215 to 205 BC. ”

"When was the Dracula Code enacted?"

"621 BC. ”

"Where are the Judicial Archons, and in what era?"

"One of the nine consuls of Athens, he enjoyed judicial and legislative power in the early days of the Athenian state. Incidentally, the Codex of Dracula was one of them, and his name was Dracula. ”

"When was the completion of the Altar of Zeus?"

"2nd century BC. ”

Li Siyi's face was a little flushed, she took a deep breath, and then spoke to Chen Yuan.

"Hello teacher. ”

"Well, sit. ”

Chen Yuan nodded expressionlessly, and then asked, "Which other classmate has a problem?" You can raise it, and we will solve these things first." ”

No one spoke.

Chen Yuan nodded: "Then go to class." ”

Li Siyi sat down and whispered to Mei Hanyan: "Is he a monster? I said a lot of it casually, I don't even know it, he..."

"He's a monster. ”

Mei Hanyan smiled, then looked at Chen Yuan behind the podium with interest, and muttered:

"Boss Chen.... What are you thinking?"
