There are two ways to activate the Green Moon Altar. One is to use the blood of 'natives' for a blood sacrifice, which is fast, but the drawback is that it requires a lot of killing.
The other method is simpler but takes a bit longer.
During Naruto's absence, he kept the Green Moon Altar on the Ghost Ship, allowing the Ghost Ship to travel the world while the Green Moon Altar absorbed the Red Moon essence and Green Moon essence of the Goblin Slayer World every night.
Now, the Green Moon Altar has absorbed enough moonlight to open a teleportation passage to a much larger and more distant Red Moon.
Without hesitation, Naruto gave the Ghost Ship the command to sail randomly, then stepped onto the altar, and his figure was immediately engulfed by a pillar of light.
"Whoosh"
A surging stream of light particles enveloped Naruto, distorting space and instantly rushing into the sky, arriving on the distant Red Moon.
When the stream of light reached the Red Moon's surface, Naruto landed steadily, feeling a strong sense of dizziness and nausea.
However, with his physique, these negative effects from super long distances had little impact.
"Is this the surface of the Red Moon?"
Naruto immediately looked around.
What greeted his eyes was a scene like a lava purgatory: high temperatures, barren land, and the air emitting a strong, pungent sulfur smell.
And the larger Red Moon had even gathered an atmosphere, so there was air on the surface!
It's just that due to the Red Moon's surface ecology and environment, the air here has a different composition than the air on the Goblin Slayer World's continent.
A larger proportion consists of toxic gases.
Humans can breathe it, but not for too long, otherwise they won't die from lack of oxygen but from poisoning.
Naruto's expression was normal.
As a perfect life form, even not breathing was fine. As long as he used the Blood Demon Art, which can absorb natural energy, to continuously draw energy to sustain his cell activity, Naruto could completely do without breathing.
[Scarlet Moon]
[Source World: Goblin Slayer]
[Recommended Level: 50 ~ 200]
[Description: This is the Red Moon, one of the Goblin Slayer World's twin moons. Unlike the Green Moon, which was rendered green by the Goblin race's origin card,
this place is stained red by blood and magma. It is the Underworld recorded in the history books of human nations, inhabited by a large number of monsters, and even Demon Gods, and even the legendary Demon God King is slumbering behind the scenes!]
"Scarlet Moon? Underworld? Demon God?"
"The recommended level is at least 50, and can even reach 200. It seems like a large dungeon."
'I estimate it can also be divided into many smaller dungeons.'
Naruto glanced at the pop-up window that appeared in his vision and took a slight deep breath.
He hadn't expected that the Red Moon would be the Goblin Slayer World's strongest Underworld dungeon.
Not to mention monsters much stronger than those on the Goblin Slayer World's mainland, there are even the Sixteen Demon Generals of the Underworld, and the Demon God King.
"Awoo!"
A spine-chilling wolf howl echoed.
A foul wind swept over. From a scarlet cliff not far away, a giant maned wolf, ten times larger than a bull, suddenly pounced towards Naruto, opening its gaping maw, saliva dripping, and biting at Naruto.
This wolf's mouth, filled with sharp fangs, could swallow the entire Naruto in one bite.
But Naruto, seemingly oblivious and lost in thought, stood still, unmoving. Only the shadow behind him suddenly grew larger, and with a "whoosh," dozens to hundreds of sharp thorns shot out, instantly piercing the giant maned wolf that had leaped into the air.
[Eliminated a Giant Demon Wolf, Experience + 300 points]
"Only 300 experience points? That means I need to kill a hundred Giant Demon Wolves to get 30,000 experience points."
Naruto raised an eyebrow.
30,000 experience points wasn't even enough for him to level up once.
"Roar!"
After killing the Giant Demon Wolf, wolf howls echoed one after another all around.
Giant Demon Wolves, one after another, emerged from behind the surrounding lava hills, their cold, green eyes fixed on Naruto, eyeing him menacingly.
Naruto threw an Appraisal Eye, and found that these Demon Wolves, some were Hell Wolves, some were Giant Demon Wolves, their species were not the same,
but they seemed to have a common leader - the Hellhound!
It was also the BOSS of the current small dungeon.
Level unknown.
But definitely not weaker than Dragon Mother Tiamat!!
"Interesting, this Red Moon place is a good leveling spot."
Naruto's lips curved into an interested smile.
There were simply too few high-level monsters in the Goblin Slayer World.
In the Underworld, even a random small BOSS on the Red Moon could seemingly slaughter the human nations.
But for Naruto, this place became a treasure trove for leveling up.
If he cleared the Underworld, would he still worry about not raising his level?
"Awaken!"
"Become my Shadow!!"
Naruto put on the black crown, transforming into the Shadow Monarch, and spoke to the Giant Demon Wolf impaled by the shadow thorns and hanging in mid-air.
Instantly.
The thorns that had pierced the Giant Demon Wolf's body seemed to melt, turning back into a pool of black ink, which then continuously flowed into the Giant Demon Wolf's body.
In a short while.
The absolutely dominated Giant Demon Wolf revived, roared at Naruto, and lowered its proud wolf head, showing submission.
The Hellhound was clearly still alive, but Naruto was now the true master of the Giant Demon Wolf.
"It's just like a necromancer..."
"No!"
"Even more abnormal than a necromancer!!"
Naruto beckoned, and the Giant Demon Wolf immediately came over, actively tilting its head and affectionately rubbing against Naruto.
"The main body does not die, the Shadow does not perish."
"Unless I actively Release the contract, or die, otherwise you will be truly immortal and imperishable." Naruto said indifferently, as if speaking to himself, and also as if chatting with the Giant Demon Wolf.
The problem was, how difficult was it to kill Naruto's main body? Even he didn't know.
Indirectly, this meant that the Giant Demon Wolf transformed into a Shadow would also not die.
Furthermore, as the Shadow Monarch's authority, the experience points from monsters killed by this Giant Demon Wolf would be credited to Naruto, similar to the effect of a Shadow Clone.
Shadow Clones have a limit due to the limit of the Multiple Shadow Clone Jutsu.
But Shadows do not!
The stronger the existence Naruto kills, the stronger the Shadow it transforms into.
A typical example is the Black Dragon Monarch.
Just this point alone is something a necromancer cannot compare to.
"Since killing them gives me experience, and I can summon them to become Shadows."
"Why don't I create a magnificent and invincible Shadow Army?"
Naruto's heart burned with excitement. Thinking of it, he immediately acted, directly performing the Multiple Shadow Clone Jutsu, and began to eliminate the surrounding menacing Demon Wolf pack, then continuously used the Shadow Monarch's absolute dominion authority to turn them into his "Shadows."
Unbeknownst to him.
Naruto was followed by hundreds of Demon Wolves, besieging the lone Hellhound.
Naruto didn't even need to personally intervene. Nearly a thousand Demon Wolves, plus the Black Dragon Monarch, directly blew up the originally powerful Hellhound!
With a loud "bang."
The Hellhound, like a small mountain, fell into the lava lake.
