Some broken worlds could be identified from the outside. If a sentient lifeform saw them and came out alive, they would mark the broken world to confirm the danger level. The information about these broken worlds was kept in the Earth of Mind Realm and recorded in a book — Forbidden.
That book only had one word — Forbidden. It was called the Book of Forbidden. The Book of Forbidden recorded the dangerous broken worlds that the sentient lifeforms had confirmed over countless years. There were more than a hundred of them. Most of these broken worlds couldn't be determined as the danger level couldn't be determined because no one from the consciousness universe was willing to test them. Many of the broken worlds were recorded by hunting down cultivators from the spiritualized universe and using those cultivators as a reference to determine the danger level.
Furthermore, the broken worlds would float away and weren't easy to find. However, some broken worlds were still seen clearly.
The broken world mentioned by Dancing Butterfly Butterfly Horizon happened to be one of the broken worlds that were seen clearly. There was a creature in that broken world that held a bamboo blade and had the strength to threaten the 13 Heavenly Phenomenon Realm. It was one of the most dangerous broken worlds and was called the Bamboo Blade Broken World. In Wu Wei's memories, there were more than five broken worlds in the Book of Forbidden that were comparable to the Bamboo Blade Broken World. There were also some broken worlds that were more dangerous than the Bamboo Blade Broken World. However, other than the 13 Heavenly Phenomenon Realm, no lifeform dared to test them. Therefore, no one knew how dangerous they were.
Dancing Butterfly Butterfly Horizon was already very lucky to come out of the Bamboo Blade Broken World.
That creature with the bamboo blade made Wu Wei apprehensive. Of course, that was a long time ago. Back then, Wu Wei had just become a 13 Heavenly Phenomenon Realm cultivator and didn't have his current strength. He hadn't learned the Sword of Heaven yet. However, even the current Wu Wei wouldn't want to provoke the Bamboo Blade Broken World. There was no need.
The spiritualized universe should also know about the dangers of the broken worlds. However, human cultivators didn't have a high chance of survival after entering the dangerous broken worlds. Moreover, after a batch of cultivators went there, they would return after a period of time. Many people would never go there a second time. As a result, they didn't create anything like a Book of Forbidden. They could only warn people not to enter the broken worlds.
However, this warning was pale and powerless in the face of a threat to the sentient lifeforms.
All sentient lifeforms had an unspoken rule that came from their instincts. Under the premise that they could eliminate the enemies from the spiritualized universe, they would try their best to use them to test the dangers of the broken worlds. Compared to the spiritualized universe cultivators who were numb and ignorant of the broken worlds, they wouldn't be willing to test any broken world unless it was truly confirmed that the broken world wasn't a threat.
The consciousness universe was the home of the sentient beings. They were more willing to recognize the broken worlds and make use of them.
Lu Yin finally understood why the spiritualized universe was so much more powerful than the consciousness universe, but it was still difficult to completely deal with the consciousness lifeforms. The broken world was a major obstacle, and there was also the direction of the Ninth Heaven Universe behind it. Whether or not the consciousness lifeforms could be restarted was far from something the spiritualized universe could decide. Even Master Grass, who was in the Eternal Realm, could not decide.
And after realizing this, the Tian Yuan Universe was in even greater danger. This was because the Tian Yuan Universe did not have a destroyed world.
In the distance, everyone was very curious about the broken world. They kept asking the spiritualized universe's cultivators about it. Not only Dancing Butterfly Skyline, but Old Tao was also one of the people being asked. Yuanqi, Zhan Yan, and the others, especially Ancestor Xi, Dancing Butterfly Skyline also wanted to ask her some things.
Lu Yin clapped his hands to attract everyone's attention, "Ancestor, share all the information you know about the broken world. Old Tao and the rest, tell us everything you know to prevent Wu Jiang from being in danger."
Old Tao hurriedly expressed his stance. "Don't worry, Master. This lowly one will definitely tell you everything from the first time I entered the consciousness universe to the last time I left. I'll let everyone experience it personally, right, Ancestor?"
