The fourth floor of the Demon King's Castle.

After Lu Ming and the Holy Maiden walked up, they found that this was a tomb that had been buried everywhere, and the entire cemetery was vast and boundless, with a total of four areas.

"This is where the elite army of the Demon King Army is buried."

Lu Ming said softly.

He could feel that there were probably thousands of corpses of more than 400 levels underground, and these people were the elite of a demon king army.

"Above...... Their names are also written......"

The saint crouched down in front of a tomb, glanced at the inscription on the tombstone, and found that it contained not only the names of the dead soldiers, but even the life stories.

"These people were the main fighting force in the battlefield in ancient times, and it is nothing to receive this kind of treatment after death."

Lu Ming didn't say a word in surprise, just glanced at a place with his eyes, couldn't help frowning, and walked over.

"Brave man, what's wrong?"

Seeing that Lu Ming was in a hurry, the saint also hurriedly followed.

It's just that she didn't finish asking, and her face showed a surprised expression, and she couldn't help but cover her mouth with her fingertips.

"The graves here...... How was it dug up? ”

I saw a huge grave on a high platform, and at this moment a pile of broken stone was piled outside, the coffin was exposed, and the body inside had long been gone.

Not only this place, Lu Ming looked around and found large graves in four areas, the corpses in which were all dug up, and even two other small graves were lost.

Seeing this, Lu Ming was relieved.

"There are six in total, it turns out that the demon bloodline that those people fused with is how they got it."

The coffin materials in the Demon King's Castle are all expensive, not to mention the corpses, even the blood inside is very fresh, and it is not impossible to take out the blood after being dug up and carry out the blood fusion experiment.

"It seems that the excavation of this Demon King City is not just the idea of the bloodline fusion experimenter in Renedi City, it should be the meaning of the black-robed man."

"It should be the black-robed man who first discovered this place under the city of Renedi City, took out a few corpses, and then had the fusion experiment of the demon bloodline, and later ordered the person in charge of Renedi City to excavate this Demon King City."

Lu Ming guessed what the whole thing had happened.

But as soon as he finished speaking, the saint asked him with some doubts:

"But, Lord Brave, how did they break this castle's detection system?"

"Didn't you say that as long as the system was there, the castle would be impassable?"

There are indeed many enchantments and magical barriers in the castle, and if the detection system is still there, unless it is really the castle's insiders, they will not be able to pass through these barriers.

Even the insiders have different access permissions, and except for the Demon King, everyone else can only pass under a part of the barrier.

As for outsiders, they can't even enter the teleportation array at the city gate, and the ghost knows where that teleportation array will directly transmit them.

"If it were anyone else, it wouldn't have been able to get in."

Lu Ming narrowed his eyes, remembering the person from the Holy Sword Church he had once met, and told the Holy Maiden:

"But those black-robed people do have a way."

They used to be able to walk through even the barrier of the goddess, how could it be difficult to live with them on the barrier of a demon king's castle?

But thinking of this, Lu Ming recalled the black needle used by the people of the Holy Sword Sect.

I don't know what that thing is, even the goddess barrier can break through, but then the black needle seems to have fallen into the hands of Anta?

At that time, I forgot to check its properties, so I threw it to Anta to study, and it seems that the next time I meet Anta again, I will have to take a good look at that thing.

"Let's go, there's nothing to see here."

Lu Ming left the excavated tomb without looking back, so that the holy woman didn't react a little, but she still followed honestly.

When he arrived at the spiral staircase, Lu Ming repeated his old trick and directly swept away the corpse of the entire fourth floor.

There are a total of 4,000 corpses of level 400, Lu Ming calculated that about every twenty corpses can allow him to be upgraded by one level.

Upgrading to level 1099, it only took more than six hundred corpses, but after Lu Ming tried to break through to the upper limit of level 1100, the corpse energy suddenly decreased by a hundred.

It seems that after level 1100, it is another small rank, and if you want to upgrade at this level, corpses below level 400 are useless.

Even if it is a level 400 corpse, it takes a hundred corpses to upgrade to the next level, and the demand is a bit terrifying.

After using up all the remaining corpses, Lu Ming found that he had only reached level 1130, and there was a faint feeling of powerlessness, I am afraid that after level 1150, the difficulty of upgrading will increase.

After all, after level 1000, there is an unknown realm, Lu Ming doesn't know if there is a sixth turn above level 1000, that is, level 1200, but according to his progress, I'm afraid it is impossible.

However, the rapid increase in the difficulty of upgrading has brought endless power to Lu Ming, and now there is almost nothing he can't do.

Even if it was the previous exile space, he could go in and walk around casually.

"It's a pity that the most important corpses above level 600 on the fourth layer have been taken for experiments, and the incomplete corpses that have lost their blood can no longer be devoured, otherwise I can be promoted to another level."

Lu Ming had some regrets about this.

He knew that there were not many corpses left in this Demon King Castle, and even the Demon Elite had been eaten by him, and except for the Demon King, I am afraid that there were no other Demon powerhouses left.

Next, Lu Ming and the Holy Maiden came to the fifth floor of the Demon King's Castle.

But after just one glance, they went straight to the next floor.

There are some ladies and maids here, and there is nothing to look at, among them, there are not even strong people above level 400, and Lu Ming and the holy maiden did not stay here for long.

The sixth floor of the Demon King's Castle.

Lu Ming and the Holy Maiden took the first step out of the spiral staircase, and they felt that this floor was suddenly much smaller.

At the same time, a gate like a moat appeared in the eyes of Lu Ming and the Holy Maiden, there was almost no boundary, even so, Lu Ming gently pushed it, and still opened it.

With a piercing creaking sound, the two doors stepped back, and blinding golden light suddenly flew out of the doors.

The saint on the side hurriedly tilted her head and covered her eyes.

Lu Ming also squinted, glanced at the scene inside the door, and said softly:

"Have you arrived at the treasure vault of the Demon King's Castle?"

What appeared to them at this moment was gold and treasures everywhere.

Although these things have only one function, that is, money, it has to be said that this is also the most precious thing in the entire continent, with them, no weapons can be bought.

Unless it's a weapon that the mainland doesn't have.

Under the saintess's surprised expression, Lu Ming waved his hand and put away the golden light all over the place, leaving a pile of high-grade equipment, but he didn't move.

These things are useless to him, and he has no shortage of equipment, so he is too lazy to get them.

"You want to see the equipment here, is it suitable for you?"

Lu Ming turned around and asked the holy woman.

Most of the treasures that can be stored in the Demon King's Castle are equipment above level 800, and when they are usually rewarded, they are directly rewarded to the generals.

Demons below level 600 are not eligible to be rewarded.

If the Holy Maiden can choose a weapon with a comparable degree of fit, then her strength will also have a drastic change.
