Chapter 591: what is this?

In the end, he was still not used to calling that "father-in-law" and replaced it with the word "you" to let Nangong Mingchuan come out alone.
No one knew what he was going to do, including Tang Yuyan beside him was also taken aback.
After looking at each other with his wife, Nangong Mingchuan stepped out of the ward and saw Qin Sijue walking not far from the corridor to the left of the ward.
He walked over and didn't feel that he was now Qin Sijue's old man, and he should have some respect for himself. Instead, he was used to Qin Sijue's arrogant and indifferent appearance.
It wasn't until he approached that Qin Sijue took out something similar to a USB flash drive from his pocket.
Nangong Mingchuan must have his eyebrows, staring at the unknown object in his hand, then raised his eyes and looked at him puzzledly, "What is this?"
"The elevator monitoring of this hospital." Looking at him, Qin Sijue still had that cold posture.
Nangong Mingchuan was even more puzzled.
What does the hospital monitor do for him?
Confused, he raised his eyes again to look at Qin Sijue.
"If you want to know how you and your wife fell, follow this clue to check. If you don't want to check, it doesn't matter."
Upon hearing this, Nangong Mingchuan was a little shocked.
What does he mean by this sentence? Does it mean that he and Yu Yan fell down the stairs not an accident, but a premeditated one?
But... is this possible?
After all, no one knew they would take the stairs, right?
He hesitantly took the things in Qin Sijue's hand, his dark eyes still filled with shock and disbelief.
Afterwards, Qin Sijue took out a transparent bag with a pink pearl particle inside.
"And this, should you be familiar with it?" Qin Sijue stared at him.
Nangong Mingchuan looked at the pink beads in the transparent bag again. They were transparent. He probably hadn't seen this thing.
But the moment he saw the beads, a picture flashed in his mind, that was when he was rushing down the stairs that day, he seemed to have stepped on something before rolling down the stairs.
At that time, he didn't think too much, but thought that he was too impatient at the time and accidentally stepped on and slipped and rolled down the stairs.
But now that I think about it, no matter how impatient it is, I will not lose sight of the steps under my feet.
"Where did you find this?" He raised his eyes and asked Qin Sijue.
"On the second floor, down the stairs."
Hearing the answer, Nangong Mingchuan felt more certain.
Sure enough, he stepped on this thing, so he slipped down?
But who is it, and why do you want to do this?
Should this pearl be a necklace? Did someone accidentally fall, so...
"Could it be just an accident?"
"Is it an accident? You can synthesize after watching the video."
After handing the things to Nangong Mingchuan, Qin Sijue did not speak any more, but turned around and took Gu Qiangwei and left.
Nangong Mingchuan was stunned, looking at the two things in his hand, and then at the back of the two people in front of him leaving, he stayed on the spot for an instant, frowning in confusion.
Listening to Qin Sijue's tone, he should have determined that it was not an accident that he and Yuyan fell.
But what he can't figure out is who is going to murder him and his wife...
Looking at the two distant figures, Nangong Mingchuan returned to the ward blindly holding something.
Tang Yuyan, who was standing at the door of the ward, was still waiting for him.
"what happened?"
He raised his eyes and glanced at his wife, "Yuyan."
"Ok?"
"Do you remember why you fell down the stairs?"
