"Master, how could they suddenly be poisoned? The two of them have rarely been out for three months! After knowing this result, Huo Xuan calmed down instead.

And Xiao Huohuo's angry eyes also sank, looking at Feng Caitian quietly.

"Not sudden poisoning, but chronic poisoning. Since we don't go out often, we must have something in our yard that shouldn't be there! As he spoke, Feng Caitian's eyes narrowed, sweeping every inch of the room.

Most of the things on the first floor have been replaced by Mother Hua, except for a few pieces of furniture that are not broken, all of which are newly made.

However, the day after these things were placed, she also went downstairs to taste the lotus porridge made of autumn leaves, and she didn't notice anything unusual at that time, but what was the problem?

You must know that the poison in Autumn Leaves and Liu Jin is a chronic poison called the fragrant tea dove, although it is extracted from the trunk of a fragrant tea tree, and it is not like the dove poison that sees blood and seals the throat, but it is also definitely a deadly poison.

On weekdays, if you smoke tea dove occasionally, you can still strengthen your body, but if you smoke it for a long time, your body will not feel abnormal, but when the toxins accumulated by the human body reach a certain amount, it will suddenly erupt. To put it simply, the symptoms of this poison are like cerebral hemorrhage, the onset is rapid, and if it does not occur, it will directly kill people.

Moreover, this fragrant dove also has a very wonderful effect, that is, it can make people instantly engorge the brain within ten seconds, and the heart is deprived of oxygen within five minutes; But after five minutes, the poison of this tea dove will disappear from the human body and evolve into another hemophilic poison that specializes in devouring nerves and meridians.

Therefore, if it weren't for the fact that she happened to see Autumn Leaf's poisonous hair in the attic just now, and sealed her heart in time, Autumn Leaf and Liu Jin would not have been able to save her at all. And it was difficult for her to find any clues from their corpses.

Suddenly, Feng Caitian's gaze stayed on the incense burner by the window.

"Has this thing been in front of the window?" Feng Caitian said in a deep voice.

"Yes, master," Huo Xuan nodded, recalling, "it was the day of your retreat, and the morning of our breakfast, and when you left, the autumn leaves lit the remaining incense again." She said that the air in the house would be a little better this way, and that you wouldn't smell any more when you came down for lunch.

But later, when it was close to noon, you said that you were going to retreat and let Akiba take the meal to the attic, and Akiba extinguished the incense burner and put it in front of the window. ”

"Any questions?" Xiao Huohuo asked suspiciously, and used spiritual power to pull the incense burner by the window with spiritual power.

"I don't know, just look at it!" Feng Caitian just asked casually, and he didn't really suspect that there was something wrong with the incense burner. After all, when I came down to drink porridge one morning, I also smelled the aroma of mint, refreshing and clean.

It's just that the moment Feng Caitian opened the lid of the furnace, he was furious.

"I see!" Feng Caitian slammed the incense burner in his hand to the ground and stood up with a bang.

Huo Xuan and Xiao Huohuo didn't expect Feng Caitian to suddenly come out like this, and suddenly made a big jump, "What's wrong?" ”

With a mutter, the two snakes turned their gaze to the ground sprinkled with incense ashes, and to the tumbling stove and lid.
