Xiao Yu's voice rang in everyone's ears.

Except for Cheng Chumo's expected appearance, including Qin Huaiyu and Changsun Chong, they all looked at the piece of rice paper on the table with a confused expression.

"Chickens and rabbits in the same cage?"

The eldest grandson asked subconsciously.

"Hmm."

Xiao Yu glanced at Changsun Chong lightly and continued.

"This is an arithmetic problem that our princess has worked on for three all-nighters, and if any of you can solve this problem, then this test will be passed!"

"Ahem......"

As soon as Xiao Yu's words fell, Cheng Chumo looked at the latter and coughed.

The implication is that you are talking nonsense in front of the copyright owner, is it okay that the princess came up with it?

“……”

Xiao Yu was stunned for a moment, and then his face was slightly red and he didn't dare to look at Cheng Chumo.

just lowered his head and told everyone again.

"You all have pen and ink in front of you, and it's still a stick of incense for a limited time."

After speaking, Xiaoyu buried his head and left.

"Hey ......"

Cheng Chumo looked at the rice paper on the table and grinned.

The topic of 'chickens and rabbits in the same cage' is still quite difficult in this era, but if a certain amount of time is given, Datang also has capable people who are proficient in arithmetic who can calculate it, and even people who know a little bit of arithmetic can put it together to come up with the correct answer.

But here's the problem......

It's not that Cheng Chumo looks down on anyone, it's just that everyone who is doing it is a Muggle!

"Brother Cheng."

Qin Huaiyu on the side looked at Cheng Chumo and grinned, and immediately smashed the latter.

"I see you're smiling so happily, what are you going to do?"

"Yes."

Cheng Chumo didn't want to hide the latter, and nodded with a smile.

"This ......"

Qin Huaiyu couldn't see through this childhood friend.

"Tell me honestly, who taught you all this?"

"How can you compose poetry, you will also do this math problem, you tell me what else will you do?"

"Hey......

Cheng Chumo smiled slightly.

"There are a lot of them anyway, but if you ask me who taught me this, no one really taught me."

"It's all my own understanding!"

"Fart!"

Qin Huaiyu glared at Cheng Chumo.

"If you want to say that a loser is a bastard, this is your own understanding, I will definitely believe it, but if you want to say that these skills are also your own understanding, I don't believe it if you kill me!"

"Fuck off!"

Cheng Chumo glared at the latter with a dark face, and sighed helplessly.

How can this man be like this, he doesn't believe the truth, and he has to force himself to lie.

"Forget it, I won't pretend, I met a white-bearded old man a few years ago, and he taught me all these skills!"

“……”

Qin Huaiyu was stunned.

"Where's the old man?"

"Wander the world!"

Cheng Chu answered without thinking.

“……”

Qin Huaiyu was silent, then raised his head and stared at Cheng Chu, muttering a curse to the latter.

"God is really sleepy, how can you meet a noble person with such a thing?"

"Hey......"

Cheng Chumo: ......

"How can you talk, isn't it good to scold me in front of me?"

Boom!

Qin Huaiyu slammed his fist into Cheng Chumo's chest.

"What's so bad?"

"What kind of friendship do we have, when I was a child, I urinated on a bedding, and now you are hypocritical with me here?"

"Roll the calves!"

Cheng Chumo threw a punch at the latter with a dark face.

As soon as he turned his head, he saw Changsun Chong, who was sitting on the side, his face was a little pale, and he was holding a brush and looking at the rice paper in front of him in a daze.

Immediately gave Qin Huaiyu a look.

"Oh~"

Qin Huaiyu looked at the side, and immediately understood what Cheng Chumo meant.

"Ahem......"

Stretched out his hand and patted the stunned eldest grandson Chong.

"Brother?"

"Huh?"

The eldest grandson shuddered for a while, and the ink on the tip of the pen 'ticked' and fell on the rice paper, gradually infiltrating a large black dot.

"What's wrong, Brother Qin?"

The eldest grandson Chongqiang calmly put down the brush in his hand and turned his head.

"Minor problem!"

"You show us this topic, why don't I have a clue?"

Qin Huaiyu asked the latter seriously.

"This ......"

"This problem is actually not difficult, that is, I have to solve the part of this problem that interferes with my judgment first, and it takes a bit long to solve, but as long as it is solved, it will be a matter of time for this arithmetic problem to be calculated!"

"It's not that hard!"

The big words just now were blown out, how could Changsun Chong say that he wouldn't?

can only bite the bullet and talk nonsense seriously to Qin Huaiyu.

"Huh?"

Cheng Chumo interjected innocently.

"Really?"

"This topic is so skillful, you can't even do it, Brother Chong, so how can we fix it?"

"Hehe......"

The eldest grandson wiped the cold sweat from his head.

Cheng Chumo praised himself twice and three times, and now it seems that he has been roasted on the fire and can't get off the stage, so he has to smile embarrassedly and perfunctorily.

"It can be done, it can be done."

"Just a while!"

……

When the eldest grandson was scratching his ears and cheeks, he was panicked but didn't have a clue.

The little eunuch who had been in charge of delivering the word walked into the pavilion quickly with a piece of rice paper with a copied title, and then stood in front of Li Shimin.

"Your Majesty......"

Li Shimin raised his eyebrows.

He smiled, took the rice paper behind him, and unfolded it in front of all the ministers.

"Let's take a look."

"This is my little Changle for everyone, you can also take a look at this question together, and it can be regarded as a pleasure for our monarchs!"

"Haha......"

When everyone heard this, they all approached Li Shimin with a smile, wanting to see what Li Lizhen's second test was.

But when everyone leaned their heads over, they were dumbfounded.

"Chickens and rabbits in the same cage ......"

"This ...... What's this? ”

"I haven't heard of it, what kind of test is this?"

The ministers discussed it in a gossipy manner, but Li Shimin looked calm, just holding the rice paper in his hand and twitching the corners of his mouth from time to time.

I don't know where this daughter found this topic.

Anyway, Li Shimin, who got this topic three days in advance, hasn't figured it out until now, and he doesn't even have a clue.

Du Ruhui frowned, and his eyes lit up after reading the whole topic.

"This ......"

"It's an arithmetic problem!"

"Oh?"

Wei Chi Laohei was stunned when he heard this, and looked at the latter with a smile and said.

"Or Du Xiang has insight, then hurry up and solve this problem in front of our old buddies, so that we can open our eyes!"

"Uh......"

Du Ruhui grinned.

"I won't!"

“……”

"You don't know what you're talking about there, I thought you'd do it!"

"Hey......"

Yu Chi Lao Hei suddenly frowned and said impatiently.

"What are you talking about?"

Du Ruhui frowned and scolded with a smile.

"I won't know someone who can do it, don't I?"

"I know one, Plenum!"
