Seeing that Chang Shan came back in just over a month, Yu Wanting was very surprised and curious, but Chang Shan fulfilled his promise in this way, she was happy, and she didn't want to know what Shangguan Qing asked Chang Shan to do in the Qinglian Sect, so she didn't ask Chang Shan anything.

Whether Shangguan Mei can survive the Ninety-Nine Heavenly Tribulation is related to whether the Qinglian Sect will be stronger, this matter is too important to the Qinglian Sect, Chang Shan hesitated for a moment, and did not explain it to Yu Huanting.

After playing with Chang Chongyu for a few days, when Chang Shan accompanied Yu Huanting and Chang Chongyu again, most of his attention was placed on the eight earthy yellow dragon scales in the dantian to understand their nature.

When it comes to the spiritual objects that are suitable for the formation between heaven and earth, the first thing that all cultivators will think of is the spirit silk, followed by the spirit jade.

Spirit silk and spirit jade are suitable for array, because they are very suitable as a medium for the circulation of spiritual power, and their own spiritual power is very inclusive and very pure.

However, spirit silk and spirit jade also have their drawbacks.

First of all, no matter how good the spirit silk is, no matter how good the spirit jade is, the spiritual power it can carry is limited, so the formation arranged with the spirit silk and spirit jade has certain limitations in terms of scope and durability.

For a powerful sect, the sect's sect protection formation must not be arranged with a formation flag made of spirit silk, let alone a formation base condensed by spirit jade.

Secondly, the spiritual power of spirit silk and spirit jade has a great inclusiveness, but at the same time it lacks certain characteristics.

Compared with the tortoise shell of the turtle with the turtle back silkworm above the sixth grade, it is much more difficult to refine the formation with the tortoise shell as the material than the turtle back silkworm as the material to refine the formation, but when it comes to the power of the formation, the formation made with the turtle back silkworm as the material cannot be compared with the formation refined with the tortoise shell as the material.

Refining Masters and Dan Dao Grandmasters, they can achieve higher achievements on the Instrument Dao and Dan Dao, which is manifested in the fact that they can refine more powerful magic weapons and pills, and can design more powerful magic weapons and pills;

Compared with the formation cultivation that refines the Yuan Fu Banner, the formation cultivation that has the ability to refine the spiritual object into a formation to give full play to the characteristics of the spiritual object is generally respected as the Great Grandmaster.

When the great grandmaster reaches a certain realm, he can lay out a formation that forms a world by himself according to the characteristics of the spiritual power of a region, and between the rotation of his mind, such a formation master is the legendary divine formation master.

Although Chang Shan had already reached the realm of a grandmaster in the Golden Formation Formation, the Wood Formation Formation, the Water Formation Formation, the Fire Formation and the Five Elements Formation, even on top of his highest talent and attainments in the Earth Formation he was not qualified to be called a Great Grandmaster.

However, Chang Shan had referred to his understanding of the Zhou Tian Xuanwu Star Array, and refined a set of Xuanwu Array with the four Xuanwu tortoise shells he had obtained over the years.

This set of Xuanwu Array is Chang Shan's most satisfactory set of formations, although the defensive power cannot be compared with Zhou Tian's Xuanwu Star Array, it can barely be regarded as a low-grade divine array. Chang Shan didn't need the Xuanwu Array to protect himself, so when he evolved the Xuanwu Array to a relatively perfect level, he gave it to Chang Runyu.

Since the ordinary formations refined with spirit silkworms were basically not helpful to Shangguan Meidu Heavenly Tribulation, the formations she asked Chang Shan to refine were all formations made of rare spiritual objects.

At this time, the eight earthy yellow dragon scales in Changshan's dantian were the earthy spiritual objects among the spiritual objects that Shangguan Mei gave to Changshan.

When Chang Shan first began to comprehend the nature of the eight earthy yellow dragon scales, he could still divide part of his mind to chat with Yu Huanting, looking at Chang Chongyu, when he was somewhat familiar with the nature of the eight earthy yellow dragon scales, he often put all his mind on the nature of the eight dragon scales, and sometimes sat for several days.

Although Yu Wanting loves to be coquettish, she didn't bother Chang Shan at this time, nor did she let Chang Chongyu disturb Chang Shan.

Three and a half years have passed in a blink of an eye, and Chang Shan has basically comprehended the spiritual wisdom of the eight earthy yellow dragon scales, and he has also roughly deduced a formation in his heart that can give full play to the nature of these eight dragon scales.

Deducing the formation requires full attention, so Chang Shan began the retreat with a little apology.

With the Ten Thousand Souls Disk to perfect the formation deduced from the bottom of his heart, Chang Shan imprinted the formation base in the eight dragon scales, and then, laid out the formation, while deducing the formation, while modifying, until the formation can basically bring out the characteristics of the dragon scales, he stopped.

After collecting the refined formation, Chang Shan went out.

After accompanying his wife for more than ten days, Chang Shan took out seven minerals that seemed to contain the power of endless earth and fire, probably dripping blood to recognize the master, and entered the dantian, and understood their nature.

In less than two months, Chang Shan became familiar with the properties of the seven fire minerals, and as before, he was often completely immersed in the perception of the properties of the seven minerals.

At this time, although Chang Chongyu was still young, he also knew that Chang Shan was contemplating the mysteries of heaven and earth when he lost his mind, and he no longer clamored for Chang Shan to play with him.

From time to time, Chang Shan woke up from his perception of the nature of the seven minerals in his body, and he felt a little guilty when he saw Chang Chongyu playing quietly on the side.

