Chapter 147

Golden Lucky no longer held anything back. He took out a bronze disk with a needle set upon it, a tiny hole at each end.

"Astrolabe?" Rong Xi blurted out.

In his previous world, the Astrolabe had been used in ancient foreign lands to measure the angles of celestial bodies, hence the name "Astrolabe."

Those celestial bodies included the sun, moon, and stars.

Golden Lucky was immensely surprised. "Eldest Brother recognizes this?"

After making money selling fish, he had hired craftsmen to make the Astrolabe. As far as he knew, no one in Great Wei understood its purpose.

"I once heard of it from traveling merchants," Rong Xi replied calmly.

The Astrolabe could measure time, latitude and longitude, and more. It was indeed rather advanced, yet it still had its drawbacks.

Golden Lucky glanced at him. This fool actually had the same thought
