The bone blacksmith respectfully knelt on one knee and offered his loyalty to the Demon King, and then fell into a daze when he heard this.

"The young man's soul fire is quite big, a little bigger than the Headless Horseman," Nishizawa sighed with his fingers tapping the armrest of the throne, "It's just that his brain is not very good." ”

"You see, I have talked about the blacksmith profession so highly, you don't even understand. The Demon King shook his head, distressed that no one responded to his jokes.

Nishizawa decided to give him a qualification fruit.

It is estimated that this bone blacksmith will be like the bone mage, and after eating too much, he can remember a few casting secret recipes or something.

It just so happened that I had fused many times just now, and I had saved up enough for 100 fusion coins.

Nishizawa buys a qualification fruit at the shop and hands it to the bone blacksmith.

Rub Rub Woo ——!

The latter's soul fire skyrocketed at a speed visible to the naked eye.

The qualifications of the Bone Blacksmith have successfully reached the elite level.

At the same time, Celia returned to the throne with a team of skeletons.

The Dark Princess blinked and waved a gray mist at her hand.

At first, Nishizawa thought she was going to do it to herself.

But soon it was seen that the fog had formed a light curtain.

Then he saw a scene on the light curtain.

It was outside the Great Tomb, and there was an iron mine.

The mineral deposits are not large, but they are enough to arm the high-level undead under Nishizawa's command.

However, inside the cave, there are many wild skeletons roaming, and among them there are several headless horsemen, all of which are well-armed.

Look at the poor headless horseman next to me.

Nishizawa even wanted to torture the soul of his headless horseman, why didn't you wear a few more pieces of equipment when you died?

"You guys, come with me. Nishizawa left the bone blacksmith in the Great Tomb, and the other undead leaders with him.

Especially Celia, who is a super thug!

The power of the Great Tomb, except for the weakest white bone beast, almost poured out.

In the first battle since the crossing, we must play with momentum and level.

Soon, Nishizawa led the undead to the outside of the iron mine.

The large mineral deposits around have been dug up by the big graves, and only these small mines are not looked down upon by his dead ghost father, so they have been left until now.

Nishizawa muttered that mosquito meat is also meat, and craned his neck to look inside.

"My plan is this, the first step, quietly approaching. ”

"In the second step, the Headless Horseman leads the Skeleton Warrior to charge in front, while the Bone Spearman and the Bone Mage lead the Skeleton Archer to cover the fire in the back. ”

"The other undead leaders formed a reserve and waited for an opportunity to attack. ”

Nishizawa nodded, "It's me, it's really a seamless plan." ”

Celia also nodded earnestly, and it could be seen that she admired the Supreme Master's plan very much.

Then a wild skeleton wandered around and swayed to the door of the iron mine.

Its hollow eye sockets cast a confused look.

Then, he resolutely launched a charge towards the Demon King Corps, which was dozens of times his size.

Like a fly, the Headless Horseman slashes wild skeletons into slag with a single sword.

But the latter's skull, like a football, slammed into the rock wall of the iron ore field, making an extremely crisp sound, and then shattered with a clatter.

In the entire iron ore field, because of this sound, the wild skeletons wandering everywhere all cast their eyes faintly to the door.

Plan the first step, fail!

Nishizawa, "......"

The Headless Horseman scratched his head.

Celia also has a cute crooked head.

Nishizawa seemed to see a question mark appear above her head.

"Don't plan it, just give me a flat push. The soul fire in Nishizawa's eyes was expressionless.

The Headless Horsemann was the first to rush out.

The skeleton of the white skeleton under his command is tall and powerful, and it only takes a single collision to smash a stunned skeleton into slag.

Then he swung his rusty sword and slashed down, instantly slicing a zombie into pieces and shattering its limbs.

The Headless Horseman instinctively roared silently, and the two low-level undead who were killed by him, soul fire emanated from their shattered bodies, all of which were absorbed by the soul fire in the headless horseman's eye sockets.

In Nishizawa's line of sight, the text above the Headless Horseman's head immediately changed.

His level has risen from Boss Level 1 to Boss Level 2.

"It turns out that the undead are normally upgraded this way. Nishizawa rubbed his mandible and nodded slightly.

Not to be outdone, the bone mage swung his bone staff twice in a row, and the light of stone skin and madness shone on his body.

He took the lead, and when he went down with a staff, he was a small skeleton.

The skeleton archers did the same, rushing to the wild skeletons and firing their bows and arrows into their eye sockets.

Nishizawa lifted his forehead and sighed.

These skeleton shooters, whose cognition is like a blank sheet of paper, are completely distorted by the bone mage.

What kind of virtue is your shooter?

Celia, the strongest beside her, is too lazy to do anything, very Buddhist, and has been teasing the white-boned chicken she holds by her side.

The only one in his own family with a normal painting style should be the bone spearman.

Look at this precision, a spear down is directly a string of incense.

Wait a minute...... Paper, young man, why are you using your ribs and thigh bones as spears?!

Nishizawa was even more surprised to find that after killing several wild skeleton wild zombies, the bone spearman was also upgraded.

The way it upgrades is peculiar.

It actually increases the number of ribs and thigh bones!!

Nishizawa sighed.

It's not easy to bring the team.

One undead lord, two undead bosses, plus an undead boss, none of them have a normal painting style.

The skeleton blacksmith sitting in the Great Tomb must be normal!

There was nothing unexpected about the battle, it was crushing from start to finish.

The Demon King's army swept through, the wild undead collapsed at the touch of a button, and the iron mine fell into the hands of the Demon King.

The only thing worth mentioning is that this place should have been occupied by other forces before.

Not only some basic mining facilities were left, but also mountains of iron ore were left.

With a little smelting, soon the first iron-armed regiments will appear in the Great Tomb.

Nishizawa commanded the low-level undead to load the ore into the back basket and carry it on his back.

The Bone Mage, who had taken the lead all the way, turned back at this moment and gestured towards Nishizawa.

"There's something underground?" Nishizawa probably understood what he meant, and wondered.

The Bone Mage nodded, and walked ahead.

With a wave of his hand, Celia and the Headless Horsemann followed closely to act as guards.

When he came to the space under the iron ore field, he was surprised to find that there was a heavy metal gate nearly thirty meters high.

And judging by the surrounding situation, the last force that occupied this mine did not find such a huge underground space.

Later, the wild skeletons who occupied the place inadvertently crashed into the thin earthen wall and discovered the place.

Of course, they don't have the wisdom to know what that means.

"This style doesn't seem to be undead. Nishizawa looked up at the metal gate.

Such a big door, there is not even the slightest pattern on it.

And there are no traces of rounding in the corners of the gate, and there is a cold, resolute and unadorned steel hideous everywhere.

In Nishizawa's superficial understanding of the world...... He didn't know what kind of remnants it was.

"Seal it up first, and explore it later. "Nishizawa wasn't going to die.

Even if there were many treasures in the ruins, he had to obtain enough information to open this metal gate.

If you go in with complete inadequate preparation, it's not a treasure hunt, it's a death hunt.
