Mu Tianyu knocked on the door and came in. When she saw this spectacle, she looked around and first looked for her younger sister, who was bored and stood at the side obediently, looking down at her toes.

Perhaps it was because she heard her come in, she looked up and smiled sweetly at her without any fear at all.

Mu Tianyu immediately felt relieved. Although she did not hear anything strange about her on the phone and knew that she was asked to call her parents, she could not help but worry.

Now after calming down, she thought about it and guessed that something had happened. She turned her gaze and met a pair of eyes with gold-rimmed glasses. The lenses were a little reflective. She could not see the true emotions in the other person's eyes, but the corners of the man's mouth curled up.

Mu Tianyu was not interested in continuing to size him up. She turned her gaze away once again and looked at Song Ling with a hint of respect, "Principal, long time no see."

"Ah Yu, long time no see." Song Ling's solemn square face softened a little.

"My parents and brothers are out, so I am the representative. So why does my sister need to call her parents?" Mu Tianyu asked.

That delicate oval face was cold and severe, and a pair of peach blossom eyes were clear and the gaze was light, but the momentum was not low at all. It was not intentional, but innate.

Of course, Song Ling would not say it himself. He did not even have the ability to say that he could win against Mu Tianyu. Moreover, the one who caused the trouble should say it. "Director Qin, tell me the ins and outs of the matter."

When the dean heard this, he immediately felt the pressure of being stared at. He did not dare to look Mu Tianyu in the eye. Back then, he had failed in the debate with her in the law course where he was the teacher.

Not to mention now, he could only explain things stutteringly.

Mu Tianyu was not surprised to hear that. "So Director Qin, you are slandering my sister in a situation where you have no actual evidence. According to the laws of Country A, the highest punishment for defamation is a fine of $7000 and imprisonment for a year. And in serious cases, you would be imprisoned for five years."

Mu Tianyu's voice wasn't very loud, and it was even quite pleasant to hear, but it sounded like thunder exploded in the ears of the dean and the teachers.

When they didn't believe Mu Tianen could get such good results, they hadn't thought Mu Tianyu would be called over.

They were looking for trouble.

"Also, Director Lin, your suggestion is complete nonsense. If you raise a complaint, you have to find evidence to prove it, instead of asking my sister to prove her innocence and letting her retake the exam alone. Do you think it's like watching a monkey show? You can ask her to do it as often as you want?"

Suddenly, the imposing aura that the prominent families cultivated burst out from Mu Tianyu and enveloped the entire office. The hearts of the teachers present could not help but tremble, and an overwhelming pressure attacked them.

The second-grade director hurriedly revealed an embarrassed and fawning smile, "My suggestions are too ill-considered."

After he finished speaking, he took two steps back to avoid being attacked by Mu Tianyu again. He could not afford to provoke her, but he can hide from her.

The third-grade director and Song Ling were enjoying the show.

Knowing that her sister had come, Mu Tianen felt more at ease. She lowered her head and continued to play with herself. It was because her sister's voice was a little too loud, she looked up curiously.

She secretly exclaimed in her heart. She had wasted so much saliva just now and still couldn't make it clear. Her sister was still the best. She had a lot to learn from her sister.

On the other hand, Jin Yi was quite surprised. Just now, when Mu Tianyu came in wearing white professional pants, although the aura was strong, she did not lose her nobility. He did not expect her mouth was even more stunning.

That oval face with red lips and white teeth clearly did not have the slightest bit of aggressivity. Her expression was a bit cold and arrogant. Her peach blossom eyes were light and clear, revealing an extreme indifference. It seemed that it was very difficult for something to attract her attention.

Jin Yi thought that Mu Tianyu would ask his Seventh Junior Sister about this matter. After all, her appearance gave him the feeling that she cared about the reputation of her family.

But she completely believed her sister without a trace of doubt, and then her red lips that were as smooth as flower petals began to speak words that made people unable to counterattack at all.

"Now, can I take a look at the surveillance of my sister's exams?" Mu Tianyu looked around and saw that no one was refuting her.

"Yes," Song Ling said.

Then the third-grade dean took the initiative to contact the security department and asked them to bring the surveillance video over.

"Since you want us to find the evidence ourselves, I will give you the evidence to prove her innocence," Mu Tianyu said indifferently.

This was a slap to the faces of the teachers who were aggressive towards Mu Tianen.

Soon, the surveillance videos were brought over. Mu Tianyu looked at the surveillance videos for her sister's examinations. "Haili University's surveillance system can be said to be the best among all the universities in the country. This can't be faked. Do the teachers here have any objections?"

"No."

Those teachers who had been refuted did not dare to have any objections.

"Then Teacher Wang, Teacher Zhou..." Mu Tianyu called out one by one, "You have been teaching for many years, and you guys have proctored at least dozens of tests. Couldn't you see whether a student cheated on the spot?"

Mu Tianyu's sharp gaze fell on the teachers again. They lowered their heads in embarrassment, not daring to meet her gaze.

