Dongming Ziyu gave a faint hum, fed the melon seeds in his hand to Shangguan Ruoli, gave the tenth prince a knife, and said coldly: "Where are the etiquette? Did you eat them all?"

The expression of the tenth prince changed slightly, and he hurriedly bowed and bowed in a formal manner: "My younger brother has met the eldest brother and the eldest emperor's sister-in-law!"

"Hurry and excuse yourself!" Shangguan Ruoli handed him the plate with the snacks at hand, "Have a taste."

The tenth prince glanced at Dongming Ziyu carefully, took the plate and held it in his arms. His eyes lit up when he saw the snacks on the plate, "Why are there so many colors?"

Shangguan Ruoli said with a smile: "It's made with vegetable juice and noodles. What kind of vegetables can you guess?"

The tenth prince swallowed a sip of saliva and reached for some snacks.

Dongming Ziyu frowned and said, "Go and clean your hands first!"

The tenth prince quickly retracted his hand, handed the plate to the little eunuch beside him, and followed Sassoon to wash his hands.

The fifth prince smiled and said: "Elder Sister-in-law, guess what I brought this time?"

Shangguan Ruoli looked at his expression of showing off and asked for praise, and said calmly: "Is it a glass plate?"

"The elder sister-in-law is smart!" Shangguan Ruoli guessed it right at once. The fifth prince was not interested and clapped his hands, and several guards came in carrying several large wooden boxes.

Look at the bend of the wooden stick that lifts the box. The wooden box is very heavy.

Shangguan Ruoli stood up and wanted to look directly over the railing of the corridor, but Dongming Ziyu put his arm around his waist and said, "Be careful!"

"..." Shangguan Ruoli was embarrassed and wanted to walk up the steps, but he was picked up by Dongming Ziyu, who used the railing to fall into the middle of the yard.

The fifth prince's eyes dimmed slightly, and he ordered someone to open the box. Inside were pieces of glass plates with straw in the middle to absorb shock.

Although the transparency is not as good as modern glass, it is not far behind.

"Okay, great!" Shangguan Ruoli already fantasized about sitting in front of a bright glass window and reading a book, or enjoying the rain scene on a rainy day, or watching the snow flying in the sky on a snowy day.

The fifth prince sighed: "The hardness of the glass has been achieved, but cutting it is not easy. I'm afraid I have to use a black iron dagger."

Shangguan Ruoli slapped his forehead and forgot about it, saying, "Do you know a kind of diamond? It's very hard and translucent."

The fifth prince shook his head, expressing his ignorance.

Dongming Ziyu said: "I have seen that in some stone gambling places, white and transparent stones are sometimes cut out. Because they are too hard and difficult to process, they are often thrown away as waste stones."

Shangguan Ruoli felt a pain in his heart. A pure natural diamond can cost tens of thousands or even hundreds of thousands per gram in modern times.

"Diamond is the hardest stone. Polish the diamond into the shape of a drill bit and set it on an iron drill to make a glass knife. With just one stroke, the glass will be cut."

The fifth prince's eyes lit up, "I'll go find him right away!"

Mo Wen hurriedly said: "Your Majesty, I remember that when I was in the northwest, someone gave the prince a batch of jadeite stones. I remember that there was a white and transparent stone on the stone. At that time, the man said that it was not valuable. I still have it.

It’s a pity.”

Dongming Ziyu said: "Then you take the fifth prince to the warehouse to see if there is anything left."

"Yes!" Mo Wen turned around and took the fifth prince to the warehouse.

"Hey!" Shangguan Ruoli stopped him, "Leave a piece for me, this thing will be valuable in the future!"

The fifth prince raised his eyebrows, "Why?"

Shangguan Ruoli's eyes sparkled and he said: "It can be made into a diamond. It can be cut into many planes. Each plane can reflect sunlight. The effect will be radiant and very beautiful. It also has a good meaning!"

I believe there is no woman who doesn’t like sparkling diamonds, it’s a woman’s nature.

However, due to processing technology issues, the effect cannot be achieved here, so people prefer colored jade and gemstones.

Seeing her eyes shining, Dongming Ziyu asked in a dignified manner: "What's the best meaning?"

Shangguan Ruoli said: "Because diamonds are hard, they are synonymous with eternity, symbolizing unswerving love. Diamonds last forever, and true love lasts forever; my heart is like a rock, dedicated to you forever..."

Shangguan Ruoli said several advertising slogans in succession, looked at his bare fingers, and couldn't help but feel regretful.

The fifth prince's eyes lit up, he clapped his hands and said: "I have another way to make money. Although there will be imitators soon like hot pot, the first batch of money is ours!"

"You can try it first!" Shangguan Ruoli picked up a branch and drew a sketch of a diamond on the ground, explaining the appearance of a diamond and the principles of reflected light and refracted light.

"Set the diamond on the ring." Then he drew a few sketches of the diamond ring. "With that meaning, when men and women get engaged or get married, they will exchange diamond rings."

Shangguan Ruoli pointed to his ring finger, "Wear it on this finger, because the blood of this finger is connected to the heart, which means tying each other's hearts."

The fifth prince seemed to see a lot of silver flying towards him, "Just in time, I hired a jewelry master to make glass jewelry and let them design some patterns."

Shangguan Ruoli nodded, "You can use the similarity to your heart's content and give the diamond jewelry a beautiful and meaningful name. It can also be used in conjunction with other gemstones."

The fifth prince pulled Mo Wen and said impatiently: "Come on, let's go to the warehouse to look for it. If it's not there, we have to find another way."

Wang Feng didn't know when he came. He looked at the picture on the ground intently and asked Shangguan Ruoli: "Princess, does the diamond really attract girls so much? Does it have such a meaning?"

Shangguan Ruoli stood up and said with a smile: "Of course, if you propose to Bai Qingqing with a diamond ring, she will definitely agree! In this way..."

Shangguan Ruoli knelt down on one knee towards Dongming Ziyu, pretending to hold up a ring, "My dear Qingqing, promise to marry me! From now on, no matter it is good or bad, rich or poor, healthy or sick, happy or

Sad, I will love you unreservedly, be loyal to you, and never leave you, forever!"

Dongming Ziyu moved slightly, held her hand tightly, pulled her into his arms, and said in a deep voice: "I will be with you forever, and I will never leave you!"

Both Rejoice and Sassoon burst into tears imagining the scene of being proposed to them like this. If their fiancés made such vows, they would follow him even if they were begging for food.

"Brother, how can you hug the elder sister-in-law like this in public? Etiquette, etiquette!" The tenth prince imitated the way Dongming Ziyu scolded him, with a sullen face.

If you ignore the snack plate he is holding and the snack dregs on the corner of his lips, it really looks like that.

Dongming Ziyu let go of Shangguan Ruoli as if nothing had happened, coughed slightly, and said seriously: "Your eldest sister-in-law almost fell, but I was helping her!"

The tenth prince's little face was tangled up in confusion, and he was obviously dubious.

Dongming Ziyu lost his etiquette in front of the little bun, his ears were a little red, and he asked Wang Feng: "But I have something to report?"
