Starting as a spiritual plant master, may I eventually become the master of all lands.

Regarding foundation building, Song Chuan had already consulted the records at Yuewei Hall.

The final part of the "Na Tu Jue" technique also fully describes the foundation-building process.

This common basic cultivation method actually has one advantage: it contains everything that should be included and has been verified by the vast majority of low-level cultivators in the cultivation world.

Generally speaking, most people's choices are unlikely to be wrong. As for increasing the chance of Foundation Establishment, don't even think about it.

Foundation building actually involves three steps, the first of which is marrow cleansing and bone tempering.

Although Qi Refining cultivators breathe in spiritual energy day and night, their bodies are not fundamentally different from those of ordinary people.

Their lifespan is only about 120 years, while some ordinary people can live to be over 100 years old.

Although mortals always experience war, disease, famine, and other disasters, and a lifespan of fifty or sixty years is considered a long life, how many Qi cultivators can die peacefully in their old age?

Behold, the strange sights of Kongsang have claimed the lives of countless young men.

The acupoints, meridians, and bones of Qi Refining cultivators belong to the category of those who have just emerged from the mortal realm, but have not completely separated themselves from it.

To become a Foundation Establishment cultivator, the first step is to cleanse the marrow and refine the bones, which builds the physical body.

Cleansing the marrow and bones is not as simple as taking a few pills to wash away impurities; it requires completely discarding all worldly aura.

This test examines a cultivator's "essence," which is the essence in the commonly referred to "essence, energy, and spirit."

If a Qi Refining cultivator indulges in excessive sexual activity, becomes physically weak, or suffers irreversible damage to their physical body, resulting in insufficient essence and Qi, it will be difficult for them to sustain a long period of marrow cleansing and bone tempering during the Foundation Establishment stage.

Because during the marrow cleansing and bone-refining process, cultivators experience excruciating pain, as if their bones are being scraped by a steel knife and their marrow is being drenched by spiritual water.

Song Chuan was an earth-elemental cultivator. Although his cultivation technique was not advanced, it was quite beneficial to his physical body. In addition, he was still a virgin, so his vital energy was abundant, which went without saying.

However, this is only a basic requirement; a Foundation Building Pill is still needed to slightly alleviate the pain.

The second step in Foundation Building is to open the three apertures, which are known in the cultivation world as the "Three Passes of the River Chariot".

After the marrow cleansing and bone tempering are completed, the cultivator must immediately gather his magical power, starting from the lower dantian, going to the perineum, and then traveling in reverse along the Du meridian on the spine to break through the three largest acupoints: the coccyx, the Jiaji acupoint, and the Yuzhen acupoint.

Then the magic power arrives at the upper dantian, the "Niwan Palace," and after arriving at the Niwan Palace, it begins to descend, which is much simpler.

The magical power travels from the Chengqi acupoint below the eyes to the Tiantu acupoint in the throat, then down to the Tanzhong acupoint in the middle dantian, and finally back to the lower dantian.

This step is to connect the three dantians and form a complete circulation!

Because cultivators use their magical power to break through barriers, much like driving a car across a river, it is also called "River Cart Breaking Through Barriers".

Among them, the coccyx, ligament, and occipital points are located on the spine of the back of the human body and are the three most crucial acupoints, which are extremely difficult to penetrate with magical power.

This spine is of paramount importance; the reason why humans are human is closely related to this spine and the acupoints on it.

All demons who wish to transform must cultivate a spine similar to that of humans, which is precisely why the transformation of insectoids is the most difficult.

They don't even have any other bones, let alone a spine!

Animals, birds, and even fish with a spine must have their acupoints moved or created to be equivalent to the human spine!

Besides reducing the pain of marrow cleansing and bone tempering, the core function of the Foundation Building Pill is to assist cultivators in breaking through the three major barriers on the spine!

Once the three barriers are overcome and the three energy fields are connected, the cultivator must proceed to the final step: liquefying spiritual energy!

