Although it was his own choice to change to ghost cultivation, however, his physical body was gone and he had become a yin ghost, and he was still a little lost, just like when Chang Shan knew that he was a zombie.

After Wan Zijing finished talking about the process of transforming into a heavenly ghost, he was silent for a moment, and said to Chang Shan: "Don't disturb Engong, the old slave has gone to cultivate." ”

"Hmm!"

After Wan Zijing returned to the stone room where he was before, Chang Shan pondered for a moment, put away the almost quenched dark iron on the earth's fire, came outside, took out the nine array flags that he had put away at the beginning, confessed the lord with blood, threw out the nine array flags, and hid the gate of the Ghost King's Mansion again.

Two years ago, Chang Shan should have hidden the gate of the Ghost King's Mansion before he started refining the Yin Mine, but what he saw and what happened after entering the Ghost King's Mansion made him forget to hide the gate of the Ghost King's Mansion for a while.

Back in the refining room, Chang Shan frowned and looked at the Earth Fire and pondered for a moment, then took out eight array flags and laid out the Fire Spirit Array around the Earth Fire Eye.

In the stone room, the aura of fire is relatively strong, but the fire spirit array laid by Changshan mainly affects the earth fire in the eyes of the earth fire.

Chang Shan laid down the Fire Spirit Array for a while, and as soon as his mind moved, the Earth Fire in the Earth Fire Eyes suddenly shrank a lot, the color was obviously a little brighter, and the power was also significantly enhanced.

"It works!"

With a flash of light in his eyes, Chang Shan continued to quench the piece of dark iron that had been quenched for two years in the earth fire, and then took out all the other yin ores on his body and refined them in the earth fire.

Among the four materials for refining the Soul Suppression Tower, the power of heavenly thunder, Yin Spring Water, and Fragrant Soul Wood did not need to be quenched, and after spending three years melting all the Yin Ore into a dark silver mass, Chang Shan planned to start refining the Soul Suppression Tower.

"Refining the Soul Suppression Tower doesn't need earth fire, it's better to go to the alchemy room to refine, most of the pills there seem to be used to restore the power of the primordial gods. ”

Thinking about it, Chang Shan moved his mind, summoned the dark silver yin ore in the earth fire, controlled it to levitate in front of him with his mind, and walked out of the refining room.

Out of the refining room, Chang Shan saw the fragrant fir tree, his heart moved, and he said secretly: "There is also a fragrant soul wood in that fragrant fir tree, it is better to use that fragrant soul wood!"

After pondering for a moment, Chang Shan thought that the fragrant fir tree was full of vitality, and the fragrant soul wood in it might not be fully ripe, so he dispelled this thought.

"Anyway, that fragrant soul wood hairpin is useless to me, so let's use it!"

Chang Shan thought like this in his heart, and the appearance of Princess Mingyu appeared in his mind again.

His brows furrowed slightly, Chang Shan suppressed the thoughts that appeared in his heart, and his body moved, flashing to the door of the alchemy room.

Chang Shan walked into the alchemy room, moved the Danding placed in the center of the alchemy room to the side with True Yuan, then sat down opposite the door, took a deep breath, and summoned the soul fire to calcinate the dark silver yin mine.

After Chang Shan calcined the dark silver yin ore with soul fire for a year, the dark silver yin ore turned into a colorless transparent crystal-like thing.

With a flash of light in his eyes, Chang Shan controlled the colorless transparent crystal-like thing to turn into a bell-shaped thing with a lid on the top.

There is a common understanding in the cultivation world that cultivators can gain strong strength through cultivation, and all weapons and magic weapons can become more powerful after being nourished by spiritual energy for a long time.

However, despite this understanding in the cultivation world, after most weapons and magic weapons are refined, their quality will not change much before they are destroyed, because the speed at which weapons and magic weapons absorb aura is much slower than that of cultivators, and when cultivators become more powerful, they will find or refine more powerful weapons and magic weapons, and will not spend time slowly recuperating the weapons and magic weapons they originally used.

