The dry cave was filled with the smell of sulfur, and as Zheng Hao went deeper, the pungent smell became stronger and stronger, and the color of the cave rock gradually changed.

Looking at the glazed dark red rock, Zheng Hao couldn't help but ask Six Wings, "Where is the fire attribute energy crystal?" How far is it going? ”

Judging from the distance Zheng Hao has walked, it has gone far underground here, and he can't help but be a little worried about Fang Zhiling who stayed in the wooden house villa outside, if this little girl wakes up and doesn't see him, she will definitely be anxious.

"In the strengthening of fire attribute energy fluctuations, there must be a fire attribute spar mine here."

"Okay, we're going to have to speed up." Zheng Hao was too lazy to follow Liuyi's instructions and gradually explore the cave.

He cared about Fang Chiling, and directly cast 'teleportation', and his figure suddenly disappeared into the spiral-shaped deep cave.

It's a fiery world, home to lava, and the smell of sulfur rising from the tumbling lava lake fills the entire space.

Waves of blazing heat rose from the surface of the dark red lava lake, directly enveloping Zheng Hao, and the silk bathrobe on his body suddenly turned into ashes.

"Sure enough, it's here, so rich in fire attribute energy!" Zheng Hao didn't care about his nakedness, his eyes were attracted by the clusters of shiny hexagonal crystals in the lava lake.

The hexagonal crystals that loom in the tumbling magma are translucent and bright red, about a meter long, and the thickness of an adult's arm.

They huddle each other in clusters, like lotus flowers in full bloom, rising and falling in the lava lake.

One flower, one flower, another flower.

Like a happy bee, Zheng Hao used his levitation technique to shuttle across the lava lake, constantly picking hedron lotus flowers to collect into his storage space.

Soon, the fire attribute spar lotus floating on the lava lake was collected by Zheng Hao, and the six wings were like a monster that couldn't get enough to eat, constantly turning the fire attribute spar in the storage space into energy points.

Finding that his crystal energy was constantly rising, Zheng Hao was very happy, once he was able to obtain the speed of blood demons coming and going without a trace, he would be invincible in this world.

"It's only 4,000 points of crystal energy, where is the spar vein?"

After the six wings absorbed the fire attribute spar collected by Zheng Hao, Zheng Hao found that the crystal energy he possessed was still a long way from the 10,000-point mark, and he couldn't help but ask the location of the six-winged spar vein.

After a moment of silence, the Six Wings replied, "At a distance of 60 meters from the host, there are fire attribute energy fluctuations. ”

"60 meters?" Zheng Hao's gaze locked on the position indicated by the six wings.

It was a piece of land that was about two or three hundred square meters above the surface of the lava lake, and it was littered with large and small red solidified lava stones.

"What is this?"

Arriving at the location indicated by the six wings, Zheng Hao was surprised to find that among a pile of boulders, there was a strange red flower growing.

It was a plant that closely resembled a lotus flower, and Zheng Hao was sure it was a plant, and he could see that there was a sap-like substance flowing in the ruby petals.

The lava lake is in a huge cavern deep underground, an underground space of about one square kilometer or so, with a blazing heat capable of melting steel.

And the air is also filled with all kinds of poisonous gases that are deadly to humans, and it is incredible that there are plants in such a harsh environment.

Zheng Hao soon discovered that he was rare and strange, there were not only plants in the lava space where there could be life, but also animals, and more than one.

"I'll it! What is this thing? ”

Zheng Hao didn't have time to explore why plants could grow in the lava space, so he directly stretched out his hand to uproot the lotus-like plants growing in the rubble.

But before Zheng Hao's palm touched the strange plant, out of the corner of his eye, he found a fiery red shadow crashing towards him.

Boom!!!

With a muffled sound, Zheng Hao was like a baseball that had been hit with all his strength, and was knocked away from afar.

"Damn! This guy has a lot of strength! ”

Pulling himself out of a solidified lava boulder, Zheng Hao looked at the humanoid depression on the boulder behind him, and couldn't help but touch the place where his chest was hit, where he felt a hot pain.

Zheng Hao has an indestructible Hamba metal formation of an immortal body, and he does not take any physical damage, but he still has a sense of touch, he can feel pain, but it is only pain.

"Shhhh Hiss... Hiss..."

Glancing at his silver-white chest, Zheng Hao looked around and found that he was surrounded.

Directly in front of Zheng Hao, between him and the strange plant, was a strange-looking snake-shaped monster.

There were a total of six such monsters around Zheng Hao, two of which were larger, wrapping Zheng Hao one after the other, and the other four snake-like monsters that were obviously a few sizes smaller were scattered around, looking at Zheng Hao with their heads probed.

"Human! You've broken your promise, and this is a forbidden place you can't set foot in! ”

A cold voice suddenly sounded in Zheng Hao's sea of consciousness, Zheng Hao couldn't help but be slightly stunned, and it took a while to understand that the snake-shaped monster opposite him was actually able to communicate with him.

"This is a high-level demonic beast." Zheng Hao looked at the flames that appeared as the snake-shaped monster's mouth opened and closed, and asked Six Wings, "What is its soul energy value?" ”

"$20." A moment later, Six Wings gave Zheng Hao an incredible statistic.

"20 yuan? Isn't that twice as much as mine? ”

"With the host's current soul energy value, it can't cope with the impact of soul energy when it dies, and it can kill second-class prey, so it is recommended to kill it immediately!"

The cold electronic sound of the six wings sounded, giving Zheng Hao a big temptation, "Killing all the secondary monsters can get 12 yuan soul energy points." ”

"That's a big job!" Zheng Hao licked his lips and was a little embarrassed.

In the lava lake full of flame energy, in the face of a group of fire-attribute monsters that occupied the main location, Zheng Hao was not sure of killing them in one fell swoop.

This group of monsters that are even faster than him, if they drill into the lava lake, Zheng Hao really can't do anything about them.

"Human! Why are you still here? You've finished harvesting the fire crystals this time, so don't forget the tribute you need to pay. ”

"Harvesting fire crystals? Tribute? ”

The information revealed in the words of the snake-shaped monster made Zheng Hao very curious, and Zheng Hao immediately understood that this monster was treating him as Gao Pengfei.

With the blazing heat in the lava lake that can burn skin and bones, only Gao Pengfei, a fire attribute enhancer, can enter and exit the entire hot spring town freely.

Thinking of this, Zheng Hao's previous doubts were also solved, why this town with a population of thousands could still survive with the fact that the hot spring town was not a strong defense.

In the world after the mutation, each powerful demonic beast has its own fixed territory, and before this demonized beast dies, no other demonized beast will enter without permission, otherwise it will mean an endless battle.

Fire Attribute Enhancer Gao Pengfei was able to enter the lava lake to harvest fire crystals, he must have reached some agreement with the master here, otherwise the snake monster would not have any words like tribute.
