Xiao Weiji was like a frog illuminated by a flashlight late at night. He remained motionless with his head raised from his knees, staring at Xiao Xingyu with astonished eyes.

Although Xiao Xingyu's question was a question, his tone was very firm. He didn't even add a sentence structure like "If I'm not mistaken" before his conclusion, which shows that he was very confident.

"I didn't, it wasn't me!" Xiao Weiji denied it hastily after he came to his senses.

Xiao Weizhou didn't understand what was going on, but he absolutely believed in his son's intelligence, so he asked Xiao Xingyu: "Xingyu, how did you know that this letter was brought by Weiji?"

Xiao Xingyu flicked the envelope with his slender fingertips, turning it back and forth in front of everyone. "This envelope has the words 'Personally addressed to Mr. Xiao Guotao' written on it. I believe it's Zhang Shunqing's handwriting. It has no postmark or address, so there's no doubt it wasn't mailed. Grandpa just said that this letter appeared on his desk that year, so we can be sure that someone must have left it on your desk."

The eldest aunt was a little confused and said in confusion, "Of course it is! But the factory area was different twenty years ago. The entry and exit management was not so strict. Zhang Shunqing has worked in the factory for many years, so it wouldn't be difficult for her to get into Dad's office without being noticed."

Zhang Moyan stared at Xiao Xingyu standing before her. Sunlight streamed in through the ancient window sills, illuminating his tall figure. Tears welled up in her eyes as she looked at the man who had stood up for her against all odds. Suddenly, a sudden realization flooded her, and she realized—she was no longer alone. Xiao Xingyu had stood by her side, facing this bizarre and unpredictable fate with her.

"Yes, that's right," Xiao Xingyu nodded, confirming his aunt's statement. "Anyone familiar with the factory layout could have entered Grandpa's office unnoticed. So, that person must be Zhang Shunqing, right?"

The air was quiet for a while, and everyone's mind was following Xiao Xingyu's.

Xiao Xingyu pointed to a line of handwriting on the letter and said, "Everyone should have seen this content. Zhang Shunqing wrote that he would be dead by the time Grandpa read this letter. Even a child like me knows what Grandpa was like before he retired. He worked more than ten hours a day. If this letter was not mailed, but was delivered by Zhang Shunqing personally that day, then it would definitely have been discovered by Grandpa soon. Zhang Shunqing could not have failed to predict this, so he had to die quickly to ensure that he was no longer alive by the time Grandpa read the letter. If he wanted to die quickly, he had to die in Ruzhou. But if someone died in Ruzhou, it would definitely be big news. How could you have known nothing about it and thought Zhang Shunqing was missing for so many years?"

As everyone listened to Xiao Xingyu's analysis, they gradually figured things out, revealing belated realizations. Xiao Huai couldn't help but agree, "Zhang Shunqing couldn't have been so hasty."

Xiao Guotao, who had been silent for a long time, slowly spoke up, "I've never thought of this. I've been carrying this letter for so many years in vain! ... Xingyu's reasoning is sound. Ever since I received Shunqing's final letter, I've been paying close attention to local news and even visited surrounding counties and towns to inquire about suicides, but there's been no news."

Xiao Xingyu concluded, "So, Zhang Shunqing must have left the suicide note somewhere other than with Xiao Sheng, and he was very sure someone would find it someday. He even trusted that person to help him deliver the letter to Grandpa, and even if he read the contents of the letter, he would never reveal it to anyone."

As Xiao Xingyu spoke, his gaze gradually shifted to Xiao Weiji, who was trembling on the ground. He approached him step by step, "This person is most likely a former colleague of his. This explains why you, Uncle Weiji, knew the contents of Zhang Shunqing's suicide note. Then, more than 20 years later, you accidentally leaked the contents of the suicide note to your son and daughter-in-law on some occasion. Influenced by Zhang Shunqing's emotions in the letter, your family hated Chen Yun immensely. Am I right, Uncle Weiji?"

The moment Xiao Xingyu's shiny black leather shoes pressed against Xiao Weiji's eyelids, Xiao Weiji suddenly jumped up, pushed Xiao Xingyu away, turned around and ran towards the door without caring anything!

There was an uproar in the main hall. Xiao Xingyu had not expected this to happen. When he reacted, Xiao Weizhi had already run out of the courtyard like a desperate criminal.

Just as he was about to give chase, he saw Xiao Yanzhen and Dai Xuan coming towards the main hall. They were about to run into Xiao Weiji head-on, so he shouted loudly, "Xiao Yanzhen, stop Uncle Weiji quickly and bring him here!"

Hearing this shout, all the men and women in the Xiao family frowned and looked at Xiao Xingyu in unison. He called the eldest elder in the family by his name, and in this tone. The Xiao family had never produced such a bad son who did not distinguish between the old and the young in 800 years.

However, the elders actually listened to him. A man and a woman immediately used mixed doubles to catch Xiao Weiji like an eagle catching chickens. Especially the young and beautiful grandmother Taizu in red, her fighting power was off the charts even with the dragging and pulling.

The three brothers Xiao Weizhou immediately stepped forward to persuade Xiao Weiji, appealing to his emotions and reasoning with him. After a long and earnest speech, they finally brought Xiao Weiji back to the main hall.

"Why are you running?" Xiao Xingyu gave Xiao Weiji a wry smile.

Xiao Weiji glanced at Xiao Xingyu timidly, then immediately turned away and said stiffly and stubbornly, "I delivered the letter. I admit it! You've all read the contents of the letter. Chen Yun deliberately came to our Xiao family for the Tianqing glazed porcelain. She was the one who killed Uncle Guoxi! This is what Shunqing wrote. I have nothing to say!"
