According to the records in "Ten Thousand Incense Proves God Dao", after a Qi Practitioner transforms his Yang God into a Life Lamp and officially becomes a Five Realm Life God, all the incense and belief power he absorbs in the future will be extracted and refined into Incense Lamp Oil, which will then be placed within his own lamp slot.

With this lamp oil, the Life God can either absorb and integrate it into the lamp body to enhance the quality of the Life Lamp and his cultivation of magical power, or store it as a strategic resource for future needs.

The reason it can be called a strategic resource is that any spell cast directly using Incense Lamp Oil as 'fuel' will far surpass spells cast using magical power in terms of breadth, precision, and intensity.

The difference between the two is as vast as the difference between the kerosene in a lighter and the aviation fuel in a rocket.

Therefore, after extracting the lamp oil, the proportion to be used for Cultivation versus the proportion to be stored depends on the Life God's own thoughts.

However, in Li Hai's view, these Life Gods who abandon their Physical Bodies and exist solely on the incense of the common people are actually just a group of pathetic and pitiful incense parasites, which is not what he desires.

What Li Hai truly wants is for his Physical Body and Divine Soul to advance simultaneously, achieving Perfection in all aspects without any flaws, unlike a Life God who cannot survive without incense.

This kind of existence is a form of restriction, a hindrance.

Interestingly, he is not the only one in this world who thinks this way.

In the Secret Manual "Ten Thousand Incense Proves God Dao", Li Hai was surprised to find another path of cultivation entirely different from the Dao of Incense Life Lamp.

This cultivation path is called the Primal Spirit Path.

There is relatively little information about this Dao, with only a few scattered mentions in various corners of the Secret Manual.

It was through these few records that Li Hai vaguely saw the struggle of a group of people.

This group consists of Five Realm Sorcerers who, for thousands of years, have been unwilling to transform their Yang God Divine Soul into Life Lamps, stubbornly continuing to Cultivate their Yang God, and constantly exploring forward on an Unknown path, without becoming Life Gods.

These non-Life Sorcerers firmly believe that as long as they continuously temper their Yang God and constantly improve its quality, one day they may be able to Cultivate an immortal Primordial Spirit.

At the same time, in this Secret Manual, these non-Life Sorcerers of Unknown names also left some speculative descriptions regarding the various powers of the Primordial Spirit Realm.

According to the descriptions, a true Primordial Spirit Realm Sorcerer's lifespan should also be limitless; they can live as long as they wish.

Furthermore, Primordial Spirit Realm Sorcerers will no longer be limited by magical power; they may be able to effortlessly distort the natural world and reshape heaven and earth merely by using pure thought and consciousness.

At that time, such a Primordial Spirit Realm Sorcerer could be called an 'Immortal'.

To reach this Realm, according to the Secret Manual, one needs to refine and transform a certain object into a Life Lamp, rather than one's own Yang God.

This way, with an object replacing oneself as the Life Lamp, one's Yang God can continue to Cultivate, and the Physical Body does not need to be abandoned.

At first glance, this indeed seems like a win-win solution.

However, once this is done, the non-Life Sorcerer will lose the terrifying immortality of a Life God Sorcerer, who can Rebirth with just a trace of incense.

Unless they possess a resurrection-type Divine Ability, if their Physical Body and Yang God are destroyed, they will perish completely without any chance of Rebirth, utterly vanishing from the vast world.

At the same time, because the non-Life Sorcerer's Yang God has not transformed into a Life Lamp, his lifespan is not tied to incense, so how long he can live will be closely related to his Physical Body's age, longevity Medicinal Pills, and Bloodline Divine Power.

Finally, there is the tempering of the Yang God.

According to the records in "Ten Thousand Incense Proves God Dao", the non-Life Sorcerer's Perfected Yang God, which has already reached the peak of Cultivation, is an absolutely ethereal entity.

To further improve the Realm of such an ethereal entity by relying on the essence of heaven and earth would be pure fantasy.

Only by relying on Incense Lamp Oil, but absolutely not by absorbing and integrating it like a Life God Sorcerer, but by using the lamp oil as a whetstone for continuous self-refinement, can the quality of the Perfected Yang God be improved.

During this process, if the Yang God absorbs even a trace of lamp oil, it will lead to impurity and loss of its pure quality.

If too much is absorbed, the Yang God may even transform into a Life Lamp, being forced to switch from the non-Life Primordial Spirit Dao to the path of Incense Life God.

In short, the Dao of Life God is about absorbing, constantly adding.

The Primal Spirit Path, on the other hand, goes against this; it requires constant subtraction and even division, seeking ultimate purity and refinement, rather than adding more and more magical power.

However, all of this, whether for Life Gods or non-Life Sorcerers, requires the intervention of incense and belief power; otherwise, it is mere talk.

But Li Hai is different; possessing the 【Study Hard】 System, he doesn't need to gather any incense and belief power to directly advance to the Five Realm non-Life Sorcerer.

In fact, if Li Hai wished, he could even reach the end of the Primal Spirit Path in an instant and become a true 'Immortal' of the Primordial Spirit.

It's just that doing so would cause him to lose many fragments of power that he is about to obtain, so there's no real need.

This is because Li Hai also doesn't know what level of lexical entry the end of the Primal Spirit Path will be.

However, even though he doesn't need incense at all, Li Hai is very interested in it and wants to research it in depth, which led to the idea of opening the Guiyou Cave Heaven.

Moreover, he believes that since using Incense Lamp Oil to cast spells will yield extraordinary power, it seems perfectly fine to collect and store some as 'ammunition'.

With this thought in mind, Li Hai directly told Old Hu and the other villagers, as well as the refugees, his idea.

This idea was that he could open a portal to a secluded Cave Heaven, allowing them to enter and live there, where there would be enough land, enough water, and enough food (fungal cattle) to ensure survival, and their quality of life would not be poor.

But Li Hai had one condition.

That is, to enter and live in the secluded Cave Heaven, they must revere him as a God, worship him daily, and treat him like the Old Heaven.

Regarding this condition, the villagers and refugees were all puzzled, not knowing what its significance was.

To this, Li Hai surprisingly did not hide anything and directly explained to them.

He told them that their worship and faith could create a type of Incense Lamp Oil, and this lamp oil was useful to him.

That's right, Li Hai had no intention of fabricating any so-called doctrines or performing any so-called miracles to deceive and mislead these common people.

He had neither the time nor the energy, much less the interest, for such things.

Li Hai directly defined the entire matter as a transaction.

The content of the transaction was: If you believe in me and provide me with incense and belief power, then I will protect you, let you live in the safe secluded Cave Heaven, and ensure you have food so you no longer have to starve.

For this, Li Hai also specially designed a more modern set of detailed rules.

That is, everyone who enters and lives in Guiyou Cave Heaven must undergo a monthly incense KPI assessment.
