Rebirth of the Strongest Dungeon Master

A wild, bright orange and yellowish flame burnt in the centre of the sky. At the top of the rock cliff, Isaac sat watching the sun gradually melting into the water. Right below him, hundreds of monster carcasses were piled high.

[The 30th challenge is complete.]

[You get 1,000 zenny and a weapon artefact 'Vampiric Dagger (D)'.]

[Upgrade the dungeon to the 4th floor to gain access to the next 10 challenges.]

[Congratulations! You are the first demon to successfully conquer 30 Challenges.]

[Title 'First Challenger' has been obtained!]

[Passive effect: every physical damage taken is reduced by 10%.]

[Constitution increased by 5.]

After 6 months of hard work, the Challenge Dimension was finally over. During this time, Isaac had earned a lot of experience and rewards. He even got a new title. However, there was no expression of joy on his face.

Isaac opened his status window.

<Status Character>

[ Isaac Constantine - Lv 75]

[ Rank : 99th - Baron ]

[ Title : Chief of Beast, First Challenger]

[ Skill : 1/3 ]

[ Strength : 50 ]

[ Magic : 140 ]

[ Constitution : 61 (66) ]

[ Dexterity : 83 ]

[ Perception : 80 ]

[ Unallocated stat points : 20 ]

Although Isaac's individual level was on par with Dukes, in the next 12 months, he would be overtaken by other demons.

For now, not many demons were thinking about completing the Dimension Challenge. Because they thought of upgrading the dungeon first, then cleared the entire Challenge at once. That way, they could leave the dungeon strong.

Isaac's journey to winning this game was still long and tough. He needed to work even harder.

After that, he took out a black stone from his inventory and stroked it. A portal appeared, then he stepped into it.

Isaac returned to where he last stayed, the Crystal Core room. The first thing he did after stepping on the floor was to unlock his Dungeon status.

<Dungeon Status>

[Dungeon Floors : 3/3]

[Monster Boss : 0/3]

[Population : 77,987/300,000]

[Fund : 156,800 zenny]

His eyes narrowed when he saw the current population of the dungeon.

"I remember filling the population completely. Now there is only a quarter left? The humans must have enjoyed slaughtering my monsters."

This number was relatively small, but this was normal for the first 6 months. Considering his dungeon had no boss and only weak monsters roaming around here. So the dungeon became a popular place among humans because it was easy to conquer.

After the first year of catastrophe, the Hunter profession increased drastically. Isaac was confident his income would be at least around 100,000 to 300,000 zenny per month when the transition period was over.

For now, Isaac put that matter aside.

"I've gathered enough materials from the Dimension Challenge rewards. Time to upgrade the 'Seeds of Mind'."

Isaac accessed the 'Shop' then selected the 'Upgrade' option.

[Upgrade skill 'Seeds of Mind (D)' ?]

[Material : 0 ]

[Percentage of success : 0.00%]

Monsters, items, artefacts, skills, and monster bosses; everything sold in the Shop could be upgraded to increase its class. On the condition that they had to sacrifice the same type of material.

Since Isaac was going to upgrade 'Skill', he had to sacrifice 'Skill'.

"I got a lot of useless skills from completing 30 challenges."

In Isaac's inventory right now, there were 20 skill scrolls. All of them were low class E, and most of them were of no use at all.

Isaac put skill scrolls as materials.

[Materials : 4 ]

[Percentage of success : 50%]

The higher the class was sacrificed, the fewer materials were used. However, if we used low grade materials, more materials needed to be sacrificed. Each percentage given was different, depending on the class of material we want to upgrade.

Actually, as long as the chance of success was 50%, Isaac could just process it straight away. Hence, since Isaac didn't enjoy relying on luck, he sacrificed another 4 skill scrolls.

[Material : 8 ]

[Upgrade percentage : 100%]

[Upgrade? Yes/No]

Without hesitation, Isaac chose the 'Yes' option.

Ding!

[Upgrade successful!]

[Skill effect added]

A new notification screen appeared. The information description for 'Seeds of Mind' had just been updated.

<Seed of Mind>

[Class : C]

[Type : Skill]

[Users can control the mind of all kinds of living beings (except demons).]

[Exp or zenny bonus (20% of the original amount earned) will be given to the user if every living thing that is implanted by a seed kills a monster or a human.]

[Limit of seeds that can be planted : 4]

A subtle smile curved on Isaac's lips. This was the secret of this skill, controlling humans!

Isaac had no plans to use this skill on monsters, but he would use it on humans.

He would plant 'Seeds of Mind' on Hunters, then send them to the enemy's Dungeon.

Of course, he wouldn't carelessly choose a Hunter. He had to choose the best of the best.

No demon would have thought that the humans they used to view as livestock were actually soldiers of a demon.

This was Isaac's plan, but this was only part of it.

Ding! Ding! Ding!

Just as Isaac was deep in thought about his plan, there were repeated beeps of notification. Instantly, a transparent blue screen appeared in front of his face.

Messages that had been pending during Isaac's absence from the Dungeon had just entered the system.

Without thinking, he immediately opened it. His eyes opened wide when he saw the contents. After that, he chuckled amusedly.

"Look at you guys, so spirited ."

[Pending message received]

[There are 72 PvP requests.]
