Mortals ask the immortals

Legend!

Duan Qing's heart tightened, and his face showed a look of great interest.

"Oh? What legend is it?"

Ou Yezi stopped what he was doing and recalled.

"When I first entered the Black Prison, I was caught by scavengers and sold to Tiandi City as a slave for a period of time. I helped do some odd jobs in the weapon refinery in Tiandi City."

"Once, I accidentally heard the old owner of the weapon refinery in Tiandi City say something."

"It is rumored that countless years ago, there was no way to get out of the Black Prison, and the Black Emperor did not set a rule of letting one person out every hundred years. Those who were imprisoned in the Black Prison could only be trapped in the Black Prison for life."

"The Black Prison at that time can be said to be a real purgatory on earth, and the people inside could not see any hope."

"But for some reason, one day, all the people in the Black Prison suddenly disappeared, not one was left!"

All disappeared!

Duan Qing was shocked and asked: "Why did all the people in the Black Prison disappear? Did they die or did they all escape?"

Ou Yezi shook his head blankly: "I don't know. Legend has it that this happened before the war between the Sui Clan and the Fairy Alliance, at least a million years ago. It was too long ago. Who knows what happened back then!"

Before the war between the Sui Clan and the Fairy Alliance, a million years ago!

Duan Qing fell into deep thought.

According to his and Wuhuji's inference, the corpse of the Sui Clan with the inner mustard in the Zhenji Palace was very old and should have died in the early days of the war.

And before the war started, everyone in the Black Prison had disappeared!

The time span between the two should not be large.

Is it possible that the Sui Clan with the inner mustard who died in the Zhenji Palace was the one who escaped from the Black Prison, but later died in the war, so he carried the secret of leaving the Black Prison with him!

But Ou Yezi said that everyone in the Black Prison disappeared mysteriously at that time.

Judging from the number of people in the Black Prison today, even if there were no human and demon tribes in the Black Prison at that time, there must have been a lot of people.

If so many people had all left the Black Prison, wouldn't there be ways to leave the Black Prison everywhere?

It seems that there must be something else going on!

Thinking of this, Duan Qing sighed deeply.

Even Ou Yezi, who had been trapped in the Black Prison for so many years, didn't know what other ways there were to leave the Black Prison. Does the bluestone really hide the way to leave the Black Prison?

Or... take out the bluestone and show it to Ou Yezi?

As soon as this idea came out, Duan Qing immediately rejected it.

The fewer people who know about this matter, the better, so as to avoid unnecessary trouble.

When he was really sure that the bluestone could allow people to leave the Black Prison, he didn't mind taking Ou Yezi with him, but now... for the sake of caution, it's best not to let others know about the bluestone.

Duan Qing and Ou Yezi spent a lot of effort and finally cleaned up the entire refining workshop.

Afterwards, Duan Qing found an excuse to refine a weapon and locked himself in the refining room, and then activated the void hat and entered the virtual space.

As soon as he entered the virtual space, Duan Qing couldn't wait to take out the bluestone slabs he got that year from the storage bracelet.

There were a lot of bluestone slabs, more than 10,000 pieces. Duan Qing took them all out and arranged them on the ground around him, examining them carefully one by one.

On each bluestone slab, there was a number from one to 11,200, without any repetition, and a different line.

Apart from the numbers and lines, there was nothing else on the bluestone slabs, and there was nothing special about them.

It seemed that the key was in these numbers and lines.

Duan Qing pondered for a long time, but still had no clue. He had no choice but to put away all the bluestone slabs, and then cultivated the Tianlei Bamboo for a while before leaving the virtual space.

After refining a blank in the refining room, Duan Qing left the refining room again and prepared to go to Nan Ying.

The second return of the main force of Xianling City should be all members, and Hu Youwei and others should be among them. He wanted to find Nan Ying and arrange for himself to meet Hu Youwei and others.

After all, they had been teammates in the patrol team for several years, so they had some feelings for each other.

However, when Duan Qing walked to the main hall of the weapon refining workshop, he saw three people standing at the door of the main hall. Who else could it be but Hu Youwei and his three friends?

"Brother Hu, Fellow Daoist Wu, Fellow Daoist Huang!"

Duan Qing smiled and walked up to them when he saw them.

Hu Youwei heard Duan Qing's voice and a happy smile immediately appeared on his face.

"Brother Duan, have you finished refining weapons?"

"Haha, Fellow Daoist Duan, you are indeed in the Black Prison, but you made the three of us wait so long!"

"I really didn't expect that Fellow Daoist Duan could also refine weapons, but it was so hard for us to keep it a secret."

The fat guys Wu Ma and Huang Tianye also laughed and teased.

Seeing the three people so enthusiastic, Duan Qing was relieved and a little surprised.

He looked for Hu Youwei and his three friends mainly to explain what happened before. After all, Hu Youwei and his friends, like Nan Ying, also saw him burning his body for the third time at the edge of the dark domain, and misunderstandings were inevitable.

But he didn't expect that the three of them had no grudges against him at all.

As if he had guessed Duan Qing's thoughts, Hu Youwei smiled and explained: "Don't think too much, brother Duan. Lord Nan has already explained your matter to us."

Duan Qing nodded: "Haha, that's great."

Although I don't know how Nan Ying told Hu Youwei and the other two, it seems that the effect is quite good now.

"By the way, I heard from Lord Nan that Brother Hu and you followed the city lord to collect sweet rain. How was the harvest this time?" Duan Qing asked casually.

When Duan Qing mentioned the sweet rain, Hu Youwei immediately looked bitter: "Hey, don't mention it!"

"It was pretty good at first, but Xianling City was attacked by scavengers twice in a row, and finally we had to transfer all the people back."

...

Then, the few people talked about the past for a long time, and Hu Youwei and the other two left, while Duan Qing returned to his room to rest.

Half a month passed in a flash.

During this half month, Xianling City was basically rebuilt with the efforts of many cultivators, and all affairs in the city resumed operation.

Since most of the people in the weapon refining workshop were captured after the city was broken, there was a shortage of manpower.

As a result, Duan Qing was very busy. He had to do the work of several people before. Every day he was either refining or on the way to refine, and basically had no time to do other things.

Fortunately, this situation has finally improved in the past two days.

Since the weapon refinery was so short of manpower, after the reconstruction of Xianling City was completed, the city lord personally recruited a group of monks with a certain level of weapon refinement in the city to supplement the weapon refinery, which finally solved the urgent needs of Ou Yezi and Duan Qing.

In fact, this situation is not limited to the weapon refinery, but also other places in the city such as the alchemy workshop.

That day, Duan Qing had just finished the work at hand when he heard a shout outside the weapon refinery.

"Is Duan Qing here?"
