Gu Can would report to court every day and then tinker in the small courtyard. Occasionally, servants from the Gu Mansion would come carrying boxes to deliver something.
A month passed in a flash, and Gu Can hadn't made any progress. The Minister of State had to file a complaint with the Emperor.
"Gu Can, is it true?" the emperor asked directly.
"Your Majesty, I have a memorial to make." Gu Can pulled it out of his sleeve. A young eunuch came over and presented it to the emperor. After reading it, the emperor was overjoyed.
"Are you serious about what you said?" the emperor asked happily.
"It's in the Ministry of Works courtyard. The Emperor can send someone to check it out at any time."
"Oh, in that case, everyone, please follow me and see what kind of gift our Minister Gu has prepared." Since the emperor said so, the civil and military officials naturally had no choice but to follow.
When Gu Can opened the door to the courtyard, the smooth cement floor caught everyone's eye. When they walked in and saw the transparent glass on the window, they couldn't help but gasp.
"Is this transparent glass? It's actually used to install windows. Minister Gu is too extravagant." Wan Huan, the Left Vice Minister of the Ministry of Revenue, is the prince's man.

Colored glass is fragile, and a piece this large would cost at least five hundred taels."
"Hahahaha, my dear, just tell them how much this glass costs." The emperor was very satisfied after seeing it, and he was in an even better mood after hearing these people's speculations.
Apart from anything else, the royal family of Qi State loved colored glass very much, and everyone in Qi State followed suit. However, they had never had such transparent colored glass, let alone one that was so luxurious as to be able to use it as windows.
This technology alone can fill the national treasury.
"This piece of glass costs five hundred coins."
"What? How is this possible? Five hundred coins for such a big piece, and it's transparent. How is it possible for it to be this hard and translucent?" The Minister of Works immediately rushed forward and examined it carefully.
