What will be the consequences of abandoning the "six-foot Qiongyu", Ojiaou knows better than anyone.

Li Zheng once mentioned to her that the current Aojiaou is completely relying on this contract to hang her life, if she is too far away from the "six-foot Qiong Hook Jade", then she will soon die due to the exhaustion of her soul.

However, at this time, Aojiaou did not hesitate at all to make this act, as if he was not giving up something that was closely related to his life.

["You said you saved me last time, so this time I ...... replace"]

Even Li Zheng, who had been smiling at everything all the time, felt Aojiaou's extremely enthusiastic thoughts at this time.

["That, Tsundere, it's useless if you lose the 'Six-Foot Qiongyu'. I signed a contract for you, not with the 'six-foot Qiong Hook Jade', that thing can only be regarded as a house......"]

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

"Why aren't you leaving?!" Don't you notice that the one on the other side is called Patchouli Norreji ...... already ]

["Shhhh

["Good...... Aojiaou looked back, only to find that Pachouli had conjured a light whip at this time, entangled the "Six-foot Qiong Hook Jade" that was being taken away by the "Secret Spy Equipment and Drone".

Ojiaou looked back at Li Zheng beside him, and found that he didn't move at all - it was clear that even if the "Six-Foot Qiong Hook Jade" was tied, it was not he who suffered.

As soon as Patchouli withdrew her hand, the "Six-Foot Qiong Hook Jade" was pulled back, and then she looked at this small spirit weapon and asked, "Is it Li Zheng?"

"That...... If I say I'm not, will you beat me up for being too disappointed?"

Little Lori's voice came from the "Six-Foot Qiong Hook Jade", and then under the further questioning of the Fudo Great Library in Gensokyo, a wide forehead undead little Lori who was wrapped in a light whip came out of the "Six-foot Qiong Hook Jade", and said to Patchouli with an innocent face, "Look, there is really nothing here, only me......

"Are you...... I remember seeing you a few times in Yukino's deck, but you didn't see me. Patchouli stared at the "gray Liuli" 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, just the same rhetoric she had prepared earlier, "So can you please let me out first, this whip is a little tight." ”

"......" Patchouli glanced at Ulala in front of her, blinked, and carefully observed the "Six-Foot Qiong Hook Jade", and found that there were indeed no other spirits in it before letting go of the little Lori.

"Whew...... Almost suffocated. After untying the rope that bound Ulala, she first spat into the sky, and then pointed to herself and said, "Oh no, I'm an undead, I won't be held back at all~"

"Don't interrupt. Patchouli even stopped "Gray Liuli" from changing the subject: "You haven't said why you're here." ”

At this time, Ao Jiaou also came over, she looked at the "Gray Liuli" who was performing hard, and she already knew Li Zheng's thoughts in her heart.

He wanted "Gray Liuli" to take his place, so that Patchouli mistakenly thought that the mysterious spirit next to Aojiao was "Duel Elf Gray Liuli" instead of "Behind the Spirit".

"It's easy to say. Patchouli looked at the "Gray Flow" in front of her, clearly disbelieving her words, "You don't look like you can easily open the door outside. ”

After "......" knew what Pachouli meant by "the door outside", Ulala knew that at this time, the other party was actually saying "You look stupid" in disguise, so Ulala's little Lori's wide forehead squeezed out a lot of "#" characters.

Then she said angrily: "Don't underestimate me! I am a genius girl who has gone through three lifetimes - the experience and knowledge of the three generations as a genius have been accumulated in my head, and opening a door or something is as easy as drinking a drink!"

Li Zheng: ["Hey, hey, there is no such sentence in the 'outline' you just gave me!"]

Ulala: ["No Road, it's a matter of dignity!"]

"Oh, really? So...... How about you answer me a few questions and prove your true identity?" After listening to Ulala's explanation, Patchouli still didn't seem to believe it, and coldly opened her mouth to ask "Gray Liuli" to answer a few questions first: "Don't worry, if you are really powerful enough to slap open the 'doppelganger of the door of truth' that I can only push slowly, then these questions should not be difficult for you." ”

["What?''Truth Gate doppelganger'?!How do you feel as if you've accidentally provoked the big guy......"] Even if Ulala really doesn't understand anything, she should know how awesome the door that was swept open by Li Zheng's door just now after hearing this name.

But what's more troublesome now is that Pachouli obviously has to ask a few questions that are in line with her current identity as a "genius of the third world", ["Hey, hey, hey, this is different from what she said......"]

Obviously, in the face of the upcoming assessment, Ulala was instantly stunned.

["Calm down, I'll answer any questions. Li Zheng said to "Gray Liuli" with a calm face: ["How could I not have thought that Patchouli would test you. ”】

With Li Zheng's assurance, Ulala was much more relieved: ["Okay...... However, I think this magic is in a very bad mood right now, so I guess it will make things difficult for us later. ”】

"Rest assured. Li Zheng touched his head and comforted Ulala, and then Pache began to ask questions.

"First question. Patchouli thought for a while and then said, "There is a time difference between world A and world B, and after a day of world A, world B will only pass for one minute, and the rest of the conditions of the two worlds are all the same, so how many times is the total amount of three entropy in world B compared to world A?"

Gray Liuli: "......"

Ojiaou: "......"

Whether it is Ulala or Ojiaou, there is only one sentence in their heads at this moment, and that is "why I understand every word you say, but I can't understand the combination".

["Three, two, and fifty. ”】

Just when Urala's face was embarrassed, Li Zheng's voice reached her ears in time - at this time, in the heart of "Gray Liuli", the voice of Ling Li Zheng, who originally listened to and felt disturbed, was now like Xianle.

