Yun Feng took out the necromantic dungeon map, and analyzed this dungeon map according to the actual situation, for example, in those places in the dungeon, there are hidden weapons, those places have corpses, and those places have formation enchantments. After two hours of research, the six finally set off. Their main route was naturally to the haunt of the corpses.

The Necromantic Dungeon is under the ground of the Corpse Refining Palace, that is, the lowest level of the Necromantic Ice Palace, and the entrance is under a dark prohibition that Dieyou accidentally discovered, Yun Feng used the technique of flicking his fingers to break the dark prohibition very lightly. And Bat Xiaotian himself cultivates the dark technique, and he can enter directly without breaking this prohibition.

Entering the Necromantic Underground Palace, the Necromantic Dungeon was dark, and the six of them walked in a narrow tunnel, which was deep and bottomless. Of the six people, only the butterfly demon power is the lowest, and they can't open the knot qi shield, and in order to prevent the invasion of zombies, Yun Feng and the others have opened the knot qi shield, the fire knot gas shield, which can shine around with red light, and Wolf Yue's knot qi shield belongs to the golden nature, which is naturally glowing with golden light.

The walls of the tunnel are carved and cast from thousands of years of cold ice, Yun Feng feels a little cold even if he has a fire technique, Yun Feng looks around, and tests the cold ice of these walls with his hands, it turns out that the cold ice of this wall is more than a million years old, and it is extremely cold. Dieyou held the dungeon map in his hand and walked side by side with Yun Feng, the two were discussing the dungeon, and the four of them were walking behind, and there were a lot of words between the four.

Yun Feng and the others traveled according to the description on the dungeon map, but they really didn't encounter any obstacles, which made Yun Feng annoyed, he had an epiphany a month ago, but he wasted a month. This underground palace is like a labyrinth, six people go in together, nine turns and eighteen turns in this necromantic ice palace, Yun Feng secretly scolded the design of this ice and fire demon god in his heart, and actually set up his tomb into a labyrinth, it seems that stealing the cemetery of the ice and fire demon god is really not an easy thing. However, Yun Feng was fortunate to have a dungeon map.

Yun Feng was also a little worried about Bat Xiaotian, Bat Xiaotian was hot for a while, he entered here before them, and now he must have gotten lost in the underground palace, but it is a pity that he didn't persuade Bat Xiaotian at the beginning, Yun Feng couldn't help but shake his head when he thought of it, in fact, it is a trivial matter to get lost in it, if he encounters a hidden weapon trap, it will not be a good thing, it will be seriously injured or dead.

According to the description of the underground palace, the four of them walked for about half a day. Finally came to an open place, where there was a fire, which made Yun Feng and the others surprised.

"Kaederou, look. Yan Qing'er pointed ahead, her face was full of joy, Yan Qing'er, who had always been curious and playful, saw the scene ahead, and ran towards the front happily.

Yun Feng swept his eyes, only to see that there were ice pools, pavilions, pavilions in front of him, and the most eye-catching thing was that the ice pool was full of lotus flowers with transparent flames, Yun Feng secretly thought: "Is it possible, these are the legendary flame red lotus." ”

The Flame Red Lotus can only live in a dark environment, and at this time it is blooming one by one, Yan Qing'er is curious to count these Flame Red Lotus, and after a while, she finally counted one hundred and thirty-seven blooming ones, and there are about a thousand unopened buds, scattered in this thirty acres of ice pool.

"Flame Red Lotus!" Yun Feng shook his head, sighed at the beauty and rarity of the Flame Red Lotus, and said, "I didn't expect that we would dig up a treasure here, and if we find the Flame Red Lotus, my sister's illness will be cured, but I don't know how Brother Bat is doing now." ”

"Hehe, pick one first, and see. Yan Qing'er was full of curiosity.

The flames of the red lotus are constantly rising in the hearts of the red lotus, shining on the four fields, and the scene is extremely beautiful.

Yan Qing'er spread her wings and flew over the ice pool, leaned over to pick one, and held it in her hand, very curious: "The Flame Red Lotus, the whole body is swallowing flames, so how can it be used for medicine!"

