Ning Xi walked around the coffee table and sat down beside her mother, leaning affectionately on her shoulder, "Which mother wants to listen to first?"

Lan Xi's left hand naturally landed on her daughter's waist and moved slightly, "Why is your girl's waist so thin?"

One sentence made Ning Xi blush, "Oh, mother, do you still want to listen?"

"Listen."

Lan Xi's eyes were filled with a smile, "You are already married to Xiaofan, why are you so thin? It's the same as when you were not married."

Ye Fan coughed dryly, "I blame me for this. Sister Lan, don't worry, I will train well in the future."

“Train?”

Lanxi smiled meaningfully.

This smile made Ning Xi blush, and even Ye Fan couldn't help but blush and quickly changed his words: "Teach, I've said it wrong just now."

Lan Xi didn't point it out, and continued the topic just now, "Xiao Xi, what do you know?"

In order to quickly eliminate the awkward atmosphere, Ning Xi did not keep it in a silence and quickly responded: "No matter whether it is the cracking steps of the xyq conjecture or the iu conjecture, there should be no problem."

"oh?"

Lan Xi's eyes flashed with surprise, "I didn't expect you to be so confident."

"certainly!"

Ning Xi nodded without hesitation.

Ye Fan interrupted at the right time, "Xiao Xi cracked the xyq guess without any problem. I also calculated it in my mind during the cracking process that day."

Upon hearing this, Lan Xi looked at her daughter with a smile, "Did you hear that? Xiaofan was also calculating when you cracked it. Did you have any..."

"No."

Ning Xi shook her head decisively, helplessness flowing on her pretty face, "It's not that I'm lazy, but that I don't have the ability to untie IU's guess. Not to mention untie it, it takes a long time for me to digest the things written by my brother."

After listening to his daughter's explanation, Lan Xi's eyebrows were puzzled, "Is it really that difficult to guess?"

"In theory, the iu conjecture and the xyq conjecture are the top ten mathematical conjectures. Even if the iu conjecture is more difficult, it will not be that much difficult, right?"

“As for.”

Ning Xi's answer this time was more decisive.

Ye Fan raised his hand, "Sister Lan, this is indeed true. On the surface, although the iu conjecture and the xyq conjecture are both the top ten mathematical conjectures, the iu conjecture is not comparable to the other nine conjectures."

"Maybe you don't understand this very well. I'll give you the most intuitive example."

Lan Xi nodded, "You said."

Ye Fan thought for a while, "Although the difficulty of the nine conjectures except the iu conjectures among the top ten math conjectures is different, they are not very different. You can use scores to describe them more intuitively. If the simplest of the nine conjectures is 10 points, the most difficult conjecture can reach 13 points or 14 points."

"What about the iu guess?"

Faced with the mother-in-law's question, Ye Fan carefully considered it in his heart and gave the answer, "The iu conjecture can almost reach about 95 points, which means that the difficulty of the iu conjecture is almost equal to the sum of the difficulties of the other nine conjectures."

Lan Xi stared at her eyes wide and did not come back to her senses for a long time.

She knew that the difficulty of the iu guess was very high, but she never expected it to be so outrageous.

Ning Xi sighed and added in a low voice: "Actually, I think what my brother said is still a bit conservative. According to the criteria he just scored, I can give iU guess 150 points."

Lanxi: "…"

Here comes one more exaggerated!

Is one conjecture more difficult than the other nine conjectures combined?

It's really unimaginable!

Ye Fan waved his hand, "It's not that exaggerated."

"Not exaggerating at all."

The reason Ning Xi said this is because during Ye Fan's coma, she tried to crack the iU guess and experienced what it means to have no idea how to start, and finally gave up.

Only by trying it can you know the horror of the iu conjecture!

Ye Fan did not argue with Ning Xi about this issue anymore, and smiled politely at Lan Xi, "Anyway, the difficulty of the iu guess is very high, and it is more difficult than the world imagines. Otherwise, I would never have been slapped in the face in public at school that day."

"Slap in the face in public?"

Facing Lan Xi's puzzled gaze, Ye Fan gave an explanation, "Did Sister Lan forget it? I let it go before I started to crack the iu guess and wanted to untie it in a short time, but it took more than ten hours in the end."

The depths of Lan Xi's eyes were filled with speechlessness, "Do you call this slapped in the face?"

"Isn't it?"

Ye Fan's rhetorical question made Lan Xi silent for a while.

In response to this, Ye Fan looked innocent and looked at Ning Xi with an inquiring look.

Ning Xi rolled his eyes back, but in fact she understood her mother's psychological activities at this time.

Maybe in Ye Fan's opinion, he didn't say anything wrong, but others are easily stimulated.

I just described the difficulty of the iu conjecture, and then I said that it took me more than ten hours to crack the iu conjecture...

This is indeed too Versailles!

The key is that we can't refute anything, because these words seem to be very Versailles are indeed what Ye Fan really thinks.

What can she say about this?

Go and comfort him?

Forget it, she is obviously the one who was injured!

Lan Xi sighed deeply, "Xiaofan, pay attention to the method when chatting with me in the future. Sister Lan is old and can't stand the stimulation."

Ye Fan was confused, "Did I say something wrong just now?"

Lan Xi didn't know what to say, so she could only change the topic, "By the way, since the iu guess is so difficult, are you sure about your cracking process?"

"Sister Lan wants to hear the truth or the lies?"

"Of course it's the truth!"

Ye Fan's eyes were filled with confidence. Just as he was about to answer, a sentence popped out of thin air in his mind, and then he said it in a strange way, "Either you can't calculate it or you can't be wrong!"

"Boom--"

As soon as he finished speaking, a bolt from the blue came from the outdoors, which made the eardrums roar in the three of them.

Lan Xi and Ning Xi are worthy of being mother and daughter. Faced with the sudden thunder, the two reacted almost exactly the same. They shrank their necks at the first time, and the next second, they instinctively hugged each other tightly.

The mother and daughter collided, and turned their heads to look at Ye Fan in a tacit understanding.

This made Ye Fan a little at a loss, and in fact he was also wondering.

What happened just now, and why did such a sentence suddenly pop up in my mind?

It also brought a bolt from the blue, as if God was warning him!

If this is true, then this thief is too domineering.

Nowadays, I can’t even say anything?

Lan Xi took the lead in speaking out, "Xiaofan, can you agree to Sister Lan for something?"

"sure."

Ye Fan's eyes were curious, "Sister Lan said it straight, as long as I can do it, I will go through fire and water without hesitation!"

"You don't need to go through fire and water."

Lan Xi swallowed his saliva, with a little cautious tone, "Can you stop pretending in the future?"

"ah?"

Ye Fan was stunned on the spot and didn't react for a while. According to Lan Xi's usual cultivation, he shouldn't be able to say such words.

For a moment, his eyes were full of doubts, "Why?"
