The days go by.

And the resources that Grim had hoarded during this time were also disappearing from the shelf, and then little by little they were transformed into the strength he had.

Following the two wizard-level golems, the heart core of the Tier 2 Molten Core Giant was also successfully transformed into a terrifying elemental golem by Grim, the Flame Tyrant.

Of course, limited to Grim's own ability, this Flame Tyrant would definitely not reach the level of a second-order wizard, but the power of earth and fire inspired by his gestures also had the terrifying ability to crush a first-order wizard.

After the detailed inspection of the Grim chip, the Flame Tyrant's normal attack can also reach a terrifying strength of 110 degrees, second only to Grim's strongest single attack sorcery. And the two types of witchcraft inspired by the Flame Tyrant have an attack strength of up to 191 degrees.

This...... This is almost the lower attack limit of a Tier 2 wizard!

In the wizard group, most of the witchcraft defense of ordinary Tier 1 official wizards is between 90 and 130 degrees. This also means that once the strongest sorcery activated by the Flame Tyrant is not dodged or negated, he already has the power to kill ordinary wizards in seconds.

With the birth of the Flame Tyrant, Grim's chagrin after losing the Flame Lord was swept away, his waist was straight again, and the whole person was full of confidence in the Sky City.

…………

Inside the Wizard's Tower Residence.

Grim's room has undergone a radical makeover, and it is no longer what it used to be, but more like an operating room.

All the furnishings were cleaned out, leaving only a clean and tidy stone platform in the middle of the room. Dozens of intricate and delicate robotic arms are suspended above the stone platform, and at the end of each arm can be seen surgical instruments of completely different styles and purposes.

Scalpels, surgical scissors, vascular forceps, surgical forceps, needle forceps, tissue forceps, sponge forceps, right-angle forceps, round needles, triangular needles, rongeurs, etc......

Knives, hammers, drills, chisels, needles, saws, and other tools of all kinds, all of which Grim borrowed from the wizard of Kogan. And their original purpose was to transform witchcraft beasts......

Today, as the big day of transplanting the heart of the firedemon, Grim called Alice early and asked her to lead a group of apprentices to guard the door for him. He hid in his own home and completed the arduous and complex organ transplant alone.

In order to avoid outsiders from doing anything to prevent this process from being manipulated, Grim did not use the wizarding lab's chamber in the Wizarding Tower, nor did he ask for the help of Wizard Kogan. Even the reason for summoning the apprentices was a dangerous sorcery experiment, without revealing the heart of the Flame Demon to the outside world.

After staying in the wizarding world for so long, being cautious is the only way for Grim to protect himself.

In this strange world, the only person he can trust in part is Mary. As for Alice and Kirby, it will depend on their future performance and attitude.

After a sweet night's sleep, when the alarm sounded in his head, Grim woke up from his deep sleep and slowly opened his eyes.

This sleep was very sound, and it was more relaxed than ever.

Without dreaming or meditating, Grim let go of all his heavy sleeps and completely recovered from the tiredness and fatigue of these days.

Stretching and sitting up from the bed, Grim stood in front of the bed and moved briefly until the chip had completed the self-examination of his body.

"Drop, the body self-test is complete. The data are normal, and the ontology has reached the best state at present......"

Grim nodded in satisfaction and looked down at his tall, toned body.

Grim wasn't a body sorcerer, so he didn't have those perverted muscle blocks that were as hard as iron. But with a height of up to 2 meters, his well-proportioned and toned body still gives him a near-perfect body. Strong muscles, dark red and shiny skin, and weird tattoos all over the back of the chest.

With his long dark red hair scattered behind him, almost waist-high, and with the dark red light in his black pupils, Grim's whole person exuded a hint of evil, mysterious, and wise wizard flavor.

No way, since completing the elementalization of the Body of Flames, dark red has become his standard. This is also the sorcery luster that is transmitted after the convergence of massive fire elements, which can no longer be covered with ordinary camouflage techniques.

Although there was no dirt on his body, Grim still habitually came to a fire bath.

The sudden rise of elemental flames erupted from every pore on his body, forming a bright red film of flame on the surface of his body, and all the dirt on his body would be completely incinerated by this layer of flames, leaving no trace behind.

As for the ordinary nightgown without witchcraft protection, it turned to ashes in an instant and disappeared without a trace.

Grim didn't wear any more clothes, and walked out of the bedroom naked and went straight to the operating room, which had been converted from a workshop.

Grim closed his eyes again and checked the sorcery protection of the dwelling, making sure that all the sorcery protection was turned on, and that it was protected without leakage.

He lay peacefully on the cold stone platform.

On one side of the stone platform was a metal headband resembling a hood, which Grim silently wore on his head.

