As Ethan ventured further into the heart of the city, he encountered little resistance. With the defeat of the pilot, the once-mighty army of robots had lost their directive, left without a leader to guide their actions. They stood dormant, their mechanical bodies motionless and inert. It seemed that without the pilot's command, they had become little more than lifeless husks, no longer a threat to Ethan or anyone else.
Undeterred, Ethan pressed forward, his determination unwavering. He scaled the towering walls that guarded the center of the city, his body fueled by a mix of adrenaline and purpose. As he reached the summit, he beheld a sight that filled him with awe and apprehension. This colossal, elongated structure was many times bigger than stadiums, stretching far into the distance like a technological spine. This was the very heart of the city, the pulsating core that supplied it with the life-giving energy.
