The undead herd has been destroyed.
　All we have to do now is to settle it with Mobius.

　However, it's quite a long way to the cave in the north.
　I activated the Necro-Earth and called out the Black Dragon of Extreme Extinction.

''Gau.''

　The black dragon spun its long neck around and turned to me.

''Gauuuuuu.''
...... "Are you trying to say, 'Keep your guard up, keep your head up'?

　It was a complete guess.
　But apparently it was the right answer, and the black dragon nodded deeply.

''Gawgaw.''

　The black dragon seems somewhat happy.
　He seems to be in a good mood and bends over to urge me to get on his back.

　The black dragon's back is bumpy, and there are many areas of wispy scales that can be used as seats.
　As we sat down in a good spot, the black dragon slowly moved its wings.

　It seems that some mysterious power is working on the black dragon's back, and we were able to sit down comfortably without feeling any shaking.
　Except for the lumpy scales, it's no different than a modern airplane.

　...... Not long after the black dragon began to fly, a voice was heard in my head.

''Level is now 64.''

　Having burned down the undead horde, I was already level 64.
　The golems are currently sweeping up the remaining enemies, but their experience must have entered me and raised my level.

''The conditions for obtaining the sub-skills within the 【Otherworlder】 skill have been met. [Tactics Support] will be released.''

　Apparently, I've acquired a new skill.
　What could be the effect?

　...... I see.

　To briefly summarize, [Tactics Support] seems to be "a skill that assists in leading ancient weapons in battle".
　The image is similar to recent strategy simulation games with real time elements, such as "Romance of the Three Kingdoms" or "Nobunaga: Ambition".

When I activated 【Tactics Support】, the location information of the golems was displayed on the map in my brain of 【Auto Mapping】.
　It seems that if you focus on an individual golem, you can share your view.
　Furthermore, it also has a telepathic-like function, and it seems to be able to give orders just by remembering!

　When I tried to use it, a window opened in my head that looked like a chat.


　＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿

　Ko: Can you all hear me?

　Guardian Golem A: Ack, Master contacted me!

　Guardian Golem B: Awesome, I can talk to the master!

　Guardian Golem C: Defeat the undead!

　Destroy Golem A: I killed it too!　I want a homage!

　Ko: Good job. Each of you, continue the battle as is.

　Guardian Golem A-L: Yes, sir!
　Destroy Golem A-D: Wakatazo!

　＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿


　Apparently, they can also receive reports from the other side.
　This is convenient.

　The destruction of the undead will be over soon, but after that, I'll have the golems keep an eye on the area, just to be sure.
　The black dragon also advised me to brace myself, and you never know what's going to happen in the world.

　Just when I thought I had defeated Mobius, I was attacked by an unexpected ambush soldier, I was in big trouble for being careless!
　I'm definitely not going to let that kind of development happen.



　* *.



　Eventually we reached the cave to the north.
　We got there, and it was ...... strange.

　Iris muttered, stunned.

'The cave is gone ......?'

　Yes.
　The northern cave or something like that had disappeared, and in its place, a huge crater had been created.
　It was like a scene after a meteorite had fallen.

　...... Lily turned to me and muttered.

''Ko-san ...... 'I traced Mobius's magic back to him and burst his attack magic, right, ......?''
Yeah, you're right.

　I nodded.

'I shot a dark burst into Mobius' body.
Maybe that's why, isn't it ......?

　I activated the Dark Burst with absolutely no effort at all.
　As a result, I may have blown up the entire cave and Mobius.

　Next to me, Iris shouted in surprise.

''Dark Burst is the lowest level of attack magic, isn't it ......?　It's too different from the Dark Burst I know: ......
The power of a sorcerer's magic depends on his abilities. That's what I learned at the Academy of Magic: ......
'I'm really glad Ko isn't the enemy. His swords and magic are top-notch, and he's way out of his human league. ......

　Iris sighed in admiration and continued with more words.

'I wasn't sure if I should go into it or not, but this dragon is the black dragon of Onen: ....... It's amazing that you're resurrecting a black dragon as a matter of course, and as a dragon person, I'm too afraid to ask you to ride on the dragon's back and my heart is about to explode, but for now, we have to kill Mobius first, so we can talk about the details later, thanks for listening.

　Oh, whoa?
　I don't know what it is, but it seems that Iris has cleared her mind in her own way.

''I mean, I wonder if Mobius is still alive ....... With this explosion, no matter how much of an ancient great sage he is .......''
No, he's alive.

　I've been activating the [Enemy Radar] since a while ago, but there was a reaction just around the hypocenter.
　I ordered the black dragon and approached the hypocenter while reducing the altitude.

　There, a skeleton in tattered clothes was lying on the ground.
　Its bones were charred in places and it was giving off white steam.

　This is, perhaps, Mobius.
　I'll use [Appraisal] to confirm it.



'Mobius Megistris (Race: No Life King).

　Description: an ancient sorcerer who became the highest-ranking undead due to a forbidden curse.
　　　　Over the course of five thousand years, he has eaten numerous souls and obtained a powerful power.
　　　　With tens of thousands of undead in tow, he is just like the demon king of the mythical age.
　　　　Due to the lack of sacrifice, his body is made up of only bones, but his physical and magical defenses are high.
　　　　Even if it destroys its body, it is capable of living on its soul alone semi-permanently.''


　
　Apparently, it's definitely Mobius.
　Just from the description, it looks like it's very strong.

　It's tricky to be ...... able to live on a semi-permanent basis with just a soul, but I'm already thinking about countermeasures.
　I'm thinking about it, or rather, a certain skill taught me.

[Book Information Processing].
　Do you remember what I did after I retrieved the books from Mobius' lab?
I did a search on "What is the Great Sage Mobius trying to do?" and got a lot of information.
　It included how to deal with Mobius.

　In order to completely annihilate Möbius, he would have to meet the following three conditions.

　1. destroy the body and return it to a state of soul only.
　2. inflict great mental damage and shake the soul.
　3. purify it with a weapon that has obtained the "Light that Shines in the Darkness" ...... moon's blessing.

　The last condition seems to be a bit more difficult, but I had actually already completed it.
　Hero-Slayer's Great Sword.
　All that stands out is the skill blocking, but there are other granting effects as well.

　-- "Moon Blessing S+".

　Fortunately, tonight is a full moon.
　Even I can't predict how powerful it will be.
