Walking out of the passage, Shi Zhiyi's eyes were greeted by a river of lava more than ten zhang wide, with endless flames and surging heat waves, winding from a very far place. 【】In this river of lava flowed a tumbling crimson magma, like a river of hell, burning a vast space underground.

This river of lava, when it flowed to the place in front of Shi Zhiyi's eyes, was blocked by some force, and the rolling lava poured into a huge fire pool with a radius of more than 100 zhang, and stopped moving forward.

Above that huge fire pool, there was an ice-blue formation with a diameter of hundreds of zhang, which firmly suppressed the endless flames contained in the fire pool, allowing the lava to roll and burn the sky, but it could not break through the shackles of this ice-blue formation. The crimson flames continued to hit the formation, and the momentum was extremely terrifying, but it did not stir up even the shallowest ripples.

Above the formation, there were dozens of straw-like ice-blue passages, about a foot thick, that ran from the fire pool to the top of this underground space. In these passages, the most essential flames can be seen being sucked out of the fire pools and sent upwards along the passages.

"Earth's Heart Fire Vein!" Shi Zhiyi couldn't help but be taken aback when he saw the scene in front of him.

The Earth's Core Fire Vein is a natural wonder that can only be formed by the Earthfire Essence after hundreds of thousands of years, which is extremely rare, and Shi Zhiyi can only recognize it because he has seen similar places in Yunqi City before.

The flame of the fire vein in the center of the earth is the best choice for alchemy and refining, not only the temperature of the flame is extremely high, but also the firepower is stable, and it can be maintained for tens of thousands of years or even longer without extinguishing or even weakening, which is a miracle that all the top forces dream of.

The alchemy refiner with the fire vein in the center of the earth not only produces extremely high grades, but also as long as the raw materials are sufficient, it can mass-produce high-quality pills and blades, which is of self-evident significance to a top force.

When Yunqi City was founded, it discovered an excellent grade of the Earth's Core Fire Vein in the depths of the Jade Belt Mountain Range, and it took thousands of high-level array mages three years to successfully subdue it, making it one of the treasures of Yunqi City.

However, due to the topography of the Great Plain of Guiyan, where Kyoto is located, it is rare to hear of the existence of the geocentric fire vein, let alone in a place so close to Kyoto. Presumably, the ancestors of the Daxi family discovered this geocentric fire vein by chance, and then built a detention village on it to hide people's eyes.

Shi Zhiyi was looking at the huge pool of lava fire in front of him when he suddenly heard a ping-pong sound from his left hand.

I saw that there was a one-and-a-half-foot square hole in the ceiling on his left, and a pile of garbage fell out of the hole.

Below the entrance of the cave was a huge mountain of garbage, the highest point was about three or four zhang, and the length was about ten zhang. There were all kinds of broken bricks, gravel, dead branches and leaves, food scraps, etc., and this mountain of garbage spread from the wall on Shi Zhiyi's left hand side to the shore upstream of the fire veins in the center of the earth.

Under the roasting of the fire veins in the center of the earth, some garbage has been dried and spontaneously combusted, while others are far away, but they are rotten and deteriorated, emitting a foul smell.

Obviously, the village uses this geocentric fire vein as a natural garbage incineration site, dumping some daily garbage directly through the channel and letting it be burned naturally, which is convenient and labor-saving.

Shi Zhiyi's eyes left the garbage mountain, and he was about to observe the geocentric fire vein in front of him again, but on the other side of the garbage mountain, there was a sudden quarrel.

One of the thick voices, Shi Zhiyi could hear clearly, it was from Helian Mingzhi, who had experienced life and death together, but had been separated for more than half a year!

Shi Zhiyi's mood suddenly became excited, he put away the Qingshao sword, jumped over, jumped over the top of the garbage mountain, and jumped to the other side.

What appeared in front of Shi Zhiyi's eyes was a cage made of steel the thickness of an adult man's calf, and four ragged men were locked up inside, competing with each other for the half of the fish that Shi Zhiyi had just seen.

The cage was about two or three zhang long, about one zhang high and one zhang wide, and one end of the cage was close to the huge mountain of garbage, and the juice from some of the garbage decay merged into a thin stream of water, which flowed close to the cage.

For Shi Zhiyi's arrival, these four people obviously didn't notice that at this time, their energy was firmly occupied by most of the sweet and sour fish.

Among these four men, one of them is dark-skinned, tall and strong, like an iron tower, and tightly protects most of the fish in his arms, which is the target that Shi Zhiyi wants to save on this trip: Helian Mingzhi!

Compared with Helian Mingzhi, the other three men were all old, fat and thin, and they were three unkempt and bearded little old men. Compared with Helian Mingzhi's tall and strong body, their figure is really not enough to see.

At this moment, an old man was hugging Helian Mingzhi's right leg tightly, another was holding his left arm, and the other climbed onto Helian Mingzhi's back and hugged Helian Mingzhi's neck tightly with two arms.

"Helian boy, hurry up and hand over the fish! Since you came, you have robbed you of most of the good things here, don't deceive people too much!"

"That's it, hurry up and hand over the fish, and the four of us will divide it equally! Otherwise, no one will want to eat it!"

"Helian boy, let's discuss, you divide half of the fish, if we can go out one day, what gold and silver treasures, how much do you want!"

"You three are here again! How many times have I been in charge of you! I said that I would divide it evenly, and in the end, all of them were the worst ones! You hurry down, or I'll be welcome!"

"Hey, it's good to have you a share! If it weren't for the old man's strength not being able to exert his strength, which round would get you to be arrogant! If this is outside, you just kneel down and beg me, the old man may not be willing to look at you more, now you can have the opportunity to share food with me, it is your honor!"

As the old man spoke, one hand grabbed Helian Mingzhi's arms, and he was about to catch the sweet and sour fish that was missing a fish head.

Helian was in a hurry, and shook himself hard, and the three old men were thrown out by him almost at the same time, hitting the stainless steel railing, and suddenly let out a cry of pain that had been oops.

"Are you all right, hurry up, I'll share your share!" Helian Mingzhi scratched his head as he looked at the three old men lying on the ground screaming but didn't get up.

At this time, an old man lying on the ground finally saw Shi Zhiyi standing on the side, got up with a wheel, and looked at it: "There is a new person coming?"
