In essence, the universe itself is composed of a potential material energy, countless small energy molecules, constitute countless small energy molecules, and then form larger energy molecules, these energy molecules are constantly moving all the time, colliding, swapping, until destruction, and finally reborn, the movement of large and small energy molecules, and finally constitute the cyclic theorem of the cosmic energy group, before the emergence of larger energy groups, this universe will always be endless, Just like a game of Go full of black and white chess pieces, four black pieces eat one white piece, but the evolution of this substance will never end, which is the original theorem of yin and yang transformation.

Spirit, is the world's most superficial energy substance, but also the most mysterious legend, the spirit of the heavens, people in pursuit of the true face of the heavens, pay a lot, but so far, no one can really explain what the real heavens are.

If you have to select a few epoch-making characters on top of the evolution of the spirit, then Luo Yu Wei will become the latest one, just in the imperial capital Chihong, he successfully cracked the phantom light wall of time and space, this is Hong Jun Di La created the unbreakable barrier of the Three Realms, the first person who can break the ban with the power above the original spirit, and the legendary "Tower of Demons" summoned by Luo Yu Wei will become the largest source of energy in history, and the Tower of Demons is directly evolved from the Demon Pool, And it has become a center similar to "energy harvesting", rising from the ground above Chihong City, which can absorb all the yin spirits to complete the summoning of the "Gate of Demons".

From a long time ago, there has been a saying on the continent: when the door is opened, everything will be dead, and then reborn, and the world will be reborn.

This rumor came from the tasty dossier of the Cult that had been abolished, and as early as a thousand years ago, the Imperial Priests tore this volume from the Cult, some said that the contents of that volume were burned by Emperor Xuan, while others said that it was used by evil sorcerers, and evil black magic and necromancy were born.

Sure enough, within a quarter of an hour, Dongfang Ziyan, who was walking in front, followed the light, and sure enough, he saw a stone door, the edge of the stone door and the tunnel mouth were tightly sealed, there was no gap, Dongfang Ziyan handed over the hand lamp to Rhine behind him, and asked him to help illuminate it, he walked to the stone door, and a chessboard was placed on the door, and there were half of the chess pieces on it, he gently touched the stone door with his hand, and knocked lightly with his fingers, making a muffled sound, and then he put his ear on the door and listened for a while, and said decisively, "There is a strict mechanical structure in this door, It should be a mechanical defense system similar to a black box cannon, and forcibly destroying it will inevitably cause an explosion, and if it explodes in this tunnel, it will not only bury us alive, but also destroy the only way to the underground palace. ”

Saint Huang stood behind and nodded thoughtfully, and the mechanical arm touched the top of his head, "That chessboard is not easy to unravel, and it took me a full day and a night to unlock it last time I unlocked it." ”

"As long as it's a mechanism, there must be a way to unlock it, look at me." Dongfang Ziyan said confidently, but he became a little worried again, turned around and said, "Uncle, Shenghuang, this is a forbidden place, wouldn't it be bad for us to break in like this, that's a heavenly opportunity!" ”

"As a neutral person, first of all, we must not believe in the saying that 'if you leak the heavens to confuse people, you will be punished by heaven'." Rhine said earnestly.

"That's what the teacher said, and I haven't seen the teacher in a long time." Dongfang Ziyan silently lowered his head.

"Sereant Deesch Dragon, as the only owner of the Holy Eye in the world, should have stood with us, but he is too rigid for his mission to be." Shenghuang let out a long sigh from behind, and then walked over slowly, and the cold mechanical arm slapped Ziyan's shoulder, "It's better for me to come, don't embarrass you first." ”

"Thank you." Dongfang Ziyan looked up at the terrifying face of the Holy Phoenix and said.

The Holy Phoenix is worthy of being the emperor of the mechanics, the spirit emperor of the Jialuo Ling clan, under his precise operation, in less than a quarter of an hour, the chessboard lock on the stone door was opened, and the three of them did not hesitate and immediately entered the door.

After the stone door was opened, there was a series of stairs extending downward, as wide as the long staircase of the imperial capital Changle Palace, and it was still pitch black inside, so Dongfang Ziyan still held up the lamp to illuminate. There was still no smell of old and moldy inside, but there was a faint fragrance, but Dongfang Ziyan knew all kinds of herbal medicines, so he recognized that it was not a medicinal fragrance such as incense, nor was it like the fragrance of burning incense, but like the faint fragrance of wood such as sandalwood or agarwood.

Finally, they walked down the stairs, in front of them was a steady road, on both sides were walls more than six meters high, just a few steps, Dongfang Ziyan saw murals and stone carvings on the wall, and some grottoes, that is, the statues of people carved on the wall.

