These three people are demonic existences, Lu Yunzhou has been shocked by them countless times in the past few days, first of all, Zhang Cang, he finished all the primary school mathematics the next day, in order to balance their progress, Lu Yunzhou had to start teaching him Olympiad mathematics, Shi Wenqi is the oldest, and his IQ has almost developed, and now he has also learned all the knowledge of primary school mathematics, and he is reviewing, the most surprising thing is actually Lan Gongyuan.

Unlike Zhang Cang and Shi Wenqi, they have learned some arithmetic with Xunzi and Zou Yan, but Lan Gongyuan has no foundation, despite this, the young Lan Gongyuan still kept up with Shi Wenqi's progress, and also ate all the primary school mathematics within three days!

When he met this kind of student, Lu Yunzhou had a hunch that he would be able to retire soon.

Today, I can teach them junior high school mathematics, and by the way, chemistry, physics, and biology can also be put on the agenda......

After a stick of incense.

Zhang Cang first threw down the pen in his hand, raised his hands high, and cheered: "It's out!" How could such a simple problem as chickens and rabbits in the same cage stump the great mathematician Zhang Cang! ”

Lu Yunzhou couldn't help but cover his face, he deserved to be the guy who corrected "Nine Chapters of Arithmetic" in history, Zhang Cang's mathematical talent is really high, but this character is ...... It's too jumpy, isn't it......

Shi Wenqi also put down the pen in his hand refreshed, with a smile on his face, obviously finishing the topic.

For a bookworm like Shi Wenqi to strengthen obsessive-compulsive disorder, it is the happiest to complete one thing completely.

Lan Gongyuan was also writing and painting when they were writing the topic, and at this time she also put down her pen and stuck out her tongue cutely, obviously finishing her writing.

Lan Gongyuan smiled cutely: "Yuanyuan wants to help Brother Qi Yu do big things!" ”

Zhang Cang glanced at Lan Gongyuan stupidly, and also shouted: "Brother Qi Yu, do you have anything to ask Lord Zhang Cang for help, although he said, Lord Zhang Cang is still a little free now!" ”

Shi Wenqi said with interest: "Qi Yu, what is the matter?" It seems to be very interesting. ”

Lu Yunzhou announced with a smile: "We are going to make an invention together today!" ”

When the three of them heard that it was an invention, they immediately became concentrated.

"It's the invention of papermaking!" Lu Yunzhou announced the results with a smile.

Lu Yunzhou has long wanted to get the paper out, not to mention that the paper is easy to carry and the writing is clear, just going to the toilet - before the invention of paper, the toilet is used to wipe the chrysanthemum with a small bamboo piece called the toilet chip, and when it is done, it can be scraped on the chrysanthemum, and it can be reused......

Of course, Lu Yunzhou will not use the toilet to kill, and now every time he finishes a big event in the toilet, he will secretly use a dagger to cut a small piece of cloth inside his underwear to solve the problem.

Because Lu Yunzhou's underwear has often been missing a few pieces recently, Baoyue and the others have asked Lu Yunzhou many times, and they have been prevaricated by Lu Yunzhou every time.

It's disgusting...... Lu Yunzhou couldn't stand it for a long time, in order to avoid being disgusted to death one day, he must invent paper!

"Cai Lun, I'm sorry, I didn't mean to rob you of your invention...... Why don't you erect a monument of merit, even though you haven't been born yet...... But it will always be used...... Immeasurable Heavenly Venerable ......" Lu Yunzhou silently mourned for his conscience.

"Paper? What is it? Zhang Cang's eyes widened with a look of surprise.

Zhang Cang has always been a curious baby, and he always has great enthusiasm for new things.

Lu Yunzhou smiled mysteriously: "It's a good thing, okay, you clean up, I'll call Qi Xin, let's go out of the city and get the paper-making materials back!" ”

"Can you get out of town?" Zhang Cang cheered in surprise: "Great! ”

Lan Gongyuan also laughed happily.

Shi Wenqi shook his head and smiled on the side, after all, they are all children, they have been bored at home every day for the past few days, and they have long been bored!

After a stick of incense, Lu Yunzhou and Shi Wenqi rode on horses, Lan Gongyuan, Zhang Cang and Qi Xin sat in a carriage pulling goods, and Qi Xin drove the carriage to the outside of the city.

Originally, Qi Mansion also had a foal that Zhang Cang could ride, but this little ghost saw that Miss Lan Gongyuan was also sitting in the car, so he followed him to ride the carriage with a dead face.

On the way, he actually met Zhongsun Xuanhua, Ma Chengjia and Min Jianzhang, and Lu Yunzhou immediately planned to arrest Zhuangding: "Senior Brother Zhongsun, Senior Brother Ma, Senior Brother Min!" ”

"Senior Brother Qi, what are you planning to do?"

The three of them greeted each other happily, not knowing that they had been remembered by Lu Yunzhou.

Lu Yunzhou said with a smile: "We are going to Shenchi, do the three senior brothers want to be together?" ”

The three of them were bored discussing where to have fun, and when they heard this, they readily agreed.

Zhongsun Xuanhua said happily: "You can't sit in this carriage, just drop by, go to my house to lead a few horses first!" ”

"Okay!" Lu Yunzhou snickered in his heart.

The group led four more horses in Zhongsun Mansion, and Zhang Cang was also unhappy to ride the foal, because he was mercilessly ridiculed by Zhongsun Xuanhua and the others for not being able to ride a horse, and he also sissy rode in a carriage with the girl.

"You ordinary people, how can you understand Lord Zhang Cang's great ambitions, hum!" Zhang Cang unhappily shook the horsewhip in the air, and his eyes glanced at the beautiful and lovely Lan Gongyuan who was sitting in the carriage.

