Inside the underground maze.

When the Undead warriors completely lost their sense of direction, Lin Hao had already walked out of the maze with the help of the map.

His vision suddenly became wider.

That scene seemed like another world.

Deep in the vast plain, the light was distorted, and there was a huge dark red palace standing faintly.

Perhaps because it is very old, the buildings on the surface look a bit dilapidated.

Seeing this, Lin Hao's eyes flashed.

This should be the underground palace that those undead warriors mentioned earlier.

The core area of ​​the treasure map!

At this moment, Lin Hao's speed suddenly increased.

As the distance got closer, the scale of the palace became clearer in sight.

The outer walls are all built with fire crystals, and the surface is covered with various strange totem reliefs.

These totems are not so-called flowers, plants, or monsters.

Instead, it was a large group of hideous demons, each with a red face and fangs, holding sickles and axes, and their strong bodies were wrapped in thick iron chains.

That appearance looks extremely wild and ferocious!

"The Flame Demon Clan?"

Seeing this, Lin Hao's pupils shrank slightly.

Since traveling to this era, he has obtained the record book "Encyclopedia of Races" from Wei Jiyuan.

The information on each race in the Sky Continent is extremely comprehensive.

The information about the Flame Demon Clan contained therein is almost the same as the totem images in front of us.

As for the winged demons encountered in the ancient battlefield, they are called the "Sky Demon Clan".

Among all the demon branches, the Flame Demon Clan is the most powerful.

However, he later fell, and the leader of the demon clan was completely replaced by the heavenly demon clan.

"How could the Flame Demon Clan build a palace in this underground space?"

As Lin Hao thought about it, he couldn't help but feel a little strange.

Moreover, the outer walls of the palace are all closed buildings.

Even though Lin Hao sent Jing Ke and the Mantis King to check around twice, they still didn't find any entrance to the palace.

In response to this, Lin Hao's eyes darkened slightly. It seemed that the only way to gain entry was to resort to violence.

At that moment, spiritual energy surged throughout his body.

Bang!

The fist exploded the air and slammed into the wall with an extremely terrifying vibration force.

However, this powerful force, which was enough to blow up a mountain, was like mud falling into the sea when it hit the wall, without any echo at all.

Buzz——!

Then, densely packed mysterious runes suddenly appeared on the walls of the palace, emitting bright red light.

It was as if it had absorbed all of Lin Hao's punching power.

Then this force actually bounced back and directly knocked Lin Hao flying backwards.

He fell heavily to the ground immediately, and the blood in Lin Hao's body churned violently, and he almost vomited blood.

"It turns out that there is a formation set up inside it."

Lin Hao stood up panting, grinned, and looked at the palace walls covered with runes, a hint of surprise flashed in his eyes.

Thinking back to the rebound force just now, this seems to be a defensive and offensive formation.

No matter how strong the force is, it will be absorbed and then bounce back.

Unless, the energy released instantly is powerful enough to burst the formation.

But with Lin Hao's current level of cultivation, it is obviously impossible to do so.

"There's movement!"

The sound just now undoubtedly attracted the attention of the undead warriors in the underground maze.

"Could there be other alien races that have broken in here?"

When he was puzzled, the leading member of the Dead Clan frowned.

If this is the case, then the several companions who were previously arranged to guard outside must have been killed!

Thinking of this, his gloomy eyes became even colder.

"Go that way!"

At that moment, the leading Undead warrior led his many subordinates to look for the source of the sound and determined the direction to move forward.

Outside the palace, Lin Hao stood silently, glancing at the maze area behind.

He guessed that the noise just now had most likely attracted the attention of the group of undead warriors.

Under the current circumstances, we must rush into the palace and obtain the treasure before they arrive!

"Jing Ke, you try it."

Lin Hao gave the order as his mind raced.

Jing Ke nodded his head and performed instant teleportation.

Its tiny body suddenly disappeared from the spot.

Buzz!

However, the next moment, the runes on the wall flashed violently, shocking Jing Ke who was about to pass through the wall.

Jing Ke did not give up and used teleportation again.

Buzz! Buzz! Buzz!!

After dozens of attempts, Jing Ke failed to successfully penetrate.

Even if the position is changed, the result is the same.

Seeing this scene, Lin Hao was slightly surprised.

Obviously, he didn't expect that even teleportation couldn't penetrate it!

"We finally found the underground palace!"

At this moment, a cold voice suddenly sounded.

Then, they saw that the group of undead warriors had appeared in the rear at some point.

Looking at the huge palace in front of them, their eyes flickered with excitement that they could not hide.

Immediately, the eyes of dozens of Undead warriors changed, and they looked at Lin Hao with cold gazes like wild wolves in the dark night.

"Lizardman?"

When the Undead warriors saw Lin Hao's dragon-man form, a hint of surprise flashed in their eyes.

After taking a closer look, I felt that its appearance seemed to be significantly different from the lizard I knew.

"How did you get here?"

The leading Undead warrior asked in a gloomy voice.

Lin Hao stared at the other person with a cold expression, thinking secretly.

These guys were able to gather the treasure map fragments together and mobilize the two mountains of thunder and fire to open up the underground passage.

I guess they also know how to open the entrance to this palace!

And the clues must be related to the information on the treasure map.

With a sudden thought, Lin Hao took out the piece of treasure map and turned it over.

However, there were indeed some fragments of runes marked on it, which seemed to be the "code" to open the seal of the underground palace formation.

"That's... the last piece of the treasure map!"

Upon seeing this, the Undead warriors suddenly widened their eyes and stared at the piece of treasure map in Lin Hao's hand with surprise.

"Hahahaha... it's really like searching for something unsuccessfully, but now it's found without any effort."

The leader of the undead tribe finally couldn't hide his excitement anymore and laughed in a sharp and strange voice.

He immediately changed the subject and said coldly, "Lizardmen, if you know what's best for you, hand over the treasure map fragments obediently."

"Otherwise, with the methods of our Death Clan, we will make you live a life worse than death."

After saying this, he let out a sinister laugh and stretched out his bony hand.

The cold mental power quickly condensed and suddenly formed a ball of dark green light shaped like a flame, emitting a heart-pounding deathly aura.

"If I were afraid, I wouldn't be here."

Lin Hao smiled coldly, and a wave of spiritual power also emanated from his palm.

"If you dare to make a move, this treasure map fragment will turn into ashes in an instant."

"If you don't believe me, you can try it."

As soon as he finished speaking, the fragments of the treasure map in Lin Hao's palm slowly spun on his palm in the turbulent flow of spiritual energy.

As long as he thought about it, he could crush it to pieces in an instant.
