Zhao Qiumeng lowered his head and gently pushed his glasses, which inexplicably carried a hint of ghost and animal feeling, which made Mu Yan shudder a little.

Because of the reflection, Mu Yan couldn't see Zhao Qiumeng's eyes clearly, and only felt that he was entangled in something cruel and unkind.

Finally, Zhao Qiumeng spoke: "This is a textbook for all subjects from elementary school to senior high school, and we have gone through them one by one." ”

"One by one?"

"Yes, one by one."

Mu Yan glanced at the mountain-like textbook, and the one on the top was impressively written "Nature", okay?

How many lifetimes has she lived, does she even have to read this "children's book"?

Mu Yan's eyes widened in disbelief, she was the only one who brought others a sense of fear like they were on the edge of an abyss, but at this moment, it was really feng shui in turn......

She couldn't help but ponder, was the mission of this life specifically for her?

Mu Yan refused in his heart, and couldn't help but raise his eyes to look at Mu Zimo on the side, and was about to blurt out a sentence of "relatives", but the latter actually pursed his lips and smiled, dropped the sentence "study hard" and left decisively! Finish!

Let's go!!!

Let's go......

Mu Yan's expression froze, and the door of hope was slowly closed.

With a soft sound of "Kala", Zhao Qiumeng picked up the "Nature" textbook and smiled at Mu Yan, and Mu Yan officially fell into the dark abyss of learning......

……

Zhao Qiumeng originally thought that it would take two years or even more to consolidate all the knowledge for Mu Yan, but after just two months, she would be useless.

"Well, the final answer to this question is that x has a defined domain of 25."

"What about this one? It is known that the power function y=f(x) is the image passing point (27,3), which is discussed for its monotonicity. ”

"Monotonically increasing on R."

"What about this question? Let a be a real number, and the function f(x)=(x-a)²+|x-a|-a(a-1), and when a≥2, discuss the number of zeros in the interval (0,+∞) of f(x)+4\/x. ”

"Because f(x) increases monotonically on (a,+∞) and decreases monotonically on (0,a), f(x)min=f(a)=a-a²...... In summary, when a=2, f(x)+4\/x has a zero point x=2, and when a>2, f(x)+4\/x, there are two zero points. ”

Zhao Qiumeng was silent for a long time before he took a breath lightly, stared at Mu Yan with burning eyes, and said, "Completely correct......"

Although the difficulty of this question is not high, without using scratch paper, she deliberately hid two prompts, but Mu Yan was able to answer the answer very quickly, and even the process was so accurate.

It's incredible!

Mu Yan is simply a genius, no, a ghost!!

Not only does she have a super memory, but her ability to think is even stronger to the point of being terrifying.

In fact, there are not many people in the world who have extraordinary memories and can never forget, but very few can really use this talent.

The brains of these people with extraordinary memories are like a supercomputer with unlimited storage space, but as the computer stores more and more things and information becomes more and more comprehensive, the computer's central processing unit will be overwhelmed, running slower and lager.

They often spend a lot of time searching in their minds to come up with the answers they want, which is why many "geniuses" with extraordinary memories will become mediocre in their later years, and their thinking ability is no longer enough to support their memory storage.
