Ojiao knows better than anyone what the consequences of abandoning the "Six-foot Magatama" will be.

Li Zheng once mentioned to her that Ojiao's life depends entirely on this contract. If she is too far away from the "Six-foot Magatama", she will soon die due to the exhaustion of her soul.

However, at this time, Ojiao did this behavior without any hesitation, as if he was abandoning something that was not closely related to his life.

["You said you saved me last time, so let me do it this time..."]

Even Li Zheng, who had always looked at everything with a smile, felt Ojiao's extremely enthusiastic thoughts at this time.

["Well, Tsundere Ou, it's useless if you lose the 'Six-foot Magatama'. I signed the contract for you, not with the 'Six-foot Magatama'. That thing can only count as a house..."

…”]

So Li Zheng chose to speak in the girl's ear immediately, shocking her.

["You! Why don't you leave?! Haven't you noticed that the person opposite named Patchouli Noreki has..."]

["Shh!"] Li Zheng interrupted Ojiao's message in time, pointed to the front and said: "Don't worry, I have been ready since the first time I saw her. Just wait.

Let’s watch the show~”]

["Good... play?"] Ojiao looked back and realized that Patchouli had already transformed a light whip and was taking away the girl who was being taken away by the "Spyry Equipment Drone".

The "Six-Foot Magatama" is entangled.

Ojiao looked back at Li Zheng beside him and found that there was no movement from him at all - obviously, even if the "Six-foot Qiong Magatama" was tied up, he was not the one who suffered.

As soon as Patchouli stopped her hand, the "Six-foot Magatama" was pulled back. Then she looked at this small spiritual weapon and asked, "Is it Li Zheng?"

"Um...if I say I'm not, will you beat me up because you're too disappointed?"

The little loli's voice came from the "Six-foot Magatama", and then under further questioning at the Fudo Library in Gensokyo, a wide-foreheaded undead little loli wrapped in a light whip came out of the "Six-foot Magatama".

"Qiong Magatama" emerged from the middle, and said to Patchouli innocently, "Look, there is really nothing here, only me..."

"You are... I remember I saw you a few times in Yukino's deck, but you have never seen me." Patchouli stared at the "Gray Flow Rei" in front of her and said, "Why are you here?"

"Why am I here? Well, that's a good question." Ulala said that the question was too timely, and it happened to be the rhetoric she had prepared before, "So can you let me out first, this whip is tied

It has to be a little tight.”

"..." Paqiuli glanced at Ulala in front of her, blinked, and carefully observed the "Six-foot Magatama". She found that there was indeed no other spirit body inside, and then she let the little Loli go.

"Huh... I almost suffocated to death." After the rope that tied Ulala was untied, she first breathed into the sky, then pointed at herself and said: "Oh no, I am an undead, I will not be suffocated at all.

Coming~"

"Don't interrupt." Even though Patchouli stopped "Hui Liuli" from changing the subject, "You haven't said why you are here yet."

At this time, Aojiao also came over. Looking at "Hui Liuli" who was performing her best, she already had a rough idea of ​​what Li Zheng was thinking.

He wanted "Hui Liuli" to take his place, making Patchouli mistakenly think that the mysterious spirit next to Ojiao was "Duel Elf Hui Liuli" rather than "the spirit behind Li Zheng".

"That's easy to say." Patchouli looked at the "Hui Liuli" in front of her and said she obviously didn't believe her words. "You don't look like you can easily open the door outside."

"..." After knowing what Patchouli meant by "the door outside", Ulala knew that the other party's words at this time were actually saying "you look stupid" in disguise, so Ulala

There are a lot of "#" characters squeezed out on the little Loli's wide forehead.

Then she said angrily: "Don't underestimate me! I am a genius girl who has lived through three lives - all the experience and knowledge of being a genius in three lives have been accumulated in my head. I can open a door or something, and drink."

Drinks are just as easy!”

Li Zheng: ["Hey, hey, hey, this sentence is not in the 'outline' you just gave me!"]

Ulala: ["No road race! This is a matter of dignity!"]

"Oh, really? Then... how about you answer me a few questions and prove your true identity?" After listening to Ulala's explanation, Patchouli still didn't believe it, and said coldly, trying to "Grey"

"Liu Li" will answer a few questions first: "Don't worry, if you are really powerful enough to slap open the 'Clone of the Door of Truth' that I can only push slowly, then these questions

It shouldn't be difficult for you."

["What? 'The clone of the Gate of Truth'?! Why does it feel like I accidentally offended the boss..."] After hearing this, even if Ulala really doesn't understand anything, she should know what she just heard after hearing this name.

The door that was swept open by Li Zheng's fan was so awesome.

But what's even more troublesome now is that Patchouli obviously wants to ask a few questions that fit her current role as "The Third Genius", ["Hey, hey, hey! This is different from what was promised..."]

Obviously, facing the upcoming assessment, Ulala was instantly frightened.

["Calm down, I'll answer any questions."] Li Zheng said to "Hui Liuli" calmly: ""How could I not have thought that Patchouli would test you."]

With Li Zheng's guarantee, Ulala felt much more at ease: ["Okay...but I think this magician is in a bad mood right now, so he will probably make things difficult for us later."]

