Jia Zhengjin dug all the way down, specifically picking diamond mines, and he was very happy.

When five or six hundred diamonds appear in the backpack, the bottom becomes normal limestone.

Five or six hundred diamonds! That's a pretty rare catch. Although the transaction price of a diamond is only 1,000 gold coins, it is worth at most five or six hundred thousand yuan, but it is rare!

Continuing to dig down according to the steps, he didn't know that he had descended a few hundred meters, and when he felt a little bored, a huge cave appeared under the next dug block.

The hole I dug myself, and it was pitch black below, and the ground could not be seen.

Even with night vision, visibility is limited, and it appears that the cave is quite deep.

"Flash Technique!" Switching the ring with flash magic, Jia Zhengjin decisively released a ball of light for lighting into the cave, and when it slowly fell, he lay on the ground and poked his head into the hole to check.

The ball of light illuminated the environment inside the cave, and below it was an incomparably wide space, at least the size of a football field. Then there was no bottom below, and the ball of light kept going down but couldn't see what was going on at the bottom. In the end, even small dots of light can be seen continuing to move.

"This is too deep, isn't it?" Jia Zhengjin swallowed nervously, and retreated in his heart.

The key is that you can't summon an imposter dragon here, otherwise you will be able to fly all the way.

Don't look at the area in front of you is very wide, who knows if the terrain will change if you go down?

But looking back at the depth that was finally dug out, coupled with the irrepressible curiosity in his heart, Jia Zhengjin thought about it for a long time, and finally gritted his teeth and took out the scout's aircraft equipment, and then jumped into the cave.

The body lost its support and fell wildly inside the huge hole, completely unable to see the environment around it that was moving upwards at a rapid pace.

He didn't rush to start the craft, but let himself fall vertically, all the way to the dark depths of the earth.

I didn't know how long I was falling in the air, but I felt that the cave would widen and narrow at one point, but the bottom would always be empty.

There were several times when he couldn't resist giving up and using the aircraft to return to the ground. But in the end, he resisted the impulse, and fell endlessly towards the "bottomless pit" in the darkness.

He didn't know how long he had been flying, and it felt as if half a century had passed, until he was shivering by the cold phoenix, and his consciousness gradually blurred with tiredness, and finally saw the ball of light that stayed below, proving that it had touched the ground.

Jia Zhengjin hurriedly turned on the flying machine, stopped his high-speed falling state, and then slowly moved towards the ground.

The moment my feet stepped on the ground, I finally felt a sense of solidity. Looking up at the depth, I don't know how much I don't know, let myself fall into the vertical cave for a long time, take a few deep breaths to regulate my breathing.

"Sure enough, it's an extremely deep place, and people who can't fly will fall to pieces directly!" Jia Zhengjin could clearly hear the sound of his heart pounding, and cold sweat kept pouring out on his forehead.

Control the ball of light to fly up and start taking a closer look around.

The bottom of the wide cave is full of irregular rock walls, and many strange-looking stones are densely displayed.

"Passage?" The ball of light took Jia Zhengjin to illuminate the surrounding area in the cave, and soon found a rather hidden road. The road is on top of the rock wall, so it is difficult to spot without looking closely, and you will think that it is just a crack in the rock.

Climbing up cautiously, the probe glanced into the crack, and there was something else inside, and there was a faint red light.

Jia Zhengjin first tentatively controlled the ball of light and flew into it so that he could understand the internal structure, and then slowly followed behind the ball of light, moving forward in the crack channel little by little.

After walking for about a few tens of meters, the front became wider and wider, and finally turned from a crack in the rock wall to a normal passage.

However, to Jia Zhengjin's surprise, the temperature inside suddenly rose again, and he didn't feel it at all when he took a step back. It's like there's a clear dividing point that divides the two worlds on both sides of the road!

Hundreds of meters forward in the scorching environment, a huge magma pool suddenly appeared in front of me.

No wonder the temperature is so high!

Jia Zhengjin glanced at the opposite side of the magma pool, which was a rather wide opening, and it was the only passage. So without hesitation, he took out the iron bucket and scooped out the magma again.

When all the buckets were used up, the magma pool in front of him finally disappeared.

It's just that this time in the magma pool, there was still a strange fish with a fiery red body, emitting a lot of heat, and jumping around. It resembles a catfish, a colored catfish that is on fire......

"What the hell?" There were fish in the magma, which made Jia Zhengjin arrive in disbelief.

The fish jumped through the ashes of the lost magma, and its body was half the size of an adult, showing considerable strength.

After watching it jump for a while, Jia Zhengjin felt that he still had to figure out what this thing was. So take out the trident, approach it carefully, and then stab it hard.

【System】You kill the Lava Fish and gain 1000 XP!

"Lava fish?" Jia Zhengjin looked at the fish that was directly killed in seconds, it was actually quite weak. Reaching over and cautiously approaching the body of the fish that seemed to be burning, he found that his hands were not hot at all.

【System】You have obtained delicious lava fish!

【System】You have obtained the Lava Fish Eyeball!

【System】You have obtained the Heart of Fire!

【Delicious Lava Fish】No need to cook, it's already cooked!Immediately recover 50 HP, 50 mana, and 50 durability after eating!

【Lava Fish Eyes】Underground humans in ancient times often hunted lava fish and used their eyeballs as luminous lamps.

[Heart of Fire] has a nice kick-up effect on fire mages.

In such a deep place, and there are creatures in the magma, it was really unexpected by Jia Zhengjin, and it subverted his cognition.

But when I think about it, everything in this other world is inherently different from Earth. Even gods and demons exist, as well as countless strange races and creatures, and it is not surprising that even stranger things appear!

What made Jia Zhengjin even more curious was what was in the depths of the cave that could bind the forsaken for thousands of years?

Pack up your mood, fly over the magma ash layer, and quickly move forward after landing into the cave.

The cave was also spacious, and unlike the scorching heat of the previous environment, it was quite wet, and there were even dripping of groundwater from the stalactites hanging from it.

It's so close, how can there be underground water on one side of magma? It's incredible!

Even after walking a little further, there was a small river formed by underground water, and the clear water was bitterly cold.
