Two months passed in a flash, and as Cheng Ling expected, when the pointer completed a cycle, the two doors in the hall reopened.

This time, everyone was relieved. Although the immortal aura in the secret room was not as good as some powerful cultivation secret realms, it was greatly compensated for in terms of time, and everyone's cultivation was slightly improved, and a smile appeared on everyone's face.

The only outlier is Ye Zhining, as soon as the two doors opened, he couldn't wait to say to Cheng Ling: "Cheng Ling, let's go out quickly and see if the time outside has only passed a month as you speculated." ”

Jin Muchen smiled and said: "Girl, the time has passed twice as much, it is easy to distinguish it, we don't feel a trace of the loss of Shouyuan, don't be too nervous!"

Ye Zhining smiled awkwardly, and still persistently forced Cheng Ling to leave together, wanting to know the truth of the matter.

In the laughter of the crowd, they also walked out with him. In fact, most people are still skeptical, and they are always unsure without personal confirmation!

Seeing that everyone had such thoughts, Cheng Ling could only give up and return with them along the same road. Soon, everyone walked out of Xuanwu's belly and came to the ruins before, and at this time, several sergeants who were waiting outside greeted them.

Ye Zhining rushed to the front, grabbed one of the sergeants and asked, "Tell me, how long have we been in?"

The sergeant was stunned for a moment, although he saw that her appearance was beautiful, but she was violent, and something had happened, so he said: "Yudutong, you have only been in for a month, why did you come out so quickly, did you find any treasures inside?"

Ye Zhining breathed a long sigh of relief, and sensed herself again, as if it really had no effect as Jin Muchen said, and immediately put her mind at ease.

Cheng Ling smiled and said: "Okay, we didn't find any treasures inside, but we did see a secret realm that is very helpful for cultivation, this place is full of ruins, you don't have to wait outside, just go in with me later!"

The sergeant was overjoyed and was about to speak, but Jin Muchen asked, "How is the repair of the battleship progressing?"

"Tell the commander, everything is going well for the repair of the battleship, as long as you find the Dark Iron Essence, you can repair it all!"

Jin Muchen said, "Okay, hard work." In that case, you also call the monks who repaired the battleship here, and we will enter the secret realm together, and we may be able to find the whereabouts of the Xuantie Spirit as soon as possible. ”

When the sergeant heard this, he was glad to receive the order.

Three days later, when all the sergeants had arrived, Cheng Ling went into action again. This time, he planned to enter the portal opposite the hourglass to take a look, twice the time flow rate was still too slow for him, if there was a higher multiple behind him, his cultivation speed would definitely be faster.

Confident, he moved the small squares again in the changing arrangement of the nine palaces. But something strange happened, and the nine-square grid seemed to have a resistance, and it could not proceed according to the original arrangement no matter what.

"Could it be that the arrangement of these nine-square grids is unique? As long as you try once, you can't succeed the second time? Or do you need to wait for a while before you can take shape again? But how long does this time have to wait, I can't deduce it at all!"

Jin Muchen and Zhou Qingxi saw that Cheng Ling had been tinkering with it for a long time, and Xuanwu's abdomen had not opened the entrance like last time, and they couldn't help but wonder and asked, "Boy, what are you doing there, why don't you open the entrance soon!"

Cheng Ling's forehead was covered with beads of sweat, and he tried several times, but he still couldn't succeed, so he could only say helplessly: "Two seniors, this mechanism has changed, and the original arrangement can no longer open the entrance!"

"What? What can I do, is there any other way?"

"Wait, I'll figure it out!"

Everyone was helpless, they could only watch with their eyes blank, and there was nothing they could do.

Cheng Ling's mind turned sharply, the nine palaces are arranged in the previous order from one to nine, this no longer works, so next, what kind of way should be used? To be honest, there are many ways to arrange the nine palaces, and any one is possible.

But the Xingjun Mansion is by no means an ordinary place, what kind of power can build that kind of cultivation secret room that changes the passage of time? Others just see the benefits that this brings to themselves, but he can feel the heavenly ability of the person who built this sect!

Time, the movement of matter, the continuity of change, and the expression of the sequence, have always been eternal and unchanging. If there is anything in heaven and earth that is fair to any living being, it is time.

Changing the speed of time, what kind of existence against the sky is like opening a cheat, it only takes a few decades to reach hundreds or even thousands, tens of thousands of years of cultivation, this kind of achievement is extremely terrifying!

Therefore, he didn't dare to try it lightly, in case there was an extremely dangerous existence inside the open entrance, not to mention himself, all the more than 3,000 people on this trip would fall! Such a responsibility was too great to bear at all!

In general, he has been in this inexplicable world for about a hundred years, and he has experienced several desperate battles, but in Cheng Ling's heart, he still can't treat human life like a mustard, not to mention that these are his comrades-in-arms.