["Don't worry."] Li Zheng touched his head and comforted Ulala, and then Patchouli began to ask questions.

"The first question." Patchouli thought for a while and then said: "There is a time difference between world A and world B. After one day has passed in world A, only one minute has passed in world B. The other conditions of the two worlds are the same.

, then may I ask how many times the total amount of three entropies of world B is that of world A?"

Hui Liuli: "..."

Ojiao: "..."

Whether it was Ulala or Ojiao, there was only one sentence in their heads at this moment, and that was "Why do I understand every word you say, but I can't understand it when they are put together?"

【"Three, two and fifty."】

Just when Ulala looked embarrassed, Li Zheng's voice reached her ears in time - at this time, in the heart of "Hui Liuli", the voice of Li Zheng behind her that was so disturbing at first was now simply...

Like celestial music.

Although she didn't understand what Li Zheng said, she still read it.

"Three times the total amount of matter, twice the total amount of energy, and fifty times the total amount of information?" After hearing this answer, Patchouli automatically completed Li Zheng's words, then she frowned and nodded:

"This model is established, but next time I hope you can give me a formula instead of always thinking about setting special values... Then the next question."

"Huh..." Ulala and Ojiao breathed a sigh of relief after hearing Patqiuli's reply, and then continued to listen to the questions that Patqiuli would ask.

"Second question." Patchouli continued to say expressionlessly: "Please briefly explain why in a world where monsters have lost their power, why a small number of humans are surrounded by barriers so that they continue to be afraid of monsters.

Can the monster continue to maintain its power?"

["Eh? Is there such a world?"] Compared with the previous abstract question of "World A" and "World B", this question seems to be much closer to the people, at least both Ulala and Ojiao

She has come into contact with "monsters", but in the several lifetime experiences of "Hui Liuli", she has never been exposed to a world like this, so this question... she still can't answer it.

But Ojiao still wanted to complain: [Do you need to know so many things to learn to play cards?]

Of course, unlike the previous question, which I didn't understand at all, Ulala can at least guess the answer to this question: "Well... it depends on the power of will..."

["Information echo turns into energy effect. The main function of the barrier is to ensure that the information within the barrier does not flow out excessively, and it can also block the entry of outside information."] Li Zheng responded in time before "Hui Liuli" could say his answer.

The sound interrupted her, and it was still the same as before, with only this short sentence that was cut off from the beginning to the end.

This puzzled both Ulala and Ojiao. Ojiao also used his many years of examination experience to ask Li Zheng: "Well, for essay questions, you shouldn't write as much as possible..."]

["Short answer questions and essay questions actually only look at key points. Writing a lot of words is mostly just to cover up that you have not remembered the key points clearly."] Although Li Zheng covered his mouth with a snake scale fan, Aojia

Ou and Ulala could still feel the joking in his tone, ["Anyway, answer quickly, you won't be able to remember it all after I tell you everything."]

["..."] Although she is a little unconvinced, this is indeed the fact that "Hui Liuli" will face now, and she has no more choice but to throw out the answer given by Li Zheng.

"..." After hearing "Hui Liuli"'s answer, Patchouli's brows furrowed even more tightly. Finally, she nodded and said: "The answer is correct, and it's too fast... Some are too fast..."

"

[It's over, it's over! It's going to be seen! It's going to be exposed!] Ulala's broad forehead is now covered with cold sweat, but now she can only force herself to say calmly: "Ahem! So, I said I am

A genius girl reincarnated in three generations, this question and so on..."

"This problem was something that a certain 'monster sage' with thousands of years of experience thought about for a long time before he came up with a solution." Looking at Ulala's serious performance, Patchouli said jokingly: "You solved it so quickly.

Oh...how about I take you to try to become a 'sage' next time?"

"..."

Ulala was sweating profusely and said awkwardly: "Well... next time, next time."

"The third and final question." Patchouli stared at the spirit body of "Hui Liuli", as if she wanted to penetrate the spirit body of this little undead loli who was in an extremely embarrassing state, so as to find out what was behind her.

The general secret: "A time traveler went back to the past, and then someone captured his unmarried grandfather and five other people.

Live. The other party tied the time traveler’s grandfather to the abandoned train tracks, and tied the other five people to the in-use train tracks. Then the train came, and the time traveler had a button in his hand that could change the track of the train... So, please ask

Is it possible for the time traveler to press this button and save those five people?"

"..." Paqiuli's third question once again put "Hui Liuli" and Aojiao into a state of confusion - anyone with a discerning eye can see that this question should be a variant of the "tram problem", turning the original question into a state of confusion.

The troubling "tram problem" becomes even more tangled.

But Ojiao still said the same thing: [Do we really need to know so many things to learn how to play cards?]

Of course, this question is much better than the previous two - because outsiders can at least understand it and can have some thoughts on it.

After thinking carefully, "Hui Liuli" was about to say "He can't press that button" when he was interrupted again by Li Zheng.

["Tell her that the conditions are insufficient and refuse to answer."]

["Eh??"] Hui Liuli's eyes widened, ["This...won't this reveal the truth?"]

["You really revealed your answer when you said it."] Li Zheng shrugged, then thought for a while and said to Hui Liuli: "If Patchouli asked you why the conditions are not enough, you just said you didn't say yes."
To be continued...
