"Because this old man is the imperial physician of the Eagle Nation's royal family. After retiring, he did not leave the imperial capital but stayed there, secretly serving the Eagle Nation's royal family, specializing in clandestine matters!"
"Furthermore, there are rumors that he knows the secret arts of the Eagle Nation's royal family! The ancient villa ahead is Deson's residence. If we discover that he indeed knows the secret arts of the Eagle Nation's royal family, then we can confirm he is the murderer!" Jinmen said.
Upon hearing this, Jiang Yi immediately understood that Cuixi and Jinmen only suspected Deson was the murderer but had no proof.
"Since you've already found a clue, you can investigate yourselves. Why did you call me? Aren't you afraid I'll steal your credit?" Jiang Yi said with a smile.
"Credit is not important. The most crucial thing is to clarify this matter!"
"Besides, my adoptive father instructed the three of us to investigate this case together, so we must investigate as a team!" Jinmen said.
Cuixi, however, remained silent.
Hearing this, Jiang Yi couldn't help but chuckle.
Jinmen wasn't telling the truth. He was afraid that he and Cuixi couldn't handle it, just like before when they almost lost their lives, so he dared not act rashly and had to bring Jiang Yi along.
With Jiang Yi present, they felt a sense of security.
Deson, who knew the secret arts of the Eagle Nation's royal family, was not someone Jinmen and Cuixi could handle.
Jinmen and Cuixi, to save face, did not state this directly and merely offered a casual excuse.
Jiang Yi did not expose them. He looked up at the old villa ahead, surveyed it, and then let out a cold laugh.
"Did you discover something?" Cuixi asked urgently.
Jinmen also looked at Jiang Yi.
"Fortunately, you didn't rush in. Otherwise, no matter how skilled you are, you would have lost your lives inside!"
"Around this old villa, have you noticed a very thin black gas pervading the air?" Jiang Yi asked.
Hearing this, Cuixi and Jinmen's eyes widened, and they looked carefully.
Indeed, they noticed some black mist surrounding the villa. Because the surroundings of the villa were densely planted with tall trees, the mist was blocked. If they hadn't looked closely, they wouldn't have noticed it at all!
"This is too bizarre. What is this? We only see this kind of black mist on television and in movies. It doesn't exist in real life!" Cuixi frowned and said.
"You are mistaken. This sort of thing exists in reality. This black mist is called Poisonous Fog. In some remote virgin forests, there are many such poisonous fogs!"
"Poisonous Fog is actually the result of various poisonous plants and creatures releasing toxic gases into the air in a specific environment. When multiple toxic gases interact, a chemical and physical reaction occurs, generating this bizarre black mist, which is known as Poisonous Fog in Traditional Chinese Medicine!"
"This Poisonous Fog is extremely potent. Anyone or any animal that gets too close will die instantly from poisoning. No animal dares to approach; anyone who approaches will surely die!" Jiang Yi explained.
Cuixi and Jinmen listened, their eyes almost popping out. They had truly broadened their horizons, seeing such a terrifying thing for the first time with their own eyes.
"You said earlier that this old villa is Deson's territory. If I'm not mistaken, Deson is a master of poisons, and the much-talked-about secret arts of the Eagle Nation are probably just methods of poisoning!"
"The fact that Deson can grow poisonous plants himself and create a Poisonous Fog indicates that his poisoning skills have reached the pinnacle of perfection!" Jiang Yi stated.
Upon hearing this, Cuixi and Jinmen's expressions became grave.
"Can you handle Deson?" Cuixi asked urgently, "If you can't, I'll call back and get reinforcements immediately."
"Don't worry. I don't take Deson's poisoning skills seriously at all. Later, you will come in with me and follow my instructions. Don't touch anything or wander off randomly!" Jiang Yi said. He then took out two pills and threw them to Cuixi and Jinmen, saying, "These are antidote pills to prevent poisoning. I developed them in the lab earlier."
Cuixi and Jinmen swallowed them without hesitation.
"Let's go! Let's go in and catch Deson!" Jiang Yi said, then walked directly towards the main entrance of the villa.
Jinmen and Cuixi hurried to follow.
The villa's main entrance was also within the range of the Poisonous Fog. If one looked closely, they would notice numerous skeletons of birds, wild dogs, and other animals at the entrance and around the corners of the walls.
Some of these skeletons had already turned into white bones, while others were just beginning to rot, emitting a truly foul odor.
Seeing these skeletons, Jinmen and Cuixi felt a chill down their spines, their backs growing cold.
Although it was daytime, the villa was surrounded by towering trees, blocking out the sunlight. No sunlight reached the villa, making it look like a terrifying haunted house.
"Creak..."
Jiang Yi directly raised his hand and pushed open the villa's main door.
Immediately, a pungent, foul odor gushed out from inside.
Jiang Yi quickly covered his nose and mouth with his hand, forgetting to tell Jinmen and Cuixi. The two were immediately choked, their eyes watering, and they coughed incessantly, feeling as if they would cough up their internal organs.
"Pinch your Hukou point!" Jiang Yi instructed.
Upon hearing this, Jinmen and Cuixi pinched the Hukou points on their wrists. Instantly, their coughing stopped as if nothing had happened.
"Jiang Yi, you are truly amazing. You truly live up to the reputation of a divine physician from the Huaxia Nation!" Jinmen praised.
"These skills are nothing!" Jiang Yi raised an eyebrow and then said, "Let's hurry inside! We must seize the time to capture Deson and not let him escape!"
After speaking, Jiang Yi strode into the villa!
Jinmen and Cuixi followed closely behind.
Upon reaching the villa's courtyard, they found it densely packed with many wooden barrels.
On top of each barrel grew a very strange flower, which looked dazzling and alluring, yet always gave a fatal impression.
The flowers on these barrels were of various shapes and colors.
"Jiang Yi, are those Poisonous Fogs you mentioned produced by these poisonous plants when they volatilize?" Cuixi couldn't help but ask.
"That's right!" Jiang Yi nodded. "To produce Poisonous Fog from poisonous plants and creatures, you need over three hundred types of poisonous flora and fauna. Only when these are gathered together can Poisonous Fog be generated."
"Poisonous Fog has a certain range, existing only within thirty meters of the poisonous plants and creatures. Once you exceed this distance, the Poisonous Fog dissipates!"
Jiang Yi learned about Poisonous Fog from his master.
In the past, Jiang Yi thought such things didn't exist. Not until now did Jiang Yi believe that such a thing truly existed in the world.
