Xu Feng cautiously entered this cave, and as soon as he stepped in, a scorching breath suddenly came to his face, and he felt that the blood all over his body seemed to be boiling, and the temperature around him was at least more than a hundred degrees higher than outside;

System: You step into an unknown realm where the temperature exceeds the limits of your body's capacity, and you will continue to lose 120 HP in the next ten seconds;

System: Your body is burned (level 1) and loses 120 HP every 10 seconds, which is removed when you leave the area;

Xu Feng stood at the door for a moment, his intuition guided him in the direction, it was the depths of the cave, after hesitating for a moment, he finally raised his feet and walked towards the depths of the cave;

The cave emitted a dark red light, the ground was flowing with hot magma, and all around it were piles of lava tens of meters high, and there was a burst of sound from time to time in the distance.

Xu Feng followed the guidance of his intuition, swept towards the depths of the cave, and did not find any monsters along the way, and soon, a magma lake appeared in front of Xu Feng's eyes, the scorching magma lake surface, constantly tumbling bubbles, and the heat wave rolling.

System: Your body is burned (level 2) and you lose 280 HP every 10 seconds, which is removed when you leave the area;

The deeper you go into the cave, the higher the temperature, and the greater the damage you will receive, but with Xu Feng's current millions of HP, it is enough to sustain exploring here;

Looking across the lava lake, you can see a large shadow that looks like an abandoned castle.

"Maybe that's where I'm going!" Xu Feng secretly said in his heart, just when Xu Feng was hesitating how to cross this magma lake, he suddenly found that on the shore near the magma lake, there was a red, less than a foot plant, shining with agate-like brilliance.

Xu Feng quickly swept towards there, and found countless wrecks along the way, and a burst of mournful screams could be faintly heard around, as if there were ghosts surrounding him;

Slowly stopped, Xu Feng found that the one that was shining with agate-like gemstone light was not a plant, it looked like a work of art, the whole body was carved with red crystal, and the surface was inlaid with gems of various colors, red, yellow, green, very exquisite;

"What is this?" Xu Feng frowned slightly, and lost an insight technique, but he could only see the name and quality of this item;

"Treasure Box (Openable), Quality: Legendary, Attribute: ???"

"Can be opened, is it something like a treasure chest?" Xu Feng was overjoyed, but he didn't act immediately, he saw that around the treasure box, there were a lot of bones scattered, these bones were scattered in the surrounding stone crevices like garbage, one bone was seven or eight meters long, and there was a silver-white horn on the skull, although these bones had been weathered very seriously, but Xu Feng could feel how fierce they were when they were alive from these bones.

These things made Xu Feng's heartstrings tense for a moment, and he didn't know if there was any guardian beast hidden around here, or some kind of trap or something.

Otherwise, where did so many bones come from?

Xu Feng hesitated for a long time, glanced at the ancient castle opposite the magma lake pointed to by the intuitive guidance, and stared at the surface of the lava lake that was constantly tumbling and foaming, and frowned slightly;

After thinking about it for a long time, Xu Feng was still a little reluctant to give up this treasure box, it was a legendary quality item, and after opening it, he could get at least one legendary quality treasure, and if the treasure was opened here, it would definitely be a treasure above the planetary level, and it would be priceless.

Thinking of this, Xu Feng's heart moved, and two soul insect soldiers appeared beside him, and dark red traces appeared on the bone armor of these two soul insect soldiers, looking as if they had just come out of the blood pool, exuding a fierce aura all over their bodies.

These were two planetary-level insect soldiers, standing motionless next to them after being summoned by Xu Feng, like two statues.

"Let's try it!" Xu Feng motioned for the two soul insect soldiers to approach the treasure box.

From the moment Xu Feng's order was issued, the two insect soldiers suddenly became smart, and their scarlet eyes stared at the treasure box in the distance, sweeping forward like lightning.

Just when the two insect soldiers were less than ten meters away from the treasure box, the lava lake next to them suddenly boiled, and a creature that looked like a huge earthworm suddenly drilled out and spat out a ball of fire towards the two insect soldiers.

Looking carefully at the huge flame creature, the round body, the surface is all condensed like rock-like skin, and the folds of the skin reveal crimson lava, and it makes a "click" friction sound when it moves, saying that it is a fire creature, but it is better to say that it is a magic puppet piled up by volcanic lava;

The movement of the insect soldiers was very fast, the moment this huge creature like an earthworm appeared, the two insect soldiers had already entered the combat state, and when the flames erupted, the two insect soldiers suddenly separated, one rushed forward, and the other rushed towards the magma lake.

Xu Feng lost an insight technique, and found that the other party turned out to be a planet-level eighth-order monster, on this planet, the planet-level eighth-order, it can be regarded as a high-level powerhouse;

"Flame Earthworm, Elite Boss, Planetary Level 8"

A simple introduction appeared in front of Xu Feng's eyes, and one of them made Xu Feng feel tricky;

"When the Flame Earthsalamander is in the magma lake, it can draw energy from the magma lake at any time to speed up its recovery!"

"Either bypass this lava lake or lure it ashore!" Xu Feng said secretly in his heart.

At this time, the insect soldier who rushed towards the flame earthworm swung his bone blade and slashed towards the opponent's body, the bone blade was extremely fast, and a white shadow slashed through the air;

Clang~

With a crisp sound, a palm-sized piece of lava bounced off the surface of the flame earthworm's body, and red and viscous blood gushed out like magma;

The flame earthworm let out a high-pitched chirp, and the back half of its body was hidden in the magma, and the front half of its body was like a heavy hammer, smashing towards the insect soldiers;

There was a loud bang, and the hard ground was smashed into a deep pit by the flame earthworm, but at this time, the insect soldier rose into the air, and the bone blade in his hand slashed towards a crimson fold behind the flame earthworm's head;

Call~

Just when the bone blade of the insect soldier was still one meter behind the head of the flame earthworm, a flame earthworm suddenly jumped out of the magma lake, biting the insect soldier in his mouth with a big mouth, chewing constantly, and in the blink of an eye, the insect soldier turned into a gray air flow and returned to the kingdom of God;

Immediately after, from the magma lake, a flame earthworm with four heads slowly walked out, the first one appeared the largest, the back head became smaller and smaller, and the last one was even only the thickness of a bucket, with eyes half-open and half-narrowed, looking listless.

Just as the entire body of the Flame Earthsalamander emerged from the magma, another insect soldier had already rushed to the treasure box, wielding a bone blade and slashing towards the treasure box;

This is a kind of temptation for Xu Feng, wanting to see if there is any danger in opening the treasure box;

The moment the bone blade touched the treasure box, the treasure box, which looked like a plant, suddenly bloomed with colorful light, and these rays of light pierced the body of the insect soldier like a sharp blade;
