The valley where the Zhenyin Tower is located, sits in the north and faces south, surrounded by three mountains on all sides, the middle sinks, the woods on the mountain are dense, from a distance, the whole tower body seems to be submerged in the ground, this is a feng shui pattern of the sunken corpse.

Zhang Xian learned the necrosis taught by Xiaoyun, and also learned the inheritance of the Meng family, and had a certain understanding of Feng Shui Kanyu and Shengji burial methods, and recognized the pattern of this Zhenyin Tower at a glance.

The place of the sunken corpse is a valley sandwiched between two mountains, the two mountains are located on the east and west sides, blocking the yang energy of the sun, the valley is damp, and there is a mountain in front of the valley, blocking the feng shui of the valley, so that the earth qi can not circulate, and the mountain is higher, the qi is silted in the valley, and can only sink to the ground.

And the valley is densely wooded, when it rains, the mountain cement soil and dead branches and leaves slide down, piled up in the valley, the thicker the cover, if the corpse is buried here, as if it sinks into the ground, so it is called the sinking corpse ground.

The corpse sinking ground is divided into two kinds, one is Yang Shen, commonly known as Yin Gan, Yin Qi descends, leaving Yang shape, suitable for burying dry corpses, and immortal for a long time.

The other is gloomy, the Zhenyin Tower is gloomy, damp and silted, the Yin Si is heavy, suitable for burying the wet corpse, and the training corpse also belongs to the wet corpse, this Zhenyin Tower is a feng shui treasure for practicing the corpse.

He stared at it, his eyes had heavy pupils, looked at yin and yang, looked directly at the truth, and saw at a glance that under the Zhenyin Tower, tens of thousands of corpses were buried, which was completely a mass grave pit, and the tens of thousands of people were all buried alive under the tower.

At the bottom of the tower is a layer of underground palace, there are a lot of coffins, there are several of them, the coffins are full of training corpses, nourished by the resentment of the Yin Si underground, all of them are copper corpses, among which there are five silver corpses, which are practiced with the corpses of the masters of Baodan.

Two of these five silver corpses were the same ones that had fought with the Great Elder of the Yin Jar last time, and the corpse souls were broken by him, and now the corpse souls were reunited.

As for the other three, I don't know if they were newly practiced in the past two years, or if they were originally from the Yin Urn Sect.

And this total of five silver corpses, under the cultivation of the huge yin qi of this mass grave, the qi is extremely strong, like five ghosts, gods and demons, and their power far exceeds that of the last time they met, and even Kenbi ghosts and immortals.

And after checking it, he also found a suspicious point, tens of thousands of people buried alive at the bottom of the tower, most of the corpses did not decompose, but the corpses became a little shriveled, like a dried corpse.

However, the feng shui of this place is a place of yin corpses, and it is impossible to bury wet corpses, not dry corpses.

"There must be a demon when things go wrong, and there must be something wrong with these corpses. ”

He gathered his eyes and wanted to take a closer look, but the corpse was buried in the soil under the underground palace, and the barrier of the soil layer was too deep, even though he had already begun to open the valley, be reborn, and make great progress, but he could only see the shadow of the corpse, and he couldn't see the specific things clearly, unless the corpse was dug up.

However, this Zhenyin Tower is also combined with feng shui, a formation, the earth's vein aura is clear, and the earth escape technique cannot escape into it, and the body can only be made by digging up the underground palace.

He turned his gaze to check the guards in the tower, and sure enough, as he expected, the Great Elder of the Yin Urn lived here and sat down, and his aura was the most powerful, and he recognized it at a glance.

I haven't seen each other for two years, and the Great Elder Yin has greatly improved his Taoism, and he is now practicing in the ashram at the top of the tower.

And he found that the Great Elder's flesh and blood were active, the red light was restrained and thick, and the bone marrow on his back exuded a strong bright red, as vigorous as a young man.

