Suddenly, the sound of footsteps came from behind him. Song Yuanhui turned his head quickly and saw a servant running over, and said respectfully: His Highness the Ninth Prince, the Marquis of Wu Ling is here to invite you.

Song Yuanhui nodded and let the servant lead the way.

She really could not stay any longer. She comforted Shen Koudan a little and then found an excuse to leave.

Just as she left, Song Yuanhui came in.

No one knew what the two of them discussed, but when Song Yuanhui came out, his face looked much better.

Shen Kouqing could not help but exclaim.

A person would only care about you if they had value. Just like the Marquis of Wu Ling, his previous life was used to his full ability by Song Yuanhui, but what about the result?

Shen Kouqing sighed.

When she returned to her residence, the sky had already darkened. The blurry darkness was like smoke and fog, enveloping both the emperor's eldest grandson's residence and Shen Kouqing's heart.

Just as she entered the residence, she heard the butler say that she found the person who poisoned the Emperor. It was Sixth Prince Song Yuanling.

Shen Kouqing's heart thumped, how is this possible? The one who poisoned is clearly Song Yuanhui, what does it have to do with Song Yuanling!

He then found out that, originally, Imperial Physician Li had gone to treat Song Yuanling's illness this afternoon but accidentally died in Song Yuanling's residence. Coincidentally, there was a piece of news that came from the Imperial Palace that Imperial Physician Li had touched it before when the bowl of Swallow's nest glass was served.

Song Yichen had already gone to Song Yuanling's residence. Shen Kouqing had only just returned to Emperor's Zhangsun residence, and then immediately went back to Sixth Prince's residence.

Shen Kouqing had decided that since the heavens had let her live anew, she could not allow any good person to be misunderstood and wronged. Moreover, this matter had nothing to do with Song Yuanling.

And at this time, in Sixth Prince Mansion.

Song Yuanling stood there in the hall in a daze. In front of him was Imperial Physician Li's corpse, the coroner was carefully examining it, while Song Yichen was at the side asking for details, but did not sense anything strange.

Song Yuanling's face had already turned ashen, and he stood there blankly without moving for more than two hours.

He was really scared to death. Who would be able to withstand a sudden death in front of them?

"Chen corona, do you have any results?" Song Yichen could not help but ask.

Chen corona frowned, as though this was a thorny problem. Hearing Song Yichen's question, he sighed: "Vicious, so vicious!"

He stood up and pulled at Imperial Physician Li's stiff hand for Song Yichen to see, "Royal Elder, please look. Imperial Physician Li's fingernails are black, it's not because there's mud inside them, but because he's poisoned."

"Poisoned?" Song Yichen exclaimed.

"It's not me!" "It's not me!" Song Yuanling suddenly jumped up, and waved his hand in fear, "Nephew Huang, you're going to help Sixth royal uncle, it's really none of my business, it's really …"

Song Yuanling did indeed have ambitions for the throne, and he had also had the beautiful dream of becoming the emperor, but he was naturally timid. He thought of ten thousand ways to usurp the throne, but none of them came true.

However, he didn't expect that when people were sitting at home, the pot would come down from the sky. Even if he jumped into the Yellow River now, he wouldn't be able to wash it off.

Song Yichen frowned, "Royal Uncle, do not worry, wait for the coroner to finish his examination."

"It's not me. It's really not me. It's really not me …" Song Yuanling was already scared to the point of incoherent speech, he half knelt on the ground shivering.

There was no way Song Yichen could do it, he could only have the butler take him down, and then ask an imperial physician to prescribe some Spirit Calming Medicine for him.

"Chen corona, please continue."

Chen corona opened Imperial Physician Li's eyes. Doctor Li's pupils became brighter in the darkness and his hair stood on end due to the gaze. Even the countless Chen corona who had examined corpses were shocked, but Song Yichen did not seem to feel any discomfort.

The Emperor's eldest grandson, everyone knows that after a person dies, their pupils will dilate, but look, Doctor Li's pupils aren't dilated, but he is indeed dead. This is the result of the poison, and the blood that condenses in the brain will cause the meridians in the eyes to become blocked.

"And here." Chen corona raised Imperial Physician Li's stiff arms and spoke frankly: "After a person dies, their corpse will not turn stiff in a short period of time, but soften. It will turn stiff after a period of time, then soften again, and their internal organs will start to rot. However, Imperial Physician Li, on the other hand, has only been four hours, and their bodies are already incomparably stiff."

He pondered for a moment and speculated, "This should be a life-reaping pill."

"Chen corona's words are wrong!"

A female voice came out. Song Yichen turned his head and saw Shen Kouqing jogging in.

After tormenting himself for an entire day, Shen Kouqing was finally exhausted. However, she still persisted on, all for the sake of not letting Song Yuanhui's scheme succeed.

If she came later, Song Yuanling would become even more suspicious.

"Why are you here?" Song Yichen went forward to support her, and seeing that Shen Kouqing's expression was a little ugly, he advised: "This place is not suitable for a weak girl like you, quickly go back!"

"Wait." Chen corona suddenly said, "Royal granddaughter consort, your words just now were wrong. Why is that so?"

Shen Kouqing smiled faintly: "The symptoms that you have speculated are not wrong, it's just that this poison is not Lifestealer Powder, but Murderous Green Powder."

Seeing how serious Shen Kouqing was, Chen corona was shaken for a moment, but he quickly rejected the idea in his heart. Although he still looked respectful on the surface, he was actually very dissatisfied.

However, Song Yichen asked: "How did you know?"

"Don't worry about how I know." Shen Kouqing turned to look at the Chen corona, "Chen corona should know that we cannot come across the Yin Yang Grass. The moment we do, it will release a bad smell that will make us unconscious, and the Lifesteal Powder will not, as for whether it is Life Slaughtering Powder or not, we will know after giving it a try."

The Chen corona nodded.

Song Yichen instructed, and the butler immediately went to the medicine hall to bring the Yin Yang Grass.

The Yin Yang Grass may have a strange name, but it was indeed a great medicine for curing illnesses. Combined with the Green Annihilation Powder, it was like a bewitching medicine, but when combined with other herbs, it was a great medicine for treating illnesses.

Shen Kouqing cut open Imperial Physician Li's arm and let out a bit of blood, then grinded the Yin Yang Grass in, causing the three of them to retreat, leaving behind a few kittens.

After waiting for the time it took for an incense stick to burn, the cats suddenly jumped up and down.

Shen Kouqing, Song Yichen and Chen corona hid outside the door and watched quietly, when they saw what happened, they were all stunned. When he regained his senses, she was full of respect for Shen Kouqing!
