"Senior brother, how could a ninth-order demon beast come over to save the Zhen family's mother and daughter? This is completely unreasonable?" Murong Cheng had an expression of disbelief, the relationship between the human cultivator and the demon beast had always been hostile.

"Sect Master, I can't figure this out either. Ji Jiantong shook his head.

"For us, this Zhen mother and daughter are not very important roles, now that we think about it, we are still a little afraid, if the Green Scale Demon Jiao wanted to kill us at that time, we are afraid that we will not be able to stop it. Murong Cheng looked happy.

"Sect Master, the Mountain Protection Array must be repaired as soon as possible to prevent that demon Jiao from going and returning. Ji Jiantong suggested.

Suddenly, Murong Cheng thought of an extremely important matter.

"Oh no! we may have fallen for the monster's plan, so let's go to the Purgatory Prison. Murong Cheng shouted.

Murong Cheng and Ji Jiantong hurried to the Purgatory Heavenly Prison, and when they entered the Heavenly Prison, they saw that "Zhang Zijin" was still there, which made the two of them feel a little at ease.

"This time the mountain protection array was destroyed, and our Yin Corpse Sect suffered heavy losses, and these have to be counted on the head of the Demon Refining Sect. When it comes forward to negotiate with the Demon Refining Sect, I ask Senior Brother to bother more! With their Supreme Elder's grandson in our hands, the initiative is in our hands. Murong Cheng said.

Great Elder Ji Jiantong nodded.

Murong Cheng and the others made sure that they didn't find anything out of the ordinary, and left the Purgatory Prison.

At this moment, Lu Chen clicked on himself a few times, and the prohibitions laid by the previous Yuan Infant Great Perfection Cultivators were instantly broken.

"Sealing Spirit Array!"

"Sealing Spirit Array!"

Isn't it just to seal the spiritual energy to prevent leakage? Under this purgatory heavenly prison should be where the spiritual veins of the Yin Corpse Sect are located, thinking of this, Lu Chen couldn't help but feel a burst of excitement in his heart, the Yin Corpse Sect has a long heritage, and the grade of the spiritual veins selected must be good, and for his Zhenxian Pagoda, it may be an opportunity to improve the grade.

With Lu Chen's current formation attainments, it is not too difficult to arrange or crack an eighth-order formation.

Lu Chen integrated all his mind into the formation and began to deduce day and night.

Ten days later, the Green Scale Demon Jiao carried Zhen Xiaofu's mother and daughter to the gate of the Demon Refining Sect safely.

For Zhen Xiaofu's mother and daughter, this trip was a death-defying trip, and because of Lu Chen, they were able to regain their freedom.

After Zhang Taihe received the report from the disciples who guarded the mountain, he immediately rushed over with his grandson Zhang Zijin and the high-ranking officials of the sect.

It was the first time for Zhang Taihe and the elders of the sect to see the blue-scaled demon Jiao, and they were fortunate enough to see this legendary ninth-order demon beast, and the monks present were all in a surging mood.

Zhang Taihe led the cultivators of the Demon Refining Sect to bow down to the Green Scale Demon Jiao, and the Green Scale Demon Jiao nodded to everyone, and then flew into the sky and disappeared from everyone's field of vision in an instant.

"Meet Elder Taishang!" Zhen Siniang's mother and daughter bowed to Zhang Tai and Ying Ying.

"It's good to be back!" Zhang Taihe said with a smile.

"Brother Zhang, I'm back!" Zhen Xiaofu thought that she would never see Zhang Zijin again, but for the rest of her life, she suddenly threw herself into Zhang Zijin's arms and cried with a whimper.

"Siniang, Lu Chen's fellow Daoist is in the Yin Corpse Sect

How's it going?" asked Zhang Taihe.

"Elder Qiyu, according to the little girl, the Yin Corpse Sect locked Senior Lu in a place called Purgatory Heavenly Prison. Zhen Siniang said.

"Purgatory Heavenly Prison?" Zhang Taihe's face changed, it was a place where the monks in the early stage of the Transformation of God did not dare to stay, and he couldn't help but worry about Lu Chen's safety in his heart.

