"What's so great about this mountain guarding formation, isn't it just that the stone lentils can be broken with the power of a sword?" Thinking of this, Ah Nu was noncommittal in his heart, touched his nose and followed the little boy, and stopped talking.

There is a karst cave in the waterfall water curtain, which is dozens of zhang high, and the surrounding area is full of dissolved stones, which is extremely cool. The whole big hole is like an ancient tree with intertwined roots, spreading out, there are holes in the hole, and there are deep dark rivers interspersed. There is an oil lamp every few zhang between the cave walls, and the light is projected on the crystal clear karst stone around it, which illuminates the whole karst cave brilliantly.

After walking dozens of steps, turn into the belly of the mountain, and at this time a pool of inner lake appears in front of you, and there is a light boat parked on the lake. The boy invited Nu to jump on the light boat, but there was no pole, and the light boat actually moved on its own and drove automatically along the lake into the depths of the mountain. Bats overhead, whitebait in the water, and the tinkling of spring water all around.

A moment later, a white curtain of light suddenly appeared in front of him, and the light boat slowly sailed into it.

Ah Nu's eyes suddenly brightened, but he entered a wider stone cave, the stone cave was full of cigarette smoke, candlelight was bright, and all sides were smooth as mirrors, and the wall was carved with dense lines, pictures, and runes.

The river had come to an end, and Nu had to go up several stone steps with the boy from the boat, and saw a stone room in front of him, and a short old man with white eyebrows and white beard stood in front of the door of the stone room with a bamboo cane.

The boy saluted the old man, and without saying much, he walked into the stone chamber by himself.

Ah Nu grabbed his head and stepped forward, also saluted the old man, and said, "Old man, disturb me." ”

The old man smiled and replied, "Fellow Daoists don't have to be restrained, please come with me." ”

"What does this mean?" Ah Nu didn't understand, and followed the old man into the stone room.

There is nothing in the stone chamber except a stone table and two futons. The old man sat down on one of the futons, and the boy stepped forward to make two bowls of fragrant tea on the stone table, and placed a plate of vermilion fruits.

Before Ah Nu could sit down, the dream fox in his arms had already poked his head out, licking his lips and staring at Zhu Guo on the stone table.

The old man laughed and said, "Let her down, this hundred immortal fruits will be beneficial to her, so let her eat a few." ”

Menghu's eyes lit up, and with a twist of his body, he jumped out of Ah Nu's arms and landed steadily on the stone table.

Gollum!

After the three Zhu Guo went down, Menghu burped and actually climbed on the stone table and fell asleep.

Ah Nu sat down, took the dream fox back into his arms, and said with a sneering face: "My spirit fox is greedy, which makes the old man laugh." ”

The old man touched his white beard and said, "Okay, this spirit fox will have unlimited achievements in the future after this ordeal." ”

Ah Nu's heart moved, and he asked, "How do you know about her ordeal?"

The old man smiled: "I have some research on the technique of luck deduction. ”

Ah Nu muttered, "The technique of luck deduction?"

The old man smiled but said nothing.

Ah Nu thought for a while and asked, "Old man, I heard that the little brother said just now that you have been waiting for me here, I don't know what you are waiting for me?"

The old man nodded and said, "Before I talk about this, I want to ask you some questions. ”

Ah Nu said, "Please speak." ”

The old man said: "Daoist friends must have been to some interfaces, but I don't know how much you know about the mortal realm and the worlds?"

Ah Nu was stunned when he heard this, and replied: "I only know that the Realms and the Mortal Realm belonged to the same Chaos World in ancient times, and as for the rest, it seems that the aura of the living beings in the Mortal Realm is much stronger than that of the Mortal Realm, and the living beings are also much stronger. ”

The old man said, "Well, you're only half right. ”

Ah Nu was very curious, and hurriedly replied: "Please also ask the old man for advice." ”

The old man said: "The worlds and the mortal world belonged to the same chaotic world in ancient times, this is true. However, since the collapse of the chaotic world, only the mortal realm can still have complete interface rules, while the other interfaces have become remnants, and the interface rules are incomplete. ”

Ah was puzzled and asked, "But why, the creatures in the other interfaces I see are much more powerful than the mortal realm?"

The old man smiled slightly and said, "What you see is only the surface, living beings are living beings, there are living beings, although the other interfaces are full of spiritual energy, but the vitality is very lacking." ”

Ah Nu didn't understand, and asked again: "What is vitality? In those interfaces I saw, the living beings are very powerful, and some have even lived for thousands of years or tens of thousands of years, how can this be said to be a lack of vitality?"

The old man said: "When I say vitality, I mean vitality, which is the qi that binds life to the source. That's right, you see that most of the creatures in other interfaces are stronger than the creatures of the mortal realm, and that's because they are full of aura, and auraism can make life strong, but it can't create new life. ”

Ah Nu was confused, and couldn't help asking: "However, in other interfaces, I also see the birth of living beings and the reproduction of life." ”

The old man said: "That's because these interfaces have established a connection channel with the mortal realm, they need to rely on the mortal realm to transport vitality, and they need to rely on the mortal realm to repair their broken interface rules. ”

Ah Nu called out in disbelief: "Huh!?"

The old man smiled and looked at Nu.

Ah Nu thought for a long time before asking, "What are the complete interface rules?"

The old man raised his head and said: "Alternating light and dark, yin and yang are coordinated, reincarnation is reborn, and chaos is eternal!"

Ah Nu shook his head and said, "I don't understand, please tell the old man more details." ”

The old man said: "The alternation of light and dark is the seed of life, the balance of yin and yang is the root of life, reincarnation is the leaf of life, and chaos and eternity are the fruit of life." ”

A flash of inspiration flashed in Ah Nu's mind, as if a golden avenue had been opened, he stopped talking, closed his eyes and began to silently comprehend these words.

The old man nodded, as if he was very satisfied with Ah Nu, and he slowly got up and walked out of the stone room......

At this time, Ah Nu's mind was clear, and the transparent spirit seed rotated slightly, and the transparent spiritual energy suddenly dispersed under the rotation of the spirit seed, one black and one white, and the two spiritual energy currents were entangled and swam to the heart, and from the heart to the lower abdomen. The gray Yuan Force Qi flow in the lower abdomen suddenly spun up, inhaling two black and white spiritual powers, and after a while, he spit out a gray Yuan Force Qi flow and swam towards the heart. At this time, the spirit embryo on the spirit seed suddenly flashed with colorful light, and spit out a seven-colored air flow, and the colorful air flow also swam to the heart, merging with the gray Yuan Force air flow......

For a while, Ah Nu's heart emitted a colorful light, and his blood also turned into a colorful color, and the colorful blood spread to all parts of his body, and colorful lights emanated from Ah Nu's body......

Ah Nu's spirit seed was originally formed by alternating light and dark, and his encounter with Ah Yu experienced the reality of yin and yang coordination, at this time, although his spirit seed was still in the spirit embryo stage, this spirit embryo unconsciously gave birth to a radicle......

After a few hours, the colorful light converged, and Nu finally opened his eyes. He stretched out his palm and stared blankly for a moment, a thoughtful look on his face.