When his spiritual power penetrated the metal headband, dozens of mechanical arms suspended above the stone platform were immediately activated and began to squeak and move.

Grim snapped his fingers, and five high-definition flame mirrors emerged from all angles above the stone platform. Through them, Grim could see the area he was about to operate on from almost all angles.

The fluorescent glow on the surrounding walls gradually dissipated, plunging the surrounding area into darkness. More than a dozen illumination crystals cast a bright and soft light, which reflected the subtlety of the surroundings of the operating table.

At this moment, Grim's expression was strangely calm.

"Chip, let's get started!"

With this order, the chip immediately took over all the surgical magic weapons.

There was a flash of cold light in the air, and a magic arm floated to the position of Grim's chest, and the sharp scalpel at the tip of the instrument plunged into his chest, stabbing through the flesh with a thud.

The urgency of its momentum and the accuracy of its movements are simply amazing!

If it were replaced by Grim to control, he would never have been so resolute and decisive.

I don't know if it was because Grim's physique was special, or if the scalpel's cutting did not damage any large blood vessels, so there was no blood splashing in the sky. And with Grim's current physique of 3.7, even if he doesn't rely on any witchcraft, his skin and flesh are tough enough to fight with the Iron Armored Rhinoceros.

Therefore, it is a little difficult to cut through Grim's skin by changing to an ordinary mortal weapon. And the magic weapons used for surgery today are obviously enchanted!

After completing the chest opening work, the scalpel magic weapon was immediately removed, and two magic weapons with humanoid palms flew to Grim's side, gently ripping open his chest.

As a result, Grim was exposed to a human heart heavily protected by thick sternum and ribs. Although this heart has been somewhat mutated due to its long-term immersion in the dense fire element, its basic form and function are not much different from that of a human heart.

Grim watched calmly and quietly, and did not interfere with the control of the chip.

Although he is the true owner of this body, it is impossible for him to perform meticulous medical surgery with the precision of a chip that is as unrelenting and precise as a blood vessel junction.

As some flywheels and bone-cutting knives flew in, a piercing blast of bone-cutting rang out in Grim's chest. Without the Enchanted Sharpness and Solidity, it would have been impossible for these weapons to damage Grim's bones and flesh protected by the power of magic.

The concussion of the metal flywheel cutting the bones, the sharp pain caused by the flesh being torn apart, were all transmitted to Grim's soul. He could only endure it silently, and he had to keep his eyes open and take every detail into his eyes in great detail, so that the chip could be operated and controlled more delicately.

As ribs were amputated one by one, Grim's heart finally burst out.

Then the flywheel and the bone-cutting knife moved away, and more magic weapons rushed up, and began to cut the blood vessels between the heart and the rest of the body in a meticulous and rapid manner. Every time a blood vessel is severed, a tiny burning ray enters and temporarily seals the blood vessel.

And Grim also began to control his body synchronously, tightening the blood vessels throughout the body, slowing down the blood flow, so as to avoid massive bleeding in the chest cavity.

A dark red glow lit up in the darkness.

The heavily treated Heart of Fire Demon slowly floated to the front of the operating table under the support of a tray. A magic arm carefully picked it up and hovered beside its chest, waiting.

Grim's gaze quickly swept over the Heart of Fire, and he saw a dense network of strange runes in the dark red tendons and flesh. These sesame-sized runes filled the inside and outside of the Heart of the Flame Demon, and together they formed a complex and mysterious rune array.

With a sharp pain, the last aorta connecting the heart was severed, and the heart, which was still slowly wriggling, was lifted out by the magic arm.

There was no time to hesitate at all, and the new Fire Demon Heart was immediately stuffed into Grim's chest, and then countless slender magic arms probed into it, using unimaginable witchcraft methods to quickly connect the blood vessels one by one.

The whole process was complicated but not chaotic, with more than a dozen magic arms coming and going, and all kinds of strange sounds were constantly ......

After Grim was promoted to a wizard, his vitality and physique had far surpassed that of ordinary mortals, and coupled with his elemental body, even if his heart was removed, it would not cause him to die directly.

However, this heart-swapping operation still can't last too long, otherwise his body will be affected, thus reducing his basic physique.

To be honest, because of the influence of body elementalization, the body enhancement methods that were suitable for body refining wizards were no longer effective for him. Therefore, once the physique is reduced, it will be extremely difficult to raise it again.

Ever since he learned the savage style of the powerful sweep after the fire demon's transformation, and then let Grim retreat to the soft wandering attack of the elemental wizard, he would find it extremely unbearable!

Therefore, the entire heart exchange operation ended quickly under the extremely precise control of the chip.
