"HSS..."
"Good lord. The iron boiler and the high-efficiency boiler make sense, but this alchemy furnace..."
"It's just ridiculous!"
Su Mo felt a bit tempted when he first saw the iron boiler's upgrade path.
In his understanding, iron was much simpler than rammed earth in terms of safety, thermal conductivity, and even maintenance.
The high-efficiency boiler was even better. It could drastically boost attributes on the original foundation, ensuring higher thermal conversion efficiency and easier future maintenance.
But Su Mo had to admit that the moment he saw the words "alchemy furnace," he changed his mind three times within a mere five seconds.
Since the ancient historical records of Huaxia, the alchemy furnace had played an indispensable role.
It cast a shadow in the biographies of every emperor, and it was an absolute necessity in the myths of gods and Cultivation.
