Under the command of Ji Chen, the army slowly marched towards the stone mountain.

During this period, the formation remained the same, with the Naga Berserker in the front, the Dragonblood Fishmen and Orc Warriors on the flanks, the Elemental Sea Elves and Fishmen in the center, and explosive and flammable materials such as the Hydro Spider at the rear.

Ji Chen and the heroes were in the center of the formation and in the safest position.

The so-called lookout mountain runs a dead horse.

The stone mountain doesn't look too far, but it's not a short walk at all.

It took three hours to reach the mountain.

On the barren red gravel, some discordant white spots also appeared.

Gaze intently.

Centered on the rocky mountain, a large number of white bones are buried in the gravel, and scattered skeleton monsters walk on the gravel.

Sensing the breath of the creatures, the soul fire in the eyes of many skeleton monsters shook for a while, and instinctively, out of the desire of the creatures, suddenly rushed towards the old cold legs with their teeth and claws.

Converge into a small wave of skull tides.

At first glance, the hideous skeletons and swaying blue flames are a little scary.

But all of them have been through a hundred battles, how can they be afraid of such a posture?

Ji Chen's expression was certain, and he immediately ordered.

"Naga berserkers ready to withstand the onslaught!"

"Dracus ready for the first wave of throws!"

Watch the tide of skeletons climb over the hills and enter the shooting range.

The Dragonblood Fish-Man then threw a handful of tridents, brutally shattering the Skeleton Monsters before dealing secondary damage as they returned.

As soon as they went, most of the skeletons in this wave had already been killed and wounded, and only a few of them rushed to the front of the formation, where they were smashed by the Naga berserker and splashed into the gravel.

Seeing this, Ji Chen ordered to move on.

Stone Mountain seems to be a gathering point of skeletons.

The closer they got, the more wandering skeleton monsters became, and under the summons of some high-level skeleton monsters, they rushed in waves.

The number of birds in each wave grew from a few dozen, to hundreds, and then to hundreds.

But these strongest skeleton monsters, which were only of the second order, naturally couldn't stop their pace.

Bang~

As the last skeleton is smashed, there are no other skeletons around to attack.

But Ji Chen did not let his guard down, and shouted in a deep voice

"All on alert!"

Then looked around for a week.

Now they were at the bottom of a valley, surrounded on three sides by high ground, and the view was very poor.

The rich experience gained from commanding battles for a long time made him dispatch three reconnaissance teams without a moment's hesitation to climb three high ground to check the surrounding situation.

Soon, the news came back from the three reconnaissance teams, and they found a skeleton camp on the north side near the rocky mountain on the high ground.

Ji Chen climbed the high ground and looked towards the stone mountain, and sure enough, he saw a skeleton camp that relied on the mountain and was completely built of white bones.

Outside the camp, thousands of skeletal monsters roamed.

At a glance, the total number is as much as thirty or forty thousand.

"My lord, are we going to attack now?"

"No, let's take a look." Ji Chen shook his head.

After ten minutes of observation.

I also have a bottom on this group of skeleton monsters.

These densely packed skeleton monsters with a radioactive distribution around the camp include ordinary white skeletons, skeleton dogs, skeleton mages, skeleton vultures, black skeletons, etc.

Among them, the most are naturally ordinary white skeletons, accounting for at least seventy percent of the number.

And there are also a lot of backbones such as Black Skeletons, Skeleton Dogs, and Skeleton Mages, accounting for more than 20 percent.

The least number were the skeleton mages, only about three or four hundred were seen.

The principle that legal units are relatively scarce can be used in any race.

Other than that, no new skeleton breeds have been found, and it is unknown if there are none or not.

Ji Chen also found that every once in a while, some brand-new skeleton monsters would come out of the skeleton camp and staggeringly join the sea of skeletons outside the camp.

At this time, the runner next to him said.

"My lord, this camp seems to be the stronghold of the skeletons in this area."

"And every once in a while, new skeletons appear, which means there's a good chance there's a skeleton lair in the camp!"

A skull lair?

