Fire Essence Mineral Vein, deep in the magma, inside the cave.
He had been mining Fire Essence Crystals for the past few days and had already collected tens of thousands of them. This was not a small number. If the outside world knew about this, even Invincible Saints and Half-Step Chaotic Sovereigns would be shocked.
Kacha!
Fang Chen had a joyful smile on his face. These days, he had already mastered the means of Empyrean Fire Saint. With the Hidden Star Sword in his hand, he was mining the Fire Essence Crystals with ease.
Beside him, the Fire Demon King was refining the Fire Essence Crystals from time to time.
Buzz!
A scorching energy revolved around the Flame Devil King's body. A Flame Essence Crystal on its claw instantly turned into powder. It opened its gong-sized eyes and was extremely excited.
"Although I didn't make a breakthrough, my strength has obviously improved." The Fire Demon King raised its head and looked at Fang Chen's back. It was extremely grateful.
If it wasn't for Fang Chen, it wouldn't have been able to use the Fire Essence Crystals even if it knew that there were Fire Essence Crystals here.
"According to my estimation, there should be about twenty thousand Fire Essence Crystals here."
Fang Chen muttered. He had already mined half of the Fire Essence Crystals. If he was given a few more days, he would be able to mine all the Fire Essence Crystals here.
"Phew."
He took a deep breath and placed a piece of Fire Essence Crystal into the Dark Cave Mountain. Then, his palm emitted a gentle light and injected it into the Hidden Star Sword. He then inserted the sword into the stone pillar.
Kacha!
A crisp sound rang out. Fang Chen felt a resistance that prevented the Hidden Star Sword from going deeper.
"Hmm?"
At first, he didn't pay much attention to it and increased his strength. However, not only did the Hidden Star Sword not go deeper, it even retreated a little. This scene attracted Fang Chen's attention.
"What's going on?"
He was puzzled. He had been using this method to mine the Fire Essence Crystals for the past few days and the process was very smooth. But why couldn't the Hidden Star Sword penetrate it now?
Could it be that there was another world in the stone pillar made of Fire Essence Crystals?
Thinking of this, Fang Chen's expression changed slightly. He carefully pulled out the Hidden Star Sword and gently polished the outermost layer of the stone pillar. Soon, the outermost layer of the Fire Essence Crystals automatically fell and was taken by Fang Chen.
"What is it?"
The more he polished the stone pillar, the more shocked Fang Chen became. That was because the resistance he felt was growing stronger and stronger.
Crack!
Fang Chen unhurriedly mined the outermost Fire Essence Crystals. He wanted to dig out all the obstructions in the surroundings to see what exactly was there that could stop the Hidden Star Sword from going deeper.
Finally, after an hour of digging, the outermost flame essence crystals all fell off. At this time, a faint blue light entered his eyes. Fang Chen turned pale with fright.
"What is this?"
Fang Chen used the Star Hidden Sword to lightly touch it, and sure enough, he felt a great resistance. He had already determined that the previous resistance came from the ore that was emitting a light blue radiance.
"Strange, why are there light blue ores growing in the Flame Essence Crystals?"
Fang Chen racked his brains but still couldn't figure it out.
However, his intuition told him that this light blue ore was very likely to be a rare treasure that was even more precious than Fire Essence Crystals.
"Master, what did you find?"
Fang Chen's strange movement attracted the Fire Demon King's attention. The latter stopped cultivating and came to the front of the stone pillar. He stuck his huge head out and looked at the light blue ore.
"Do you know what kind of ore usually grows in the Flame Essence Crystals?" Fang Chen pointed at the light blue ore.
The Fire Demon King's eyes widened as he stared at the light blue ore. His body trembled and his heart was in turmoil. His voice was a little hoarse.
"This … could it be …"
"What is it?" Fang Chen asked.
The Fire Demon King's huge claws were as fast as lightning as he grabbed the light blue ore. With a bang, a powerful force sent him flying.
He hurriedly got up from the ground and was even more convinced of his guess.
"Master is really the chosen one. You can actually find this ore." The Fire Demon King was full of praise for Fang Chen.
In the end, he told Fang Chen that this light blue ore, strictly speaking, was also a type of Flame Essence Ore. However, this ore was formed by gathering the essence of heaven and earth.
In other words, this light blue ore could be called a mother ore.
What was a mother ore? It was an ore that could give birth to a Flame Essence Vein. This ore was the most primitive ore and also the most powerful ore.
It was said that this ore was formed by the essence of heaven and earth and was very powerful.
"Flame Essence Ore."
After Fang Chen understood the situation, he took a deep breath.
"This is the legendary Flame Essence Ore?"
Even so, Fang Chen was still shocked. He had seen records of the Flame Essence Ore in the Heaven Defying Alliance's ancient books.
In the Battle of the Ancient Gods, all the Flame Essence Ores in the world were destroyed. There were no more Flame Essence Ores in the world.
He stared at the Flame Essence Ore that was emitting a soft light blue light. His heart was pounding. He didn't expect to find a Flame Essence Ore here.
"Master, the essence energy inside the Flame Essence Ore is very strong. Be careful." Seeing that Fang Chen wanted to dig the Flame Essence Ore, the Fire Demon King reminded him.
Fang Chen nodded and secretly set up a Demon Slayer Array, completely isolating this place. He was afraid that the movement would attract many giants outside.
"Flame Essence Ore."
Fang Chen was excited. His trembling hand slowly approached the Flame Essence Ore.
Hiss!
However, as soon as he touched the Source Ore, he felt a scorching power, as if it was going to burn his body. With a bang, he received a powerful rebound force and was sent flying.
After getting up from the ground, Fang Chen looked helpless.
"What a strong power."
Fang Chen couldn't help but sigh. "How can I take it away?"
The Flame Essence Crystal was already a rare ore in the world. Everyone would go crazy for it. The Flame Essence Ore was something that even Invincible Saints would fight for.
According to the ancient books, even a Half-Step Chaotic Sovereign like Palace Master Lei needed it.
Having the Flame Essence Ore meant that it was very likely that one could comprehend the essence of fire and obtain the title of Lord of Origin.
"It must be fast."
Fang Chen muttered to himself.
Once the giants outside finished their discussion, they would definitely enter the Flame Essence Ore. At that time, the Flame Essence Ore would be discovered by them.
Fang Chen was lost in thought. Beside him, the Fire Demon King was still in shock.
…
In a remote city relatively close to the Chaos Battlefield, the nine people led by the Young Marquis spent a few days learning about the area.
Just as they were about to lie dormant and wait for Marquis Xiaoyao to use his means to lure the top experts to the Chaos Battlefield, the Young Marquis's body suddenly trembled.
He flipped his palm and a fiery red token suddenly appeared.
Buzz!
The fiery red token vibrated and the inscriptions on it flickered. Seeing this, the other eight people's expressions changed drastically.
Whoosh!
The Young Marquis put away the fiery red token and jumped up with an excited smile on his face.
