In the depths of the bottomless Yang World Underworld, heaven and earth seem to exist in this space, surrounded by billowing black mist, and the yin power gushing out from the depths of the netherworld pool is like thick smoke, surging upward.

In a way that is difficult to see with the naked eye, it gradually fills this space.

However, this space is not pitch black, dull darkness. Instead, the space emits a faint glow, forming a gray color.

In the depths of this sunny world, this gray is particularly eye-catching.

It is the color of the yin force, representing the most yin and cold tones, like black smoke rising from the depths of the netherworld pool, the gray permeates the space, forming a substance like a thick cloud, covering the upper space tightly.

The Yang World Difu is essentially the condensation of the surging Yin Power gathered in the Netherworld Pool in the depths of the earth, and as time goes on, the Yin Power continues to transform this piece of heaven and earth, evolving step by step towards the world that accommodates the broken Yin Soul.

Undoubtedly, this kind of transformation is a bit of an unexpected surprise, Situ Yi originally founded the Senluo Palace, the purpose is very simple, it is to create a place for Situ Bao to settle down.

However, step by step, as Situ Yi's realm and strength continued to leap forward, his perception of the Yin and Yang Dao became more profound, and when he opened up the Yang World Underworld, Emperor Senluo was divided into ten, cast ten halls, and turned into ten halls Yan Jun, in charge of all the Yin Soul remnants who entered the Yang World Underworld.

Because of the close connection between the Yangshi Difu and the Yama Gate, as the territory influenced by the Yama Gate became larger and larger, and the population under its control increased, the number of dead Yin Soul Ghosts and ghosts collected by the Yang World Difu increased several times or more. As a result, the concentration of the yin power contained in the Yang World Difu continues to rise, and the strength is also skyrocketing.

Netherworld pool. It was a complete accident.

Perhaps it is related to Situ Yi's identity as the lord of the Yin and Yang Realm, or the establishment of the Yang World Difu, which makes the core rules of heaven and earth recognized, and under the Ten Halls of Yan Jun, bottomless abysses have been opened.

In order to grasp the information of the Netherworld Pool, Situ Yi also personally investigated.

Unfathomable abyss. The deeper you go, the darker it becomes, and the distance you can see is not enough for tens of meters. Therefore, Situ Yi mobilized his own will, together with the power of the Yang World Difu, and probed downward, and the result was like entering a place shrouded in mist, and all the gray mist was surging in all directions, endless, and completely endless.

And. At the end of the will probe, Situ Yi had a strong directness, and in the deeper depths of the Netherworld Pool, there seemed to be a terrifying and incomparably terrifying force.

Faintly aware that if he stubbornly penetrates deep and provokes that terrifying force, he may suffer a catastrophe in an instant.

That power is very pure. It is very thick and heavier than the earth. It's a hundred, a thousand times more powerful, Situ Yi doesn't even have the words to describe that kind of power.

Later, Situ Yi speculated, and felt that the end of the Yin Realm Pool, which was constantly spewing out Yin power, was probably one of the powers of the core rules of this heaven and earth. It's cloudy and cold!

Although he was protected by the Yin and Yang Dao, and single-handedly founded the Yang World Difu, he has a very strong immunity to the Yin power, and ordinary Yin power can't hurt him at all, but facing the end of the Netherworld Pool. To the power of yin and cold, Situ Yi still didn't dare to try.

He felt that if he entered recklessly without the recognition of that source yin force, the ending would definitely be very tragic.

Although it is not clear where the power of the Netherworld Pool comes from, the existence of the Netherworld Pool, which continuously sprays gray fog outward, has brought very strong basic support to the Yangshi Difu.

Many of the souls left behind after death cannot be exposed to heaven and earth because they have not made the journey, so once the body dies, the souls will directly collapse, and even the manifestation cannot be achieved.

This is because most mortals are unable to cultivate, or only exercise their bodies, and have not been exposed to spiritual and mental training, and their souls are still very weak, like broken glass, which may be shattered by a random blow.

These people occupy a large part of the population base, and these scattered souls, under the operation and mobilization of heaven and earth, are transformed into the original power and return to heaven and earth.

This part of the soul, the Yang World Difu is naturally powerless, and it can't even manifest itself, let alone capture it.

The soul that has been collected by the Yang World Difu is called the 'Yin Soul' in terms of terminology.

He means that the spirit, or will, has been exercised for a considerable period of time, forcing the soul to be strengthened and able to remain in the air for a period of time after the death of the body. Because the body dies, the soul is separated from the body and becomes a different way of being.

Hence the name 'Shade'.

Just looking at the name, as the name suggests, the yin soul is an individual built entirely by the yin power, and can be among some places with strong yin energy, such as tombs, broken temples, and some areas where the scene cannot be illuminated by the sun, in short, as long as the yang power is isolated, it is the paradise of the yin soul.

Compared with the previous life, Situ Yi caught ghosts and refined the raw materials, this world that advocates Xuanmen Taoism, such a method of gods and ghosts, is naturally like a fish in water, and at the same time, because of the chaos of heaven and earth, the Yang World Difu swept away the ghosts after death within the control of the Yang World, and the amount collected was very amazing.

And because of the rampant Xuanmen Taoism, it has also created more powerful soul existences, compared to the previous life, Xuanmen belongs to the hidden world sect, separated from the mortal world, and rarely has a relationship with ordinary people. And in this world, the Xuanmen Dao Technique has become the theme, many people study and study, and the various Xuanmen Dao techniques that have been passed down are also chaotic, so the collection of Yin Souls, both in quantity and quality, greatly surpasses the previous life.

After converging into the underworld, under the nourishment of the Yin Power that continuously erupted from the Netherworld Pool, the Yin Soul rapidly improved and grew, and many Yin Souls of excellent quality stood out from them, and a very few powerful Yin Souls have evolved towards the level of ghost knights.

After leaving the Yangshi Difu for a while, all the things that happened here, the changes in the Yangshi Difu, were all under control, and one of the doppelgangers, the Yama Emperor, sat here, dealing with everything, Situ Yi did not need to waste energy, and after seeing it at a glance, he reined in his will and was ready to focus on the big things that might happen next.

From the preoccupied form and the solemn expression in his eyes, it can be seen that this matter is particularly important to him, and he must not be sloppy! )
