Cheng Ling's explanation made the sergeants in the field even more grateful. Some sergeants thought of their cultivation realm, and immediately sat down cross-legged and hurried to cultivate, while some of them had a higher cultivation level and did not move, but wanted to enter the portal with him to have a look.

He swept in all directions and saw that most of the cultivators of the Void Immortal Realm had entered the cultivation, and there were some Xuan Immortal Realms standing aside. I knew in my heart that these people wanted to go in and explore with themselves and others.

Don't speak at the moment, since everyone has made a choice, they are not afraid to waste saliva. After saying hello to Jin Muchen, he walked towards the door.

As soon as I entered, I found that it was also a hall, but it was much smaller than the previous one.

There was still a huge hourglass in the center of the hall, but Jin Muxi, Zhou Qingxi, and Cheng Ling felt that the mental pressure in the hall here was much greater than before.

Jin Muchen said: "The pressure here is even greater, but I feel that this pressure is of great help to the refining of spiritual power. ”

Cheng Ling nodded and said: "Yes, presumably these halls have the effect of refining spiritual power, but everyone has to do what they can, if they can't bear it in four months, it is likely to crush their spiritual power." ”

The rest of the people nodded one by one, and Chu Tianheng said: "Master, you see that there is another portal over there, and the walls in this hall are different from the previous one, and there are many patterns carved on it. ”

Everyone hurriedly followed the direction he pointed, and sure enough, they saw that there was a portal behind them, because of the angle problem, Cheng Ling and the others were blocked by the hourglass and just didn't see it.

Jin Muchen praised: "Yes, your observation is very detailed. ”

Chu Tianheng was happy in his heart, Jin Muxuan was thoughtful, he was dignified and heavy on weekdays, and rarely praised his disciples, not to mention that in front of so many people, Chu Tianheng's face was almost red with excitement.

Zhou Qingxi said: "Let's take a look at the mystery of the pattern on this." ”

Everyone agreed, and walked to the edge of the hall to check.

Cheng Ling came to the wall on the left side to take a closer look, and found that there were many characters depicted on it, those figures were in different shapes, each of them seemed to be demonstrating something, and he was about to probe out his spiritual power and study it carefully.

Over there, Zhou Qingxi's voice came over and said, "It seems that there is a technique depicted here, such a powerful cultivation method, and this exercise is even more than what I have learned." ”

The rest of the people were overjoyed, and hurriedly walked to him to see what kind of exercise it was, but even Zhou Qingxi of the Earth Immortal Realm sighed to himself.

But as soon as they saw it, they felt that their spiritual power was drastically consumed, and soon their brains became groggy, and some of the sergeants of the Void Immortal Realm fell down on the spot.

Cheng Ling was shocked, and hurriedly grabbed a sergeant who was about to faint, stretched out his hand and grabbed it, and the vitality probed into the opponent's body. After a look, his face changed greatly, and he hurriedly said loudly: "Everyone be careful, these exercise patterns are by no means simple, they can sharply consume your spiritual power, don't practice without authorization!"

Everyone's hearts sank, and they hurriedly withdrew their spiritual power. But some of the monks didn't seem to react, and they were puzzled for a while.

Cheng Ling carefully probed his spiritual power into those patterns, and sure enough, he saw that the patterns on the walls seemed to come to life, forming a long list of cultivation methods, which flashed in his mind one by one.

Observe for a moment, and immediately withdraw your mental power. Looking up, he saw that the cultivators who were still standing in the field had relatively high cultivation, and they were all staring at themselves tightly, although they felt the consumption of spiritual power, it was not strong.

Cheng Ling thought about it for a while, and then explained: "Everyone, your cultivation is different, and you don't need to use your spiritual strength, I said before that you must do what you can." Some of you can bear it, and you can naturally learn the exercises on the wall, but some of you can't, and you can estimate it yourself. ”

"However, the pressure in these secret rooms is of great help to the cultivation of spiritual power, and after practicing for a period of time, maybe everyone can bear it. ”

When he said this, everyone in the audience immediately relaxed, and if they felt good, they immediately began to try to cultivate the exercises on the wall, and if they couldn't bear it, they returned to the first hall and first improved their cultivation and spiritual power.

As a result, the number of monks in the second hall was suddenly reduced by more than half, and only about three hundred remained.

Cheng Ling waited for a moment, and then said, "Senior Uncle, Senior Zhou, why don't we enter that portal again?"

The two nodded, and Cheng Ling walked towards the portal! Jin Muxi, Zhou Qingxi, Chu Tianheng, Ye Zhining, Fangfang, and more than a dozen soldiers from the Xuan Immortal Realm all followed.

After entering, I found that the space inside was smaller, the mental pressure was greater, and there were still many patterns carved on the surrounding walls.

The faces of the dozen or so sergeants who followed behind them changed, and they felt that their endurance had reached the limit, sat down cross-legged, and began to resist.

Cheng Ling didn't check the pattern on the wall, but directly bypassed the hourglass, and sure enough, he found another entrance in the back.

