It was said that women only had long hair and short knowledge. It seemed like the current situation would not work.

"Royal granddaughter consort is indeed powerful, this old official admires you!" Chen corona extended a hand to salute.

This woman was always able to surprise him time and time again. He would never know where she ended up. It was like a jar of century-old wine. Every mouthful she took gave him a new feeling.

"This is Green Slaughtering Powder, not Lifesteal Powder. Chen corona, I ask you, do you know why the person who poisoned you used these two similar poisons?"

"This …" Chen Guan thought for a moment and sighed, "This old subject does not know, I hope Royal granddaughter consort can explain."

Shen Kouqing laughed: "Lifestealer pills are common, but Qingqing Powder is not, and the two symptoms are exactly the same. If an expert did not carefully examine the body, and did not find out, if Imperial Physician Li came to treat Sixth Prince and suddenly died in less than four hours, if it was the Sixth Prince who did it, why did he choose to stay in his own residence, to prevent others from suspecting him?"

These last few words, Shen Kouqing said it all to Song Yichen.

Yesterday, when they returned, Song Yichen had buried his head into the study and did not come out. Without even thinking, it was obvious that he was investigating the matter of poisoning the emperor.

She could not openly tell Song Yichen that the poison was administered by Song Yuanhui, but it was still possible to draw it in.

The deep black pupils tightly locked onto Shen Kouqing, and Song Yichen tried to think of something.

But he was disappointed. Shen Kouqing looked at him with a beaming smile, her eyes as clear as spring water.

"Where did the Murderous Green Powder come from?" He finally spoke.

Shen Kouqing shrugged. "I don't know."

"You really don't know?" Song Yichen did not believe it.

Shen Kouqing raised her head and looked at him. For some reason, she felt that Song Yichen's emotions were off.

But she couldn't understand, Song Yuanling wasn't the person who poisoned him in the first place, wasn't it a good thing to help him wash away his grievances?

After thinking for a moment, she still persisted with her original answer. "I, Huang Tidemark, don't know who the murderer is, but I can tell you that only one person in the capital possesses the Murderous Green Powder. Because …"

She purposely wanted to say something but hesitated. Waiting until Song Yichen became curious, she didn't say anything.

Smiling, Shen Kouqing bowed and left.

She was in a great mood, destroying every single of Song Yuanling's plans and pulling everyone back from the brink of death, she was truly very happy.

Song Yichen looked at her back and thought for a long time.

After Shen Kouqing left, Song Yuanling's Duke Palaces were thoroughly searched. Let alone Killings of the Green, there weren't even any Life Snatching Powder. Adding on the various coincidences, it was very clear that the culprit wasn't him.

But, who was it?

It was already late in the night, yet Shen Kouqing still hadn't slept. Song Yichen had already been back for a long time, yet he was still locked in his study, busy with something unknown.

Sitting by the window and looking at the light in the study, Shen Kouqing held her wine cup tightly.

After a long time, he laughed softly.

Even after such a long time had passed, she was still unable to calm her heart. Thinking about how she looked before she died, hatred surged through her heart like raging waves.

Shen Kouqing hated that she couldn't immediately tell Song Yichen the truth, but she knew that Song Yichen would never believe it.

Forget it, forget it …

The light suddenly flickered, and a figure quietly snuck in. Shen Kouqing sneered: "To flip the windows in your own house, it's like being a thief. There's no need for that."

Song Yichen put his hand on her shoulder.

"Who the hell are you?"

Shen Kouqing was startled, she turned his head and looked at Song Yichen.

His face was serious and his eyes were extremely cold. He was completely unlike his usual passionate self.

She smiled. "Who do you think I should be? Of course I'm your proper wife."

Song Yichen said sarcastically, "If you want to be a good person, you have to hide your tail. Kou Qing never does that."

"Whatever you say."

Shen Kouqing was not in a good mood, she didn't want to say anything.

Raising his head to drink another mouthful of wine, Shen Kouqing nearly choked and coughed a few times.

"What exactly do you want to ask me?"

"How much do you know about the Ninth Imperial Uncle?" Shen Kouqing shook his head: "I don't know anything, I just happened to be ill, and had a very long dream, without end, with death as the end. Fortunately, I have not reached the end, I am still alive."

She looked out the window at the bright moonlight, her eyes were misty and sad for a moment. She raised the wine cup in her hand for a long time but still couldn't drink a mouthful, so she just threw it to the side.

"Never mind, even if I told you, you wouldn't understand."

Shen Kouqing stood up and walked to the window, then added, "As long as you know, I won't harm you, and I won't harm the person you love, that's enough."

"Where's the Ninth Imperial Uncle?" Song Yichen suddenly said.

Shen Kouqing paused, "Of course not."

"I mean, how you feel about him."

Song Yichen walked towards Shen Kouqing, "What did you do to him?"

So it was this.

Shen Kouqing thought, and just as she was about to speak, she was stopped by Song Yichen.

In the darkness, his pupils were sparkling, like a stray cat in the dark, vigilantly watching every little movement in its surroundings.

"I …" Shen Kouqing opened her mouth, but she did not know what to say.

She didn't know if she still loved Song Yuanhui, but she hated him.

The clear train of thought had blurred once again. Shen Kouqing looked at him with an overbearing gaze, but was unable to say anything.

"If you still love Ninth Imperial Uncle, why marry me, and why expose him?"

Shen Kouqing suddenly froze: "So you already knew."

Song Yichen did not hide anything as well, "I will do as you say and go investigate the Slaughterer Powder. Only the Ninth Imperial Uncle has it.

If Shen Kouqing didn't provide some clues, Song Yuanling would be the scapegoat, but, didn't Shen Kouqing like Song Yuanhui?

He really could not understand, in these few days, one question after another piled up in his mind. He could not wrap his head around it, and every time he questioned Shen Kouqing, she would always have a smile that was not a smile.

Most importantly, the spy that was planted beside Shen Kouqing had come to report, saying that Song Yuanhui and Shen Kouqing had met in private, and the two of them were pulling each other, talking and laughing, what kind of logic was that!

A faint smell of vinegar was slowly fermenting in Song Yichen's heart.

Shen Kouqing looked at the somewhat baffled Song Yichen, and didn't know what to say.

After a long while, she sighed: "You don't need to care about this matter, I know what I'm doing, as for Song Yuanhui … I can tell you, there's no place for him in my heart. "
