The so-called "post-demon-slaying era" refers to the special period recorded in history in the half century after the end of the demon-slaying war. Compared to the Demon Slayer War known as the Dark Age, although the demon army has been driven back to their original world by the survivors of the Twelve Demon Slayer Heroes, the three continents of Olopa have not been peaceful, but because the common enemy disappeared overnight, the countries that formed the Demon Slayer Alliance, Driven by their own interests and contradictions, the alliance collapsed, and the order of the world was not restored, but instead fell into the original allies fighting each other for the greater interest of the reshuffling of the Olopa world after the Demon War, and the remnants of the demons remaining in the three continents were also making waves from time to time.

The post-demonic era was one of the most turbulent and chaotic 50 years in Olopa's history, but it also produced many legends.

In the ancient Mishura Empire, there was a young man who was born into a traditional aristocratic family. Although he was born into a family of knights, he did not inherit the good genes of his father's generation, his body was weak, he was not suitable for the cultivation of knightly skills, and he did not have any talent for learning magic, let alone any interest in politics, but he was not exactly a waste, this young man had a talent and enthusiasm far superior to others in one aspect, and that was alchemy.

His bedroom was also his real room, which was full of manuscripts, flasks, test tubes, and other alchemical instruments, and the walls were covered with equations. The theory he proposed is a milestone in the history of alchemy. At the age of 24, the Snowy Federation even sent an emissary to poach him to be a mentor in the alchemy discipline, but of course this request was rejected by his father.

The young man's knight father was a well-known general in the Mishura Empire at that time, and he was also the main person in charge of the Empire's Demon Extermination Unit. Although the demon Satan Abaddon and his subordinates who invaded Olopa have been driven back to the Demon Domain, there are still a large number of demonic remnants on the three continents of Olopa, who rely on the Force pools formed by the accumulation of the Force and scattered around the world as a base, and develop a large number of demon-believing sects among humans and orcs in an attempt to make a comeback. As a result, each country and clan has set up its own demon extermination operation unit, which specializes in clearing out the remnants of demons operating in their sphere of influence, and clearing or sealing the Force pool.

Since the young man's research project included a lot of research on demons, his father needed his skills, so he made an exception for his son, who was completely incapable of fighting, to join his army as a military researcher and use his skills to eliminate demons. It should have been a good thing for the young man, but he buried it with his own hands.

In a clean-up operation, the opponent was a high-level demon close to the strength of the demon king, and the demon extermination operation team rushed to the battle with insufficient intelligence and was ambushed...... Although the demon was still successfully eliminated in the end, the troops suffered heavy losses, and the young man's father and 500 soldiers were eroded by the demonic energy generated by the demon's self-explosion before he died, and they were in danger.

When his mortally wounded father and soldiers were carried in front of him, the young man should have used his skills to heal the wounded as usual, but instead of doing so, he became interested in the demonic erosion of humans. Over the next few days, the young man used the many victims, including his own father, as research materials and practical products for the sake of healing, eventually leading to the tragic death of his father and the other injured and turning into demons.

After the incident in the east window, the young man was arrested by the emperor ** and asked to hang. Before his execution, he did not regret what he had done, but lamented that human life was too short for him to continue his infinite research.

The soul of the dead young man becomes a lonely ghost, wandering around, pouring out his strong desire to be reborn. At this moment, the vampire elder Orlando happened to pass by and found this flowing soul. Orlando retrieves the young man's body and directs the soul back into the body, allowing the young man to regain his life in the world as a vampire.

The young man with a crazy dedication to research later became one of the most powerful Eight Sages among the Eight Sages of the Vampire Prince Dekra, symbolizing the spirit of "knowledge".

This is all the information about the man named Orome from the Lich King Callowing. That was only Orome's life before he became a vampire, and nothing else was known about this mysterious man, such as how he fought or what his weaknesses were. But the Lich King's words of reminder made Owen feel like a man: "For that Eurome, you have to deal with it." He's a research maniac, and what it means to be a vampire is simply for him to have an almost infinite amount of time to study, and as long as he thinks it's worth studying, even the vampire prince can't stop it. You, who are covered in demonic blood, be careful not to be targeted by him. ”

Now it seems that the Lich King was indeed prescient, and Euven confessed that he had been targeted by Orome.

I thought so much about it just now, and in reality, Yushi, who was guarding the blood chamber, was still fighting with several of Orom's lieutenants. But now is not the time to worry about his own safety, and Owen has not forgotten the purpose of his trip. Taking advantage of the gap between the fierce battles between the two sides, he bypassed the battlefield with flexible footwork, approaching the invisible barrier looming behind You Shi.

Yushi sensed Owen's actions, and she left the entangled Sariya sisters behind and dodged in front of Owen.

Immediately after him was the scarred James, who had already swung a machete at You Shi before his blasted body could heal.

Regardless of Yus's weak and slender body, she was never sluggish, and she jumped up with a backflip, kicking James hard in the jaw with her right heel, but James was so strong that he was not kicked away, only a few steps back. But when he stood firm and was about to lift the knife and fly up again to slash, he found that the machete was crawling with magic leeches at some point, crawling up his body along the blade.

"Boom boom boom" ...... James is once again consumed by a magical explosion.

Owen seized the opportunity, bullied forward, and swept Yushi's waist with a kick. At this time, Yushi's attention was attracted by the mirror of the Sariya sisters, and she was caught off guard by Owen with a kick in the left waist. Owen's kick was full of strength, and You Shi was kicked 5 or 6 meters away by him. You Shi, who was steady, couldn't help but be stunned, although she was attacked unprepared, but it was incredible that a human on the other side could beat her as a Blood Clan's Eight Sages! Of course, if she knew that Owen had fought with three Eight Sages before and defeated two of them, she would probably not be surprised.

Just as Owen was about to win the pursuit, an arrow swept in front of him and nailed it to the invisible barrier. "Don't meddle in your business, do what you have to do. Terry shouted to Owen, his hand was not idle, and he snapped the bowstring, and four or five arrows shot out one after the other, hitting the same place one after the other.

Even the weakened barrier finally appeared a gap: a dark red circular spatial wormhole, about half a meter in diameter, barely enough for an adult to chase into. It was no longer Owen's turn to think more, and he decisively rushed towards the spatial wormhole.

But where could Yu Shi, who is the guardian of the blood cavity, let Owen pass so easily, she raised her bare hands, and a large group of magical leeches flew towards Owen. But a mirror stopped the magic leech. "It's not that easy. Liya grimaced at Yus.

"We'll talk about it after we're done. Sally, who quietly appeared behind her, held up her mirror and returned the magic leech to its rightful owner. As Yushi fended off the twin sisters' rebounding attack, the blackened James lunged at her again, and Terry fired cold arrows at her.

Under the attack of the four people, You Shi could only watch as Owen burrowed into the spatial wormhole and invaded the blood cavity she was responsible for guarding.

couldn't stop Owen, You Shi simply slowed down. She stopped, her eyes glaring at the four people besieging her: "It's just four lieutenants, and they dare to challenge a sage." ”

"It's not just four people. Terry said.

The spatial teleportation light flashed, and two more people appeared in front of Yu Shi, who, like Terry and the other four, were also wearing uniform uniforms that symbolized the adjutant of Owenm. One of them was a tall fat man of more than three meters tall with the letter "M" on his chest, and the other was a hunchbacked old man with a cane and a white glove on his hand, on which the letter "B" was printed.

"Ahem," the old man coughed a few times, "Lord Youshi, Sir said that before that real product comes out, I must let you stay outside for a while." ”

"You're asking for your own suffering. You Shi sneered.
