Zhao Yao had just returned from the north when he learned that Lian Daci urgently needed to see him. Without even having a sip of tea, he hurriedly headed to the porcelain factory with Tong Xi.
Lian Daci saw Zhao Yao coming and quickly greeted him. He first bowed to Zhao Yao, then said with a face full of joy, "Your Highness, the concave-convex lens you wanted has been made."
Upon hearing this, Zhao Yao broke into a surprised and delighted smile. "Really?"
Lian Daci said, "I wouldn't dare deceive you, it really has been made."
"Take me in to see it."
Lian Daci took out the completed concave-convex lens and handed it to Zhao Yao.
"Your Highness, take a look; is this the concave-convex lens you wanted?"
After taking it in his hand, Zhao Yao lowered his head and examined it carefully, finding both the convex lens and concave mirror very clear.
"This is the concave-convex lens I wanted."
Lian Daci felt completely relieved hearing Zhao Yao's words.
