Yue Luoxue raised her eyebrows, this Geng Qing was truly a good at investigating cases, what fast movements! He had just arrived from the west side of the building this morning, yet she had already started investigating cases without stopping.

"Send him in." Nalan Rongxuan's voice came out. His black and white eyes turned, since he had nothing better to do, why not try to test this legendary Geng Qing out?

Yue Luoxue lowered her footsteps, and quietly went into the flower garden. Right now, her consciousness was extremely sharp, even if she was not near the study room, she could still hear the sounds inside clearly.

"Young master Dongfang, may I ask where you saved that servant?" Geng Qing wore a set of long green-grey clothes, which had been washed until they were slightly white. It was clear that the life of a demoted person wasn't too luxurious.

Dongfang Chen was feeling depressed, he waved his fan as he crossed his legs and lazily said: "The borders of the Silvermoon Kingdom."

"Then how can this servant explain the matter between the Crown Prince's prince and the Kingdom of Silver Moon's Imperial Advisor?" Geng Qing stared intently at Dongfang Chen's face, unwilling to let any changes in his expression go away.

Dongfang Chen squinted his eyes and impatiently repeated what happened with the servant. He didn't know that the servant was fake from the start, so he naturally didn't have any flaws when he said it.

However, Geng Qing did not seem to believe him. After asking a few more questions, he did not say anything else, but stood up and prepared to take his leave.

Nalan Rongxuan said indifferently: "Has Master found anything suspicious?"

Geng Qing fixed his gaze on Nalan Rongxuan with a complicated gaze: "The case has not been cleared up yet, please forgive me for not saying more."

"What's there to be afraid of? He's already dead." Dongfang Chen lazily leaned against the back of the chair. This Nalan Rongxuan had quite a high evaluation of Geng Qing, he thought that he did not have much ability. Seeing him today, it was no different.

"The blood of the deceased was scarlet red, and it was congealed into a lump. Although the true cause of death was the acute poison of the Southern Frontier, before this, there were also people who made him consume other medicines." Geng Qing's gaze was dark and unclear, he was not dissatisfied with Dongfang Chen's disdain, but his face was filled with suspicion.

"What do you mean?" Dongfang Chen paused. Oh, could it be that this Geng Qing saw that there was something wrong with that servant's identity?

"May I ask when Young Master rescued that manservant?" Geng Qing laughed in disdain. To him, corpses were the best evidence, and sometimes, there were even more corpses than living people.

"I saved him the day before yesterday." When he arrived at the Silvermoon Kingdom, it took him a few days to find any traces of Dongfang Chen. If the servant didn't hide himself too well, he wouldn't have believed that he was the follower of the Silvermoon Imperial Advisor.

"Judging from the blood agglomeration, the first time the servant took a special medicine should be a week ago." Geng Qing looked at Nalan Rongxuan meaningfully, cupped his hands, bowed, and then left the study.

Yue Luoxue saw Geng Qing's skinny figure rushing over to him, his eyes rolled around as he pushed open the door and entered Nalan Rongxuan's study.

Dongfang Chen's face was filled with displeasure, but just as he was about to speak, Nalan Rongxuan opened his mouth first: "Did you all hear that?"

"Did he discover something wrong with the attendant's identity?" With regards to Nalan Rongxuan's ability, Yue Luoxue did not doubt it at all. He had a lot of capable subordinates, and since she had changed the appearance of others, she would definitely not be exposed so easily.

"I just suspect that he can't find any evidence."

Although he was sure that there would not be any flaws in this matter, Nalan Rongxuan still appreciated Geng Qing's autopsy ability. The reason he was testing Dongfang Chen was probably because he already had his suspicions.

However, the pill that could change a person's appearance had always been a legend. Even with Geng Qing's vast experience, he still wouldn't dare to make such a conclusion. After all … It sounded quite shocking.

"Just now, I heard him say … That manservant seems to have the poison of Southern Frontier on her body? " Yue Luoxue took a deep breath. Could it be that the person who killed them last night was related to Southern Frontier as well?

"Right." Nalan Rongxuan seemed to be deep in thought. He had the nagging feeling that there was an unfathomable connection between him and the Southern Frontier, but he was unable to ascertain what this nexus was.

Yue Luoxue slightly narrowed her eyes. Geng Qing had said that it was due to the extremely toxic Southern Frontier, but he did not personally verify the claim. Yue Luoxue still harbored some doubts: "Is there any way to get that servant's blood?"

The place where the manservant was imprisoned was the Sky Prison. He should have paid more attention to safety and food, but he still died. Furthermore, it was poisoned. No matter how one looked at it, it was still inconceivable.

But... It would be different if he planted the Gu!

Southern Frontier's voodoo Gu technique was always exquisite and did not need to be in close proximity. Furthermore, the Gu could utilize anything and the person who implanted the parasite could achieve any effect, so there were no clues that could be traced.

"You suspect …" Nalan Rongxuan quickly understood what Yue Luoxue was suspecting. Indeed, the possibility of it being poisoned was not high.

"Yes sir!" Yue Luoxue nodded her head, Geng Qing could naturally feel the difference after examining the corpse, but he was afraid that as an outsider, he might not even be able to tell if it was a parasite or poison.

"Let me think of a way." Nalan Rongxuan's expression became serious, and his Southern Frontier, planted a parasite … These two things sound worth pursuing. After all, he still had the Red Lotus Fire Gu in his body. Perhaps it was done by the same person?

It was just as Geng Qing had said, the blood was bluish-black, and there did seem to be symptoms of poison on the surface. Furthermore, the degree of condensation on the blood did not match the time of his death, so it was obvious that he had taken other drugs beforehand.

"Little Qian, what did you discover …" Yue Luoxue stared at the cup of black blood in a daze for a long time, and in the end could only turn to some angry item.

"Humph ~" the Thousand Revolution Worm Poison coldly snorted. Every time it was used, it would speak nicely and kick it away after using it. It did not even give him a Yan Ling Pill. It did not want to help.

Nalan Rongxuan saw that Yue Luoxue did not say anything, and spoke: "Luoxue, did you find anything?"

"I was thinking." Yue Luoxue looked embarrassed. Damn, there are so many different kinds of Gu in the world, how could she recognize them all.

"Tsk, now you know how amazing I am." The Thousand Revolution Worm Poison crossed its legs and had a smug look on its face. It was a Thousand Revolution Worm Poison that knew both astronomy and geography, and the most brilliant of all Thousand Revolution Worm Poison.

"I said, don't tell me you don't know either?" Yue Luoxue looked at its smug look and took a deep breath. Hmph, this guy is really narcissistic.

The Thousand Revolution Worm Poison rolled her eyes: "Who doesn't know, it's just the Black Eerie Swamp. Do you think I'm as uncultured as you?"

He had the Thousand Chance treasure, alright? This kind of superficial problem was not difficult at all.

Yue Luoxue looked like a toddler, as she dipped her hand in the black blood and felt it carefully. Her brows furrowed slightly: "Oh, Black Underworld Gu, what's that?"
