Chang Shan felt that it was unlikely that Jian Zun would send someone to Qizhou to deal with him, but just in case, he returned to Tianshan and arranged several teleportation arrays to connect Tianshan and Lotus Mountain more closely, and then, he stayed in Tianshan and put all his mind on the Ten Thousand Immortal Array.

In the blink of an eye, thirty years have passed.

In the past thirty years, Tianshan Mountain has not been attacked from the Outer Heavens, and the Qinglian Sect has not been calculated by the Yin family again, and everything is very calm.

After thirty years of calm, Chang Shan relaxed and reconsidered the matter of improving his cultivation.

Now, Chang Shan has borrowed the power of the dragon vein to comprehend the earth's veins, and there is no need to measure the dragon veins, which undoubtedly saves him a lot of cultivation time.

However, if you are in retreat to understand the power of the leylines, it may still take hundreds or even thousands of years at a time.

After pondering for a while, Chang Shan decided not to retreat and cultivate the power of the leylines first, but to first comprehend the leyline refining technique in the "Zhenyuan Secret Record".

The Earth Leyline Refining Technique is a secret method that uses the power of the earth veins to help other earth practitioners cultivate and refine the true element and refine the physical body, and in the process of refining the true element and refining the physical body, it leads them to comprehend the mysteries of the power of the earth line.

Chang Shan happened to need such a secret method to help Yu Huanting and Chang Runyu improve their strength, and he carefully studied the earth's leyline refining technique back then.

However, since the leyline refining technique was one of the three most mysterious secret techniques in the "Zhenyuan Secret Record", he had been enlightened for several years, but he had nothing to gain, so he had to put this secret method aside for the time being.

Once again, he decided to pay attention to the earth's vein refining technique, Chang Shan thought about it for a while, and decided to go outside and use the spiritual vein as the test object to comprehend the earth's vein refining technique.

After explaining to the left to the south, Chang Shan came to an ordinary hill in the Ming Dynasty from the teleportation array.

The vast majority of spiritual veins, where the spiritual veins are located, the richness of the spiritual veins is related to the grade of the spiritual veins, and a very small number of spiritual veins, where the spiritual veins are located, may be a barren place, and such spiritual veins are called hidden spiritual veins.

Most of the hidden spirit veins are formed because of the existence of minerals similar to absolute spirit iron that are extremely resistant to spiritual power in the place where the spirit veins are located, and a small number of hidden spirit veins are formed because the location of the spirit veins happens to be a spiritual land.

Under this ordinary hill, where Changshan is located, there is a hidden spirit vein. The reason why this hidden spirit vein is a hidden spirit vein is because there is a layer of stone in the mountain that is extremely resistant to spiritual power.

"If there is no such stone body, will this spiritual vein grow into a medium-grade spiritual vein?"

The stone body has an obstructive effect on the spiritual veins to absorb spiritual power, and it also has an obstructive effect on the spiritual veins escaping spiritual power, and in the case of not knowing the effect of the stone body on the spiritual veins to breathe spiritual power, Chang Shan is unable to determine whether the stone body is beneficial or harmful to the growth of the spiritual veins.

Chang Shan pondered for a moment, then put the doubts that appeared in his mind at the back of his head, sat down cross-legged, and entered a state of merging with the earth under his feet, while studying the earth vein refining magic technique, while feeling the condition of the spiritual vein.

Time passed slowly, and when Chang Shan had some perception of the earth vein refining technique, he took the spiritual vein as the cultivator's meridian, the spiritual power in the spiritual vein as the cultivator's true element, and the mountain body affected by the spiritual vein as the cultivator's physical body, and tested the perception in his heart.

People are different, and even if they practice the same exercise, the nature of their true essence is also different.

The difficulty of the leyline refining technique is to fully grasp the nature of the true element of the casting object, and the difficulty is to ensure that the change of the true element of the casting object is completely beneficial.

For the spiritual vein, simply purifying the spiritual power in the spiritual vein is not beneficial to the spiritual vein, but the state that is completely beneficial to the spiritual vein is to increase the speed at which the spiritual vein breathes the earth's pulsation while purifying the spiritual power in the spiritual vein.

With a test subject, Chang Shan began to slowly begin to understand the mysteries of the leyline refining technique.

Time passed leisurely, and in a blink of an eye, another sixty years had passed.

After sixty years of enlightenment, Chang Shan has mastered the earth's leyline refining technique. However, for the sake of prudence, he still decided to find some demon beasts to exercise first, and then help Yu Huanting and Chang Runyu cultivate.

In today's land of seven states, in addition to the various secret realms, there are more demon beasts among the six mountains of Buzhou Mountain, Phantom Cloud Mountain, and Earth Four-legged.

Chang Shan first came to Buzhou Mountain from the teleportation array, and then went into the mountain to catch eighteen demon beasts that cultivated in the realm of five-grade demon beasts, returned to Tianshan, and exercised the earth's vein refining magic on them.

The types of demon beasts are different, the cultivation methods are different, and the true yuan of cultivation is not used.

By performing the Earth Vein Refining Technique on these eighteen demon beasts, Chang Shan has a certain amount of experience in completely grasping the nature of the spiritual power of a strange land.

The unexpected gain was that Chang Shan had mastered some of the innate skills of these eighteen demon beasts.

From this, Chang Shan realized that the leyline refining magic technique is not only to help others, but also to get some benefits in the process of helping others, and all kinds of strange secret methods in the "Zhenyuan Secret Record" may be obtained by Zhenyuan Daojun from some strange demon beasts with the earth's vein refining magic technique.

