After receiving Pei Xuan's encouragement, Pei Qingyu calmed down.
She nodded to Yu Zhichu and said, "Then let's find a quiet place."
They went to the cafeteria closest to the teaching building, which was as exquisite as a luxury hotel, and chose a private room on the top floor.
It wasn't mealtime yet, so they didn't order any food.
The waiter brought the drinks and then closed the door and left.
"Senior Yu, what do you want to tell me?" Yu Zhichu looked at the door and wall in the box and felt relieved that the sound insulation measures were well done.
She calmed herself down and spoke slowly: "Qingyu, your brother probably hasn't told you that I... am actually his girlfriend."
When these words were spoken, Pei Xuan and Pei Qingyu were both surprised.
Pei Xuan was surprised that Pei Qingye had taken such good confidentiality measures that he didn't even know about his beautiful girlfriend who was as sick as Xi Shi.
But on the other hand, Pei Qingye and Yu Zhichu are both direct descendants of the eight great families. They are forbidden to marry, so it makes sense for them to have a secret relationship.
Pei Qingyu's surprise was more of disbelief. The brother whom she had always respected and loved actually had a girlfriend behind her back. This was like a bolt of thunder.
Although Pei Qingyu knew rationally that her brother had the freedom to fall in love, she still felt completely betrayed.
Her body trembled slightly with anger, and her fingertips secretly pinched the skin on her arms, using the pain to maintain her composure.
"I see." Pei Qingyu bit her lip. "Should I call you sister-in-law?"
"It's a little too late to say this now." Yu Zhichu smiled bitterly, "Qingyu, I just want to tell you about your brother's affairs and ask for closure."
According to Yu Zhichu, she and Pei Qingye were of the same age and grade, had known each other since childhood, and had a good impression of each other, but both of them tacitly did not expose it.
It wasn't until the beginning of this year that things started to move forward.
Unexpectedly, less than four months after they established their relationship, Pei Qingye had an accident.
Before this summer vacation, unusual spiritual energy fluctuations appeared in the Wanmu Mountains. The Imperial College decided to send a team of senior students to investigate the cause as a form of training.
Unexpectedly, a landslide occurred and Pei Qingye died under the rocks in order to protect other team members.
"This jade pendant is a token of love your brother gave me." Yu Zhichu took out a jade pendant with an ancient shape from his arms, "Now, I will return it to you."
Pei Qingyu stretched out her trembling hand to take the jade pendant and held it tightly in her palm. The temperature of the jade pendant seemed to be so hot that it could burn a hole in her palm.
Pei Qingyu recognized the jade pendant because she had an identical one herself.
The two jade pendants were originally a pair and were the only souvenirs their biological mother Du Ruoyun left for them before she returned to her parents' home.
Pei Qingyu had always treasured his jade pendant because it was a pair with Pei Qingye's, but he had never expected that Pei Qingye had already given it to someone else.
"Then... Senior Qi Yang..." Pei Qingyu's voice was trembling with endless sadness and anger. "You and Senior Yu came to see me together. Do you have something to say?"
"I'm here... to comfort Zhichu." Qi Yang's face was a little embarrassed. "But your brother and I participated in that training together. If you have any questions about the accident, you can ask me. I can answer them for you and let you know the specific circumstances of the accident."
"Thank you." Pei Qingyu closed her eyes and forced back the tears that were about to flow out. "I don't want to know too much."
"I want to know." Pei Xuan, who had been silent all this time, suddenly interrupted, "Can I ask?"
As a member of the aristocratic circle, Qi Yang naturally knew Pei Xuan's identity. He only had contempt for Pei Xuan, the illegitimate child, and was puzzled by the intimacy between Pei Qingyu and Pei Xuan.
He glanced at Pei Qingyu, and seeing that she had no objection, he agreed: "Okay."
"Did you have physical contact with... my brother within ten minutes of his death?"
Qi Yang's eyelids twitched: "No."
"I understand." Pei Xuan winked at Pei Qingyu, then stood up and said, "Sorry, I have to go to the bathroom. Excuse me."
Although Pei Qingyu was in a very bad mood, he still understood Pei Xuan's meaning. He also used the excuse of going to the bathroom and followed Pei Xuan out of the box.
"What's wrong?" Pei Qingyu asked in a low voice when they reached a secluded place.
Pei Xuan looked around and confirmed that there were no strangers or surveillance cameras. Then he whispered, "Your brother's death is related to Qi Yang."
"What?" Pei Qingyu was so heartbroken that she was stunned for a moment before realizing what Pei Xuan meant. "How did you know?"
Pei Xuan couldn't answer because he knew the information from the inquiry system.
The system has a know-it-all function, but it can only answer objective facts of a low level.
Pei Xuan hasn't used it for a long time because it's really troublesome to find the right way to ask questions.
But today Pei Xuan urgently activated this function because he had a bold idea.
This idea originated from Qi Yang's attitude. Although Qi Yang disguised himself well, Pei Xuan could still easily see that he was interested in Yu Zhichu.
Later, when Qi Yang said that he was present when Pei Qingye died, Pei Xuan immediately wondered if Qi Yang had killed Pei Qingye in order to get Yu Zhichu?
At that time, Pei Xuan immediately and silently asked the system whether Pei Qingye had any physical contact with Qi Yang within ten minutes before his death, and the system gave an affirmative answer.
This alone does not prove anything.
But when Pei Xuan asked Qi Yang about this matter, Qi Yang lied, which showed that he was guilty.
Although Pei Xuan didn't know the specific method, there was no doubt that Qi Yang directly caused Pei Qingye's death.
"I can't tell you the reason, but I just know it. You have to believe me." Pei Xuan said to Pei Qingyu, "As long as you cooperate, I have a way to prove it."
Pei Qingyu agreed without hesitation. She didn't believe Pei Xuan's motives, but she believed in Pei Xuan's abilities.
Pei Xuan immediately activated the invisibility spell and grabbed Pei Qingyu's hand, making her disappear with him.
Pei Qingyu immediately understood Pei Xuan's plan, and the two of them returned to the box tacitly, moving gently and trying not to make any noise.
They came behind the seats of Qi Yang and Yu Zhichu. Pei Qingyu took out a fine needle, quickly cut open the tip of Qi Yang's little finger and took blood. After hesitating for a second, he took Yu Zhichu's blood.
Qi Yang and Yu Zhichu suddenly felt a sharp pain in their fingers, as if they had been stung by a bee, and a little blood oozed out.
Although it was puzzling, I didn't take it too seriously.