"Alright, since she didn't cheat on the spot, then you guys possibly would say that the exam questions were leaked in advance." Mu Tianyu asked respectfully as her sharp eyes fell on Song Ling, "Principal Song, how about you answer this question?"

Song Ling stood up with a serious face and a righteous look on his face, "I am very responsible to tell everyone that before this midterm exam, there is no possibility of the exam questions being leaked in advance, because the exam questions for each subject are written one hour before the exam, and then they are printed in large quantities and then immediately sent into the exam room."

All the teachers who doubted Mu Tianen's results did not refute him.

Every time there was a large exam at Haili University, it would close the school gate and turn off the signal an hour in advance so that the students could study peacefully until the last second. Even if Mu Tianen had the ability to get the answer to the exam in advance, she would not be able to bring it to the school.

An hour before the exam, no one could get close to Haili University, and the supervising teacher was only temporarily arranged twenty minutes before the exam.

Even if a teacher wanted to help, he couldn't, because all the teachers had to wait in the office before the examination.

"So Mu Tianen relied on her ability to score excellent results," Song Ling said sternly.

Mu Tianyu walked to her sister's side and pulled her out. He slightly raised her chin and her gaze sank. "Teachers, let's meet in court."

When Jin Yi heard this, a smile flashed across his eyes which were covered by gold-framed glasses. "So resolute." He thought.

All of a sudden, the teachers panicked. They did not know much about Mu Tianyu, but there was one thing that everyone who knew her knew. It was that what she said was never false, and she kept her word.

Mu Tianyu was famous for her being a never-fail General throughout Haili University. Even the new teachers knew how powerful she was. There weren't many lawyers in Nanyang City who dared to fight against her, but they couldn't afford to hire those lawyers who dare to fight against her.

The second-grade dean, who had retreated to the wall, felt a wave of lingering fear. He felt fortunate about not doing anything else.

As for the third-year dean, he saw that his colleague's expression had changed. A sneer appeared in his eyes. These people had always relied on their status as teachers of Haili University to think that they were superior. Today, they had hit an iron plate.

He knew Mu Tianyu better than them. Although she always kept her word, there were still buts. After all, the Mu Clan siblings paid more attention to Haili University than others.

"Ah Yu, give me some face. This matter could be scaled down and settled peacefully. Uncle Song still wants to work for Haili for a few more years," Song Ling said.

Song Ling knew Mu Tianyu better. She was giving him a way out, but she did not want her sister to be wronged.

Mu Tianyu did not reply. Her elegant face remained cold. If not for her grandfather's high regard for Haili, she would not have shown mercy. Thus, this was the only time.

"You guys should apologize to Mu Tianen. As a teacher, you should believe in your students and not make malicious guesses without evidence." Song Ling looked at the subordinates who were so scared that they were about to tremble.

Some teachers immediately rushed to apologize to Mu Tianen.

"Tianen, we have misunderstood you. We are too narrow-minded."

"Yes, yes, yes. Tianen, we didn't mean to do it. Forgive us."

"Mu Tianen, I am really sorry."

Except for the head of the department, he failed to say anything. The mathematics teacher pulled his sleeves and urged him anxiously, "Hurry up, director."

Mu Tianyu's cold gaze was very indifferent, but it made the dean very uneasy. He was really afraid, but he failed to apologize to a student. He was struggling.

"Old Qin, there are some things that you have to admit if you did it. If you miss out on the opportunity, there will be no more." The third-grade dean said.

He was reminding him that if he continued to dawdle, Mu Tianyu would really not show mercy.

Hearing this, the head of the department looked at Mu Tianyu. There was no expression on his face, but he knew that she would not let go of this matter. He closed his eyes and said, "Mu Tianen, I misunderstood you this time. I'm sorry."

When Mu Tianen heard the teachers apologizing to her, she immediately forgot about this matter. Her pursed lips loosened, but she could not say forgiveness. It was not good to be wronged.

Mu Tianyu noticed and looked at Song Ling again. She secretly swallowed her anger. Except for the slight change in her eyes, her beautiful face was still cold. "This time, it will only happen once. If there is a next time, I will let your professional careers end here."

No one dared to question Mu Tianyu's words. They all nodded and secretly heaved a sigh of relief in their hearts.

A moment later, only the two sisters, Mu Tianyu and Mu Tianen as well as Song Ling were left in the principal's office.

"Ah Yu, you are still so serious and fierce," Song Ling said with a loving smile.

"Uncle Song, Mu family can't be bullied without fighting back." Mu Tianyu's cold expression disappeared, but her delicate and beautiful face was still expressionless.

Mu Tianen looked at her sister with her big black eyes full of admiration. "Sister, you are still the best. I explained as much as I can but the teachers still didn't believe me."

"That's because you are not strict enough."

Mu Tianen tilted her head and thought about the meaning of this. She frowned slightly and looked very puzzled.

"Ah Yu, Tianen is still young. It's better to keep her innocent and cute. And you should be more relaxed like Tianen." Song Ling looked at the two sisters.

Hearing this, Mu Tianyu did not refute it. Her younger sister was responsible for being innocent and cute, and she was responsible for protecting her. She was not afraid of being seen as a bad guy.