After a long silence, he turned around and said aloud to the thousands of monks behind him, "Ladies and gentlemen, the situation in front of us has changed a little, the hall we entered before can no longer be opened, or we need to wait for a while before we can open it again. ”

But how much time is needed in this, Cheng doesn't know. So, I decided to try another way to open the entrance, which I wasn't sure about and didn't know what it would look like. ”

Therefore, here, Cheng advises everyone that if you don't want to take risks, you can give up trying to enter. ”

As soon as his voice fell, thousands of sergeants immediately fell into their ears. There was a big buzz, and after a long time, a Dutong-level sergeant said: "Cheng Dutong, life and death are fateful, wealth is in the sky, everyone believes in you, as long as you open the entrance, whether to enter or not, but by heart!"

"Yes, Cheng Dutong, you can rest assured to open it! Although we are professional sergeants, we can take off this layer of armor and monks, and we are in danger of seeking wealth and wealth, and it is also my fate to wait for myself if I don't get the opportunity!"

"Please open the channel!"

"Please open the channel!"

“......”

Jin Muchen and Zhou Qingxi looked at each other, they really didn't expect Cheng Ling to have such prestige among these sergeants.

Ye Zhining even said: "Cheng Ling, you can rest assured to make a move! so many dangers have been broken through together, do you still care about such a time!"

Zhou Qingxi sighed: "This kid is really amazing!"

Cheng Ling smiled bitterly, and there was another burst of warmth. Many of these sergeants met in Pingshui, most of them didn't know each other, but they only led them into a few battles, and they trusted themselves so much. If you don't say anything, just keep trying according to your original idea!

At the moment, he didn't hesitate to move those blocks directly from the second change. Sure enough, after the second change started, the resistance in the square was no longer felt, and soon, the third change, the fourth change...... , and so on for a lap, and then to the first change of the second round.

"Click! Click!"

The sound of the machine sounded, and Xuanwu's abdomen once again appeared as a pitch-black passage!

Cheng Ling waved his hand and said, "Senior Uncle and Senior Zhou, let's go in first, and the rest of the sergeants will be outside for the time being, and we will follow one by one after I explore the way." ”

Everyone agreed, and at that moment, Jin Muxi, Zhou Qingxi, and Cheng Ling walked into the passage, and Ye Zhining groaned a little and followed.

The scene in the passage was the same as before, and after walking for half an hour, I saw a hall again, and there was still a huge hourglass in the center!

Ye Zhining was overjoyed and said, "Cheng Ling, you really found them again, I will notify them to come in immediately." ”

"Wait!" Cheng Ling hurriedly stopped and said, "Wait!"

With that, he walked towards the hourglass again. It didn't take him more than a moment to reach the edge, and this time, he noticed that the pattern at the bottom of the hourglass was a little denser. If the previous ring was symmetrical on both sides, the pattern seen here is divided into four halves.

After a few moments, his sense reached into the ring and found that the thread representing the hour hand was almost twice as fast. He knew it in his heart and said, "Time flows faster here than before, about four times faster than the outside!"

"What? You mean to practice here for four months, which is equivalent to one month in the outer world?"

"Yes, exactly!"

"That's great, I'm going to go out and let them in!"

Cheng Ling nodded slightly, she didn't find anything unusual in front of her, it should be fine. However, he didn't stand still and wait, but took out tens of millions of immortal crystals from the storage ring and began to set up the Spirit Gathering Formation!

The advantage of time can benefit everyone, but the immortal aura here is too thin, and he can't meet the supply of pills for every sergeant, so he can only do his best.

Soon, the Nine Palaces Spirit Gathering Array was arranged, and after those sergeants entered it, they all felt much more abundant than the previous immortal spirit qi. When they knew that this was the Spirit Gathering Array set up by Cheng Ling, they bowed to him gratefully one by one.

One of them also said: "Cheng Dutong, you took me into such a secret realm of cultivation, and also helped us set up a great array of spirit gatherings, how can I let you pay out of your own pocket again, everyone get together and return the immortal crystal to Cheng Dutong!"

Everyone agreed, and took out piles of immortal crystals from the rings, and soon filled more than half of the hall, looking at the posture, there were at least billions.

Cheng Ling smiled slightly, and said, "You don't have to be like this, so be it! These immortal crystals should be the spiritual source for you to set up the formation, you can cultivate here, I will try to enter that portal and see what is inside, according to speculation, it should be more helpful for cultivation!"

"But everyone must do what they can, the proportion of time here is four times that of the outside, relatively speaking, the mental pressure they bear is also greater, if they reluctantly enter the higher-level cultivation secret room, I am afraid they will not be able to bear it!"
