Guo He was the most intelligent student Teacher Yu had ever had. He was able to top every exam he sat for. Meanwhile, Shang Zhuo was his most talented and well-behaved student. They were both his favourite students. Now, Guo He was dead. If Shang Zhuo was really the killer, he had to pay for the crime he committed. For both of his favourite students to be taken away in such a manner, it was akin to carving out his own heart.

　　Unlike Lin Shu, who got furious when he was accused of being the murderer, Shang Zhuo remained calm as usual. He went forward to help support Teacher Yu who was quivering and he explained, "Teacher, I did not kill Guo He. However, I admit that I was the one who wrote the letter Guo He left behind with my left hand."

　　Teacher Yu bent forward as he yelled with a croaky voice, "Why did you fake the letter if you weren't the killer? Tell me, were you the one who pushed him down the well and forged a counterfeit letter afterwards? Did you lie, telling everyone that Guo He had left the academy, in order to hide his death during for the past year?"

　　"I would never do such a thing," Shang Zhuo repeated, this time in a sombre manner. He sounded confident and resolute.

　　However, Teacher Yu harshly pushed Shang Zhuo's hand away. "Are you still not admitting it? As it is, it is clear that you lied about the letter. You wrote the letter and personally handed it to me, claiming that it was from Guo He. Why did you do that if you were not the killer?" He lost his balance when he finished his words and stumbled back a few steps. Fortunately, Ji Yunshu was standing behind him and caught him.

　　Ji Yunshu had already formed her opinion but decided to hold back and listen to what Shang Zhuo had to say.

　　Gently furrowing his brows, Shang Zhuo grimaced, cracking his calm expression. He took a deep breath before he said, "I did not lie to you at all. Although I faked the letter, Guo He certainly did pa.s.s me a letter before he left. What I just said is true. I hope that teacher can believe me."

　　Hey, brother. Do you know how contradictory your words sound right now? You are telling us that you wrote the letter, but Guo He handed the letter to you before he left? Is this some paranormal incident?

　　Teacher Yu had had a very eventful day and he was not able to take another blow. Moreover, his health had not been well at all. At this moment, he was very close to fainting.

　　Ji Yunshu quickly said, "Teacher, please stay calm. This humble one has said that the letter is insufficient evidence to identify the killer. A mere letter doesn't prove that he's the murderer."

　　"Then... then, what?"

　　"Please have a seat first, Teacher." She helped him to take a seat.
