The monster applauded and said with a smirk: "Welcome, welcome, I haven't seen a living thing for tens of thousands of years, and today I can finally relieve my boredom!"

When Leon saw this monster, he couldn't help but be taken aback. Because according to the monster book he has seen, this monster is clearly the devil in the hell of the demon world.

And this devil has reached a height of more than twenty meters, and it seems to be a devil lord.

Devils are divided into small devils, devils, great devils, devil lords, and devil lords according to their strength, corresponding to the mortal level, transcendent level, holy level, demigod and true god realm, respectively.

In other words, this devil in front of him has the strength of the demigod realm.

If this devil lord wants to kill Li Ang, I'm afraid that Li Ang has no chance to resist at all.

For a while, Li Ang's face couldn't help but turn pale, and he retreated again and again.

The devil lord suddenly smirked and said, "Hehe, you seem to recognize my identity, that's right, I am a devil lord, named Delem, who destroyed this floating city ten thousand years ago, but was also trapped here by Amelia, the magic spirit of the floating city!"

Leon's heart moved, and he said tentatively, "I heard that the devil is not a creature that likes to kill indiscriminately?"

Delem laughed mockingly and said, "That's when we weren't hungry, unfortunately, I've been hungry for 10,000 years, and our devil's recipe is the soul of you intelligent beings!"

Li Ang's face couldn't help but change when he heard this.

But at this time, Delem said, "However, if you can help me escape from here, I can spare your life!"

"Oh, you want me to help you escape?" Li Ang's eyes lit up when he heard this, and he seemed to see a glimmer of hope for escape.

After Leon used the portal to teleport in, the light gate of that portal quickly closed automatically, but Leon's auxiliary spirit should be able to open it again.

Draem nodded and said, "Yes, since you can open the portal to here, you can naturally help me escape, how about it, as long as you obediently help me open the portal, I will let you go, how about it?"

Li Ang frowned and thought for a while, and said, "But I heard that you devils are very cunning, what if you go back?"

Drym smirked and said, "We can sign a magic contract so I can't go back!"

Li Ang laughed when he heard this: "The most untrustworthy thing in the world is the devil's contract, and the devil knows if you have set any traps on it!"

Delem frowned and said, "This can't do that, you don't want to die, don't you?"

Li Ang said lightly: "I came here to obtain the mysterious knowledge of the ancient magic civilization, you have been here for so long, you should have collected all the books here, as long as you give me all those books, help me advance to the holy level, and then sign a magic contract with me, I will help you out, how about it?"

Drym rolled his eyes and said, "Okay, anyway, my magic is dark, and those books are of little use to me, so I'll give them to you!"

As he spoke, Delem wiped a belt around his waist, and immediately took out a pile of books and threw them on the ground.

Seeing this, Li Ang's eyes lit up, and he hurriedly used his mage's hand to pick up all those books, and then quickly flipped through them.

There were tens of thousands of books, and although Li Ang had auxiliary magic spirits, it took him half a day to finally memorize them all.

Soon, the auxiliary magic spirits began to consume evolution energy points, constantly deducing and analyzing the contents of those books.

The content of these books is varied, including magic, fighting qigong, martial arts, and some miscellaneous knowledge.

Due to the large number of them, the auxiliary magic spirits finally exhausted Li Ang's evolution energy points, and finally analyzed it thoroughly, and integrated the useful parts of it into the Shattered Void Fighting Qi.

The auxiliary magic spirit prompted: "Master, your Shattered Void Fighting Qi has been deduced to the perfect realm, and you can start cultivating!"

Li Ang nodded, found an empty room in the palace and sat down cross-legged, and practiced according to the new version of the Broken Empty Douqi exercise.

I saw that Li Ang first condensed the shattered void fighting qi into mysterious runes, forming a circular rune array.

Soon, Li Ang activated the rune array, which immediately caused the shattered void fighting qi in his body to continue to rotate, and finally formed a huge vortex of fighting energy.

Then, Leon began to channel the elemental energy around him and injected it into his body.

As soon as those elemental energies entered Li Ang's body, they were immediately swept into the whirlpool of fighting qi, and they were constantly squeezed and refined.

Soon, those elemental energies were refined into the most primordial spatial energy, and gradually merged into Li Ang's shattered void fighting qi.

Suddenly, the Shattered Void Dou Qi in Li Ang's body, which had already reached its limit, continued to swell again.

At this time, the auxiliary spirit said to Li Ang: "Master, you have advanced to the zero level of the holy rank, and since then you have an endless stream of energy, I can absorb your energy to replenish the evolution energy points!"

