"We've checked each one, but haven't found any problems. So Bai Yuan's medicine might not have come from us. And from what I've learned, Bai Yuan's medicine has always been purchased by his eldest son, Bai Chengyi. If you want to know the source of the medicine, just ask Bai Chengyi."

After hearing Dang Yan's words, An Tingyu smiled coldly and curled her lips in a sarcastic tone, "It seems that Madam Bai didn't tell the truth, because in the confession that Tang Liuzhao showed me, Madam Bai said that Bai Yuan had always bought the medicine himself, so she was protecting her son."

The three siblings in the Bai family have always lived their own lives. If Mrs. Bai hadn't said anything about something like this, no one would have known that Bai Chengyi had bought the medicine. Moreover, Bai Chengyi didn't mention this in his confession. This shows that the mother and son had colluded with each other.

Upon learning of this situation, An Tingyu immediately notified Tang Liuzhao and then came to Bai Mansion again.

"Mrs. Bai, why did you give a false confession? Do you know that by doing so you might allow the real murderer to go unpunished?" An Tingyu said coldly.

Mrs. Bai pinched her fingers nervously and kept her head down. "I...I didn't mean to do it, but my husband is dead. I can't let my son go to jail. And I believe Cheng Yi is not the real murderer."

"Do you really believe it?" An Tingyu raised her lips sarcastically, and then said, "Bai Chengyi is addicted to gambling. Now he even ignores you, his old mother, for the sake of the family property. How can he be credible? Madam Bai, stop deceiving yourself."

In fact, An Tingyu could understand Mrs. Bai's thoughts. There is no parent in the world who is not a parent. However, a loving mother may lead to the failure of her son. Bai Chengyi might be the real murderer who killed Bai Yuan. Mrs. Bai wanted to save her son, but had she never thought about whether she was worthy of her husband?

"Miss An, please stop pressuring Madam," Lan Chun walked in. She stepped forward to support Madam Bai and said, "Actually, Madam is not to blame for this. She was about to tell, but the eldest young master begged her. He said that if the officials knew he had been buying the medicine, they would frame him for murder even without evidence. Madam couldn't bear to lose both her husband and her own child, so she had no choice but to agree."

Hearing this, An Tingyu sighed secretly. Mrs. Bai was a good mother, but sometimes being good was not enough.

"Let Bai Chengyi in!" Tang Liuzhao ordered.

"Yes!" The yamen runner who had come with Tang Liuzhao answered and left, but soon came back running, "Sir, this is bad. Bai Chengyi has fled for fear of punishment. Look, this is the letter we found in Bai Chengyi's room."

"By the way, I saw the eldest young master when I was hanging clothes in the backyard just now. I was about to call him, but he left." Lan Chun said again.

"He might have wanted to escape by then, so hurry up and chase him!" As soon as Tang Liuzhao gave the order, the yamen runners immediately came out in full force. He turned around and said to An Tingyu, "I'll go and take a look too," and then left.

"Could it really be Cheng Yi?" Mrs. Bai was heartbroken and almost fainted. If it weren't for Lan Chun who was supporting her, she would have fallen to the ground.

"Madam! Don't think too much. The eldest young master may just be afraid of being wrongly accused. His escape does not mean that the fake medicine incident is related to the eldest young master. Miss An and the others will find out." Lan Chun said comfortingly.

Seeing her so sad, An Tingyu had no choice but to say, "Mrs. Bai, Lan Chun is right. You don't have to be too desperate. Before the matter is investigated clearly, Bai Chengyi is only a suspect, not a conclusive criminal."

Mrs. Bai just cried softly and did not respond to An Tingyu's words, but An Tingyu knew that Mrs. Bai's heart had sunk to the bottom of the valley.

After Bai Chengyi's escape, Tang Liuzhao sent out all the yamen runners to conduct a carpet search throughout the city. However, after three days, they still found nothing and finally had to return empty-handed.

"Can he escape underground?" An Tingyu always felt something was strange, but she couldn't tell what was strange.

"I don't know whether he can escape underground, but I know one thing, Bai Chengyi must have escaped from my pursuit range now. It's... difficult to catch him!" Tang Liuzhao sighed helplessly.

He was a new official and should have made his first move, but his first case was so difficult and the suspect escaped. If he didn't find out the truth, he would be stripped of his official position.

"By the way, has Mrs. Bai checked the handwriting of Bai Chengyi's letter?" An Tingyu suddenly thought of something.

Tang Liuzhao was stunned for a moment, then slapped himself on the forehead as he came to his senses. "Look at me, I've been so busy these past two days that I almost forgot about this. I'll go now and tell you when I have the result."

After saying that, Tang Liuzhao hurried to check, but the final result did not change at all, because the handwriting in the letter was indeed from Bai Chengyi, not someone else, so the possibility of Bai Chengyi absconding for fear of crime was greatly increased.

"Could it be that Bai Chengyi really fled for fear of punishment?" An Tingyu asked herself, and then answered herself, "Impossible..."

"What's impossible?" As soon as he entered the door, Feng Beijian heard An Tingyu talking to herself, nodding and shaking her head, as if she was thinking hard about something.

An Tingyu glanced at him calmly, then said: "I'm talking about Bai Chengyi. At first, I thought he was very suspicious, but then I thought, we hadn't started questioning Bai Chengyi at that time, so how did Bai Chengyi get the news? And who told him that the matter was exposed? So the timing of his escape was too coincidental. The most important thing is the letter. The letter only said some words similar to confession, but did not say that he was absconding because of the fake medicine that harmed people. So I think things may not be as simple as we thought. There may be a conspiracy to seize property. Because Bai Yuan is dead and did not make a will, Bai Chengyi is the first heir and the person who prevents others from obtaining property."