In the cultivation world, there are some weapons and magic weapons, after refining them, their owners will use various methods in the process of cultivation in the future to make their power increase at the same rate as their own cultivation, this kind of weapons and magic weapons are the so-called natal weapons and natal magic weapons.

The immortal sword of sword cultivation is a natal weapon, and it is also a natal magic weapon, and the two magic weapons recorded in the "Soul Sutra", the Ten Thousand Ghost Banner and the Soul Suppression Tower, are also natal magic weapons.

The power of the Ten Thousand Ghost Banner is related to the number and strength of the Yin Ghost in the Ten Thousand Ghost Banner, and the greater the number of Yin Ghosts in the Ten Thousand Ghost Banner, the greater the power of the Yin Ghost Banner in the Ten Thousand Ghost Banner, and the higher the grade.

The power of the Soul Tower is related to the number of layers, and the higher the number of layers, the more powerful it is.

Different from the pagoda in Changshan, the Soul Suppression Pagoda is a kind of pagoda with a small tower in a large tower, and the two-story Soul Suppression Pagoda is like a big bell with a small bell.

The refining method of the Soul Suppression Tower is different from the general magic weapon, when the Soul Suppression Tower is first refined, there is only one layer, however, the quality of the materials for refining the Soul Suppression Tower is not too bad, then, with a little cultivation, the second and third layers will soon appear in the Soul Suppression Tower, becoming a high-grade spiritual weapon, and if the material quality is good enough, it is also possible that the fourth layer will appear and become a low-grade immortal weapon.

After controlling the Yin Mine with his mind and turning it into a special pagoda, Chang Shan's mind moved, and two jade bottles appeared in front of him.

Chang Shan first controlled a jade bottle to fly above the Yin Spring, collected a whole bottle of Yin Spring Water, and then poured the Yin Spring Water on the pagoda while controlling the pagoda to absorb the Yin Cold Qi in the Yin Spring Water.

This process contains the subtlety of Jin Shengshui.

When the whole pagoda turned blue, Chang Shan first calcined the pagoda with soul fire for several days, and then took out the jade box containing the fragrant soul wood, shattered the fragrant soul wood into wood powder, sprinkled it on the pagoda, and smelted the wood powder into the pagoda with soul fire, at this time, the pagoda turned cyan.

The cyan pagoda was also calcined with soul fire for several days, and Chang Shan took out all the lightning strike wood, shattered one by one, released the power of heavenly thunder in it, and refined it into the pagoda with soul fire.

The closer the spiritual power of the four materials in the refining soul tower is, the easier it is to refine.

If the spiritual power of the four materials is quite different, then the person refining the pagoda needs to use the subtlety of the transformation of the five elements of yin and yang to adjust the spiritual power of the four materials to the extent that they can be arrayed.

During the three years of refining the dark iron, although Chang Shan failed to deduce the Yin and Yang Five Elements Reincarnation Array and the Yin and Yang Five Elements Soul Nourishing Array, he also grasped some of the subtleties of the transformation of the Yin and Yang Five Elements, and at this time, it was not too difficult to use his understanding of the way of the Yin and Yang Five Elements to adjust the spiritual power of the four materials in the pagoda.

At the same time as the spiritual power of the four materials, Chang Shan also refined part of his Yuan Shen power into the pagoda to supplement the lack of earth power in the five elements.

When the spiritual power in the pagoda reached the balance of the five elements of yin and yang, Chang Shan began to condense the formation in the pagoda.

Among the five formations in the Soul Suppression Tower, the role of the Yin and Yang Five Elements Soul Nourishing Array is to warm and nourish the Yuan Shen, the role of the Yin and Yang Five Elements Reincarnation Array is to resist the attack of the Yuan Shen, and the role of the other three formations is similar to the role of the Tianyin Great Array in the Ten Thousand Ghost Banners, however, the Tianyin Great Array focuses on storing and controlling the Yin ghosts, and the three formations in the Soul Suppression Tower focus on refining the power of the Yin ghosts into a special power of the Five Elements to warm and nourish the Soul Suppression Tower.