Ancestor Xi fell silent.
Starting from Old Tao, everyone began to talk about everything they knew about the consciousness universe. Old Tao had experienced a lot in the consciousness universe, so he spoke in exultation and was as detailed as possible. At first, everyone was interested, but they gradually realized that this fellow was just trying to make his presence known. He wanted to show off in front of Lu Yin, which was why he was chased away.
The Ancestor Xi was the one who looked forward to it the most. Only then would her words be valuable.
Dancing Butterfly Skyline was also very curious. A consciousness lifeform was equivalent to an Astral Phenomenon, which was not weak. She could be considered a second-grade consciousness lifeform, so what would her knowledge of the consciousness universe be like?
Since ancient times, many consciousness lifeforms had surrendered to the spiritualized universe, but they had never had the chance to interact with them.
Under everyone's gazes, especially Lu Yin's, Ancestor Xi muttered to herself for a moment before slowly explaining what she knew about the consciousness universe.
Lu Yin's gaze was calm as he listened.
"As for the destroyed worlds, all consciousness lifeforms revere them. They have existed for much longer than us, and all consciousness lifeforms believe that the destroyed worlds form the consciousness universe. If we lose the destroyed worlds, the consciousness universe will be reduced to the same level as the spiritualized universe."
"That's right, you didn't hear wrong. To the consciousness lifeforms, a universe without a destroyed world is ordinary, even if the spiritualized universe is stronger than the consciousness universe."
"The consciousness universe's thirteen celestial phenomena are known as the Realm of Earth. In that realm, there is a book called the Forbidden Book. This book records the consciousness lifeforms' knowledge of the destroyed worlds, including some of the destroyed worlds. Among them …"
The Book of Forbidden was something that Dancing Butterfly Skyline and the others did not know about. Yuanqi was also astonished, as he did not know about it either.
Lu Yin frowned. The spiritualized universe had been fighting in the consciousness universe for so many years, but they did not know about the Book of Forbidden?
Many lifeforms in the consciousness universe had surrendered to the spiritualized universe, but there were no lifeforms that could exchange information for equivalent value?
Impossible.
Either that, or only those who had reached the Astral Phenomenon realm had the qualifications to know about the Book of Forbidden, and lifeforms at that level did not necessarily need to exchange the Book of Forbidden for value, as they themselves were very valuable. Or, the Book of Forbidden had existed for a shorter period of time than Yuanqi and the others.
That was not impossible.
Yuanqi was an ancient lifeform that had existed since the Tianyuan Era. Although the spiritualized universe had a longer history than the Tianyuan Universe, it was not that exaggerated and had only developed for a few more eras. The consciousness universe's history might not have surpassed the spiritualized universe's. When Yuanqi was in the spiritualized universe, the Book of Forbidden might not have been formed yet.
Then the question was, how did Ancestor Xi know about it?
She had gone to the Tianyuan Universe at around the same time as Yuanqi.
"Based on what you know, how many broken worlds are recorded in the Tome of Taboo?" Lu Yin interrupted the Ancestor.
Ancestor Xi replied, "More than ten."
Lu Yin's eyes flashed. More than ten?
That meant that the Book of Forbidden had only just begun when Ancestor Xi knew about it, so it was understandable that Yuanqi did not know about it.
Ancestor Xi had gone to the Tianyuan Universe at around the same time as Yuanqi, and the Book of Forbidden was a consciousness lifeform, so she naturally knew about it.
Lu Yin had asked Ancestor Xi to speak because he wanted to see if she would talk about the Book of Forbidden.
If she didn't, it might be because she didn't know or because she wanted to hide it. There was no pressure at all because it was impossible for her to know that Lu Yin knew about the Book of Forbidden. If she spoke about it, would it be a show of sincerity?
Ancestor Xi was able to go from the consciousness universe to the spiritualized universe and from there to the Tianyuan Universe. She was different from normal consciousness lifeforms.
The instinct of consciousness lifeforms was to survive, but Bai Wushen had feelings for him because of Yan 'er. Consciousness lifeforms could change.
