Accelerating the cultivation means accelerating the condensed chaotic Nirvana true fire, which means that you can gather the energy emitted by the Nine Yang month faster. Only in this way can you extract more chaotic Nirvana true fire within a certain period of time, and gradually achieve the cultivation effect of quantitative change causing qualitative change.

The yang crystal contains the energy emitted by the Nine Yang in the sky, but the energy inside cannot extract the masculine Nirvana True Fire. The energy emitted by the Nine Yang falls into the immortal realm, and part of it gathers together to form the yang crystal, part of which is absorbed by the nature of the heaven and earth, and part of it provides light and heat. The monks condense the Nirvana True Fire to absorb this part of the light and heat.

Like the yang crystal, the moon crystal cannot extract the true fire of Nirvana.

When cultivators practice Nirvana True Fire, they often follow the steps and find it difficult to take shortcuts.

Thinking of this, Xiao Lingyu suddenly remembered the mysterious formation map that could create moon crystals, and said in his heart: "That formation map should be used by a certain moon-attributed cultivator to accelerate the cultivation of Nirvana True Fire, not to create moon crystals!"

During the next period of flight, he began to devote himself to the study and understanding of the formation map. At that time, he only recorded it in the depths of his soul and had no time to understand it in peace. He is now free, so he can see if he can make a breakthrough in this regard.

After all, Xiao Lingyu was a powerful formation master before ascending, and had extremely strong ability to study formation prohibitions. Ling'er also obtained many ancient jade slips and ancient books about the way of forbidden formations in those treasures. As long as he practiced it carefully, he first studied the ancient jade slips and used it to enhance his understanding of the way of formation prohibitions in the longevity world, and then understood the formation diagram.

The round bowl magic weapon has been flying for nearly a hundred years, and Sister Gu also chased me. During this period, he stayed or circled in order to rest and not be easily tracked, otherwise Sister Gu would have to meet with everyone for a longer time.

"Sister Gu, do you have a more detailed method of the forbidden array method?"

After some greetings, Xiao Lingyu asked Sister Gu with anticipation.

"Yes, I'm also considered a master of the ban." Sister Gu said with a smile.

In the next hundred years of flight, Sister Gu taught Xiao Lingyu all the methods of the forbidden formation she mastered. When she found that Xiao Lingyu was also very accomplished in the forbidden formation, she discussed it day and night with Xiao Lingyu, and learned a lot from Xiao Lingyu.

Xiao Lingyu already has an extremely good foundation for bans, and with Sister Gu's patient professor, he naturally gradually mastered the characteristics of the forbidden formation in the immortal world.

After flying for another two hundred years, after leaving Huludao for more than four hundred years, Xiao Lingyu finally understood the mysterious formation map. He couldn't wait to try it out.

"Now it has flown over billions of mountains and rivers, and it is very far away from Hulu Bay. Even if I don't give up, I'm afraid it will be difficult to find us in a while. It's better to stop and settle down first." Xiao Lingyu suggested.

“That’s good.”

Sister Gu had no objection, but said again: "My husband and I built a temporary cave nearby. The cave has the forbidden array protection arranged by my husband. I think we are still here, so let's go there first."

Xiao Lingyu and his family naturally had no objection, so they controlled the round bowl and turned to flying.

After only one month of flying, Sister Gu put away the round bowl and took everyone to land in a grand canyon.

This Grand Canyon is formed by a turbulent river. The two sides are thousands of high mountains, and the mountains are all surrounded by lush forests.

The water in the canyon flows continuously, the river is filled with rolling mist, and the sounds of beasts roaring from the mountains and forests on both sides are heard from time to time.

This Grand Canyon is thousands of miles long. The cave that Sister Gu pointed out is located on the waist of a steep cliff in the middle of the Grand Canyon. The entrance is only three feet wide. There is no special point from the outside. You can even see birds flapping their wings and flying out of them.

Even when it fell to the entrance, Xiao Lingyu did not feel any fluctuations in the forbidden formation. It can be seen that Sister Gu’s husband is also a master of the forbidden formation.

Under the leadership of Sister Gu, everyone entered the cave one by one.

The cave is very long and always one person wide, and it is still pitch black all over the place.

"Father, I don't like this place." Xiao Ni said with her red and beautiful mouth in her mouth.

"I don't like it either!"

Xiao Hong and the other five children also looked unhappy, after all, they were used to living in spacious and bright courtyards.

"Haha, it's just a temporary stop." Xiao Lingyu said with a smile.

At present, several mothers are restraining their children and letting them talk less.

After walking nearly ten thousand feet away, the cave was at its end, and an uneven stone wall blocked the way forward.

Sister Gu waved her hand and made a seal, and the stone wall disappeared after a strange wave, but another stone door was revealed.

The stone door has a simple shape and looks extremely solid.

Sister Gu pinched the seal again, but after nearly a hundred sets of seals were printed, the stone door slowly opened.

Behind the stone gate is a large cave.

The cave is not less than three hundred feet long and there is also a pool in the center with a length of about one hundred and fifty feet wide. There is a small pavilion in the pool.

In the pool, there are aquatic plants, and large patches of duckweed floating on the water surface, and there are fish swimming happily in the water.

Around the pool, there are many stone piers and stone tables, and there are also strange flowers and plants competing for beauty.

Those flowers and plants are extraordinary, and even if they have not been eaten for many years, they still look lively and prosperous.

There are many stone doors on the stone walls around the cave. Behind those stone doors should be a quiet room or a secret room for practice.

"There are a few rooms here, but it is easier to dig a few quiet rooms. You guys will take a walk first, and I'll open a few more quiet rooms."

After saying that, Sister Gu flew under a stone wall. She first pinched the seal and untie the ban on the stone wall, and then chiseled the stone wall. In just a cup of tea, a new quiet room appeared.

After digging more than ten quiet rooms, Sister Gu blessed and adjusted the ban and formations of the cave, and taught Xiao Lingyu the control technique of the ban and formations in the cave.

After staying in this cave for a month, when everyone was familiar with this cave, Sister Gu said, "If Sister Ling'er is fine, would you like to accompany her to go out for a walk?"

The so-called going out for a walk is naturally going out to find a place to hide treasures.

Ling'er has a special physique and cannot practice like everyone else, so she is also an idle person in the cave. She also wants to go out for more things, maybe she can get into some opportunities to improve her strength, but she still looked at Xiao Lingyu.

"It's okay to go out and have a walk around, but be careful in everything. Don't do anything, don't force it." Xiao Lingyu nodded and said.

With Xiao Lingyu's permission, Ling'er followed Sister Gu and temporarily left the cave.

After Ling'er and Sister Gu left, Xiao Lingyu first helped his wife, friends and children enter the state of cultivation, and then he entered the largest quiet room dug out by Sister Gu, and began to carve the mysterious array diagram.

I have already learned and understood it thoroughly, so it is not difficult to carve the array diagram. In less than a day, the array diagram appeared on a very high-quality stone slab.

Pinch the magic tricks into the array diagram, and the patterns on the array diagram begin to flow slowly.

When the time came, streams of moonlight shining strangely passed through its thick and huge body and were gathered by the formation.

Under the action of this formation, the moonlight with the cave as the center, with hundreds of miles of radius flowing towards this side, and the speed of gathering was more than a hundred times faster than that of Xiao Lingyu with his divine thoughts.

Xiao Lingyu stood cross-legged in the center of the formation map and began to release the Chaos Nirvana True Fire and Chaos Force to refine...
