New life in another world

Evil Dragon

In an completely isolated world,there lived an evil god who liked to eat delicacies, he used to demand delicacies from surrounding kingdoms as compensation for not bringing any harm to them. He used to like the crunchy "cookies" made by cookie kingdom so much that the evil god was nicknamed "The Cookie Lord" by surrounding kingdoms but the Evil God did not care about such trivial things,The evil god was none other then a humongous dragon which breathes fire hot enough to melt away stars. The evil dragon had won many battles before he came to be known as "Evil God", he had great abilities and boosts in his arsenal, he destroyed kingdoms and villages if not being compensated, it used to kill women,kids,male everyone without mercy.
One day the mighty dragon was strolling around collecting it's weekly compensation, he was happily munching on the cookies that these kingdom inhabitants created but something was wrong.... thought the evil dragon but after a thought he didn't cared about it and thought it was just his imagination.

{Kingdom of bravery}
An secret room where 6 people were sitting on a round table, someone with red hat spoke up, "so,for how much time we need to endure this??!!??" Another person with green coat spoke up, " the ceremony for summoning has ended 2 days ago and still the hero hasn't arrived?". The one who was silent till now spoke up, he had a crown on his head with a red cape behind him, "the magicians have reported that it won't take much time, we just have to wait a little...."
On this am iron clad armored guy spoke up, "FOR how long do we feed him? We are the people of kingdom of bravery and here we all are acting like cowards!! What's the point of this? Aren't we royal knights and magician enough to kill it?"
The guy who was drinking tea while listening to them finally spoke up, "I suppose the knight general isn't speaking anything wrong but don't forget the incident of "Blue flame war"." Everyone went silent after hearing it, the knight general spoke up again, "how could someone forget about that nightmarish war, the kingdom of savage, kingdom of weapons and kingdom of warrior made an alliance to oppose the dragon, the preparation for the war took them atleast 8 days and all was for nothing....after knowing the thier plan, the dragon breathed strange kind of flame upon them, its color was blue, everyone got wrapped in that flame, people tried to extinguise it but they couldn't because the flame was burning no matter what, they tried all means of putting the flames out and everyone started to burn away leaving nothing, all the three kingdoms were the size of 150 million kilometa each kingdom covering 50 million kilometa and all became nothing with just one breath of that dragon. I guess that's why we need someone with otherworldly powers to defeat that dragon...."
*TING tingling TingTing*
Hearing these bells sound everyone got alarmed and were starting to have hope for what was about to come, these bells sounds were coming from a particular hall called "Summoning chamber" to indicate someone came out of it. Everyone in the kingdom of bravery started to gather around the summoning chamber to see thier savior who will save them from this dreadful dragon. The summoning chamber hall started to tremble and thus opened the gate,from the darkness inside the gate 2 silky white hands came out opening the gate wider, a man stood there in black suit which was completely strange and new for this world, he had a long katana in his waist. After combing his hair with his hands he spoke up, "So, what y'all want?" He was looking cool saying that then one of the man who was watching him said, he had crown over his, looking at him everyone lightly bowed down to pay the respect, the one with crown over his was none other then king of the kingdom of bravery.
"We summoned the great hero to save our world from this dreadful nightmare, if you agree upon our request we shall award you with rewards."
With bored face the man standing walked outside the gates and strated to walk towards west direction while saying
"Ya ya whatever just prepare the reward for me i will come back after defeating that guy over there."
Everyone were starting to have more hope then ever, finally the nightmarish dragon which threatened everyone was about to die!
In the raining night, the hero was walking to particular direction sensing a massive aura, his lips bent into a grin finally meeting a worthy opponent, this hero was summoned in many other different worlds with thier own different reasons but none could even fight this young hero's full power. Now that he has found someone with that huge aura, he can finally go all out.
