When Mina came out of the other corner of the rock wall, the mutant dragon king who was already in a state of rage was still banging on the floor around him, looking like he was going to knock Mina out

However, Mina, who had already completed the replenishment of his magic power, directly hit several waves of Flame Flying Birds

After trying this a few times, this boss finally couldn't stand it, and a lot of things burst out, and this explosion also broke out two brilliant gems, as well as a skill book and a lot of gems

After quickly collecting the things on the ground and the materials on the boss's body, Mina also found a corner to sit down and rest, and at the same time he had to tidy up the somewhat messy backpack

In the backpack, Mina has already collected almost 25 brilliant gems, but looking at these 25 brilliant gems, Mina still feels that it is not enough

Because if Mina wants to upgrade the special items in his hand, then something like the Phantom Ring that has been strengthened once, then after that, each time it is strengthened, it will cost one more brilliant gem than the previous one

That is to say, if you want to rise to the highest level of the three rings on Mina's hand, you have to spend 15 although there is still a lot left, but, under the strong request of unscrupulous profiteers and thieves and others, Mina's coolie is decided

With a flare of fire above her head, Mina took a careful look at the passage to the 51st floor

Glancing at the mana and health that had recovered, Mina shot out of the lighting fireballs in front of him as she walked along the passage

However, this passage is obviously a bit long, and this walk actually walked directly for more than ten minutes, and as Shuina went down, the temperature became higher and higher

After checking the depth of this place through the system, it turned out that Mina had unknowingly come to the ground for nearly 1,500 meters

"It's ...... A lava lake? When Mina noticed the light ahead and moved forward, he felt a hot wind blowing in front of him, and then he saw a lava lake in front of him

"No, I actually dug directly to the center of the earth" Mina glanced back at the passage that could be here, and then at the space in front of him, which was larger than the main city, and he didn't know which direction to go for a while

The magma lake in front of him was so big that Mina thought of the ocean, but for some reason, Mina always felt something very dangerous in this magma lake

With such a feeling, Mina really didn't know whether to explore this huge underground cavern

"Fight, the more dangerous the place, the higher the benefit" Mina looked at the rocky path that led to the depths of this magma lake, knowing that this was definitely a fatal temptation

It's just that Mina has to go to this temptation

Glancing at the dome, which was hundreds of meters high, Mina naturally replaced the main element with the wind system

Through the Flying Technique, Mina first observed the surrounding situation, but he found that there was not a single creature here, not even the fire elemental creatures that liked this environment the most

For this kind of setting, Mina knows that this is impossible to appear in this game, and the more environments like this, the more big secrets should be, especially this kind of rock bridge that is obviously artificial

Because there is a rocky road over the lava lake, but there are no people guarding it, either there is nothing in it, or there is no need for these mobs to guard it at all

For this problem, Mina will naturally choose the second one, otherwise, the design here will be meaningless

After flying and checking in this place for almost 3 hours, Mina didn't touch a monster, but found some primitive ores of magic metals here, but the quality of these things is not very good, and Mina didn't plan to collect this

However, what makes Mina feel the need to stay here longer is that she can actually pick up brilliant gems here

And just as Mina thought, soon, he found a second brilliant gem and stepped on the addition technique, and Mina almost became the former gleaner, and from time to time he had to bend down to pick up or pick up the dirt to examine it carefully

"Damn, I knew there were so many brilliant gems here, I just went down and forgot it" Mina looked at the almost 70 brilliant gems in his backpack, and he also sighed with emotion

He has worked hard for so long, but he has not picked up as fast as here, and he is still very rough, he believes that there are still many brilliant gems here that have not been discovered

It's just that he doesn't have much time anymore

Originally, he planned to stay here for a few more days, but outside, Xiaomei and Ye Yan's promotion mission had already entered the preparation stage, and he had to go over to help, otherwise, his mailbox might be blown up by the beautiful fox and Xiaomei

