"Although we are missing the most crucial map route, as long as we open the entrance, the treasures in the underground palace will undoubtedly be in our pockets."

The leading Undead warrior laughed grimly.

Immediately, he waved his hand and a rune jade slip floated up.

As it was activated, a layer of isolating light curtain instantly covered the area.

Outside the light curtain of the formation, several warriors of the Undead Clan were left to guard it in order to prevent the formation from being destroyed by the monsters active in the surrounding area, which would cause the entrance to be exposed.

As for the many other members of the Undead Clan, they all set off and rushed directly into the energy light gate, leading directly to the underground world.

"I can't slow down."

Realizing this, Lin Hao's eyes became slightly stern, and his body immediately moved like a nimble monkey, quickly shuttling through the mountains and forests.

However, at this time, the nearby area had been covered by the mental fluctuations of several Undead warriors.

They are aware of any disturbance.

"There's movement!"

The moment Lin Hao entered the range of their mental power, he was quickly discovered.

Buzz——!

All of a sudden, several cold mental forces formed a soul attack, targeting Lin Hao and rushing forward at the same time.

Lin Hao's eyes instantly turned into black and white whirlpools.

Reincarnation Martial Intent!

The moment it was triggered, all those soul attacks were blocked, and a counterattack was launched along the trajectory of the opponent's mental fluctuations.

“Ahhhh!!”

Immediately, several screams were heard.

Those undead warriors all suffered the soul attack of the reincarnation martial spirit.

"Jing Ke, kill!"

Lin Hao's eyes turned cold, and without any hesitation, he gave the order directly.

whoosh!

Jing Ke, who had been ready for battle, immediately started killing.

Its speed is so fast that it is like the god of death reaping lives at night.

After a few quick flashes, the several members of the Undead Clan fell to the ground and died without exception.

The whole process was fast, fierce and accurate, fully demonstrating Jing Ke's ability as an 'ace killer'.

Immediately, Lin Hao stretched out his hand, and Jing Ke obediently flew onto his palm.

Teleport.

The next moment, the man and the beast disappeared at the same time.

Directly penetrate from outside the light curtain of the isolation formation.

Looking at the energy light gate in front of him, Lin Hao waited for a moment before rushing in.

After a brief trance, what came into Lin Hao's sight was a dim passage.

The entire passage extends diagonally downward, apparently leading directly to deep underground.

In order to avoid making any sound of footsteps, Lin Hao's figure was floating in the air along the way.

Jing Ke was standing a dozen feet ahead, responsible for clearing the way to prevent an ambush by the undead warriors.

There was no unusual sound in the silent passage.

The stone path was extremely long. It took Lin Hao more than an hour to walk forward, but he still hadn't reached the end.

Gradually, the passage became steeper and the air around became hotter.

A red wave of air rushed towards him, and waves of scorching energy instantly swept through his body.

"Such a rich fire energy!"

Lin Hao was slightly surprised.

He immediately mobilized a spiritual power to form a protective spiritual shield to cover his body surface, directly blocking the scorching air waves.

If an ordinary person were to get in here, it would be difficult for him to survive.

"Bang!"

At this moment, a dull sound suddenly came from deep in the passage.

Lin Hao stopped and looked alert.

Jing Ke showed no fear at all and immediately flew deep into the water, but he did not find anything unusual.

In this regard, Lin Hao did not intend to stay here, but continued to move forward along the inclined passage.

Finally, Lin Hao arrived at the end of the passage, and a fiery red light appeared in his sight.

But deep at the end, there was a huge stone door.

Judging from the huge hole, it was obviously forcibly broken open by the previous group of undead warriors.

And the sound just now also came from here.

Walking into the broken gate, what comes into view is an extremely vast underground space.

The environment inside was not as dark as imagined, but a dazzling red, surrounded by rugged rocks.

However, those strange rocks are not ordinary stones.

The entire body was crystal red, emitting scorching fire energy fluctuations, which illuminated the underground space with a bright red glow.

"Fire crystal source stone?"

After taking a look, Lin Hao took out the Dragon-Devouring Sword. The sword light swept past, and a piece of red crystal was immediately cut off.

Holding it in his hand, Lin Hao's spiritual consciousness moved, and the fire energy within it was instantly absorbed by the 'Poison Fire Needle'.

The fire crystal source stone also turned into a pile of powder in an instant.

“The purity is good.”

Lin Hao nodded secretly. There were so many fire crystal source stones in the underground space, enough for the fire poison needles to have a full meal.

"This place is like a maze. The treasures in the core area won't be found so quickly."

Lin Hao looked around and saw that the rugged crystal stones around him formed various cliffs and divided into countless passages.

It looks like an underground maze.

Moreover, these fire crystals seem to have a barrier effect. The spiritual consciousness cannot spread deep into the investigation at all, and all routes can only be explored with the naked eye.

In this situation, it is not so easy to find the treasure without a map.

But for Lin Hao, it was a different story.

Afterwards, Lin Hao summoned the fire spirit and walked along the route on the map, while letting the poisonous fire needles absorb the fire source crystals along the way.

Under its absorption, the light on the route Lin Hao passed was gradually becoming dim at a speed visible to the naked eye.

The underground space is so vast that it seems to cover the entire mountain range.

Even after walking like this for more than half an hour, they had only walked a small half of the distance on the map.

However, the gains from the Flame Poison Fire Needle were quite great.

The speed at which it absorbed was getting faster and faster, and it had even caught up with Lin Hao's pace.

And its energy form is becoming more and more solid, filled with a heart-pounding fire power.

Once such a powerful wave breaks out, it will probably be no less powerful than a volcanic eruption, with terrifying power!

At this time, in various places in the underground maze, the Undead warriors were wandering around like headless flies.

There was no map to refer to, and it was impossible to use mental power to explore the way.

In this situation, let alone finding the treasure, it would be extremely difficult to return along the same route.

"If this continues, we'll all be stuck here."

The leading Undead warrior frowned slightly and said in a low voice: "We must think of a better way."

The subordinates around him remained silent, as they had no better plan for the time being.

They originally thought that as long as the entrance was opened, even without a map for reference, they would be able to quickly search for the core area of ​​the treasure with their powerful mental power.

But now, it is completely beyond their control!

"A bunch of gluttons!"

Seeing that his subordinates had no opinion, the leading Undead warrior couldn't help but curse in annoyance.

If I had known this, I should have found the missing piece of the treasure map earlier.

"Keep looking!"

Faced with a dilemma at this time, he began to get a little impatient.
