His water-attribute Spiritual Root, after reaching the Great Perfection of the tenth level of Qi Refining, had doubled in size compared to when he was at the ninth level, and the mystic power stored had also doubled.

When he reaches Foundation Establishment, his Foundation Platform will be twice as large as that of other early-stage Foundation Establishment cultivators, storing twice as much mystic power.

When cultivators reach the Foundation Establishment stage, the Foundation Platform formed by the Spiritual Root is also graded.

A supreme-grade Foundation Platform stores sixty percent more mystic power than a low-grade one.

For a cultivator who has reached the Great Perfection of the tenth level of Qi Refining, the Foundation Platform formed upon successful Foundation Establishment is bound to be a supreme-grade one.

Originally, it is twice the size of a normal Foundation Platform, plus the supreme-grade Foundation Platform stores sixty percent more mystic power than a normal one.

If you think of the Foundation Platform as a fuel tank:

A normal Foundation Platform formed by a ninth-level Qi Refining cultivator can store 1000 milliliters of gasoline.

A supreme-grade Foundation Platform formed by a tenth-level Qi Refining cultivator can store 1000×2×1.6=3200 milliliters of gasoline.

In the future, if he successfully establishes his foundation, his mystic power will be 3.2 times that of those with low-grade Foundation Platforms formed at the ninth level of Qi Refining.

The Foundation Establishment stage consists of four minor stages: early, middle, late, and Great Perfection.

Each time a minor stage is advanced, the mystic power doubles compared to before.

With the supreme-grade Foundation Platform formed at the tenth level of Qi Refining, even at the early stage of Foundation Establishment, his mystic power will be more abundant than that of a mid-stage Foundation Establishment cultivator.

The Foundation Platform not only determines the amount of mystic power stored but also represents the rate and speed of mystic power output.

To describe it in terms of strength:

Both are low-grade Foundation Platforms.

The maximum mystic power output value for an early-stage Foundation Establishment cultivator is 100.

For a mid-stage Foundation Establishment cultivator, it is 150.

In a clash of mystic power, the mystic power of an early-stage Foundation Establishment cultivator would collapse.

If we use strength as an analogy, an early-stage Foundation Establishment cultivator has 100 tons of strength, while a mid-stage one has 150 tons.

As long as he successfully establishes his foundation, his mystic power will surpass that of an ordinary mid-stage Foundation Establishment cultivator, with greater power.

This is why countless ninth-level Qi Refining cultivators strive to break through the bottleneck at the tenth level of Qi Refining.

Unfortunately, on average, only one or two out of a million ninth-level Qi Refining cultivators manage to become tenth-level Qi Refining cultivators, a very low ratio.

It is said that those with Heaven-grade Spiritual Roots above Earth-grade have a 100% chance of breaking through to the tenth level of Qi Refining.

The rarity of Heaven-grade Spiritual Roots is akin to finding a needle in a haystack.

Since the founding of the Spirit Creek Sect by the first ancestor, over 58,600 years have passed, and fewer than twenty cultivators with Heaven-grade Spiritual Roots have appeared.

In 58,000 years, on the vast lands of the Spirit Creek Sect, which are several times the size of Earth, countless cultivators have emerged, numbering in the tens of billions.

Yet, fewer than twenty Heaven-grade Spiritual Root cultivators have appeared, averaging one every two to three thousand years.

Guo Feilong now possesses an upper Earth-grade Spiritual Root, and even if he hasn't broken through to the tenth level of Qi Refining yet, once he upgrades his Spiritual Root to Heaven-grade, he can reach the tenth level of Qi Refining.

Breaking through from the Great Perfection of the tenth level of Qi Refining to the Foundation Establishment stage has at least an eighty percent success rate.

Upper Earth-grade Spiritual Roots almost guarantee a breakthrough to the Foundation Establishment stage.

Combining the two, he can break through to the Foundation Establishment stage at any time and become a Foundation Establishment cultivator.

However, he cannot break through to the Foundation Establishment stage yet because he needs to go to the Dark Forest to obtain some spiritual items that can enhance the quality of the Foundation Platform during its formation.

Once a cultivator's stage surpasses the Qi Refining stage, they cannot enter the Dark Forest, as it is a world akin to a Heavenly Abode.

He doesn't need spiritual items to enhance the quality of his Foundation Platform.

But his children will need them in the future, and besides, he has two wives and concubines who are already qualified for Foundation Establishment.

One is Sun Yufeng, who has been at the ninth level of Qi Refining for many years, and the other is Wang Yuyan, with a mid-level Earth-grade Thunder Spiritual Root.

It must be said that those with Earth-grade Spiritual Roots are indeed exceptional.

Wang Yuyan has only been cultivating for twelve years, yet she broke through to the ninth level of Qi Refining this spring.

In contrast, even if those with low-grade Spiritual Roots cultivate for 130 to 140 years, 90% of them will only reach the sixth level of Qi Refining at most by the time they die.

The gap is evident.

Of course, Wang Yuyan's rapid progress to the ninth level of Qi Refining in just eleven or twelve years is also due to her having ample cultivation resources over the years.

Otherwise, no matter how exceptional a mid-level Earth-grade Spiritual Root is, it wouldn't be possible to reach the ninth level of Qi Refining in just eleven or twelve years.

In the past two years, Guo Feilong, through the Yellow Emperor's legacy in alchemy, has reverse-engineered many alchemy recipes for various elixirs.

Among them is the recipe for refining Foundation Pills.

The spirit herbs and spirit medicines needed to refine Foundation Pills are not too rare or hard to find.

The scarcity of Foundation Pills is mainly due to the extremely low pill formation rate.

Out of a hundred furnaces and a thousand elixirs, perhaps only one Foundation Pill is produced, or even none, with the rest being waste pills.

The pill formation rate for Foundation Pills is terrifyingly low.

Another reason is that Foundation Pills are sixth-grade elixirs, and only mid-level alchemists or above can refine them.

With auspicious clouds, Guo Feilong doesn't worry about the low pill formation rate.

He has already refined 300 ninth-grade Foundation Pills, some stored in his storage bag, and some in an underground secret chamber.

No cultivator can guarantee they won't encounter unexpected death outside.

If all assets are stored in a storage bag, it would be like gifting wealth and warmth to the enemy.

So, some assets must be kept at home.

A single ninth-grade Foundation Pill is worth 300,000 Spirit Stones, and it's so rare that it's hard to buy even if you want to.

Cultivators beyond the Qi Refining stage cannot enter the Dark Forest, but there are fairies in the Dark Forest comparable to the Foundation Establishment stage.

Before heading to the Dark Forest, Guo Feilong would carve talismans that seal divine power spells on spiritual beast hides every day.

He has a water-attribute Spiritual Root and can only create talismans sealing water-attribute divine power spells and mystic power Sword Qi.

Over the past two years, he has crafted and sealed hundreds of ninth-grade talismans, and every family member with Spiritual Root qualifications has one or two of his ninth-grade talismans.

Even the Golden Body Technique reached the fourth level the day before yesterday, making his body as strong as a medium-quality Spiritual Instrument.

In these two years, Guo Feilong's various abilities and strengths have developed rapidly.

This noon, Guo Feilong sat on the back of a ninth-rank flying spiritual beast, flying alone towards the Dark Forest.

He didn't bring Wang Yuyan and Sun Yufeng because the Dark Forest, a Heavenly Abode world, is one of the most dangerous places for cultivators in the Arctic Continent's cultivation world.

Inside, the greatest danger isn't the fairies comparable to Foundation Establishment cultivators but those malicious immortal cultivators who specialize in murder and robbery.
