Three weeks later;
"Day 20, Experiment no. 36. Subject: Rank-8 Robot."
Mark carefully inserted a 1cm*1cm chip into a cube-shaped core made of titanium alloy.
After successful insertion, he placed it on one of his palms and used the other to pour ether energy into it, giving it the necessary power.
Soon, all the markings that appeared on the core were filled with blue light, making it seem like a burst of energy trying to escape a maze that has no exit, once the notification received by Mark about the completion of this step, he went on inserting it into the chest of a Rank-8 robot, "Alina, switch on the battery."
While the core could be supplied the power through his ether particles as its needed energy, the robot, on the other hand, needed a battery as the power source as it runs on electricity.
But, creating conventional batteries is a time-consuming task and he doesn't want to stop the production of his weapons, now that they went into the market a week ago, resuming his business.
A store was set up in atleast one city of every state of the alliance and the grand opening happened a week ago.
Things haven't been as smooth as he expected, atleast in some states like Eastern Sun due to Ouyang Zen's dissent to let his public access to the firearms and Qilin Empire, where the Ming dynasty or its people not being able to get used to a new type of weapons that could actually hurt them if they are not careful.
Of course, the Ming Dynasty was quick to act. Within just one week of its release, Emperor Ming passed an order to put an age restriction on firearms and explosives.
Anyways, back to the factory, Mark opted to use electric current-filled scrolls available in the market, each costing up to 3 gold coins and supplying electricity to at least 5 electric fans and 6 bulbs for a whole day. A scroll can also be used to charge the rank-1 robot to full.
It was expensive for normal people but for the rich, it didn't cost much.
Mark didn't hesitate to use 120 of them at the same time, supplying the electricity to the Rank-8 robot, which had its energy depleted completely on purpose.
*Ding! Now that I was integrated with the robot's nanochip, as long as the core is intact, I can establish a connection with every other robot that has a similar nanochip even from a distance. Essentially, apart from the higher quality robot (Rank-10), I could now control every other robot that is 500 meters around my body.
However, I recommend building more cores to give intelligence to every robot here, in order to improve work efficiency.
"Ultron..." Mark's eyes lit up.
Ever since he got a robot from the system, he always had a fascination with commanding robots like how this character named Ultron did it in a movie franchise, back in his past life.
However, after using the robotic army, it didn't feel like it. Instead, he felt more like a necromancer who is using an undead. But, with added intelligence to the robot, where its main consciousness lies inside him, he felt like his dream could be achieved.
While there was also a worry of losing control over the artificial intelligence that keeps on learning new things, he was confident in destroying them too, with his newfound strength. But, it isn't also the time to think about unnecessary things. He felt like this was the time to focus on development.
Slightly tweaking his intended plans, Mark then spoke to the robot, "Your name will be Ark Prime from now onwards. I give you permission to name the robots you will give intelligence to."
"I understood, Master," The robot placed his arm to its chest and bowed its head slightly.
Mark continued, "Your first task is to give intelligence core to all the robots here."
"Understood, master," The robot nodded, but then it replied immediately, "However, I recommend Master to do this task."
"Me? Why?" Mark was taken aback by its request. It's Day 1 of its creation and it is already disobeying his orders?
The robot clarified by explaining, "When the Master creates the core, the master's ether energy is being integrated with the core, and I could extract a basic or a variant attribute from it, giving its properties to the robot. This body has inherited the element of space." Following its words, the robot created a set of black portals, one before it and the other ten meters away.
It walked into it before walking out from the other.
"The f**k... you can do that?"
