"Su Wenzhong’s greatest wish was to make Su Family’s grandson the new Crown Prince of Dayan, but I wouldn’t let him succeed. To take revenge on him and Rong Jing, I used a unique poison... to deprive Rong Jing of the ability to impregnate a woman from then on."

From then on, after giving birth to Miaoyan, she bore no more children. Su Wenzhong had to resort to schemes, adopting Rong Qichun, whose birth mother died early, under her name as her legitimate son.

Su Zhixue finished speaking, revealing a satisfied and cathartic smile.

"I have no regrets about this matter."

She recalled a month ago when Zhang Fengcai delivered an incense burner by imperial decree.

Su Zhixue and Zhang Fengcai were old acquaintances, though they had no interaction, they had familiar ties from their time in the Eastern Palace. The latter handed her the incense burner but shook his head at her.

Back then, she had a maid deliver a Sweet Pine Fragrance incense burner to Crown Prince Rong Jing, which was no different from ordinary Sweet Pine Fragrance. The issue lay with the incense burner itself.

She knew, given Rong Jing’s nature, he would definitely use the incense she sent him to demonstrate the Crown Prince’s affection towards the Crown Princess Consort.

Therefore, Rong Jing was very likely to use the incense burner as well.

If he didn’t use it, it meant he was destined to escape this disaster. If he realized there was a problem with the incense burner, she would deny it to her death, and what could Rong Jing do to her?

Later, when Su Zhixue married into the Eastern Palace, she indeed saw Rong Jing using that incense burner.

In just thirty days, the poison would seep into his internal organs, rendering him...

Rong Jing thought that because she was a woman, subjected to humiliation, she wouldn’t dare resist and would meekly accept her fate!

He thought she would still succumb to family and fatherly pressures, accepting her fate!

No, the hatred in her heart could never be erased, and it required blood to be repaid!

Su Zhixue understood that man; the reason he had Zhang Fengcai deliver the incense burner was to tell her he knew everything.

Rong Jing wanted her to spend her final days in fear, anxiety, and trepidation.

And the reason that man hadn’t killed her yet might be out of consideration for Miaoyan’s thoughts, or perhaps he wanted to first punish "Little Wu" who betrayed him. When he had the chance, he would definitely make her die.

But Rong Jing was wrong; she was a mother, with Miaoyan there, she was no longer afraid of his threats or insults. For Miaoyan, even with the determination to die, she must kill him!

Gu Lan raised a hand: "...That’s a lot to take in, Third Sister-in-law, give me a moment."

Su Zhixue had poisoned Rong Jing, making him infertile... even from over ten years ago.

The secrets she revealed tonight were more than all the secrets she knew after entering the book.

Compared to Miaoyan being the daughter of Rong Jue and Su Zhixue, and Su Zhixue being a ’white-to-black’ personality, the fact that Rong Jing was made infertile by Su Zhixue, what did her cross-dressing as a man matter?

The Rong imperial family, no, it should be said the Su family... how could it be such a mess?

No wonder Rong Jing, as an Emperor with a normally sized harem, had such few offspring: just the two useless sons, Rong Qichun and Rong Qijun, both had during his youth as Crown Prince.

After ascending to the throne, Rong Jing treated all equally, yet the concubines of the harem remained childless because he’d already been rendered impotent by Su Zhixue.

Gu Lan suspected that after stepping into the pages of Dayan Wind and Cloud Record, she hadn’t come to fill the void of a missing female lead but rather to uncover old secrets and origins, acting as a private investigator!

Brother Hang had it worse,

He thought his enemy was his own father, not expecting that the enemy was his brother, but in truth, his brother wasn’t his brother, his second sister-in-law was actually his third...

At least she could confirm she was the biological child of Marquis Gu and Madam Zhou!

After a while, Gu Lan snapped back to reality: "Please continue."

Having stained her hands with blood, it naturally wasn’t just Rong Jing’s blood. Su Zhixue hadn’t yet explained why she killed that concubine’s child.

Su Zhixue’s lips curved into a bitter arc and said:

"After poisoning Rong Jing, I knew he could never allow any concubine to conceive, so any concubine in the harem with a child would be determined to have had an affair."

Gu Lan’s pupils widened; this logic was undeniable. It meant Rong Jing had more than one affair, but Su Zhixue...

"To prevent those children from confusing the Rong family’s reign..." Su Zhixue didn’t need to finish. Gu Lan already understood her meaning.

She looked at that serene and exceptionally beautiful face, her heart suddenly filled with coldness.

"You killed them."

"Yes, I knew full well those children were innocent, yet I still did it... This is the sin I committed, I know, Rong Jing deserved death, and so do I. Over the years, perhaps I’ve gone mad, driven insane by this man-eating Imperial Palace."

Su Zhixue spoke, enunciating each word clearly.
