When Guo Feilong returned home, it was already around eleven at night.
He sneaked into the room of the quadruplet sisters.
What happened next is omitted for a hundred thousand words.
It wasn't until the sun was high in the sky that Guo Feilong, feeling refreshed, emerged from the room of his beautiful concubines.
After lunch, Guo Feilong gathered all his wives and concubines in the family meeting hall.
He inquired if anything had happened at home during his absence.
The result was that everything at home was fine, with nothing significant occurring.
A few of his wives and concubines, who had some talent in alchemy, had advanced from apprentice level to low-level alchemists during his absence, now able to refine first, second, and third-grade elixirs.
Several others, who showed some talent in artifact refinement, also progressed from apprentice to low-level artifact refiners while he was away.
Additionally, a few wives and concubines with talent in formations and talismans had advanced from apprentice level to low-level formation masters and talisman masters.
Moreover, thirty thousand ordinary people had been relocated from outside to this First Grade Small World, establishing dozens of villages and towns.
In the eight or nine months he was away, many children he had not yet met were born.
Children with spiritual roots would have their spiritual root grades increased by one or two levels, with the lowest being medium quality.
Currently, the total number of his children had exceeded a thousand.
Although he, as a father, had no time to accompany these children, fortunately, their mothers did.
In the following two months, Guo Feilong worked hard every day to ensure his wives and concubines became pregnant.
Unfortunately, those who had already given birth to eight or nine, or even more than ten children, found it difficult to conceive again, as if they had reached a limit.
No matter how hard he tried or how well he cared for them, they just wouldn't get pregnant, as if they had undergone sterilization.
The more wives and concubines he married and the more children he had, the more auspicious clouds would be generated in the Family Fortune Cauldron.
As Guo Feilong's cultivation stage improved and the grade of elixirs he refined increased, the consumption of auspicious clouds also grew.
Fortunately, when his children with spiritual roots broke through their cultivation stages, it contributed to the family's strength, and the Family Fortune Cauldron would produce auspicious clouds.
During his time back, Guo Feilong also visited the Spirit Creek Sect's Heavenly Abode headquarters to submit several elixirs that needed to be handed over.
Because he had gained enough cultivation resources from the Northern Borders Continent's cultivation world, Guo Feilong adhered to the principle of keeping a low profile.

He did not certify himself as a high-level alchemist at the sect's Alchemy Peak, as making a fortune was what he enjoyed.
He went to the Spirit Creek Sect's Heavenly Abode headquarters, using Ninth Grade Foundation Pills and a large number of spirit stones as a bride price.
He successively married over a dozen beautiful inner disciples of the Spirit Creek Sect. Although he wasn't a groom every day, he could marry three to five wives and concubines each month, living a happy and joyful life.
In the days since his return, Guo Feilong had been busy crafting a large number of high-level formation bases and formation flags.
From that Fourth Grade Heavenly Abode small world, he obtained three Ninth Grade spirit fruit trees, a Ninth Grade spirit tea tree, and several Seventh and Eighth Grade spirit herbs and medicines.
Some of these spirit herbs and medicines were scarce and in high demand on the market, so they needed to be transplanted into the Guo family's Heavenly Abode small world.
After more than half a year of preparation, Guo Feilong finally completed the formation bases and flags needed for his grand formation. The materials alone cost a staggering 120 million spirit stones.
The formation arts passed down from the Yellow Emperor differed greatly from those in the cultivation world.
First, the Yellow Emperor's formation arts utilized the principle of leverage.
With minimal cost, they could mobilize the surrounding mountains, rivers, and earth veins to form a powerful formation.
A single formation could encompass attack, defense, illusion, and transformation, creating a comprehensive mixed formation.
In contrast, the formations in the cultivation world were generally more singular in function. A defensive formation was solely for defense, a killing formation for attack, and an illusion formation for illusions.
They could layer formations within formations, but a single formation couldn't encompass multiple types.
Moreover, the power of formations in the cultivation world heavily depended on the quality of the formation tools. The higher the grade of the tools, the more powerful the formation.
They had no concept of harnessing the power of mountains, earth veins, and rivers.
