The first lesson in the morning was about the history of demons and the brave. The gray-bearded history teacher www.biquge.info pen "Fun" Pavilion walked into the classroom, unfolded the textbook on the podium, and cleared his throat.

"We already know in history that the brave Li En defeated the God of Destruction in the final battle, and at the same time divided the power of the God of Destruction into four parts, and those four parts of the power were transformed into four demon kings, dividing the entire demon race into four countries and ruling separately. ”

"Teacher, hasn't the Demon King lived to the present since ancient times?"

"Not really, although the demons have a lifespan far beyond that of humans, they also age, so after the death of the demon kings of the past generations, the power of the god of destruction will be passed on to the next generation, and a new demon king will be born. ”

"In that case, will the four demon kings unite to resurrect the God of Destruction?"

"Indeed, if the four demon kings merge their powers, then the God of Destruction will indeed descend on the Demon Realm again, but there are two reasons that limit this from happening. ”

"Teacher, what are the two reasons? ”

"First of all, the four demon kings all have a quarter of the power of the god of destruction, and no one is willing to submit to the other three, that is to say, each of the four demon kings wants to become the true god of destruction, so if they want to obtain the power of the god of destruction, then it is only possible for the demon kings to kill each other and devour each other. However, for either side, those who take the initiative to start a war are easy to fall into passivity, because the emptiness of troops brought by the war can easily be used by other demon kings, so the demon kings contain each other, and no one dares to act rashly. ”

"And what about the second reason?"

"So far, there has never been a situation where four demon kings have appeared at the same time. ”

"What do you mean, teacher? ”

"When a demon king dies of old age, his country will elect a new demon king through various ceremonies, but this process is also very long, it takes almost a hundred years, and this window period seems to be deliberately set, and the four demon kings will always be absent in history. ”

"In other words, only the three demon kings contain each other, and the fourth demon king does not appear at all?"

"That's right, so even if the Demon Kings want to resurrect the God of Destruction, it's basically an impossible task without one. ”

"But teacher, isn't this demon invasion completely in line with the previous prediction of the elves? ”

"Indeed, the ancient elves used the book of Revelation to prophesy that in our time, the four demon kings will gather again, and the black flame of destruction will once again burn the entire continent. ”

"In other words, Princess Iskar's choice as the brave also confirms the prophecy of the elves?"

"I can't jump to conclusions, because it's a legend that has been handed down a long time ago. ”

"Then if we can defeat the invading demon kings this time, won't the reunion of the demon kings fail again?"

"Indeed, so it is also important for you to study here, the all-out war between humans and demons has entered a white-hot state, and you may soon go to the battlefield. ”

"As long as we follow Princess Iska, can we also become heroes who will go down in history?"

"Hehe, it's not so easy to become a hero, only the most powerful people can stand by the side of the brave, just like the brave Li En, who is accompanied by several legendary warriors. ”

"Black Sword Hime!" suddenly shouted a student in the classroom. All the students' eyes were focused on Haruka's body.

"That's right, the legend has it that you and Li En defeated the demon king hero, the Black Sword Hime. We have one here, too. The teacher also turned his gaze to Haruka.

"Well, how can I compare to the heroes of the legends. Haruka, who was originally a little drowsy, suddenly woke up, and he suddenly became the focus of the class, and he was a little overwhelmed.

"Our Miss Haruka will definitely succeed in the crusade against the Demon King with Princess Iskar in the future!" said Said, exclaiming.

"That's right! Haruka is very strong in his own right, and he has inherited the title of Black Sword Queen! Hywig followed suit.

The whole classroom instantly became commotion, and everyone was talking about Haruka.

"Alright, okay, please be quiet. The teacher tapped his hand on the blackboard, and the students fell silent. "Although it is a very glorious thing to become a hero, but the reality is very cruel, the team of the brave will always appear in the most dangerous place on the battlefield, although everyone wants to be a hero, but the mortality rate of the brave team is also the highest, and there are often not many people who can accompany the brave to the end, so if you don't have a certain strength and awareness, you still don't easily say that you want to become a person around the brave. After all, in the face of death, not everyone can have this courage. ”

The teacher's words plunged the entire classroom into a dead silence, after all, for this group of young people, the fear of death was a haze that they could not overcome.
