But Leon always felt that the black skeleton's lair was not as peaceful and safe as it appeared on the surface.

He hesitated for a moment, then turned and walked towards the black skull's cavern.

Leon didn't believe that the black skeleton would dare to openly attack the ruler of the underworld.

He ran wildly, faster and faster, and suddenly a wide open space of black and brown appeared in front of him.

The ground is covered with solid rock formations, and in the distance there is a huge mountain peak, more than a thousand feet high, as if it were holding up the whole hell.

There are many strange buildings built on the mountainside, including altars, houses, palaces, altars, and huge iron prisons, which are sealed with countless evil spirits.

Leon looked at these familiar and unfamiliar scenes, his heart beating violently, and his breathing was short.

"This is, the Alchemy Workshop."

He muttered to himself, and finally realized that the black skeleton was leading him to the alchemist's lair!

The black skeleton seemed to be very jealous of the alchemy workshop, and did not dare to go deeper, so it wandered outside, roaring hoarsely and angrily.

Li Ang no longer hesitated and climbed up the stairs.

This alchemy workshop occupies a large area, and the walls are inlaid with bright night pearls that illuminate the empty underground.

The giant pyramids are neatly arranged, forming complex and cumbersome alchemy patterns, outlining a simple and solemn magic array.

These magic arrays contain powerful spell energy, which are linked to each other to form some unknown power, outlining twisted and changing lines and lines in the void, intertwining with each other and condensing all kinds of magic arrays.

Leon's heart pounded and twitched uncontrollably.

"These are...... Teleportation Circle? ”

He looked at the alchemy pattern in shock.

In the Demon Dao Star Domain, the level of the magic array is the same as the spell model, which is [Ordinary Circle], [High-level Circle] and [Extraordinary Circle].

The Ordinary Circle is a basic spell model created by the first generation of magic apprentices.

A high-level magic apprentice has mastered high-level spells and can cast extraordinary spells, which are transcendent magic circles, and have extremely powerful destructive power.

Legendary mages, demigods, and gods will leave their mark on the magic circle, allowing future generations to inherit the mantle, teach new spells or magic weapons, or improve their strength.

If the magic array created by the legendary magic apprentice can be completely penetrated, even the roughest [teleportation array] will be enough to tear through time and space and open the gap between the two realms.

But to fully comprehend legendary spells, it takes a long time and consumes a lot of resources.

When Li Ang was in the Demon Dao Star Domain, he had studied legendary magic, but he never understood the essence of the legendary magic circle.

Now, he witnessed with his own eyes the legendary magic array engraved in the alchemy workshop, stirring with majestic and vast power, as if containing the mysteries of the universe and the galaxy, filled with endless mysteries, which made him intoxicated.

"What's wrong with the world?"

Leon muttered to himself blankly, "Why is there magic? My ancestors were wizards, but they only knew how to use wands and cast simple spells.

Now, there is actually an alchemist who can set up a magic circle?

Could it be some magister? Or ......"

Leon shook his head, shook off his chaotic thoughts, and continued to search for traces of the black skeleton.

He walked around the alchemy workshop, scouring every inch of the building, but found nothing.

"Strange, where the hell did the black skeleton get me?"

Leon stood on the edge of the alchemy pattern, looking up at the pitch-black sky.

In his field of vision, the sky was covered with blood-red spots, as if it was soaked in blood, giving people an inexplicable sense of fear.

The Black Skull's lair is located at the foot of the mountain, some distance from the city, but the surroundings are dark and empty, except for the Black Skull on the top of the mountain.

"Forget it, let's go explore the city first."

Leon sighed and leaped over the steep ridge of the hill and into the streets of the underground city.

His legs were limp, his face was pale, he was sweating profusely, and he couldn't breathe.

The city was so big that the map he drew from memory was only a part of the underground.

The underworld is a labyrinth, full of forks in the road, terrifying dangers, and deadly traps waiting for intruders.

Leon didn't dare to stop, chasing after the scent of the black skeleton.

It wasn't long before he came to the front of a large and grand hall.

The hall is surrounded on all sides by heavy stone pillars, topped with lifelike dragon heads, mouths open, spitting out suffocating black smoke.

In the thick smoke, the faint sound of ghosts wailing sounded creepy.

"Roar—"

The black smoke suddenly rippled like waves, and a black skeleton poked its head out of the black smoke, its scarlet eyes stared at Li Ang, and a series of weird chuckles sounded in its throat, stretching out its bone claws, and grabbing him.

"Get out of here!"

Leon let out a loud shout, and his left arm swung like lightning, slamming into the skeleton's neck.

Rumble!

The skeleton staggered backwards, smashed into a wall, and fell to the ground.

Immediately afterward, its body rapidly expanded, becoming more massive and burly, and its hideous features gradually dissipated, turning into a sturdy and tall man, wearing pitch-black armor and wielding a gun and shield.

Leon recognized the other party and exclaimed, "You are the skeleton general, the black skeleton?" ”

The black skeleton gave him an indifferent look, and walked to the other side, and a tall and mighty skeleton general slowly walked out.

The two skeleton generals came together, one left and one right blocked Li Ang, and raised a huge fist like steel bars and smashed it down.

Li Ang was already ready, his right hand clenched into a fist, and he met the fist of the black skeleton general.

"Bang!"

In the muffled sound, Li Ang's fist and the skeleton general's fist touched, and there was a loud noise, but instead of a firelight, a pale golden halo bloomed.

"Huh?!"

Li Ang's eyes widened, "My physical quality has increased by 10%!" ”

The Black Skull General's fist and his fist shook hard, but the effect was 10 times more than his brute force alone, directly bursting out with 10 times the damage!

He instantly realized what the problem was, "This is the power of the 'Sanctuary'!" ”

"Ho-ho-ho!"

The two skeleton generals laughed strangely, and their fists smashed down like a storm, like a thunderbolt.

Li Ang swung his sword to resist, but the attack of the two skeleton generals was incredibly fast, forcing Li Ang to adjust the collective True Yuan in order to barely parry.

After a short stalemate, Leon was suppressed and passively defended, and soon showed fatigue and was knocked away by the skeleton general's elbow.

The skeleton general did not give up, continued to pursue, and slammed a punch into Li Ang's chest and abdomen, Li Ang raised his knife to block, but to no avail, his ribs were broken three times, a mouthful of blood mist was spewed, and he fell to the ground.

Without hesitation, the two skeleton generals pounced on his head and throat.