Dieyou said: "Since it can be used in medicine, it naturally has a method to enter medicine." ”

"Is it possible to become Sister Butterfly, there is a way to use the flaming red lotus into medicine. Yan Qing'er asked again.

Dieyou smiled silently, it seemed that using the Flame Red Lotus into medicine was not a difficult task for her at all.

According to the description on the dungeon map, after walking through the winding corridor of the ice pool, you can enter the Necromantic Ice Palace of the Ice and Fire Demon God, but now Yun Feng is a little disappointed, because the path in front of him is all blocked by ice.

However, the ice is thorough, and you can see the situation inside through the cold ice of millions of years, and this ice is indeed a real tomb, but Yun Feng also sensed that something was wrong, that is, inside the tomb, there was actually a very terrifying energy body.

"Sister Dieyou, there seems to be a terrifying energy body fluttering in this tomb!" Yun Feng's divine sense swept through the ice.

"It's the primordial god!" Yan Qing'er's divine sense also penetrated into it.

"What??" Yun Feng said in surprise.

"It's unlikely! It's been tens of thousands of years, if the primordial god can't find a physical body within a hundred years, the primordial god's own aura will gradually dissipate until it perishes. Presumably this has gone through tens of thousands of years, even if the primordial god of ice and fire is powerful, his primordial god should have been destroyed a long time ago. Que Xuan said.

"That's right, this energy body doesn't seem to be powerful, and if it's a primordial god, it's unlikely. What is that?" Dieyou sighed to herself.

"Just go in and take a look!" Since he was full of curiosity, Yun Feng was already a little impulsive!

However, the tomb was frozen in ice, and it was really difficult to get in, Yun Feng and Musk Lianhua, Yan Qing'er, and Que Xuan glanced at each other.

The three of them immediately used the most powerful formation, the Yin Yang Demon Fire Vertical Formation, to break the ice and try to open the passage of the tomb.

As soon as the formation was placed, thirty-six fire dragons were freed out of the palms of the four people, and they continued to impact and slam on the ice, but they had no effect, which made Yun Feng and the others feel frightened.

"Millions of years of ice, how can it be broken through so hard!?" Dieyou said insightfully.

"There is a record in "Supreme Demon Fire" that the Supreme Demon Fire to the fourth melting iron and gold, can refine thousands of years of pure gold, ten thousand years of ice, everything melts, everything melts, everything melts. When Yun Feng said this, he also remembered that the cage that Yao Frost was trapped in was made of thousand-year-old pure gold, so he couldn't get out.

"What about Feng Lang now?"

"I have now reached the fourth stage of demonic power, and it stands to reason that I have already had an epiphany of this molten iron and gold, but I have tried it a few times before, and I have also tried to use the tips given to me by my aunt to cultivate, but I still find it a little difficult to break through. Yun Feng said.

"It's not just you! I'm not the same! This supreme demon fire is not as easy as I imagined! Haven't I also had an epiphany for half a year, and I still can't do it?"

"Actually, you have indeed tried your best for the epiphany of the supreme demon fire, the fourth rush of the supreme demon fire realm, when you rely on your own epiphany, how can you succeed!?" Dieyou seemed to think of something.

"Sister Dieyou, there must be a way for us to break through to the fourth realm of supreme demon fire. Yun Feng asked eagerly, and thought that at that time, Yao Qizi said that his demon power had reached the stage of demonism, and he would be able to have an epiphany of the fourth level of supreme demon fire, now thinking about this, Yun Feng would only feel that Yao Qizi was really whimsical, how could it be so easy to cultivate demon fire.

"I just thought of something, I can give it a try! Maybe it really won't take long for Kaede Lang to have an epiphany about the fourth rush of the supreme demon fire. After saying that, Dieyou took out a book from the storage bag, and then flipped through it, Dieyou's eyes lit up again, and her face was unusually happy

Yun Feng reached out to pick up the book in Dieyou's hand, but Dieyou gently moved the book behind him, and said with a smile on his face: "Fenglang, this book is mine, I don't want to show it to you now."

