Sixteen years passed from that first order, around the ship nine new towers were being built, the starting 20 sinths soon increased up to 2500, and the number was still growing, the first generation of sinths had already died out.
The nine towers had a precise job and it was drawing near the day they had to do it, they were already around two third finished.
Since Raphael didn't had to add anything else on the towers he started working on the security of the zone.
Even if every animal died and there was literally no danger that wasn't going to continue once the second phase started.
Raphael descended in the lower floors, un floor deeper than the sinth's room there was a robot maker, a machine that could be used to create robotic being fused with some organic matter.
Even if way stronger and faster than the sinths the robots didn't had a real initiative and didn't really think at all, they simply followed orde, nothing less nothing more, the reason the Alliance used the sinths was also because they couldn't be hacked, but now that was no longer a problem.
Time flew and 5 years passed in a flash, the towers were built and ready for their activation.
Raphael's body was afloat in the cryogenic capsule, a frozen transparent liquid was enveloping him, it began to heat and melt, as it returned to its liquid form it got drained slowly in a pocket at the edge of the vat.
Raphael's body laid naked on the cold floor of the capsule, his body gradually heated and slowly his pulse returned, confused he got up and the glass tube instantly slided up letting him free.
He hated the cryogenic capsule (a stupid, but useful invention of that damned slug), but he also knew that staying too long active would bring a deterioration to his cells, because he was one of the "humans" with the most mutated genetics, even if it didn't seem, he needed a great deal of energy, and for that energy he needed meat, something he lacked at the moment, his body without sustainence would begin to eat itself alive.
He slowly walked towards the windows and he saw a view that amazed him, the towers were working each of them active was giving of a faint different color.
He stood a few moment lost in the view before a sinths named Tand03, the youngest of her generation, she with a cold voice said "Master the towers are completed, we followed every order perfectly, what is our next job" a strange hint of fear could be heard in her voice.
Raphael without looking at her started laughting adding "I see, I will be in front of the first tower in twenty minutes, be ready there with 20 sinths, this is the beggining of the second phase, a smile appeared on his face, a smile so big and unnatural that for a moment even the cold Tand03 felt a subtle fear.
