Qingfeng saw that the mountain guard formation had been repaired, so he happily jumped into the cliff and ran back to the cave, but he forgot about Ah Nu.

Ah Nu did not have the mark of passage to guard the mountain formation, so he was locked out of the formation at this time, and he couldn't help but smile bitterly in his heart.

He tried, and there was really no way to break this stone formation except for stone lentils. He didn't expect that this small stone talisman could be used to create such a powerful magic circle.

He suddenly thought that Qingfeng had said that the Book of Heaven could not only deduce the laws, but also crack the laws, so could the Book of Heaven crack this mountain guarding array?

Thinking of this, Ah Nu immediately began to try.

Since the six senses can't penetrate this circle, let's try the soul flow.

Ah Nu gathered his soul and channeled a trace of soul qi into the cliff. Although the soul flow can penetrate the mountain cliff, there is no way to send back information, what should I do?

Suddenly, a flash of inspiration moved in Ah Nu's mind, and the soul flow could transmit the six senses, so could it transmit the golden light on the Chaos Heavenly Book?

Ah Nu mobilized the soul air flow to touch the golden light on the Heavenly Book, and the golden light was easily integrated into the soul air flow, and Ah Nu also transmitted a trace of the six senses into the soul air flow, and at this time, the soul air flow loaded with the golden light of the Heavenly Book and sympathy began to enter the mountain cliff.

As soon as Jin Mang entered the mountain cliff with the soul airflow, the mountain cliff suddenly became blurred, and countless runes were swallowed by Jin Mang, and the image was transferred back to his mind through the six senses. In Ah Nu's mind, a rune array diagram soon appeared, and it was the five small formations that he had seen before that were operating.

However, as more and more runes in the mountain guarding array were swallowed by the Heavenly Book Golden Mang, the operation of the five small formations in his mind began to become sluggish. At this time, Ah Nu raised his eyes and saw that the cliff had become blurred, and a boulder beside him was also blurred, and the stone rune array disk was floating in this boulder.

The corners of Ah Nu's mouth rose, at this time, if he attacked that stone rune, he would definitely be able to break the formation. However, he didn't do this, he just used his spiritual power to protect his body, and he passed through the cliff with a single dive.

After this attempt, Ah Nu became interested in this rune stone formation technique, so he picked up a few pebbles, carried them in his arms, and happily returned to the cave.

Back in the stone room, Nu took out a pebble and played with it in his hand.

After thinking about it, he took out a blank rune stone of the abyss from the Demon Marshal Badge.

He held the two stones in his hand and felt them with his six senses.

The pebble is very ordinary, and its ability to carry and absorb spiritual power is really limited, and it is obviously not a good material for making an array disk, but compared with the runes of the abyss, it can withstand both light and dark spiritual power at the same time.

The rune stone of the abyss is made of a special spirit ore, and its ability to carry and absorb spiritual power is very good, however, it can only withstand the spiritual power of the dark attribute.

Nu put the two stones down, and already had an idea in his heart.

He first drew a dark realm barrier on the ground, activated it, and then cracked it with the Book of Heaven, recorded its formation diagram in his mind, and then drew runes on the blank rune stone with reference to the array diagram in his mind.

Several hours passed, and after carving several blank runes, Nu finally carved the array runes of the Dark Realm Enchantment onto a single runestone.

The rune stone of the Dark Realm was finished, and the entire rune stone emitted a faint black light.

Nu played with the rune stone of the Dark Realm in his hand for a while, and finally transferred the spiritual power into it.

Rumble...... The rune stone was activated, forming a dark realm enchantment of nearly a thousand feet around Nu.

Ah Nu's mind turned, he got up and jumped out of the stone chamber, and ran out of the cave, and the dark realm enchantment actually moved with him.

Ah Nu couldn't help but look up to the sky and roar. With this Dark Realm Runestone, he no longer has to crawl on the ground and spend time carving the Dark Realm Barrier, and he can carry the Dark Realm Barrier around his body, which is simply wonderful.

Nu returns to the stone chamber and finds Qingfeng looking at him with a look of astonishment.

Ah Nu said embarrassedly: "I accidentally tried a formation just now, did it affect you?"

Qingfeng rubbed his nose and said, "Sir, what kind of formation are you, can you teach me?"

Ah Nu scratched his head and said, "You can see if you can activate this with spiritual power." Nu handed the Dark Realm Rune Stone to Qingfeng.

When Qingfeng saw this rune stone, his eyes opened like copper bells, and it took him a long time to come back to his senses, and he hurriedly caught it and transmitted the spiritual power into it.

However, his spiritual power could not be transmitted into the rune stone at all, and his spiritual power was obviously a light attribute.

Qingfeng knew that he couldn't use this magic circle, and his face was full of loss.

Ah Nu said: "Qingfeng, don't be discouraged, I'm just just starting to learn to make stone runes, so there is no way to make high-level stone runes, wait for me to study it carefully, I will definitely help you make a few high-level stone runes." ”

When Qingfeng heard this, he immediately became happy and said, "Sir, I have a copy of the rune array atlas left by the Venerable Master here, do you want to study it for reference." ”

Ah Nu was overjoyed and said, "Great, I need it." ”

A few days later, Nu was playing with several stone talismans in the stone room, his face full of accomplishment.

After a careful study of the talisman array, Ah Nu carefully made five stone talismans, namely: Dayan Liangyi Concealment Array, Tiangan Five Elements Defense Array, Four Elephants and Seven Stars Strangulation Array, Liujia Nayin Group Attack Array, and Nine Palace Bagua Phantom Killing Array.

Among them, the Heavenly Stem Five Elements Defense Array is the mountain guarding array of this Xuanwei Zi Cave Mansion, this array can naturally absorb the power of the five elements of heaven and earth, transform it into endless energy, and defend against any immortal and spiritual attacks of light and dark attributes.

The Great Yan Liangyi Hidden Array, this array takes the number of the Great Yan fifty, and it uses forty to have nine ways, first yang and then yin, with static braking, concealing all the fairy breath, avoiding the exploration of the six senses, shadowless, formless, silent.

Four Elephants and Seven Stars Strangling Array, this array can summon the ancient immortals Qinglong, White Tiger, Vermilion Bird, and Xuanwu Four Elephants, and each elephant has its own seven stars, gathering the power of twenty-eight stars, strangling all immortals, blocking the space and having nothing to hide.

Rokko Nayin group attack array, this array summons sixty kinds of fairy sounds to carry out over-range attacks, which can cover thousands of miles.

Nine Palace Bagua Phantom Killing Array, this array uses the number of nine palaces and the variables of gossip to restrain each other, transform thousands of worlds, and can also erase all immortals in the illusion world.

With these five stone talismans, Ah Nu's heart is much more stable, and when they get together with Yu'er, they may be able to solve the problem of the displacement of the people of Nalan.

Ah Nu was thinking about his thoughts, but Qingfeng had already arrived outside the door and called softly: "Sir!"

Ah Nu came back to his senses, hurriedly beckoned Qingfeng into the door, and asked, "Qingfeng, is there something wrong?"
