The hot air balloon slowly rose in the sound of "snorting" flames, and the flames two or three meters high sent a wave of heat, and everyone felt like a split-hoof steak in the oven. Felder touched the hair on the top of his head, feeling the smell of burning.

"Hey, old man, aren't we going to the Great Rift, and if we fly any further down, we'll hit the frozen cliffs. Felder wondered as he looked at the flames not far overhead.

"Where is all this nonsense, lean this way, don't affect the operator to adjust the direction!" Old Neil had just finished speaking, and the flames began to weaken rapidly.

"The heat is balanced. Dabao shouted as he turned the valve.

"The wind speed is about one meter per second, and the wind is southwest. Dabao stared at the anemometer above his head and said very professionally.

Under the manipulation of Guy and the others, the hot air balloon had floated above the deep darkness. The flames became smaller and smaller, and the hot air balloon seemed to start shaking a little, but the imaginary feeling of weightlessness did not come, and the hot air balloon landed very smoothly and slowly. As the flames continued to increase and weaken, the rattan basket hit the ground with a muffled sound.

The deflated balloon skin covered everyone like an impenetrable net. One by one, everyone climbed out of the rattan basket and lifted the balloon skin to get out.

"Ahem......" Ace fanned the dust in front of her eyes with her hand, covered her nose and coughed a few times.

"Is this the Great Rift?" there was a deathly silence around them, and Vane's voice echoed in all directions. He stepped on the ground and noticed that the soil was a little soft.

"Where's the furnace?" said Elena, pat the dust off old Neil's head. The width of the fissure should have been more than 100 meters, and the miner's lamp shining on the opposite rock wall turned into a huge spot of light that was almost invisible.

The goblins quickly put the hot air balloon together with the help of the Simpsons. Guy pointed to the distance and screamed, "Now, it's in the mine over there." You'd better come back quickly, I'm going to finish my propulsion system tomorrow. ”

Looking closely, there was a little bit of light in the direction of Guy's finger. Old Neil took out a portable magic lamp from his toolbox and handed it to Simpson. The magic lamp emitted a faint blue glow, and it looked as if the magic stone was about to run out, but anyway, the surroundings were finally not so dark.

The soft dirt beneath his feet was a bit of a struggle to walk on, reminding Wayne of the snowy streets of Obojar. The light of the magic lamp was like a firefly in the dark, slowly drifting into the distance.

"Actually, you didn't need a hot air balloon to get here, you can get there by lift, but the lift has been abandoned for a long time since that incident. Old Neil's heavy, slightly aged voice echoed through the Great Chasm.

"Is it a caveman?" Vane asked, quickening his pace to catch up with old Neil.

"That's right. Old Neil nodded, he adjusted the angle of the lamp, and continued, "It was a long time ago, one day the dwarven miners were in the cave of the Great Rift, mining veins as usual, and my father was also smelting ore. The old-fashioned dwarven TBM, though clumsy, was capable of digging tunnels, and the driver inadvertently opened up the tunnels and cavemen's caves. Savage cavemen poured out with weapons and brutally killed my father and the other dwarves......"

"Alright, that's it. When people are old, they like to be verbose, haha. Old Neil laughed dryly, and fell silent. The crowd didn't know what to say, and the atmosphere became slightly dull.

"I'm feeling hotter and hotter. Elena said as she wiped the sweat from her face with the back of her hand.

"The deeper you go, the hotter it gets, I don't think you can walk, Captain Elena!" Felder quipped.

"No, it's unusually hot here. Old Neil, who was walking in front, slowed down, and he turned his head and said, "There is a mine in front of you, and although the cavemen have no sharp weapons or powerful magic, they must not be taken lightly. They tend to give you a fatal blow from the shadows when you let your guard down. ”

After a while, everyone came to the entrance of the mine. The logs supporting the entrance to the cave were already a little rotten and crooked, the fallen gravel on the ground was covered with thick dust, and the corners of the cave were covered with cobwebs.

"Can you still go into this mine?" Felder hesitated.

"Don't worry, I've been here once before, and it's totally fine. Old Neil said as he tossed off the cobwebs and prepared to enter.

"Before?"

"Thirty years ago. ”

“......”

The main aisle of the mine is very wide, and it is not crowded when people walk side by side. Iron pickaxes, discarded miner's lamps, and some strange mechanical parts are scattered all over the place. A rusty minecart is parked on the railroad tracks in the middle of the tunnel, silently telling the sad history.

"Wait. Old Neil motioned for the group to stop, cautiously approaching the alleyway wall on the left.

Above the walls, a viscous golden liquid flowed slowly, forming irregular bands or speckles. Some are flowing down the walls, forming dark red deposits in the corners.

"Be careful, everyone, this is magma, and if you touch it, you won't even have any bones left!" said Old Neil in a low voice, frowning. Although it is thousands of kilometers underground, I have never heard of magma before. This is obviously something out of the ordinary.

"Simpson, come and see what this is......" In front of Ise was a dark mass, her voice trembling a little, and she slowly took two steps back.

Simpson leaned over with the magic lamp.

"Ahh Ace gave him a grateful look.

The pitch black thing on the ground was a huddled corpse, burned like coal by flames. The corpse looked like a human, but the head, hands and feet were on the large side, and the overall appearance had a sense of incongruity.

Old Neil squeezed over, looked at the corpse on the ground and said to himself, "It's a caveman, strange, why did he die here?"

Stranger things were yet to come, and as we progressed deeper into the lanes, more troglodyte bodies were discovered. Some only have a pile of skeletons left, but all of them have traces of being burned.

The temperature around them became hotter, and everyone Vane took out the kettle and drank it in a big gulp, fortunately listening to old Neil's advice, otherwise he would have to die of dehydration.

At this moment, a low roar was heard, and several glowing red eyes appeared in the darkness not far away.

"It's a wolf!" Felder shouted, scrambling to draw his steel sword and make a defensive stance.

How could there be wolves here? Before Wayne could think about it, those red-eyed things were snorting and panting, and in the blink of an eye, they were already approaching everyone.

Old Neil, who was at the front, did not retreat, but swung his hammer forward. The blow was so powerful that it brought a gust of wind.

"Boom!" came a muffled sound. The red-eyed monster was smashed and flew out, letting out a strange scream. The monsters behind only paused, and immediately bullied forward and pounced on Old Neil.

"Whoosh!" the bowstring in Elena's hand hummed and vibrate, and a white-feathered arrow burst through the air, instantly piercing the body of a monster. The force of the impact caused the arrow to plunge diagonally into the stone wall.

It all happened in a short period of time, and Vane and Ace didn't even have time to chant the incantation.

The remaining monsters were already leaping into the air, their eyes glowing even red, and dark red sticky saliva flowing from the corners of their mouths. Old Neil swallowed, his heart felt a little cold, his broad palms clenched, and he picked up the hammer and smashed it at one of the monsters.

Just then, a figure appeared beside Old Neil. He swung his giant sword and slashed at the monster, his wrist shaking, and the broad blade turned into several phantoms.
