The process of clearing the Demon Castle is simple and smooth.

Under the command of a demon lord, there are usually more than 100,000 demon subordinates of all levels, of course, the number of demon generals and big demons is not very large, most of them are demon warriors and small demons. As for the inferior demons, they are the lowest cannon fodder, coolies, and even food, which are not regarded as the same clan by the superior at all.

Qin Feng didn't need to do it himself, he summoned a group of steel elemental puppets and killed all the demon forces left behind in the palace, and threw all the demon corpses into the dimensional space to be sent to the starship for decomposition and digestion.

“…… is worthy of being a demon lord, and his family background is rich! ”

When several beautiful succubi led him to the treasure house in the depths of the palace, Rao was sitting on a huge amount of wealth, and Qin Feng still sighed at the mountains of treasures in front of him.

In the hall with a radius of tens of thousands of square meters, gold bricks and gold bars are neatly stacked into piles of hills, shining brightly.

There is no shortage of precious minerals in the abyssal environment, and the magma that gushes out of the ground is rich in metal elements, which will become immediate wealth after being refined and purified by the little demons.

In addition to a large amount of gold, there are also a variety of magical metals and crystals that can only be produced in the abyss, such as Abyssal Black Crystal Iron and Dark Demon Star Sand, which are very popular among legendary mages in the surface world, and are indispensable raw materials for creating high-level magic equipment.

Qin Feng casually opened a delicately crafted box in front of him, and inside was a very well-preserved medicinal herb. He thought about it for a while, and then remembered that this was the Demon Domain Blood Soul Grass, which could enhance the spiritual power of the legendary mage, and it was an extremely rare treasure, which could be used as a key ingredient for the preparation of high-grade alchemy elixirs.

In addition, there are some armor weapons, although the craftsmanship is average, but the material is quite good, get it back to enchant and process, it is very sophisticated equipment, even if it is returned to the furnace and refined.

Qin Feng made a rough estimate, the wealth here was worth twenty or thirty thousand high-purity magic crystals, and they could be exchanged for a rich duke on the surface. The environment of the abyss world is indeed extremely harsh and cruel, but it is not as barren as outsiders imagine, and all kinds of resources are actually quite abundant, but they are all controlled by the superior demons.

Moreover, the demon lords don't need to spend much money, and most of the wealth only goes in and out, and over time, the family background is naturally quite rich.

The light swept by, and the entire treasure house was suddenly clean and slippery, and not even a copper plate was left.

“…… Master, what shall we do?"

Several succubi looked at him with blank eyes, and said pitifully. Now that the lord is dead, only these succubi have survived in the entire castle.

"It's okay, it won't be long before a new lord will come to this place." Qin Feng said.

These succubi also look good, their strength and talent are very average, and he has no intention of accepting them. Anyway, there was plenty of food in the castle, and their survival was not a problem.

In the end, Qin Feng still left some belongings for them and left. Continue in search of the next Demon Lord's castle.

The speed of time passing in the abyss world was much faster than that in the surface world, so Qin Feng was not in a hurry, wandering around, patiently looking for targets, and then killing them by surprise.

With a huge amount of magic power, and an abundance of alchemy potions as a backing, Qin Feng could now kill two or three complete demon legions in one go, including the demon lord who led the team. Then they ransacked their castles.

In fact, he basically didn't have to face more than two demon legions at the same time, because these lords were not subordinate to each other, and due to the frequent conflicts and even wars between them, the relationship was very bad, and it was difficult for him to truly unite like human nobles, unless there was an order from a higher level lord.

Therefore, it didn't take long for Qin Feng to kill all the legions of the three-headed demon lords one after another, and then clean their castles. Whether it is the origin of the world or the wealth, the harvest is quite rich.

“…… In this way, it seems that it is not too difficult for legendary mages to make a fortune. Qin Feng muttered to himself.

When you are short of money to spend, come to the abyss world to take a turn, kill a few demon lords, loot a few castles, and you can have a large amount of money.

"Obviously, it's impossible,"

The starship center's calm voice sounded: "The rule power of the abyss world is very strong, ordinary legendary powerhouses will be significantly suppressed here, and the demon lords already belong to the class favored by the will of the abyss, and their strength will be strengthened to a considerable extent." With one plus and one subtraction, it is not as simple as imagined to kill the Demon Lord. ”

"You can make an exception because your ability is too strong, plus the effect of alchemy construction and equipment, otherwise it will be very difficult here."

Qin Feng's innate abilities, alchemy construction, and equipment are already at the top level, and there are really not many legendary powerhouses who can compete with him in this regard, so he can ensure that he is in a no-man's land here.

"It's just...... If the Demon Lord loses too much, it will definitely attract the attention of the Abyss Will, and it may not be long before you will be targeted by a certain Demon Great Lord. Starship Hub reminded.

Qin Feng's face changed slightly, the starship hub was not alarmist, this situation was bound to happen. The Demon Lord is not a sheep, and can be captured and slaughtered at will by foreign powerhouses. If the movement of his tossing is too big, he will not be able to make it happen, and many demon lords will unite to hunt him down.

And at this time, he had already noticed that the surrounding abyssal environment had faintly increased his sense of rejection towards him, thinking that it was because he had slaughtered too many demons, and he was disgusted by the abyssal will in the underworld.

"Okay, I know what to do."

Qin Feng didn't say anything anymore, raised his hand to draw a spatial portal in the air, dodged into it, and returned to his half-plane. He planned to repair and return to his peak state before going to the Abyss World.

This time, he did not spare his origin, and upgraded several abilities such as magic torrent, magic immunity, extreme control, and nightmare awakening to the extreme, plus the legendary alchemy potion that can temporarily increase the upper limit of magic power and magic damage, so that his strength has been raised to a new height, even if he encounters a demon lord at the super strong level, he can have the power to fight.

……

At this moment, in an area of the Abyss World, the magnificent and huge castle complex stretched for hundreds of miles, shrouded in a pale red light curtain with a faint golden glow, and on the surface this was a place blessed by the will of the Abyss.

In the huge square in front of the main building of the castle, thousands of great demons gathered here, as well as hordes of demon warriors, their armor and weapons glowing with bright magical brilliance, obviously much better.

The commander of this demon legion is a demon lord who has just been promoted to the legendary realm.

Enter the castle and ascend via a huge staircase, at the top of which is a magnificent palace hundreds of meters high, guarded by a greater number of demon warlords. There is no shortage of rare varieties such as Shadow Demon, Soul Eater, and Blood Demon.

In the huge hall with a radius of thousands of meters, on the high throne, a burly and handsome demon sat in contemplation, its appearance was almost no different from that of humans, its bearing was graceful and noble, if it were not for the large group of high-level demons of different forms standing below, it might look more like the lord of a human country.

The demon lords of the legendary realm all have the ability to adjust their body shape and appearance, so the more powerful the demon, the closer their appearance is to that of humans.

The demon lord quietly watched as the courtiers below reported on various affairs in the territory, and only occasionally asked a few questions. The demons who are asked will answer by kneeling on the ground in fear.

Heavy footsteps came from outside, and a dignified-looking demon priest strode in, knelt down towards the Lord on the throne, and said in a deep voice:

"My lord, the news just came that the four lords including Kadimon can no longer be contacted, and according to our speculation, they have all been killed!"
