Soon, the Immortal Emperor Hall appeared in front of the two of them. None of them were in the mood to enter through the main entrance, so they jumped directly into the air inside.

Anyway, the Immortal Emperor Hall is also the prohibition of the Yuan Emperor Rank, and as the boss of the Yuan Zun Rank, they will not be cowardly.

The red spiritual power confinement cover next to the Jiangyue Pavilion was still there, but the people in the Jiangyue Pavilion were gone. Only on the small round platform in the center of the Jiangyue Pavilion was left the light blue* hairband that Wen Yaoyao habitually used to tie her hair.

"Tsk, that's a little tricky."

Gu Xiaoxuan flipped over and stared at the headband, and the alarm bell began to ring in her heart.

Because, she felt it, there was residual poison on this headband!

"Senior sister, why do you say this?"

Mu Zeyan still has too little knowledge of the field of poison, so he can't feel it.

"On the hairband left by Yaoyao, there is a small amount of residual poison. It should have been left by Yaoyao on purpose, so that we could find out! ”

Mu Zeyan looked at this headband with a complicated expression: "Then if that's the case, it's really tricky." ”

"It also seems to be a good thing, though."

Gu Xiaoxuan suddenly raised a confident smile and tucked the headband into his cuffs. This dose of poison is not a threat to her, so she is not afraid of getting into it.

"Isn't there a drug master around us? Wait for me to go to the Lanyuan Palace. ”

She was going to find her sister of the drug boss, Gu Mengyue, the lord of Siqin and the emperor of Lanyuan.

Because she alone is not enough to recognize this poison, let alone solve this poison.

"Senior brother, it seems that there are no other clues here, you should go and search the Lanyuan Continent first, and see you here in two hours, whether you find it or not." Gu Xiaoxuan had already arranged the order of things, and next, he just waited to do it step by step.

Maybe I'll be lucky today, and I'll be able to find it aimlessly.

Mu Zeyan believed in Gu Xiaoxuan's organizational ability, and flew away in response.

For now, this is the best way to do it.

Gu Xiaoxuan shook his head and carried light skills in the direction of the Lanyuan Palace.

Lanyuan Imperial Palace Zhaoyuan Hall.

"Sister, what's wrong? So anxious. Gu Mengyue's hand, which was still concocting poison, paused slightly, and looked at Gu Xiaoxuan, who was panting, with a suspicious expression.

Gu Xiaoxuan saw that the table was full of poison bottles, purple, blue, yellow, green...... Poisons of various colors even have gradients. The poison bottle also has an exclusive pendant engraved with the name of each poison to avoid confusion.

Gu Xiaoxuan looked at it again, eroding the heart poison * poisoning cold bone poison......

Her smile faded away.

"My sister. Are you the rhythm of poisoning people and not paying for their lives? ”

"No! I'm just idle, I just have nothing to do, mix a few bottles of poison and find someone to try the effect! ”

Gu Mengyue shook the bottle of poison in her hand and looked at Gu Xiaoxuan aggrievedly.

"Oh, why am I being led astray by you again, I have to get down to business!"

Gu Xiaoxuan patted her head and yelled while jumping to her feet.

Gu Mengyue's face was full of black lines.

Do you dare to blame me for forgetting your business? I don't know who talked about this topic first?

"What's the business to say, sister, don't jump your feet, it's ugly!"

"You're ugly. My nephew, the first disciple of the Immortal Emperor, Wen Yaoyao, was taken away today in the Jiangyue Pavilion of the Immortal Emperor's Palace. She left a hairband, there is a little residual poison on it, you can see, what kind of poison is this, is there a solution? ”

Gu Xiaoxuan took out the light blue* hairband from his sleeve and handed it to Gu Mengyue.

"Well, this poison is the blue poison on the table, called, Cold Bone Poison."
