I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

Three years later, the Lesser Thousand Worlds were finally completed. Yang Hongbo stood in the Yang family's main square, looking at the densely packed clansmen before him, his heart filled with pride and excitement. He took a deep breath, circulated his spiritual power, and opened the entrance to the Lesser Thousand Worlds. A dazzling light flashed, and a massive portal appeared before everyone.

Yang Hongbo chanted a spell, and in an instant, Qingmang City and the four garrison cities shrank smaller and smaller, flying into the portal and quickly disappearing into it.

After entering several cities in the minor world, they landed smoothly on a large plain, and a line of words appeared on the crystal wall of the minor world: 847,529,313 living beings have settled here!

Holy crap! Where did all these numbers come from?! In the past ten years or so, the population of Qingmang City and the four major cities has only grown to a little over one hundred million, right? Upon checking, it turns out that even small creatures like ants are included in the count. If that's the case, then dealing with this number of hundreds of millions of beings is quite easy!

So Yang Hongbo found a large river, opened a huge portal to block it, and the river flowed into an even larger river in the smaller world.

Meanwhile, the numbers on the crystal wall of the minor world were also growing rapidly, reaching billions, tens of billions, hundreds of billions, and finally, the number of billions of living beings had been filled.

It turns out there were too many plankton in the river, not to mention so many fish.

Qingmang City and the four great cities landed on a plain covering tens of thousands of miles. Everyone in the city was shocked to find that the spiritual energy here was too rich. Even if they did not ascend to the immortal realm, it was already a blessing to be alive in the present!

After bringing several cities into his minor worlds, Yang Hongbo toured the northern border again, collecting a large number of low-level demonic beasts and bringing them into various minor worlds. Next, he would slowly transplant various spiritual herbs and medicines and relocate various demonic beasts into these minor worlds.

He took out a teleportation array plate, and with a flash of light, Yang Hongbo returned to the cave of the Bobai Immortal Sect. Several years had passed, and everyone thought he was still in seclusion.

Having raised his cultivation to the peak of the Mahayana stage, Yang Hongbo stepped out of the cave.

With a swift movement, he transformed into a streak of light and flew towards the spirit herb garden of the Bo Bai Immortal Sect. In the garden, various rare spirit herbs thrived under the nourishment of spiritual energy, emitting an alluring fragrance. Looking at these herbs, Yang Hongbo secretly plotted how to transplant them into his minor world.

Just then, a disciple of the Bo Bai Immortal Sect happened to pass by. Upon seeing Yang Hongbo, he quickly stepped forward and bowed, saying, "Senior Brother Yang, you've emerged from seclusion? Your cultivation must have improved considerably during these past few years of closed-door training!"

Yang Hongbo smiled slightly and said, "Junior Brother, you flatter me. I've only gained a slight understanding. By the way, I came out of seclusion this time to select some spiritual herbs from the Spirit Herb Garden and transplant them to a secret location. I wonder if that's possible?"

Upon hearing this, the disciple looked troubled: "Senior Brother Yang, the spiritual herbs in this herb garden are all treasures of the sect. If we want to transplant them, we need the sect leader's approval."

Yang Hongbo pondered to himself that going directly to the sect leader might arouse suspicion, as the matter of a thousand minor worlds was far too significant to be easily revealed. So, a thought struck him, and he said, "Junior brother, don't worry, I will naturally report to the sect leader. However, I need your help with this matter. Before I report to the sect leader, could you please keep an eye out for which spiritual herbs are suitable for transplantation?"

Seeing Yang Hongbo's response, the disciple couldn't refuse any longer and could only nod in agreement: "Alright, Senior Brother Yang, I'll keep an eye out for you. However, you must report to the sect leader as soon as possible."

Yang Hongbo nodded and smiled, "Of course, thank you very much, junior brother."

After saying that, he vanished from the spirit herb garden in a flash. The disciple watched Yang Hongbo's departing figure, muttering to himself, "Why does Senior Brother Yang seem a little mysterious this time after his seclusion?"

After leaving the Spirit Herb Garden, Yang Hongbo didn't go directly to the sect leader. Instead, he went to the Monster Beast Garden of the Bobai Immortal Sect. In the garden, various monsters roamed freely, some ferocious, others gentle and adorable. Looking at these monsters, Yang Hongbo secretly plotted how to bring them into his Lesser Thousand World.

