Initially, the Qi Refining Disciples from both factions didn't pay much attention to laying the foundation, so Gazi and the Little Celestial Master had to repeatedly emphasize that this was the most crucial part and explain the potential troubles that could arise from sinking foundations.
After all, Cultivators have a broader vision than ordinary people, and after two days of work, everyone figured out the construction model.
Ultimately, it's mainly about using strength to smash out the foundation, then using Storage Bags to sprinkle a line of gravel to stack it up, while the remaining tasks of laying railway sleepers and twisting rails are left to the Mortals.
After another two days, the disciples from both factions surprisingly figured out a way to collaborate; since the two railways were not far apart, they could handle the foundation laying together, each taking responsibility for a section.
