Father, who is both a heir and a descendant, is still biased; the bound system has gone berserk.

Meng Wanli knew that her request was outrageous, but for the past three years, she had always felt that her parents' deaths were unusual.

"Your Highness, although I do not have direct evidence to prove that my parents' deaths were suspicious, I do have other evidence."

Ok?

Everyone looked at her curiously.

Meng Wanli said, "Your Highness, Princess Anguo, there is a pear tree in the backyard of the Meng residence. There are some things buried under that pear tree in the southeast direction. Go and dig them up."

"I'll go," Wushuang said.

After saying that, she vanished into the woodshed.

Wu Shuang was incredibly skilled, and Shangguan Fei's eyes lit up as she followed him out.

In the woodshed, Meng Wanli continued, "His Highness the Crown Prince and Princess Anguo should have discovered the situation at Anzhou Fishing Lake by now, right?"

Starting two years ago, Anju, which was originally abundant in fish and shrimp, suddenly became unable to support them, and now there are piles and piles of rotting fish and shrimp.

Ying Yufu nodded. "We know that the fish and shrimp were rotting and piled up by the lake. The people pushed them into the pit to bury them. Today, we found the bodies of a family surnamed Zhuang under the pile of fish and shrimp. There were six bodies, and the seventh one is still alive."

"Surname Zhuang?" A hint of surprise appeared on Meng Wanli's face, followed by a flash of understanding. She gave a smile that was both mocking and sarcastic.

"They really are ruthless."

Ying Yufu and the Crown Prince exchanged a glance. Ying Yufu asked, "Miss Meng, what do you know? Tell us."

Meng Wanli looked at them and said, "I have nothing to hide. I'll tell you everything I know."

She said, "There is a girl in the Zhuang family named Zhuang Cuiluo who saved Meng Dongpei. Meng Dongpei fell in love with her at first sight and vowed to marry no one else."

My grandparents, my second uncle, and my second aunt would naturally not agree to Meng Dongpei marrying a peasant girl.

They strongly opposed it, but he couldn't resist Meng Dongpei's insistence on being with the peasant girl.

The family had no choice but to agree on the surface.

I guessed they would target the peasant woman, but I never expected they would even attack her family.

"Miss Meng, are you saying that the murders of the Zhuang family were committed by your grandparents, your second uncle and aunt?" Ying Yufu asked.

"There's no one else but them. Even if they didn't do it themselves, they're still the culprits, but I have no proof."

Meng Wanli spoke calmly, yet with unwavering certainty.

Just then, Wushuang and Shangguan Fei returned at the same time.

Shangguan Fei was holding a small purplish-red wooden box in her arms.

Meng Wanli saw it and said, "This is it."

She stepped forward, took the small wooden box from Shangguan Fei, opened it, and inside was a small black booklet.

Ying Yufu glanced at it and saw the words "Longevity Technique" written on it.

"The art of immortality?"

Ying Yufu was very surprised. Could there really be such a book in the world?

The previous emperor was obsessed with alchemy in pursuit of immortality, but in the end, he died young.

Why would the Meng family have such a booklet?

Meng Wanli nodded: "Yes, the art of longevity. This contains a record of an evil technique for refining longevity pills. I found it in a secret room in the Meng family's study."

Actually, my grandfather and second uncle started acting mysteriously three years ago, and later even mentioned that they wanted to refine some kind of longevity elixir.

At that time, my parents were still alive, and my father used the example of the previous dynasty to stop my grandfather and second uncle.

After hearing what Father said, Grandfather and Second Uncle indeed stopped mentioning it.

Three years ago, after returning to Anzhou, I vaguely heard them mentioning longevity pills again, but my parents had already met with misfortune.

Two years ago, when things started going wrong at Anju Yuhu, I realized it might be related to them.

The wastewater and residue from alchemy were extremely toxic. Three years ago, when I first returned to Anzhou, they poisoned all the koi in the pond in my mansion, and the incident caused quite a stir in the mansion.

Later, they dumped all the waste and wastewater into the lake.

After about a year of this, problems began to arise at Yuhu.

At first, people who ate the fish and shrimp died from poisoning, and later, a large number of fish and shrimp died, and Anju Fish Lake became a dead lake.

The key issue is that the fish and shrimp were poisoned, yet they reproduced much faster.

They reproduce and die simultaneously, making it impossible to completely eradicate them.
