Chapter 6 Talent, Super Mental Arithmetic

Ye Yu looked over and over. This palm-sized thing has a diamond-shaped pattern on the back, which is very similar to a turtle shell, but it looks more primitive, and the most peculiar thing is that there are peculiar patterns on the turtle shell. .

There are many bean-sized, black and white dots all over the surface of the turtle shell, neatly arranged horizontally and vertically.

What is this? It looked very mysterious, and Ye Yu felt as if he had caught something good!

Ye Yu counted, these dots are very regular, there are three vertical and horizontal groups, the first row is two, nine, four dots, the second row is three, five, seven dots, the third row is six, One, eight dots.

emmm?????? Who is so idle, engraving the nine-square grid on the turtle shell!

Ye Yu threw the turtle shell directly on the bed. He thought it was a good thing, but who knew it was someone else's random work!

"Ask the system, this tortoise shell material is very comfortable to the touch, so it must be worth some money." Ye Yu sighed in disappointment.

"Congratulations to the host for stealing the Luo Shu! Increase the Dao value by 30 points!" The system's voice sounded, making Ye Yu startled.

"Luo Shu? System, you said Luo Shu just now? I don't read much, so don't lie to me!" Ye Yu's depressed mood became suspended. This is Luo Shu, a legendary thing!

"Luo Shu: There is a turtle named Xuan, and its armor has a picture, which is from heaven. It wears nine shoes, one on the left, three on the left, seven on the right, two and four for the shoulders, six or eight for the feet, with five in the middle, and the white circles in the five squares are all yang numbers. The black dots in the four corners are yin numbers. The source of yin-yang and five-element arithmetic is to calculate the sky and the earth, and calculate all things in the heaven and earth!"

The system's voice sounded in Ye Yu's mind, and it was rare to explain it to Ye Yu. It seems that this tortoise shell is unusual.

When Ye Yu heard this, he was pleasantly surprised. It was really another village!

The mood went up and down like a roller coaster, and before he could quickly calm down, the system's voice sounded in Ye Yu's mind.

"Host! Are you extracting the spirituality of the Rare Book?"

"extract!"

"The extraction is successful, congratulations to the host for obtaining the talent: super mental arithmetic."

From above the tortoise shell, a cloud of white light emerged and merged into Ye Yu's body.

A sense of enlightenment came to his heart, Ye Yu opened his eyes, and found that the world at this moment was very different, and the whole world seemed to be digitalized in Ye Yu's eyes.

"Wooden desk, length 187cm, width 70cm, height 110cm, table top inclined 2??????"

Ye Yu turned his eyes to the desk, and all the information on the desk was captured by Ye Yu in an instant.

"This damned profiteer, he promised to be two meters long, but he was missing 13 centimeters! There is also a table with short legs!" Ye Yu cursed secretly.

Ye Yu moved his gaze to the test paper on the table, with the last math question still empty.

"On the plane rectangular coordinate system, the vertex of the parabola c is at (-1, 1), passing through the point A (2, 2), and its focus is on the F axis, find 1, ???2, ···, 3· ··"

Originally, Ye Yu pondered this question for a long time and never came up with it, but now, at a glance, the answer has already emerged in his mind!

So awesome! Super mental arithmetic, just cheating!

Whoa!

The sound of the wind blowing leaves was heard outside the window, and it reached Ye Yu's ears, and a message emerged in his heart.

"The wind speed is 3.1 meters per second. After 0.5 seconds, it will pass through the gap in the window, blowing 138 hair strands on the left side of the forehead by 3 cm."

Reaching out his hand to press down the hair that was blown up by the wind, Ye Yu was stunned, this is all right!

"Stinky boy! Come to dinner, you're going to be late!" He remembered Ye Weiguo's voice outside the door, and woke up Ye Yu who was still intoxicated.

"The old voice, 62 decibels, the host has three minutes to clean up, otherwise there is an 80% chance of being pulled by the ears."

"emmm?????? here!"
