"I guess this is it." They came to the foot of a mountain with little vegetation and said to a path made of pale pink gravel.

"Well, that's right. Didn't my uncle say it before, there are two broken totem signs at the intersection, just go up. Miria replied, "The two stakes we just saw." ”

"That's good. The place is really stuffy enough, and ...... It's as if someone has told me before......"

"Really?"

"Hmm...... Seems to be, I can't remember it......"

As they spoke, the three of them walked along the rugged stone path to the top of the mountain.

Strange to say, the three of them walked almost halfway up the mountain, and still no one mentioned the potion. And even in such an extremely stuffy environment, the three of them still kept neatly dressed and showed no signs of messiness. To say why. Yujiali is wearing a "pseudo-Vulcan robe", which allows her to adapt to the high temperature environment to a certain extent. Because of her physique, Blala is more able to adapt to the harsh environment than ordinary people, and her outfit is very refreshing. And Miria is hindered by the relationship of image, although she is conservatively dressed and sweaty, she still endures the hot environment and maintains her image as a lady.

"I, I say......" said Miria sweating, "have you forgotten about the potion?" It's almost hot. ”

"Huh? Yes. I'm so sorry. Only then did Yujiali react, so she hurriedly took out the potion that Lao Gu gave them and distributed it to everyone.

"It's all this time, it's still so hot here. It seems that even at night or in winter, it is the same. Yugari and the others said to themselves as they drank the potion. After that, it didn't take much trouble for them to come to the top of Chiyan Mountain.

As soon as they reached the top of the mountain, Yujali and the others were shocked by the scene in front of them. A red dragon as huge as a mountain rock is lying in the volcanic rock with its eyes closed. Its huge size and majestic body made humans look incomparably small in front of it, and Yugari was shocked and speechless when they saw the dragon for the first time.

On the dragon's solid body, a large amount of black filth was constantly wriggling, slowly volatilizing a faint black dust into the surrounding heat wave. Underneath it, churning lava scorched her massive body, and the black filth dissolved by the lava immediately corroded the flowing lava and the surrounding soil.

I don't know how long it took, but Yugari and the others finally recovered from their shock.

"I—I think that's the culprit of the plague." Miria said, pointing to the black dirt that was constantly scattered on the dragon's body.

"I should." Yugari chimed in.

"But I think it's impossible to get rid of it, no, even if it's just trying to get rid of it."

"That's right." Yugari frowned and nodded in agreement, "Then we can only find a way to purify all those black filths." It seems that if we wait for the lava to dissolve them all into the soil river, the scale of the plague may increase. ”

"Can you purify it?" Miria asked.

"This ......," said Yugari, sweating, "seems to ...... Give it a try......"

As she spoke, Yugari chanted a spell, "Divine Advanced Purification Technique!" With the casting of the spell, a huge circle of divine aura flashed at the dragon's feet, and the divine light suddenly illuminated the dragon's entire body. However, as the divine light receded, the black filth still attached to the dragon's body, showing no sign of abating.

"Good...... It doesn't seem to work. "I think I'm not level enough to dispel more powerful effects." ”

At this moment, as if sensing Yujiali's purification spell, the dragon slowly opened its eyes. The huge crimson eyes stared straight at Yugari and them in the distance, which suddenly made Yujiali and them tremble.

"She, she...... It seems to be awake, yes......" Yugari said with a shudder.

"How, what to do...... Retreat first......" Miria said, but her legs had long since stopped listening to her.

However, the dragon did not react, just glanced at them, closed his eyes again, and went back to rest.

"Whew...... Scared the hell out of me. After a while, seeing that the dragon was not moving, Yugari let out a sigh of relief.

"I thought I was going to die."

"Is there any way to do it now?"

"This ......," said Miria embarrassed, "I don't have anything to do. What can we do with such a behemoth? You can't beat it, and you can't drive it away. We can't deal with the filth on it, we don't know anything about it! …… That's right! Why don't we take some samples back and ask my uncle, and let him study and see what elixir can cure these filths? ”

"It's a good note." Yujiali agreed and said, "Then let's be careful and don't wake it up." ”

So, against the tumbling heat, they walked with difficulty towards the dragon's side. Still some distance away from the dragon, Yugari suddenly noticed that a faint layer of dark spots was gradually beginning to attach to everyone's skin.

"Not good!" Yugari shouted in her heart, and she immediately cast a spell to teleport everyone back to where they had been.

"What's wrong?" Miria, who still didn't understand the situation, asked puzzled.