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

"Is the total amount of matter three times, the total amount of energy twice as much, and the total amount of information fifty times as much?" After hearing this answer, Patchouli automatically finished Li Zheng's words, and then she frowned and nodded: "This model is valid, but next time I still hope you can give a formula, don't always think about setting special values...... Then the next question. ”

"Phew......" Ulala and Ojiao breathed a sigh of relief when they heard Pacully's reply, and then continued to prick up their ears to listen to Pache Teaule's questions.

"Question 2. Patchouli continued to say with a blank face, "Please briefly discuss why in a world where youkai have lost their power, why can you keep your power by enclosing a small number of humans with an enchantment and letting them continue to fear youkai?"

["Is there such a world?"] This question is much more accessible than the previous abstract questions of "world A" and "world B", at least Ulala and Aojiaou have been in contact with "monsters", but they have never been in contact with a world like this in the experience of "Gray Liuli" for several lifetimes, so this question ...... She still couldn't get there.

But Aojiaou still wants 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, the answer to this question can be guessed: "Hmm...... Relying on the power of will......"

["The effect of information echo to energy, the function of the barrier is mainly to ensure that the information within the barrier does not flow out excessively, and it can also isolate the entry of information from the outside world. Before the answer of "Gray Liuli" could be spoken, Li Zheng interrupted her in time, and it was the same as before, only this short sentence of pinching the head and the end.

This made Ulala and Aojiaou very puzzled, and Aojiaou also asked Li Zheng with his years of exam experience: ["That, if you want to write an essay question, you shouldn't write as many ...... as possible"]

["Short-answer questions and essay questions actually only look at the key points, and in most cases, writing a lot of words is just to cover up that you don't remember the key points clearly. Although Li Zheng covered his mouth with a snake scale fan, Ojiaou and Ulala could still feel the banter in his tone, ["Anyway, you should answer quickly, you won't be able to remember it after I tell you everything." ”】

......Although she was a little unconvinced, this was indeed the fact that "Gray Liuli" would face now, and she had no more choice, so she had to throw out the answer given by Li Zheng.

After hearing Gray Liuli's answer, Patchouli's brow tightened, and finally she nodded and said, "The answer is correct, and it's too fast............ Some, too fast......"

Ulala's wide forehead was now covered with cold sweat, but now she could only force her composure and say, "Ahem, yes, so, I said that I was a genius girl reincarnated in the third life, this question ...... something"

"This is a problem that a certain 'monster sage' with thousands of years of experience has been thinking about for a long time before coming up with a solution. Looking at Ulala, who was acting forcefully, Patchouli said teasingly: "You solved it so quickly...... Otherwise, I'll take you to seal some 'sage' next time?"

“......”

Ulala was sweating profusely and said embarrassedly, "That...... Next time, next time. ”

"The third and final question. Pache stared at the "gray Liuli" spirit, as if she wanted to see through the spirit of the undead little Lori who was in an extremely embarrassed state, so as to discover the secret behind her: "There was a time-traveler who went back in time, and then someone grabbed his unmarried grandfather and five other people. The other party tied the traverser's grandfather to the abandoned train tracks, and tied the other five people to the train tracks in use. Then the train comes, and the traverser has a button in his hand to change the running track of the train...... So is there any chance that the traverser will press this button and save those five people?"

"......" Pache Paciuli's third question once again puts "Gray Liuli" and Okao into a state of confusion - anyone with a discerning eye can see that this problem should be a variant of the "tram problem", which makes the already tangled "tram problem" even more tangled.

But Aojiaou still said: [Do we really have to understand so many things to learn to play cards?]

Of course, this question is much better than the previous two—because outsiders can at least understand it and think about it.

And "Gray Liuli" was about to say "he couldn't press that button" after thinking carefully, but was interrupted by Li Zheng again.

["You told her that the conditions were not enough, and refused to answer. ”】

Gray Liuli's eyes widened, "This...... Won't that reveal the stuffing?"]

["You tell your answer before it's really exposed."] Li Zheng shrugged, then thought for a while and said to Gray Liuli: "If Patchouli asks you why the conditions are insufficient, you will say that you didn't say 'true sexual crossing' or 'fake sexual crossing'. ”】

["Uh...... Good, good. Ulala, who had no more ideas for the time being, had to say this.

"Interesting......" After listening to Gray Liuli's answer, the corners of Pache Li's mouth curved in an arc that no one else could know, and then ......

"Yes, I believe in you, Li Zheng is not here. ”

What Aojiaou and Ulala didn't expect was that after a little thought, Patchouli actually let go of the person and spirit in front of her, and at the same time returned the "six-foot Qiong Hook Jade" to Aojiaou.

Before he could react, Ao Jiaou, who had not yet reacted to why this was okay, took the "six-foot Qiong Hook Jade" with a confused face.

"From today onwards, I will be your mentor, tell Shark Island, you have passed. Patchouli looked at Ojiao in front of her with unadulterated eyes, "Remember to lock the door when you leave the library. By the way, as a mental compensation for scaring you today, this card you hold should be useful. ”

"Oh...... Oh......" Aojiaou took the "Gate of the Six Martial Arts" handed over by Pachouli in a daze, but he still couldn't understand why she was acting like a tiger?

Before he could figure out why Pache had such a big change in his reaction, Ogao walked out of the library in a daze—by the way, by the way, when he went out, "Gray Liuli" personally tried to see if he could push open the "doppelganger of the door of truth", but of course he didn't move.

This made a "genius girl with three lifetime experiences" very dissatisfied, and felt as if she was despised by a door.
