Demon Beasts I
While the women were preparing for the banquet, Ling Yun and Zhang Bing worked on installing the cables, lights, and other equipment.
Ling Yun had asked Huang Tian to buy dozens of solar panels for lighting and powering other equipment. Apart from that, he also asked him to buy some generators for backup, just in case the electricity from the solar panels couldn't meet their needs.
Ling Xi also helped them speed up their work, for only the three understood everything.
Ling Yun purposely installed those solar panels relatively high from the ground, for their residence was surrounded by dense forest, so there were too many tall and large trees to block the light.
