The three of them returned to the bottom of the Xuanwu statue, and Cheng Ling entered the Nine Palaces again.

A moment later, another entrance opened.

The three of them walked in turn, Cheng Ling raised twelve points of vigilance, and said, "Two seniors, the time ratio here should be sixteen times, and the mental pressure must be extremely great, so you must be prepared accordingly." ”

Jin Muchen and Zhou Qingxi nodded silently, and they slowly came to the hall. After entering the hall, I felt that although the pressure was a little greater than before, it was not to the extent that it was unbearable.

Cheng Ling muttered to herself, could it be that her guess was wrong. He didn't give up, walked to the hourglass and looked closely, and after a while, his face became even more depressed. I saw that the circle below the hourglass was symmetrical to the left and right of exactly ten sets of patterns, and it was speculated that the speed of time in this place was ten times that of the outside.

Cheng Ling wondered, "What's the matter, the increase in time in this secret room is unreasonable!"

Jin Muchen smiled and said, "Manpower is sometimes exhausted, do you think that time acceleration can be extended indefinitely? What kind of realm should the power of building these secret rooms reach? Boy, be content, ten times the time is much higher than usual." ”

Cheng Ling was silent, he didn't know, just as Jin Muchen analyzed, in order to build this kind of secret realm with different time proportions, he must first comprehend the most difficult time mystery between heaven and earth, and the realm should not be too low.

The monks who built these secret realms back then did not reach the top level of comprehension of the mysteries of time, and reaching a tenfold ratio was already the limit!

Cheng Ling took a deep breath and felt that what Jin Muchen said was also reasonable, so he stopped dwelling on it. It was about two years since he left Ling Weixing, and there were still eight years left before he made the original ambition of ten years to find a way to heal Yang Hongqiu, and then counting the time needed to go back and forth, there were still seven years.

In other words, with a tenfold time ratio, I have at least seventy years to practice! After a little hesitation, he said, "Thank you for your teachings, I have decided to practice here!"

Jin Muchen and Zhou Qingxi nodded silently, giving and giving, Cheng Ling's heart was much more stable than before.

Cheng Ling took out a bunch of immortal crystals from the storage ring and prepared to set up a spirit gathering array, Jin Muxi and Zhou Qingxi saw it, and also threw a bunch of them out of the ring, and said, "Boy, adding these should be enough!"

Cheng Ling smiled and nodded, although his net worth was not bad, the two bigwigs were willing to contribute immortal crystals. If you want to quickly improve your cultivation, the energy consumed will be many times that of ordinary people.

He didn't shirk it, put those immortal crystals according to certain rules, and in less than a moment, one after another array flags fell, and the Nine Palaces Spirit Gathering Great Array rose. At this moment, the immortal aura in the secret room was almost the same as the thirty times the richness of cultivation in the base camp.

The two bigwigs nodded in satisfaction, and then looked for a corner and began to cultivate.

Cheng Ling didn't stop, and set up a hidden formation beside him. There are too many secrets on his body, and although the two seniors have blue eyes, they don't want to reveal them publicly.

Take out all the alchemy materials from the ring first, seventy years is enough time to do many things by yourself. Dan Fu Array Three Dao, the Formation Dao is too time-consuming, you can slow down your cultivation, Dan Dao and Fu Dao are of great help to combat power, and future cultivation also needs the help of Dan Medicine, take this opportunity, at least to be promoted to the Spirit Pill Grandmaster.

Now that he has reached the peak of an intermediate elixir master, he can be promoted with a little more strength

From level to high-level, the elixir of the Xuan Immortal Realm is even more refined, and it is even more handy. After arriving at the Grandmaster, he could refine the cultivation elixir of the Earth Immortal Realm, which would be of great help to Jin Muxi, Zhou Qingxi, Fangfang, and others.

There is also the talisman, after many battlefield battles, I deeply feel the help that the talisman brings to me. This is a means of increasing combat power, whether it is a solo duel or a group battle, it is very useful.

After the nine-grade rune, what was refined was the spirit rune, and the grade was raised, which posed a greater threat to the monks of the Yin Yang Realm and the Void Immortal Realm.

And so, thirty months in the chamber and three months later. All the materials in the storage ring were refined, and the Dan Dao grade successfully advanced to the Spirit Pill Grandmaster, and the Soul Rejuvenation Pill that healed Yang Hongqiu was also refined.

The elixir assisted in the cultivation of the Earth Immortal Realm was called "Earth Spirit Pill", and Cheng Ling refined more than 200 pieces respectively, and Jin Muchen and Zhou Qingxi each had 100 pieces. It's a pity that Fangs are not by his side, otherwise I believe that his cultivation will improve faster.

The two bigwigs were woken up by Cheng Ling, looking at the elixir in front of them in shock, Jin Muchen took a deep breath, and asked suspiciously, "Boy, is this really refined by you?"

Cheng Ling spread his hands and said, "Is there a fourth person here?" Uncle Shi, if you don't like the juniors, you can take it back." ”

Jin Muchen hurriedly snatched it, snorted coldly and said, "That's it, just think of it as your filial piety to your elders!"

