A family of three travels through time together, and the golden finger is turned on

"Master Gu, please enlighten me." Master Zhang turned and looked at Gu Can. Regardless of the smooth ground outside, the existence of this piece of glass proved Gu Can's value.

"Please take a look, sir." Gu Can took out a booklet and presented it.

Zhang took it and began to read it carefully. Even the Minister of Revenue squeezed over and Prime Minister Gu also stepped forward. It must be said that the feeling of stealing was really strong.

"It's actually true. If it weren't for the labor and kiln construction, the cost would be even lower." They looked at the material steps of the glass and calculated in their minds that the price Gu Can mentioned was based on the scenario where she bought the land, hired someone to build the kiln and recruited workers.

"Master Gu, your achievement should indeed be reported to higher authorities, otherwise Master Zhang will not be able to handle it." The person who spoke was the Minister of Revenue.

"Without the support of Lord Zhang, how could I, an official, have the right to use this small courtyard to conduct experiments. Lord Zhang is willing to help Can, and Can is naturally very grateful." As he said this, he bowed to Lord Zhang.

"..." Didn't they say that Gu Can was dull and too upright? Who said that?

"It's all for the Great Zhou. Researching technology requires a quiet environment. I hope Minister Gu didn't misunderstand." Lord Zhang was naturally using this as a chance to put aside any previous unpleasantness. After all, he'd only ignored Gu Can for a month; it wasn't like he'd secretly plotted against him.

Gu Can's achievements are also the achievements of the Ministry of Works. Anyway, their Ministry of Works is not under the jurisdiction of the Crown Prince. The Emperor is in his prime, so what does the Crown Prince matter?

"Well, there's still something to look at. A piece of glass isn't a great gift." After the emperor finished speaking, all the civil and military officials wanted to roll their eyes. How could this not be considered a great gift? You have to know that such a thing would bring immense wealth. You are so noble and great, but you look down on it. When the national treasury is out of money, who will be in trouble?

"Your Majesty has already seen the cement. This last piece is inside the house. Your Majesty, please wait a moment." Gu Can said as he was about to push the door open.

"Is this the extremely solid cement you mentioned?" The emperor pointed to the ground outside.

"Yes, this cement is very cheap, and ordinary people can afford it. Houses built with cement are very strong and have greatly improved disaster resistance. They are not susceptible to water or fire."

"Invulnerable to water and fire, Minister Gu's words are a bit too much." Someone immediately expressed disdain.

"Your Majesty will know once he tries it." Gu Can was not annoyed.

The emperor pointed a guard over, and the guard drew his sword and chopped at the ground. Sparks flew, but not even a faint mark was left.

"This, this only means that the cement is hard enough." The man still refused to admit defeat.

"Such a hard object, so cheap to make, is already a treasure. If the people of our Great Zhou could use it to build houses, they could survive the cold winter. If it were truly impervious to water and fire, then using it to build riverbanks would avert countless disasters." Prime Minister Gu was no shrew. He truly was a good official who cared deeply about the people.

"If it's used to build the city wall." Zhang Shangshu also had some thoughts in his mind. Oh my god, what a great achievement this is for their Ministry of Works. At this moment, the old man's eyes changed when he looked at Gu Can.

This is the super treasure of their Ministry of Industry!

Cement and glass, as the three treasures of time travel, were naturally familiar to Gu Can. This wasn't her first time making cement in ancient times, and she had refined the formula countless times. To be frank, cement with this formula would definitely last more than three hundred years!

"It's impervious to water and fire, it must be true. This small pool is built with this cement. Your Majesty, all the gentlemen can come and take a look." Zhang Shu and Lin Jinshi also came along. Since they were not high-ranking officials, they naturally stood further away. They happened to arrive at the edge of the pool.

The emperor took the lead and walked over. It was indeed made of cement. The water was clear, and the red carps in it were plump and swimming very flexibly. Just after the emperor walked over, one of the small carps suddenly jumped up, sprayed a water arrow in the air, and then fell down, splashing beautiful water.

"The fish has jumped over the dragon gate. This little fish is really lucky. Minister Gu, can you please give it up? I like this little fish very much." The emperor said in a good mood as he looked at the fish which was so smart.

"That is the blessing of this little fish." This is not a special carp, she just fed it casually and she didn't feel reluctant to let it go.

Jiusheng, the emperor's chief steward, immediately ordered his men to scoop up the fish. Gu Can whispered a few words to Wu Zhubu, who then led his men into the room and brought out a one-meter-square glass fish tank.

"Thank you, Minister Gu, on my behalf." Jiusheng's eyes lit up when he saw the fish tank. The landscaping inside the fish tank was exactly the same as that of a pond, except that it was shrunk ten times. However, it was more than enough to hold these small carps. The transparent fish tank was filled with water, and the small fish were put in. It looked extremely beautiful.

"This is also made of glass. This is too, too luxurious!" This person didn't know whether he was jealous or angry. His eyes were red and he stuck to the fish tank, not willing to leave for a second.

"Master Du, do you think the Emperor can use this fish tank?" Master Zhang was instantly dissatisfied. This old man usually looked down on the Ministry of Works, thinking they were just a bunch of lowly craftsmen. Haha, this is a gift for the Emperor, and he dared to speak so arrogantly. Humph, I'll see if I don't peel off a layer of skin from you today~~~

"Your Majesty, I do not mean that. Please forgive me, Your Majesty."

"Lord Du is old, so I guess he didn't hear clearly. The cost of this glass is less than five hundred coins for such a big piece. This fish tank costs at most two taels of silver." Prime Minister Gu also spoke up, not for anything else, he just wanted it!

Prime Minister Gu loves to raise fish. He has a precious golden koi at home. One can’t imagine how happy the old boy would be if his precious koi lived in such a beautiful fish tank!

"In reply to Your Majesty, this fish tank is made of a mold, and the scenery inside is made of water plants and stones. The cost of this fish tank is a bit more expensive than the Prime Minister guessed, it costs three taels of silver. The main reason for the high cost is the time it took me to create the scenery." Gu Can's words dealt a heavy blow to Lord Du.

"So cheap? You're the top scorer in the imperial examination and a minister of the Ministry of Works. How can your labor be so cheap? Regardless of the cost, your craftsmanship alone is worth a hundred taels of gold. I'll reward Minister Gu with a hundred taels of gold."

"Thank you, Your Majesty, for the reward."

The harmony between the monarch and his subjects was the last straw that broke the camel's back for Lord Du.

"Your Majesty, please forgive me. It's my fault that I didn't know the value of it. I just thought that such exquisite craftsmanship must be worth a lot of money. I am narrow-minded." Lord Du has been an official for many years and his reaction is quite quick.

"Mr. Du has been in the court for many years, and I know your character. However, you cannot only look at things with old eyes. I will fine you one month's salary as compensation to Minister Gu."

"I thank the Emperor for his grace. Minister Gu, I was rude to you."

"Master Du, you're welcome." Gu Can responded naturally. The underlying thoughts were obvious to everyone, and there was no point in exposing them. She also didn't want to argue with these people; that would only be a waste of time.

The turmoil caused by this naughty little fish seemed to have passed. In fact, what these people were thinking was only known to them.

At this time, Wu Zhubu had already taken out the last thing that Gu Can wanted to give him from the room.
