In the early morning of this day, on the way, many inmates who got up early and studied hard found that the erudite and talented Guozi proctors represented by Luo Siye were actually walking out from the northwest corner with a panicked face, and their steps were so fast that it seemed as if there were ghosts chasing behind them.

The well-behaved prisoners hurriedly stood on the side of the road and saluted the teachers, but Luo Siye and the others only nodded slightly, and their steps did not stop at all, as if there would be an accident if they stopped.

Faced with this strange sight, those who had good things quietly followed their path to the past, and then found the old lecture hall with the door open. However, what made them even more strange than the opening of the door here was the evil star standing at the door of the lecture hall, staring at a pile of lanterns and candles on the ground with a complicated face.

That's Xu Heizi, the supervisor of the rope hall, his heart is even darker, and every prisoner will feel his buttocks tight when he sees him!

So, a few prisoners who came to see the excitement tiptoed back, and after that, they heard Xu Heizi's signature cold voice: "Lu Zhu, since you can memorize the nine chapters of the scriptures, then let me ask you, what does Yang Ma mean?

As soon as these words came out, several prisoners who thought Xu Heizi was questioning people looked at each other. One of them vaguely remembered where he had seen these two words, and for a moment his brow furrowed, pondering for a moment, racking his brains to recall the source. Soon, he waited for an answer.

"It seems that Xu Jiancheng has not read the nine chapters of the Sutra. ”

When he said this, Lu Saburo was full of spring breeze, and he was really proud. He was the only one who accused him of not learning and not knowing, and it was the first time he said that others didn't read! It wasn't until Zhang Shou's cough came from behind him that he quickly put away his thoughts of showing off.

"Let me explain it so simply, if there is a vast cube with a height of one foot each, and the top side is cut obliquely on the bottom, that is, there are two trenches, and then one of the trenches is cut obliquely along the bottom oblique line and the top corner, then one is a yang horse, and the other is a turtle. The size of the yang horse accounts for two-thirds of the entire trench, and the size of the turtle accounts for one-third of the entire trench. ”

Lu Sanlang looked at Xu Heizi's face was calm, but his eyes clearly revealed the word dazed, and he couldn't help but add triumphantly.

"My little gentleman's annotation on the nine chapters of arithmetic is that the yang horse is a quadrangular pyramid with a rectangular bottom, and the turtle is a triangular pyramid with a right triangle on both sides, and the size is the volume. As for rectangles and right-angled triangles, triangular pyramids and quadrangular pyramids, and what does volume mean, well, when I go back, my ancestor Ge will compile a terminology manual, otherwise you won't be able to figure it out. ”

Without waiting for Lu Saburo to explain again, Xu Heizi was already darkened and turned around and left. The few prisoners in the back who poked their heads out to see the excitement couldn't dodge, so they could only laugh and call out Xu Jiancheng, and then watched him walk away with trepidation.

As for Lu Sanlang, he grinned happily with his teeth bared and coldly slapped his head.

Don't forget what you said before, you have read the nine chapters of arithmetic, but for example, if I hadn't explained it carefully, you would have seen it in a fog! Show off in front of a layman, why don't you show off to Teacher Ge?"

The arrogance that had just risen was suddenly hit, and Lu Sanlang hurriedly hugged his head and said, "I cleaned Jiuzhang Hall all night last night, and I was so tired that my waist was about to break, can't I be proud for a while now?"

As soon as Zhang Shou wanted to say no, he saw a few prisoners who were peeping in the compartment, and immediately stopped the action of continuing to beat Lu Sanlang. He gently patted the dust off his body and walked towards the others. The glow of the morning sun shone obliquely on his face, so much so that he had to raise his left hand to block out the light slightly.

And several prisoners saw this handsome and handsome little Langjun walking towards him, and after hesitating for a moment, they finally came forward. One of them, the supervisor who finally remembered that the origin of Yang Ma and the turtle was indeed the Nine Chapters of Arithmetic, so he smiled and asked, "This little junior brother, just now Supervisor Xu asked about the Nine Chapters of Arithmetic?"

"What little junior brother, what kind of question!" Lu Sanlang, who was holding his head and feeling deeply aggrieved just now, rushed over at this time. He glared at the few inmates who didn't know what to do with it in annoyance, and then said angrily, "My little gentleman is the newly appointed Dr. Guozi, and the emperor's appointed Dr. Zhang! As for that Xu Heizi, he knows the nine-chapter arithmetic of a fart, what qualifications does he have to ask...... Ouch!"

