The Three Spirit Stones

At the end of the year, the soap factory distributed dividends. After deducting all expenses and reserved funds, the Sun family and the Cao family each received more than 800,000 taels of silver, which made General Sun so happy that he was grinning.

In exchange of gifts, the matrons of the Cao and Sun families each sent generous gifts to the women of the Cheng family, including a gift for Ah Cai.

She looked at the dozen or so boxes of exquisite jewelry displayed in her living room and exclaimed in amazement!

These are the painstaking works of ancient skilled craftsmen, and can only be seen in museums today.

But now, she can actually have it, how can she not be excited, she looks left and right and can't get enough of it!

She picked up a pair of gold filigree bracelets with kingfisher feathers and looked at them for a while, then picked up another gold headpiece inlaid with gemstones and looked at it for a while, and finally picked up the pair of mandarin duck-shaped golden hairpins and said to Cuizhi who was standing next to her with emotion, "Grandma Cui, look at these two ducks. They are so beautifully made!"

Cuizhi pulled the corner of her mouth and said to her, "Madam, this is not a duck, it is a mandarin duck."

"Oh! Yes, they are mandarin ducks, they have crests on their heads! But why are there two males? Females don't have crests on their heads!"

"……this?"

Cuizhi didn't know how to explain.

"Hahaha! I get it, they are gay,"

She was so happy that she was a little incoherent!

When Cheng Yu came back in the afternoon, she was still admiring them, happily showing them to him.

Seeing how happy she was, Cheng Yu told her that he would take her to the Golden Tower when he had time.

……

"I want to put these jewels in a glass box, just like in a museum, so that they can be seen at a glance without getting dusty. What do you think?"

Cheng Yu asked, "Don't you think you can wear it if you put it on?"

"I don't want to wear such a precious ornament, I just want to admire it. Just get me some glass boxes!"

"Okay! I'll go look for it!"

The next day, Cheng Yu went to Bianjing City specifically to look for glass. After walking around for a long time, he did find some glass products, all imported from Southeast Asia. They were called colored glaze here, but they were all colored and very valuable. It seemed that there was no transparent glass here.

I went home and talked to her about this problem and asked her if there was any way she could do it herself?

Ah Cai said that to solve the problem of transparent glass, we must first solve the iron element contained in silica.

Because green glass contains iron, it requires a temperature of at least 1,200 degrees. To reach this temperature, charcoal cannot be used, and coke must be used.

First, coking coal is used to make coke. Once the coke is made, a blast furnace and a blower can be used to make iron and steel.

Industrial technology has never existed independently; it is interconnected like a spider web. The use of coke was a major industrial milestone that took mankind half a century to develop.

Cheng Yu asked again, what should we do first?

She said that first of all, we need to find coking coal, which should be clean coal with sufficient coking properties after washing. Then, she wrote him details of where there were open-pit coal mines that were easy to mine and how to wash the clean coal.

The next two steps are coal preparation and coking. Coal preparation is to prepare various clean coals into coal materials with accurate proportions, appropriate particle sizes, uniform quality, and meeting the requirements of coking.

Coking is to put the prepared coal into the coking oven, heat it up and perform dry distillation to make coke...

All of this took up dozens of pages of paper. Cheng Yu kept the information safe and planned to send someone to find coal for experiment first!

……

……

In the side hall of Cheng's mansion, a dignified general with sharp eyebrows and fierce eyes stood with his hands behind his back. Madam Cheng served him tea while talking to him with a smile.

"Fourth brother, you haven't returned home yet? You came here without even taking off your armor!"

"I miss Xu'er and want to see him soon. Sister Shu, every time I think of him in the past few years, my heart aches so much!"

"Fortunately! Fortunately! God bless, Xu'er survived the disaster, and he will surely have good fortune in the future!"

"God bless you! I hope so!"

Mrs. Cheng clasped her hands together.

After hearing Cheng Chang's news that his uncle had arrived, Cheng Yu immediately rushed home from the soap factory.

When he returned home and saw the familiar figure from afar, he couldn't help but get teary-eyed and shouted excitedly, "Uncle!!!"

Cao Wei turned around and saw that it was his nephew whom he missed day and night. He couldn't help but get excited.

"Xu'er!! It's really you! It's really you!"

Cheng Yu's death has always been a knot in his heart that he can't get over.

His sister entrusted her only son to him, but he betrayed her trust. How could he be worthy of his dead brother-in-law?

At the beginning of the year, he received a handwritten letter from his sister saying that Cheng Yu had returned safely. He was very skeptical.

He was well aware of the tragic casualties at Yunwu Mountain.

The enemy outnumbered us, and we were almost completely wiped out! After being shot by arrows and falling off such a deep cliff, the chance of survival was almost zero!

But now, my sister said that my nephew is still alive.

At first, he thought that maybe his sister missed her son so much that she was confused and someone pretended to be her son to deceive her. He also wrote to his two sons in Beijing to ask, and the reply he got was true.

Then he personally communicated with Cheng Yu, and he could accurately describe the handwriting and details of past events. At this time, he believed it 90%.

The only difference was that he found that his nephew now had much more experience and knowledge than he did a few years ago. He seemed to be the same person but also not the same person. So as soon as he returned to the capital, he was eager to meet Cheng Yu.

Now seeing him standing in front of him alive, he could not hold back his tears!

"Uncle! I'm back!"

Cheng Yu couldn't help but burst into tears and said,

Compared to his biological parents, he actually spent more time with his uncle. In order to cultivate him, Cao Wei often taught him by words and deeds and took him with him wherever he went, so he had deep feelings for him. For him, although they were separated by a thousand years, this feeling has not been erased.

The uncle and nephew supported each other's arms, crying and laughing!

"Okay Xu'er, your uncle has just come back from traveling and hasn't even had a meal yet! Why don't you invite your uncle to the table quickly?"

Madam Cheng pointed at the banquet filled with wine and food.

"Yeah! Yes, yes, uncle, please sit down!"

Cheng Yu pulled Cao Wei to the table.

The three of them sat at the table, eating and chatting. From previous correspondence, Cao Wei also knew that Cheng Yu was rescued by Acai's father, and that Acai was now his wife. However, for fear that the letter might be lost, the two of them tacitly agreed not to mention the details in the letter.

Now, they dismissed the servants, and Cheng Yu repeated what he had said to his mother. He could not hide it from his uncle.

Cao Wei was extremely surprised when he heard this!

As an old general who has fought on the battlefield for decades, his views on ghosts and gods are different from those of women.

The child is speechless and his strange power confuses the gods!

If ghosts and gods really existed, then wouldn't the millions of people who died on the battlefield be so numerous that there wouldn't even be enough space for a needle to penetrate?

But the person who said this now was his own nephew. If it hadn't been for the gods' help, given how serious his injuries had been, there would have been no way human power would have been able to save him.

At this time, Madam Cheng interrupted and said, "Fourth brother, actually when Xu'er told me, I didn't dare to believe it, but he showed me that thing, that machine, and I couldn't help but believe it."

“…Ah?!! What chicken???”

"Oh, it's not the chicken, it's the machine, Xu'er, show it to your uncle."

"Mom, that's a cell phone, it's Ah Cai's toy,"

"Oh, yes, yes! It's the cell phone,"

"But my phone is out of battery and won't turn on, but I'll take it and have a look anyway."

Then, Cheng Yu told Cuizhi outside to ask Acai to bring the phone over.
