Weapon seller in the world of magic

Fujian Island, Western Moon kingdom;

It was a regular day at the factory. Ark Prime was working on creating a new generation of robots; Ark Secundus was building a supercomputer from scratch; Ark Tertius was working on upgrading Song missile while other artificial intelligence-controlled robots were busy with weapons manufacturing at a rapid pace.

Meanwhile, the factory Guardian, Jingwei, was training with Mark's sister, Shang Jiao.

Both of them have been spending in this factory testing grounds because of its self-repairing feature, and not to mention, it won't attract anyone's attention and let them go all out.

With her icy wings spread widely, Shang Jiao waved her magic staff, turning icy feathers into spikes and attacking her opponent.

Jingwei was moving at high speeds, evading them with ease.

As Shang Jiao continued to attack her, a sudden vibration felt all over the factory, interrupting their battle.

"An attack?" The girls exchanged glances at each other after the second vibration that was generated from the ceiling.

"Let's go out and see."

As both of them rushed out of the testing grounds, Ark Prime spotted them and stopped them, "Wait, it's not safe." He warned.

"What happened?" The Princess asked.

Ark Prime answered, "A domain has been conjured over the region. My connection to the master has been temporarily severed. It should be a demigod, not an opponent either of you can face. But, our defensive barrier has been activated. You would be safe as long as you stay in this facility."

"Not a problem. I can teleport to Papa as we were contracted by blood and soul. It is not something a demigod can disconnect with a domain," said Jingwei. "After returning to his mindscape, I'll inform Papa."

"That seems like a valid approach," Ark Prime, the rank-9 intelligent robot, agreed with her idea.

"Jiao Jiao, I will be back," Jingwei gave a subtle nod to her only friend and closed her eyes, trying to connect to Mark.

She opened her eyes after a few seconds, with a frown on her face, "I can't seem to connect with Papa, either. Why?"

Ark Prime replied, "The domain's power should have exceeded the power of the demigod realm. But, it is not necessary that the enemy is in the immortal realm. Or else, the factory's defenses shouldn't have blocked the attacks. Or, it could have been because the enemy is testing our defenses. For confirmation, we have to go out and scan the domain and the enemy by ourselves."

"So, what now?" Shang Jiao looked at the robot, while a few more AI-powered robots gathered on the spot.

Ark Tertius said, "As long as we can finish the upgrade of the Song-II missile, it will be possible to make a hole through the domain and form a connection with Master. After all, it was designed to tear through space in the first place. Hence, it can do the same with the domain too."

"How long do you need?" Asked Shang Jiao. She has yet to get used to this complex stuff about firearms and missiles or whatever new terms they are, but at the very least, she had confidence in these robots.

Ark Tertius' eyes glowed for a second and it replied, "Estimated time to finish, based on the current pace of development: 41 days."

"41 days?" The ladies let out a gasp.

Ark Prime then said, "It can be reduced to less than 10 Hours with the assistance from Lady Shang Jiao."

"Me?" Shang Jiao's eyes widened and she pointed at herself in surprise. "How?"

Ark Prime answered, "The Orb of time. If we maximize its output and keep its range minimum enough to cover the building site, we can slow down the time by 100 times."

"Hmm… but slowing down the time by 100 times, even in such a concentrated area, isn't easy…" Shang Jiao has never accomplished such a feat. She was worried about the enormous strain on her soul.

After thinking deeply, she nodded with a hardened face, "Alright. If this is the only way to survival, let's do it."

Ark Prime then said, "Meanwhile, I, Ark Secundus, and Ark Quartus will try to distract the enemy."

"You three?" Shang Jiao raised her eyebrow, "Even if you are supposedly at rank nine and able to fight a Supreme realm on your own, you are not even a match to me, much less the enemy."

Ark Secundus replied, "That's because the master has prohibited us from using our attribute powers against Young Miss. If we only focus on using attribute powers, we could distract the enemy for a while."

Meanwhile, outside the factory, Xie Tianyu was seen floating in the sky with a deep frown on his face, "damn it. No wonder that prince asked me to take care of this factory instead of taking care of Lu Zhen. Such building in this lower plane of existence would indeed cause an imbalance of power. Or maybe he already anticipated that I would have to fight with Lu Zhen either way. But a new problem has arrived now. If I can't even break through this building's defenses, would I be able to break through Lu Zhen's defenses? Hmm… Let's just go all out."

Pouring a large amount of his ether energy into the amulet hanging around his neck, which further empowered the broadsword in his hand, Xie Tianyu raised it above his head.

Just as he was about to swing it down, suddenly, the gravity in the surroundings increased abruptly. The pressure on his body was so great that Xie Tianyu started falling at a rapid pace.

Once he landed on the ground, he started resisting the 100 times the gravity on his body, making sure to stand upright as three robots exited the factory and went into action almost simultaneously.

"What? Robots?" A blurry memory came to Xie Tianyu, causing a headache.

"Spatial Distortion"

"Lightning Beam"

At once, the space around Xie Tianyu started distorting, crushing him with spatial pressure. For a moment, Xie Tianyu felt an invisible force squeezing his body, pulling away his skin, in all directions.

As he focused on resisting this effect, the robot shot a concentrated beam of lightning through its palms. They pierced his body and made a large hole in the middle of his chest.

Almost instantly, divine energy flew out of his body and recovered his peak stage while a golden aura enveloped his body, nullifying the effects of spatial distortion on his body. The eyes behind the mask also turned golden, with no visible pupils.

Xie Tianyu charged forward at once and swung the sword at Ark Quartus, who was the nearest.

The robot was split into two parts, falling to the ground.