Lu Sanlang, who didn't finish speaking, hit Zhang Shou again with a chestnut on his head.

And Zhang Shou, who bent two fingers to interrupt him, was stunned by the first few prison students, and he said with a smile: "That's right, I am the newly appointed Dr. Guozi, and I may be able to take classes in this Jiuzhang Hall in the future." ”

The newly appointed Dr. Kuniko ...... Oh my God, I just saw that people are young, and they actually call them little junior brothers!

A certain prisoner who had at least stumbled over the "Nine Chapters of Arithmetic" was so embarrassed that he was embarrassed, however, in the face of Zhang Shou's gentle smile, he only felt that the heart that had just almost jumped out of his throat seemed to be gradually falling back into his chest.

He took a deep breath, hurriedly bowed with a long bow, and then said cautiously: "I've seen Dr. Zhang, when we came over just now, I saw Luo Siye and a few doctors leaving in a hurry, it's hard to ......."

Lu Sanlang, who was holding his head, snorted coldly: "These guys were scared away by my left yang horse and right turtle hair. It's not as good as Xu Heizi, Xu Heizi at least doesn't understand and asks, those few don't know how to pretend to understand, and if they don't understand, they will run, no wonder they want to make Jiuzhangtang look like this, and they also picked up the imperial plaque of Emperor Taizu!"

The prisoner, who had just spoken, was taken aback. Not only him, but after several other people looked at each other, they knew that things might not be simple, but they still couldn't help but ask the reason.

Finding that Zhang Shou didn't stop him this time, Lu Sanlang immediately burst into tears, and explained how he sent Zhang Shou to take office last night, how he found that Jiuzhangtang was deserted, how to clean it, how he met Luo Siye and others to ask about the crime, and how he used Jiuzhang arithmetic to block people back...... It wasn't until the fat on his face shook that he stopped and gasped when the spittle was flying.

"All in all, my little gentleman is a disciple of Master Ge, and I am the grandson of Master Ge's apprentice. This arithmetic will be carried forward in the hands of our master and apprentice. ”

Lu Saburo's drama essence is really good and powerful......

Zhang Shou was too lazy to knock this guy anymore, seeing that Lu Sanlang fooled several prisoners so much that he couldn't move his eyes, and when he finally left, he was completely depressed, obviously because the reverence and fear of those division commanders all his time collapsed, he said lightly: "Those lanterns and candles on the ground have been collected." ”

After the excitement, Lu Sanlang was originally a little sleepy, but when he heard Zhang Shou's order and saw the candles all over the ground, he couldn't help but feel that these props were extremely easy to use when he was proud just now. However, when he saw Zhang Shou bowing his head and starting to remove the candles one by one, he could only resign himself to stepping forward to help.

"Little sir, is it useful for the two of us to make a fuss all night? If there is no one, there will be no momentum! If you want me to say, you should have left Zhang Chen and them together last night, and when I was cleaning, I also learned a lot of interesting things such as ciphertext with you, Mr. Xiao, and they can also gain something if they stay?"

"It's not that I said, Zhang Chen's guy seems to be powerful, but in fact he doesn't use it very much, his father usually doesn't care about him, as long as his father is afraid of hindering things, he will definitely not come today. As for Zhang Wu and Zhang Lu, it's the same. These guys, if they have milk, they are mothers, and they used to talk to Miss Zhu to see the momentum of Zhao Guogong's mansion......"

"If you don't say this, I know it. Zhang Shou yawned lazily, "Otherwise, why do you want to keep you? Don't look at so many people in Cuiyun, in the future, you will only be able to enter this Jiuzhang Hall and take the Eight Classics Arithmetic class, so even if you don't recommend yourself, only you are qualified to be the chief of fasting." ”

Without waiting for Lu Sanlang, who was overjoyed, to get carried away again, Zhang Shou said lightly: "As for whether it was useful for the two of us to do last night, you must know that Yingying is a person with a strong sense of action." ”

As soon as he finished speaking, he saw a fiery red figure not far away.

The familiar girl came to them in a hurry, and she didn't even have time to take a breath before she said bluntly: "The emperor came out of the palace and said that since Ah Shou is Dr. Guozi, Lu Sanlang and you are all prisoners, then the reward banquet mentioned before will not be placed in the palace, but directly placed in the Guozi Prison!"

At that moment, Zhang Shou couldn't help but smile at the stunned Lu Sanlang.

See, people who are more powerful than our teachers and students are here!