At this moment, a disciple responsible for taking care of the demonic beasts saw Yang Hongbo and quickly stepped forward to bow: "Senior Brother Yang, what brings you here? Are you here to choose a demonic beast as a mount?"

Yang Hongbo shook his head and said, "Junior brother, I came to the Monster Beast Garden this time to select some monsters and relocate them to a secret location. Is that alright?"

Upon hearing this, the disciple looked surprised: "Senior Brother Yang, you want to relocate the demon beasts to the secret realm? This is no small matter; it requires the sect leader's approval."

Yang Hongbo inwardly sighed, thinking to himself that he needed the sect leader's approval everywhere he went. However, he remained outwardly calm and said, "Junior brother, don't worry, I will naturally report to the sect leader. However, I need your help with this matter. Before I report to the sect leader, could you please keep an eye out for which demonic beasts are suitable for relocation?"

Seeing Yang Hongbo's words, the disciple, though somewhat doubtful, could not refuse further and could only nod in agreement: "Alright, Senior Brother Yang, I'll keep an eye out for you. However, you must report to the Sect Master as soon as possible, otherwise, I cannot bear the responsibility if anything goes wrong."

Yang Hongbo nodded and smiled, "Of course, thank you very much, junior brother. By the way, junior brother, I hope you can keep my selection of demonic beasts and spiritual herbs a secret and not let anyone else know about it."

Upon hearing this, the disciple quickly nodded in agreement: "Don't worry, Senior Brother Yang, I will absolutely not reveal it to anyone else."

Yang Hongbo nodded in satisfaction, then vanished from the monster garden in a flash. The disciple watched Yang Hongbo's departing figure, muttering to himself, "What on earth is Senior Brother Yang up to this time? Why is he being so mysterious?"

Over the next few days, Yang Hongbo wandered around the Bobai Immortal Sect, exchanging ideas with the disciples, while secretly observing the situation in the Spirit Herb Garden and the Monster Garden. He discovered that there were indeed some rare spiritual herbs in the Spirit Herb Garden suitable for transplanting to the Lesser Thousand World, and some monsters in the Monster Garden suitable for relocation.

Therefore, he decided to find an opportunity to report this matter to the sect leader. However, before reporting, he needed to make thorough preparations to avoid arousing the sect leader's suspicion.

On this day, Yang Hongbo arrived at the sect leader's cave dwelling and requested an audience. After a short while, a disciple emerged from the cave and said to Yang Hongbo, "Senior Brother Yang, the sect leader is currently in seclusion. If you have any matters to discuss, please inform me first, and I will relay your message after the sect leader emerges from seclusion."

Upon hearing this, Yang Hongbo thought to himself: The sect leader is currently in seclusion, this is a good opportunity. So he said, "Junior brother, I have come to see the sect leader to report something about the sect's secret location. This matter is of great importance and requires the sect leader's personal decision. However, since the sect leader is currently in seclusion, I will inform you first, and you can relay the message to him after he emerges from seclusion."

Upon hearing this, the disciple's expression turned serious: "Senior Brother Yang, please speak. I will remember it well and convey it to you as soon as the Sect Master emerges from seclusion."

Yang Hongbo nodded, then lowered his voice and told the disciple about his plan to transplant spiritual herbs and relocate demonic beasts to the Lesser Thousand World. However, he didn't mention the specifics of the Lesser Thousand World, only saying that it was a secret place.

After hearing Yang Hongbo's account, the disciple looked surprised: "Senior Brother Yang, is what you said true? Can that secret place really hold so many spiritual herbs and demonic beasts?"

Yang Hongbo nodded and said, "Of course it's true. How could I joke about something like this? However, this matter still requires the sect leader's approval. Therefore, I hope that you will convey this to me as soon as the sect leader comes out of seclusion."

The disciple quickly nodded in agreement: "Don't worry, Senior Brother Yang, I will keep it in mind and convey it to you as soon as the Sect Master comes out of seclusion."

Yang Hongbo nodded in satisfaction, then turned and left the sect leader's cave. He thought to himself: Now, all I need to do is wait for the sect leader to emerge from seclusion and see if he agrees to my plan. However, even if the sect leader disagrees, I have ways to proceed secretly. After all, a thousand minor worlds are a high-level treasure, and I can't easily reveal it to others.
