"It's very simple. Zhang Qiang was afraid that Xiao Yun would expose the truth and would naturally follow behind her every day. When he found out that someone was secretly investigating the case, he knew that he could not escape so he took the poison and committed suicide." Hai Yang explained to Zhining.

There was also a certain truth in the Southern Ocean's words, and Zhining had no way of refuting it. However, what if …?

"My lord, what you say is not without reason, but what if …? If there really was a mastermind behind all this, wouldn't Bing'er be in danger? Since the mastermind behind the plot was able to make Zhang Qiang and Xiao Yun poison Cai Die to death and blame it on Liang Yuqi, it goes to show how scheming she is and how vicious her heart is. For Bing'er's safety, this subordinate pleads for you to send someone to protect Bing'er from the shadows. " Although she and Lu Shao would also protect Bing'er, she was afraid, afraid that she wouldn't be able to protect Bing'er.

After saying this, ZhiNing kneeled down on one knee, looking pleadingly at Southern Sea.

Nanhai purposefully ignored Zhining's pleading eyes, once again picking up the brush he had placed on the table and handling the documents, ignoring Zhining who was kneeling on the ground.

When he saw that Zhining was still kneeling in front of him, his handsome eyebrows couldn't help but tightly furrow together, "I still have important matters to attend to. If there's nothing else, you can leave."

"Lord?" ZhiNing looked pleadingly at Southern Ocean, hoping that he would change his mind.

However, Southern Sea didn't even look at Zhining, just continued to handle some of the documents.

Without even looking at her, she knew that it was impossible for Nan Hai to send anyone to protect Bing'er. She sighed to herself, then stood up from the ground and respectfully looked towards the Southern Sea, "Your subordinate will take his leave."

The Southern Ocean was still immersed in dealing with political affairs, completely ignoring Zhining, as if Zhining did not exist.

When ZhiNing said goodbye to Southern Sea, she specifically glanced at Southern Sea, hoping that he would change his mind. As long as Southern Sea was willing to look at her, she would not hesitate to plead with him. However, she was disappointed. The Southern Ocean had never seen her before, so she acted as if she didn't exist.

Zhining threw a slightly disappointed glance at Southern Sea, then quietly left the room.

Hearing the sound of Zhining gently closing the door, Southern Ocean raised his head and looked at the already closed study room with great thoughts.

"Constable Chen, someone wants to see you outside the gate." The guards at the gate reported respectfully to Zhining.

ZhiNing hurriedly walked towards the South Mansion's main gate. From afar, she could see the man dressed in purple, Bing'er walking back and forth in front of the South Mansion.

"What is it?" Zhining did not arrive, but the voice of the question had arrived first.

Bing'er stopped her pacing and said without turning her head, "Let's go to the Liang Household, we'll talk while we walk."

Liang Mansion.

Sihan ordered someone to prepare some pastries and tea before chasing the maidservant out of the room. She told the maidservant to wait outside the door.

Bing'er took out the earrings of Shang Ling'er and Cai Die and threw them on the table.

"What is this?" Sihan looked at the things on the table and asked Bing'er.

"Just open it and take a look." Bing-Er answered Sihan.

ZhiNing stretched out her hand and opened the handkerchief, revealing a pair of butterfly earrings. She held the earring in her hand and muttered, "I think I've seen this somewhere before."

Sihan opened the treasure. It was actually exactly the same as the earring in the handkerchief. It was a butterfly shaped earring.

Sian held the earring in his hand and observed it for a while, then said, "This earring's pattern is exactly the same as the tattoo on Cai Die's shoulder."

"That's right, no wonder I felt that these butterfly earrings were so familiar, I've seen them before on Cai Die's corpse." Bing-Er suddenly realized.

ZhiNing looked at the earring in her hand, "Who owns these earrings?" Bing-Er divided them into two, which meant the earrings didn't belong to the same person.

"The handkerchief is wrapped with Cai Die's. The package is for Shang Ling'er. " Bing'er answered. She picked up a piece of pastry and put it in her mouth. She hadn't eaten since she got up, so she was very hungry.

"But why is there only one earring for Shang Ling'er? Did you forget to take the other one? " ZhiNing raised her head and looked at Bing'er.

Bing-Er hurriedly swallowed the pastry in her mouth. She almost swallowed it, and when she saw that, she hurriedly gave a cup of tea to Bing-Er. Bing-Er took a big gulp and swallowed the pastry that was stuck in her throat.

She took a few deep breaths, then looked at ZhiNing, "Of course not. I searched through Shang Ling'er's bag but still couldn't find the other earring."

Sihan held a pair of earrings in her hands and looked at them, "These earrings are slow, beautiful, and very unique. It seems like Cai Die really likes butterflies."

ZhiNing waved a butterfly earring in her hand, "Cai Die likes butterfly earrings, so even her tattoo is butterfly. But why would Shang Ling'er have butterfly earrings? And it's even one. "

"Huh?" Sihan looked at the two earrings in her hands, somewhat puzzled.

ZhiNing and Bing'er looked at Sihan at the same time, "What's wrong?"

Sihan placed the two earrings in front of Zhining and Bing'er, and asked, "Did you find anything different?"

Bing'er and Zhining simultaneously looked at the butterfly earrings in front of them. These earrings were very unique, on top of a thin chain, there was a butterfly that wanted to fly high in the sky, the butterfly was small but delicate, two tiny rubies were inlaid on the silver butterfly's head, as the eyes of the butterfly, two emerald green gems were inlaid on the butterfly's wings, and two purple gems were hanging from its wings, looking very beautiful. It seemed that the owner of this pair of earrings was very fond of precious stones.

The two earrings were exactly the same. It was impossible to tell anything out of the ordinary.

"I don't see anything, do you?" Bing'er shifted her gaze to Zhining's face.

"These earrings look exactly the same, but they are one old and one new." Out of the corner of her eyes, Bing'er said proudly.

Bing'er looked at the earring in Sihan's hand and realized that one earring was a little old, but the other was brand-new. Really, it was really an old one, a new one. It doesn't look like a pair, but more like a later match. "

"I feel like these two are the real pair." ZhiNing placed the earring in her hand next to the slightly old one in Sihan's hand. The earring in her hand was slightly old. It happened to be a pair with the slightly old earrings in Sihan's hands.

The three of them looked at each other, "Are you sure you're not mistaken?" Sihan glanced at Bing'er.

"No, absolutely not. The one for Cai Die and the one for Shang Ling'er. To distinguish them from each other, I used to separate them. " Bing-Er answered with certainty.

Sihan grasped the earrings in her hands and turned to call the maidservant who had been standing by the door. "Ju'er, come in."

The young maid gently pushed open the door and entered. She stood at the doorway and respectfully asked Sihan, "Miss, what orders do you have?"

"Young Master Bu has come to my Fang family to settle down." Sihan calmly instructed Ju'er.

Ju'er turned around and left. Before long, Liang Yuqi had rushed to Sihan's room.

When Bing'er saw Liang Yuqi, she couldn't help but sigh at the strength of the cell, and how in such a short period of time, it had actually completely changed a person. Liang Yuqi was wearing a brown robe, and her long black hair was tied up high in a bun.
