Accelerating cultivation is actually to accelerate the condensation of chaotic Nirvana true fire, that is, to gather the energy released by Jiuyang in September faster, so as to extract more chaotic Nirvana true fire within a certain time and gradually achieve the cultivation effect of quantitative change causing qualitative change.

The Yang crystal contains the energy cast and released by the Nine Yang in the sky, but the energy in it can not extract the masculine Nirvana true fire. The energy emitted by the Nine Yang falls into the eternal world. Part of it comes together to form the Yang crystal, part is absorbed by the nature of heaven and earth, and part provides light and heat. Monks condense the nirvana true fire, Is to absorb this part of light and heat.

Like Yang crystal, Moon Crystal cannot extract Nirvana true fire.

Monks are often step-by-step in the practice of Nirvana true fire, and it is difficult to take a shortcut.

Considering this, Xiao Lingyu suddenly thought of the mysterious array that can make yuejing, and said in his heart: "that array should be used by a month attribute friar to accelerate the cultivation of Nirvana true fire, not to make yuejing!"

In the next period of flight, he began to devote himself to the research and understanding of the array. At the beginning, he just recorded it in the depths of his soul. He has never had time to sink in and understand it. At present, he is just free. He can see if he can make a breakthrough in this regard.

After all, Xiao Lingyu was a powerful array Taoist before he ascended, and he had a strong ability to study array prohibition. Linger also got a lot of jade slips and ancient books about array prohibition in those treasure houses. As long as he studied them carefully, he would first study those jade slips and ancient books to enhance his understanding of array prohibition in the immortal world, and then understand the array map.

The round bowl magic weapon has been flying for nearly a hundred years, and elder sister Gu also caught up. During this period, in order to rest and not easy to be tracked, he still stayed or circled, otherwise elder sister Gu would have to spend more time with everyone.

"Elder sister Gu, do you have a more detailed method of forbidden array?"

After some greetings, Xiao Lingyu asked elder sister Gu with expectation.

"Yes, I'm a little expert in the way of prohibition." elder sister Gu smiled.

In the next 100 years of flying, elder sister Gu taught Xiao Lingyu all the methods she had mastered to stop the formation. When she found that Xiao Lingyu also had great attainments in the way of stopping the formation, she discussed with Xiao Lingyu day and night, and learned a lot from Xiao Lingyu.

Xiao Lingyu had a very good foundation for prohibition. Coupled with elder sister Gu's patient Professor, he naturally gradually mastered the characteristics of the way of prohibition in the eternal world.

After flying for another 200 years and more than 400 years after leaving Huludao, Xiao Lingyu finally understood the mysterious array. He couldn't wait to try it.

"At present, we have flown over hundreds of millions of mountains and rivers and are very far away from huluwan. Even if we don't give up, I'm afraid it will be very difficult to find us for a while. It's better to stop first and settle down." Xiao Lingyu suggested.

"So good."

Elder sister Gu had no opinion, but said again: "my husband and I built a temporary cave nearby. The cave was protected by the forbidden array arranged by my husband. I think it's still there now. Let's go there and settle down first."

Naturally, the Xiao Lingyu family had no opinion. At present, elder sister Gu controlled the round bowl to fly.

After only flying for a month, elder sister Gu put away the round bowl and landed in a grand canyon with everyone.

The Grand Canyon is formed by the impact of a fast flowing river. On both sides are 10000 high mountains, which are all wrapped by lush trees.

The water in the canyon flows ceaselessly, the river is steaming with rolling water mist, and there are bursts of roaring sounds of fierce animals from time to time in the mountains and forests on both sides.

The Grand Canyon is thousands of miles long. The cave referred to by elder sister Gu is at the waist of a steep cliff in the middle of the Grand Canyon. The entrance is only three feet high. From the outside, there is nothing special. You can even see birds fluttering out of it.

Even if it landed at the entrance, Xiao Lingyu didn't feel the fluctuation of the forbidden array. It can be seen that elder sister Gu's husband is also an expert in the way of forbidden array.

Under the leadership of elder sister Gu, everyone entered the cave in turn.

The cave is very long, and it has always been one person wide, and it is still dark everywhere.

"Father, I don't like it here," said Xiao Ni with a red 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 a spacious and bright courtyard.

"Ha ha, it's just temporary settlement." Xiao Lingyu smiled.

At present, several mothers restrict their children to talk less.

After walking nearly ten thousand feet, the cave came to an end, and a rugged stone wall blocked the way forward.

Elder sister Gu waved her hand and played a seal formula. The stone wall disappeared after a strange wave, but another stone door was exposed.

The stone gate is simple and solid.

Elder sister Gu pinched the printing formula again, but she played nearly 100 groups of printing formula, and the stone gate opened slowly.

Behind the stone gate is a large cave.

The cave is no less than 300 feet in length and width, and there is a pool about 150 feet in length and width in the center, in which there is a small pavilion.

In the pool, there are aquatic plants, large pieces of duckweed floating on the water, and there are happy swimming fish in the water.

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

Those flowers and plants are extraordinary. Even if they have not been taken care of for many years, they also appear flexible and prosperous.

There are many stone gates on the stone walls around the cave. Behind those stone gates, there should be a quiet room or secret room for cultivation.

"There are a few rooms here, but it's easier to dig a few more quiet rooms. You go around first and I'll open a few more quiet rooms."

With that, elder sister Gu flew under a stone wall. First, she pinched the moving seal formula to untie the prohibition on the stone wall, and then chiseled the stone wall. In the time of a cup of tea, a new quiet room appeared.

After digging more than ten quiet rooms, elder sister Gu blessed and adjusted the forbidden array in the cave, and taught Xiao Lingyu the manipulation of the forbidden array in the cave.

After staying in the cave for a month with everyone, when everyone was familiar with the cave, elder sister Gu said, "if sister linger has nothing to do, would you like to go out with her?"

The so-called going out is naturally going out to find the place where the treasure is hidden.

Ling'er has a special physique. She can't practice like everyone else, so she's also an idle person in the cave. She also wants to go out more. Maybe she can run into an opportunity to improve her strength, but she still looks at Xiao Lingyu.

"It doesn't hurt to go out and walk around, but be careful. Don't do anything. Don't force it." Xiao Lingyu nodded.

With Xiao Lingyu's permission, ling'er followed elder sister Gu to leave the cave temporarily.

After ling'er and elder 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 by elder sister Gu, and began to depict the mysterious array.

It has been studied and understood thoroughly, so it is not difficult to depict the array. In less than a day, the array has appeared on a high-quality stone slab.

Pinch the magic formula into the array, and the lines on the array began to flow slowly.

When the time came to night, a clear glow of moonlight was strangely gathered by the array through the thick and huge body.

Under the influence of this array, with the cave as the center, the moonlight and clear brightness in a radius of hundreds of miles rush here, and the speed of gathering is more than 100 times faster than that of Xiao Lingyu.

Xiao Lingyu knelt in the center of the array and began to release the true fire of chaotic Nirvana and the chaotic force for refining

With the improvement of strength and realm, Xiao Lingyu's speed of refining Nirvana true fire has accelerated a lot. With the help of the array, it took him hundreds of thousands of years to refine a ray of monthly Nirvana true fire last time, but this time it took less than a thousand years.
