“A barricade…”

“If we have a barricade, we can delay enemy invasion.”

“Probably.”

If a barricade was built throughout the entire border and guards were placed at certain locations, others wouldn’t be able to easily invade Black Scale. However, Zaol couldn’t help but point out the flaw in Lakrak’s idea.

“But it will take a long time to build a barricade this long.”

“How long do you think it’ll take?”

Zaol was in charge of almost everything related to the construction of Orazen. There were better individual architects, but when it came to planning large infrastructure, Zaol was the best.

“If you want the barricade to be worth building, it might have to be as tall as or even taller than Automation’s rampart.”

There hadn’t been any more invasions once Lakrak obtained Automation. The only reason Automation’s barricades had become famous was that in the previous era, there hadn’t been any well-organized armies. Automation’s barricade was five meters tall, but it wouldn't be difficult for an army to scale it with a ladder.

Lakrak nodded in understanding.

“And it isn’t possible to build the barricade with clay like Automation’s rampart. Not only are there more rocks than clay in the valley, but if we did use clay in the wilderness to build the barricade, the water in the clay would freeze in the winter and melt in the summer, making it soft and mushy.”

Clay was everywhere, so it was good material for building short walls, but it wasn't the right material for everything.

“Stones are as common as clay. If we pile up stones first and then support them with clay, we should be able to build a barricade taller than...