Although the promotion of this priest is much simpler than that of other professions, this simplicity is also relative, and if there is no excellent equipment and skills, it is somewhat impossible to rush this promotion task

Moreover, the promotion of the priesthood profession still has to be carried out in the legendary Lost Forest

This place is not too dangerous, but judging from the feedback from the advance team, they all recommend that everyone find some good equipment and go there in a group of several people

However, Xiaomei, the guy, threw away these two efforts very directly, and directly found Shuina

"Alright, it's time to see what OSS is coming from here" Mina looked at the lava lake shrouded in scorching breath, and he saw that there seemed to be some buildings on the other side

At the end of the lava lake, near a rock wall, stands a very old underground palace

"Whew, it's really hot in here" Mina looked at the ground that was almost burned red, the temperature of the ground made him feel hot, and at the same time, he was actually burned, and it was dropping at a few points per second

Although he also saw a lot of magma in the elemental land of the fire system, the magma there was not as hot as the one underground, and it was close to the center of the earth, so the temperature was high

Started really? After the fire dragon possessed his body, the huge drop made Mina immediately groan comfortably, and now he only felt that the bursts around him were like a spring breeze, and the originally blazing environment became a heaven-like existence in an instant

The scorching heat around him was turning into a little bit of flame energy, which was slowly injected into Shuina's body, and almost every 2 or 3 seconds, it could increase a little bit of flame energy

Under the influence of these flame energies, Mina only felt that she was full of energy, which was not comparable to the frozen crown

It's just that the boss who came out in this environment probably wouldn't be afraid of Mina's fire-based magic

What is Mina's true? The Flame Dragon's additional skill is called "Purple Flame Skyfire", which is a very powerful fire magic, but Mina knows that he can't use such a trick unless he gets the environment out of here

Along the main entrance avenue of the palace, although Mina already knew that this palace was called "Flame King City", Mina did not know the history of this world at all, so there was no way to know the history of this palace

And when Mina actually walked into the interior of this palace, Mina found that the temperature here was much higher than that outside, as if it was absorbing all the heat around here, and Mina saw that his fire energy was rushing at 1 point per second

Bypassing the palace's large and purposeless hall, Mina came to a place that was clearly a lodging area, because there were stone gates in front of Mina

When he opened the stone door in front of him, Minai found that there was nothing in the room inside the stone door, only ashes remained, as if all the things that could be burned in this room had been burned

After that, Mina, who was not convinced, opened all the stone doors that could be opened, but all he got was ashes, and once Mina used a whirlwind technique to blow all the ashes in this room away, and as a result, he got nothing but his own disgrace

"There's nothing left, there's no corpse or anything like that, so it looks like this place has been abandoned," Mina came to the conclusion after carefully inspecting the open room

It's just that this conclusion is not what Mina wants, and here, Mina always feels a faint danger around him, as if he has entered an extremely dangerous crater, but he can't find the source of danger at all

When Mina's hand came into contact with a stone gate that was obviously extremely ornately decorated, he felt that the stone door was a little cold, and it did not match the blazing heat around him

Pushing it open, Mina felt that his eyes lit up, because he actually saw a huge bookshelf and the most strange thing for him was that this bookshelf was actually full of paper books

Moreover, on this, Mina also clearly saw a book of magic skills

However, before Mina had time to rejoice, Mina only felt a hot wind blowing behind him, and then saw the paper books rapidly aging and shattering, and finally disappeared into ashes along with the bookcase

When this otherwise cold and luxurious master room was filled with a blazing atmosphere, this room was just like the other rooms, covered with ashes

However, just as Mina was about to turn his head away in frustration, he suddenly noticed that a spot in this room suddenly flashed with a crystal point of light

After hesitating for a moment, Mina still used a whirlwind technique

And when the whirlwind blew up the ashes in this place, I saw a pure white crystal Hugh the size of a human head lying directly below the bookshelf

"Something good is finally there" Mina picked up the large crystal, then checked the properties

"Fourth-level guild cornerstone?" Mina exclaimed, he knew he had hit the jackpot this time
