I saw that in the huge underground palace, tens of thousands of demon cores were placed, whether it was a first-order demon core, a second-order magic core, or a third-order magic core...... It's all piled up into a small mountain!

Among these demon cores, there are more than a hundred seventh-order demon cores, and there are nearly a thousand sixth-order demon cores, and those high-level demon cores and low-level demon cores, not to mention, the total amount adds up to at least a full 200,000!

I don't know, how long has this Black Iron Fort been stored before accumulating so many magic cores, storing them in the underground palace and using them for cultivation!

With such a large number of demon cores, several Saint Emperor powerhouses can be piled up.

"Original...... This is the treasure of the Black Iron Fortress?"

A trace of excitement flashed in Luo Chen's eyes, and he said in surprise.

"Unexpectedly, this Black Iron Demon Emperor has collected so many demon cores?"

Yun Aorou raised her eyebrows, her eyes flashed with a hint of joy, and then she said slowly: "Luo Chen, quickly collect these demon cores, in case they are seen by others, it will be a big trouble!"

Although these magic cores were invaluable, Yun Aorou did not have a trace of possession, but planned to give them all to Luo Chen, after all, even if these demon cores were very precious, compared to the Immortal Spring Spiritual Liquid, they were much worse in level.

In order to express her gratitude, it is reasonable for her to give up these magic cores.

"Okay, then I'll collect these demon cores first, and then distribute them after I have won the three demon cities. ”

Luo Chen didn't twist it, but with a wave of his hand, he put all these magic cores into the storage ring and stored them in the storage space.

However, the number of these magic cores is too much, and some of them can't fit just a storage ring.

With an idea, Luo Chen simply took off the storage ring from his finger and put it into the Chaos Tower, poured out all those magic cores, turned them into a demon core mountain, and placed them in the first layer of the Chaos Tower!

As a treasure of the Demon Race, the Chaos Tower not only has a wide space, but also has the ability to control time, so it is also a good choice to exist in the Chaos Tower!

Then, Luo Chen put the storage ring on his hand again, and couldn't help but secretly think in his heart, now that he has more and more things, should he change to a bigger storage treasure?

Before he had time to think about it, Yun Aorou said softly: "Luo Chen, the Black Iron Castle has been solved, there is still the Fallen Abyss left, the Extreme Demon City, which one shall we sweep first?"

"Sweep away the fallen abyss first, the Extreme Demon City is the most powerful demon force in the Iron and Blood Demon Domain, if it is swept first, it will definitely startle the snake!"

Luo Chen's eyes flashed and he suggested.

"Okay, then choose the fallen abyss!"

Yun Aorou nodded, with a hint of disdain in her voice, as if taking off a demon force was a matter of course, a trivial matter.

In fact, don't look at the Iron Blood Demon Domain, it is thousands of miles wide, but in the Star Empire, it is just a small man, if it is not for the inheritance of the Iron Blood Demon Emperor, I am afraid that in this area, even a Demon Emperor will not exist!

Therefore, if you want to sweep the entire Iron Blood Demon Domain, it will naturally be easy.

"Let's go, use the fastest speed to solve the abyss of depravity!"

Luo Chen said excitedly.

With that, the two of them rose from the underground palace and rushed to the abyss at an extremely fast speed, and even the reaction time was not prepared to be left for these demons!

...... Two hours later.

Buzzing!

With a burst of sky-high blood, it spread out from the abyss of depravity, and the entire abyss was full of demon corpses, as well as weak soul bodies, floating in mid-air.

Not only that, but in the Soul Suppression Bead, there was also an extra Saint Emperor-level Divine Soul, roaring wildly inside, constantly colliding, and full of anger.

It's a pity, no matter how sad and angry this Saint Emperor-level Divine Soul is, it can't escape the confinement of the Soul Suppression Bead, and it was brutally suppressed and defeated.

And this divine soul is none other than the Fallen Demon Emperor - Demon Wutian!

At the same time, among the Chaos Tower, there is an extra demon core mountain, although the number may not be as good as the Black Iron Castle, but the sum is also very considerable.

"Unexpectedly, it only took two hours to sweep away the abyss of depravity!"

Luo Chen held the Soul Suppression Bead in his hand, stood above the abyss, and said with satisfaction: "Not only that, but we have also obtained so many divine souls, as well as the treasure of the fallen abyss......"

"Let's go, continue to kill towards the Extreme Demon City, since the Iron Blood Demon Emperor is no longer there, there is no need for these demons to exist. ”

Yun Aorou said calmly: "If you keep it, it will only become a scourge and threaten the Star Empire, it is better to kill it as soon as possible, so as not to increase the disaster!"

