612 Rank Up (Part 1)

Three days after Evan returned to Astarte City...

"So you will be staying there until the things settle down?" Sebastian asked, looking at Nathan's hologram.

"What else can I do?" Nathan said while rubbing his eyebrows, "Aside from Ron, there are very few high-level hunters left in Naphliam City. I can't leave right now even if I want to."

Sebastian nodded his head hearing Nathan. He also knew that most of the hunters of Naphliam City were wiped out by Evan's shadow undeads.

"What do you think about the situation of Central City?" He asked after a few seconds.

"I don't know what those guys are planning now," Nathan said with furrowed eyebrows. "They did not attack Central City but two days ago many monsters started to gather in the wilderness of the Central City. According to the last report that I received a few hours ago, the number of monsters who gathered in the wilderness of Central City already exceeded three million and their number is still increasing."

"If such a large monster army attacks Central City, I am afraid its fate will be no different from Ravenhurst City," Sebastian said in a concerned voice and sighed loudly.

"There is no point thinking about all these things. Let's wait and see what those monsters are planning because if they wanted to attack Central City they would have done it long ago." Nathan said and looked at Sebastian. "By the way, what is that guy doing?"

Sebastian shook his head hearing Nathan.

"I don't know what he is planning. He came back three days ago and told me he wanted to enter an S rank dungeon." Sebastian said and smiled warily. "But all the S rank dungeons in Astrate City were on cooldown so he went to an A rank dungeon."

"He went inside a dungeon?" Nathan raised an eyebrow at Sebastian's words. "Does he want to raise his core rank to S."

"I think so too but…" Sebastian said and showed a confused expression. "As far as I know he advanced to A+ rank about two months ago. Can he really increase his rank again so soon?"

"Now that you mention it.." Nathan also showed a confused expression when he heard Sebastian. "It should be impossible for his core to stabilize in just two months after advancing to A+ rank."

Sebastian scratched his head hearing Nathan and said in an uncertain voice. "Well...if you think about it carefully it doesn't sound impossible."

"What do you mean?"

"Did you forget? Around six months ago that guy was just an F rank hunter and now he is already at A+ rank." Sebastian said and showed a helpless smile. "Do you still think it is strange for him to increase his rank again?"

Nathan's mouth couldn't help but twitch hearing Sebastian.

'Just what kind of hack he is using to increase his rank so fast?' He thought inwardly and shook his head.

"Did he tell you anything before entering the dungeon?"

Sebastian shook his head hearing Nathan because Evan did not tell him anything.

"Is that so," Nathan said and looked at Sebastian, "Let me know if something happens."

"Sure," Sebastian said and ended the call. After ending the call he stood up from his chair and looked out his office window towards the dungeon that Evan was in.

"He didn't bring his summoned monsters inside the dungeon, so it may take him around ten days to clear the dungeon," He muttered in a low voice.

As Sebastian was looking in the direction of the dungeon, he suddenly realized something and narrowed his eyes.

"Why is the Mana rushing in that direction?" He said to himself, looking in the direction of the dungeon Evan was in.

Thinking something was not right, he left his office and flew in the direction of the dungeon Evan was in.

While flying in the direction of the dungeon, Sebastian saw a giant mana vortex that was nearly thirty kilometres in diameter forming above the dungeon.

"What the hell is that thing?" He said with his eyes wide open and stopped a few kilometres away from the dungeon. He looked towards the centre of the mana vortex and noticed an unfathomable amount of mana moving inside it.

Bang!

Suddenly, a booming sound echoed throughout Astarte City and a vast amount of mana came out from the vortex like tidal waves and went towards the entrance of the dungeon.

Sebastian gulped down his saliva at the sight of such a large amount of mana and looked in the direction of the entrance of the dungeon.

When he looked towards the entrance of the dungeon, he noticed someone standing there but because of mana waves, he couldn't see the face of the person who was standing there.

Although he wasn't able to see the face of the person, Sebastian easily recognised him.

"The mana vortex that formed when I reached S Rank was just five kilometres big but this vortex.." He muttered in a low voice and came to the ground from the sky.

Soon he began to sense a powerful aura that was far stronger than any aura he had felt till now coming from the direction of the dungeon.

Around half an hour later, the mana vortex that was spinning above the dungeon started to disappear.

The aura that Sebastian felt earlier also became far more powerful and just by looking in the direction of the dungeon, he could feel his soul shaking in fear.

Soon the mana vortex that was in the sky completely disappeared and everything returned to normal.

"He successfully reached S Rank."

Sebastian said to himself and was about to move towards the dungeon when he felt something and his face turned pale.

Bang! Bang! Bang! - - - - -

Some small explosions resounded in the area Sebastian was in and soon auras of hundreds of S rank monsters erupted from the direction of the dungeon.

"Wh-what the hell is going on?" Sebastian asked in a shocked voice when he felt the auras of so many S rank monsters.

He was still in a shocked state when he once again felt something and looked in the direction of the dungeon where Gobu and Evan's other shadow undeads were staying and felt more auras of the S rank monsters.
