Lu Yin brought Progenitor Chen to the highest peak on Earth, allowing the planet to rotate as they watched the stars.
To them, no matter where they stood, they could clearly see the stars in the sky. Just as Lu Yin had said, he had chosen Earth to get a good omen.
Ten years passed, and Lu Yin was still looking at the stars. Earth had day and night, but their gazes transcended the heavens, and the stars never left their sight.
Another ten years passed, and Lu Yin was still looking at the stars. He looked at the stars that he was familiar with, hoping to incorporate them into the Astral Fist Manual and find his own fist intent.
Ten years after ten years, ten years after ten years.
It had been forty years since they had arrived on Earth.
On this day, meteors streaked across the sky, and the night sky was beautiful. Lu Yin's gaze returned to Earth, and he watched the meteor shower with countless earthlings. Each meteor was like a fist intent that streaked across the sky. He hoped to grasp these fist intents, but they were not real. Every fist intent needed to be comprehended, and he could do it, but it would take a long time.
He looked at Progenitor Chen, and he didn't know when it had started, but Progenitor Chen's aura had become incomparably calm. The fist intent that he had comprehended over a thousand years had completely dissipated, but it had not disappeared. Instead, it had merged into the stars in the distance.
What was that???
These stars had originally come from Progenitor Chen and Sirius Art.
In the past, Lu Yin had used these stars to defeat powerful enemies and save respected seniors. Now, these stars carried Progenitor Chen's fist intent, and they were connected to each other as they gradually spread throughout the entire sky.
Lu Yin knew that Progenitor Chen had comprehended something.
He had made the right choice in asking Progenitor Chen for help. Not only did Progenitor Chen possess an unparalleled talent for battle techniques, but he was also compatible with the stars in the sky. The Sirius Art that he had created had seamlessly merged with the Astral Fist. In Lu Yin's eyes, his Astral Fist Manual had changed.
The stars arranged themselves into a familiar starry sky, like a miniature Milky Way. They gradually floated, and finally, with Progenitor Chen at the center, the world spun.
Progenitor Chen opened his eyes, raised his arm, and punched out. The stars lit up, and he followed up with another punch. The stars revolved and were constantly lit up. It was like the Sirius Art, but also the Astral Fist.
With a bang, the starry sky trembled as numerous stars lit up. The might of Ancestor Chen's punches grew stronger and stronger, but the time it took for each punch to be unleashed grew longer and longer.
Ten years, twenty years, fifty years went by, and more stars were lit up as Progenitor Chen continued to unleash his punches. The Astral Fist Manual continued to expand and spread towards the Outerverse.
Lu Yin did not disturb him. He just watched as Progenitor Chen threw out countless punches. Right now, the power of a single punch from Progenitor Chen was enough to rival a Limit expert below Eternal Immortality. Progenitor Chen was only in the Primordial realm right now. He had relied on the Nirvana Tree's cultivation method to cross realms and reach Great Perfection.
The Nirvana Tree technique was also a way for many experts in the three universes to challenge those of a higher realm.
However, regular cultivators would only be able to challenge ordinary Bitter Tribulation experts as Primordial realm experts at most. Those who were close to Great Perfection of Bitter Tribulation were on another level.
Ancestor Chen did it, shocking countless people.
Now, he had relied on his own comprehension of the Astral Fist to surpass Great Perfection of Bitter Tribulation, reaching the limit below Eternal Immortality. If he took another step forward, he would be a rogue.
In the current human civilization, powerhouses like Qing Xing, Dan Hong, and the Great Master had once reached the limit below Eternal Immortality. They could use the Eternal Substance to fight, and they could use the Nirvana Tree to reach the level of a rogue. However, they were all at the limit below Eternal Immortality. They were not like Progenitor Chen, who had crossed realms and reached the level of a rogue.
There were very few people who could do this, and now, Progenitor Chen had appeared.
Lu Yin was very certain that once Progenitor Chen set foot in Bitter Tribulation, he would be able to reach the level of a rogue with the Nirvana Tree and the Astral Fist.
Another fifty years passed before Progenitor Chen slowly pulled back his arm.
He had punched for a hundred and ten years, and Lu Yin did not even bother to count how many stars he had lit up. This was Progenitor Chen's own Astral Fist Manual, and the stars he had lit up were far from enough for the entire manual.
However, Lu Yin was already satisfied.
If Progenitor Chen could reach this step, it meant that he could completely light up his Astral Fist Manual. When that time came, the power of his Astral Fist would be enough to make people look forward to it.
At the same time, it also proved that this path could be taken.
Progenitor Chen raised his head and looked at the sky for a long time before turning back to Lu Yin. "My Astral Fist Manual is completely different from the one you helped me to comprehend. Although I have walked my own path, this path is very narrow, so narrow that I can't breathe."
"Senior, what do you mean?" Lu Yin did not understand.
