Upgrade five levels in a row and leave the underground palace!
Ninth Level of the Underground Palace.
Lin Xuan killed the World BOSS with a single palm strike and casually picked up the dungeon core on the ground.
"I've finally acquired all the dungeon cores from every level."
Lin Xuan let out a long sigh of relief.
He hadn't stopped at all during this time.
After entering the Fourth Level of the Dungeon and eliminating the five thousand Demon Race members who had entered from the Ninth Level of the Dungeon earlier, Lin Xuan continued to kill his way downwards.
His goal was to completely control this dungeon.
Now, the ownership of these lower levels was finally back in his hands.
During this period, the reserves in the blood gourd were almost depleted.
It was currently hanging at his waist, absorbing air to automatically replenish the potions inside.
"Let me see what benefits come from controlling an entire dungeon."
Lin Xuan smiled faintly, feeling a significant reduction in the pressure on his mind.
He had been under constant pressure ever since he learned about the standoff between the two armies outside.
After all, he was in a special position.
If he didn't do something, he wouldn't be much of a person.
"You have acquired nine dungeon cores from different levels!"
"Detection: You have cleared a complete dungeon!"
"Congratulations! Level +5, Free Attribute Points +100, Ancient Artifact of your choice x1, Random Mythical Magic Card x1."
"The complete dungeon authority key has been synthesized!"
"Complete Dungeon Authority Key": The core of the entire dungeon, only one will be synthesized, possessing complete dungeon authority!
"Holy crap!"
"The rewards are so generous!"
The five-level increase and free attribute points were not worth mentioning.
After all, during this time, after clearing the dungeon and killing tens of thousands of Demon Race members, even with the experience penalty mechanism due to the significant level difference, Lin Xuan's level had already risen to seventy-two.
If he were to kill monsters in the wilderness outside, it would take at least half a month.
"Seventy-seven, the same level as Zhang Fan."
Lin Xuan was in a good mood.
Zhang Fan, who attended a military academy, had early exposure to dungeons, and when they met, Zhang Fan's level was exactly seventy-seven.
At that time, Lin Xuan's level had just reached sixty.
He didn't expect to catch up to him in just three or four days.
Of course, the rapid level increase these past few days was a minor matter.
His attributes, equipment, and skills had all seen significant improvements.
Thinking of this, Lin Xuan once again thanked Chen Wanqiu.
Without her, he might still be grinding dungeons at Mingzhu University.
He hadn't intended to get involved in this mess initially.
"It's time to go out."
Lin Xuan didn't rush to choose the most luxurious rewards: the Ancient Artifact of his choice and the Mythical Magic Card.
Half an hour ago, he had already discovered that the ox horn could no longer contact Chen Wanqiu.
It was very likely that a battle had already begun outside.
It was time to leave the dungeon and proceed with the next plan.
Whoosh—
Lin Xuan mounted the purple golden gourd, collected all the items dropped by the monsters killed by the Skeleton Soldierss in the Ninth Level of the Dungeon, as well as all the Skeleton Soldierss, into his Frost Domain.
Then, holding the dungeon key, he directly teleported from the Ninth Level of the Dungeon to the First Level of the Dungeon.
With the complete dungeon authority key, the additional permissions included changing the entry and exit rules of any level's dungeon teleportation gate, and the ability to use the key to teleport to any level's space.
Of course, there was also a very powerful permission: a professional with the complete authority key could fine-tune the spatial structure of each level within seventy-two hours of possessing the key.
The first two merely facilitated the person with the authority key.
But the last one was crucial.
A dungeon's protection for the authority holder was seventy-two hours; even with the complete dungeon key, after seventy-two hours, the dungeon's rules would reset.
This meant that the entrances to the First Level of the Dungeon and the Ninth Level of the Dungeon would reopen.
This was a rule beneficial to the attacking side.
But with the complete key, it was different.
He could completely change the dungeon environment, gaining a significant advantage in geography and vision!
Crack crack—
Lin Xuan stabilized himself on the First Level of the Dungeon, simultaneously casting Summon Undead and stacking his maximum HP.
"Still can't reach her."
Lin Xuan looked at the ox horn in his hand, frowning.
Logically speaking, as the youngest daughter of the Chen family, one of the four major families in Jianghai City, Chen Wanqiu's status, if not noble, was certainly not something ordinary people could compare to.
Yet, she insisted on being at the forefront of everything.
When valuable items from the Chamber of Commerce were left behind at the Divine Grace Cemetery's old camp, she was responsible for recruiting people to handle them.
Would the Chen family still let her get involved in such a large-scale military battle?
If he remembered correctly, Chen Wanqiu's level was only around eighty, right?
Unable to figure it out, Lin Xuan simply put down the ox horn and focused on summoning Skeleton Soldierss and consolidating his forces.
As early as after killing nearly ten thousand Demon Race soldiers, he had already made several plans.
First and foremost was to consolidate his forces and upgrade his skills.
As the saying goes, sharpening the axe doesn't delay the chopping.
To maximize his effectiveness in a battle involving hundreds of thousands of troops, Lin Xuan needed to elevate his own strength even further.
Regarding his forces, Lin Xuan had just done a quick count.
Currently, within his Frost Domain, Skeleton Soldierss were the most numerous, with nearly two hundred seventy thousand troops.
Next were Skeleton Archers, with sixty thousand.
Skeleton Knights and Skeleton Cavalry totaled fifty thousand.
As for Skeleton Mages and Skeleton Priests, they were relatively few, less than twenty thousand combined.
These Skeleton Soldierss, all told, amounted to four hundred thousand.
Four hundred thousand Skeleton Soldierss.
If they were to face two hundred thousand ordinary people, they would certainly have a chance of victory.
But on the ground were two hundred thousand regular troops from the Moro Realm.
Four hundred thousand regular troops from Blue Star would be needed to contend with these Demon Army.
However, Lin Xuan didn't only have Skeleton Soldierss.
Besides those he summoned, he could also, after transforming into the Lich King, convert the monsters he killed into undead creatures and strengthen them.
This was his trump card for dealing with the Demon Army!
The monsters within the dungeon were at least level one hundred, and almost all of them were elite monsters.
After being strengthened through undead conversion, they could be said to be more powerful than some soldiers.
Of course, this was only in terms of individual strength.
The combat power of a regular army was not just about strong individual strength, but also coordination.
Furthermore, in large-scale battles, morale could also provide a combat boost.
Morale here was not just a simple saying; it was a tangible, special BUFF.
Once soldiers' morale soared during battle, they could, by relying on characteristic military formations, naturally form super-large army BUFFs.
The power of these BUFFs varied.
It was said that the strongest could enable three thousand troops to annihilate one hundred thousand of the enemy!
"One hundred twenty-nine thousand five hundred undead creatures."
Lin Xuan finished counting the monsters from the Ninth Level of the Dungeon that had just been converted into undead.
Currently, all the undead creatures within his Frost Domain combined amounted to approximately five hundred thirty thousand.
"If I summon them all at once behind the Demon Race army after I go out, it should be enough!"
"At worst, I'll give them a massive five hundred thousand-strong fireworks show!"
After collecting the newly summoned Skeleton Soldierss into his Frost Domain, Lin Xuan gripped frostmourne tightly and took a deep breath.
"Teleport!"