"It's strange, two years ago, I saw the qi and blood of the Great Elder of the Yin Urn, it was not so bright red, and the ghost immortal cultivating the Yin God needs to absorb the yang spirit of the flesh, and the qi and blood of the flesh will only get older and older, how can it be rejuvenated, but become younger?"

He felt puzzled, and checked the others, in the entire tower, there were not many people, only about thirty, you can tell by looking at the clothes, all of them are disciples of the Gu family, one of them is returning to the void and holding the pill, and the other has a few practicing qi and transforming gods, and the rest of the people are very ordinary.

"It seems that the strength of the Yin Urn Sect is not strong, and there are only a few masters. ”

He checked Second Uncle Gu's thoughts, and knew the situation of the Gu family, some people who had escaped by luck back then, after decades of dormancy, they did not recover, and only these people were the only ones.

But the strange thing is that this Bao Dan Realm is also a middle-aged man, already forty or fifty years old, Bao Dan is not perfect, there is no Bigu reborn, it stands to reason that the qi and blood should also be dim, but this person's qi and blood red light, like the Great Elder, is also bright red, like a young man.

And this person is also in retreat, looking at the trend, Bao Dan is about to be consummated, and he is about to start Bigu.

"Over thirty years old, aging qi and blood, holding Dan is hopeless for life, it is already good to be able to maintain the realm without retreating, but this person is already forty or fifty years old, and he can still hold Dan to progress, could it be that the Yin Sect has a secret method to reverse qi and blood?

While speculating in his heart, he searched the storehouse in the tower, and soon found that the storehouse was on the first floor of the tower.

This Zhenyin Tower has a total of four floors, a basement underground palace, this is the main part of the Zhenyin Tower, used to practice corpses, the area is very large, deep underground, there are three floors on the ground, the whole is tower-shaped, the first layer is connected with the underground palace, all with stone buildings, like a stone palace, and the stone wall is very thick, it is difficult to escape into the ground.

The treasury is in the stone palace on this floor, and the treasury stores a lot of gold and silver, as well as various medicinal materials and bottles and jars, as well as spiritual jade and spiritual wood.

On the stone palace is a two-story courtyard attic, where the disciples of the Gu family live on the first floor and the great elders live on the second floor.

There is only one entrance to the stone palace, located in the center of the first floor, just behind the retreat of the Baodan realm, this person practices here, and he also specializes in guarding the entrance, and the entrance is also arranged with a talisman formation.

The route to enter the Stone Palace is to walk up to the first floor from the steps of the Stone Palace, through the passage, through the guarded Baodan Realm, and then go down to the Stone Palace.

"If you want to enter through the entrance without knowing it, it is almost impossible, if you break in, you will inevitably be resisted, but you can't kill it, otherwise it will lead to Yang Xian, which will be troublesome. ”

"Unless you lure people out, sneak in, steal things, and then force them out. ”

"But this fighting method, I'm afraid it's not easy, there are hundreds of bronze corpses underground, and five silver corpses, if you use Dao Soldier Spells to unify the power of these corpses, this power is not small. ”

The last time he fought with the Great Elder, the Great Elder controlled two silver corpses, which the Immortal Family called the Dao Soldier Spell.

The Taoist soldiers are the soldiers under the immortals, linked together by spells, arranged in formation, neatly aligned, these physical strength of the corpse is not to be feared, lack of flexibility, and it is difficult to fight with the real master, but the corpse soul is one, and this power is very powerful.

And the mass grave under this underground palace is also a formation, and it is here to fight with the Yin Urn faction, unless it is a Yang Immortal master.

Thinking about this, he couldn't help frowning, he came all the way, and he was full of confidence to find the evil man's fighting method, if he went back like this, he was really a little depressed.

He carefully observed the deployment of the guards in the tower, there were not many disciples of the Gu family, there were only about thirty people, there were corpses in the underground palace, and there was a large array of mass graves underground, surrounded by corpses and bones on all sides, and there was no need to guard at all.

There were five or six patrols in the stone palace on the first floor, in groups of individuals, with several corpses.

