Yi Chuan quietly followed behind Xin Yi, not far from her.

Xin Yi asked, "The king of the county is not in these days, but he is still calm?"

Yi Chuan's brows frowned inadvertently, "Ge Yong has been here to try a chicken thief."

Xin Yi snorted, "...... Sima Zhao's heart."

Yi Chuan: "I didn't let him see Yu's mother and son."

This is a gloomy young man, who speaks concisely and does not smile, but unlike Cheng Cang's calm and restrained, he obviously has a pair of gentle eyes, but he is dulled by that melancholy face.

His presence is extremely low.

Xin Yi thought about it carefully, and had seen it countless times, but he couldn't tell what kind of person he was.

She said, "It seems that this Lord Ge has been an official for many years, and his hands and feet are not very clean, so he is so nervous. Fortunately, you are here, otherwise, I don't know what kind of storm this old fox would have turned over."

Luan Chuan looked over expressionlessly, "How did the county king disappear?"

Xin Yi hesitated, looked at Xingyuan on his side, and briefly told him the news that Duan Sui had brought back.

After walking for a while, Luan Chuan suddenly stopped.

"Here we are."

Xin Yi stopped talking and looked up.

The dungeon was dimly lit, and only a square inch could be seen.

Yu's mother and son were guarded separately, and the two dungeons, one on the left and one on the right, were lined up on both sides, and they had to enter through the same iron gate. Several jailers in poor uniforms stood guard outside the iron gate with waist knives on their shoulders.

In front of the night room outside the iron gate, there were two guards in soft armor, and when they saw Luan Chuan and Xin Yi, they hurriedly got up and saluted.

Luan Chuan raised his chin, "Open the door!"

The guards clenched their fists, "Yes......"

The key inserted into the keyhole makes a cold sound, bringing a chill to the bones in the silence. z.br>

With a clang, the iron door opened, and the flame of the oil lamp reflected the figures in the prison.

Xin Yi was slightly surprised.

Yu was already asleep, prostrate on the dry straw, his body curled up like a corpse.

Opposite her, in the same humble dungeon, sat her son, who contrasted with her. He was dressed in neat prison clothes, his hair was neatly tied, his hands were spread on his knees, and his back was leaning straight against the wall. If he hadn't raised his head suddenly, the unmanageable beard under his jaw and the unconcealable consternation exposed the embarrassment of being in prison at the moment.

"Dr. Xin is here?"

As soon as he opened his mouth, he had a gentle look.

Is this guy a blank slate, or is he hiding too deeply?

Xin Yi looked at him quietly, through the fence made of iron and wood, as if looking at a stranger.

"What's wrong?" Yu Du seemed to have a smile in his voice, "The old man came to see me, just to see me?"

Yi Chuan drank coldly: "Talk to the princess of the county!"

Yu Du raised his hands and gave Xin Yi and Luan Chuan a deep squeeze.

"I know what I think, I have already told the king of the county that day, I don't know what else to say......

He paused slightly, looking at the motionless Yu in the prison opposite.

"I really didn't know about my mother's affairs, and I was surprised to hear that there were dried corpses and secret passages hidden in my house. The house in Shuimo Lane was originally rented, but then the owner moved his family to Bianjing and transferred it to my family cheaply, and that's all I know."

Compared with Yu's "no explanation", Yu Du did have questions and answers, but none of them were to the point.

Xin Yi squinted at his expression, calm, calm, and not afraid.

She sneered, "Young Master Qingyu is very good at disguise. I underestimated you before."

She glanced back, and Xingyuan brought a stool from the night room and placed it outside the cell door.

Xin Yi sat down slowly, and said lightly:

"What's so strange about the song of the cave immortals on the cliffs of Hump Ridge? I want you to tell the truth."

The smile in Yu Du's eyes was shallow, and his expression was softer than Fang Cai.

"That's what it was

one."

He seemed to breathe a sigh of relief, then sat cross-legged in front of Xin Yi, and smiled warmly at her through the cell door:

"Back then, I met a distinguished guest on the twelfth floor and said that he wanted to build a Taoist temple in the Hump Ridge Mountain. It is also said that Hump Ridge has a fairy fate, and it will be able to live a long life. He made two silver taels to the next, please write an inscription for him below, chiseled on the fairy wall. In the next nature should be from. At that time, what I thought of was the "Song of the Cave Immortals" taught by my mother, and I wrote it out for the distinguished guests to see, and he liked it very much, and then gave it to the next crane inkstone. The inkstone is now on the desk in the inner room of the house, and if the adults don't believe it, they can take it as proof."

Xin Yi looked at him silently.

"Who's your guest?"

The corners of Yu Du's lips lifted, and he sighed faintly.

"I'm ashamed to say that I ate a lot of wine that day, and I remember that he told him about his place of residence, but when he woke up, he completely forgot about it. Why, is there a problem with the Taoist temple in Hump Ridge? Something to do with this case?"

Xin Yi's eyes did not move, and he looked at him with a smile.

"Has Young Master Qingyu ever been to Hump Ridge?"

Yu Du shook his head, "No."

Xin Yi said, "There is no Taoist temple in Hump Ridge."

"Really?" Yu Du said suddenly, "That distinguished guest, could it be that you are coaxing me?"

Xin Yi looked at his still calm face, as well as his slightly shaky facial features under the dim night light, and groaned for a moment.

"I'll ask you one last time, you really don't know what's going on in Hump Ridge?"

Yu Du shook his head in confusion, his brows furrowed slightly.

"Dr. Xin is still suspicious of my ......"

His throat throbbed, and his voice was much lower.

"Even if I were to deceive everyone, I would never lie to you. You are my savior. If it weren't for you, I would have died when I was in Bianjing."

Thinking of this, Xin Yi's eyebrows twitched slightly.

"Do you know how you got that disease?"

Yu Du hesitated, and an obscure smile appeared in his dark eyes.

"The king of the county first said that I know."

Xin Yi said calmly, "The giant flower aristolochia in your yard is the culprit. Don't you have any doubts that your mother planted such strange flowers at home?"

Yu Du lowered his head in shame and said, "I just thought it was an herb that blindly calmed asthma and suppressed cough, although it smelled uncomfortable, but it often had miraculous effects......

His voice was slightly muted, like a memory.

"I was young and poor, and I didn't have money to go to the doctor. If I have a cold or cold, my mother always prepares some herbs for me to take."

"Don't you smell disgusted by that stench?"

"What about the smell? How can a son suspect his mother?"

Listening to his whispered and slow voice, the smile on the corner of Xin Yi's mouth became more and more cold.

"When you cough, will your mother give it to you?"

"Hmm." Yu Du smiled again, "My family is poor and can't afford to buy medicine, so I will eat the herbs I grow, and my mother will eat them."

"Aristolochia tastes terrible, isn't it uncomfortable to eat?"

"My mother mixed it with sugar and boiling water and fed it to me, but it was bitter. But ......."

He looked up at Xin Yi and smiled calmly, "How can there be a medicine that is not bitter?"

Xin Yi pursed his lips slightly, "So, the poison of aristolochia in your body is not your mother's sincere intention to harm you, at most it is an unintentional fault?"

"Heh......" Yu Du laughed.

"There is only a father in the world who abandons his wife and children, who is a mother who harms the life of his children?"
