And the thorn in the story is the famous thorn, because in the Eastern Han Dynasty, the name of the thorn was replaced by the thorn. There are even people who add official positions and age to the thorns, etc., for the purpose of visiting the upper peak, called the Jue Li Thorn, this kind of field business card has a special writing format, to write all the content in the center of the thorn into a line can not be split, so it is also called a long thorn.

The reason why it was changed to a thorn was that Liu Xi of the Han Dynasty made a note in the "Interpretation of the Name": the book is called a thorn, and the book is also a bamboo slip with a pen. It means that this thing is engraved on the bamboo slip with a knife and pen, as a sign of the identity and name of the visitor. This son uses high-quality thick paper, and writes in lacquer.

No way, but all the noble families, the name thorns used are in this format, I naturally follow the customs, anyway, when I was working outside in the later generations, I was obviously just an intern salesman, but I was the company's business manager, which is enough to see how foolish the business cards of later generations are.

But fortunately, the famous thorns of this era do not have that pompous style, if you are blind, you will definitely provoke people's ridicule.

Half an hour later, Li Yuanfang appeared, followed by a middle-aged man in his early thirties, very tall, with three long beards, who looked very fairy-like, but now this guy seems to be a little angry, his steps are like flying, even a tall man like Li Yuanfang has to hurry up to lead the front

"He is Yuan Tiangang." Sister Qingxia whispered to me after seeing the faces of the people who came. Ben Gongzi couldn't help but be secretly happy in his heart, it seems that the exercises that Ben Gongzi did were really seductive.

"Could this be the Duke of Qi who is famous in the Eastern Capital?" As soon as Ben Gongzi stepped down the steps, Yuan Tiangang had already rushed to the bottom of the steps, and after looking at me twice, he seemed to be a little surprised and said, "I didn't expect Qi Guogong to be so young." It seems that the words of the hero are very suitable for evaluating the national prince. ”

Sure enough, it is worthy of being a god, as soon as Fang met him, a bunch of sycophants were patted over, even a reserved and upright gentleman like Ben Gongzi was photographed with a smile on his face and a happy face. "Don't dare to be, I've heard the name of Yuan Yanguan for a long time, and when I see it today, it is really immortal, and it is natural, and it is beyond the reach of ordinary people like Wuji."

…… Well, as the so-called chess opponent will meet a good talent, Yuan Tiangang is a good comrade, but also a good opponent, not only to praise others, but also to take the opportunity to elevate himself, of course, this son is not good at his generation, really, it has been a long time since I have been so intriguing with others while patting each other's ass.

In the end, Ben Gongzi and Yuan Tiangang, who were foaming at the corners of their mouths, closed their voices together, looked at each other and laughed, seeing that Sister Qingxia and Li Yuanfang looked inexplicable. "Little lady, what's wrong with him, childe?" Sister Qingxia poked my sister with her hand and asked quietly.

"This should be what my brother once said about sympathy, two thick-skinned guys." My sister's answer made my son almost fall down the steps, and glared at the little girl stupidly, and then showed an amiable smile to Yuan Tiangang. "Brother Tiangang, please."

"Don't dare, please assist the son." Yuan Tiangang took a half step back, not arrogant or humble.

"Well, if Brother Tiangang can afford to look down on the little brother, please call the little brother Wuji." Ben Gongzi grinned and said with a forced smile, forget it, forgive this guy for the time being, just treat him as a gaffe.

"That day, Gang Ke is better to be respectful than to obey his fate, Wuji Gongzi, please." Yuan Tiangang is really good

Entering the hall, after the guests sat down from the host, Yuan Tiangang, who poured a large sip of ginger tea, couldn't wait to ask me about the questions on the test paper that my son had just made.

Even the girl who has studied mathematics and geometry with me for almost a year can't figure out the above questions. And Yuan Tiangang, who had never learned Arabic numerals, just learned the numbers from Li Yuanfang, and then through his own deduction, he got the answer.

This kind of ability is definitely beyond the reach of Ben Gongzi, but Yuan Tiangang came over, this guy actually asked Ben Gongzi to teach these mathematical symbols and how to use these symbols to calculate.

For this son, it is simply three fingers to pull a snail, and his hands can be caught. Just took the test paper and explained it to this guy a little, Yuan Tiangang suddenly felt like a treasure, and his eyebrows were beating there. It took a long time for this guy to come back to his senses and solemnly thank his son.

"Brother Tiangang, why should you be like this, the younger brother is lazy and learns this, but because he has some interest, but if these things can be passed down by Brother Tiangang, it will be a great thing for the benefit of the country and the people." I waved my hand and said very earnestly. When these words came out, Li Yuanfang, Sister Qingxia and my sister all looked adoring.

But Yuan Tiangang looked deeply shocked, looked at the test questions in his hand, and then looked at the man standing in front of the desk, with a calm and calm face, generous and compassionate, willing to scatter the seeds of science all over the land of China, and only willing to cultivate and not want to leave a name.

