Weapon seller in the world of magic

Three days later;

At an unnamed island;

"3, 2, 1…"

*Boom*

A missile was shot from the sky, aiming at the Black Tortoise that is suppressed to stay still by the Gravity Dome.

Of course, the effects of the Gravity Dome were also on the missile. But, unlike the beast, the missile didn't slow down but had its speed increased a thousandfold.

The majestic black tortoise couldn't even conjure up its shield and helplessly stared at the missile that fell on it and its siblings.

As the missile struck the island, the antimatter injected into it released into the surroundings, causing a huge explosion, enough to sink down the entire 1 sq. km of the island into the ocean.

As the Holy beast was drowned in the ocean, Mark came out from the divine throne, which was now in the shape of a huge flying ship in the sky with a missile defense system and a missile launcher mounted on top of it.

He stared down at the body of water and raised his hand, "Release."

The Gravity effects in the surroundings became normal and the beasts slowly floated to the air.

"Mas…ter…" The Black tortoise's pitiful call echoed in the surroundings as its head came out of the water, its gaze was on its favorite human who probably met them only ten times so far in the past year, only to push them to death when met again after a long time, "It doesn't work. We Holy beasts need the offering of a d demigod realm's divine or a demonic beast's heart to breakthrough."

Mark put his hands behind his back, exuding the air of a demigod that people describe in the books, as he replied, "That could be one of the ways, but it doesn't mean it is the only way. From my experience, what I learned is that you could make a breakthrough if you touch the death door. So, try to live while I try to kill you. You'll become a demigod realm beast within no time."

"Mas…ter…" As it once again pitifully looked at Mark, the latter stretched his hands toward it and unleashed another skill.

"Attraction"

A large amount of suction force erupted from his palms, pulling the majestic beast to the sky.

"Ahhh…"

The one with an all-seeing eye, who taught many junior deities in its past life, has now ended up under the mercy of Mark. As it reached its master, a box hit on its head and it flew down hundreds of meters once again and crashed into the waters. It fainted right away.

After a while, as it gained consciousness, the Black Tortoise received a few more rounds of beating to the point of losing its consciousness once again.

Until the evening, this repeated 18 times to be exact but it never showed hostility even on one occasion, despite the fact that Mark never activated his titles of either "Absolute Authority" or "Master of Holy Beasts", both of which give him complete control over them.

Once the sun had set down and the Black Tortoise woke up for the 19th time, expecting to be beaten down once again, it found itself levitating, being carried away into the facility it was familiar with but never stepped inside.

When it entered, the Black Tortoise found its three siblings being tied up on the ground with normal ropes; two of them seemed to be unconscious while the Azure Dragon was struggling to move, flapping its legs and arms uncontrollably but still couldn't break the ordinary-looking ropes for some reason.

Meanwhile, a few high-ranking robots are using various divine weapons (Mythril-grade swords and spears) given by Mark to tear the dragon scales apart.

"Relax, Qing Long, it is just going to be fine. Bear with the pain and you will achieve the breakthrough," said Mark as he walked forward at a steady pace.

"Gra…" "Graaa…" "Graaa…" The dragon continued to roar, pleading with him to free it. But, Mark turned a deaf ear to it and went past it, placing the tortoise on the floor before the robots rushed forward and tied it up with large and thick ropes, which were tied to a heavy steel bar on the side.

Once it was tied up, Mark then placed his arm on one of the ropes that tied its shell and the body.

"Density Manipulation, 1000 times."

Each of the rope and the steel bar had its density increased by 1000 times and the holy beasts' cultivation was brutally suppressed by the factory. However, Xuan Wu has incredible physical strength, especially its hard shell that could even take the attack of an immortal. So, Mark wasn't confident.

Fortunately, his beatings made it completely obedient to the point that Mark wondered whether he should have done the same thing to the Azure Dragon too.

As it lay there lifelessly as if it was implying that it didn't care anymore, Mark observed its shell and knocked on it a few times, speaking out loud, "Ark Prime, does it only work if it was implanted in the chest? Can we implant it in its head, you know, integrating it with its brain instead of the heart? Its shell is a lot sturdier than those scales of Qing long."

The robot supervising the vitals of the dragon replied, "It can be possible, Master, but it will be a complicated surgery. Any mistake will cause permanent damage to the brain, ending up brain dead and living as a nonliving thing for eternity. It is not easy to revive the brain, unlike the heart. Moreover, there is a moderate risk of amnesia and a high risk of losing intelligence.

You will turn a Sage into a fool."

The Black Tortoise didn't know what they were planning but the robot's words caused a shiver all over its body, "ma… master, I… I can remove the shell." It forced out its words in a shaking voice.

It doesn't fear death but fears losing of its extensive knowledge of the cosmos, which it was proud of. Moreover, since it always retains the abilities and the memories it had in past life, Xuan Wu will not retain its knowledge if it loses now.

"You can remove the shell?" Mark always thought that the shell was a part of a tortoise. So, he never considered such a possibility.

"Yes, I… I can transform it into a huge dome to protect the area, but I cannot use it with the suppression on me."

"Hmm…"

Mark thought for a bit and gave a nod, "Fine, we'll do your operation, outside the facility. Ark Secundus, you follow me." "Yes, Sir."

Azure Dragon's eyes widened when it heard him and it tried to protest, "No... this is unfa… Argh…"

Little did it know that outside the facility, as Black Tortoise removed its shield and transformed into a giant barrier that covered its 500-meter surroundings, the Gravitational force descended upon its thin and weak body, almost crushing its bones before it turned upside down and had its interior skin cut by a laser beam by a robot.

This robot is called Ark Secundus, the second robot where the A.I. core was installed, but with inheriting the Gravity powers from him.

Using its elemental and Ark's connection with Mark, this robot managed to stay unaffected by the Gravity Dome and calmly operated on the vulnerable Black Tortoise, which had even louder screams than the dragon.

But, its resistance is a bare minimum and so was its defense. Hence, it didn't take long for the robot to finish its surgery, successfully implanting the A.I. core into the body of Xuan Wu.

Once the operation in finished, Mark removed the gravity dome and resummoned the divine throne from his inventory, using its ability of Divine Healing to heal its external wound from the surgery and the internal injuries from the Gravity Dome altogether.

*Ding! Integration has been successful. Proceeding to dismiss the skill.

Xuan Wu, for the first time, heard a voice in its head that it didn't recognize, but it didn't feel hostile toward it. The beast doesn't know why but it just trusted the voice on its intuition and let it control its body.

Probably the main reason is that Ark's main body and Mark were connected while Mark and Xuan Wu are connected by contract.

The Black Tortoise's appearance was restored and eventually, it has also gone into a deep state of sleep as the rest of them.

Seeing that everything went smoothly, Mark let out a sigh of relief as he stared at the beast, "Beating it to the death over and over made it less stubborn and become more obedient. I thought it would be the hardest to handle because of its arrogance over its knowledge and stubbornness over its decision, but it looks like beasts are certainly different.

According to the glossary left behind by the system, my Primeval bloodline did have an enormous effect on lower bloodlines. Only Primordials could resist it.

Anyway, the first step is done. Now, once the dragon is also operated, I can move on to the next step, Neural Synchronization, and a forceful breakthrough."
