The days when the four daughters and Su Li got together seemed to be a long time ago, which made Su Li feel emotional.

After experiencing the initial embarrassment, the four girls wrapped themselves around Su Li, asking Su Li long and short questions, eager to tell all the things that happened after Su Li went to Jiuyuan Pavilion.

"Don't make trouble, it's so late, I have to marry Qianqian girls tomorrow, if someone comes to inspect at this moment, I'm afraid ......" Su Li said with a smile.

"Is it difficult for you, are you afraid that someone will find out about our appearance and treat us as spies of Gu Yilou?" Yun Yi asked with a grin.

…… The nightingale emerged from the shadows, and the corners of his mouth showed an imperceptible sneer: "If this is the doubt, don't worry, once the people within a radius of three miles approach, they will not be able to escape the detection of my nightingale, and no one will appear, unless it is a dead person." By the time she had said the last sentence, her eyes were fierce enough to kill any coward.

Su Li and the other women couldn't help but gasp, and the nightingale appeared unnoticed, fortunately, under Su Li's explanation, they understood: the current nightingale is not an enemy, just a bodyguard of Su Li.

Yu Lian smiled softly, bowed down to the nightingale and said, "Sister Nightingale, then I have to thank you." ”

"Miss Yu......" Nightingale sighed slightly: "It's okay, this is what I should do." The back of her turning away was like an owl in the night, which made people feel abrupt.

"Speaking of which, are there any other people, just the four of you? It's a pity, I originally prepared eight sets of the bride's clothes......" Su Li pretended to look out.

Yu Wenxin "bah" and said: "Who is going to be your bride, don't be affectionate, I'll come, it's just ...... It's just a drop-by. She panicked, and she couldn't even tell a lie, how could she go all the way from Yujia Villa to a war-torn place like Jizhou City.

Su Li pondered for a while: "Otherwise, let's make a bet, I, Su Li, rely on my strength to conquer you one by one, if I win, you have to listen to me obediently, how about it?" ”

"Who would grant you such an unreasonable request?" Yu Wenxin shook his head proudly.

"Conversely, if anyone wins me, I will obediently listen to you." Su Li smiled, noncommittal.

This proposal finally aroused the interest of the women! Let Su Li, the Great Qi Demon Man, listen to his own words, and after thinking about it for a while, he felt that it was quite enjoyable.

"Okay, we agreed." The four girls said in unison.

"But, wait, you go back to what you said earlier, you just said that there are only four of them, so who else do you want to come, you say, we will bring someone for you next time, provided that you have another time." A cold smile bloomed on Yun Tian's face, and her dark eyes made it impossible to guess what she was thinking.

Su Li laughed: "Sister Yun, I haven't seen you for a few days, and you have become a lot more cold again." Come, let me try it, have your martial arts recovered in the past few months? ”

Su Li was despicable, and before he finished speaking, his figure had already moved, and when he finished speaking, his hand was almost touching Yun Tian's shoulder.

Fortunately, Yun Tian didn't know Su Li on the first day, from the moment she entered the door, she was already guarding against Su Li's salty pig hand attack, who expected that Su Li would directly confront her with martial arts. If it was changed to before, with Yun Tilt's Nine Abyss Array, it would definitely not be difficult to win against Su Li, but her martial arts had degraded to the level of one percent before, and even if she could recover under careful adjustment, it would only be restored to about three percent of her strength.

Yun Qian wants to deal with the current Su Li with the strength of thirty percent, but it is far from enough! The current Su Li has experienced many hardships in the field of life and death, and even fought with Shadow Feather, and his combat experience is no longer the same as it was at the beginning.

"I lost......" Yun Tian said calmly.

Once you admit defeat, according to the rules of the competition, the other party should stop in time, but Su Li doesn't care about this!

"Huh? What you say, it's too soft, I can't hear it. ”

Su Li grinned, seeing his groping pig hand plan, how could he let go easily?

Seeing that he was about to succeed, he was stopped by Yun Yi single-handedly, so he had to give up.

"What's the matter, is there still a two-to-one saying in martial arts?" Su Li was grabbed by Yun Tian's soft little jade-like hand, and there was an unbearable itch in his heart.

Yun Yi grinned and said, "Where is my sister going to compete with you, it's obvious that you unilaterally forced it." If it's really itchy, you can find me here to play prestige. ”

Although Yun Yi's kung fu is not superb, it is not an opponent that Su Li can easily match.

Su Li laughed and said: "It's boring to compete with martial arts all the time, you are a talented woman in Guyilou, it is more suitable for me to fight with you." ”

Yun Yi heard that Su Li was going to fight with him, and his eyes suddenly lit up: "That's good, it's not easy for me Yun Yi to meet an opponent, and there are even fewer top-notch opponents like you, count me for sparing you, you can solve the problem." ”

Su Li smiled and thought: If I ask the question, do you have any way to live, from stochastic modeling topology to high-number line algebraic probability theory, which one can't blow you up a few streets?

Yun Yi's knowledge has its limitations, seeing Su Li's frowning expression, she thought that he was in a deep thought, in fact, she guessed correctly, Su Li was thinking hard, but he was thinking hard, how could it be more appropriate to play the opponent to death?

"Well, I'll give you a simple question: Now that there are four women, how likely is it that at least two of them have birthdays in the same month?" Su Li said seriously word by word.

Yun Yi was stunned when he heard this: "What do you mean, this possibility can be calculated like a number?" ”

Su Li nodded solemnly. This problem is actually a typical "room division problem" in probability problems. The probability of at least two people in the same room" is actually equal to the probability that at least two people have birthdays in the same month, and the number of events of "at most one person in each room" is: the factorial of N divided by the factorial of (N-n), so that after subtracting the factorial formula from the population of 1, it is easy to get the answer: 0.4271.

After listening to Su Li's spittle explanation, Yun Yi was still at a loss, she just gradually understood such a fact, if you want to compete with Su Li, you must not let him take the initiative! Otherwise, you will definitely lose!

After Yun Yi sat down limply, Su Li smiled proudly, glanced at Yu Lian and Yu Wenxin and said, "Okay, who will come next?" Why don't we all do it together? ”