"If you get too close to it, you'll be eroded by the black filth. Look at the dark spots on your body. With that, Yugari hurriedly chanted a purification spell to remove the dark spots on everyone's body. Fortunately, it was found in time, and if it was completely infected, it was estimated that it would not be able to be purified. ”

"Then we won't be able to get close to it." Miria frowned and asked, "Can your shield spell be resisted?" ”

"Probably not. My shield spell can negate the damage of erosion, but it can't stop it from spreading and other negative effects. If I teleport over all of a sudden, I teleport back right away......"

"That's dangerous, too, the closer you get to it, the faster it should infect. Who knows if it will be completely infected when it comes to it. I think it's dangerous even for a few seconds. ”

"That'...... I really can't think of anything I can do......" Yugari said in frustration.

"Well...... "Wait, the reason why the dragon is here is probably to heal the filth on his body through lava. In other words, if lava can dissolve the filth, we can also protect ourselves from erosion by means of high temperatures." Thinking of this, Miria said with fighting spirit, "I have a good idea to try." ”

"What? Say it. ”

"I think since the lava can wash away the filth from the dragon, the same heat should at least temporarily withstand the filth. If that's the case......" Miria looked at Brala and continued, "Blala, don't you have the skills to keep yourself in flames?" If you stay that way, can you go to the dragon? ”

"In flames?" Brala said blankly as she dragged her lips with her fingers and looked at the sky.

"It's the state of Qi before you cast the special kill!"

"That." Blala said expressionlessly, "But those energies must be cast or canceled immediately, and if you keep it up, it will backfire." ”

"If only I could keep it!" Miria then said to Eugari, "Gilly, you can put a mana shield on Bralla and absorb the damage of the backlash, so that she can keep the effect of the fire until she walks to the dragon." ”

"The energy of the backlash is huge. It's much more energy than it can be released. Bralla added.

"Peace of mind. I've long since discovered that Jiali's mana is amazing. Normally, after a few large healing spells, ordinary priests are already exhausted. In such a long time, I haven't seen Jiali tired after a fight. Right? ”

"Hahaha...... "Yujali said embarrassedly, "it's not that good." But don't worry. I'm still confident in mana. And, even if I really can't hold it anymore, I'll teleport you back before you get hurt. ”

"Still have questions?" Miria asked, looking at Brala.

"Not at all!" Blala said with a gesture.

"Okay, let's try it first." Miria said energetically.

So, Blala immediately began to prepare the skills. I saw that her expression was serious, and she gathered all her strength, and then, a layer of blazing flames instantly surrounded her. At the same time as the flames were generated, Blana also carried her battle axe and hurried towards the dragon. Eugari danced her staff, a faint halo of divine light at all times, shielding her from the flames.

Against the tumbling heat, Brala rushed to the dragon with difficulty. She raised her tomahawk, pinpointed a piece of black filth, quickly chopped it off, and immediately loaded it into a container in the magical space. At this moment, a divine light immediately flashed under Brala's feet, and in an instant she was teleported back to Yugari and the others.

"How? No problem. Eucaria immediately checked for Bella, who had extinguished the flames.

"Hmm. No problem! Successful completion of the task. Bralla took out the container and held it up to Eugaria. The filth in the container was trapped inside, emitting a faint black smoke on a continuous basis.

"Alright. Let's go. We'll have to go back and ask Uncle about them. With that, Miria urged everyone to hurry down the hill, and before the potion wore off, she turned on her horse and returned to Sunset.

The next morning, when Yugari and the others came out of the guest room and walked into the living room, they saw the old Gu and them sitting at the square table fiddling with the potion.

"How? Any good news? Yugari asked impatiently.

"Good morning, girls." Lao Gu said hello as he continued, "It's barely good news. I've studied the samples you brought back. It's a very potent infective. The exact source has not yet been investigated, but most of the features have been figured out. ”

"Is there any cure?" Yugari continued to ask.

"There is a way, but it's just ......," Lao Gu frowned, and replied with some embarrassment, "It's just that the materials for making potions are hard to get." ”

"What material? We can do what we want to do and collect it. ”

"Well...... old Gu looked at the energetic Yujiali and said embarrassedly, "In addition to some necessary auxiliary materials that can be bought in the market, there are three main materials that are difficult to obtain. A type called lava fruit, with the property that it can melt and decompose at ultra-high temperatures, can eliminate the extremely efficient propagation ability present in the sample, greatly reducing its harm. However, the fruit has a short shelf life after it is harvested, only one day at most. So there is basically nothing to sell in the market. Some stores can be ordered by appointment, but the price is really ......"

"So, where can I find this lava fruit?"

