"It should be my little friend left, so I feel sad all of a sudden. Now my mood should be stable. I think I will go back to my room to sleep in a few days." Qin Lianyi said.

"I think so."

While they were talking, a servant on the other side of the stairs on the second floor exclaimed.

Qin Lianyi looked up and said, "what's the matter?"

The servant said, "I don't know what hit a small hole in the wall behind this vase."

Qin Lianyi and Ling still have a look at each other, so they go up the stairs and come to the little hole that the servant said.

It was a small hole that seemed to be shot by something. Before, there was a big vase in this position. There were some green plants on the vase. Those green plants just covered the hole, so now I found it.

Ling still squatted down and looked at the green plants. Sure enough, he found that there was a hole on one of the green leaves, which matched the size of the hole on the wall.

"What's going on?" Qin Lianyi asked, "how can there be such a hole? Who was in charge of cleaning before? "

"I've been in charge of cleaning, but this vase is usually just cleaned. It's usually about half a month before it is completely removed and the dust against the wall is thoroughly cleaned." The servant said hastily, "last time... I didn't have this hole."

Ling still looks at the hole, full of doubt. After a moment, he says to Qin Lianyi, "Lianyi, let someone call the police. I think the police may come here."

"Well? The police? " Qin Lianyi was startled and called the police according to what her friend said.

When the police came, they took out an air gun bullet stuck on the wall from the scene. Although the bullet hit the body, it would not kill people, but it would hurt people.

If you hit some positions, you may even be disabled for life.

Qin Lianyi's body trembled and her face turned white. "How could there be such a warhead? Who did it? If someone passes by and is hit, isn't it...

at this point, Qin Lianyi suddenly seems to think of something and turns to look at Ling.

And Ling's expression, also seems to think of something, the same looking at Qin Lianyi, "is that day, Xiaofei because of the sound of the air gun bullet, so will push away Xiaoyan?"

"It's very possible that Xiaoyan didn't hear the sound, but Xiaofei heard it." Qin Lianyi guesses.

Ling still took a deep breath and said to the police, "I hope the police can do an experiment here, so that maybe we can know when the bullet appeared in this room, which may be more helpful for the police to catch the prisoner."

If the result of this experiment is really as she thought, then all of them... Really misunderstood Xiaofei.

Xiaofei saved Xiaoyan, not Xiaoyan.

Thinking of the grievances and wrongs Xiaofei suffered before, Ling still felt a pain in his heart.
