"What about twenty-five times seven hundred and twenty minus sixty-five?" A voice rang out behind Merton.

"Seventeen thousand nine hundred and thirty-five." Merton subconsciously answered, but suddenly realized that Li Zhixiao's voice was replaced by an adult's voice, and the topic was too difficult for a seven-year-old child!

Merton subconsciously looked back and found that Li Shimin appeared behind Merton with a black face.

Merton couldn't help but feel a sudden feeling in his heart, this time the Great Demon King is really here.

"See Your Majesty!" Merton's heart was empty, and he quickly turned around and bowed.

"See Father!" Li Zhi's little face turned pale with fright, for him, it was Li Shimin who was most afraid, and it just so happened that he was caught by Li Shimin for tricking Merton to help him with his homework.

Li Shimin's face was gloomy, and he was about to get angry.

Li Zhi's liver trembled carefully, and he couldn't help but set his eyes on his last magic weapon, Princess Jinyang.

"Father!"

Jin Yang's soft voice sounded, and he twisted and trotted towards Li Shimin.

"Hahaha! Son, why did you sneak out again! Li Er was like a Sichuan opera veteran, and immediately changed from a black face to a smiling face, and hugged Princess Jinyang who threw herself into his arms.

"Brother Jiu said to bring his son to see the Great Demon King! said that after the son enters school, he will know how terrible the Great Demon King is? Princess Jinyang said coquettishly.

Li Zhi's face turned pale suddenly, and he was completely betrayed.

"The Great Demon King?" Li Er glanced at Morton contemptuously, as if to say, as far as he can still be called the Great Demon King, a small catfish is almost the same.

"His Royal Highness King Jin is laughing!" Merton laughed dryly.

"Yes! Yes! Kidding me! Li Zhi hurriedly smirked and nodded.

When Li Er arrived, all the princes quickly got the news and immediately poured out.

"See Father!" Under the leadership of Li Chengqian, who was the leader, the princes said in unison.

Li Chengqian took the lead, Li Zhi, who was the latest to enter the school, was ranked last, and the nine princes stood neatly.

Merton looked at the nine princes who were arranged from behind, not including the princes who were still in their infancy in the harem, Merton couldn't help but smack his tongue, and admired Li Er's stallion attributes a little, if this is in an ordinary family, he can't afford to raise it at all!

Li Chengqian looked at Merton, couldn't help blinking, nodded slightly, and the other princes also looked at this strange boy with curiosity.

Merton showed his signature smile and clasped his fists and saluted: "Mojia Village Merton see all the princes!" ”

"Merton!"

The rest of the princes couldn't help but move slightly, the little fat man behind Li Chengqian actually showed an excited look, and the princes behind him showed resentful expressions one by one, among which Li Zhi's resentment was the deepest.

In Li Zhi's short school experience, he originally thought that endorsement was the most painful thing, but since Li Chengqian learned arithmetic from the outside, Li Zhi found that he couldn't memorize the endorsement anymore, just continue to memorize, but if he can't do arithmetic, then he can't scratch his scalp!

In his mind, it was not the Great Demon King or something that could come up with such a perverted topic.

Inside the Chongwen Museum.

Li Shimin was sitting precariously, and next to him, a gray-haired old man was sitting down, looking at himself with interest, and Merton nodded and smiled at him, which was regarded as a greeting.

The old man was stunned for a moment, he didn't expect to get a response from Merton, and he also smiled and nodded.

"Wei Aiqing! How are the princes progressing in their studies? Li Shimin asked to the next one.

Merton's expression moved, his surname was Wei, and he was able to sit down in front of Li Shimin, and there was only one person who had such treatment - Wei Zheng.

"Under the avoidance, the schoolwork of the princes is progressing extremely smoothly, and even the youngest Nine Emperor Princes have memorized the thousand-character text proficiently." Wei Zheng replied.

"Oh! What about arithmetic? Li Shimin asked.

Wei Zheng smiled slightly bitterly: "Back to Your Majesty, the new style of arithmetic is easy to learn and difficult to master, and all the princes are still groping, so there must be improvement in time." ”

In fact, Wei Zheng has already said that in addition to Li Chengqian, who was taught by Merton himself, Li Tai, the king of Wei, who is very talented, has learned the best, and the other princes can be said to be a mess, especially Li You, the mischievous king of Qi, who is simply bullshit.

"Easy to learn, hard to master?" Li Shimin said with a flash of expression. "Just now outside the Chongwen Pavilion, I saw Merton, but he answered as soon as he opened his mouth to arithmetic. Could it be that Merton couldn't try? ”

When Morton heard this, he immediately felt that he was as wronged as Dou E, your own son did not learn, and even said that I did not hide my secrets and did not teach.

"Oh! Mo Xianbo still has such a stunt? Wei Zheng said in surprise.

"Back to Zheng Guogong's words, it's not that the kid hides his secrets, this is the method of lightning mental arithmetic, and you need to learn arithmetic for a period of time before you can start practicing."

"The method of lightning mental arithmetic? The Mo family still has such a stunt! Wei Zheng said with a moving expression.

"Back to my father! The child also wants to see the mental arithmetic method of Mo County, and I wonder if I can ask Mo County Uncle to demonstrate. The little fat man Li Tai said excitedly.

