Master hurriedly said, "Magical metals such as Mithril and palladium can only be regarded as second-class, and the Immortal Furnace must use Adamantite Gold and Titanium as the main materials, and the most important thing is a scorching heart. ”

The Bone Blacksmith's soul fire conveyed excitement, "Each Scorched Heart is the most essential flame condensation in the Fire Elemental Sovereign's body, and only it can provide immense and lasting burning power. ”

Nishizawa shook the grass in his heart.

For every time an Immortal Furnace is built, a Fire Elemental Monarch is killed!

Nishizawa coughed dryly and crooked.

The dead ghost father is really awesome, and he can easily overturn the Fire Elemental Monarch.

"Wouldn't it be possible without a scorching heart?" Nishizawa said casually.

Master scratched his head and said, "There seems to be a record in the dwarven inheritance that if you use Mithril and a second-level magma stone, it is estimated that you can also achieve part of the function of the Immortal Furnace, but it can only be regarded as a weakened version. ”

"Moreover, magma stone is a consumable item and will have to be replaced after a while, but the Heart of Scorch will automatically absorb the fire element in the air. ”

Nishizawa nodded slightly, "In the future, let's expand this floor around the old site of the Immortal Furnace." ”

Master immediately nodded, "Obey the orders of the Supreme Lord!"

His heart stirred.

He immediately understood what the Supreme Lord meant.

The Supreme Lord must have planned to build the Immortal Furnace!

The Undead's Immortal Furnace is a super-melting pot that rivals the dwarven Volcanic Furnace of Doom.

If one day he could touch the Immortal Furnace, Master felt that his life would be worth it.

Sure enough, the Supreme Lord is a crucible seeker with great ambitions!

We are like-minded!

Celia's big eyes also sparkled with brilliance.

Wow.

Hey melting pot!

It must be amazing!

Awesome, Supreme!

Nishizawa had no idea what Master and Celia were thinking.

The reason why he had the bone blacksmith build around the site of the Immortal Furnace was built.

It's all because the site is right in the middle of the "Land of Flames and Furnaces".

Build around it, and it's symmetrical.

No way, our obsessive-compulsive disorder is like this.

After pretending to inspect the smelting ore again, Nishizawa went to the sixteenth floor.

The little girl soon lost interest in the boring inspection, she yawned, hugged the white-boned chicken, and said obediently, "Supreme lord, I'd better go back and sort out the books." ”

"Well, there you go. Nishizawa nodded casually.

A place of fighting skills and tempering.

Abbreviated as the Great Arena.

The environment here is similar to that of the Colosseum in ancient Rome.

Surrounded by stands, the ground is hard rock.

Even an attack from the Undead Monarch would not be able to shatter the rocks here.

Only a full blow from the Undead Emperor will cause a crack to appear.

This is the super-hard "Abyssal Rock" that Nishizawa's dead ghost father moved from the Abyss, and it has the same super hardness as the "Hell Rock".

The Grand Arena occupies a huge area.

Now there are only a dozen undead on the field, and it seems to be alone.

When Nishizawa appeared, Oliver was colliding with the Dark Knight.

Without any weapons, just boost your speed to the limit and collide!

After a violent collision, Oliver's horse's head flew far away.

However, the Headless Horsemann didn't care about carrying it back and pressing it to his neck.

That's right.

The Headless Horseman, now a horse-headed horseman.

And his horse, however, lost its head.

In Nishizawa's sight, there was an extra line under the headless horseman's innate ability.

[Temporary Ability: Bone Horse Hurricane.] 】

[Bone Horse Hurricane: The Headless Horseman obtains the head of the Bone Horse under the seat, and the speed is +3.] 】

Nishizawa was a little speechless.

Since you wear this horse head, you have become a ghost fire boy who does not recognize your six relatives.

Why don't you wear a horse's head every day?

"Come again!" Oliver snorted.

I don't know why.

There was a human voice coming from the horse's head, and I always felt a little strange.

The undead onlookers came out in all sorts of ways.

The rotting zombie shoved back the intestines that had come out of its abdomen as it stared intently at the second collision.

The pus zombie helped him pull out his intestines again.

The skeleton spearman tried hard to get on the bone horse, and the latter tried to throw him off.

Bone dogs, bone cats, and bone lizards, you chase me, catch chickens, fly dogs, and jump.

The pale prisoner lowered his cage to rest, and by the way, he removed one of his ribs to replace the broken part of the cage.

The Undead Decapitator wields a head-taking axe and is slashing two angry spirits.

By the way, these two angry spirits are undead leaders, and they were both made by Nishizawa.

Nishizawa smiled with satisfaction.

Look at this lively picture, how harmonious and warm.

Immediately afterward, Oliver's second collision with the Dark Knight also came to an end.

This time, it turned out to be the Dark Knight who flew out upside down.

Oliver looked up and laughed, "The most important thing for a knight is speed, you can't beat me with a horse's head!"

The surrounding undead applauded.

The undead of the boss level defeated an undead leader, which was a rare scene in their barren soul fire memory.

"Bang Bang!"

Nishizawa also appeared in front of the undead with applause.

All the undead hurriedly knelt on one knee and greeted their Demon King.

"Oliver, well done!" Nishizawa did not hesitate to compliment.

Oliver's expression was excited, and he suddenly said, "It's all the credit of the Supreme Lord!"

Nishizawa nodded, and said casually, "Have you noticed anything strange about this layer?" ”

Strange to say, he had also seen the other layers through the vision of other undead, and he could find the formations carved on the ground, walls, or domes.

Only this layer of the Great Arena.

It was as if there was nothing left but the incomparably hard abyssal rock on the ground.

Oliver's heart sank.

He was witty, and immediately reacted, this is the Supreme Lord who is examining them!

The wisdom of the other undead was still slightly low, and among the undead present, only he could already speak.

Therefore, the Supreme Lord must have the heart to test his own eyesight!

Oliver immediately said, "Supreme Lord, I have long discovered the strangeness of the Great Fighting Arena!"

"Tell me about it. Nishizawa nodded.

"Lord Supreme, please look, in the center of the Great Arena, these abyssal rocks are a little different in color," Oliver pointed to the ground, and then to the dozen or so pillars around him, "And on these pillars, there is something like a slot. ”

"From what I've observed, it's supposed to be for setting magic crystals. Oliver said seriously.

Nishizawa's heart moved.

He really didn't notice that.

Because the other floors are either floors, walls or domes, they are very conspicuous.

I'm afraid that others won't know that there is the old site of a large formation here.

The young demon king automatically ignored the pillar.

Unexpectedly, it was discovered by Oliver.

"Do you know what this is?" Nishizawa said again, feigning nonchalance.

As their Supreme Lord, they must not show the slightest ignorance.

Oliver was in his heart again.

The Supreme Lord is examining me again!

Oliver immediately said, "I know, this is a summoning formation for summoning creatures from the abyss or hell!"

Then he said confusedly, "When I was a human knight in gold armor, it seems that I was ordered to exterminate a group of cultists, and they had drawn a similar formation, of course, far smaller than this. ”

Nishizawa nodded slightly, and said in an old-fashioned manner, "Oliver, you really didn't disappoint me. ”

Oliver's spirits perked up, he knelt on one knee again, and the horse's mouth opened up and down, and he said in a loud voice, "The last general Oliver is willing to go to the soup for the rest of his life for the Supreme Lord!"

Nishizawa nodded, "In the next battle, I will let you be the vanguard and perform well." ”

Oliver happily plucked the horse's head and jumped two meters high.

Nishizawa was about to go to the fifteenth floor to take a look, but Celia's voice came from beside him.
