After killing the Fire Spirit Snake and digging down the boiling groundwater, Wei Ziyang soon encountered the first Fire Spirit Stone.

"Pick up a Lower Grade Fire Spirit Stone*2"

When he saw the fire spirit ore, Wei Ziyang replaced it with the diamond pickaxe enchanted by Fortune, and only then did he open two fire spirit stones.

As soon as I dug down, I encountered more and more fire spirit stones. This vein of fire spirit stone has never been mined by anyone, and it is a rich mine, and Wei Ziyang will really not be able to dig it up for a while. Fortunately, he had enough food with him, and it didn't matter if he was tired and rested on the spot.

On the third day, Wei Ziyang had gone deeper than 200 meters underground.

The environment here is already very bad, the whole thing is like a steamer, and Wei Ziyang is sweating even if he has system protection. However, the harvest is getting better and better, at the beginning it was only a low-grade fire spirit stone, and gradually the grade of the spirit stone began to improve, from the lower grade to the middle grade, and when it reached the central area, most of them were high-grade grades, and each piece contained a huge amount of fire spiritual power.

Anyway, Wei Ziyang really made a fortune this time, if he could dig out a superb spirit stone again, it would be perfect.

"Knock ......"

Another pickaxe went down, but there was an unusual echo, and there seemed to be another space under the rock.

But how is that possible? This is not the base world.

"Boom!"

With another hammer, the rock at the bottom finally shattered, but the block fell downward.

There's room down there.

Wei Ziyang cautiously looked down, but was stunned on the spot.

Underneath is a large cave structure, but it is not a natural formation, and it is clear that there are traces of man-made construction.

There are dragons and phoenixes carved around, and a large number of fire spirit stones are inlaid, and it seems to be arranged according to a formation, because he can't see the overall situation, Wei Ziyang can't judge what the origin of this formation is.

There is a dry pool in the center of the cave, and there is still some volcanic ash left on it, and I think the pool originally contained magma, but I don't know why it dried up later.

What's even more strange is that the magma pool is surrounded by rocks, and it looks like something that originally surrounded the magma pool has been dug up, and the whole thing is out of place.

"Could it be that someone has ever been here to dig up treasures? But there is no reason, the surrounding walls are all high-grade fire spirit stones, which are very valuable, why don't the other party dig them up together?" Wei Ziyang was very confused.

But it didn't seem that there was any danger below, Wei Ziyang jumped down gently, although the cave was twenty or thirty meters deep, but Wei Ziyang was as light as a swallow now, and this height certainly wouldn't let him fall to death.

"Buzz!"

At the moment when Wei Ziyang landed, the cave wall suddenly burst into brilliance, and every spirit stone on it lit up, and a mysterious energy converged towards the center.

Wei Ziyang didn't expect such a change, and the whole person tensed.

After a period of brewing, the formation finally projected a phoenix phantom. Although it was just a phantom, the moment it opened its eyes, Wei Ziyang still had a heart palpitation, a very powerful remnant soul.

"New Lord of the Dragon Domain, you're finally here!"

The phoenix phantom speaks.

“...... What?" Wei Ziyang suspected he had misheard.

He had heard the term the new lord of the Dragon Domain once, although he remembered it at the time, but he didn't think so, what did the new lord of the Dragon Domain have to do with him? But he never expected that now someone would actually call him the new master of the Dragon Domain.

Wei Ziyang had a funny face.

"The one who enters the center of the Phoenix Mountain is the new master of the Dragon Domain, and I will not be mistaken. Phoenix was sure.

"Don't don't, I'm just lost, goodbye......" Wei Ziyang turned around and was about to leave, this Lord of the Dragon Domain sounds majestic, but it is actually a life talisman, Dragon City wants his life, and the three palaces, six sects and seven factions will also want his life.

As for the prophecy of the Three Palaces, Six Sects and Seven Sects, if there is no matching strength, why should they obey you? Even if the Dragon City Lord is so powerful, the Three Palaces, Six Sects and Seven Sects are only 'superficial subordinates', once he goes out with the reputation of the Lord of the Dragon Domain on his back, the Dragon Domain is afraid that there will be no place for him.

"This is the destiny of heaven, no one can avoid it, you are just a sign of cowardice. The Phoenix Phantom said without hurry.

Wei Ziyang's footsteps stopped suddenly.

"The catastrophe of the Dragon Domain is coming, if the new master does not return to his position, the Dragon Domain is in danger. The phoenix phantom said.

Wei Ziyang paused before saying: "I once heard a prophecy, saying that the true dragon will come out, the new lord will appear, and the three palaces, six doors and seven sects will worship." Fudong Domain, set the Quartet, and regain control of the Dragon Court! This has nothing to do with me, does it?"

"Five thousand years ago, the last Lord of the Dragon Domain prophesied at the last moment of his life. The phoenix said slowly, and then asked, "You really haven't summoned a real dragon?"

"Summoning a true dragon?" Wei Ziyang stared.

"Then I'll make it clearer, what did you do in Longshan?" Phoenix reminded.

"You mean...... Wei Ziyang suddenly thought of inviting Brother Long to help in the Dragon Palace, what did the real dragon mean when he came out? Wei Ziyang suddenly wanted to cry without tears.

"Looks like you've identified yourself. "Phoenix Road.

Wei Ziyang's mind was a little confused, but he still asked his own questions: "Legend has it that the master of the Dragon Domain used to be a dragon clan, and I am a human race, so it's not appropriate to be the lord of this Dragon Domain, right?"

"The luck of the dragon clan has come to an end, and the world is destined to be the leader of the human race, and the destiny of heaven cannot be violated. Phoenix said in a deep voice.

"That'...... What should I do now?" Wei Ziyang had to ask.

"Phoenix Mountain and Dragon Mountain are the Dragon Domain Qi Valves, but now they have been destroyed by the powerhouses of the Eastern Regions, and now you must repair them to revive the Dragon Domain's Qi Luck. Phoenix said loudly.

"How can this be fixed?" Wei Ziyang looked at the mess in front of him and suddenly frowned.

"There used to be one hundred and eight top-grade fire spirit stones around this geocentric pool, but now they have been dug up by the powerhouses of the Eastern Regions, you first need to repair the geocentric pool. The phoenix looked around the magma pool and said to Wei Ziyang.

"It turns out that this is called the Geocentric Pool...... But one hundred and eight top-grade fire spirit stones, where can I find them?" Wei Ziyang had a dark face, even if he combined all the fire spirit stones he had dug up before into top-grade fire spirit stones, he would not be able to count them.

"The main function of the best fire spirit stone in the core pool is to be able to withstand the temperature of the core of the earth, and other things can also be replaced, as long as it can stably withstand the permanent incineration of the core fire. Phoenix explained.

"In that case, there are still some ways to ......"

Wei Ziyang immediately thought of obsidian, the so-called geocentric flame, which actually means magma, and obsidian is accompanied by magma in the basic world, which can completely replace the protective effect of fire spirit stone.

Coincidentally, there were still some leftovers in the game backpack, so Wei Ziyang took out a piece and tried to see if he could repair the core pool.

"Black Shine Divine Stone!"

The Phoenix Phantom exclaimed in surprise when it saw the Black Shine Stone.

"You also know that this is called obsidian?" Wei Ziyang frowned, and the shock in his heart was no less than when he heard that he was the new master of the Dragon Domain.

Obsidian should be unique to my world system, and other worlds should not have it, how can Phoenix know it?