Yun Feng naturally knew that Dieyou was joking with himself, and said, "Don't show it!" Yun Feng pounced on Dieyou and said, "I want to see it!"

Yun Feng's strong left arm hugged Dieyou's waist, and one hand went to grab the book, who expected Dieyou to gently put the book into the storage bag, Dieyou laughed, and said: "Fenglang, you can't find it, I have tens of thousands of books in this storage bag." Even if you ask to look for it, you won't be able to find that book in half a year, and you don't know what it is!"

Yun Feng pinched Dieyou's smiling face and said, "Okay, stop playing, take it out!

Yun Feng deliberately looked at Dieyou with a pitiful look, and at this time, Dieyou said softly: "Okay! If I help you break through to the fourth level of supreme demon fire, then how can you repay me?"

Yun Feng whispered in Dieyou's ear: "It's a big deal to get out of this necromantic dungeon, I'll let you live happily for a few nights."

Dieyou pushed Yun Feng away and said, "What a hooligan, a complete hooligan, I will ignore you." ”

Dieyou put the book into Yun Feng's hand, and said, "Study it slowly!"

An ancient book that looks a little worn out and yellowed, according to the marks on the book, it can be seen that this book was taken out of the Tibetan Scripture Palace of the Necromantic Ice Palace, and named "Materia Medica".

"The Heart Sutra of Materia Medica!?"

Yan Qing'er, Musk Lihua, and Que Xuan also leaned over to look.

Die Yu said: "This book, but it was written by the Ice and Fire Demon God himself, and the Ice and Fire Demon God himself is more greedy, so his work is inevitably a little obscene, but compared to the book "Yin and Yang Combined Vertical Formation" he wrote, his book is much better." ”

Yun Feng said: "It's hard to make this book, it's also about the harmony of yin and yang." ”

"Feng Lang! Don't think too much about it! This "Materia Medica Heart Sutra" is also about the wonderful method of condensing aura and sprinting veins, but the precious medicinal materials used in it are not something that ordinary people can afford, even if you are a prince and a son of a rich family, you may not be able to cultivate this Herbal Heart Sutra. Because the medicinal herbs here are not what you can find. "Butterfly Whisper.

Yun Feng roughly flipped through this book, and the medicinal materials recorded on the book were 'day and night grass', 'endless * roots', 'mandarin duck wings in the south and north of the world', 'warm in winter and cool in summer, ripe fruit in autumn and spring"

"What is this?" Yun Feng has been reading books since he was a child, but he has never heard of these things.

"Look through it again"

"Flame Red Lotus! isn't it!" Yun Feng actually found a record about the Flame Red Lotus in the book.

Yun Feng said to himself: "It's so good, it's wonderful, hehe"

"That's right, what is recorded in the book is the Flame Red Lotus, most of these herbs recorded in this book have been extinct, so the world has never known about it, but the Flame Red Lotus is a legend, so it is known by the world, because the cultivation of the Fire and Fire Demon God's fire exercises, most of them use this kind of fire red lotus supply. So, now it's not only Brother Yunfeng who is lucky, but also the three sisters and sisters who are also lucky. Who told you to all be people who practice fire-based exercises?" Dieyou said.

"Who said that these herbs are all extinct!" Yan Qing'er suddenly looked arrogant as she spoke, attracting all her eyes.

"I forgot, Sister Qing'er is the daughter of the number one merchant in the demon world, and her family is very rich, it is said that Sister Qing'er's childhood cultivation place is all extinct medicinal materials built with upper-grade spirit stones, which must be found in Huoyan Villa. "Musk Blossom Road.

It is said that Yan Qing'er reached the fourth stage of the charm at a young age, and the reason is said to be that Yan Qing'er has cultivated in the field built by the upper-level spirit stone since she was a child. It is true that there are frozen bones on the stinky road of Zhumen's wine and meat, and only Huoyan Villa can be so extravagant, so it is not surprising that Huoyan Villa has this kind of extinct medicinal materials.