Progenitor Chen looked into the distance in a daze. "I will do my best to widen this path, and …" He paused for a moment. "I am about to reach the level of Bitter Tribulation." Lu Yin was surprised and smiled. "Congratulations, senior."
?????
"When I reach the level of Bitter Tribulation, we will test the Astral Fist together. I believe that I will have other insights by then, so you don't have to rush."
"Of course, we won't wait too long. When I reach the level of Bitter Tribulation, we will enter the mirage domain to test the Astral Fist together. It will be very quick."
"Alright." Lu Yin understood.
Progenitor Chen left Earth. Lu Yin did not know where he was going, but it must be related to Bitter Tribulation.
He hoped that Progenitor Chen would be able to find his true Bitter Tribulation.
Since he was on Earth, he might as well visit his old friends.
With a sweep of his consciousness, he knew the situation on Earth like the back of his hand.
Several old friends were there.
Lu Yin teleported to Nanjing, where he found Zhou Shan watering the flowers in an antique courtyard.
Zhou Shan had aged a lot since he had lived for thousands of years. His cultivation was actually very low, and if not for the resources he had used to forcefully raise his cultivation, he would not have been able to live until now. He looked weathered, but his mental state was good.
Knock knock knock.
"Who is it?"
"An old friend." Zhou Shan, who was watering the flowers in the courtyard, suddenly paused and looked up. Was this … Lu Yin?
He hurried over to open the door and saw Lu Yin.
Lu Yin smiled at him. "Long time no see." Zhou Shan looked at Lu Yin and was so excited that he did not know what to say. "Please come in, quickly come in." Lu Yin smiled and walked into the courtyard.
The courtyard was not large, and with Zhou Shan's status, he could have a courtyard of any size he wanted. He could even enter the Above Sky Sect. However, he had spent his entire life on Earth and would not go anywhere. To him, material pursuits were a thing of the past, and memories were the most precious.
"Take a seat, I'll make some tea." Zhou Shan was busy, and Lu Yin did not stop him. He was very happy to see an old friend again.
How long had it been since he had last met Zhou Shan?
More than two thousand years. Such a long time seemed like a lifetime to Zhou Shan, but to Lu Yin, it was very, very fast.
It had been 170 years since he had entered Earth, and in the blink of an eye, 170 years had passed, but Lu Yin felt nothing.
Time seemed fair, but it felt different for different people.
He had come to Earth during this period and seen Zhou Shan, but he had not disturbed him.
Compared to the last time they had met, Zhou Shan and his daughter Zhou Xixi had been rather reserved. Now that Lu Yin's status was higher, Zhou Shan was more relaxed, as if they were really old friends.
Lu Yin was busy for a while before settling down.
There was tea, snacks, and a booklet in front of Lu Yin.
Lu Yin curiously picked up the booklet and flipped it open. It was filled with images of people.
"What's this?" Zhou Shan said, "I'm old, and I'm afraid I'll forget them, so I drew them out to reminisce."
The booklet was filled with people he had encountered during Earth's apocalypse. Lu Yin recognized some of them, and some of them he did not.
Some of them even held grudges.
But to Zhou Shan, they were all memories.
There was Li Hongliang, the strongest captain of Jinling's penal camp, Feng Hong, Luo Yun, Qin Xuan, Huan Sha from the capital, Elder Lian, and so on.
Lu Yin flipped through them one by one, his memories flowing and gradually becoming clearer.
He had not forgotten these, but with thousands of years of memories and Lu Xiaoxuan's memories, there were many things that did not need to be remembered.
Zhou Shan was different; he only had these memories.
He had not left Earth much in his life, and these memories were extremely precious to him.
He flipped to the last page.
It was Zhou Xixi and many other members of the Zhou family. He had placed the genealogy with the people in his memories.
Lu Yin put down the booklet, "You can live for a long time. If nothing unexpected happens, the resources will be enough to push you to the level of an Emissary. There's no need for this." Zhou Shan laughed and waved his hand, "I rejected those resources."
"Why?"
"It's good to live for a long time, but it's hard to watch old friends leave one by one."
Zhou Shan smiled at Lu Yin, "I'm really happy that you came to see me. I thought we would never meet again." Lu Yin picked up the teapot and poured tea for Zhou Shan.
If it had been the Zhou Shan of two thousand years ago, he might have felt somewhat restrained, but now he truly regarded Lu Yin as an old friend.
Lu Yin took a sip of tea and looked at him, "Do me a favor." Zhou Shan did not understand, "What can I do for you?" Lu Yin's voice was melancholic, "Help me keep my memories."
"What do you mean?"
"He's alive." Zhou Shan was taken aback. "Is it helpful?"
Lu Yin nodded and looked him in the eye, "Everyone has the right to choose between life and death. Your experience may have made you wish to face death normally, and I'm being selfish by doing this. But to me, if you live, then it means that my past is also alive."
"But you have many old friends around you."
"As time passes, even if