Suddenly, Li Ang felt a suction force emanating from the Shattered Godhead, sucking his Shattered Void Bucket Qi endlessly.

And his evolutionary energy points soared wildly.

Soon, the shattered void fighting qi in Li Ang's body was sucked away, but fortunately, he could absorb elemental energy from the outside world and quickly replenish it.

One day later, Leon's evolutionary energy point reserve had reached two million points.

"Master, you can consume two million Evolution Energy Points to raise your level to the first level of the Holy Rank!" the auxiliary spirit prompted.

Li Ang nodded, and immediately chose to upgrade.

Soon, he completed the upgrade, his level was raised to the first level of the Holy Rank, his full attributes were increased to forty-one, and he gained twelve free skill points.

Leon immediately put a little free skill point into his stealth skill, upgrading it to the fourteenth level of grandmaster.

The remaining eleven points were all invested in illusion magic skills, raising them to the twelfth level master.

The reason why it is prioritized to improve illusion magic skills and stealth skills is because Leon wants to restrain his breath, hide his strength, and prepare for escape.

Soon, Li Ang used the aura-constricting ability brought by the stealth skill to hide his aura deeply, still disguised as the realm of the peak of the transcendent level.

Originally, Li Ang still wanted to continue cultivating and break through to the peak of the Holy Rank in one fell swoop.

However, that Drame seemed to be in a hurry to wait, and spent all day urging Leon to quickly open the portal and help it escape.

Li Ang had no choice but to give up his plan to continue cultivating and began to implement his escape plan.

Soon, he cast a top-level phantom magic, the True Phantom, leaving a lifelike phantom in his place, and then used his stealth and stealth skills to sneak towards the portal to the outer city.

Eventually, Leon came to the portal without any danger.

Then, the auxiliary spirit once again emitted a stream of golden light, which continued to pour into the portal.

However, by this time, the Drame seemed to have noticed that something was wrong, let out an angry roar, flew out of the palace, and flew towards this direction at a gallop.

"It's not good, hurry up!" Li Ang was anxious when he saw this, and hurriedly and anxiously urged.

"The fastest can only be so fast!" said the auxiliary spirit lightly.

In the blink of an eye, that Delem flew less than a hundred meters away from Leon.

Fortunately, it was at this time that the auxiliary spirit finally succeeded in activating the portal and opening a door of light to the outside world.

Leon hurriedly dived in.

"Damn boy, stop me!" Drame burst into a shout and flew towards the light gate in the center of the portal.

However, at this time, Leon had already teleported out, and immediately ordered the auxiliary magic spirit to close the light gate.

As a result, Delem was blocked by the closed Light Protégé.

"Ah, damn human, you dare to deceive my Delem, I will never spare you!" Leon heard Delem's angry roar through the door of light that had not yet been completely closed.

"Hmph, I can't spare you, it's a scourge to keep you sooner or later, when I condense my divinity and advance to the demigod realm, I'll get rid of you immediately!" Li Ang muttered to himself.

At this time, the auxiliary magic spirit said to Li Ang: "Congratulations to the master for successfully advancing to the Holy Rank, with your cultivation speed, as long as you cultivate for another year and a half, you will be able to reach the peak of the Holy Rank!"

Leon nodded and said, "But I'm afraid I don't have so much time to cultivate, this Drame has already mastered the mysteries of the ancient magical civilization, and it is possible to break the portal at any time and teleport out of it, and I helped Princess Catherine destroy the Immortal Island, I'm afraid I have become a thorn in the side of the Dark Council and the Blood God Society!"

The auxiliary spirit said: "The master doesn't have to worry, there is no broken godhead, that Delem is not so easy to crack this portal, and the pursuit of the Dark Council and the Blood God Society, the master does not have to worry, as long as Princess Catherine helps you build the mage tower, you can have the strength comparable to a demigod in the mage tower!"

When Li Ang heard this, his eyes couldn't help but light up.

Indeed, the Mage Tower is comparable to an artifact for a mage, which can increase the casting distance of a mage to hundreds of kilometers and greatly increase the power of a spell.

So, Li Ang quickly boarded the floating spaceship and flew in the direction of the imperial capital at a gallop.

Soon after, Leon returned to the imperial capital and soon found Princess Catherine, expressing his eagerness to build the Mage Tower.

After listening to Li Ang's intention, Princess Catherine nodded and said, "Okay, hurry up and help you build the Mage Tower, and you can also strengthen the defense of the border as soon as possible, I'll go there myself!"

So, Princess Catherine called several court mages of the royal family and flew towards Leon's territory on a floating spaceship with Leon.
