Why is it ......

In the ancient library in the mountains of Kunwu Mountain, Sister Yu stood there speechless for a long time, the dim light shining on the walls of the wall, and the scenes painted on it......

Everywhere there were dead bodies, figures falling from the clouds, corpses piled up on the ground;

Blood stained the firmament, the sun faded, and the stars seemed to fall;

The frescoes on the walls are untainted with dust and appear to have been wiped down frequently, while the entire mural depicts the end of the First World War. Pen "Fun" Pavilion www.biquge.info

The back, standing between heaven and earth, seemed to be very small and huge, obviously wearing the costume of a scholar, and the hairband was fluttering in the wind...... But the long sword in his hand pierced the neck of an old man.

The old man was roaring and roaring, and it seemed that the next moment his body would explode, and he would die with the owner of this back......

"Who is he?"

Sister Yu suddenly turned around and looked at the old man in the library pavilion, "Who is the person in this painting? What happened to this, and what happened later?"

"Are you asking about the besieged, or about the besiegers?" the old man seemed to be interested, and walked back from the side with a smile, "This is the darkest era in the history of demon slayers, and there are many causes and consequences. ”

"Tell me all......" Sister Yu clenched her fists.

This back in the painting, she has seen it!

Seen in the town, seen in the city of color...... Although both times were glimpses and not real, Sister Yu knew that she must have seen it.

This is the amazing sixth sense of the legendary woman.

The old man smiled angrily, "Girl, you are finally willing to listen to the third grandfather's story, hahahaha! Come, sit down, I'll tell you a good story." Don't always look at this painting, otherwise it will affect your strength cultivation. ”

The third grandfather turned off the wall lamp here, sat on the rattan chair, took a sip of tea from the purple clay pot, and put the scroll in his hand aside.

The corners of Sister Yu's mouth twitched, but she was patient and impatient, listening to the old man talk about the cause and effect.

"Let's say that two thousand years ago, there was a big demon in the water who did evil in the world, and that big demon was actually originally a demon exterminator who practiced in the mountains, and he was free from the world, leisurely, and strong. But when he returned from a visit to a friend, he found that his wife had been abused to death by robbers, and that his infant baby had been devoured by a wolf...... In short, it's miserable. ”

Sister Yu unconsciously listened a little intrigued.

The demon slayer was furious and went to seek revenge, but he never expected that because of the troubled times at that time, those robbers had already raised troops and gathered tens of thousands of troops.

Originally, these ordinary soldiers could not stop a powerful demon slayer, but at that time, there was a powerful demon slayer organization that used the army gathered by those robbers as a pawn to plot against the world, and stopped the demon slayer from killing the demon slayer.

This demon slayer was resentful in his heart, and the hatred in his heart resonated with the demon world, and the place of death happened to be an ancient battlefield between the original human world and the demon world......

Therefore, the demon slayer who was originally a reclusive demon turned into a powerful demon who wanted to destroy all demon slayers, causing trouble in the human main plane, and finally arousing the all-out encirclement and suppression of the demon slayer organization......

"Later, that guy fled into the demon world and took it for two or three hundred years," Sister Yu's third master sighed, "I never expected that the other party would endure and accumulate strength, and finally become the king of the demon world; ”

At that time, there were many masters in the main plane of the human race, and the demon slayer was passed down from ancient times, and there were countless masters;

Sister Yu pouted: "Is that demon king the person in the painting?"

"No, that's the master of the person in the painting," the third master shook his head and said with a wry smile, "Grievances and grievances were completely impossible to let go of at that time." ”

In order to take revenge on the old demon king, the demon master gathered almost all the masters of the demon master school, and then entered the demon world, fought bloodily for half a month, and killed the old demon king outside the demon king's palace.

"At that time, if those masters rushed into the Demon King's Palace, they would kill the little demon who was hidden by the old Demon King...... There's nothing to be said about it. ”

The third grandfather tapped his fingers on the armrest of the recliner, "Speaking of that little demon, in fact, it also has a lot of origins, but the old demon king has not yet become a climate after his death...... These are not just recorded in books, but also passed down orally by people like me, and they are not necessarily true, many of them are speculation. ”

Sister Yu nodded, leaned on the bookshelf, and listened quietly.

"That little demon, after the truce, the old demon king brought him to the demon world in the human main plane, it is estimated that the old demon king feels that this young man has the same experience as himself. ”

"What happened?"

"The fiancée of the childhood sweetheart and his family died in the looting of a border army, and the returning teenager fell directly into the demon in a fit of rage, and washed the barracks of hundreds of thousands of troops in blood overnight. ”

Sister Yu suddenly took a cool breath, "Can a fallen demon have such a strong force?"

"There should be, you will understand the story after listening to me," the third grandfather sighed, "The old demon king found him before the demon slayer, took him back to the demon world, taught, cared for him, and had the grace of knowing and recreating him......;

What happened later was actually very clear.

The little demon left the Demon King Hall after the death of the old demon king, wandering in the demon world, fighting, and looking for a way to become stronger.

From being unknown, to challenging one master after another in the demon world, the reputation has been passed to the human main plane; when no one in the demon world is the opponent of this little demon, the little demon has become the demon king of the demon world.

But this time, the little demon did not start a war, but embarked on the road of revenge alone.

One after another, the demon exterminator organization was attacked, and those human masters who had conquered the demon world and besieged the old demon net died one after another in the hands of the little demon.

The demon exterminators immediately organized masters to encircle and suppress, and there were more than a dozen battles in succession, and the little demon was covered in injuries, but the more he fought, the stronger he became, countless masters died in his hands, and the vitality of the human main plane was greatly injured.

It took two months for the little demon to travel all over the world, killing all the demon exterminators who besieged and killed the old demon king back then, and also left huge hidden dangers.

"What hidden dangers?" Sister Yu asked in a low voice.

The old man took a sip of tea and sighed: "Hatred has always been a thing. Those masters who returned from the demon world are all heroes and veterans, and they were killed by that little demon, how can the demon slayer organization give up?"

Sister Yu nodded and looked at the wall.

"But the demon slayer never expected that the little demon would reach the legendary strength in a short period of time...... They worked hard and spent decades building a disgraceful strategy, and the little demon used this time to complete the transformation of his own power...... So, there is the picture in this mural. ”

"What is a dishonorable stratagem?"

The old man's words suddenly stopped, sighed, closed his eyes and shook his head.

Sister Yu: "Tell me! Otherwise, I'll go to the third grandmother to complain, saying that you have nothing to do when you're on duty here, and always read the little yellow book!"

“…… Okay, but don't tell anyone else, especially not the young master. ”

"Well, you can say it quickly!"
