Demon Lord's Reincarnation

It took Luke two whole days to finally accept what has happened to him. In the beginning, he thought he was having a very long dream that was happening before his death, actually, he still was thinking that was what's happening, but now he had a different view. Be it a reality or a dream, this was his chance to change things to what he wants. This was his chance to face destiny and control his fate. 

The first thing he needed to do to control his fate was get more power, and more influence. The demons weren't going to do anything for the next three years. Within those three years, something would trigger the demons and would later spark the war. As a nobody, Luke wasn't privy to any information about why the demons started their invasion. Of course many voiced that the demons attacked simply because they were demons. But of course, there were also other voices saying it was a certain human's fault.

Either way no matter the reason the demons would attack in the end. It wasn't really a secret that the most powerful demon lord loves battle, he lives and breaths it. If at some point in the future he gets bored he would attack the humans just for a good battle.

Even if by some miracle the demons don't attack, the humans will. Even after failing twice, human greed wouldn't disappear. The humans would once again attack the demons at some point in time and of course, the demons would retaliate. 

Even if Luke gains enough influence he could only stall the inevitable. He didn't really have anything against the demons, but he wanted to protect those important to him. He could run away from all of this and head to somewhere remote but knowing the future he saw, there was no place the hands of the demons won't reach. 

So the only way those important to him will be able to survive and be happy is if he pushes the demons back to their lands. He must show them how to fear the human race. To do this Luke needed to eliminate three specific demons. 

The one on the top of his kill list would be the demon that started this all. The strongest Demon Lord, Kretos. Because of his elimination of the former demons lords, the dumb king of the Sliral Kingdom thought he could somehow take what wasn't his. After the King of the Sliral Kingdom, the other human kingdoms also thought they could take a bite as long as they had more power, but that proved to be the most idiotic decision ever. 

In the future, Kretos never appeared in the Great Demon Invasion. It might because there was no one worthy to fight. Still, to stop the demons from ever thinking of attacking, Luke needed to eliminate their greatest support which was Kretos. Of course, he was not going to do that immediately, he first needs to find a way to get strong enough to kill Kretos. 

The next problem was Namor, the Demon General that controls the mighty undead army. Namor and his army would later decimate several kingdoms within the span of a few months. Because his undead army was such a threat, the humans created a new weapon called 'Holy Cannons' which can only be powered by those battle priests from the Temples of Gods and Goddesses. 

The Holy Cannons were derived from an ancient human weapon called Mana Cannons. Unlike the Holy Cannons that needed the faith of the battle priests to activate, the Mana Cannons could be used by anyone as long as they had enough mana supply. 

These two weapons became instrumental in stopping the demons' advances, but that would be four years later, a year after the initial attack of the demons. The Mana Cannon showed its might at the beginning of the invasion, but the more effective Holy Cannons would be made a year later. 

Now the last person on the kill list and also the weakest one on the kill list was the former demon lord, Demonic Fox Tsukiko. She was the one who led the first wave of demons to attack the Humans.

Even though she was considered weaker than Kretos and Namor, it doesn't mean she wasn't strong. No quite the opposite, Tsukiko was like a storm on the battlefield. Her powerful and devastating large area spells could easily wreck any army that stood in her way. Not only that, the army she commanded consisted of Onis and Vampire Lords. 

She alone was already a huge threat but with an army of Onis, and several Vampire Lords under her command she became nearly unstoppable. 

These three demons were at the top of the food chain in the demon lands, if they were to fall the others would fold. Without the three of them to lead, the demons would be forced to retreat. 

'Alright I have the path to take but how to get there? I need power, overwhelming power that could match up to these three demons, but how do I get it?' Every time Luke was formulating his plan on how to stop the Great Demon Invasion, he would always get stuck when he tries to think of a way to get enough power to win. 

'The best-known way to gain power is if I become a hero of one of the Temples. But Kretos has already defeated a hero from a Temple. Though I have the advantage of knowing the future's advanced military training to enhance one's mana and physical strength, that wouldn't help much. Even if I train now continuously for the next five years, I won't even reach the level of Tsukiko power.'

Luke who was in his room sitting on a chair near the window looked out and saw the moon. The night sky was beautiful today as not only was the moon full tonight, but there were also a lot of stars accompanying it. 

It was so different from that time he died when there were nothing and no one there with him. Not even the stars were out that night... Like a bolt of lighting an idea flashed in Luke's mind. 

'Why am I thinking I should do this all by myself? I can train others, I can teach them the advanced military training that will be invented five years from now. If we start now, before the war begins will be stronger than most soldiers. Heck if I can even find those famous powerful people that would become famous later, and teach them these training techniques then they can get stronger faster as well. Also since I know most of the tactics Namor and Tsukiko used I can lead them to score some victories here and there.' 

Luke was getting excited when he got the thought. This plan of his might actually work, the more he thought about it the more excited he became. 

'Still, will that be enough?' 

Luke then remembered his last battle were he faced the army of the Demonic Fox Tsukiko. Before that neverending torrent of spells, the Vanguard was helpless. He was the only one who remained until the end as his comrades retreated. Even as the Onis assaulted him he stood firm, trying to buy more time for his companions to retreat. 

That was when he met her on the battlefield. Her Golden Hair shined brightly under the starless sky, her seven tails elegantly followed her every movement. Even though there was no denying that she was a great beauty only fear came to those who saw her. This was the Demonic Fox Tsukiko, the former demon lord. 

She with one spell had changed the landscape, Luke stood no chance whatsoever, as he could only dodge. Still, even though he was outmatched Luke stood tall and faced her with all his might. As he was defeated he remembered that line Tsukiko said to him. 

"What does he usually say at a time like this?... Oh right, thanks for the battle."

Those were the last words he heard from her as she and all the other demons left him there to die. After reminiscing, Luke renewed his resolve and promised not to die alone in a place like that.

'First I need to improve my own personal power a bit. Second I should recruit others to my cause. Third, I need to find the genius that created the Holy Cannon. If the Holy Cannon is created ahead of time, then when the demons first strike the losses would be lowered. Fourth, I need to find a way to gain even more power, I need to research if there is a weapon or a spell from the ancient humans that could help me. If they can create something like the Mana Canon then they might have created a more powerful weapon that could fight the Demon Lord. Then Finally I need to face the three powerful demons starting with Demonic Fox Tsukiko.'

Now that Luke had formulated his plan he felt like the fog of fate was becoming a bit clearer.
