When Bai Yun heard this, he immediately squatted down, picked up a branch, brushed the sand and gravel on the ground aside, and stumbled and calculated.

Ning Yuchu clasped his hands on his shoulders and patted his index index: "Ten, nine, six, two......"

Bai Yun paused, and said happily: "The old man is forty-nine years old, and the grandson is twenty-seven years old!" ”

Ning Yuchu raised his eyebrows and continued: "The last question, there are three friends who went to buy pen, ink, paper and inkstone, one set is ten taels of silver, and the three of them each took out ten taels of silver to make up for thirty taels to the boss, the boss said that the opening is a big reward, buy two get one free, let the shopkeeper return ten taels of silver, the shopkeeper is a black-hearted, four taels, and then each person returned two taels of silver. ”

"Literally, that is, the three of them each spent eight taels of silver to buy stationery, but the three of them spent eight taels of twenty-four taels, plus the four taels that the shopkeeper was greedy for, it was only twenty-eight taels, where did the remaining two taels go?"

Bai Yun was asked.

He scratched his chin and looked down again.

But the more you count it, the more sweat you get on your head.

How could there be less than two taels?

No, no, no.

This time, Ning Yuchu didn't rush to count, jumped on the wheel, bent on one knee, and shook lightly with the other foot.

"Count slowly, you have time."

The morning sun is gradually rising, and the temperature on the ground is getting higher and higher.

Bai Yun's entire back was wet, and even the little guy sweated for him.

After Ning Yuchu fell asleep for a long time, he opened one eye and prepared to jump out of the carriage: "It seems that you have learned ...... in the past three years."

Bai Yun's eyes lit up, and he jumped up excitedly: "There you have it!" There are no such two taels at all, no, the topic changes the concept. The three of them actually only ate twenty taels of noodles, and the three of them had eight taels and twenty-four taels, which actually included the four taels that the shopkeeper was greedy for, so one person had already shared the silver taels that the shopkeeper was greedy for, so it was right to return the six taels! ”

When he finished speaking, his whole body was gasping, but his eyes lit up amazingly, waiting for the final judgment.

Ning Yuchu's cold face suddenly smiled in his apprehension: "Congratulations to classmate Bai, you are out of the school." ”

Bai Yun stood there dumbfounded, muttering and repeating: "I did it, I got out of school, I did it......"

For three whole years, he worked day and night on the questions, calculating the cost, and the students did not dare to relax for a moment.

Even if he successfully completed his studies, when he saw the family's carriage, he was still not confident in his heart, and he felt that the road ahead was uncertain, and he did not know whether he could meet his father's requirements and become a qualified and excellent heir.

It wasn't until now that Ning Ye's words made him settle down.

His heart was suddenly surging, full of anticipation of unknown challenges.

Ning Yuchu jumped out of the carriage and said with a smile: "Bai Yun, even if you don't believe in yourself, you have to believe in the master, the people who are taught by the master are not bad." ”

It turned out that Ning Ye had long seen through his worries.

Bai Yun was so moved that he gritted his teeth to stop the sourness in his nasal cavity.

Ning Yuchu patted him on the shoulder and said, "I wish you to be better than the blue, go, take care." ”

Bai Yun nodded heavily, plucked up the courage to hug him hard: "Master Ning, goodbye." ”

When the other party jumped to push him away, he snickered and ran away and jumped into the carriage.

The wheels gurgled and turned, and Bai Yun smiled and waved his hand at him: "I have time to go to Bai's house to see me!" ”

Ning Yuchu didn't look back, and after waving his hand with his back to him, he rubbed his eyes into the sand.

"I know, I've said it a hundred and eighty times, it's really verbose."

Until the carriage turned a corner and no one could be seen, Bai Yun withdrew his hand and turned around and cried like a dog.
