The Great Song Dynasty: You were put in charge of teaching, and you produced a whole bunch of prime

three days later.

The winds in Hangzhou have shifted again, and this time they've become extremely strange.

In the backyard of the Lin family mansion, several members of the Lin family's collateral branches were sitting around a table, scratching their heads in frustration.

"This isn't right!" A young scholar slammed down his brush, pointing to the draft paper in front of him. "According to the formulas in this book, if this dike is to be three zhang high, the base would have to be ten zhang wide! This isn't building a dike, it's filling in a lake!"

"Exactly! And then there's the salt tax problem." Another scholar, equally distraught, exclaimed, "I've calculated it all, and here's a deficit of 50,000 strings of cash out of thin air! If we collect taxes this way, the imperial court will go bankrupt!"

The head of the Lin family happened to be walking over for an inspection. Upon hearing this, his face darkened: "What's all the noise about! Just memorize what's written in the book! Those were questions set by Su Shi; how could he possibly get them wrong?"

"But Uncle, this really doesn't make sense!" The young scholar was almost in tears. "The numbers here are completely contradictory. If we write this on the exam paper, the examiner will definitely think we're fools!"

The Lin family head's heart skipped a beat. Although he didn't understand mathematics, he knew that this matter was strange.

Just then, the Lin family's steward stumbled in and scrambled to his feet, landing at the feet of the Lin family head.

"Master! Something terrible has happened!"

"What kind of behavior is this, all flustered and disrespectful! Speak!" the Lin family head scolded.

"Outside...outside is in complete chaos!" The butler gasped for breath. "That young master from the Zhang family in the east of the city, who failed the imperial examinations three times, was doing practice questions using a pirated book sold in our bookstore. He discovered that all the water conservancy blueprints inside were reversed! He consulted a knowledgeable old bricklayer, who said that if the canals were built according to those blueprints, the water would flow backwards into the city!"

The Lin family head's mind went blank, and he almost lost his balance.

"Now, the eldest son of the Zhang family has led hundreds of scholars to smash up our family's bookstore! They're accusing us of selling counterfeit books, deliberately harming scholars in Jiangnan, and trying to ruin their careers!"

"What?!" The Lin family head's vision went black.

He finally realized what had happened. Jiang Lin! It was definitely that bastard Jiang Lin who did it!

He deliberately released books containing errors and omissions for them to pirate, using them to spread this erroneous knowledge. Now, all the wealthy young men in Jiangnan who bought pirated books have been led astray!

"Quickly! Send someone to shut down the bookstore! Burn all those books!" the Lin family head roared in a fit of rage.

But it was too late.

The entire city of Hangzhou is in complete uproar.

Countless scholars, realizing they had been scammed, angrily flocked to the bookstores that sold pirated books, smashing their signs and demanding refunds.

At the same time, a queue ten times longer than before formed at the entrance of Jingshi Academy.

Qian Duoduo stood on the high platform, holding a thin piece of paper in her hand, and shouted loudly, "Look carefully! This is an 'errata sheet' exclusively printed by our academy! Only by holding this errata sheet and comparing it with the anti-counterfeiting watermark on the genuine book can you see the truly correct data!"

"I'll buy it! I'll offer twenty strings of cash!"

"Give me a copy! I'll pay thirty strings of cash! Just let me take a look at that errata sheet!"

Those scions of noble families who were mocking the academy for its high prices yesterday are now red-eyed, waving their silver notes and desperately pushing forward.

They were scared. Really scared.

The imperial examination was a lifelong endeavor for them; if they entered the examination hall with flawed formulas in their minds, their entire lives would be ruined.

Jiang Lin stood by the second-floor window, looking down at the group of crazed people, and coldly shook his head.

"If only you had known this would happen, you wouldn't have done it in the first place." Jiang Lin turned to Su Shi behind him. "Zizhan, have any people been causing trouble at the government office these past few days?"

Su Shi, dressed in casual clothes, was happily drinking a bowl of chilled mung bean soup.

"What do you mean, 'no'?" Su Shi wiped his mouth and snorted coldly. "Those old fellows from the Zhang and Li families came to the yamen yesterday, saying that the exam questions I set were too obscure and were deliberately making things difficult for scholars. They demanded that I abolish the new regulations and revert to poetry and prose."

"What did you reply?" Jiang Lin asked with great interest.

Su Shi slammed down his bowl and, mimicking Jiang Lin's usual tone, said arrogantly, "I smashed the gavel. I pointed at their noses and yelled: 'You old bastards, eating the Song Dynasty's salary, you don't even know how much grain an acre of land can produce, what right do you have to talk to me about the ways of the sages? You're not convinced? If you're not convinced, then don't let your little brats take the exam!'"

Jiang Lin laughed heartily and patted Su Shi on the shoulder: "Well done. To deal with these people, you have to be even tougher than them. If you back down, they'll take advantage of you."

"However, Headmaster," Su Shi frowned with some concern, "the rules for the exam questions have changed, and the collection of past exam papers is now available. But these scions of aristocratic families simply can't understand those practical questions. Even if they have the correct errata sheets, they haven't actually used them, so they'll just write nonsense in the exam hall. If too few people are admitted in this provincial examination, I'm afraid there will be criticism from the imperial court."

Jiang Lin's smile faded, and his eyes became deep and thoughtful.

"You're right. If that's the case, Cai Jing will definitely use it as an excuse to make trouble." Jiang Lin walked to the table, poured a cup of tea, and said, "So, we need to give them a 'chance'."

"An opportunity?" Su Shi was stunned.

Jiang Lin's lips curled into a dangerous smile: "Duo Duo!"

Qian Duoduo, who was outside the door, immediately rolled in like a ball: "Headmaster! What are your orders!"

"Go outside and post a new notice," Jiang Lin said slowly. "Say that, in order to alleviate the difficulties faced by scholars in Jiangnan in learning practical skills, Jingshi Academy is now offering a 'Pre-Exam Intensive Class.' It will be taught by Shen Kuo, the great master of physics in our Song Dynasty, and will guarantee that you will learn it."

Qian Duoduo's eyes lit up; she immediately sensed the scent of money: "Then what about the tuition..."

"One hundred strings of cash per person. No bargaining." Jiang Lin casually uttered a number.

Su Shi gasped in shock. One hundred strings of cash! This was practically robbery!

Seeing Su Shi's shocked expression, Jiang Lin said calmly, "Since they want to be officials, they'll have to pay a 'stupidity tax.' I want them to know that in this era, knowledge is the most valuable thing."
