After Su Heng finished speaking, he was in a state of silence, he was a little uncomfortable, probably recalling too much of the past.

Wang Yu didn't speak, but was thinking about the situation explained by Su Heng, the two of them didn't open their mouths in the illusion, they sat like this, and time passed unconsciously.

Suddenly, Wang Yu raised his head, and there seemed to be a glint in his eyes.

"I've found a problem." Wang Yu said slowly.

"If the soul power reaches the limit and cannot be improved, then, can the ghost fire in this world increase the level of soul power in disguise."

After hearing Wang Yu's question, Su Heng didn't seem surprised, he adjusted his posture, breathed a sigh of relief, slowly leaned back, leaned back in the chair, closed his eyes, and replied:

"Yes, the Ghost Fire can improve the strength of the holder's soul from another angle, which is also a direction at that time, but it's just ......" Su Heng said here, pausing.

"It's just that the strength of the ghost fire that I know now is already the highest in the past hundred years, golden, equivalent to the ninth level of the spiritual power, but no one can reach it."

Su Heng sighed.

"Since you can explore the golden ghost fire, why is there no one in the Northland Mansion to use it?" Wang Yu then asked.

"Because this only appeared in ancient books, in about 600 years of history, when the north and the south cooperated for the first time, the same way, the same creative process, the same failure, but those failures can be contained and eliminated, because only one person did the golden ghost fire at that time, and no matter how hard the people of Beidi Province tried in the future, no matter how hard they tried, no matter how much they tried to find a way, no one would reach that level anymore."

So, after 370 years, even if you create a "god" again, if you fail, there is no way to contain it and stop him?

Wang Yu already had some answers in his heart.

Because of the loss of the information on the level of the ghost fire, it caused a fault, and many people were stuck in the previous level of the golden ghost fire, blue, which led to the inability to improve its soul power, and the spirit power in the competition for the holder's consciousness, fell into a disadvantage, although it was evenly divided at the beginning, but the spirit power is active, and it can continue to devour the holder to enhance itself.

In this case, there is only one possibility, that is, the level of soul power far exceeds the level of spiritual power, and the wielder can control his self-consciousness.

"I shouldn't have a problem for the time being, what about you, do you have anything else?"

After Wang Yu figured everything out, he didn't think about it anymore, because thinking too much would only make him more tired, it was better to put it in the deepest part of his heart and have the opportunity to touch that realm, after all, he was only a first-level spiritual power user in terms of strength.

But according to the level of the ghost fire, the primary ghost fire (green) is also equivalent to a fifth-level spiritual power user.

"I'm fine, just come back to see you, I'll tell some relevant information to those in power in the Northland Mansion by the way, maybe I'll get the news early in the morning."

Su Heng squinted his eyes as he spoke, "Are you going out, or are you just staying in this illusion until dawn?" ”

Seeing Su Heng's leisure and elegance, Wang Yu couldn't help but sigh in his heart, if he and Su Heng swapped places, he would definitely not be able to do Su Heng so leisurely.

Wang Yu stood up from the chair, moved his body, and replied with a slightly helpless expression:

"No, after listening to what you said, I don't want to sleep anymore, I'll go out, my teacher brought me some books, I'll go out and have a look, by the way, when can I go to Beidi Mansion to have a look."

"Huh? Are you in such a hurry? As long as you get the temporary portal, you can use the token I gave you at any time. ”

When he said this, Su Heng didn't even raise his eyelids, as if what he said had nothing to do with him, it seemed that recalling some things was a disguised relief for him.

Temporary portals, this Wang Yu once heard his senior brother mention, some places have a harsh environment, the transmission of soul power is more strict, because the material of the portal in the city is relatively ordinary, generally can not go to some special places, so the underworld will also provide some temporary portals, the material of these portals is mostly made of a white-gray soul melting stone, which can absorb soul power well, and can also accurately point the channel to the other party in a specific environment.

"Okay, then you get me out, I'll read the book." Wang Yu turned his back, looked at the door of the house, and was ready.

"Yes, we'll see you next time."

Su Heng smiled softly, raised his right hand that was tickling under his armpit, and under Wang Yu's gaze, a white light emanated from his palm, illuminating everything in the room.

……

Call~

In the room, Wang Yu opened his eyes, got up a little tired, opened the window, and looked at the sky, today is the full moon, and the moon is setting towards the east.

"It looks like it's not far from dawn."

After looking at himself, he felt that his state was okay, and he was not as tired as he imagined, Wang Yu took out a book wrapped in cloth from the ring, which was handed down by his teacher's teacher, and if he calculated carefully, it was estimated that it would be almost a hundred years ago.

Putting things on the table, carefully opening the outer packaging, two somewhat yellowed books appeared in front of Wang Yu, one was thicker, about half a fist high, with a record of the experience of using the ghost fire written on it, and the other one was relatively thin, only about half of the previous one, with the rank and promotion of the ghost fire written on it.

