Although Merton's five-day vacation was very difficult, when the vacation ended, Merton was still reluctant for a while, and it seemed that the days of the young master who were waiting for death were still far away.

When Morton came to Guozijian again, he immediately felt the strange eyes of the other students, which made Morton confused.

Zu Mingjun circled around Morton a few times, as if he had just met him, he had just been dragged back to Fanyang's hometown by the elders of the ancestral family, and he worshipped his ancestors in a big way, and told Zu Chongzhi that there was another talent in the descendants of the ancestral family, and he had just been released back.

"There's something to talk about!" Merton was annoyed and embarrassed.

"I didn't expect you to have such peerless painting skills! It's only been a few days since I left Chang'an City, and you've made a big deal again" Zu Chongzhi smacked his tongue, when he came forward to compare arithmetic with Merton, he was already a sideliner, but he didn't expect that Merton was hiding so deeply, and there was still a trick that didn't come out.

"What is this? This young master will have a lot of skills! Merton said with a stinky fart.

"It is worthy of the decathlon Mo family." Zu Mingjun gave a thumbs up, but his expression didn't mean to appreciate.

At the beginning, the Mo family was actually derogatory in Chang'an City, saying that Murton was just a yellow-haired boy of the Mo family, and now when Morton has repeatedly created miracles, people no longer have a derogatory meaning when they talk about the Mo family.

"you!"

The class where the two of them will come to the class if they fight and make trouble, and this class should be the class of Shen Hongcai, a doctor of arithmetic.

During Merton's vacation, although Merton thought that he had a hard time, there was one person who was even more difficult than him, that is, Shen Hongcai, a doctor of arithmetic.

In the entire Tang Dynasty, Shen Hongcai thinks that there are very few people who can surpass him in arithmetic, of course, with the recent addition of a demonic Mo family, there may also be an ancestor in the future.

But since Kong Huisuo took over the arithmetic notes from Zu Mingjun, everything has been messed up.

Kong Huisuo is like taking medicine, and the level of arithmetic has increased in a straight line, which naturally attracts the attention of other prisoners, and arithmetic is now an important subject related to the graduation of Guozi prisoners, and now all the Guozi prisoners who are poor in arithmetic are not calm.

After learning that Merton did not care about the spread of his new arithmetic, all the Guozi prisoners in the Bingsha where Merton was located overnight had a copy of the notes of the ancestor Mingjun.

Although there is no Merton personally taught, don't underestimate the prisoners who can enter the Guozijian, except for those who go through the back door like Cheng Chumo, the others are comparable to the students of the highest universities in later generations.

They themselves were extremely intelligent, and they had good arithmetic skills, not to mention that Arabic numerals and intensified multiplication and division of squares were not such rare problems, so overnight, the arithmetic level of the entire Guozi Prison students of Bingsha improved as a whole.

It stands to reason that students should be happy about their own good grades, but what if a student's grades are so good that they even surpass their teachers?

There are some questions that Shen Hongcai still needs to think about for a long time and calculate for a long time to get the correct answer, but Bingshe's students opened their mouths to answer them instantly.

And there is not one such student, but a class, given time, I am afraid that Shen Hongcai, the master of the whole class, will be the worst, which makes Shen Hongcai embarrassed.

Fortunately, it is not difficult to find out the reason for the increase in students' grades, and when Shen Hongcai looked at the Arabic numerals and various mathematical formulas in his hand, he couldn't help himself for a long time.

"What a decathlon Mo family, what a Tianzhu number!" Shen Hongcai's mind floated and he was deeply impressed.

At the entrance of the classroom,

Shen Hongcai hesitated, took a deep breath, pushed the door in, today he will make a decision, a decision that will affect his life.

Shen Hongcai stood in front of the brand-new blackboard, looking at the last row of Mo Dun couldn't help but feel a little abrupt, unconsciously, Guozijian had deeply left traces of the Mo family, the blackboard was also, the chalk was too, and the thing he was about to do was also.

"Hello Master!" All the students stood up and said hello.

"You may be seated!" Shen Hongcai was slightly relieved in his heart, even if these students surpassed him in calculations, they still respected their teachers so much.

Shen Hongcai took a deep breath and reflexively wrote on the blackboard from zero to nine, nine Tianzhu numbers, and it was written from left to right.

Today, he not only formally accepted the Tianzhu number, but also accepted the calculation method of the Tianzhu number, from left to right, which is a subversion of the existing writing rules from ancient times to the present.

When Shen Hongcai really wrote down these ten numbers, Shen Hongcai deeply realized the writing rules that Morton said, which has nothing to do with dignity and humility, just habits.

In the past, when Shen Hongcai used the blackboard, he wrote from top to bottom, from right to left, and every time he wrote, he would pinch his wrist to write, and he was tired.

Not only is it unsightly, but sometimes the written words are blurred, which is very inconvenient, and writing from left to right does not have these problems at all.

"Master is wise!" All the students in Bingsha understood the meaning of the ten numbers written by the Master, and they couldn't help but cheer.

Morton was also stunned to look at Shen Hongcai, who seemed a little energetic in front of the blackboard, and couldn't help but be in awe, this is a real scholar, the most important thing in his life is learning, and he can break through all the obstacles in the world in order to learn.

After Shen Hongcai really did this, his heart suddenly became clear, of course he knew that doing so was likely to ruin his future in Guozijian, but he still had no regrets.

"The old man is probably the last person in this class to come into contact with these numbers, maybe you will think that the old man is an old stubborn! But today, my old stubbornness is also conquered by these beautiful figures, and the old man is here to take all the students here, and thank Merton for teaching such a secret skill of arithmetic. After Shen Hongcai finished speaking, he bowed deeply to Merton.

Mo Dun was startled, and hurriedly got up and saluted: "Master praises it, these numbers are not the secret skills of the Mo family, but the Tianzhu numbers, and the Mo family can't take the credit for it." ”

Shen Hongcai smiled slightly bitterly, of course he knew what Mo Dun meant, since this was not the Mo family's thing, this would not involve the dispute between Confucianism and Mo, so that when he was questioned in the future, he would also have a reason to refute.

However, how can there be so much truth in this world, since he has decided to use Tianzhu numbers, he is already mentally prepared to face the storm.

Shen Hongcai understood it and secretly remembered it in his heart.

Turn around and write on the blackboard the table of multiplication formulas, as well as various methods of number crunching.

All the students can see that Shen Hongcai is in a hurry to teach, and it is obviously impossible to teach these knowledge in one class, but Shen Hongcai ignores these and throws them all out directly in class.

Everyone in Bingshe has a hunch that this is probably Shen Hongcai's last lesson!

Even though they already knew all this knowledge, everyone still listened extremely carefully and did not let go of the slightest.

Soon, a class ended.

Shen Hongcai put down the chalk in his hand and looked at all the inmates in Bingshe with a nostalgic face.

"Let's go!" Shen Hongcai opened his mouth, wanting to say something, but it converged into two words.