Those humanoid statues are carved directly on the wall stone in the shape of real people, and through these humanoid sculptures, it can be seen that the clothing and hair decoration of the Li Nan people are not much different from those of the current people. There are murals between the statues and statues, and under the murals is a series of ancient incantations, among the three people, only Shenghuang and Dongfang Ziyan understand some ancient incantations, but they are only half a catty and eight taels, and they can only understand a little, with the murals above, all the contents are connected to see, which probably means that it describes all the previous lifestyles of the Li Nan people, as well as creation and invention, as well as the dialogue between the prophet and heaven and earth, although the description is true, but it can still be vaguely seen that there are a lot of fictional pictures, because heaven and earth will not speak.

Suddenly, Dongfang Ziyan suddenly felt the eyes of the stone statue glance at him when he passed by the humanoid statue, and couldn't help but exclaim, "What is that!" ”

Although Rhine and Shenghuang are both calm old rivers and lakes, in such a dark and secluded underground, hearing Ziyan shouting for no reason, of course they will be startled, only to hear Dongfang Ziyan shout, the two looked at the stone statue at the same time, but they didn't find anything unusual.

"What are you doing?!" Rhein thought he was being funny and slapped him on the head hard.

"I didn't scare anyone, that stone man's eyes moved just now!" Dongfang Ziyan covered his head that was hurt and pointed to the stone statue and said.

Saint Huang listened to Ziyan's words, stretched out his mechanical arm, only to hear the sound of mechanical rotation, his arm stretched out by nearly a meter, reaching a length long enough to reach the head of the stone statue, and then touched the stone man's eyes, "You read it wrong, how can these stone heads have life, even if they are monsters made with witchcraft or earth magic, they can't appear here, if there really is, I found out when I came last time." ”

"Maybe, maybe it's my delusion." Dongfang Ziyan wiped the cold sweat on his head, but he really didn't lie, he thought to himself that maybe this claustrophobic underground would really make people panic.

After knowing that it was okay, the three of them continued to walk forward, but this road seemed to have no end, like a bottomless black hole.

I don't know how long they walked, they were silent, and they didn't find anything related to the Black Stone Demon Clan, and the maze that the Holy Phoenix said before was extensive, and there were only stone statues and murals everywhere they went, as well as text carvings. Shenghuang was the first person to sense that something was wrong, she said that she might be stuck in a cyclic labyrinth like Qimen Dunjia, and the best way to crack this kind of magic is to stand still, waiting for the mechanism to run over, and the exit will automatically appear, so they sit on the ground, just enough to pay attention for a while.

"It's a lot like the volcanic dungeon in the North Pole." Dongfang Ziyan rubbed the blade of the long knife with a cotton ball.

"Volcano Underground Palace, you're talking about the place where the Red Emperor's charm is sealed, the place guarded by the beast god Suzaku." Shenghuang said.

"Yes, it was there that I met my uncle, and I walked there under the guidance of Suzaku at that time, rescued my uncle from the enchantment, and got the Red Emperor Charm."

"Speaking of which, this kid is still my savior." Rhine patted Ziyan on the shoulder and said.

"But I didn't see the Red Emperor Charm in your hand, it was the second of the thirteen artifacts, and it was the weapon of the former Hongjun Empire's Xuanhuang Hongjun Long." The Holy Phoenix seemed to be a little incredulous, because he had only seen the ordinary slender blade in Ziyan's hand.

"The Red Emperor's Charm ...... The sword soul of the Red Emperor was taken away, and now it is like scrap metal," Dongfang Ziyan sighed, "The Red Emperor has accompanied me for a long time, but it was my fault to discard him that time." ”

"Wait, you never told me that the Red Emperor was taken away from the sword soul." Rhine seemed to have woken up and said to Ziyan.

"What's wrong, what do you think?" Dongfang Ziyan asked when he saw that Rhine was a little abnormal.

"There is a sword soul spirit crystal in the Red Emperor Charm, which can exclude everyone except the sword master, and the Iron Fist Zhou Haoran died like this back then, so it is normal for Xingtian to take out the sword soul, but why only as long as his sword soul, but throw away the artifact, it can be seen that there must be an unknown secret in it." Rhine said in a quick tone.

Before the words fell, Shenghuang and Dongfang Ziyan were a little shocked, Ziyan reacted quickly, and immediately said firmly, "Before, Cangyue contacted me when I was in the river basin, saying that there were several mysterious black-clothed people in the Tower of Babel, and I don't know why, they defeated the trial Du Aisen, and also took away the sword soul of the snow walking moment, and the snow walking moment is also one of the artifacts, is there any secret in the sword soul of the artifact?" ”

As he spoke, Rhine took out his Huangquan Tiandu and stared at it with the light in Dongfang Ziyan's hand, but found nothing.

