Gently rubbing his hands, Gu Yibei asked with concern: "Does it hurt?"

The movements are so natural.

Ji Zhinan lowered his head and stared blankly at the man's short dark hair, lost in thought for a moment.

Without getting a reply from Ji Zhinan, Gu Yibei looked up into her distraught eyes and asked, "What's wrong?"

Ji Zhinan suddenly came back to his senses and immediately shook his head at him: "It's okay."

Gu Yibei carefully checked Ji Zhinan's ankle again, and only stood up after making sure there was no sign of swelling.

Seeing her fall at the stairs just now really scared him to death.

This is the second floor. It’s not very high, but falling down the stairs would definitely not result in a minor injury.

Fortunately, no one is hurt.

There was quite a commotion here. Principal Zhang ran out when he heard the noise. Seeing the two people at the stairs, he asked with concern, "What happened?"

Gu Yibei replied calmly, "It's okay, I just slipped."

Upon hearing this, Principal Zhang saw the cleaning lady mopping the floor on the first floor and scolded her with a stern face, "Auntie Yang, make sure you mop up all the water on the floor when you mop. What if someone falls?"

Aunt Yang, who was working, was stunned when she heard this. She looked up at the somewhat angry Principal Zhang on the second floor and replied blankly: "Principal Zhang, I haven't mopped the second floor yet."

"What?" Principal Zhang was also dumbfounded.

Ji Zhinan walked to the stairs and squatted down, staring at the first step with cold eyes. The steps were somewhat reflective under the light.

There was undoubtedly something on the steps.

She wiped her fingers on the steps, and Ji Zhinan stared at her fingertips, which were wet.

After careful consideration, I found that it was not water, but more like... oil.

Ji Zhinan grinned. It seemed that someone was waiting for her here.

The stairs here lead directly to the second floor only, and on the second floor there are only a few meeting rooms and Principal Zhang's office.

It is unlikely that someone deliberately poured oil to retaliate against Principal Zhang. Principal Zhang has been diligent and friendly over the years and is not the type to hold grudges against others.

Then the only ones who could be targeted would be Gu Yibei and I who came to visit Principal Zhang today.

Gu Yibei was not a student of A University before, and he came here only to donate experimental equipment on behalf of Lin Que. Apart from Principal Zhang, the only person who knew him in the whole school was probably Ji Zhinan.

Therefore, it can only be directed at oneself.

The smile on Ji Zhinan's face grew wider and wider, which made Principal Zhang's heart tremble and he felt inexplicably scared.

In fact, he also discovered that Ji Zhinan seemed to be possessed by a ghost and suddenly became a different person.

She used to be smart and elegant, like a gentle lily, introverted and low-key.

Now she is still as smart and beautiful as before, but she is no longer a lily. Instead, she is that beautiful red rose, as scorching as the sun. She is less shy and more bold and arrogant.

Aunt Yang, the cleaning lady, also came up and stopped five or six steps away from the second floor. She looked carefully at the thing on the steps and said, "Principal Zhang, this is not water, it's oil!"

And there were smudges on five or six steps in a row. The oil was scraped very evenly, not just in a puddle. If you didn't look carefully, it looked like the floor had just been mopped and wasn't dry yet.

"Oil?"

Upon hearing this word, Principal Zhang frowned and squatted down to verify.

It’s really oily.

He stood up suddenly, furious: "This is an office building, not a cafeteria. How can there be oil in the administration building!"