"What's the nearest place...... Actually, there are lava caves at the foot of Mt. Chiyan. However, it is inhabited by a creature called a rockfire insect. Resembling a giant centipede, it is both ferocious and dangerous. Many adventurers have been in it before, but most of them never came out alive. So after that, it was basically rarely mentioned again. It is said that the strength of a Rockfire Insect can rival that of a good adventurer, not to mention that there are many of these guys there, so it is almost impossible to collect Lava Fruit without gathering a team. ”

"That's right. Got it. Yugari nodded and continued, "What about the other materials?" ”

"The second material is not very difficult to find, but it is so far away that even if it can be found on the market, the price is ridiculously high. It is a material that grows on the northern continent and is called the Frost Fruit. Its low temperature is mainly used to freeze the activity of the sample, and then to achieve the effect of making it impossible to reproduce. However, it takes dozens of days to go back and forth from here to the Northern Continent, and I don't seem to have seen it in the market recently. So it's more difficult to do. ”

"Frost Fruit?" Eucaria said to Miria, "That's what Blala bought in Treasure Bay before, right?" That's great, and it comes in handy! ”

"Hmm!" Miria happily replied, "Wait...... Anyway, you haven't eaten it all......" Miria squinted at Brala.

"No, I don't. Because it's so unpalatable. It's very icy. If you eat a little more, your stomach will hurt. Blala replied unhappily.

"That's great." Yugari squinted and smiled, "So, what about the last one?" ”

"The last one...... Everyone calls it the pseudo-sacred fruit. It is necessary to finally disperse the source of the occurrence. As for the way to get it...... Old Gu scratched his head and said, "This fruit is very special, and generally speaking, there are two ways to get it. It is specially cultivated in the temples of large cities because of its wide range of uses. Because of this, temples are generally not sold, so it is difficult for ordinary people to get them. The other is obtained by purifying the Devil Fruit. ”

"Devil Fruit......" Miria muttered with a worried expression.

"What? Miria, you know what? Yugari urged.

"Hmm...... I know a little bit about it. It is said to be a fruit that contains a little evil energy. People with low mental strength will unconsciously want to do bad things when they eat it. However, because the effect doesn't last long, and it's all mischievous behavior, it's not particularly dangerous. But...... Very hard to find indeed. ”

"Don't you know where?"

"Hmm...... This fruit is a bit of a stranger. When the seedlings are young, they will cling to other plants to grow, constantly absorbing the nutrients of the host, until the host dies, and it is exactly the same as the host, which is difficult to distinguish. That's why many times people eat it by mistake and do a lot of unbelievable things. Ripe Devil Fruits are said to continue to wander in a certain form, sowing seedlings. But no one has ever seen what it looks like. ”

"That is to say, the appearance is similar to the fruit of other plants, and I don't know where it comes from?"

"Well, that's what it means."

"This is embarrassing...... "Yujiali thought for a while, and then suddenly said, "Wait, Sister Luqi seems to have said before, when Konya took her to the Revolutionary Army laboratory, she seemed to have found it, it was the one in the East Vigil Forest." I think I can ask Sister Luqi. ”

"That's great." Miria suggested, "So be it. I went with Brala to the lava cave to collect the lava fruits. You take the flying mount back to Starlis. Good no good? ”

"Hmm...... I'm fine. But, you two go ......."

"No problem! Rest assured. Miria said firmly.

"Then we'll go to the market and prepare other materials." Gu Yiyuan also said energetically.

"That's right. Do you still have the potion that was given to you before? Take some more with you. It seems that the temperature in the lava cave is not low. Lao Gu asked as he took out the potion.

"That's right. It's very hot around there, it's just hot. Miria grumbled unhappily.

"This is a burn potion, so bring it with you. In case you accidentally get burned by a bug and don't recover your profession, with this treatment, the effect is very good. Lao Gu continued.

"That'...... Thanks. Miria whispered embarrassedly.

Yujali, who was ready, said goodbye to everyone and went out. She boarded the magic unicorn and instantly soared into the sky, and in a short time flew out of Sunset Town and disappeared from everyone's sight.

"Okay, so powerful...... Gu Yiyuan looked at the sky blankly, and couldn't help but admire.

"We're on our way, too." After Eugari left, Miria, who hurriedly packed up the potion, was not to be outdone, and beckoned Brala to run in the direction of the lava cave.

"Strange...... I think I've seen the ingredients of this sample somewhere before...... I can't remember who came for a while...... 'After they left, Lao Gu frowned and thought about it.

"What's wrong? Can I help you? Gu Yiyuan saw his father's frowning look and couldn't help asking.

"Uh, no...... It's nothing. I'm older, and I can't remember a lot of things. Lao Gu said in a hurry.