He thought about waiting for Chang Chongyu to grow up and then help Shangguan Mei refine the formation, but this was the first time that Shangguan Qing asked him to help since he lost Shangguan Qing, and he wanted to do his best to make this thing perfect, so he hesitated, he only accompanied Chang Chongyu for a while when he was sober, and then continued to comprehend the nature of the seven minerals in his body.

In the blink of an eye, more than four years had passed, and Chang Shan had comprehended the properties of the seven minerals, and had probably deduced the formation that could bring out the properties of the seven minerals, so he began to retreat and refine the formation.

In the blink of an eye, another seventeen years have passed.

When there were still two years left before the thirty years that Chang Shan had said, Chang Shan refined all the spiritual objects that Shangguan Mei gave him into a formation.

After staring at the five five-colored cobblestones in his hand for a while, Chang Shan let out a long breath, put the five cobblestones into the storage ring, and escaped out of the secret room.

When Chang Shan arrived at the dormitory, he was slightly stunned when he saw that Yu Wanting was not there, and he sensed the breath in the palace of Yushan, and found that Yu Wanting was in Chang Runyu's room, and Chang Runyu was cultivating through a secret method similar to "Tianyan Jue", but Chang Chongyu was in the palace.

With a slight frown, Chang Shan woke up Huo'er, who was also in retreat.

"Huo'er, where is the young master!"

"Cultivate the formation with General An at General Zuo in Shanshui City!"

"Cultivating formations?"

Chang Shan was stunned for a moment, and walked out.

When he arrived at Shanshui City, Chang Shan asked left and south, and saw that Chang Chongyu was really serious about practicing the formation with An Yuchen again, he explained a few words to An Yuchen, and then returned to the Yushan Palace.

As soon as Chang Shan entered the Yushan Palace, Yu Huanting and Chang Runyu greeted them, but it was Huo'er who informed them of the news of Chang Shan's exit.

The three of them came to the Jade Garden together, sat down in the Jade Mountain Pavilion on the side, and laughed for a while, Chang Shan looked at Yu Huanting and said, "Why did Chongyu think about learning the formation?"

"It's not under your influence yet!"

"Really influenced by me?"

Chang Shan asked rhetorically, nodded, and said in a deep voice: "Runyu's temperament is not calm enough to cultivate the formation path with me, I hope Chongyu will like to deduce the formation." ”

Yu Wanting nodded first, and then looked at Chang Shan with a complaining face: "Chongyu is not only influenced by you and likes the formation, but also a little taciturn by you, and only knows how to cultivate. ”

"Really?"

Chang Shan was stunned for a moment, and his brows furrowed.

He hoped that Chang Chongyu could study the formation with him, but he didn't want Chang Chongyu to be a person who was not good at talking. Although the cultivation world respects strength, those who are not good at talking also suffer a little.

"But don't worry too much, Chongyu is just a little bit young, although he is a little taciturn, but he is very smart. ”

Seeing Chang Shan frowning, Yu Wanting comforted.

Chang Shan nodded and asked about Chang Runyu's cultivation.

The three of them chatted about cultivation for a while, chatted about the past for a while, and before they knew it, more than two hours had passed, and the sky had darkened.

When Chang Shan and Yu Huanting returned to the dormitory, they couldn't help but ask about Chang Chongyu's situation.

"Don't worry, husband, Chongyu is very smart, he doesn't like to talk, he just thinks that silence is more imposing, and it's not that he is not good at talking. ”

"Silent and imposing?"

Chang Shan was stunned for a moment, sighed, and said softly: "I knew that I would have this kind of impact on him, so it is better to stay in retreat all these years." ”

Yu Wanting shook her head and replied softly: "If you keep retreating, not to mention that it is a defect for him, the other character he has developed may not be good. ”

After a slight pause, Yu Huanting sighed again: "It's a pity that he is very assertive at a young age, which makes me a little unaccustomed to being a mother." ”

"As long as it's not self-serving, it's good to be assertive. ”

Chang Shan replied with a smile, grabbed Yu Huanting's hand, and said with a smile: "Since Chongyu has grown up now, it is better for us to have another child." ”

Yu Wanting was stunned for a moment, a red glow appeared on her face, and she glanced at Chang Shan coquettishly.

When the clouds and rain stopped, Chang Shan hugged Yu Wanting and said softly: "In a few days, I will go to Yingzhou, and it may take two years to come back." ”

A touch of unnaturalness appeared on Yu Huanting's face, and she nodded slightly.

She is not the kind of person who is not smart, of course she can guess that Chang Shan's return to Yingzhou is related to Shangguan Qingqing's invitation to Chang Shan to Qinglian Sect.

She had trouble with Chang Shan back then, and now she won't.

After Chang Shan finished talking about going to Yingzhou, he didn't know what to say next, but hugged Yu Huanting tighter.

After a while, Yu Huanting broke the silence and said, "Three days later, Yu'er and Runyu will retreat again, and when we are in retreat, you are leaving." ”

"Hmm!"

Chang Shan nodded and said softly: "When my husband comes back from Yingzhou, I will take you to the Sand Sea to have a look." ”

Yu Wanting responded first, then shook her head and said softly: "When you refine the Five Elements Heavenly Wheel, let's go to the Sand Sea again!"

When Chang Shan heard this, he was a little moved in his heart, and the tenderness in his eyes seemed to be pouring out, he kissed Yu Wanting heavily on the forehead and nodded.

Yu Wanting returned a sweet smile, shrunk her body into Chang Shan's arms, and closed her eyes.
