Hierro is the god of wisdom.

Although he is not a great deity, he holds the secrets of the gods.

Therefore, the Wisdom Sacred Scripture he created with his own hands is undoubtedly a great artifact.

After being bewitched and infected by the Sacred Book of Wisdom, Grim had to fall into deep meditation to get rid of those strange powers. Although the process in the middle is unusually hard and difficult, it is very worthwhile.

At least, after reading the first chapter of the Wisdom Tome, Grim's mental power increased from 40 to 41. That's his biggest takeaway!

After entering the 4th level, everyone knows the difficulty of improving their mental power.

Grim experienced a series of bloody battles on the Morian plane, coupled with the stimulation of the divine power aura in the Wisdom Sacred Book this time, which made his spiritual power that he had not moved for a long time increase by 1 point. It is conceivable that in the years to come, this holy book of wisdom will bring him a very considerable increase in spiritual power.

However, after all, Grim's soul origin has not healed from serious injuries, and too frequent mental burdens are not conducive to recovery.

Therefore, under the planning of the chip, Grim can only watch the wisdom tome once a month. The rest of the time, Grim spends his time collating and refining alternative knowledge from the Arcane Empire.

There is only the initial version of the Floating Ring, which Grim betrayed to the Molten City Lord Everred. Obviously, he didn't want to use such rudimentary knowledge, so the chip was responsible for the continuous optimization of the floating ring technology.

However, compared to the low-level technology of the Floating Ring, what attracted Grim's attention the most in the Arcane Empire's knowledge system was the terrifying Half-Plane Fortress.

The Arcane Empire has transformed multiple half-planes into an impregnable fortress of terror.

Whenever the Arcane Empire needs to invade a certain dimensional world, it is this half-plane fortress that is based on the half-plane and uses the floating fortress as a fire turret at the forefront. To put it mildly, the vast majority of the hundreds of secondary planes that the Arcane Empire dominated or ruled during its heyday were brought down by half-plane fortresses.

However, if Grim wants to replicate the glory of the Arcane Empire, he must comprehensively and deeply study the treasures of the Arcane Empire's knowledge system, such as mana pools, spell pools, and energy cores.

This is an unusually large and complex alternative body of knowledge, and even with the help of chips, it will take an extremely long time for Grimm to transplant them into the sorcery system.

Therefore, he was in a hurry, and Grim could only recuperate from his injuries while quietly waiting for news from all sides.

Half a month later, the first good news came.

The Shadow Steel Magic Weapon in the Alchemy Laboratory has been successfully refined!

After receiving the news, Grim rushed to the alchemy laboratory as soon as possible, where a strange and strangely shaped magic weapon floated in the air, standing quietly with its hands down.

It is a seven-foot-tall strange magical machine, made of a dark metal that absorbs light. The entire body was a lean and withered metal skeleton inside, and a black mist lingered on the outside that was impenetrable to the eye.

The slender upper and lower limbs ended in sharp metal claws, and a black metal skull was hidden in the mist, and the location of the eye sockets revealed two gloomy gazes.

It doesn't walk on the ground like ordinary magic machines, but floats in the air half a foot above the ground, as if it doesn't have any weight, moving silently and lightly.

Grim's body was extremely weak during this time, and he was almost unable to engage in any kind of combat with Tier 4 enemies. Therefore, the arrival of this 4th-order mid-level Shadow Steel Demon Machine just filled the void of Grim's power.

With it, even if Grim's strength is now half weakened, he is confident that he will make any intruder suffer a big loss!

"Shadow Fiend, attack me!" Intending to test the power of the Shadow Steel Weapon, Grim summoned a lava shield from outside his body.

At Grim's command, the Shadow Fiend floated over, and with a single stab, the two sharp metal claws dug a large hole in the 700-degree lava shield.

The fire damage reflected by the lava shield only caused the shadow mist outside the Shadow Demon's body to shake for a moment, and then quietly dissolved.

Although it was only a simulated attack, Grim had already obtained the basic parameters he wanted.

Shadow Fiend's metal claw has a base attack of 400 degrees, but since this is a multi-attack, it can deal terrifying physical damage of 400*6 degrees in an instant with a single attack. If you add in the accompanying Shadow Blaster, the total amount of damage dealt by Shadow Fiend after launching a Shadow Strike is between 2900 and 3200 degrees.

And this is not much different from the furious blow of Grim's heyday!

"Shadow Fiend, hide behind me!" After testing his attack power, Grim wanted to test Shadow Fiend's stealth ability.

