After bidding farewell to Azure Lotus Emperor, Lu Yin looked at the Startling Sparrow Terrace and the Blood Nine. There was no need to go there anymore. Their answers were the same as Azure Lotus Emperor's; they wouldn't stop just because of a few words.
Azure Lotus Emperor was right; they weren't doing this for themselves, but for the future of human civilization.
Lu Yin was overthinking things, but he also needed to understand the situation of the Eternal Realm so that he could prepare for future battles.
After returning to the Tian Yuan Universe, Lu Yin spent the next ten years calming his heart and becoming one with the universe. He felt the joys and sorrows of countless people, trying to push his state of mind to eternal life and pass the Bitter Adversity.
However, the Bitter Adversity wasn't that easy to pass. His Bitter Adversity was to let go, which was something he had figured out when he became one with the Tian Yuan Universe. Before that, when he saw the murals in Ye Hai and comprehended the karmic wall, he had already stepped into the Bitter Adversity.
Lu Yin believed that this was his Bitter Adversity, but he had communicated with many people over the years, and they all believed that they had found their own Bitter Adversity. But was it really their Bitter Adversity?
Lu Yin clearly believed that letting go was his Bitter Adversity. It was like seeing the light in the sky, but the more it was like this, the more likely it was fake. Otherwise, why couldn't so many powerhouses achieve eternal life?
Was he smarter than those people?
More thorough than those people?
No one was necessarily smarter than others.
Letting go wasn't giving up. The process of passing the Bitter Adversity was a process of letting go. This was Lu Yin's understanding of his Bitter Adversity, but he still didn't feel like he was close to the Eternal Realm.
He couldn't even see the complete Bitter Adversity.
Was letting go really his Bitter Adversity?
One day, Shang Tianzong asked for an audience.
"Limitless Empire's Shang Tianzong greets Master Lu."
Lu Yin sized up the person in front of him, "Long time no see, Emperor Shang."
Shang Tianzong was Limitless Empire's Emperor Shang. When Limitless Empire came into contact with the Genesis Space, the previous Emperor Shang died. Shang Tianzong was Lu Yin's successor, but Lu Yin had forgotten about him. After all, Limitless Empire's people didn't cultivate and only studied mechas.
It had been hundreds of years since he last saw Shang Tianzong. He didn't expect him to still be alive.
Shang Tianzong was terrified, "I'm no longer Emperor Shang."
"Oh?
Why are you looking for me? "
"This subordinate reports to Master Lu that the thirteenth ring energy is a success."
Lu Yin's eyes brightened, "Thirteenth Thirteenth Ring?"
Shang Tianzong smiled and said, "Yes, please accept it."
Lu Yin was delighted. "Alright, let's go take a look." He teleported away with Shang Tianzong.
Ring energy was the foundation of all energy in the Limitless Empire. Using the cycle as the source of power, every cycle would increase the power of the Limitless Empire.
The Limitless Empire specialized in manufacturing mechas. Ring energy was the energy of the mechas.
One ring could create a mecha that could fight against an Explorer, which was the equivalent of an Explorer. Two rings could be used against Hunters, three rings for Enlighters, four rings for Enlighters with power levels of 400,000, five rings for Emissaries, six rings for Emissaries, seven rings for Emissaries, and eight rings for Emissaries.
A mecha that reached the ninth ring could fight against a Half-Martial Ancestor, a tenth ring could fight against a Martial Ancestor, and an eleventh ring could fight against a Martial Ancestor. In the past, the most powerful mecha in the Limitless Empire was at the twelfth ring. There were only a few such mechas in the entire Limitless Empire, and each of them had a name.
Lu Yin still remembered the first time he had crossed swords with the Limitless Empire. Their mecha had stunned them, and the Limitless Empire had relied on their mecha to conquer one parallel universe after another.
However, with the Eternals' war and the appearance of foreign civilizations, the mecha's usefulness had dwindled. Even so, Lu Yin had never given up on them.
These mechas had also participated in the Limitless Empire's expedition into the spiritualized universe, and under certain circumstances, they were irreplaceable. What Lu Yin looked forward to the most was the research on the thirteenth ring.
Once the research was successful, the human civilization's power level would definitely soar.
The thirteenth ring could be used to create mechas that could fight against a Primordial realm expert.
What was the Primordial realm?
The Primordial realm was the beginning of the final three stages. Whether it was the Heaven's Origin Universe or the Ninefirmaments Universe, a Primordial realm expert was an expert, and no civilization would underestimate a Primordial realm expert. The Primordial realm would never be synonymous with quantity.
This was true even for the Insect Wave civilization.
However, if the research on the thirteenth ring was successful, then the Primordial realm's power level would be synonymous with quantity.
Why was the Technological Fishing civilization so terrifying?
It was because the weapons they created could reach the level of Eternal life forms, but they were not bound by karma. They could be used as long as they had the resources.
It was the same for the Limitless Empire's mechas. As long as the research was successful, they could be mass-produced.
In the past, the Limitless Empire only had a few twelfth-ring mechas. Later on, as they became rich in resources and obtained the resources of the spiritualized universe and the Ninefirmaments Universe, the number of twelfth-ring mechas greatly increased.
If the thirteenth ring could be used, then it would be equivalent to pushing the human civilization's technology forward.
