First, the open-world gameplay was already outstanding; everyone was in the same world, conducting transactions and trade with extremely high freedom, and they could even choose which Dungeon to enter.
Leaving aside the trading system, just the self-selection of Dungeons was already very unique, exceeding everyone's expectations.
Although each Dungeon had a level distinction, at least the choice was their own, without the feeling of being forcibly assigned.
Moreover, weaker Adventurers could also choose to clear earlier Dungeons and tackle later ones once they leveled up.
Furthermore, the blend of technology and magic also gave countless Adventurers a novel experience.
Or rather...
Every class here was novel.
The Ghost Swordsman, possessing the power of the Ghost Hand.
The Gunner, wielding technology.
A level 5 Female Mage could even learn Summoning, summoning an enslaved Goblin Warrior, which was also a very astonishing setting.
Because Summoning was too rare in other Dungeons.
The reason for this was that the monsters placed in Dungeons were all hostile and would not easily obey the Adventurers' commands.
This problem also became a major headache for countless Dungeon Lords.
Otherwise, there would be no need for NPCs; simply fabricating one would suffice.
To solve the problem of too many Adventurers and NPCs being unable to face numerous Adventurers simultaneously, Dungeon Lords even developed the Myriad Clones.
By using replication mirror magic, they created one NPC clone after another and placed them in individual worlds.
Lord Chen used this method to replicate countless Ansaelia and place them in the treehouses.
Therefore, what those Adventurers encountered were all just clones; these clones would shatter upon touch, and their memories were pre-set.
The real Ansaelia never existed in any Adventurer's treehouse; she had always been at the top of the Dungeon world, managing the entire Dungeon.
Other NPCs did not use the Myriad Clones setting, unless the streets became too crowded in the future.
This replication magic of Myriad Clones, of course, had both advantages and disadvantages.
The advantage was that it could alleviate the pressure on NPCs.
The disadvantage, as mentioned earlier, was that it shattered upon touch, which made it unusable for Summoning.
Finally, to solve the problem of summoned creatures, many Dungeon Lords chose Charm Magic, using Charm Magic to help Adventurers control their summoned creatures.
But the problem was...
Charm Magic was considered a top-tier magic, requiring very high basic logic from Dungeon Lords.
Most people really couldn't create it.
Only a small number of Dungeon Lords could construct a Dungeon with Summoning.
And only a small fraction of that small number could construct a Dungeon with a large amount of Summoning; the more summoned creatures, the greater the difficulty of construction, and the difficulty increased exponentially.
But with Chen Yu.
Through the promotional video for the Female Mage's advanced class, Summoner, it could be seen that the types of creatures a Summoner could summon were incredibly numerous.
What Goblin Warrior, Minotaur King, Elf King, Archmage Sister, Light, Dark, Water, Fire Arch-elementals and Lesser Elementals, and even the invincible Apostles could be summoned.
In the eyes of other Dungeon Lords, this was simply outrageous...
How much Charm Magic would be needed to summon so many creatures?
One person would have dozens of summoned creatures, and hundreds of people would mean thousands or even tens of thousands.
Would this really not go wrong?
It really wouldn't!
Because Chen Yu, in dealing with this tricky problem, simply added a collar and solved it.
The Adventurers couldn't understand what kind of magic a collar possessed to control these summoned creatures.
This technology, which they called from 'Heavenly Realm,' also became an unsolvable problem for other Dungeon Lords.
Because they would never understand the underlying logic of technology.
This was also why Chen Yu was not afraid of Resident Evil being imitated by other Dungeon Lords.
No matter how much you imitate it.
It would only be a resemblance; you would never understand the operation of firearms or the generation of electricity.
Unless he could be like Chen Yu, possessing the common knowledge of billions of people from another world.
Based on such a unique advantage.
Chen Yu's Dungeon, this vast Dungeon and Eight Million Warriors system, even at its initial glimpse, could make countless Adventurers flock to it.
Whether it was the mysterious power of the Ghost God or the destructive 'Heavenly Realm' technology.
Or the incredibly complex summoning system, all were enough to make Adventurers yearn for them.
Longing for the day.
They could possess all the skills and become the warriors who saved this continent.
"Actually, the main thing is that it's too difficult; damage is like scratching an itch, fighting small monsters is like fighting a Boss, I always feel like something is wrong!"
Someone complained in the world chat channel.
Lord Chen's Dungeon focused on high difficulty and fun, making them love and hate it, enjoying happiness in suffering and experiencing suffering in happiness.
Some complained, of course, and some pointed out the problem.
"You don't have any equipment on you, of course, something's wrong; you need to go get equipment! Didn't you see so many people exchanging equipment at the Blacksmith Uncle's place?"
A word of awakening.
Several Adventurers then realized that the equipment they dropped from monsters could not only be exchanged with teammates.
But also with others.
At the entrance of the blacksmith shop on the outskirts of the forest, Adventurers waiting to trade had already gathered.
"Level 5 gauntlets for a level 5 katana, private message if you have it."
"Level 5 cloth armor belt for same-level plate armor, no head or shoulders."
"Who has an automatic pistol? I'll buy it with gold coins, or I'll pay 100 happy coins."
"Level 5 blue magic staff, level 5 green ring, private message if you want it, scammers stay away."
"I have a purple axe here, who wants it? Name your price!"
"..."
Upon entering this area, a marketplace-like atmosphere immediately greeted them.
At this stage, most people only had white or green equipment.
Blue was considered top-tier.
Exchanges were usually of these qualities.
But once a purple weapon appeared, it was a big deal, and a crowd would rush to get it.
After all, resurrection coins were too expensive.
To level up steadily to level 10, a full set of level 5 equipment was essential.