"Promotion?" Wang Yu's heart moved, and he hurriedly opened the book about promotion first.

As expected, the promotion conditions for each level of the ghost fire were recorded above, but Wang Yu's focus was on the last, and the promotion conditions of the golden ghost fire turned to the last page, only to see that the description of the golden ghost fire above was one sentence: "The promotion conditions are unknown and have been lost." ”

"It should have been expected." Wang Yu closed the book with a somewhat disappointed expression.

After regrouping his mood, he sat down in his chair when he was ready, opened the Ghost Fire usage record, and began to read.

After just reading it for a few minutes, Wang Yu felt that this book was very suitable for him, and it was also very suitable for those who were new to ghost fire.

As mentioned above, the use of ghost fire is not limited to fire, it can be in any form, it can be sharp, it can also be hard, and even after proficiency, it can control the temperature of ghost fire and reduce the temperature to a controllable point.

"After a long period of exploration, the form of ghost fire is roughly divided into the following grades, and the main grades are: ordinary (green), elementary (purple), intermediate (dark red), advanced (blue), excellent (golden), and Tongshen (black)."

When he saw this, Wang Yu's secret heart was shocked, but he didn't expect that there was a level behind the gold, and judging from the description, it completely corresponded to the tenth level of the spiritual power.

"The user of the ghost fire, after being proficient, can use any part to stimulate the ghost fire, the premise is that it needs to be practiced, otherwise the failure rate is very high, the ghost fire can be completely separated from a part of the soul after mastering it, and the doppelganger and the body communicate by the soul power, and the ghost fire can be universally ......"

Just seeing the basic content, Wang Yu felt that his understanding of the ghost fire had improved to a level, and he immediately concentrated and watched until the first rays of sunlight outside, through the branches, shone through the gaps on his desk and body.

Wang Yu, who felt a trace of warmth, got up, moved his muscles and bones, washed, and finally picked up the long coat on the hanger, came to the public office room, and just went out, he unexpectedly saw the captain sitting on a high-backed chair looking at a letter.

After a period of wake-up service by the captain, everyone gathered here.

"Let's go to the next city today and draw lots."

Looking at the sleepy team members, Zhou Fei seemed to have gotten used to it, he took out a stick holder from the horizontal bar under the table, and stuffed some wooden sticks in it, not much, but there were seven or eight, and the side of the wooden stick with the content was deliberately placed downward.

"There are 5 of us now, according to the regulations, who gets up late today, who will smoke, Huayun, you come."

Hua Yun, whose dark circles had not completely subsided, took one from the stick holder at random and placed it on the table, with three words written on the top of the wooden stick, Eternal Night City.

"Wow~" Hou Meng exclaimed slightly.

After Zhou Fei saw that it was Eternal Night City, his eyes also trembled a little, but in the end he still announced the result:

"Let's go, go to the Eternal Night City, Ah Cheng, Ah Cheng!"

Zhao Cheng was in a daze, and was suddenly woken up by Zhou Fei's voice. He looked nervously at everyone.

"What are you doing, what's the matter, this is ......?"

Hou Meng smiled and patted him on the shoulder, and said with some excitement: "Prepare the temporary portal, let's go underground!" ”

As soon as he heard the word underground, Ah Cheng's originally collapsed shoulders suddenly stood up, and he immediately replied with a hundred times more energy: "No problem, in 5 minutes, let's go underground!" ”

……

In the south, there is a huge deep pit in the northwest direction of the City of Time, the diameter of this pit is about half the size of Time Street, from the entrance of the cave you can see a circle of stairs, the stairs are made of special gray rock, in the center of the surrounding stairs, there are 8 huge quarrying binders, on which hang hemp rope as thick as the waist of adult men, they carry 8 unique elevators invented by the second main city, Luminous City, each elevator can bear hundreds of kilograms, They carry most of the city's transportation to and from the outside world.

Along the stairs and elevators, down the extension of about 200 meters, is the city of eternal night, because of the perennial underground life, almost no sunlight, it is precisely because of this particularity, the southern government attaches great importance to the inclination of resources than other cities, which leads to the development of underground space is absolutely fast, so it is also called the underground paradise in the south.

The city of eternal night is full of power lines swaying in the air, garbage on the ground, and the noise of people.

Inside a building similar to a church, there is a portal that is exactly the same as the ground, and there are four or five sheriffs guarding it, and at this moment, inside the portal, five people of different heights have walked out, they are wearing long clothes, and a silver brooch is hanging on their left chest, and their faces appear in the church calmly.

The sheriff who was the leader only glanced at the brooch, and then no longer did anything to stop it, but took the lead in saluting the five people who came out, and said sincerely:

"Welcome to the City of the Eternal Night!"