Of the five formations, the first thing to be condensed in the pagoda is the Yin and Yang Five Elements Soul Nourishing Array.

Although Chang Shan had not yet been able to fully deduce the Yin and Yang Five Elements Soul Cultivation Array, he relied on his attainments in the Five Elements Array and successfully condensed the Yin and Yang Five Elements Soul Cultivation Array in the pagoda.

After arranging the Yin and Yang Five Elements Soul Nourishing Array, Chang Shan spent another three months arranging the Five Elements Array Sealing Array, the Five Elements Soul Refining Array, and the Five Elements Soul Summoning Array in the pagoda, and then began to condense the most difficult to understand Yin and Yang Five Elements Reincarnation Array in the pagoda.

Chang Shan first used the method of condensing the Yin and Yang Five Elements Soul Nourishing Array to condense the Yin and Yang Five Elements Reincarnation Array, and after failing, he pondered for a few days and couldn't think of a good way, so he continued to condense the Yin and Yang Five Elements Reincarnation Array by condensing the Yin and Yang Five Elements Array .

Mostly relying on luck, it took Chang Shan three years to condense the Yin and Yang Five Elements Reincarnation Array in the pagoda.

After condensing the Yin and Yang Five Elements Reincarnation Array, the Soul Suppression Tower has already been successfully refined.

Since Chang Shan is the constitution of the Five Elements Partial Earth, the soul tower he refined was the same color as his primordial god, which was dark gold.

"You have been refined without any mistakes, and all these years of hard work have not been wasted. ”

Taking a deep breath, Chang Shan took the Soul Suppression Tower into Zhihai.

As soon as the Soul Suppression Tower entered the sea of knowledge, it covered Chang Shan's soul beads.

While Chang Shan was concentrating on restoring the power of the original gods, some wonderful changes took place in the Soul Suppression Tower.

A month later, the Tower of Soul Suppression doubled in height, and there was a small tower inside that was identical to the one outside, and the inner tower and the outer tower were connected by five pillars of different colors.

The Soul Tower is dark gold, and the five pillars are white-gold, cyan, azure, purple, and dark gold.

After another month, the Soul Suppression Tower doubled in height, and another layer passed inside, changing from a medium-grade spiritual weapon to a high-grade spiritual weapon.

After another nine months, the Soul Suppression Tower was once again increased by one layer, and the Soul Suppression Tower became four floors, from a high-grade spiritual weapon to a low-grade immortal weapon.

At this time, the spiritual power in the Soul Suppression Tower calmed down, and Chang Shan, who had fully recovered the power of the Yuan Shen and had made considerable progress, woke up from his cultivation.

As soon as Chang Shan opened his eyes, he closed his eyes again, sank his consciousness into the sea of knowledge, and observed the Soul Suppression Tower.

Although the quality of the materials used by Chang Shan to refine the Soul Suppression Tower was not bad, he was still somewhat surprised to see that the Soul Suppression Tower had four floors.

"If it weren't for the replacement of ordinary soul-nourishing wood with fragrant soul wood, I am afraid that the soul suppression tower refined would not have four layers, and it would be considered luck to be able to refine a four-story soul suppression tower. ”

Thinking about it, Chang Shan walked out of the alchemy room.

Dodging to the stone room where Wan Zijing was retreating, Chang Shan wanted to use the power of the Yuan Shen to investigate Wan Zijing's situation, but hesitated, worried that it would affect Wan Zijing's cultivation, so he gave up.

"I don't know when he'll be out of the country?"

After pondering for a moment, Chang Shan returned to the refining room and deduced the fire spirit array beside the fire spirit.
