As he pondered, the sky suddenly became darker.

A rumbling sound of thunder came from afar, deafening.

A thick black bolt of lightning pierced the void, like a giant axe that split through darkness and slashed into the distance.

"Oops! This time came the storm. Leon's face changed drastically, and he hurriedly jumped onto the canopy of another towering tree.

Dark clouds were gathering and strong winds were raging.

The entire cave was instantly plunged into chaos.

Leon lay on his stomach in the treetops, holding his breath and waiting for the rainstorm to come.

Click-

Thunder and lightning flashed, lightning pierced the darkness, and raindrops the size of beans crackled and fell densely, drenching his clothes in an instant.

"This Nima ......"

Leon gritted his teeth, eager to pierce a hole in the sky.

The torrential rain washed over the caves, stirring up countless water mist.

Leon curled up on the branches, silently enduring the storm.

He was already very embarrassed, but now he was soaked in the torrential rain and turned into a soup chicken, uglier than a beggar, and looked quite funny.

Leon raised his head and squinted his eyes, observing the changes in the sky.

Dark clouds obscured the moon, winds howled, and torrential rain poured.

Leon could clearly see that the rainstorm was mixed with a faint amount of dust and falling down.

A wonderful red glow slowly drifted from the storm and fell into his arms, gradually blooming brilliant flowers.

"Huh? This is...... Blood Lotus?! Leon's eyes widened.

The Blood Demon Lotus is an auxiliary material for alchemy, and the price is extremely high, which can be encountered but not sought.

"Hahaha, I've made a lot of money now!" Li Ang was overjoyed.

This bloody lotus is of extraordinary beauty, with pure petals and stamens full of essence and vitality, and it is definitely a precious treasure.

The Blood Lotus has a total of seven petals, and each petal contains a different vitality, which belongs to the five elements of the elements.

Among them, the wood system is the most abundant, and the earth, gold, and water systems are somewhat lacking.

"Since it's the main material for refining 'Tsukidan', then I'm definitely not welcome."

Li Ang rubbed his fingers and couldn't wait to open the furnace to practice Dan.

But......

What about the materials for alchemy?

He turned his head to look around, and found that half of the ancient carved jade staircase was faintly revealing in the depths of the cave, leading to an unknown place.

"Could it be that the alchemy room is built behind the stairs?" Leon was silent, hesitating to go up and explore.

Just as he was struggling, he suddenly felt the rune tattoo on his right arm tremble, as if it was resonating with something.

"There is a situation!"

Li Ang's mind moved, and he immediately followed the message transmitted to him by the rune seal.

"Near here...... What's there? Leon frowned in contemplation and walked down the stairs.

Soon, he stopped, his eyes widening slightly, and a look of surprise appeared on his face.

"This is ......" Leon's vision presents a huge palace, majestic and majestic, and the atmosphere is grand.

This hall occupies an extremely wide area, up to 100 zhang, and the surrounding walls are also several meters high, which is very magnificent.

"This palace looks a little old...... "Leon rubbed his chin, "could it be ......"

Li Ang took a step and walked towards the main entrance of the main hall.

The door opens open, revealing a spacious and bright space inside, with dozens of cylindrical pillars on both sides, and a huge night pearl inlaid at the top, illuminating the hall to the fullest.

Leon looked left and right, his gaze finally falling on the front, the corners of his mouth sketching a mysterious smile.

He walked into the main hall and reached out to touch the white bone altar in the center of the main hall.

Airplanes~

With a low roar, the altar lit up.

The skeleton battle spirits opened their eyes in unison, and the dark green flames burned deep in their sockets.

The skeleton soldiers drew their swords one after another, roaring and roaring, and pounced on Leon with murderous vigour, opening their shriveled lips and revealing their sharp fangs.

"Hehe, see you again."

Leon smiled contemptuously and waved his hand to release the fireball technique.

Wisps of flame erupted, entangled the skeletons, and burned to ashes.

Immediately afterward, he unleashed flaming arrows that shot more than a dozen skeletons into holes.

"It's not bad, at least this bunch of garbage didn't bother me too much......"

Li Ang clapped his palms, and was about to continue to search for all kinds of materials needed for alchemy, but he was suddenly stunned.

He found that in the flames and smoke, the corpses were scattered on the ground, sitting or lying, and there was a trace of ominous breath revealed.

Most of the corpses were charred, their chests cracked open and thick blood flowing; Although the few corpses were well preserved and their muscles were still intact, they still had an astonishing smell of death.

"Corpse poison?"

Li Ang raised his eyebrows, and a glimmer of excitement flashed in the depths of his eyes.

He had long heard that the corpse clan fed on blood and devoured the corpses of humans and demon beasts to increase their strength, but he had not seen it with his own eyes.

Tonight I was finally able to open my eyes and see for a long time.

Hulala~

A large amount of gray dead air escaped from the depths of the hall, swirling in the air, turning into an invisible vortex and stirring up the torrential rain.

This breath carries a chilling death threat, like a shackle that cannot be broken free, firmly trapping the intruder.

Li Ang suddenly felt a coolness penetrate his skin, and sweat broke down his spine.

"It's horrible death...... Who died here, exactly? He muttered to himself, cold sweat forming into his forehead.

This kind of death threat, even a Qi Refining Stage cultivator would not dare to be careless.

Leon stared at the altar in the middle of the hall, his eyes gradually becoming hot.

His guess was correct, it was indeed a tomb, where ancient ruins with a long history were buried.

In the center of the altar stood a large stone axe with a sharp blade engraved with dense obscure charms.

Next to the stone axe, there was also a thick layer of mud and dirt, like the marks left by the decomposition of many corpses.

"Huh...... How so? ”

Li Ang frowned, raised his hand and grabbed the dirt next to the altar to examine it carefully.

"What a dead air!" Li Ang's pupils contracted suddenly, and he gasped, "This mud...... At least dozens, if not hundreds, of people were nailed alive to this altar! ”

Li Ang's heart suddenly swelled with monstrous waves.

He had just glanced at it casually, and he had already seen more than a hundred skeletons.

Such a terrifying scale of death is simply a sign of annihilation!

The more critical question is, is this altar still intact?

Leon searched carefully with his psychic sense, and finally confirmed that he did not find any danger.

He stood up and looked at the wall on the side of the altar.

On that wall, a vivid picture hangs.

It was an emperor wearing a dragon robe and a nine-tin shirt, with a burly and strong body, majestic and domineering, overlooking the vast land and dominating the four seas.

Li Ang's eyelids jumped, the appearance of the emperor in this painting was exactly the same as a certain prince he had seen.

"Do you mean ......?"

Li Ang stared at the portrait and muttered to himself, "This emperor is the Marquis of Wu'an I once met?" ”