Chang Shan's comprehension of the earth's veins is to help Yu Huanting and Chang Runyu improve their strength, so although he had the intention of comprehending various earth-moving spells from various demon beasts, he came to the edge of Buzhou Mountain again, but he only released the eighteen demon beasts he caught.

Back in the Tianshan Mountains, Chang Shan explained to Huo'er, and then retreated to summarize the harvest of more than 70 years.

Chang Shan meditated for less than three months before he was woken up by Yu Huanting.

The two of them warmed up for a while, and Chang Shan told Yu Huanting about the earth's vein refining magic technique.

"I can't imagine that in addition to the dual cultivation method in this world, there is really a secret method to help others improve their perception and strength!"

When Chang Shan heard this, he was slightly stunned for a moment, and asked Yu Huanting, "In what classic books have you seen the legend of this secret method before?"

Yu Wanting shook her head and said with a smile: "In the past, my father had the strictest requirements for the second brother, but the second brother was always a little tired of cultivation, and he would always give birth to a lot of unrealistic fantasies. ”

"Many secret methods were created by fantasy. ”

Chang Shan answered with a smile, his mind turned, he looked at Yu Wanting and said, "The second brother is tired in cultivation, this is probably related to the fact that his father-in-law is a little strict with him!"

Yu Wanting nodded, sighed lightly, and said, "The second brother wants to inherit the position of the palace master, and my father has to be strict with him. ”

She replied, and suddenly thought of Chang Chongyu.

"Chongyu's attitude towards cultivation is exactly the opposite of that of the second brother, which is probably related to your attitude towards Chongyu and the opposite of your father's attitude towards the second brother. ”

Chang Shan shook his head and said with a smile: "It may have something to do with it, but it doesn't matter much, Chongyu didn't have any resistance to becoming a formation cultivator back then." ”

"Isn't that because you didn't push him at all?"

"That's right!"

After chatting for a while, Chang Shan brought up the matter of the leyline refining magic again.

Chang Shan and Yu Huanting sat opposite each other, and when Yu Huanting completely calmed down, he controlled his true yuan to vibrate, and used his true yuan to drive Yu Huanting's true yuan to vibrate.

The nature of a high-grade spiritual vein is not exactly the same as that of the main spiritual vein and the branch spiritual vein, but their properties are beneficial to their respective growth and the growth of their respective regions.

The Earth Vein Refining Technique was created from the characteristic of high-grade spiritual veins.

Chang Shan regarded himself as a main spiritual vein, and regarded Yu Huanting as a place where spiritual veins were being formed but did not form spiritual veins, and then used his influence on Yu Huanting to help Yu Huanting quickly give birth to a spiritual vein suitable for herself.

In a trance, Chang Shan entered a wonderful state, breathed according to the way the earth breathed, and guided Yu Huanting to breathe according to the way the earth breathed.

I don't know how long it took, Chang Shan and Yu Huanting woke up from their cultivation at the same time.

As soon as he came to his senses, Chang Shan found that Yu Huanting's breath was obviously condensed a lot.

Chang Shan used the Earth Vein Refining Technique for the first time to help Yu Huanting cultivate, and the effect was surprisingly good.

"The strength has really improved a lot!"

Yu Huanting felt her own strength, leaned over, and kissed Chang Shan lightly on the face.

"Thank you, husband!"

Chang Shan was also very happy in his heart, but after thinking about it, he still said: "The Earth Vein Refining Divine Technique, just like the elixir, the first time you use it, the effect is the best, and I am afraid that it will not have such a good effect in the future." ”

When Yu Huanting heard this, she glanced at Chang Shan and said with a smile: "Is the husband afraid that Yu'er will slack off in cultivation?"

Chang Shan nodded and said softly: "Husband is really a little scared!"

Yu Wanting was stunned for a moment, leaned into Chang Shan's arms, and said softly: "Husband, don't worry, although Yu'er's cultivation talent is not as good as yours, she should be able to survive the sixth heavenly tribulation and accompany you for tens of thousands of years." ”

After saving for a while, Yu Huanting thought of Chang Runyu and Chang Chongyu, and said softly: "Husband, when will you help Runyu and Chongyu improve their strength?"

Chang Shan thought for a moment and muttered, "Chongyu is afraid that he won't want me to interfere in his cultivation, as for Runyu, let's wait until she crosses the sixth Heavenly Tribulation and then help her with the Earth Vein Refining Divine Technique!"

Yu Wanting thought for a while and said softly: "That's fine! Runyu hasn't experienced much danger, and helping her improve her strength with external forces will definitely make her dependent on external forces." ”

The two discussed, and Chang Shan did not use the leyline refining magic to help Yu Huanting again, but accompanied Yu Huanting to practice various spells to help her become familiar with her own improved strength.

A hundred years passed in an instant, and when the leyline refining technique did not have much effect on Yu Huanting, Chang Shan left the Tianshan Mountains and came to the Lotus Mountain.

The Qinglian Sect's scruples about the Tianli royal family are like Chang Shan's scruples about the Qingdi.

Although the Tianli royal family had completely exposed its wolf ambitions for the Qinglian Sect back then, under the condition that the Tianli royal family took the initiative to make friends, the relationship between the Qinglian Sect and the Tianli royal family has now returned to the past.

In the matter of the Tianli royal family's plot to seize the Lotus Mountain, the Tianli royal family and the Qinglian Sect did not have any losses, and now they are even more relieved, but the Zhitian Sword Sect and the Kunwu faction have suffered losses that have nothing to do with this matter, which cannot but be said to be a great irony.

Chang Shan stayed in the Blue Lotus Sect for seven years, went to the depths of the Boundless Sea to help the Blue Lotus Sect establish a secret foundation, and then left the Lotus Mountain.

After returning to Tianshan and explaining, Chang Shan came to Cangyi Mountain.