After accepting Grim's order, the Shadow Demon teleported behind Grim, and then his huge body squeezed into Grim's back with just a few squeezes.

Grim looked down.

Under the bright and soft light of the alchemy laboratory, his back was compressed into a small area at his feet, and it was hard to imagine that such a huge magic weapon could be hidden in it.

Moreover, as Grim walked back and forth, his back was constantly changing and stretching, but he didn't feel the existence of life and energy inside.

Grim casually condensed a small fireball and threw it on his back, shaking it up, countless fragments of black shadows swaying and shaking in the scorching firelight, but he still couldn't perceive the existence of any alien energy breath.

And when the flames disappeared, the backs regrouped together, seemingly unable to perceive any movement inside.

But when the blue light flashed in Grim's black pupils, with his elemental vision, he still found a small dark shadow in the black back, and it was constantly wandering.

Moreover, as the owner of the Shadow Demon, Grim has a spiritual connection with it, so even without the help of elemental vision, he can vaguely perceive its existence and its approximate location.

Therefore, after testing the Shadow Fiend's concealment ability in many ways, Grim finally nodded with satisfaction.

With the close protection of this Shadow Fiend, he is finally safe again!

…………

Inside the Molten Cavern.

A small dark shadow slowly moved through the dark red cavern.

This is the only path to the Throne of Fire, and the highest concentration of fire creatures and metal artifacts. Therefore, if you want to infiltrate the Flame Throne, you must cross this flame path.

Karin is a young witch with reddish-brown skin, blue eyes, and a devilish figure, dressed in a black dragon's skin soft armor that shows off her beautiful body. And she was now wrapped in a layer of black mist, slowly swimming in the shadows under the metal magic weapons.

Inside the Molten Cavern, metal magic weapons belong to fixed guards, guarding every passage and every cave. The many fire creatures are mobile sentinels, wandering aimlessly in the twisting caverns.

Whenever an alien invader is spotted, all the outposts will be activated instantly, destroying the enemy with the most ferocious firepower.

Karin is only a Tier 3 Dark Witch, but what she wants to break into is the private tower of a Tier 4 Legendary Fire Witch.

At any point in the past, she would not have been so unwise.

However, the strict order from the family headquarters made her unable to push it, so she could only grit her teeth and do this almost impossible and terrible task!

Before she came, she had already investigated the legendary fire witch Grim.

However, the more she investigated, the more detailed the information she had, and the more panicked Karin's heart became.

This is no ordinary Tier 4 new wizard!

His fame, his achievements, are written in the blood of the enemy.

What's even more terrifying is that the family headquarters sent her to infiltrate the other party's witch tower, and what she wanted to investigate and steal turned out to be...... Orb of Shadows. This is the most terrifying and incredible part of Karin!

Shadow Orb ...... Wasn't that the most important Origin Sacred Weapon of their Dark Clan? How could it fall into the hands of a legendary fire witch in the middle of the continent who couldn't be beaten by eight poles?

Could it be that the rulers of the family headquarters are a bunch of shit, and they have lost the Shadow Orb, but they don't even dare to start a dark war?

Angrily scolding the higher-ups who had sent her by name, Karin carefully dodged the roaming fire creatures, choosing metal magic weapons to use as stepping stones for her shadows.

One moment, Karin was lurking at the foot of a metal magic machine in a flame cavern, and the next, she appeared in the shadow of the dome at the end of another passage.

Perhaps it was the faint energy fluctuations that accompanied the shadows that caught the attention of some of the flame creatures, and an extraordinarily tall and mighty Flame Guardian stopped in the passage and began to stare at the flame-shrouded pupils, scanning suspiciously around the passage.

Karin, hiding in the shadows of the dome, immediately tensed, her sexy and charming beautiful eyes narrowed into a crack, and she gathered all her killing intentions, calmly observing and examining the fire guard.

The Flame Guardian is not a powerful flame creature, only a Tier 1 advanced base strength!

Karin, who has a third-order high-level strength, only needs half a finger to kill this Flame Guard. It's just that in such an environment, once you move your whole body, once you power this fire guard, it means that your infiltration has failed.

The thought of the possible punishment for returning to her family after failing her mission made Karin feel distraught, and the aura around her became more and more unstable.

But fortunately, the difference in strength between her and the Flame Guardian was too great, and when she hid herself with all her might, the possibility of the other party discovering her was also incredibly low.

Therefore, after looking around and not finding anything unusual, the Fire Guardian was released from its alert state and continued to wander leisurely and leisurely in this area where the fire elemental was unprecedentedly active.

And Karin couldn't help but let out a sigh of relief and began to continue her journey!
