I don't know if the alley they picked was relatively winding, or the alleyway leading to the fire area was so long, and they didn't see an exit after walking for most of the day.

Feeling the strange gazes that Huo Yan'er cast from time to time, Wu Yu thought for a while and asked out loud, "What are the six dark envoys you just mentioned?" ”

"You don't know that?" Huo Yan'er was surprised, and immediately patted her head: "I almost forgot, you don't even know the dark domain." ”

"The six dark envoys are Destruction, Extinction, Dark Domain, Abyss, Devouring, and Confusion, they have no specific names, and these names are also known by the Elemental Envoys of the past generations in the course of their battles, and then passed down from generation to generation."

Wu Yu said: "I heard that the Dark Envoy is actually a creature controlled by the Dark Divider, does this mean that as long as the Dark Origin is not destroyed, the Dark Envoy will not die?" ”

Huo Yan'er's expression remained unchanged, and her tone was quite helpless: "How can you ask some questions that cannot be verified, I have also heard of this statement you mentioned, according to the traceable history, as well as the opinions of the elders, this statement may be the closest to the actual situation." ”

"Also, I've heard a rumor."

The corners of Huo Yan'er's mouth were slightly hooked: "It is said that the Dark Domain was once killed by several elemental envoys, and after a few decades, he reappeared, and it seems that he forgot that he had been killed. ”

Wu Yu pondered: "If this rumor is true, then the essence of the dark envoy is likely to be the consciousness generated by the spirit of the dark source. ”

"The Dark Angel is killed, which means that the corresponding consciousness has been wiped out, which may also explain the rumored amnesia after the resurrection of the Dark Realm."

Speaking of this, Wu Hao pondered for a moment, and suddenly asked again, "How much do you know about the ability to confuse confusion?" ”

Huo Yan'er's eyes flickered slightly: "Why did you suddenly ask about this." ”

Wu Yu still looked contemplative: "I have always doubted whether the essence of consciousness will be a kind of spiritual power, and the speculation that spiritual energy produces consciousness makes me feel that my previous doubts are not without the possibility of existence. ”

"I heard that the main ability of confusion is related to mental power, so I'm curious."

Spiritual power is a field that human beings have not been able to figure out so far, and the curiosity he is showing at the moment is very reasonable.

"You're a bold guess."

Huo Yan'er smiled: "It's a pity that the specific information about the Dark Envoy requires a high level of authority and contribution to be known, don't look at me as a personal disciple, the authority is very low before the king level, where would you know so much." ”

Speaking of this, she suddenly asked, "Then again, why are you so interested in spiritual power." ”

From ancient times to the present, most of those who have studied spiritual power have reached the ceiling of their own talent on the Xuan Dao, and they have to find another way in the direction of spiritual power, and few normal people will really be interested in spiritual power.

Wu Hao's face remained unchanged, and he gave a very simple reason: "When a normal mystic casts a magic skill, there will be more or less spiritual power fluctuations, but I don't. ”

"You're saying you're not normal?"

Huo Yan'er clearly remembered that she had been choked by Wu Yu a few times before, she originally wanted to make a joke and choke back, but she didn't expect Wu Yu to nod very seriously.

"I'm not normal."

Huo Yan'er: "......"

It took a long time for her to clear her thoughts: "You mean you don't have mental strength?" ”

Wu Yu shook his head: "I should have spiritual power, I can cast magic skills, and I have also overdrawn mental power, the only problem is that I can't sense the existence of spiritual power in myself, do you know why?" ”

Huo Yan'er frowned, and after some hard thought and meditation, she suddenly had an idea: "I have thought of a good way, maybe we can start with the storage place of spiritual power." ”

Wu Yu's eyes lit up: "Do you know where the spiritual power is stored?" ”

"Yes."

Huo Yan'er's pupils glowed with a terrifying light, and her right hand was placed in the shape of a claw: "I heard that spiritual power is stored in the brain, why don't I try it for you?" ”

Wu Yu didn't seem to hear what she meant, and said calmly: "There was an emperor who tried it with spiritual pressure before, but it didn't have any effect on me, so forget about your cultivation." ”

Huo Yan'er smiled and withdrew her right hand: "It's a pity that I don't know much about spiritual power, otherwise I can help you think of a way." ”

Wu Yu wiped the few fine beads of sweat oozing from his forehead: "It's so hot, is the fire domain coming?" ”

"I haven't walked this passage before, but it looks like it's right ahead." Huo Yan'er pointed to the faintly flickering crimson light at the end of the alleyway, which seemed to be a burning flame.

……

Located deep underground, the Molten Fire Domain is composed of multiple rings of decreasing diameter superimposed on each other, and the overall structure is somewhat similar to those sunken plazas in the county town, but the two are definitely not comparable in scale - a rough estimate of the entire fire field is definitely more than ten miles in diameter.

For the entire Yongyan Mountain, this size may not be very large, but in this closed underground world, under the background of the rolling heat wave and the crimson and almost black firelight, this scene is enough to shock everyone who comes.

The ubiquitous fire element brought an extremely high temperature, and even if Wu Yu opened the protective Xuan Qi, beads of sweat still began to appear on his forehead.

On the other hand, Huo Yan'er showed no signs of sweating at all, which made him sigh that the Fire Domain was worthy of being a holy place for fire cultivation.

When she was in the alleyway, Huo Yan'er introduced to Wu Yu that there are five layers in the fire domain, the first four layers are considered peripheral areas, the fifth layer is a lava field full of magma, and the core area is located in the center of the lava field.

Wu Yu's location was at the top of the Fire Domain, which was not an accident, as all the entrances to the Fire Domain led to the first layer.

Of course, there were originally passages to the second floor, and even the third and fourth floors, but the exits were changed.

The difference between the layers of the Fire Domain was more than 100 zhang, so from their current perspective, they could only see the heat wave and fire light surging in the center of the Fire Domain, and they could not see the lava field and the core area at all, unless they walked to the edge of this layer, and Wu Yu and they were doing the same.

The ground was covered with a layer of dark red ash, which was the mark of repeated volcanic tremors, and it was a step by step to walk on it.

Originally, for safety reasons, Wu Yu planned to take a step to clean up a footprint, but his time-consuming and laborious actions quickly attracted ridicule from Huo Yan'er.

Not to mention how many entrances and exits there are in the Fire Domain, after the sect strengthened its vigilance, there are few people who are qualified to enter the Fire Domain at this time, and more importantly, the volcanic tremors that may occur at any time will wipe out the traces left by all the arrivals in an instant.
