The legitimate daughter was reborn, and the emperor’s little Jiaojiao went crazy.

After several blows, Yuan almost went crazy.

She screamed and opened the box lid, revealing the neatly arranged medical books. Her eyes were scattered, thinking that the boxes of silver that were moved out were all evidence of beheading.

She hoped that there were also silver and gold in Kang Chenyan’s boxes.

Reluctantly, she opened the second box, which contained medical books as well.

The third box still contained medical books.

The fourth box... No, she felt there were banknotes inside.

She rushed forward, picked up a book at random and flipped through it. Nothing! She pulled out another book and flipped through it, still nothing!

The lids of the boxes were all opened, revealing the medical books that Kang Chenyan had bought with his salary over the years without having to spend any money on food or clothing.

This is his personal property and does not belong to the Kang family, so he wants to take it away.

He just looked at the woman coldly as she flipped through the books and muttered, "Silver, all silver, all silver..."

Kang Chenyan said goodbye to his stepmother with a smile, took a step back, and bowed deeply, "Take care, mother. I am going to the capital to work as an imperial physician in the Imperial Hospital. It is better for your own son to take care of you."

Yuan's eyes were red with anger when she heard this.

After giving birth to Kang Chenyou, she suffered a physical injury and had no more children, so she loved this son especially. She was also worried that the illegitimate son would steal the limelight from her biological son, so she was mean to him in every way.

If Kang Chenyan had not secretly listened to his uncles discussing medical theories and read medical books in private when he was a child, he would not have lived to this day.

After much hardship, he lived until he was thirteen, and then he immediately asked his grandfather to join the army. From then on, he rarely returned to the Kang family except to move the medical books he bought back to the yard for storage.

He was not afraid of what Yuan would do to him again, but he was worried that he would lose his original intention by harming Yuan.

Yuan gnashed her teeth and glared at the bastard. "Your father was beheaded. How far do you think you can go in your official career? You will always be branded as the 'son of the sinner Kang Jingliang'!"

Kang Chenyan was neither angry nor smiling, but still gentle and elegant, with an indifferent voice, "Then the mother must live a long, long time, watching her son rise step by step, enjoying wealth and glory. The son will marry and have children, and teach the children to respect life and fear cause and effect. Because..."

He dragged out the last word and looked up at the sky. "The rules of this world always have retribution."

Yuan felt a sudden chill run up her spine and her eyes widened.

Then I heard the bastard say in a calm tone, "The Kang family has been military doctors for generations, and my mother was also born into a family of doctors, but my aunt died of the 'Seven Day Wind'."

Yuan's lips trembled. "You, your aunt was weak and caught a cold. She died of it. Everyone knows it."

There was a long-brewing fire flickering in Kang Chenyan's eyes.

The flame was only a tiny spark at first, and then it grew stronger with the grief in his heart, but his voice was still very restrained, "My aunt has been dead for half a day, and you are in a hurry to have her buried without waiting for my father to come home to take a look."

"She was coughing up blood and had a contagious febrile disease..." Yuan used this reason to hastily bury her concubine without arousing anyone's suspicion.

"Really?" Kang Chenyan raised his eyes and looked at Yuan quietly, "Didn't you deliberately frame my aunt for stealing and punish her to kneel on the jade? You had already covered the jade with rust and mud, and after my aunt knelt on it, you pressed a basin of water on her calves to prevent her from getting up. Her knees were covered with blood and wounds. After the punishment, you forced her to wash her clothes in the cold wind. Because of this, my aunt didn't survive seven days. She had a bitter smile on her face when she died..."

He had always thought that his aunt smiled bitterly because she didn't want him to worry. Later, when he entered the military camp and went to the battlefield, he saw that the soldiers liked to bury the arrows in horse manure, and then he knew what it meant to kill people invisibly.

Being hit by an arrow is not scary, but being hit by an unclean arrow is scary.

Her aunt's wounds became infected because she was punished by kneeling, and she was forced to wash clothes in the wind, which caused her body to become stiff, her mouth to be unable to open, her hands and feet to cramp, her limbs to tremble, her bone marrow to ache, her face to be crooked and her mouth to look like a bitter smile.

This is exactly the symptom of "Seven Day Wind".

Kang Chenyan pointed to the sky and said, "My aunt is watching from heaven what my mother did. Look, retribution has come."

While the two were talking, the servants had already carried the boxes one by one onto the carriage waiting outside.

It was already getting dark, and the spring rain was chilly.

Kang Chenyan walked out of the yard, thought for a moment, and then came back, with a low and gentle tone, "These years, it would have been easy for me to kill my mother. But I was afraid of dirtying my hands and getting involved in karma. So I chose another way to avenge my dead aunt. Mother, do you want to guess what it is?"

Yuan was shivering in the spring rain, her lips were dark purple, and she was in a state of panic. She looked at the bastard's bottomless eyes, which looked exactly like the woman's, and suddenly took several steps back.

It was only then that Kang Chenyan's mouth was stained with a wicked smile. That smile spread in the spring rain, spread in the twilight, and turned into wind and snow to bury Yuan.

Princess House.

Shi Anxia looked at the letter submitted by the Inspector and fell into deep thought.

Without this letter, the inspector would not have been able to collect conclusive evidence that Kang Jingliang and his son embezzled disaster relief funds in such a short period of time.

The letter not only listed the specific time and amount of money that Kang Jingliang and his son embezzled for disaster relief, but also included detailed account records and relevant physical evidence clues.

In addition, the letter also listed the approximate amount of silver that the two had embezzled in the past, and described in detail how they falsified accounts and covered up their crimes.

There was even a map on the letter, showing the location of the hidden relief money, the old house and many other villas, all accurate.

It would be impossible to know this in such detail if it weren't for years of careful observation.

Shi Anxia handed the letter to Cen Yuan and said, "Look, this Kang Chenyan is also a capable person."

Cen Yuan read it for a long time and put the letter aside. "I think if we were not preparing to return to Beijing, he would continue to hide the evidence."

Obviously, some of these were just Kang Chenyan's guesses, without any substantial evidence. This person was indeed a very logical person with a severe obsessive-compulsive disorder, and he would definitely find the evidence thoroughly before handing it over to the inspector.

Kang Chenyan clearly wanted to shoot his father and brother in the throat with one arrow.

This is a ruthless person.

As the two were talking, Bei Hui came to report, "Doctor Kang wants to see you."

Shi Anxia's eyes fell on the letter and she ordered, "Let him in."

A moment later, Kang Chenyan arrived. After paying his respects, he got straight to the point and said, "Princess, Prince Consort, the anonymous letter reporting my father and brother was written by me."

Shi Anxia raised her eyebrows slightly, "Since it's anonymous, why bother to point it out?"

Kang Chenyan pondered for a moment and replied, "I still want to try my best to marry Miss Xiyue. I am willing to expose my most shameful side to the princess to show my sincerity."

Shi Anxia pointed at the letter with her finger, "What is the most unbearable side? Killing one's relatives for the sake of justice?"

Kang Chenyan nodded, lowering his eyebrows, "My aunt died in the 'Seven Day Wind'..."