Qi cultivators, especially those with poor aptitude, have bodies like sieves, making it extremely inefficient to convert the spiritual energy they absorb into magical power; much of the spiritual energy leaks away in the blink of an eye.

The spiritual energy stored in its lower dantian is even more chaotic, with several kinds of spiritual energy from the five elements intertwined.

There is still a lot of spiritual energy in the meridians and acupoints, which neither leaks out nor sinks to the dantian, becoming waste spiritual energy and hindering the flow of magical power.

The process of liquefying spiritual energy involves a cultivator channeling all their spiritual energy into their dantian, and then purifying that energy to the specific attribute they are cultivating.

After being purified to a certain degree, this spiritual energy becomes liquid and flows continuously, forming the Qi Sea and Dantian!

If the medicinal power of the Foundation Establishment Pill was not exhausted during the second step of the River Chariot Three Gates, it can now help cultivators purify their spiritual energy.

Once the Qi Sea and Dantian are formed, the Qi Refining cultivator transforms into a Foundation Establishment cultivator. Only then can they truly transcend the realm of mortals and formally step into the gate of immortal cultivation.

In the early stages of Foundation Establishment, the lifespan is 240 years. Each breakthrough in a minor realm increases lifespan by 20 to 30 years!

When Song Chuan thought of the matter of lifespan, he smiled crookedly. This was to prevent cultivators from becoming complacent after reaching a certain level.

Some people may not care, but there are definitely some who are willing to take the plunge!

Those cultivators who take a gamble might not be as good as those who give up; they might even die in some secret realm or while vying for spiritual treasures in their pursuit of advancement.

He cleared his mind of distractions, silently rehearsing the three steps of Foundation Establishment several times. He patted his storage bag and took out an incense burner. He lit a calming incense stick, and the smoke curled up, filling the entire spiritual room.

He then opened the two porcelain bottles containing Foundation Establishment Pills, placed them in front of him, made a hand seal with a blank expression, and sat cross-legged in meditation.

A moment later, he quickly picked up a Foundation Establishment Pill and swallowed it.

Immediately afterwards, he suddenly gathered all his magical power, quickly changed to a sitting posture with his palms facing upwards, his whole body trembled, and he began to cleanse his marrow and bones!

His facial expressions shifted between pain and twitching, and his body sometimes swayed violently, almost causing him to lose his seated posture with his palms facing upwards.

After persisting for several days, all 360 acupoints suddenly opened, and streams of black fluid flowed out, gathering into a pool of black water beneath him.

The black water had no smell and quickly dissipated. Its origin and destination were unknown.

A month passed after all the black water drained out and disappeared.

Song Chuan let out a soft breath and immediately gathered the magical power in his dantian. The magical power flowed down from the dantian to the perineum and rushed straight to the first gate, the coccyx acupoint.

The acupoints were completely different from when the black water had just been expelled; they were firmly guarding their entrances, refusing to let any magical power in.

Although Song Chuan's magical power, cultivated with the help of the beads, was pure, he estimated that it would take him at least a month to open up the coccyx acupoint on his own.

At this moment, another force within his body merged with his magical power—the effect of the Foundation Establishment Pill. The two forces combined and impacted his coccyx acupoint.

A month and a half later, Song Chuan looked exhausted, yet with a hint of joy. He had passed the three trials of the River Chariot, but it had taken him fifteen days longer than others!

This past month and a half has been like a siege, and without the Foundation Establishment Pill, I would have given up in despair long ago.

Those with decent aptitude and three spiritual roots will complete this step within a month.

The next step is to liquefy spiritual energy to form the Qi Sea and Dantian, but the effects of the first Foundation Establishment Pill have already been exhausted.

He swallowed the second Foundation Establishment Pill, then changed his hand seals and meditation posture, and the spiritual energy in his limbs and bones began to slowly gather in his lower dantian.