Shenghuang pondered for a long time, and said slowly, "In the ancient Hongmeng era, the Rinan people and other human branches were able to penetrate the heavenly machine on the human race, and got a lot of experience to talk about, and will record a large number of methods to control the original spirit of the universe, and, after continuous modification and accumulation by later generations, it has been formed in the era of chaos. Ten phases of freedom diagram', someone else said. As long as you can combine the oracle book and the ten phases of freedom diagram together and interpret it, you can have the ability to solve all the unsolved mysteries, and this is only a superficial conjecture, and its effect may be even deeper. Shenghuang paused, "But in the later part of the Chaos Era, in order to prevent the leakage of the Heavenly Machine, the Xuanhuang Emperor Hongjun Long of the former Hongjun Era, collected the Ten Phases of Freedom Diagram, and divided the Book of Heaven into thirteen parts, which were sealed into the spirit of the Ancient Giant Beast Eight Deception Gods and the Five Spirit Beasts, and later the Five Spirit Beasts became the Guardian Beast God of the Artifact, so they sealed the fragment of the Book of Heaven into the artifact Sword Soul, I think, what the Black Stone Demon Clan wanted was the fragment of the Book of Heaven. ”

"I was fortunate enough to read it in the Demon Realm Hidden Scripture Pavilion, and it was superficially recorded in it." Dongfang Ziyan sighed, "The teacher said that the Oracle Heavenly Book and the Ten Phases of Freedom Diagram caused the great chaos of the rise of alien races at that time, and various forces continued to wage wars in order to get these two things, resulting in the people's misery, and the grass did not grow where the war spread, so Emperor Hongjun was right to do that back then, I think if it were me, I would have destroyed the calligraphy and painting more directly." Dongfang Ziyan said.

Rhein listened quietly and dropped a cigarette.

"Do you know what happened after that?" Shenghuang raised his eyes and looked at Ziyan and Rhine, and said seriously, "I only mentioned a little bit in it. ”

"Let's talk about it." Dongfang Ziyan withdrew the long knife into the long scabbard at his waist.

Shenghuang sighed, "After the death of the former Hongjun Empire in Long, because of the contradictions between the human race and nobles caused civil strife, Hongjun Ling, who had already been established as the crown prince, was killed by his imperial brother and imprisoned, and the new emperor was imprisoned after Ling, and the famous 'Hongjun Pillar', Ling's henchmen, and the forty-six generals of the Xuanhuang Emperor were all executed, and the Nieling clan of the foreign family saw that the forty-six would die unexpectedly, and there was no one to defend in the imperial capital, so they took the opportunity to rebel, and at the same time, the Jialuo Ling clan, the Xiyue Demon Clan, the beast clan and the ancient dragon clan that had just given birth to the embryonic form arose, Threatened the border of the Terrans, when there were internal and external troubles, Nering Chexing captured the imperial capital in one fell swoop and established the Nieling Empire, after that, Nieling Chexing built a lot of construction on the land of the Terrans, and the Treasure House and the Scripture Pavilion of the Hongjun Empire were wantonly scavenged, and the Terrans were cleaned inside and out, and finally destroyed the tombs of the successive Xuanhuang, and also looted them on a large scale, and finally got the ten phases of freedom he dreamed of in the coffin of Hongjun Long who had just entered the ground. At the same time, the search was carried out according to the five spirit beasts and the legendary habitat of the eight deceitful gods, but after many years, nothing was found, which can be regarded as evil retribution, Hong Jun Ling, who was killed by the imperial brother, did not die in prison, but with the help of whom, escaped when the Nirling army broke through the city pass, and fled to the Wuya in the northeast, after years and months of recruitment, established a revolutionary army, and cooperated with my ancestors and other tribes, as well as the Black Stone Demon Clan, which had also just appeared at that time, to launch a multi-faceted simultaneous attack on the Nirling Empire, That is, the first rebellion of heaven and earth, the battle is really rare, the tribes and forces involved are the most ever, and finally Nirvana was defeated, but the ten phases of freedom were gone, only the legend of the fragment of the book of heaven remained, until now, it is just a legend. ”

After saying this in a hoarse voice, the Holy Phoenix began to cough violently, as if he had just finished recalling a sordid history.

"It seems that Luo Yu's ambition is not only to destroy the Terrans and the Faitus Protoss......" Rhine said thoughtfully.

Just as Rhine had just finished saying this, Dongfang Ziyan looked at the mural on the wall, and suddenly froze, staring at the mural, as if he was surprised that he couldn't say anything.

"What's wrong?" Seeing that Ziyan was a little abnormal, the Holy Phoenix asked.

"I understand...... Dongfang Ziyan pointed to the mural on the wall as if he had lost his soul, "It turns out that it already knew the end of all of us a thousand years ago......
