What is the experience of time-traveling without a system or a golden finger? Modern construction worker Yi Qiong's soul traveled to ancient Wanzai. At the start, he just wanted to lie down and slack off until he could go back, but he found that the tower in the barren mountains south of the city that had collapsed for half a century was actually the civilization tower he had visited since childhood. Since he is back, then build it out! The day the tower was completed, the whole city cheered—turns out that tower in his hometown was really built by him.