The group went to the south of the city, and after leaving the city gate in the southeast of the city, the Ning Gate, they could let their horses run as much as they wanted.

Outside the city is the grassland of a flat river, the left side of the crowd is the vast Linzi mother river - Zishui, in front of the peaks and peaks, the magnificent and majestic Niushan mountains, the right side of the grassland is exhausted, faintly visible sparkling, there is Shenchi.

Ma Chengjia, a good deed, proposed: "Let's race horses and see who gets to Shenchi first!" ”

Min Jianzhang is also a combatant, and immediately agreed when he heard this, "No problem! Last place, please drink! ”

Zhongsun Xuanhua laughed and said, "Which of you will invite Uncle Ben to drink!" ”

Lu Yunzhou turned his head and instructed Qi Xin: "Xiaoxin, you take Yuanyuan to drive well, pay attention to safety, don't worry, just go to Shenchi to find us." ”

Qi Xin nodded and replied, "I know, young master!" ”

Lan Gongyuan said obediently: "Brother Qi Yu don't worry about Yuanyuan, Yuanyuan and Brother Xiaoxin will soon go to you!" ”

Zhang Cang shouted: "You bully people, my horse is the youngest, I don't participate in the race!" I still have to stay to protect Sister Yuanyuan! ”

"Hahahaha!"

"Little ghost, you stay!"

Everyone suddenly burst into laughter, and Zhang Cang sulked with his hands on his chest.

Lu Yunzhou couldn't help but laugh and said: "Then Zhang Cang is with Yuanyuan, let's go!" ”

"Let's go!" Ma Chengjia flicked his horsewhip first, and rushed out like an arrow.

Several others hurriedly followed.

Shi Wenqi smiled bitterly and patted the horse to keep up, he was just a powerless scholar under the chicken, barely able to ride a horse, how could he compare with these agile swordsmen.

"I'm sure I'm going to drink, no suspense." Shi Wenqi nervously grabbed the reins of the horse and lamented.

Lu Yunzhou inherited Qi Yu's physical memory in this life, and his equestrian skills were not bad, he didn't compete for the lead, but just followed closely.

Horse shoes had not yet been invented during the Warring States period, but saddle sheaths had already appeared, so the feeling of riding a horse was barely acceptable.

Lu Yunzhou did intend to invent the horse pedal in this era, but it is not now, good steel should be used on the blade, and the appearance of the horse pedal should also be in a key battle.

Shenchi is the source of the water, located in the south of Jixia School Palace, the southwest of Linzi City, the lake is wide, the smoke waves are vast, the sky is bright up and down, a blue expanse, it is a bright pearl inlaid in the grassland on the outskirts of Linzi City.

Lu Yunzhou followed closely after Zhongsun Xuanhua, who was in the lead, and galloped to the edge of Shen Chi before stopping, and Ma Chengjia and Min Jianzhang arrived one after another behind him.

Blowing the breeze from the lake, looking at the surrounding scenery, Lu Yunzhou suddenly felt relaxed and happy.

After a while, Shi Wenqi was late, and looked at the few people waiting by the lake with a wry smile.

"I'll drink!" Shi Wenqi didn't wait for them to run, so he honestly admitted it himself.

"Haha, Senior Brother is too kind!" Zhongsun Xuanhua squeezed his eyebrows and smiled: "Don't worry, we won't bully people who haven't practiced martial arts, this trip can be regarded as Senior Brother Min's loss." ”

Min Jianzhang admitted: "No problem, you can drink wherever you want!" ”

Shi Wenqi breathed a sigh of relief when he heard this, and suddenly felt that he liked these people a little, and hurriedly smiled: "I did lose, then I will be responsible for the snacks!" ”

"Okay, that's it!" Zhongsun Xuanhua waved his hand, extremely arrogant.

Lu Yunzhou smiled: "You still don't know what we're here for, right?" ”

"For what?" Ma Chengjia said stunned.

Lu Yunzhou gently clamped his legs, rode his horse to a vast bamboo forest on the west side of Shenchi, and laughed: "Come with me!" ”

Lu Yunzhou snickered maliciously, the strong men were all arrested, so they were naturally working......

Half an hour later......

In the middle of a vast bamboo forest.

A towering giant bamboo fell down with a "squeak", and the bamboo leaves fell like rain, and the giant bamboo bent several nearby bamboos before slamming into the ground.

There are already three giant bamboos stacked on the ground, and this one is the fourth......

Ma Chengjia carried a saw and a firewood knife, panting and said: "Qi Yu, after a long time, it turns out that you arrested us to work, you ...... Enough, I remember you! ”

Lu Yunzhou was also sweating profusely, he didn't know what it meant to be embarrassed, and said with a smile: "Don't worry, when the paper is made, you will know how great what we are doing today!" ”

Zhongsun Xuanhua said angrily: "Qi Yu, let's say okay, the paper you said has been made, and I want to give each of us a car!" ”

Lu Yunzhou stretched out three fingers, made an oath, and said with a smile: "No jokes!" ”

Shi Wenqi blushed and gasped: "These should be able to fill that car, let's just divide it into sections." ”

"Okay", Lu Yunzhou walked towards the giant bamboo on the ground with a saw, and the others also surrounded him weakly.

"Ahh

At this moment, a terrible scream came from a distance, instantly echoing throughout the bamboo forest.

"What's going on?" Everyone was shocked and moved, and looked in the direction where the screams came from, but they saw that they were covered by huge bamboos, and they couldn't see far at all.

But not long after hearing that scream, a second terrible scream came again--

"Ahh
