Soon, a fair-skinned, delicate-looking young man appeared in front of the three children.

The three little ones were very satisfied with their masterpiece.

"Brother." Bei Ji winked at Si Yan.

Oh, that one "brother" melted Si Yan's heart.

No wonder boys like to be called "brother".

"Brother." Xi Qing smiled and called out. Si Yan happily replied in a male voice, "Hey."

Very good, the voice is accurate, and it's impossible to tell if it's male or female.

“Stupid male.” Eastern Equator.

Si Yan: "..."

She still likes the soft and cute Beiji and the adorable Xiqing the most!

...

Hu Que said to Hu Yong, "The monkey tribe is weak and arrogant. They have no other skills besides climbing trees and doing arithmetic. Even so, they still act arrogantly while relying on our Black Tiger City. This time, we couldn't even invite a single monkey who can do arithmetic. It's infuriating!"

"Forget it, don't be angry." Hu Yong patted Hu Que on the back. "You know, arithmetic is a great skill."

After Black Tiger Dark Flame built Black Tiger City, a group of powerful orcs gathered there.

The Orcs are strong, but they are all roughnecks.

Black Tiger City's Mingyan, however, had his own unique ideas. He wanted to develop some civilization in this rough Black Tiger City.

After all, with a larger city comes more orcs and more tribes that depend on it. This raises issues such as the rational allocation of resources and the overall management of supplies.

However, even Hu Yong, the greatest scholar in Black Tiger City, could only perform addition and subtraction within ten.

Dong Chi, who had transformed into a tiny snake, told Si Yan everything he had overheard.

Si Yan's eyes gradually brightened.

Arithmetic? Hey, she knows how to do this problem.

What kind of arithmetic do you need? Addition, subtraction, multiplication, and division for numbers over 10,000? Geometry? Calculus?