Zhou Qingxi sighed, people are from the same family, and they can be cheeky to say that it is Cheng Ling's filial piety, but he can't say such a thing. But the temptation of the Earth Spirit Pill was too great, so he sighed a little, and then said, "Cheng Ling, thank you, that's it, I still have a lot of pill materials here, I wanted to bring them back to the sect, since you know alchemy, these materials will be given to you!"

Cheng Ling was overjoyed, and hurriedly stretched out his hand to take it, and said, "Senior, if you have the materials for the talisman, you can also give it to me, and I will be responsible for helping you refine it!"

Zhou Qingxi smiled bitterly, simply threw the storage ring over, and said, "Take whatever you want!"

Cheng Ling smiled, and unceremoniously scavenged all the materials he could use in his storage ring. When he was finished, he turned his head and looked at Jin Muchen with resentment, his expression was as if he owed him tens of billions of immortal crystals.

Jin Muxuan's old face turned red, and he was completely defeated by him, so he had no choice but to throw the storage ring over.

Cheng Ling was happy, drew a gourd in the same way, scavenged all the materials on the two bigwigs, and continued to drill into the hidden formation to refine it.

After another thirty months like this, his Dan Dao grade was even more solid, reaching the peak of the Spirit Pill Grandmaster. At this time, he was sure to refine the Nine Turns Soul Restoration Pill, and when he left the Star Domain Battlefield, he would go to find the materials he needed.

After refining the elixir materials, the next step is to study the talisman. It took five years in the secret room, all the materials were consumed, and the rune realm was also raised to the grandmaster level, and the talisman that was refined could already threaten the cultivators of the Earth Immortal Realm.

With a sigh of relief, ten years have passed unconsciously, which is equivalent to a year in the outside world, and the cultivation of Jin Muchen and Zhou Qingxi has taken a small step forward, and it is time for him to start cultivating.

However, within this year, he was completely familiar with the mental pressure in the secret room, and he could no longer satisfy the spiritual refinement. After thinking about it for a long time, I decided to enter the secret room inside to cultivate, presumably under greater pressure, my spiritual power could also improve quickly.

He was not alarmed

The two bigwigs, instead, retained the hidden formation originally set up and stepped into it in one step.

After entering, I felt a completely different mental pressure, and the effect of refining spiritual power in the second secret room was twice as strong as before. He immediately took action, and set up a great array of spirit gathering again, this time directly throwing out more than a billion lower-grade immortal crystals, and the immortal spirit qi in the secret room was rich, reaching forty times that of the outer world!

He took out the prepared Xuanling Pill from the ring, sat down cross-legged, closed his eyes, and began to refine it.

Cultivation has no time, and thirty years have passed quickly, which is equivalent to three years in the outside world. Cheng Ling's cultivation finally reached the Nine-Star Xuan Immortal Realm, and in the past thirty years, the Eight Extremes Dao spells have become more proficient, and the spells of all systems have reached their peak.

Finally, after all the spells had been cultivated, in his sleep, the golden pages once again taught him a method to enhance the spells. Strictly speaking, this method is not a spell, but a technique on how to speed up the release of a spell.

This technique will open up nine passages connecting the dantian space, and each passage will be opened, the immortal aura in the dantian will be like a highway, which can be directly triggered, and the speed of spell release will be much faster!

After Cheng Ling woke up, he was shocked by the powerful effect of this technique. You must know that no matter what kind of spell it is, it needs to be released between two spells for a period of time, and it cannot be released endlessly.

And this technique can greatly shorten the interval between spell releases, and once all the nine meridians are connected, the spell release speed can be doubled.

This kind of gap is very scary, for example, if you release one spell in a certain period of time, others may release three, and the gap between the two may not feel big.

But if you fight for a long time, you have unleashed ten kinds of spells, and people have already struck thirty times. It's like one person against thirty people, such a dense firepower strike, the innate inferiority, not to mention that the power between magic and magic has not been weakened by half a point.

But to open up these nine meridians, it is by no means a simple matter.

Each line of heaven and earth needs nine powerful souls as traction, refining it into the meridians, from the upper dantian mud pill palace, to the middle dantian Jizhong acupoint, and then to the lower dantian Guan Yuan acupoint, the three dantian are connected into a straight line, implying the heaven and earth line connecting the human body.

The upper, middle, and lower three dantians need the strongest souls, plus six slightly weaker souls to form a line, which can be regarded as opening up a "heaven and earth line" that runs through the body!"

In this way, the remaining eight heaven and earth lines also need nine souls, all of which are nine hundred and eighty-one souls. There is no limit to the soul level, but the souls of the upper, middle, and lower dantians, as the main transmission sites of the immortal spirit power in the body, must be one level higher than the other six souls.

For example, if the remaining six acupuncture points are cultivated by the soul of a monk in the Void Immortal Realm, then the upper, middle, and lower dantian sacrifices must be the soul of a monk in the Xuan Immortal Realm. Of course, as the monk's own realm improves, the more powerful souls obtained can also be replaced.

And the stronger the soul, the greater the speed bonus of the heaven and earth line auxiliary spell casting, the initial nine meridians are all opened, according to speculation, at least twice the speed of the shot, this is a very terrifying gap, which is equivalent to the power of the spell has also been increased by two times!

What's more, it can also enhance the cultivation of the sacrificial soul and increase the speed of spell release again, in other words, this speed bonus has infinite room for improvement!
