Back in Gushan, Gu Changsheng said hello to Bai Ruoxi, and then went back to his residence to meditate by the bedside, planning the arrangement of the 'Eight Desolations and Six Formations' in his heart.

He also planned to open a secret cave in this large array, making it the control center of the 'Eight Desolations and Six Arrays'.

Of course, Gu Changsheng didn't want to tell the truth about Gu Feichen and Bai Ruoxi's words, and the two of them wouldn't know that they had secretly moved their hands and feet in the big array.

On the one hand, they are afraid that the two will accidentally reveal the truth and be taken advantage of by the bad guys. On the other hand, it is also for the sake of the two of them, if they don't know the secrets of this big array, they won't be lucky and do something against the way of heaven. After all, only with reverence can we stay calm in this troubled world, and if we are arrogant, we will easily go down the wrong path.

And he also plans to build an alchemy room, a refining room and a medicine garden in the cave.

The small Dan furnace he carried with him earlier had already become an exclusive storage for corpse fire, and had been refined into the array flag by him earlier, becoming a weapon to kill enemies.

Moreover, in order to refine the pill in batches, a mouthful of a larger and better quality medicine pod is also needed.

Let's build the Danfang first, and then go to the various markets.

Good medicine can be met but not sought, this can only be done by luck!

Danfang, he actually had this idea when he first came to Gushan, but he has been a little hesitant.

The large array of this medicine garden is really too fragile.

From the isolation formation covering these tiled houses, to the chain of large arrays in the Gu family's medicine garden, to the core formation of grandpa's secret room, they are actually ordinary and have nothing unique.

And to build a Dan room, the movement of the alchemy process will not be small, and it will inevitably make people with intentions target, relying on Gu Feichen and Bai Ruoxi will not be able to withstand the enemy's attack at all.

But if you can build a 'Eight Desolations and Liuhe Great Array', you will basically have peace of mind - at least if the enemy enters the Great Array, he will be killed immediately, and he can automatically destroy the corpse!

"The Danfang should not be too close to the residence, lest any poisonous gas leak ......"

Gu Changsheng muttered in a low voice and found a thick stack of white paper.

Draw a formation diagram and building structure diagram on it, each one is done in one go, this large array has been laid out many times in the fairy world, and he has already memorized all the details.

The mainstream formations are all based on all kinds of treasure materials, spirit stones, and specially refined treasures, and the bases are connected to each other to form large arrays with different effects.

The way of the formation is broad and profound, and Gu Changsheng thinks that he has realized the essence of it.

About six or seven thousand years ago, Gu Changsheng studied the remaining formations of the Immortal Sect in his spare time when he practiced, and accidentally found that most of the common formations in the mainstream of the Immortal Realm were distributed on a horizontal plane.

And there are always some wild ideas in his mind, and the realization of these ideas one by one in the immortal gate under his protection has been repeatedly verified.

The most important thing in the formation is to adapt measures to local conditions, the place where the yin and fierce is covered with a lost ghost array, the place where the earth's veins are strong is a protective array, the land of the spiritual spring is covered with a dragon trapped array, the land of the deep mountains is a demon soul killing array, and the land of the demon yuan is a bloody cloud fierce array.

There are spiritual veins hidden in the Drum Mountain, and it is the most ideal choice to build a dragon trap array, so Gu Feichen wants to build this 'Eight Desolations and Six Arrays'.

This formation is to use the abundant aura here, in the mountains to summon the distraction of the eight desolate dragon gods, the more abundant the aura, the longer the dragon god lurks in the mountains, the greater the power of this array!

On the basis of this array, a series of phantom arrays, killing arrays, and trapped formations are set up, so that the bases of several large arrays crisscross each other, and a complete protection system can be formed.

The reason why the chain array is set is because the Eight Desolation Divine Dragon has the characteristics of Liuhe, the so-called Liuhe is simply able to swim in all spiritual domains, and the spiritual array is precisely a kind of spiritual domain.

In other words, this giant dragon is able to swim, attack, and defend within the entire large array system, achieving 'switching large arrays without interference'. It can seamlessly connect all formations, can open and close all formations at will, the door of life and death is impermanent, and the array eye is difficult to be destroyed.