Wei Zheng's expression moved and said: "Then it would be better to let the nine princes come up with the questions in turn and let Mo County Bo answer!" ”

"Don't you keep complaining that arithmetic is too difficult, now there is an opportunity in front of you, then give out the questions you think are the most difficult, let Merton answer them, and see if the questions are too difficult or you haven't learned well!" Li Shimin said in a deep voice.

"Yes!"

All the princes couldn't help but show excited expressions, and all of them were eager to try.

So before Merton opened his mouth, a competition was so happily decided.

Li Er looked at the princes who were excitedly asking questions, a smile appeared on the corner of his mouth, and he turned his head to the listless Merton and said, "Merton, if you answer one game wrong, then we will calculate your recent account." ”

Li Shimin bared his white teeth and threatened.

Merton suddenly had a cold war, and hurriedly cheered up, this time he couldn't even deal with it, and the problem of offending the prince would be solved later! At present, it is better to pass the level of Li Shimin first.

Soon all the princes finished the question, and looked at Merton eagerly one by one.

Li Zhi took the lead in the question, but unfortunately his arithmetic level was limited, and the knowledge he learned was within 100 digits, although he had tried his best to come up with a mixture of five numbers to add and subtract, but Merton still opened his mouth to give his answer at the first moment when Li Zhi finished reading the question.

"That's right!" Wei Zheng took the calculation plan a few times, nodded and said.

"Hey!"

Accompanied by Li Zhi's disappointment.

The rest of the princes all showed extremely interested eyes, this was so simple in the mouth of the Mo family in such a troublesome calculation.

Lightning mental arithmetic is really not simple.

Later, although the rest of the princes racked their brains to solve the problem, they still did not have the slightest trouble caused by Merton.

Soon, the third prince Wu Wang Li Ke was also defeated, and his problem was that the mixed operation of multi-digit addition, subtraction, multiplication and division gave ten numbers at once.

"Three hundred and twenty-four!"

Merton gave the answer in the three-breath time.

"Wow!"

The princes couldn't help but exclaim in surprise.

In three breaths, I can't even finish writing the question! And Mo Jiazi has already written out the answer.

"So fast!" Wei Zheng looked at the three-digit calculation he had just dialed and was shocked.

At this moment, even Li Shimin's eyes were full of brilliance.

"Moxian Bo arithmetic is really unique, Xiao Wang admires it!" Wu Wang Li Ke said admiringly.

"His Royal Highness King Wu is polite, it's just a matter of taking advantage of the calculations!" Merton hurriedly said modestly.

He is also deeply interested in this tragic prince, Wu King Li Ke has the royal blood of the Sui and Tang dynasties, which can be described as the most noble bloodline in the world, but that is also his deepest original sin, and he was finally unjustly killed.

"Xiao Wang Li Tai has seen Uncle Moxian!" The little fat man Li Taiwen said politely.

"I've seen His Royal Highness King Wei!" Merton did not dare to underestimate this famous figure in history, according to historical records, Li Tai, the king of Wei, was a standard scholar!

has a good background and hard work, it is simply abused all the princes, no wonder he is deeply loved by Li Shimin, and even threatened Li Chengqian's position as the crown prince for a time.

"This time, Qingque is interested!"

Knowing his son Mo Ruo's father, Li Shimin saw Li Tai's expression, and knew that Li Tai must be holding back his big move.

Sure enough, Li Tai opened his own topic, and the audience was in an uproar, his topic only had two numbers, and the two super long numbers were divided.

"One, five, eight, seven, six, five, nine, three, seven, eight, two, divide by six, one, eight, four, nine, five."

"Wow!"

The audience was in an uproar, how could such a long number be calculated.

All the princes looked at Li Tai with admiration, or the second brother was powerful, this time it depends on how the Mo family calculates.

Wei Zheng looked at the calculation plan in his hand and looked around blankly, not knowing how to start, Li Shimin also looked at Merton with interest, wanting to see a little panic in Merton's eyes.

"Two-five-six-six-nine-six-six." After only five breaths, Merton suddenly looked up and gave the answer.

"Wow!"

"How is that possible?"

"How did you figure out the answer so quickly!"

………………

Everyone was in an uproar. Li Shimin stood up even more suddenly, looking at Merton in disbelief.

"Second brother, is Merton's answer correct?" Wu Wang Li Ke asked in disbelief.

Li Tai twitched his face and said, "If I say that I made up a random question, and I don't know the answer myself, do you believe it?" ”

In the end, after a quarter of an hour of calculation, Li Chengqian and Li Tai finally calculated this extra-long question.

"Correct answer!" Li Chengqian looked at the answer in his hand and exhaled heavily.

Suddenly, everyone was boiling, and they all looked at Merton in disbelief, such a large number was calculated in a short time, and the lightning mental arithmetic was simply a god.

Merton laughed secretly in his heart, what is this, you haven't seen some radio competitions in later generations, those topics are really perverted, and the atmosphere is so enthusiastic.

Merton lost eight princes in a row, leaving the crown prince Li Chengqian.

Li Chengqian looked at the title in his hand, sighed and said: "The arithmetic knowledge of this palace is all received by Moxian Bo, so I won't be ugly, and this palace will admit defeat!" ”

So far, Merton vs nine princes.

Win all.