This guy stood in a daze for almost a pillar of incense, and just when Ben Gongzi's upright gentleman's expression was about to stiffen and couldn't keep it anymore, Yuan Tiangang finally made a decision, and after putting the test question on the desk, he knelt down and slammed it to the ground. "Mowgli son, can actually create a way of arithmetic innovation from the ancient classics, although Tiangang is very envious, but he is not a person without virtue, if Mowgli is willing, Yuan Tiangang is willing to worship Gongzi as a teacher."

"What?" This boy made this guy so frightened that he took three steps back, and his throat almost squeezed out the sound of chickens, and even Sister Qingxia, a beautiful girl who usually looks so calm and calm, was frightened. "This, this, this...... How is this possible? ”

"That's right, I'm much younger than you, brother, it's really inappropriate for you to worship me as a teacher." The corners of my son's forehead are sweating, which one is this guy playing? Could it be that this guy has an old relationship with Chai Shao, and deliberately helped that guy come over to scare this son?

Yuan Tiangang shook his head with a straight face: "This is inappropriate, Confucius said: If you are a threesome, you must have my teacher." Childe's talent, Tiangang is far from it, just refers to Childe adopted this kind of Arabic numerals, and then created these novel and unique, but easy-to-understand mathematical symbols, so that mathematics, no longer as in the past is too abstract, only this one achievement, enough to go down in history, is a model for people in our generation of arithmetic. ”

"It is Tiangang's wish to be able to enter the door wall of the son, to pass on such skills, if the son does not give up and accepts Tiangang as a disciple, Tiangang is grateful......" Yuan Tiangang said that after the most sorrow, tears flashed in his eyes, by the way, a big man in his early thirties, actually began to play the sad card.

At this time, Sister Qingxia gently tugged at my sleeve, bowed slightly at me, kept blinking her eyes, and whispered a word. "The ratio of arithmetic to ......" depends on, or Sister Qingxia is sensible, which reminded me at once.

"Brother Tiangang, in this way, if you are willing, how about you and I intersect with each other and learn from each other?" I walked past the case and wanted to help Yuan Tiangang up, but this guy was so hard-hearted that he couldn't hold it up. I was dizzy, so I could only sit in front of him, very earnestly. "In fact, what the younger brother hopes more is that the scholarship of arithmetic people like you and me can be recorded in pen and ink and passed on to future generations."

Ben Gongzi fooled Yuan Tiangang very earnestly, telling him that if he was willing to talk to Ben Gongzi's peers, Ben Gongzi's lifelong learning could teach him, but there was one thing, he had to work with me to create a complete version of "Principles of Mathematics" and a complete version of "Principles of Geometry".

And I hope that in three days, this guy can help and become a referee, I believe that he, as an old god and a master of mathematics, will be able to do well in this referee's profession.

Yuan Tiangang promised to help in three days, but he would never agree to my request, thinking that I had the ability and ability, so it was absolutely appropriate to be his teacher.

In the end, the son who persuaded the spit stars to be dry was angry. "I said, what are you going to do to say yes? I've told you, this is what this son learned from ancient books, I can learn, of course you can also learn, what to worship. ”

"There is a precedence in hearing the Tao, and there is also a precedence in getting started, since the childe's talent is far higher than mine, if the son is unwilling to accept me as an apprentice, please also ask you to accept the apprentice on behalf of the teacher, Yuan Tiangang is willing to serve the son as a senior brother."

I Khan, Arabia, Shibi Khan, Huangguoshu Waterfall Khan. This guy is really a cow, and he can't look back no matter how he pulls it, so his son waved his hand frustratedly: "Let's go, it's up to you, anyway, Brother Tiangang, you can do whatever you like." ”

"Thank you, senior brother, Tiangang has seen senior brother." Yuan Tiangang's face suddenly showed joy, and after bowing to his son, he got up with Shi Shiran.

Well, although Ben Gongzi put on an unhappy and helpless expression, in fact, I still like it very much in my heart, after all, I have the soul of a traverser, and I also have a restless and restless heart, I like to show off, let such an old god stick be my disciple, if this is recorded in the history books, then Ben Gongzi will definitely be able to wake up from the ancient tomb with a smile.

Countless people in later generations want to be famous, but the question is, what else is easier than being famous as a good traverser? For example, this son is such a low-key lewdness, if he doesn't look for trouble, he will find me for everything. Throwing out a third-grade junior high school test question, you fooled a famous god stick in history and fell down under my door? Well? …… The disciple is the disciple, and the junior disciple should squat by the door. This is the peerless demeanor of an excellent time-traveler that blinds countless historical figures.

Bidding farewell to this teacher and brother at the gate of the house, this son stood with his hands in his hands, and he was very emotional. "It's just such a small test paper, and it actually caused such a big incident. Alas...... It seems that in the future, you should keep a low profile, and try to be as low-key as possible. ”
