Xue Zhaojin asked Xu Yin not to worry about this matter, if the East Courtyard was implicated, he should come to worry about it.

He asked her to pack her luggage and follow the four princesses to live in the newly purchased Zhuangzi of the four princes for a few days the next day.

"The fourth prince has received a new errand this year, build a glazed greenhouse according to the method you taught, and at the same time ponder whether there is a better way to reduce the cost of the greenhouse, so that the people can also eat fresh melons, fruits, vegetables and vegetables in winter."

Xue Zhaojin still didn't say a word: If this thing can be done, the fourth prince will not be far from that position.

It's not that I'm afraid that Xu Yin will know about the rumors, his wife's mouth is still quite strict, but in all dynasties, there are too many variables involving the throne, and until the last moment, no one is sure which prince will have the last laugh.

In fact, if Xue Zhaojin didn't say it, how could Xu Yin not think of this?

Whoever wins the hearts of the people wins the world!

Have you never eaten pork and seen a pig run, have you seen so many palace fights in later generations? Otherwise, it won't be brought into the world by the dog than the system.

The task of entering the palace to play and chat with me this month has been obtained, and it is not bad to follow the fourth princess to her Zhuangzi to live for a few days.

Once the matter of the second aunt is revealed, the old lady will inevitably be angry, can she hide or hide.

Xu Yin even wanted to take her mother-in-law with her, leaving her mother-in-law in the mansion for the possible bloody storm, but she happily followed the four princesses to go to another village outside the city, which was really unbearable.

Zhong Minhua couldn't stop laughing: "How can the four princesses invite you, and you still drag your family with you?" Not like that! Don't worry, the old lady is angry, and he will not implicate innocent people. Your second aunt can't get into trouble with me. Speaking of which, our East Courtyard is still the one that is being used by your second aunt, I still want to seek justice from the old lady, how can I leave at this time? Wouldn't it be cheaper for your second aunt to leave?"

「……」

It seems that the mother-in-law is just too lazy to worry about the second aunt on weekdays, and she really makes her anxious, and she is not easy to bully.

In this case, Xu Yin went out of the city alone with the four princesses.

The four princesses and the four princes are the same age, and they look like husband and wife, with a chubby round face, and a pair of pear vortices will bloom at the corners of their mouths when they smile.

The fourth princess is only eighteen years old this year, and the ancients got married early, and the eighteen-year-old woman already had a son and a daughter.

When she went out of the city today, she brought her two-year-old son and one-year-old daughter, one child with two nurses and four palace maids.

On the way, the four princesses would occasionally stop to check on the children in the carriage behind, and most of the time they sat with Xu Yin, drinking tea, eating snacks, and chatting.

Women, sitting together and chatting, it is inevitable to talk about some gossip from outsiders.

No, after chatting, the four princesses peeled the salt-baked pine nuts that Xu Yin brought her to taste, and talked about her concubine - the sixth princess:

"The sixth daughter-in-law thinks that she is in charge of the sixth child to death, and he is not allowed to bring messy women home, and when she brings them back, she will be thrown out, and the sixth woman will depend on her face. As everyone knows, the women who were thrown out were all placed outside by him, and they still warmed his bed and gave birth to children, but he was still laughing at the stupidity of the sixth daughter-in-law behind his back! In addition to not being able to enter the house, they are living a very free life, and they don't have to worry about being hacked by the sixth daughter-in-law. When the child is older, he will still go back to the house to fight with his son-in-law for the family property, and the sixth daughter-in-law thinks that her husband has skills."

"In the second half of last year, who was in your house, the one who ran behind the sixth child's butt all the year round, didn't he help the sixth child settle an illegitimate child? When can this be hidden from his brothers? The third, fifth, and youngest families, which one doesn't know? It's just that the sixth daughter-in-law was kept in the dark! Tsk!"

Xu Yin: "......"

Do I know too much?

Why don't I also tell some gossip about my concubine?

Otherwise, the light input will not be output, and I am always worried that the head and neck on the item will be separated at any time.

Fortunately, after listening to the six princesses' miscellaneous complaints, they went to the Zhuangzi newly purchased by the six princes.

Seeing the unfinished look of the fourth princess, Xu Yin breathed a long sigh of relief in her heart.

The melon of the royal family, fresh is fresh, but

It's too real and choked, so I can't eat her.

However, the Fourth Princess's Concubines dared to tell Xu Yin the secrets of the Sixth Prince's Mansion, which was nothing more than including her in the category of her own people.

Before going out, the fourth prince reminded her that Xue Zhaojin was the only one who could make him let down his guard and trust him unconditionally. There are some things that even the queen mother has to hide, but Xue Zhaojin can talk about everything.

Being people in the same boat, what else can't be talked about?

Thinking about this, Xu Yin sighed in her heart: Don't look at the four princesses, who are gentle and harmless, cute and lovable, and the round face of the baby fat smiles innocently, as if she grew up eating cuteness, but in the end she is the royal daughter-in-law.

Which one of the royal family will be stupid and sweet? 800 hearts and eyes per capita!

When I arrived at Zhuangzi, I happened to meet a group of craftsmen hired by the four princes who were gathering here in Zhuangtou to discuss.

The four princes asked them to find a way to reduce the cost of the glazed greenhouse, but the price of the glaze was there, and no matter how much they saved, they couldn't drop it.

The fourth princess didn't understand this, and the two children were clamoring for her to hug her, so they took the children to the back room first.

Xu Yin was idle, so she stayed and listened to the ideas of the craftsmen.

However, the craftsmen have always been discussing the topic of "glass", this proposal to use "inferior glass", that suggestion to find a glass manufacturer, can the cost be reduced if the quantity is large......

Xu Yin couldn't help but interrupt them: "Haven't you thought about replacing the glass with other materials?"

"Anything else?" The craftsmen were confused, "The glass is so special, what other material can be used instead?"

"Absolutely. It may not be as good as the glass in the initial stage, but we can find ways to improve it."

Xu Yin pointed them in the direction, that is, the oil paper used to make oil paper umbrellas.

"That's right!" The craftsmen suddenly realized, "Oiled paper can also protect from the wind and rain!"

"But the light transmission of oiled paper is worse than that of colored glass." Xu Yin followed the temptation, "You see if there is any way to make the oil paper thinner and more transparent, and it is best to bring some toughness, so as not to tear it off."

"This ......"

Xu Yin saw that they were in trouble, and said with a smile, "Don't worry, it's just late spring, and it's still early before the end of the year." Ponder it slowly, and maybe you can find an umbrella maker to figure it out."

The craftsmen's eyes lit up when they heard this: yes! The oil-paper umbrella is made by the umbrella maker, so wouldn't it be good for the umbrella maker to find a way to make the oil-paper thin and transparent? The four princes only said that they should think of a way, but they didn't say that this solution must have been figured out by themselves, and they can also ask others for help! Just tell the umbrella maker that they need a batch of oil paper that is thinner, more permeable and tougher than the existing oil paper, and does not mention the matter of the glass greenhouse, which is not against the orders of the four princes, right?

So, there was an umbrella shop next door to my house, and I hurried back to the city to implement this method.
