Zhao Hanzhang clapped her hands, and immediately guards carried over two large chests, opening them directly, giving everyone present a shocking opening.

Oh, except for Professor Fu. Even Ting He was seeing so much glass for the first time. Even the guards carrying them had their mouths wide open, not expecting the chests they carried contained such treasures.

Zhao Ming was the first to recover, looking at Zhao Hanzhang in astonishment. “How do you refine this?”

Zhao Song also came to his senses, glaring at Zhao Ming before saying, “Is this something you can ask about?”

But he also turned to ask Zhao Hanzhang, “Is this formula something your grandfather left you?”

“No,” Zhao Hanzhang directly denied, pointing at Fu Tinghan. “This is Young Master Fu’s formula.”

Zhao Song breathed a sigh of relief. He had thought so—if his elder brother had such a good thing, how could he hide it away?

Zhao Ming’s heart tightened, and he couldn’t help looking at Fu Tinghan.

Fu Tinghan sat very quietly, watching quietly. The surrounding events seemed unrelated to him. Seeing Zhao Ming look over, he even smiled and nodded at him.

Zhao Ming felt he hadn’t misjudged the person. Although Fu Tinghan was younger than his father, he believed he had traveled more roads and seen more people than his father.

So he could see Zhao Hanzhang’s restlessness and ambition.

And Fu Tinghan, though cold and distant, had gentle eyes and brows—this was truly someone with no desires who could be unyielding.

Zhao Ming looked at Fu Tinghan, then looked at Zhao Hanzhang again with a changed expression. Previously, he had always worried that after marriage, Zhao Hanzhang would use her ambition to extract things from the Zhao clan for the Fu family. But now it seemed he was completely wrong.

She clearly intended to extract things from both the Zhao and Fu families together to strengthen herself!

Zhao Ming looked at his father sympathetically, then turned to look sympathetically at Fu Tinghan. He really couldn’t join in their happiness. Finally, he gave his sympathy to himself.

The feeling of being the only sober one among drunkards wasn’t good. The most pitiful wasn’t the drunk crowd, but that clear-headed person!

He had so much to worry about.

Though Zhao Ming very much wanted to speak privately with Zhao Hanzhang, thinking of their previous exchanges, he still suppressed this thought.

Forget it. Some things said too transparently actually lose their beauty. Anyway, they both understood each other’s hearts.

Zhao Ming deflated like a balloon and poured himself a cup of tea, then casually poured one for Zhao Hanzhang as well. “Sanniang, what excellent methods you have.”

Zhao Hanzhang impolitely accepted this praise, raising her cup. “Father is too kind.”

Zhao Ming took a sip of tea, once again regretting inwardly. How wonderful it would be if Zhao Zhi were still alive, or if they had just given birth to Zhao Hanzhang as a man!

If the Zhao family had such a man, he could set off millions of firecrackers in celebration.

Thinking of Zhao Ji and Zhao Yi in Luoyang, Zhao Ming gloomily downed a cup of tea, nearly choking.

Tea really was bitter. Wine tasted better.

Zhao Song was already circling the two chests, taking out the glass products inside. Seeing their thickness and transparency varied greatly, he couldn’t help being curious. “Why is there such a big difference between different glass items?”

Zhao Hanzhang looked at Fu Tinghan.

Fu Tinghan explained, “Different material ratios produce different results.”

Zhao Song looked kindly at Fu Tinghan and asked, “Changrong, how did you obtain such a formula?”

He had heard the Fu family wasn’t very wealthy. At least compared to their Zhao family, they were far behind.

Compared to Zhao Changyu who was skilled at management and saving money, Fu Zhi was upright, honest, devoted entirely to government affairs and water conservancy projects. Who could have thought his grandson would know the formula for refining glass, yet instead of giving it to the Fu family, he refined it in the Zhao family?

Zhao Song almost suspected their grandfather-grandson relationship.

Fu Tinghan said, “I saw it in books. Some books record that after volcanic eruptions, glass crystals are produced. So the necessary condition for glass production is high temperature. As for materials, those near volcanic craters are all possible. With more research, reading more books, and eliminating them one by one, it works out.”

Not only Zhao Song, even Zhao Ming was shocked. “It’s that simple?”

Fu Tinghan couldn’t very well tell them that this kind of process that could be made public in modern times wasn’t difficult for him at all. What was difficult was those processes that weren’t made public.

But as long as Zhao Hanzhang didn’t demand glass as strong as steel, or other polymer glass, he could deduce and calculate it—just a matter of time.

Zhao Ming also stood up and walked into the courtyard, standing beside Fu Tinghan, curiously asking, “What books do you usually like to read, Changrong?”

“I like reading books on mathematics and technical subjects.”

Not many people liked such things nowadays. Zhao Ming said, “You’ve truly inherited Scholar-Official Fu’s strengths.”

Fu Zhi’s most famous achievement was constructing the Shenlai Dam, eliminating water disasters in Yanzhou and Yuzhou. Oh, this was Yuzhou.

So Fu Zhi had an excellent reputation here. This was also one reason Fu Changrong was so popular here.

He could freely enter and exit the Zhao clan wubao with Zhao Hanzhang before marriage, firstly because of his filial piety, and secondly because of Fu Zhi’s good reputation in Yuzhou.

Even the people in the Zhao clan wubao were grateful for Fu Zhi’s kindness in eliminating the water disaster.

The more Zhao Ming looked, the more he felt Fu Tinghan was gentle. Looking again at Zhao Hanzhang who was fawning around his father, he couldn’t help sighing deeply. He reached out and patted Fu Tinghan’s shoulder. “Changrong, I really don’t know whether it will be my Zhao clan wronging you, or you wronging my Zhao clan in the end.”

Fu Tinghan said, “…Father, our two clans are marriage relatives, a bond between two surnames. Can’t the Zhao clan and I achieve mutual benefit?”

Zhao Ming’s gaze fell on Zhao Hanzhang, saying with difficulty, “I always feel it’s somewhat difficult.”

Zhao Song had finished looking and turned back to see the two whispering. He asked, “What are you two saying in secret?”

Zhao Ming’s state of mind had progressed again, so he liked Fu Tinghan even more now. He said, “I said I want to give Changrong a courtesy name.”

He turned to Fu Tinghan. “I remember after the new year you’ll be seventeen, right? Your age isn’t small anymore. We can give you a courtesy name early. If you don’t mind, I’ll give you a courtesy name?”

Zhao Hanzhang said, “Father, you’re too late. He already has a courtesy name.”

Zhao Ming asked, “What courtesy name did he take?”

“Tinghan.”

Zhao Ming was puzzled. “What does this mean? Since you took the given name Changrong, then you should…”

“I think this courtesy name sounds quite nice, rolls off the tongue easily. Oh right, Father, Fifth Great-Uncle, I also have a courtesy name.”

“I know,” Zhao Song said smiling. “Your grandfather mentioned it in his last letter, saying he gave you the courtesy name Hanzhang, and asked me to find a way to record it in the clan register. However…”

Zhao Song looked troubled.

Zhao Hanzhang expressed understanding and didn’t insist. “Whether it’s recorded or not doesn’t matter. As long as Fifth Great-Uncle remembers me, that’s enough.”

For women, even getting into the clan register wasn’t easy, let alone having their names recorded.

That she could have an entry in the clan register with “third in line, named Hezhen” was already good. To add more, unless one day she soared so high the Zhao clan had to look up to her, then they would very proactively add her courtesy name and various other achievements.
