In order to find out why "black silk threads" were born in this ore vein, Su Xing sat cross-legged and waited silently.

After a long time.

As the monks finished their work one after another, Su Xing was the only one left in the mine.

He looked around and confirmed that no one was observing him. He immediately started a state of "civilization" and quickly penetrated into the ore vein.

Strictly speaking, the spirit stone veins in Heicheng are renewable resources.

Although there are monks in the mines that are mining day and night, new veins will be generated from the cave every ten days and a half months.

The faster the monks mine, the faster the spiritual stone veins are generated, and the specific reason is unknown.

In this way, a perfect virtuous cycle was formed.

Some lower-level monks with higher working years have worked in the Heicheng mine for decades, and even worked until they died.

Most of the descendants of these lower-level monks became mortals again because they did not have the talent for cultivation, so they were unable to become powerful.

Some mortals, because they were born with the Purple Mansion, were promoted to the lower level of monks, so they had hope.

This process seems to be a promotion, but it is essentially a labor force, at best it is just a change in the place of labor.

‘Maybe, can there be a cultivator among my children?’

With this idea, the mortals in the Black City have been working for hundreds of years, and so the descendants are endless.

They dug countless spirit stones for Black City.

Countless monks at the bottom, ordinary people live and die, but the gods and high-level monks are eternal and unchanging.

Inside the ore vein.

Just like Su Xing’s guess.

After he entered it, he found that there was indeed a unique world inside the spirit stone vein.

The ore veins contain not the extremely rich spiritual energy or a large number of spiritual stone ore, but countless corpses piled up into mountains!

And these corpses are also the reason why the "black silk thread" is emitted in the ore veins...

At first glance, some of these corpses were old and some were young.

There are monks and mortals.

They all had a life span of only one to two days left on their chests, and were killed by some special means and transported to this place.

As for the role of these corpses being placed in the spirit stone vein...

Su Xing found that there were densely packed "crystalline mushrooms" on the surface of these corpses.

Unlike the 'crystal mushroom' that grows from the ground.

These mushrooms that grow from the corpses of mortals and monks have translucent surfaces and look like glass-like crystals.

in.

Some of the "crystal mushrooms" that have grown for a long time have gradually changed from translucent to dark gray.

These mature 'crystal mushrooms' have more texture like rocks...

Or spiritual stone ore.

After discovering this, Su Xing immediately understood:

The so-called spirit stone veins in this mine actually do not exist naturally, but are formed by countless dead people who have eaten "crystalline mushrooms".

The reason why the Heavenly Court established a human settlement again was not for the mineral veins here.

Black City produces a lot of ‘crystal mushrooms’, and mushrooms can feed a large number of humans.

After the humans who eat mushrooms die, they can form spirit stone veins, which can produce a large number of spirit stones...

And this may be the true meaning of Black City's existence.

In order to facilitate distinction, Su Xing still called the mushrooms planted in the ground 'Crystal Mushroom'.

The mushrooms born from human flesh and blood are called "flesh mushrooms".

He maintained a state of treacherousness and continued to observe inside the ore veins...

The 'Flesh and Blood Mushroom' is born from the flesh and blood, and will gradually crystallize and solidify into a spirit stone ore.

In this way, the 'Flesh and Blood Mushrooms' are divided into two forms:

The first one is a growth period of "flesh and blood mushrooms" that were born for a period of time, and were translucent in overall shape and resembled glass.

The second type is the mature "flesh and blood mushroom" that has become mature, has a gray surface, and is about to form a spiritual stone ore.

certainly.

In addition to these two forms, there are also a small number of corpses on the surface, with the newly born "flesh and blood mushrooms".

It is precisely because they were born that these "flesh and blood mushrooms" appear between flesh and blood and translucent crystals.

These "flesh mushrooms" are indeed transformed from flesh and blood...

This made Su Xing think a guess.

First of all, his world is not a novel, but a real world with reasonable logic.

Therefore, all things in the universe must follow the law of conservation of matter, and energy cannot be produced out of thin air.

Then the same is true for spiritual energy. Its birth must have a certain source...

From this, it is not difficult to guess whether the spiritual energy that permeates this world and is everywhere comes from human flesh and blood?

And if we go further, we speculate.

Since the spiritual power of the entire world comes from the flesh and blood of humans...

Then equivalent replacement.

Is the behavior of the demons and monsters in this world confusing humans and devouring humans equal to the monks absorbing spiritual power between heaven and earth?

For example, the "Longevangel" who absorbs the essence, qi, blood and flesh of a person who is about to die...

Of course.

Among these many strange things, there is also an existence that is transcendent beyond the object, which Su Xing cannot understand.

——That is an indescribable creature.

The indescribable organisms feed on human lifespan, and the concept of lifespan is not physically physically.

To understand all this and know more secrets, Su Xing needs to have stronger cultivation and come into contact with more things...

The "flesh and blood mushrooms" in the spirit stone veins grow very fast.

Just a moment when Su Xing entered the ore vein, more than a dozen mushrooms gradually grew from glass to spiritual stone ore.

It is estimated that at most one night, all the human corpses inside the ore will be converted into spiritual stone ore.

Perhaps it is precisely because of this that the monks have never discovered the secrets inside the spirit stone ore veins.

——After all, their mining of raw ore is not even as fast as the ‘flesh mushroom’ to convert it into raw ore.

Inside the spirit stone vein.

After observing for a long time, Su Xing carefully switched back to normal state.

After confirming that there was no danger inside the ore veins, but the air was a little thin, Su Xing gradually became relieved and bold.

He patted the storage bag on his waist, took out a dagger, attached his spiritual power to the surface of the dagger, and carefully cut off a 'fruit mushroom'.

After observing several "flesh and blood mushrooms" in different growth periods, Su Xing found:

Once these "flesh and blood mushrooms" leave the human body, they will immediately stop growing and maintain their current state...

Therefore, these mushrooms can be taken away and stored for a long time.

In the field of refining life medicines, Su Xing is considered half an expert.

The formula of life span medicine contains a small amount of protein.

When Su Xing first refined his life span, he used beef instead of these protein components.

Afterwards, he tried chicken, fish, pork and other alternatives one after another, and found that the effects were basically the same.

In short, no matter what material Su Xing adds to replace it, it will never achieve the effect of the medicine like the Heavenly Court...

——The life span medicine refined by the Heavenly Court can be swallowed directly by mortals without any side effects.

However, the pills refined by Su Xing will mutate mortals.

This must be because he did not find a suitable protein replacement.

so....

Looking at the 'Flesh and Blood Mushroom' he cut, Su Xing instantly had a bold idea:

The 'Flesh and Blood Mushroom' is produced from human flesh and is still considered a protein component before it is completely converted into the spirit stone ore.

If you add these mushrooms to the raw materials of the life span medicine and replace chicken, duck, fish and beef, can you make up for the defects in the life span medicine?

Is this how people in Heaven do when they refine life span medicine?

If feasible, Su Xing's life span medicine will be able to be sold in large quantities to mortals and collect more 'black silk threads'.