"Elders, Lu Chen's fellow Daoist has risked his life for my Demon Refining Sect, it can be said that he has a great favor to my Demon Refining Sect, our Demon Refining Sect must not do something ungrateful, this seat has decided to devote the strength of the entire sect to fight to the death with the Yin Corpse Sect!" Zhang Taihe said.

"Fight to the death!"

"Fight to the death!"

"Fight to the death!"

Early the next morning, under the leadership of Elder Taishang Zhang Taihe, the Demon Refining Sect set out and went straight to the Yin Corpse Sect.

Inside the Purgatory Heavenly Prison of the Yin Corpse Sect.

After half a month of sleepless deduction, Lu Chen finally succeeded in breaking the eighth-order phantom array and the eighth-order spirit sealing array in the heavenly prison.

At the moment when the eighth-order spirit sealing array disappeared, the aura of the entire Purgatory Heavenly Prison was extremely strong, Lu Chen hurriedly sacrificed the Zhenxian Pagoda and smashed it to the ground of the Heavenly Prison, and a large pit about a hundred zhang deep appeared at Lu Chen's feet, with nine pillars of spiritual energy shining white light standing.

Normally, gray-white is the low-grade spiritual vein, pure white is the medium-grade spiritual vein, milky white is the high-grade spiritual vein, and the jade transparent color belongs to the legendary superlative spiritual vein.

The spiritual vein of the Yin Corpse Sect was a complete medium-grade spiritual vein, which made Lu Chen overjoyed.

Under the control of Lu Chen's mind, the Zhenxian Pagoda quickly flew above the spiritual veins, circling around the nine spiritual light pillars, and after a few breaths, an extremely strong suction force suddenly rushed out of the tower, covering the entire spiritual vein land.

In an instant, endless spiritual energy surged towards the body of the tower, and was sucked into the tower by the suction emitted by the Zhenxian Tower.

At the same time, the pit where the Spirit Vein Land was located sank deeper and deeper, and countless gravel and earth fell down in unison, as if a huge earthquake had occurred.

"Boom!"

The prison of Purgatory shook more and more violently, as if it would collapse at any moment.

The Zhenxian Pagoda kept spinning in the air, and Lu Chen's mind was immersed in the tower, controlling the Zhenxian Pagoda to speed up the absorption of the power of refining spiritual veins.

After a while, the power of the spiritual veins contained in the entire spiritual vein turned into a series of lines on the inner wall of the Zhenxian Tower, and a rich aura gushed out from these lines, at this moment, the Zhenxian Pagoda completely refined the middle-grade spiritual vein of the Yin Corpse Sect, and the grade of the Zhenxian Pagoda evolved from the eighth-order magic weapon to the ninth-order magic weapon at once, and the current Zhenxian Pagoda can kill a mid-stage cultivator of the Transformation God with one blow.

With the disappearance of the mid-grade spiritual vein, the rich spiritual energy in the entire Yin Corpse Sect suddenly became barren to the extreme, and all the monks had to stop cultivating, and everyone walked out of the house one after another, not knowing what was going on.

The aura became thinner, it must have been a change in the spiritual vein, and the Yin Corpse Sect Sect Sect Leader Murong Cheng and Supreme Elder Ji Jiantong rushed to the Purgatory Heavenly Prison as quickly as possible.

At the entrance of the Purgatory Heavenly Prison, the two glanced at each other and offered magic weapons very tacitly

, cautiously walked in.

As soon as they entered the Purgatory Heavenly Prison, they found that the Eighth Order Phantom Array and the Sealing Spirit Great Array had stopped operating, which made the two of them sink in their hearts, and the next scene they saw made these two most respected monks in the Yin Corpse Sect can't help but burst into blue muscles, and their eyes widen in anger, only to see that the ground of the Purgatory Heavenly Prison has been smashed out of a big hole, through the big hole, they found that the foundation of the Yin Corpse Sect, the entire middle-grade spiritual vein, has disappeared.

Without the spiritual vein, it won't take much time for the Yin Corpse Sect to decline.
