Axel's PoV:
I went to defeat the fire lions and fire lion kings next since it would be troublesome for them to evaporate all of the water in the moat.
Since the fire lions and fire lion kings were covered in flames, so whenever they fell into the moat, the water in the moat evaporated due to the flames on their bodies.
I quickly eliminated all of the fire lions and fire lion kings by drowning them inside water spheres that I had conjured using my water magic.
After eliminating all of the fire lions and fire lion kings, all that was left in the stampede were the forest slimes and forest slime kings.
The pit trap that I had prepared wasn't that effective against the forest slime and forest slime king due to their sticky slime.
When a forest slime or a forest slime king fell into the bottom of the pit and came in contact with the sharp earth spikes, they wouldn't be pierced by the earth spikes and only be stuck at the tip of the earth spikes.
Afterward, the forest slime and forest slime king would be able to escape the pit trap by creating sticky webs to propel themselves out of the pit trap.
Therefore, the pit trap was not effective against the forest slime and forest slime king so I had to manually kill the forest slime and forest slime king.
I conjured multiple wooden spikes from the nearby trees using nature magic.
I manipulated the wooden spikes to attack the forest slimes and forest slime kings by thrusting the wooden spikes into their slime bodies while aiming at their cores.
The wooden spikes attack wasn't that much of success due to the sticky slime from the body of the forest slime and forest slime kings that prevented the wooden spikes from thrusting further into their bodies.
Even if I added much more force into the wooden spikes, it wouldn't budge but instead break due to too much pressure applied to the wooden spikes.
I tried another alternative by creating water using my mana and manipulating it into water bullets.
I shot multiple water bullets into the forest slime and forest slime king with twice the speed of a sniper.
The velocity of the water bullets was too fast for the forest slime and forest slime king to notice so it was able to easily penetrate their body.
Some of the water bullets missed hitting the core of the forest slime and forest slime king but most of the water bullets were able to hit and destroy the core.
Only a few of the forest slime and forest slime king were left and none of the high-level monsters were even able to damage the protective array.
"It's time to put an end to this."
I gathered the mana in the surroundings and focused and concentrated the gathered mana into an orb.
I then draw the stored and concentrated power in the mana orb and created a beam of mana.
I aimed the beam of mana towards the remaining forest slimes and forest slime kings which obliterated them in the process.
Since I had destroyed all of the forest slime and forest slime king's bodies, they weren't able to regenerate their body.
Also, the core was destroyed in the process so my plan worked perfectly.
The high-level monster stampede ended earlier than I had thought. It must be because of me being too overpowered.
It must also be because of me meeting many powerful opponents at such an early-round including the fire dragon just after I was reincarnated into this world.
The dragon king was also a bit troublesome back then that I even had to store him inside the system inventory.
The next powerful opponent that I had faced was some supreme demons which were totally out of my league if I had not acquired skills that could improve my stats such as [Mana Stack] and [Berserk].
The archdemons followed after the supreme demons which I had thought wasn't just a simple coincidence.
The archdemons were too powerful but I was able to defeat them with the help of my teammates.
What's suspicious about the attack of the archdemons was the fact that Axel 2 had speculated that Damien Miles was the one who instigated the attack.
Now that I had thought about it, did all of the human heroes including Damien Miles died at the hands of the demons?
I only received intel from the people at the Holy Church that the human heroes including Damien Miles died because of the demons who attacked their carriage which was heading towards the Holy Church.
Maybe the human heroes didn't die but instead had been abducted by the demons or something worse could have happened.
{That should be possible, Axel 1. As expected of my main counterpart! You were able to speculate this much with such little evidence.}
It seemed that Axel 2 was observing my situation for a while considering he replied to me just after I speculated about Damien Miles and the human heroes.
I should dig deeper about that case since it might lead to some potential clues that would help me solve the root of the problem.
I might also know the reason why Damien Miles or the 'should be a clone of Damien Miles' attacked me with the other archdemons.
Furthermore, I might also know the reason why the Gods had immense hatred against the demons to the point that they would send other beings from planets such as Earth to eliminate the demon lords.
I wouldn't even be surprised if the Gods would eliminate the demon lords themselves.
If the heroes weren't able to defeat the demon lords, then it might be possible for my speculation to be right on the spot.
The Gods might just act against the demon race personally if the heroes managed to fail in defeating the demon lords.
Furthermore, I don't know the reason why the Gods were hostile against the demon race but not towards the entire monster race including the goblins.
I would have preferably believed that the Gods were hostile against the entire monster race instead of the demon race only which should have been much more of a plausible assumption.
The monster race had brought disaster against the human race which was the so-called 'direct descendants of the Gods.
Well, not that I'm against the belief of the humans since I was a human myself in my past life, not that I'm rooting for the humans or anything like that.
I'm getting sidetracked so I must focus on the main objective at hand.
The last powerful opponent that I had faced was the fire lion emperor but since I was a hero that could defeat anyone above my level, it wasn't that much of a surprise for me.
It was much more natural for me to defeat anyone above my level since I had much more intelligence and wisdom stat than the average being in this world and not to mention my large mana pool.
I also had a deep understanding of the elements which I had learned from the periodic table and the theories behind the formation of the elements which was the reason why my magic was much more powerful than the average.
I had read from a book that mentioned that magic spells were boosted in terms of potency and efficacy if the visualization of the magic spell was enacted during the casting process.
It must also be one of the reasons why the Gods had summoned the humans from Earth because humans from Earth knew about the elements surrounding them due to science.
If I keep this up, I might be able to defeat the demon lord in a month with this rate of progress and as long as I don't hit a bottleneck in my improvement in my sword techniques.
{How laughable! Even though I don't want to offend and ridicule Master Axel, I couldn't help but laugh at the master's wishful thinking.}
The dragon quickly retorted by speaking to me via telepathy.
Enlighten me then, Dragon King.
{Very well. If Master Axel wants me to tell the reason why I'm acting like this then I might as well enlighten Master Axel.}
{The demon lords are much more powerful than Master Axel had thought. The ancestor of the demons had defeated me singlehandedly a thousand years ago.}
Wait, I thought you were at your peak condition a thousand years ago?
{I was but even if I was at my peak condition, I wasn't even able to defeat the ancestor of the demons.}
Well, I'm not that troubled since the demons that you were talking about were the ancestors of the current demon lords, not the demon lords themselves.
{I do admit that the current demon lords were much weaker than the previous several generations but even if their power degraded, they were still a force to be reckoned with.}
Oh, I had not thought about that. I should keep this in mind to not provoke the demon lords at the early stages.
I'll chat with you later, Dragon King. I needed to head to my teammates first and give them a heads up about the situation.
{Ok. Take care, Master Axel.}
You too.
After my conversation with the Dragon King ended, I headed towards the protective array to meet up with my teammates.
