The giant rock mantis was face to face with Team Dora, while, surprised and still dismayed at having obtained that information from the generals, they looked at the giant monster.

-That thing is going to crush us!- Suneo shouts scared

Doraemon sees the boss text box saying "Rock Mantis, Rank F. Level 12. Earth."

-Don't worry guys, if we organize ourselves we can defeat him, if we eliminate him together we will gain experience! Cheer up, we can do it! -Doraemon says while he uses the capcopter and, flying, confronts the mantis with his staff.

-Wow, what the talking wolf said really bothered him!- Suneo says, startled.

-Of course, those evil people laughed while they boasted that they were going to continue mistreating Nobita! That's cruel! I'll help Doraemon!- Shizuka says, taking her cleric orb and running to help.

-Those guys are really going to pay us for saying those things! I admit that I annoy and beat Nobita in our world, but at least I want to free him from those ruffians!-Says Giant as he runs

-But...- Suneo says hesitantly -Ugh, I don't want to die or have my house invaded! And I'm also worried about Nobita, so I'm going anyway!-

The 4 run to defeat the mantis, and with scenes of clashes of powers and blows. Doraemon gives it one last blow with a powerful gust of wind that hits the mantis right in the eyes, causing it to fall into pieces on the ground.

-Finally, it took us a long time- Doraemon falls slowly since he ran out of mana like the rest who were resting.

-I don't feel my life- says Giant lying on the ground

-That's because you spent mana on attack spells like crazy, you have to know how to save it- says Suneo sitting on the ground.

Shizuka takes out some bottles of mana potion from her butterfly bag and distributes them to the boys -But we were able to defeat the dungeon boss and become stronger-

Shizuka, Gigante and Suneo were now level 10 and Doraemon was level 12.

-And as expected there is no dungeon reward, although we can sell the parts and magic stones of the monsters we get, I don't want to sleep in the forest because we don't have money- Suneo says sighing.

Doraemon searches in his pocket and manages to take out the "Air Cannon" for leveling up, and sighs in frustration.

-If this had come out sooner, it would have been perfect- Says the robot cat while he puts the cannon away again.

-Poor Nobita, the Demon King's generals are torturing him and for now we can't do anything to save him- Says the girl with the pigtails sad for her friend.

-What Rioku said about hurting Nobita so that he can hear him cry really bothered me, seriously- says the blue cat angrily and remains thoughtful -But I'm also worried about the fact that they are also thinking about invading our world. And what relationship does Nobita have with that? Now we go from an amulet to a key, the more I try to understand this world, the more questions invade my mind-

The cat stares at the ceiling of the dungeon and notices something curious: A drawing of wings in the shape of a DNA curve, that was the seal of the wind element.

-And how could you be amazed by that ninja girl who teased us?!- Giant claims while Doraemon uses his capcopter to go up to the roof and examine the drawing

-Hey, Sanyo was pretty, don't blame me because I was the only one who noticed it, if she wasn't evil I would take her to dinner in France and buy her a designer dress!- Suneo says blushing and indignant crossing his arms.

Shizuka notices that Doraemon was on the ceiling looking at the drawing.

-What are you doing Doraemon?- Asks the girl with the pigtails.

-This drawing wasn't here when we arrived, it's the seal of the wind element, apparently it only appeared when we defeated the mantis. Although in the guild they didn't mention anything about a drawing when defeating the boss of the dungeon- Says Doraemon analyzing the drawing

Out of curiosity, he takes out his staff and with it creates a small gust of wind towards the seal. Nothing was happening and Doraemon was going to leave it there, but the dungeon shakes again.

-D-don't tell me we're going to fight that mantis again!- Giant says as he and Suneo quickly stand up.

-Guys, the ground is opening!-

Shizuka says that as he points out how a large circular entrance opens and a set of stairs is shown, Doraemon slowly goes down to the ground and puts the capcopter away.

-Well, it seems that there is something waiting for us- says the blue robot while smiling.

The boys go down the stairs and arrive at what seemed like a beautiful white sanctuary, in the center there was something floating: A beautiful sapphire colored staff, at the tip there were golden wings that rose upwards and formed a circle whose center was floating a sphere that changes between light blue and white.

-This is a very beautiful shrine, and look at the most beautiful staff floating there on that enormous drawing of the seal- Shizuka says fascinated by the setting.

Doraemon slowly approaches the staff along with the guys. Suddenly the blue cat hears a sweet voice saying "Take me."

-Did you guys say something?- Says the blue cat.

-I didn't say anything- Giant says

-Neither do I- says Suneo.

Shizuka shakes her head -I haven't been either-

-So...- Doraemon sees the staff and hears the voice saying "Take me."

The blue cat decides to pay attention, and carefully takes the staff in his hands, which shines from its center with an intense light blue color. After that, Doraemon removed the staff from its place without problem. Doraemon analyzed it

/Staff of Aeolos. Wind. Unlimited SS rank./

-Wow, this is an unlimited item, it means that even if you are F rank you will be able to handle it. I think that is a special staff- says Doraemon, looking at his new acquisition.

At that moment, a hologram appears where the staff was, a barefoot young woman of great beauty and very beautiful hair, this was a peculiar dark blue with white glitter as if they were stars, she had a white dress and blue eyes, she also had a golden tiara with 7 crystals of different colors

-Who is she?- Suneo says curiously.

-I don't know.- Doraemon says while he narrows her eyes. -But for some reason, her physique seems familiar to me, but not with that look that makes her look like a goddess-

-My name is Ruya, the goddess of the planet Bessekai. If you are seeing this, I will have already disappeared from this earthly world- The woman says and everyone is surprised.

-RUYA?! Isn't that the name of the goddess of this world?!- Suneo exclaims nervously. -When I read the story of this to sleep yesterday, according to that, the Goddess Ruya was the one who gave the power of mana and magic to this world and left the underworld after the first 100 Years War, but the cathedrals venerate her very much-

-Ruya?- Doraemon says and remains thoughtful -Why does that name sound familiar to me? It's as if she had already heard it on Earth in another way but... I don't understand.-

-If the elemental weapons are reappearing, it means that the 100 Years War will return and the Demon King will try to conquer Illumia. If you are the new hero you are close to completing the task of rearming the sword, since you have the Elemental Weapon in your hands-

Everyone screams in amazement, it was one of the legendary weapons from the legend of Illumia that Doraemon had in his hands.

-If you aren't the new hero and you found the Staff of Aeolos, it must be that you are the guardian of the wind selected by the elemental weapons, only the guardians and the new hero can find the elemental weapons, and only the guardians can be able to rearm the Mystic Sword so that the new hero can defeat the Demon King. So guardian, protect it with your life until that time- Mentions the goddess as she disappears.

-So Doraemon is the Elemental Guardian of the Wind- Shizuka says while the three of them turn to look at the blue cat.

-W-w-wow, of all the things I could find, and it had to be one of the legendary weapons- Doraemon says stunned. -And now I'm an elemental guardian. How many things will we have to tell Princess Lillie after this. Anyway, we can only do that for now.- The blue robot guards the staff.

-Anyway, let's go back to Ningen, this day has been full of emotions- says Suneo.

Shizuka, Giant and Suneo go up the stairs and Doraemon was going to do the same, but he sees something peculiar on one of the columns of the shrine.

Doraemon takes the object, it appeared to be an illuminated blue-edged notebook, something very curious in a medieval fantasy world

-Mmmm...- Doraemon looks at the notebook -ISEKAI Project?-
