Uchiha Ying Yue and Yuhui Otsutsuki crossed the ruins on the lunar surface together and entered a massive underground passage.
The Moon's surface environment was harsh. The desolate landscape carried almost no trace of life, and just as Yuhui had said, the lunar surface was unfit for habitation.
Ying Yue noticed their footsteps echoing off the hollow rock walls. The air was thick with the smell of dust, and every step seemed to remind them of this land's desolation and cruelty.
Before long, they entered an enormous underground city.
Although the Moon's resources were limited, this complex displayed the Otsutsuki Clan's exceptional engineering capabilities.
The underground environment had been carefully designed, complete with artificially produced oxygen and climate-control systems. There were even basic crop-growing areas. They were far from abundant, but sufficient to sustain the Otsutsuki Clan.
Ying Yue looked around at the buildings, feeling an intense sense of oppression.
Though the place was supported by artificial lighting and air purification systems, it still felt utterly lifeless.
Compared to the prosperity of the Ninja World, the living conditions here seemed exceptionally impoverished.
Although Ying Yue had long been prepared for this, the sight before him still shocked him.
"You must have had a hard time living here, haven't you?" Ying Yue looked at Yuhui, his tone carrying a hint of sympathy.
Yuhui nodded and sighed. "Yes. The Moon's resources are extremely scarce. Our people have relied on these underground structures year-round just to survive, but even so, we often face food shortages and a lack of daily necessities. Though we possess powerful bloodlines and talents, the limitations of our environment have made it difficult for us to prosper no matter what we do."
Ying Yue fell silent for a moment, his gaze sweeping across every corner of the underground city.