"Okay, then we will continue to kill towards the Extreme Demon City, however, the Lord of this Extreme Demon City is a Holy Emperor Fifth Heaven Existence, we must be careful!"

Luo Chen reminded, don't look at him killing the Heaven Devouring Demon Emperor, but the existence of the Holy Emperor Five Heavens is also a very difficult existence, if you don't use the spirit rune, I'm afraid that with just flesh and blood, kill a Holy Emperor Five Heavens, or a demon powerhouse, it's almost impossible!

As he spoke, Luo Chen flipped his palm, took out two divine hidden talismans, and handed one of them directly into Yun Aorou's hand.

"It's ...... Invisibility talismans?" Yun Aorou said in surprise.

"Although the effect is similar, however, this is not an invisibility talisman, but a divine concealment talisman. ”

Luo Chen said with a smile: "As for the power, you can try it?"

"Hmph, isn't it just the art of the seal, is it...... Can this spirit rune still isolate the detection of the Holy Emperor's powerhouse?" Yun Aorou chuckled, and then with a slight force in her jade hand, she crushed the Divine Hidden Talisman and turned it into a white light, which blessed her delicate body.

Suddenly, Yun Aorou's whole person, without using Yuan Force, also merged into the heaven and earth, and entered a transparent state, even if it was a Holy Emperor powerhouse, it was difficult to detect.

"Huh?"

After a slight sense, Yun Aorou immediately snorted and said in surprise: "Is it really invisible?" If you didn't know it in advance, you wouldn't even be able to detect it." ”

As soon as the words fell, two taps suddenly came from Yun Aorou Xiangxiang's shoulder, and Luo Chen didn't know when, but also entered a state of invisibility, even Yun Aorou didn't know, only when Luo Chen touched this girl, she could perceive it.

If it was someone else, he dared to touch his fragrant shoulder, but he was afraid that he would have been slapped to death by Yun Aorou with a palm, but if it was Luo Chen, this girl raised her eyebrows, and she was pretty and angry, and said in surprise: "Little villain, what kind of charm are you, why are you so magical......

For Luo Chen, Yun Aorou is becoming more and more curious, this guy seems to be full of mystery all the time, making her elusive. Even the spirit rune of the Divine Hidden Talisman, Luo Chen can have it, which undoubtedly shows that he is by no means an ordinary person!

Could it be that Luo Chen also has some mysterious inheritance?

"Hehe, it's just a little trick. Luo Chen said with a mysterious face, even if Yun Aorou was curious, he couldn't say that Luo Chen couldn't tell the Holy Demon Lord that this talisman came from the earth, and there was no one in this world?

After all, this is Luo Chen's biggest secret, how can he tell others?

"Okay, since you don't want to say it, then I won't ask. ”

Yun Aorou is a smart woman, since Luo Chen didn't say it, she didn't ask much, but her eyes flashed with murderous intent, and she said coldly: "Let's go, if those demons in the Extreme Demon City get the news, if we want to sneak in, it will be troublesome." ”

"Okay, let's go immediately and kill the Extreme Demon City!"

Luo Chen agreed.

Whew!......

As the sound of two shuttles sounded, the two of them did not hesitate, and in a state of invisibility, they left the abyss of depravity and went to the Extreme Demon City.

There is only a large amount of blood and qi, fluttering with the wind, like the Nine Shades Purgatory.

Of course, before leaving, Luo Chen didn't forget to take away all those iron-blooded demon spirit souls, turn them into a trace of black gas, and store them in the soul suppression bead.

......

Extreme Demon City, in the main hall.

"Damn, what's going on lately, why do I always feel restless?"

I saw a black-robed man, sitting on the throne, drinking and scolding.

In his arms, there are two beautiful female demons, sitting on their laps, both in appearance and figure, they are superb, even if they are placed among human beings, they are also unique, upside down the existence of all beings.

It's a pity that these two beautiful female demons, like slaves, are cautious and obedient, no matter how vicious the black-robed man is, they serve carefully.

And this black-robed man is the lord of the Extremely Evil Demon City, the Demon Town Prison!

Suddenly— "Huh?"

Suddenly, with a strange fluctuation, Demon Town Prison frowned, couldn't help but look at the door of the main hall, frowned and shouted: "Who is there! Get out of here!"

Rumble!

As he spoke, he grabbed the wine glass, shook it vigorously, turned into a silver streamer, and smashed it towards the door of the main hall!