Ji Chen frowned, it seemed that he had heard this word for the first time.

When even asked in detail.

The Skull Lair is a special product of the Undead, and is of the same nature as the Class Recruiting Battalion.

As the name suggests, it can produce a variety of skeleton monsters.

However, the difference is that generally speaking, a class recruitment camp can only produce one class, but a skeleton lair can produce multiple skeletons, which is considered an upgraded and enhanced version of the class recruitment camp.

Listening to it, he suddenly remembered.

As long as you can get one, you will get several different skeleton classes.

Then this thing seems to be quite sought-after among undead players, right?

After thinking about it, Ji Chen opened the forum and entered the keyword 'skull nest' to query.

clicked directly into the most popular post.

"The Skull Lair is an undead system, especially for players who focus on the skeleton system, it is a thing comparable to a legendary treasure!"

"A low-level skeleton lair can produce most of the ordinary skeleton classes of the 1~3 rank, the intermediate one can produce the 2~4 rank, and the high-level one is the 3~5 rank, and the yield is much higher than the general recruitment battalion!"

"If you encounter it, you must take it away by any means! As long as you can get one, undead players will be able to take off in no time! ”

"We all know the truth, but where should we find it?"

"According to the known news, there are only a few dozen undead players who have obtained the skeleton lair, and most of them are still low-level, and the one who got the intermediate skeleton lair has now become the super boss of the undead department."

"If anyone is willing to sell it, I am willing to buy it with all my possessions!"

After more than ten minutes, Ji Chen turned off the forum with a subtle expression.

Unexpectedly, the skeleton lair was such a rare existence in the Overworld.

Among so many players, there are only a few dozen, which is a staggering ratio.

But they had only entered this skeleton secret realm for half a day, and they suspected that they had encountered one.

It seems that this time I came right, the secret realm is indeed a treasure trove.

If you can explore the whole secret realm, you may be able to encounter more!

Looking at the skeleton camp in the distance, his eyes gradually became hot, as if he was looking at a mountain of gold, and waved his big hand.

"All march! Attack the Skeleton Camp! ”

The army marched again, ascended to the high ground, bypassed Ji Chen in two from the middle, and then merged into one, and headed towards the skeleton camp with great vigour.

In the middle of the camp, a tent made up of countless white bones.

Several superior skeletons sit on bone chairs, communicating with their souls.

"How's the production of the Skull Lair?"

"We are already in a stable field, and at this rate, we will soon be able to complete the task given to us by the king."

"The speed is even faster, now that the king's plan to invade other realms is being planned, we must do more for the king's great cause!"

"That's right, the plan of the last invasion was mixed up by a human being, and a general was lost, and the king was furious, so this time the plan can't go wrong again, and it is bound to open the door and completely invade the other world!"

"Hmph, if I meet that human, I'll burn his soul with soul fireballs! Let him live better than die! ”

Just as they were having fun discussing it, they suddenly found that the soul link of several lower-level skeletons was broken.

There was also a strong smell of life outside.

"An enemy is approaching!"

When they received this message, these high-level skeleton monsters were stunned for a moment.

Enemy?

Where are the enemies in the Skeleton Realm?

Could it be that it came in from the outside?

They didn't know what was going on, but a surge of anger surged from the depths of their souls.

For so long, no living creature dared to enter this secret realm, which was also ruled by their skeleton clan.

But today they were knocked on the door, and they suddenly felt that their faces were trampled on.

"No matter what it is, if you dare to attack here, we must let him suffer from soul burning!"

As the fighting drew closer, they took up their arms and walked out of their tents, only to see an army of thousands of men fiercely attacking the perimeter.

At the same time, he also saw the human being commanding in the middle of the army, and suddenly roared angrily.

"Damn! Could that human be the same one who thwarted the King's plan last time!? ”

"Whether it is or not, we must kill him here, or the king will be furious once he finds out!"

"If it is really that human, as long as we kill or capture it and send it to the king, then the king will reward us greatly!"

"Huh?" Ji Chen, who was commanding the army to kill and kill, suddenly found that the skeleton monsters that were originally chaotic began to attack in an organized formation.

