Chu Xiangyun sat on the bench outside the empty building, his gaze wandering between the passing senior sister and his student card.

She had observed Zhuqing's student card a long time ago, and the spiritual power structure was no different from her own. So she only had to scan the spiritual power of these people with her eyes to tell if they were carrying student cards.

That being said, there is always no such kind of spiritual power fluctuation in everyone's body. Whenever Chu Xiangyun looked at it, it was more like a ball of intertwined and overlapping threads as far as the eye could see, and she had to pay more attention to it to barely distinguish it, and her eyes began to become sour.

After a while, Chu Xiangyun looked up at the sky, trying to temporarily wash his eyes with the blue sky, and at the same time relax his brain.

According to her rough observations, everyone who entered the Hidden Sky Building did have the spiritual power fluctuations of the student card on their bodies. But when they fused with the shield, Chu Xiangyun couldn't see any specific changes in spiritual power.

She sighed softly.

This is still because of the lack of experience, the spiritual power atmosphere of Ling Xiao Mansion is too strong, but if she doesn't notice it for a while, she can no longer notice the slightest change.

But lamenting here is useless, the most important thing is the present.

Chu Xiangyun turned his gaze back to the pedestrians in front of the Zangkong Building, and silently pondered in his heart. If you think of all of this as an experiment, then the next step in the experiment is to control the variables.

"Do you feel that someone has been watching us...... "A senior sister suddenly felt a chill on her body.

"Shhh Her companion pushed her, his eyes shivering at the man sitting on the bench.

Chu Xiangyun suddenly found that for some reason, the seniors were walking faster, as if they were being chased by something.

She looked curiously into the distance, but found nothing. Chu Xiangyun withdrew his gaze boringly, crossed his hands to support his chin, and made a contemplative posture on the bench.

If all her speculations were true...... Then the people who come to hide the empty building should not forget their "pass". She won't be so lucky, just sit here and wait, and meet a confused senior.

After all, she didn't meet Samia on the road with a rainy umbrella.

It would be nice if someone's student card, like Qi Xiaohong's umbrella, was suddenly lost......

Chu Xiangyun thought so, and suddenly sat up straight with a sudden realization.

It turns out that there is still this trick!

She once again set her eyes on the seniors who were hurrying in their steps.

This spiritual power is very abundant at a glance, it should be a senior senior, and it can't beat it......

This gaze looks very alert and could be spotted......

This one......

Chu Xiangyun finally found a suitable target-

The spiritual power is weak, and he may only be a second-year senior. His eyes were tired, and he may have just stayed up all night last night. The footsteps are floating, and they should have just come out of the training room.

That's you!

Chu Xiangyun took a deep breath and put his student card back in his pocket, but he deliberately showed a side, looking crumbling.

Then she stood up, pretending to be passing by, and passed by the senior.

Syllable!

Their student cards fell to the ground at the same time.

Of course, the senior's one was actually quietly pulled out by Chu Xiangyun.

Chu Xiangyun took the lead in squatting, picked up both cards, and then handed one of them to the senior who didn't seem to react.

"Thank you." The senior nodded in thanks, took the blank student card, and then continued to walk in the direction of the Zangkong Building.

Three, two, one......

Bang!

With the countdown in Chu Xiangyun's heart, the senior, just like her last night, slammed his head into the spiritual power shield of the Hidden Sky Building. The people around him were startled, and the unlucky senior also woke up instantly, and he covered his head and let out a cry of pain in hindsight.

I'm sorry senior......

Chu Xiangyun walked over quickly and handed over the student card in his hand, "Senior, it seems that our card was taken by mistake." Are you okay? ”

"So you're a junior." The senior rubbed his head, straightened up for a long time, and exchanged student cards with Chu Xiangyun, "It's okay, it's all an accident." ”

Chu Xiangyun looked at the senior in front of her and seemed to be very talkative, she pretended to be casual and asked, "Senior, can't first-year freshmen enter the empty building in Tibet?" ”

The senior also lived up to her expectations and replied, "Yes." A student ID card is required to enter the building, and the quests inside are too dangerous for you, so the student ID card of the first-year students does not have access to it. ”

It seems that his conjecture is correct.

Chu Xiangyun nodded, "Thank you, senior, goodbye, senior." ”

After saying goodbye to the person in front of her, she walked back to the bench and fell into a new round of brain storming.

One problem has been solved, and another has arisen.

- How is she going to get a student card for her seniors?

Although she also knows some seniors or seniors, such as You Jingqiao, Lu Qi, Xiaohong, and the like, if she says her purpose, won't she be discovered immediately?

Even if they didn't care about her blatant violation of the school rules, they would definitely be curious about her purpose in wanting to enter the Zangkong Building.

For some reason, Chu Xiangyun didn't want to tell anyone about the empty matter.

There is nothing about the machine spirit in the records of Ling Xiao Mansion, and even the specific information about the Zangkong Mansion is very little. Behind this, there must be a huge secret hidden.

She had an inexplicable intuition: the fewer people who know about this matter, the better.

The easiest way was passed directly, what else could she do next?

Chu Xiangyun frowned in distress, and she looked at the people in front of the Zangkong Tower again, trying to find some inspiration in it.

Suddenly, she saw a man without a school uniform walking straight by, and finally walked into the Tibetan empty building without squinting.

Is that......

Chu Xiangyun's eyes widened slightly, that should be a teacher, right?

By the way, in addition to the students who enter the Tibetan Sky Building, there should also be teachers who issue tasks.

It is more difficult for ordinary people to get a "pass" from a teacher than from a student.

But for Chu Xiangyun, she thought of such a person.

One...... For those who violate the school rules and are happy to see it, will not set foot in the empty building, and have a close relationship with a certain teacher.

Chu Xiangyun took out the map from his pocket, unfolded it, and looked for his destination on it.

- Teacher's Office.

I don't know if the other party is there at the moment, but it's still early, so it's okay to go and take a look.

After she left, a certain senior sister who had entered the Zangkong Building to take over the task quietly poked her head out.

"That junior is finally gone...... I thought she was going to rush over and snatch my student card in the next second. ”

"I can't wait to come over to take on the task when I first enter the school, this class of freshmen is really a bit scary......"