…………

The medicine garden is actually built in a small mountain range more than 20 miles long on the Drum Mountain, and there are two small peaks next to the secret room left by the grandfather, one is about two or three hundred zhang high, and the other is only more than 100 zhang.

Gu Changsheng surveyed the terrain in the air and decided to build the cave mansion on that higher peak.

But in order to hide people's eyes, he plans to make a maze array.

He flew into the middle of the stubby peak, found a very secret place in the deepest part of a cavern, and cut through the boulder with a scythe.

Half a day later, an underground passage began to take shape. This passage, which is two or three zhang in diameter, leads to the bottom of the mountain.

Gu Changsheng arranged a fake cave at the bottom of the peak, and at the entrance of the cave, another secret passage was opened to lead directly to the belly of the higher peak.

Subsequently, Gu Changsheng opened up another new cave mansion in the interior of the higher mountain peak according to the style of his cave mansion in the immortal realm.

There is no new entrance to this cave, and it is completely semi-enclosed except for the passage.

This is the place where Gu Changsheng really cultivates, alchemy, refining, and medicine gardens, so that there are two caves with one true and one false, and it is much safer.

After opening up the cave mansion, Gu Changsheng began to arrange the "Eight Desolations and Six Formations", and the range of this formation after opening was just enough to completely cover the two peaks and his grandfather's secret room.

It also happened to be nested in the large array that came to the Gu family's medicine garden, making it difficult for ordinary cultivators to find out that there was such a powerful large array here.

After completing all the work, Gu Changsheng flew between the two mountain peaks, hovered in the air for a while, and then began to continue to put on the three-layer chain array.

On the top layer, there were more than a dozen trapped formations and maze formations, and Gu Changsheng put all the excess low-level spirit runes on his body here.

And the core large array of the middle and lower layers, which contained more than a dozen killing arrays and trapped formations, Gu Changsheng made a bloody investment here, used many magic weapons, and even used two captured magic weapons.

Nine flying swords, those two demon souls, and a bunch of magic weapons captured during this time......

In this way, except for the hard attack of the cultivators of the Transformation Period, the Gu Family Medicine Garden is basically foolproof!

…………

"Squeak!"

The door of the tiled house was pushed open a crack, and a cute little fox rushed in.

"Immortal Venerable! I want to soak in the spiritual spring...... Yo, isn't it? Oh! This guy must have secretly gone to the secret cave! I'm just going to stay there and forget it! ”

Hong Aya stomped her feet, cursed in a low voice, hurriedly turned around and jumped out of the tile house, and immediately ran towards the Gu family's most secret room.

But as soon as she entered the low mountain peak next to her, her figure suddenly stopped, tilted her head to stare at the dense and deep forest in front of her, feeling the aura flowing slowly in it, and her forehead was instantly full of black lines.

She thought of the embarrassing experience of being trapped in those formations in the past half month......

If she hadn't known that there was an unformed dragon hidden in it, she would definitely be scared to death by this thing, and there were interlocking traps and mazes in it......

"Oh no, I forgot how to get out again! This way? Doesn't seem right, or is it this way? Oh! The formation here is simply annoying! Immortal Venerable, hurry up and save me! Oh my god, there are such powerful demon spirits here? ”

Seeing that the little fox was about to be eaten by the demon spirit, a breeze suddenly blew in the forest, and the trees shook slightly, and the flow of spiritual energy in it became much lighter.

Gu Changsheng's voice floated in the wind: "The formation has been unlocked, you can come in by yourself, don't come in if you run around in the future!" ”

The little fox blinked with teary eyes, cautiously leaned forward for more than ten feet, and after finding that he was still safe, he flew straight to the entrance of the cave in a rage.

After going around and around, he finally returned to the elegantly arranged secret cave, from which wisps of spiritual energy floated out, and the spiritual energy was very abundant everywhere in the secret room.

The little fox finally soaked in the spiritual spring, and sighed in his heart: Cultivating here is really ...... It's perfect!
