"This is what the little prince meant, and the cold will definitely be carried out as scheduled, so if you want to save people, you have to hurry up."

Hongliu winked at Yan Yu and asked again, "Our Demon Clan's Horse Master, do you have any plans?" ”

Although Hongliu told Yan Yu very important information, she did not gain all of Yan Yu's trust.

After all, Hongliu is not his person, her will is still focused on the Demon Domain, and she doesn't care much about the life or death of several humans, as long as Yun Nishang is fine.

Yan Yu got up directly and said to Hongliu: "Remove the ban." ”

Hongliu didn't ask much, and took the ban back casually.

"Tomorrow at noon, don't eat."

Yan Yu left such a sentence and walked out of Hongliu's room quickly.

Seeing Yan Yu leave, Hongliu licked her lips and said to herself with interest, "What will happen tomorrow?" It's really exciting. ”

……

Early the next morning.

Yan Yu woke up Master Cao and Xiao Xuan'er, and went directly to the medicinal herb garden of the Frost Prison to search for materials for making poisons and antidotes.

Master Cao originally had the Cangshan River Sea Chart, but in order to develop the Killing Immortal Gate, Master Cao left the Cangshan River Sea Chart in the Killing Immortal Gate.

In the medicinal herb garden of Mourning Prison, there are not many varieties of medicinal herbs, but fortunately, Master Cao has a lot of rare and exotic herbs on him, and after a morning of busy work, he finally got all the materials.

On the way, Yan Yu also told Master Cao and Xiao Xuan'er what would happen tonight.

Time became urgent, everything had to be accelerated, Yan Yu thought that everyone could stay in the Frost Prison for a few more days, and then observe the form.

When it was close to noon, Master Cao had already successfully refined the poison!

Not only that, but Master Cao also deliberately made a few more "medicinal meals" according to Yan Yu's intentions, which were specially prepared for the robbery of Zhenwu and the cold of the sky!

These specially made medicinal diets are highly poisonous, even if Da Luo Jinxian eats them, I'm afraid that I will have to faint for a while!

"Xuan'er, you are looking for an opportunity in the kitchen to drug the people in the whole Mourning Frost Prison, Lao Cao, you can go with me to the Mourning Frost Tower again!"

Yan Yu and Master Cao informed the subordinates of the Frost Mourning Tower, and after a while, someone came to lead the two into the Frost Mourning Tower.

All the way to the fourth layer, Yan Yu directly shot and knocked all the subordinates unconscious.

The door opened, and Fluttershy, his wife, said to Master Cao with a concerned face, "What's going on?" ”

"Lao Cao, you explain to her, I'll go upstairs."

After Yan Yu finished speaking, he directly broke the ban and went up to the fifth layer.

Master Cao quickly pushes Fluttershy into the house and says, "It's nothing, let's continue to do yoga......"

……

On the fifth floor of the Frost Mourning Tower, Yan Yu walked up quickly.

Yun Dizang was in chains, and when he saw Yan Yu appear, he was a little surprised: "You kid really dare to come back?" ”

"You are my father-in-law, if I save Nishang and don't save you, how will I live with Nishang in the future?"

Yan Yu stepped forward and summoned the Tai'a Sword, slashing at the iron cage with a sword.

I don't know what this iron cage is made of, and there is no way to take it!

Yun Dizang shook his head and said, "It's useless, this iron cage and iron lock, if it's just an ordinary material, how can it trap me?" ”。

"How can I get you out?" Yan Yu asked anxiously, there wasn't much time left for him.

"The only key, carried by Sha Tianhan, you can't get it."
