The Eight Thousand Miles of Fire Mountain Range, in the ancient forbidden land of Tianyao Mountain, is an extremely special and extremely dangerous area.

Before he stepped into this area, the surroundings began to be filled with terrifying heat, fire and flame power.

Strange to say, although the temperature in this area is surprisingly high, the vegetation is unusually dense, and there are many insects and beasts.

Everywhere you look, you can see some crimson flame trees, strange grasses.

The sky was littered with small insects like flames, and birds were flying.

Some extremely rare elixirs, which have even been extinct in the outside world for an unknown number of thousands of years, can be found everywhere here.

There are also a lot of people who come here to explore and look for elixir.

Yang Yi walked all the way inside, and he had already encountered dozens of expedition teams.

He flipped over his palm and took out the messenger jade slip of Lingxi Fairy and others, and sensed it carefully.

Judging from the information fed back on the transmission jade slip, the three of Lingxi Fairy, Wuchenzi and Wumizi are in this area.

When Yang Yi sensed the three of them from the Lingxi Fairy, the three of them also sensed Yang Yi's appearance.

It didn't take long for the Lingxi Fairy's messenger jade to be sent simply.

"Yang Yi, where are you now?"

In the jade slip, the voice of the Lingxi Fairy was full of surprise.

Yang Yi groaned for a moment and sent his location to the Lingxi Fairy.

A few quarters of an hour later, the Lingxi Fairy, Wuchenzi and Wumizi rushed over from the depths of the Huoyan Mountain Range.

After meeting, the Lingxi Fairy and the other three couldn't help but complain for a while.

"You kid, I really don't know what the hell you're up to, didn't you say you were going to act together? Why did you suddenly disappear?"

"I had an accident at the time, and I didn't have time to inform you. ”

Yang Yi casually explained to the three of them, and asked them about their movements during this time.

From the mouth of the Lingxi Fairy, Yang Yi learned that at the beginning, the three of them were on the side of the Ten Thousand Demon Valley, and they really looked for him for a while, but unfortunately they didn't find anything.

After going deep into the Valley of Ten Thousand Demons for a while, they suddenly discovered that in the depths of the Valley of Ten Thousand Demons, a large number of Heavenly Clans had appeared, and some powerful demons had also appeared.

The three of them didn't dare to go any further, and they learned from the messenger Yujian that Yang Yi was not in danger, so they withdrew from the Valley of Ten Thousand Demons and decided to come here for the time being, waiting for Yang Yi to come over and join them.

Along the way, the three of them broke into several forbidden places, and really got a lot of good elixirs.

Even the three of them have each obtained some adventure inheritance.

Especially the Lingxi Fairy, who was unexpectedly recognized by a fairy treasure flying sword, and successfully refined it.

Now the strength of the three of them is the most in Lingxi Fairy.

"Lingxi Fairy, have you gained anything here?"

Yang Yi's gaze turned to the Lingxi Fairy.

Since they had come here a long time ago, and they had been looking around here for a while, they should have a general understanding of this Flame Mountain Range.

Fairy Lingxi shook her head and said with a solemn face: "There is nothing to gain." It's too weird to explore. ”

Wuchenzi also said: "Yes, according to Poor Dao's observation, this Flame Mountain Range should be an extremely ancient and powerful Heaven and Earth Sealing Field. Not to mention the Heavenly Star Realm, I'm afraid that even the powerhouses of the God Realm are helpless when they come here. ”

Wuchenzi's words couldn't help but make Yang Yi stunned.

Yang Yi knew Wuchenzi's ability in the forbidden formation.

Even he said such a thing, which shows the special feature of the formation prohibition here.

"I think there are so many people exploring here, could it be that no one else can do it?"

All three shook their heads with wry smiles.

"During this time, we have seen all kinds of methods to break the ban, and none of them are useful. Even some Celestial Clans, who have used artifacts, are just as useless. Wuchenzi said in a deep voice.