He walked in without hesitation. Jin Muchen and others were afraid that he would lose, so they hurriedly followed.

In the fourth room, everyone felt a strong mental pressure coming, Chu Tianheng's face changed greatly, and he said, "Master, I feel that this is the limit of bearing!"

Ye Zhining also nodded with difficulty.

Jin Muchen said: "Okay, you cultivate here first, and don't enter the secret room behind!"

The two nodded, and sat down cross-legged.

In this way, there are only three people left: Cheng Ling, Jin Muxi, and Zhou Qingxi.

Zhou Qingxi said: "Boy, can you still bear it?"

Cheng Ling's face was indifferent, and he smiled: "It's okay!"

"What a pervert!" Zhou Qingxi scolded in his heart, knowing that the two of them were more than one realm higher than Cheng Ling, even they felt a lot more pressure, this kid didn't even change his face, it was really too wicked.

Cheng Ling didn't bother to explain, and walked straight to the fifth secret room. At this point, the three of them felt that the pressure had increased dramatically, and even they had to endure it very hard.

Jin Muchan glanced at Cheng Ling and said, "Cheng Ling, the pressure here is already extremely high, do you want to continue to move forward?"

Cheng Ling smiled bitterly: "Uncle Shi, you also think too highly of me, this is my limit!"

The two bigwigs secretly breathed a sigh of relief in their hearts, to be honest, it is already very unacceptable to fight with Cheng Ling, a junior in terms of spiritual power, if he can go further, where should the face of the two of them go, so many years of cultivation have been practiced to dogs.

Zhou Qingxi said, "Then let's cultivate in this hall!"

Cheng Ling was silent, he actually had a speculation in his heart. There are definitely more secret realms in the hinterland of Xuanwu, and there may be halls with a higher proportion of time.

But to find such a hall, it is necessary to go back, rearrange the combinations, and open a new entrance. For him, four times the time ratio was still too slow, and it was better to have about ten times, so that he could catch up with others in terms of cultivation speed.

He knew his situation too well, and the immortal aura required for cultivation was many times stronger than that of ordinary monks.

After thinking for a long time, he said: "Two seniors, it is estimated that the time multiplier here should be able to increase again, I want to try to go back to the entrance to find a new cultivation secret room!"

Zhou Qingxi was taken aback and said, "What should these people who were cultivating before, once we leave, they will be trapped in it!"

"No, according to my inference, the key to cultivating the secret realm here is in this ring, as long as the time in the hourglass is exhausted, and then flipped over again, I can continue to practice in it without leaving the hall. ”

In other words, they've been practicing for four times as long. If you can't bear it, you can leave, and once you leave, you can't re-enter the cultivation secret room with the same time multiple, or you need to wait longer. ”

"Now that I've set up a Great Spirit Gathering Array in my respective cultivation room, I'm sure they'll be happy!"

Zhou Qingxi said again: "Then why don't you take them to a higher multiples room together?"

Cheng Ling explained: "First, everyone's ability to bear is limited, and the time acceleration multiple increases, and the corresponding pressure is greater, so it is better to let them practice here." Of course, people like Senior Brother Chu, Senior Sister Ye, Fang, etc., can completely bear it, and they can go together. ”

"Second, in fact, I am not 100% sure that I will be able to find a higher multiples of the cultivation secret room, rather than taking the risk of trying, it is better to practice here, these are up to them. ”

Zhou Qingxi nodded silently, Cheng Ling was already very thoughtful, and there was no more micro-words.

The three of them retreated to the fourth room and told the fangs about it. After thinking about it for a moment, they all decided to explore the higher multiple cultivation room with Cheng Ling.

So, they went back to the third room, and after explaining the situation, six Xuan Immortal Realm monks also joined the team.

As for the two rooms in the back, Cheng Ling didn't say more, and only instructed them to leave the room and continue to practice, and then took the ten people behind him back to Xuanwu's abdomen.

He tried, and sure enough, the second combination didn't work again. Thinking about it, the second combination is fourfold, and so on, the third might be eight or sixteen. If it's sixteen times, you'll be practicing in it, and if it's only eight, you might have to try a fourth combination!

After thinking for a moment, he immediately started to act. Soon, the entrance opened, Cheng Ling walked in first, and as soon as he entered the hall, he saw that the pattern at the ring was a little denser, and he counted silently in his heart, and divided it into eight equal parts, obviously the time ratio here is eight times!

He then said, "Ladies and gentlemen, this is eight times the time ratio, how do you feel, if you can bear it, you can practice here! In the future, I estimate that it will be sixteen times, and it will be very difficult." ”

Fang, Chu Tianheng, Ye Zhining, and the monks of the Xuan Immortal Realm were silent for a moment, and they all said that eight times the time ratio was the limit, and they decided to cultivate here.

Cheng Ling nodded, looked at Jin Muchen and asked, "Uncle Shi, I want to try again, what do you think?"

Jin Muchen nodded in agreement, and Zhou Qingxi also said: "Boy, if you really have you, let's go back to the next floor!"