When comparing the two, even with the same grade of formation tools, the Yellow Emperor's formation arts were more potent.
Guo Feilong mapped out the entire First Grade Small World, including all mountains, earth veins, and rivers.
The small world had a circular sky and square earth shape. Guo Feilong divided it into nine regions based on the principles of Yin-Yang, Five Elements, Eight Trigrams, and Nine Palaces.
He then identified the best location for the grand formation, a place with mountains to the west and back, a winding river to the east, and flat terrain to the south, covering an area with a diameter of about six to seven kilometers.
Guo Feilong combined the Yellow Emperor's formation arts with the local formation arts of the cultivation world.
He spent over three months placing high-level formation stones beneath every mountain, within every river, and in every lake, connecting the entire small world's energy.
Using the entire small world as the Yin-Yang Nine Palaces Eight Trigrams formation plate, Guo Feilong set up eighty-one formation bases and flags in the six-kilometer diameter area he selected.
The grand formation he intended to set up was one of the powerful formations passed down by the Yellow Emperor, called the Yin-Yang Five Elements Divine Beast Formation, capable of both defense and offense.
It took Guo Feilong a whole year to complete the setup of the Yin-Yang Five Elements Divine Beast Formation, finally finishing this afternoon.
Next, he needed to activate the formation and set it in motion.
"Rise!"
Guo Feilong cast a spell onto the most crucial formation stone to activate the grand formation.
In the next moment, accompanied by a rumbling sound from the earth, the entire small world seemed to experience an earthquake.
"Don't panic, it's just me activating the grand formation," Guo Feilong announced, reassuring everyone not to worry.
At this moment, Guo Feilong flew high into the sky and looked down. The ground of the entire small world displayed glowing veins, resembling human blood vessels.
Moments later, the formation was fully activated, and the glowing veins on the ground vanished, replaced by thick white fog in the six-kilometer diameter area he designated.
Guo Feilong flew into the white fog, where visibility was less than a meter, and everything appeared blurry.
The white fog had no offensive capability, only the ability to block divine sense and vision, rendering divine sense ineffective within.
Guo Feilong, as the master of the formation, had his divine sense unaffected in the white fog. Anyone wearing a formation token he crafted would also have their divine sense unaffected.
Passing through about a hundred meters of white fog, one would enter the killing zone of the Yin-Yang Five Elements Divine Beast Formation.
If someone attempted to force their way in without a formation token, the formation would summon the divine statues of the Orient Loong God in the east, the Rosefinch in the south, the White Tiger in the west, and the Basalt in the north to attack the intruder.
Even if the divine statues were shattered, they could be infinitely reformed. Their power was so formidable that even a late-stage Golden Elixir cultivator would meet their end.
As for whether the formation could kill an Elemental Infant stage cultivator, Guo Feilong hadn't witnessed an Elemental Infant cultivator in action, so he wasn't sure.
If someone proficient in formations and extremely powerful forced their way through the killing zone, they would enter the defense zone of the Yin-Yang Five Elements Divine Beast Formation.
Here, the defense zone was covered by a two-foot-thick earth-yellow defensive light screen.
If the defensive light screen was attacked, the earth's spiritual energy would condense into a Kylin statue, boosting the defense formation's power up to thirty times. Even if an Elemental Infant stage cultivator came, Guo Feilong was confident in holding them off.
Inside the defensive light screen was a safe area with a diameter of three kilometers, containing a large Gathering Spirit Array.
The spiritual energy within this three-kilometer area was at least thirty to forty times more abundant than outside.
In the grand scheme of the universe, everything is balanced. Because the spiritual energy here was so abundant, the rest of the small world had slightly thinner spiritual energy than before, but not significantly so.
Guo Feilong transplanted the spirit fruit trees he obtained from the Fourth Grade Heavenly Abode small world, along with some rare Seventh and Eighth Grade spirit herbs and medicines, into this area.
After activating the formation and transplanting the high-grade spirit herbs, medicines, and fruit trees, Guo Feilong returned home. Within ten minutes, one of his beautiful concubines gave birth to nine children.
