The people of Beiyuan Town didn't know that the battle outside was over, and they were afraid of being affected, so even if it was calm for more than ten minutes, no one dared to show their heads to check.

"The black armor has all been scattered, and no one will report to Sha Tianhan, but I believe that what happened in Beiyuan Town, Cha Tianhan will not know it soon."

Yan Yu made a decision: "Without further ado, let's go to the Boundless Frozen Sea and enter the Frost Prison as soon as possible." ”

Xiao Xuan'er and Master Cao naturally supported this decision.

There was nothing to clean up in the tavern, and the three of them took off directly into the air and flew north.

"Yan Yu, now you know the exact location of the Frost Prison, right?" On the way, Xiao Xuan'er couldn't help but ask.

Yan Yu nodded: "The Mourning Frost Prison is more than a thousand kilometers northwest of Beiyuan Town. ”

"Northwest?" Master Cao was stunned for a moment, and looked up to identify the direction, "But we're flying in the northeast direction now!" ”

"We're going to the northeast."

Master Cao didn't understand: "Why, aren't we going to Mourning Frost Prison?" ”

"Geng Xiu has just escaped from the Frost Prison, and the current Frost Prison must be as airtight as an iron bucket, let's go over now, I'm afraid we won't even be able to enter the gate."

Xiao Xuan'er was puzzled: "Isn't there still Geng Xiu's memory?" How did Geng Xiu escape, how can we get in? ”

"Since Cha Tianhan has sent Black Armor to hunt down and kill Geng Xiu, it means that they have discovered Geng Xiu's escape, and Waishuang Prison is known as the most terrifying prison in the entire Demon Domain, how can they tolerate the loopholes that exist to escape all the time? I'm afraid that Geng Xiu has just escaped, and his escape route has already been made up by the Frost Prison. ”

After listening to Yan Yu's words, the two of them also knew that the Frost Prison was powerful, but Yan Yu still didn't explain why they wanted to go to the northeast.

Yan Yu didn't hang everyone's appetite either, and said directly:

"The reason why we are going to the Northeast is to find people."

"I learned from Geng Xiu's memory that Sha Tianhan's wife was seriously ill, and all the famous doctors in the north were helpless.

"According to the time calculation, this team should soon pass through the Howling Wind Valley in the north, what we have to do is to intercept those three famous doctors halfway, and then take their place and go to the Frost Prison."

Xiao Xuan'er was slightly surprised: "We want to pretend to be a famous doctor?" ”

"With Lao Cao here, there's nothing to worry about." Yan Yu said with a smile.

Master Cao does know how to practice medicine, and when the time comes to the Mourning Frost Prison, Yan Yu and Xiao Xuan'er only need to do it.

"Master of Dare, you brought me to the Chaos Demon Domain, are you waiting for me here?" Master Cao complained.

While he was dissatisfied, he was a little arrogant, after all, his ability finally came in handy.

"Lao Cao, there is a long way to go, turn around and pretend to be a famous doctor to arrive at the Sorrowful Frost Prison, and the lives of Xuan'er and I will be handed over to you." Yan Yu patted Master Cao's shoulder and said.

"Don't worry, it's all right!"

The distance of more than 1,000 kilometers is equivalent to crossing half of China, but with the flight speed of a few of them, it will only take half a day to arrive.

Half a day later, the sky was getting dark, and Yan Yu and the three of them also managed to reach the only way from the Demon Capital to the Frost Prison - Howling Wind Valley before the famous doctor.
