Ning Xi is speechless.

At this moment, a sound came from the TV screen.

At the door, Zhuang Li brought a moving blackboard, and several lines of mathematical symbols and formulas were written on it.

Ye Fan raised his eyebrows.

What does it mean?

Test his math?

Before Ye Fan could think too much, Zhuang Li put an hourglass on the ground and started time counting, "Son-in-law, you need to solve this math problem within half an hour."

Ye Fan smiled confidently, "It's easy to say, it's just a math problem."

Ning Xiangtian reminded lightly: "Yes, it's just a math problem, just a math problem about energy reversal, and it is also known as an unsolvable problem. You should have heard of its name."

Ye Fan was stunned and looked at the blackboard. After reading the contents on the blackboard, he couldn't help swallowing, his face filled with disbelief, "Energy reversal and purification?"

Ning Xiangtian nodded with a smile, "That's right."

Ye Fan: “…”

This math problem has appeared for more than twenty years. For many years, countless maths have been putting in countless efforts, but unfortunately no one has successfully solved it.

Because of this, this question is also called an unsolvable question!

Ye Fan never expected that Ning Xiangtian would use this question as a test for him, and he also asked to solve it within half an hour.

this……

Too perverted!

You know, this is the first level, and there is another level waiting for him later.

Thinking of this, even though Ye Fan had already made some psychological preparations in advance, he still couldn't help but start to doubt his life in the face of such difficulties as his father-in-law.

"Dad, even if you want to test me, you have to find some normal questions, right?"

Ning Xiangtian's expression remained unchanged, "In my opinion, this question is normal. If you can't do it, I can give you another choice. Of course, I will inevitably despise you."

Ye Fan: “…”

Men can never admit that they can’t do it!

So, he gritted his teeth and said, "I won't give you the chance to despise me!"

The timing had already begun, and he did not dare to delay and shouted in his heart: "Lan Ying help me."

Lan Ying didn't say anything nonsense at all, and directly helped Ye Fan to cheat.

The thinking agile experience card is enabled!

Intelligence Amplification Experience Card is enabled!

The computing power amplification experience card is enabled!

Three prompt sounds sounded, and Ye Fan's entire aura changed drastically in an instant. The moment he picked up the chalk, his eyes were extremely focused.

Lingsiquan is activated!

Passive skills focus on enabling!

Five major amplification effects gathered together. At this moment, Ye Fan felt that he could see through the illusion, and the various essences of the world appeared in front of him.

He paused for a moment and raised his right hand.

Chalk draws cumbersome mathematical formulas on the blackboard, and the rhythm of the dada sound is very tight.

In the second floor room.

Jiang Shiqi stared at the TV screen with a wonderful expression and sighed: "Uncle Ning is really cruel and ruthless. He actually asked Ye Fan to solve the unsolved problem within half an hour. This is determined to make him look ugly!"

Ning Xi looked desperate, and she didn't expect her father to be so cruel.

This is a problem that mathematicians around the world have not solved in twenty years. No matter how genius Ye Fan is, he will never be able to successfully solve it within half an hour.

Too absurd!

Shen Li quietly came to the bed and sat down, whispering: "Sister-in-law, how much does uncle want you to get married?"

Ning Xi's pretty face was bitter and worried.

However, as Ye Fan solved the problem, her expression changed subtly.

Really solving the problem?

Five minutes later, Ye Fan had already written the blackboard with mathematical formulas, then picked up the blackboard eraser and wiped it off quickly, and then wrote again.

This operation is simply incomprehensible.

Ning Xiangtian was confused in his heart.

What is this kid doing?

Ye Fan did not explain and continued to write various formulas. The six boys standing behind him opened their eyes wide and their tender faces showed curiosity.

When half of the sand in the hourglass was left, Ye Fan stopped and wiped off the listed mathematical formulas with a blackboard eraser again. Finally, he wrote three rows of profound formulas under the blackboard question.

He threw away the chalk in his hand and felt extremely moved.

It’s so fierce to cheat!

Ning Xiangtian came to the blackboard with a puzzled look on his face, "Give up?"

Ye Fan turned his head with a smile, "Dad, this is my answer."

Ning Xiangtian glared at his eyes, "You boy are fooling me? How long has it been?"

Zhuang Li, who was standing beside him, silently added: "It took a total of 13 minutes and 52 seconds from the beginning of the cracking of the son-in-law to the end!"

Ye Fan waved his hand, "I have solved the problem since the specified time has not exceeded. Is this the first level considered passing?"

Ning Xiangtian looked dark, "I suspect you kid is just writing Hu."

Ye Fan looked calm, "Is there any evidence?"

“…”

Ning Xiangtian's chest was blocked, but before he could speak, Ye Fan continued: "If you don't believe it, you can verify it, but the verification takes a long time and it is probably impossible to complete it in just a few months."

"Boy, you're ruthless!"

No matter how unhappy Ning Xiangtian was, he could only accept this fact, "I am careless this time, and I will never leave you another opportunity to take advantage of the next level!"

Hearing this, Ye Fan emphasized very seriously: "Dad, I really figured it out."

Ning Xiangtian stared at him, "Okay, stop talking nonsense."

Ye Fan shook his head and laughed, but didn't explain anything. He just turned his head and told Zhuang Li, "Put the blackboard well and don't move the formula above."

After saying that, he brought six boys into the villa.

At this time, a burst of discussion sounded in the room on the second floor.

Luo Yumeng: "It's so shameless!"

Su Ke: "I have to admit that Ye Fan has really strong reaction ability on the spot. If it were me, I would definitely not be able to think of such a way to pass the test."

Jiang Shiqi: "What are you writing about this? You can't understand it at all!"

Qingdai: "Teacher Ye is so smart!"

Nanxing: "Withful!"

Shen Li's eyes turned and made a final summary, "No matter whether it is black and white cats, a cat that can catch mice is a good cat; similarly, no matter what method is used, as long as it can pass the test, it is a good method!"

Only Ning Xi said nothing and recalled the three lines of formulas on the blackboard just now, with shock and shock in her eyes.

Although she only understood the basics, her intuition told her that Ye Fan was likely to have really solved this world-famous unsolved problem.

And the whole process took less than fourteen minutes...

Ye Fan took the people into the living room and walked directly towards the stairs.

"Slow down."

Just as the group arrived at the stairs, Ning Xiangtian's voice came from behind.

Ye Fan stopped and turned around to look at Ning Xiangtian who was walking slowly, "The second level of test isn't it?"

"That's right."

Ning Xiangtian did not go around the corner and pointed to the coffee table in the distance, "Come with me."

When Ye Fan came to the coffee table, a look of surprise flashed in his eyes.

There were hundreds of embroidery needles and hundreds of red threads on the coffee table.

Ning Xiangtian showed a confident smile, "The second level of test is very simple. You only need to put a hundred needles and threads in one minute and pass it. Isn't it very simple?"

"Dad, do you have any misunderstandings about the word "simple"?"

Ning Xiangtian took out an hourglass, "Is this important?"

It is clear that I am just making things difficult for you, what kind of expression can you do to me?

Ye Fan curled his lips without leaving any trace, "Well, it's really not important; this kind of test may stump ordinary people, but it's really very simple for me."

"You're not afraid of the wind blowing your tongue!"

Ning Xiangtian reminded him coldly, "Did you hear it wrong? It takes a hundred needles and threads to pass the test in one minute, not ten or one."

"Isn't it just a hundred needles and threads in one minute?"

Ye Fan showed a harmless smile on humans and animals, "Dad said it's very simple, it must be very simple."
