The black boulder looked very solemn and dignified. The surface of the boulder was black, and a faint bright yellow pattern could be seen mixed in it.

The closer they got to the volcano, the heavier the pressure became.

When he flew up to the top of the mountain, he found a hole about five meters in diameter. Grass grew on the sides of the hole, which was dyed in black and yellow.

It grew in the vicinity of the Black Yellow Flame. Even though these small grasses were originally ordinary weeds, they had now become precious medicinal herbs.

Without hesitation, Li Dao jumped down from the tiger's back and entered the cave.

"This place is so weird, could big brother be in danger if he just jumped?"

The Fairy Doctor worriedly asked as she looked at the black shuttle's beast-like entrance.

"Pfft, little girl, you liar, you are simply worrying too much. With master's cultivation, you can go as far as you wish on the Dou Qi continent. How could you encounter any danger?"

The White Tiger sneered. It thought that since it was a Class 8 White Gengjin Tiger, it could only act like a kitten in front of its master. Then its master could only be a Dou Sheng!

Yun Yun did not say much as she followed closely behind Li Dao and jumped down.

"Little White, Big Brother and Big Sister Yun Yun went in. Let's go in as well." The Fairy Doctor grasped the White Tiger's fur. She might not be able to jump down like Li Dao and Yun Yun.

"Coward." The White Tiger was slightly disdainful as it squeezed its way through the hole with great difficulty and entered inside.

Following the entrance of the volcano, the black and yellow stone inside became thicker.

The entrance was not big, and as they walked down, the space became wider, the temperature also gradually increasing.

However, even though the temperature of the mountain was increasing, it was not frightening. Even a Dou Shi could barely withstand it. After all, the Black Yellow Flame was not famous for its high temperature.

It went down more than 5,000 meters, about in the middle of the mountain. The dark red magma pool was like a pool of stagnant water.

In the middle of the magma pool, a unique flame was quietly burning.

The exterior of the flame was a thick black Flame Cloak, and in the middle of the Flame Cloak was a cluster of bright yellow flames.

"This is Xuan Huangyan?"

Yun Yun stood beside Li Dao, looking at the flames within the magma pool and asked.

Li Dao nodded his head. He stepped through the air and approached Black Yellow Flame above the magma pool.

The Fairy Doctor and the White Tiger had also arrived. The man and the tiger were quiet and did not speak. Perhaps it was because they were affected by the Black Yellow Flame and could not be more lively.

As he approached the Black Yellow Flame, Li Dao did not feel any temperature. In fact, even the temperature of ordinary flames was higher than this Black Yellow Flame.

He extended his hand to grab at the Black Yellow Flame but did not encounter any resistance. It seemed that the Heavenly Flame ranked 23 did not have any intelligence.

A Heavenly Flame giving birth to intelligence was a terrifying thing. For example, the Fallen Heart Flame suppressed by the Jia Nan Academy, was not even able to subdue a semi-sage expert like the Hooligan Heavenly Ruler. The 'Bone Chilling Flame' ranked in the top three of the 'Fallen Heart Flame' was actually subdued by Yao Chen, this Dou Zun. This was the difference between a 'Heavenly Flame' and a 'Heavenly Flame' without intelligence.

For example, the Demon Flames of the Pure Lotus and the Nihility Swallowing Flame. The Demon Flames of the Pure Lotus had devoured the Nine Star Dou Sheng and the Nihility God Stage had always been in the Soul Clan.

The Pure Lotus Demon Flame and the Void Swallowing Flame could be said to have completely Awakened; they were no different from greater demons. If they were to cause trouble, most likely only Gu Yuan and the Heavenly Soul Emperor would be able to suppress them. Of course, that was only to suppress them.

Li Dao did not encounter any resistance and directly grabbed onto the Black Yellow Flame. However, the next moment, a change occurred which caused Li Dao to be slightly surprised.

The black and yellow Black Yellow Flames were just a flame that seemed to float lightly on the ground. However, when one held it in their hands, they would realize that it was simply heavier than a mountain.

The veins on Li Dao's forehead were bulging, and even on his arms, they were popping out.

First, he practiced the Golden Buddha Indestructible Body into the Dao, then he practiced the Zhang Tie body and finally fused the Zhang Tie body and the blood nerve into the Blood Buddha Body. Without mentioning anything else, Li Dao's strength could definitely pull up mountains and rivers. But now, he almost couldn't hold up this seemingly light Mystic Yellow Flame. It had to be said, Xuan Huang's name was indeed Xuan Huang.

Black Yellow also refers to one kind of color, as well as the heaven and earth. The profound is the sky and the profound is the yellow, so the Mystical Yellow Flame can be understood as the fire of heaven and earth.

Li Dao's eyes were unhurried. His left hand was struggling to hold back the black and yellow Black Yellow Flames while his right hand was burning with a golden colored, somewhat transparent flame.

As soon as the Blood Gold Flame appeared, the lava in the mountain began to boil. Half of it was like boiling water, while the other half was solidified and extinguished.

Yun Yun took a few steps back. Her body was covered in sweat, and half of her dress was wet. The other half was covered with frost.

The White Tiger was protecting the Fairy Doctor as it looked at the Blood Golden Flame in Li Dao's hand in bewilderment. It cried out in alarm, "Master, what kind of strange fire is on your hand? It feels so terrifying!"

The Fairy Doctor and Yun Yun shook their heads at the same time. They also did not understand the Blood Gold Flame in Li Dao's hand.

The Blood Gold Flame was ignited by the fusion of Li Dao's blood and faith energy. Like the Black Yellow Flame, its temperature wasn't too terrifying. However, after devouring the Bone Chilling Flame, it had fused with the extreme heat and coldness of the Bone Chilling Flame.

Li Dao didn't know how powerful the Blood Golden Flame was. It might be inferior to the Void Swallowing Flame and the Purifying Lotus Demon Flame, but combining the Bone Chilling Flame to beat the fourth ranked Golden Emperor, Fen Tianyan, was not a problem at all.

After swallowing the Black Yellow Flame and fusing it with the thick characteristics of the Black Yellow Flame, the Blood Gold Flame would probably be a step closer to Di Yan. At that time, with just the Blood Gold Flame, Li Dao would not even need to use any other means to suppress Gu Yuan and the Heavenly Soul Emperor.

If he were to successfully fuse the Heavenly Flames, Li Dao would not even be able to imagine how much stronger his battle prowess would be. He might still be in the Heavenly Immortal Stage, but his battle prowess was such that even Golden Immortals would be able to make it up to him.