The thirteenth ring mechas could fight a Primordial realm expert, so the next step would be the fourteenth ring, fifteenth ring, and sixteenth ring. Perhaps one day, the Limitless Empire would be able to create mechas that could rival Eternal life forms. At that time, the human civilization would be able to become a Technological Fishing civilization. As long as they had enough resources, they would be invincible.
With many cultivators and Eternal life forms, the human civilization would undergo a metamorphosis.
Of course, it would take a very long time, so long that it made people panic, but as long as there was hope, it was fine.
If other civilizations could use technology to achieve fishing, why couldn't they?
With that in mind, Lu Yin headed to the Limitless Empire with anticipation.
For a civilization that made mechas but didn't cultivate, it was difficult to live for a long time. However, it wasn't difficult for people like Shang Tianzong to live for thousands of years. They just couldn't live as long as cultivators.
It wasn't just Shang Tianzong; Shang Cheng, Shang Anan, and Elder Huan were all the same.
Elder Huan was the one who had led the research and development of the thirteenth ring energy.
When Lu Yin arrived at the Limitless Empire, a group of people greeted him. Standing at the front was the current Limitless Empire's Emperor Shang, Shang Tianshi. Behind him were the current Limitless Empire's upper echelons and the people from Shang Cheng.
Soon, Lu Yin saw the thirteenth ring energy.
Compared to the twelfth-ring energy, the thirteenth ring energy was much larger. Because it had just been created, it hadn't been put into practice yet. The Limitless Empire was simply too excited.
The thirteenth ring energy had been researched for nearly eight hundred years in Lu Yin's memories, but it was a very long time for the Limitless Empire. They had only broken through after coming into contact with other universes and obtaining new resources. If they were still trapped in the Tianyuan Universe, who knew how long it would take to create it?
Elder Huan was so excited that he forgot himself and kept introducing it to Lu Yin.
Lu Yin praised, "Thank you for your hard work, Elder Huan. With the thirteenth ring energy, we'll be able to equip our civilization on a large scale in the future. It'll become a sharp sword for our civilization."
"Hahaha, thank you, Master Lu. If you hadn't defeated the Eternals and brought us into contact with other universes, who knows how long it would have taken to break through. Thank you, Master Lu." Elder Huan bowed.
Behind him, Shang Tianshi, Shang Tianzong, and the others bowed together. "Thank you, Master Lu."
"Thank you, Master Lu …"
Lu Yin laughed. "When did you become so polite? Have you learned how to flatter me after all these years?"
Elder Huan laughed. "This is from the bottom of my heart. It's not flattery."
Lu Yin looked at the thirteenth ring energy. "This energy can erupt with the power of a Primordial Realm expert. Elder Huan, do you know what this means?"
Elder Huan was excited. "It means that a thirteen-ring mecha is enough to dominate the cultivation world. Countless cultivators can't even reach the Progenitor realm in their entire lives. Here, one mecha is enough."
Lu Yin nodded. "That's right. Countless people can't reach the Primordial Realm in their entire lives. Here, they might become assembly line products. It's very sad."
Elder Huan sighed. "Human strength is limited, but technology is limitless. This is reality. There's no other way."
Lu Yin smiled at him. "Human strength is limited, but do you know how limited it is?
Technology is limitless, but how do you know if it can be realized? "
Then, he looked up, and without any movement, the entire research base cracked open. An unimaginable force surged into the heavens, causing the stars to roll back and space to distort. It was as if the entire universe was trembling.
Next, the universe tore apart, and Sequence Strings appeared one after another. Parallel spacetime appeared, stunning everyone in the Limitless Empire. They had never seen such a scene before. Only an Eternal Realm expert who could play with the universe and bring it into a small space could do this.
However, they could see countless parallel spacetime with their minds and destroy it.
Outside the Sequence Strings was a small space, and Elder Huan and the others were led by Lu Yin to roam the small space. When they looked back, the Tian Yuan Universe was right in front of them, but it was like a palm. Lu Yin casually stretched out his hand and brought the Tian Yuan Universe into his palm. Everyone was stunned.
They had seen civilization wars and Eternal Realm experts in action, but they had never experienced this scene so realistically.
At that moment, Elder Huan's understanding collapsed. He had thought that creating thirteen rings would allow him to dominate the universe, but he had never imagined that this method would be so laughable. Thirteen rings?
No, could fourteen, fifteen, or even sixteen rings compare to this method?
Human strength was limited, and Lu Yin was clearly far from reaching his limit. But what about technology?
When he had created thirteen rings, he had the ambition to create fourteen rings, but that was all. He had never thought of fifteen or sixteen rings. That was simply unimaginable.
He could not see the limits of human strength, but technology was limitless, which allowed him to see the limits.
Their gazes shifted, and in an instant, everyone returned to the Limitless Empire from the small space. When they looked again, the thirteen rings that they had been so excited about seemed so insignificant. Under such a method, it was not even a ripple.
The change in their perception had come so quickly that it had caught them off guard.
It was as if a boundless ocean had turned into a small river in an instant.
No one could react.
Lu Yin clasped his hands behind his back and waited calmly.
After a while, Elder Huan asked in a hoarse voice, "Master Lu, what was the meaning of that?"
