Thanks to the renowned biotechnology of Zeta, they were endowed with sweat glands comparable to humans, otherwise, they wouldn't be able to handle such high-intensity physical labor.
Under the players' command, they were divided into four teams.
One team carried sleepers, one team carried rails, one team nailed the tracks, and one team tamped the ballast. Marching across the plains, they resembled a slowly yet steadily operating machine.
The construction materials were on the train behind them, and it was also the Lizardmen who were responsible for unloading the rails and wooden sleepers, then pushing them to the construction site ahead with carts.
The railway laying speed was not fast.
Without the reinforcement of the undead, progressing three kilometers a day was already a miracle. Even if some impatient players spontaneously used magic to assist in the construction, it would probably take half a year to extend the railway to the over 200 kilometers away Glanston Castle.