They might not be pure lifeforms.
Lu Yin turned around and left.
Ancestor Xi took a look and continued.
"Yi Shang, do you know about the Book of Forbidden?" Lu Yin asked. Yi Shang stood behind him.
Yi Shang didn't talk to Yi Xia in Torch City as it was too sensitive. He was afraid that Yu Sang Tian would slap Yi Xia to death.
Fear of the unknown was just fear. In the past, they had used a springboard to conquer the Tianyuan Universe.
Yi Shang said, "I know, a consciousness lifeform recorded a book about a dangerous destroyed world, Yi Earth Realm, but I have never seen it before."
"You didn't find out about the book from the consciousness lifeform?"
"I can't do it. If I could, I wouldn't have to wait until Ye Meng betrayed me before I found the Yi Earth Realm."
Lu Yin thought about it and agreed. He knew why he couldn't do it: it was because of Old Head.
Old Chief was the leader of the 13 Celestial Phenomenon in the consciousness universe, and was also the oldest consciousness lifeform. He had planted the Locking Autumn spell in every powerful consciousness lifeform, locking their consciousness so that the consciousness lifeform would not be able to speak of certain things, and outsiders would not be able to investigate these memories.
Lu Yin had sensed Locking Autumn when he entered Hua Manyi's body, but it couldn't stop him. As long as Hua Manyi had these memories, Lu Yin would be able to see them. Thus, he had seen Yi Tian Que's situation through Hua Manyi.
It was impossible for Yu Sang Tian to understand Yi Tian Que through Hua Manyi, as even Hua Manyi couldn't say anything.
And because Wuwei had surrendered too early, he hadn't been Locking Autumn.
Hua Manyi had once guessed that Yu Sang Tian's main goal in attacking the Yi Earth Realm was Yi Tian Que. He guessed that Wuwei had told Yu Sang Tian about Yi Tian Que.
In reality, Wuwei hadn't told Yu Sang Tian about this, and Yu Sang Tian hadn't asked.
No one had asked Yu Sang Tian whether he knew about Yi Tian Que.
To outsiders, everyone believed that Yu Sang Tian wanted to attack the Yi Earth Realm and destroy the 13 Celestial Phenomenon so that he could restart the consciousness universe and step into eternal life. No one knew if that was the truth.
From Hua Manyi's memories, Lu Yin purposely read Old Head's memories.
This leader of the 13 Celestial Phenomenon rarely showed himself, and Hua Manyi didn't know how strong he was.
Using the Yi Earth Realm to plot against Yu Sang Tian was Old Head's plan, and he seemed to be very confident.
Wu Wei also had memories of Old Head, but they were also very few.
"Is there anything similar to a tome in the spiritualized universe?" Lu Yin asked.
Yi Shang replied, "There are some that have been passed down by word of mouth, but it's just a few broken worlds that are obviously dangerous. However, these broken worlds haven't been seen for a long time, so they might have disappeared. Broken worlds aren't fixed forever. Some of them may look like this at one moment, but the next moment, they might change. It's impossible to see through them completely. There must be a batch of broken worlds that have expired in the tome of consciousness lifeforms."
Lu Yin felt that something was strange. Expired? Although it sounded strange, it made sense.
Broken worlds could expire as well.
Yi Shang continued, "In the past, the spiritualized universe also wanted to create something similar to a tome, especially after learning of its existence. However, the cost of creating something like this is too great, and there's no point in just exchanging information. The truly dangerous broken worlds need to be constantly probed, and the broken worlds that can be exchanging information aren't that dangerous.
"If you want to probe, you'll have to pay with human lives, and the lives of experts at that. The price we have to pay to explore a broken world is much higher than the cost of the consciousness lifeforms, but that's still acceptable.
"Compared to the losses caused by broken worlds, Yu Sang Tian and Sang Tian have discussed it, and we're willing to pay the price of losing a generation of experts to explore a broken world.
"However, after discovering that broken worlds can change and expire, the price is completely different. There's no need to explore them anymore."