Yang Yi closed his eyes and thought about it, and in his mind, he recalled the contents of the jade slip that he had obtained from the Lingxi Fairy.

Then, he carefully thought about all the deeds related to Emperor Yan in his mind.

Gradually, some trivial information that had been ignored was slowly connected together.

A memory event that should not have been remembered, or rather, was not awakened, suddenly appeared out of thin air.

He remembered what kind of place these eight thousand miles of flaming mountains were!

This is the "Nine Yang Sealing Demon Mountain" used by Emperor Yan to suppress an ancient demon!

This big array is Emperor Yan's best "Nine Yang Sealing Demon Array".

Not to mention Wuchenzi and those Heavenly Clans, even the real ancient gods are here, and they are also helpless against this big array.

At the bottom of the "Jiuyang Sealing Demon Mountain", there was a great demon that had reached the Divine Martial Realm with cultivation.

Back then, the demon lord of the Nine Shadows Land once led the demon army and invaded the human world.

Under the leadership of the Five Emperors, the Terrans have fought dozens of fierce battles with them.

And at the beginning, under the command of that demon lord, there were five demon god generals, the most fierce and arrogant.

Their strength is roughly equivalent to that of the Five Emperors.

The demon god who led the army to invade the area ruled by Emperor Yan was a great demon named Yan Guang.

This demon is also known as the Light Demon, a strange demon god who can control the power of Xuanguang, and is also skilled in the art of illusion and confusion.

There are quite a few strong people of the human race who have broken in his hands.

Emperor Yan fought fiercely with this Yama Demon God for several months, and finally had no choice but to use an extremely special method to introduce this Yama Light into the Void Realm, and then disappeared.

Emperor Yan never reappeared, and neither did the Yama Demon God.

At that time, there was a rumor that Emperor Yan would not let Yan Guang invade the Terrans of the Shenwu Realm again, and he would die together in the Void Realm.

At the beginning, there were also human powerhouses who entered the Void Realm through the void passage in the place where they disappeared, but they found nothing.

Now it seems that Emperor Yan did not die at that time, but together with Yan Guang, in the Void Passage, he was swept into the turbulence and landed in the forbidden land of this Heavenly Medicine Mountain.

Moreover, Emperor Yan also successfully arranged the "Nine Yang Sealing Demon Array" and sealed the Yan Guang in this array.

Of course, all this is an inference based on the records in the jade slip and the synthesis of Xuanyuan Yan's memory.

Whether this is the case or not, you have to enter the "Nine Yang Sealing Demon Array" to know.

While Yang Yi was pondering, the face of the Lingxi Fairy had a look of loss that could not be concealed.

During this time, she has been wandering around this flaming mountain range.

However, after searching the area she could explore, she couldn't find any news related to Songhecao.

Moreover, the environment here is like this, and it doesn't look like a place where the eight-grade elixir like the pine crane grass can be grown at all.

"Lingxi Fairy, why are you sullen?"

Yang Yi retracted his thoughts, raised his eyes and saw the sad face of the Lingxi Fairy, and couldn't help but ask.

"Nothing. I'm just thinking about the pine crane grass, you look at the situation here, where is the place where the elixir of the pine crane grass can grow?"

The Lingxi Fairy smiled bitterly and shook her head.

Yang Yi smiled slightly and said, "That's not necessarily. This place is an ancient sealing field. The environment of the sealing field is different from other places, and any kind of elixir may grow. ”

"Oh, what do you mean by that?" said the Lingxi Fairy with a moving expression.

"I believe that the dustless Taoist should also be very clear about this. Yang Yi smiled and looked at Wuchenzi.

Wuchenzi brushed his beard and said: "Yes, Poor Dao has carefully observed, it is very likely that this is the Jiuyang Sealing Field." In the environment of the Jiuyang Sealing Field, don't look at the high temperature and scary, but in fact, it is the best place for all pure yang elixirs to grow. ”