Seeing this scene, Ji Chen also reacted quickly.

This is when a skeleton hero begins to command.

He looked around, and soon spotted several special skeleton monsters in the midst of the army of skeletons.

At a glance, it turned out to be all white ordinary-level skeleton heroes!

Is the probability of this secret realm hero appearing so high?

Ji Chen muttered a few times in his heart, and the gesture of command in his hand did not stop.

It's just a few white heroes, and it can't change the situation of the battle at all.

"All assault!"

"Target, enemy skeleton hero!"

At the sound of an order, the army's offensive became more ferocious.

Like a chariot with huge wheels, it crushed towards the skeletons.

Whether it is a white skeleton, a black skeleton, or a skeleton dog, they all turned into pieces of bones before the sharp attack.

Only those three or four hundred skeleton mages could do some damage, but under the volley of elemental sea elves, there were not even bone slags left.

If you look down from the sky, Ji Chen and them are like a sharp cone, piercing deep into the enemy formation.

Several high-level skeletons have evolved to this point, and their wisdom is not much different from that of humans, and when they saw their own skeleton army being broken through like chopping melons and vegetables, the thought of escaping had already appeared in their hearts.

Especially those few enemy heroes who had never made a move, looking at their sharp gaze, made their soul fire almost stop burning.

Extremely dangerous!

"Things have changed! This human and his army are too strong, we should retreat immediately! ”

"Retreat? So what about the skull lair here? And the king will not spare us! ”

Hearing this, the other superior skeletons also hesitated, but one of them quickly found a reason to defend himself.

"It is precisely because this human being is so powerful that we have to report to the king, otherwise it will be even more sinful to let him escape."

"That's right, we're not running away... It's about reporting to the king! ”

Several high-level skeletons instantly reached an agreement, and fled with a small number of elite skeleton monsters.

Seeing this scene, Ji Chen couldn't help but be stunned, and his brows were horizontal.

Want to run? There are no doors!

Immediately said out loud.

"Daro, you're chasing down the fleeing skeleton heroes with the orc warriors! Be sure to leave it behind! ”

"Yes!"

Darrow took the order and went away, leading the half-orc warriors with all the fierce men from the side and chased after him.

Although the skeleton army has a numerical advantage, it loses the command of the skeleton hero and instantly becomes a piece of scattered sand.

Under Ji Chen's command, it was divided into several parts and broken, slowly eating away like a cake.

An hour later.

There was not a single standing skeleton monster in sight, and the mountains were full of broken bones.

"Ding~ You killed thousands of skeleton monsters and increased your level (19→22)."

Looking at the system improvement, Ji Chen's face showed a trace of benefit.

As early as in the previous series of battles, his level reached level 19, and this time he killed such a large wave of skeleton monsters at one time, and the experience he brought brought made him directly upgrade to three levels in a row.

It seems that this trip to the secret realm can allow him to rise to a few levels.

Walking on the white bones everywhere, Ji Chen walked into the skeleton camp slowly.

At this time, a wave of newly baked low-level skeleton monsters swayed from the direction of the stone mountain.

It seems that the skeleton's lair is on the other side of the stone mountain.

With a wave of his hand, Ji Chen asked the army to tear this wave of skeletal monsters apart.

Then he walked towards the stone mountain, and soon followed the traces to a gloomy cave.

Without hesitation, he walked in.

The cave was a little dim, and there were skull torches hanging from the rock walls on both sides that had been artificially rested, emitting a faint blue flame.

Walking down the cave into a few dozen meters, you will come to a circular dome space.

Looking around, a huge skull stood in the center, and a faint blue fire flickered in its hollow eye sockets.

Kara sounded.

The mouth slowly opened, and several skeleton dogs came out of it.

When he saw Ji Chen, he was obviously stunned, and then rushed up.

A few bones shattered sounded, and Anina put down the big sword in her hand and clapped her palms expressionlessly.

Seeing this, Ji Chen also began to look at this so-called skeleton's lair.