There were also five or six people patrolling the first floor of the stone palace, each carrying a few corpses, and shaking bells to drive away the corpses as they walked.

There was no patrol on the second floor, and the Great Elder himself lived on the second floor.

The number of guards is not large, and the way is very shallow, but one person is a group, and they keep ringing the bell, and if they do it, the sound of the bell will be chaotic, and others can hear it.

"It's not difficult to bypass these patrols, but you still have to enter through the entrance, there are talismans at the entrance, and there are Baodan masters guarding it, it's difficult to pass, but it's ......"

He had an idea, why did he have to enter through the entrance, although the walls of the stone palace were thick, he could chisel the wall open, as long as he chiseled a crack, he could enter through the wall, wouldn't he be unaware.

With his current strength, chiseling stones is like chiseling tofu, and it is not effortless at all.

He took out the bottle inside, whispered a spell, and poured out a flying sword.

This flying sword is a foot long, the whole body is cast by Vajra, the sword body is thick, the sword is sharp, and it seems to penetrate the object very much, this Vajra flying sword was obtained by killing the Protector Venerable of the Lotus Sect, and he has always carried it on his body.

"Let's do it tonight. ”

He had made up his mind, it was still early in the morning, and he continued to watch the situation in the tower.

On the second floor of the Zhenyin Tower, in the quiet room, the Great Elder of the Yin Urn meditated and practiced as always, closing his eyes and concentrating, motionless, completely unaware that someone was peeping in the dark.

I don't know how long it took, but a gust of yin wind swept by, and the yin god returned to his place.

The Great Elder opened his eyes, a ray of light flashed in his eyes, and then he was restrained and calm, with joy on his face, just now he was out of his body, and he was already able to fly out of a hundred miles.

Cast thousands of miles away, this is shuttling through the underworld, the underworld is the back of the yang world, the invisible substance has no distance, and the yin god travels, this is flying in the yang world, there is a tangible and qualitative distance.

Flying out of a hundred miles, this is the manifestation of the Yin God Dacheng.

"This marrow tonic pill is really mysterious, it can actually bring the qi and blood back to the vitality of the youth, in just a few years, it has actually cultivated to the upper level of the Yin Immortal, and the qi and blood are endless, if you continue to take it for a few more years, it is enough to be comparable to a Yin Immortal. ”

The Great Elder pondered in his heart, glanced at the sky outside, it was already afternoon, took out a bottle, poured out a pill and took it, only to feel that his whole body was full of qi and blood, and continued to enter the meditation practice.

This marrow tonic pill was obtained by Uncle Taishi from the Heavenly Gate, which can replenish the bone marrow and rejuvenate the qi and blood, just like a young man.

Originally, the Great Elder Bao Dan was not perfect, but a few years ago, Gu Yingtian was reincarnated and returned to the throne, and he first found the Great Elder, who was cultivated by Gu Yuntian and gave him the marrow tonifying pill.

And this marrow tonic pill is one of the elixirs of life recorded in the "Yin and Yang Secret Record", which is refined by the master of Tianmen Sect.

The Great Elder has been taking the Tonifying Pill, and then he has completed the pill, and then he has become a ghost immortal, and he has been taking it until now, and he has been improving, and the ghost immortal has become a great achievement.

On the cliff, Zhang Xian kept looking at the tower, only to see the great elder taking the pill, the pill melted in the body, the qi and blood were active, the bone marrow emitted bright red blood, and the body was full of vitality, as if taking a big tonic.

"Hmm, what kind of elixir is this, could it be that the Great Elder just took this medicine and reversed the aging of the yang spirit? But this medicine, why does it look a little familiar?"

He was very curious in his heart, the effect of this elixir is mysterious, it greatly replenishes the marrow and blood, reverses aging, if there is this elixir during the Bigu period, it will definitely make the foundation of the body stronger.

But this elixir, he felt that he had seen it somewhere, and after thinking about it carefully, he couldn't help but have his eyes jump: "Lotus Sect!"
