Lin Xianyu looked at Mrs. Lin's mysterious smile, and suddenly had a guess, wouldn't her own mother also be involved in this matter?

"Girls' family, listen to less gossip." When Mrs. Lin saw Lin Xianyu's eyes, she knew that her daughter might have guessed something, and it is better for a girl to be smart than to be deceived.

"Xianyu, my mother was busy a while ago, so I didn't have time to ask you about the spring, can I tell my mother about the spring now?"

Mrs. Lin opened her mouth to ask Lin Xianyu, and Lin Xianyu thought that her mother had forgotten about it.

"Mother, I'll draw it for you." Lin Xianyu took a pen and paper and drew the spring to his mother, while explaining what was going on.

"To put it simply, the wire is wound around the cylinder to form the shape of a spring, and then a certain amount of heat treatment is carried out to change the properties of these wires, so as to become a usable spring."

In the end, Lin Xianyu summed it up, she didn't know how to get it, she only knew such a way of thinking.

After Mrs. Lin read it, she pondered for a moment, although it is said that there is a certain difficulty in making iron wire, but if it is only used to make a few springs, it is still very simple.

"This matter must be kept secret, this is related to the next development of our Lin family, although this spring will be discovered by others sooner or later, but you can make as long as you can make money."

"When you can't keep it secret, let your brother dedicate it to the court as a new invention, which can be regarded as a capital."

For a moment, Mrs. Lin had already thought a lot, and Lin Xianyu looked at Mrs. Lin with admiration, worthy of being a self-made mother.

When you can keep it secret, you can make a sum of money first, and when you can't keep it secret, you can dedicate it to the court, and the court will naturally credit it to your brother, which will be very useful for your brother's career.

No wonder the Lin family was able to prosper in a short period of time.

Madame Lin was a resolute person, and soon ordered the acquisition of a blacksmith shop and craftsmen, and signed death deeds and confidentiality agreements with those craftsmen before starting research.

As for Lin Xianyu, she naturally continued her happy life as a young lady, but occasionally she could hear a sentence or two of gossip about Su Ziheng.

The Su family and the Wang family quickly got married, and this speed is simply staggering.

The dowry of the Su family is said to be very rich, and I don't know if it has been stripped of the Wang family's old foundation.

Of course, it is said that the dowry of the Wang family is also very valuable.

If the two families of King Su were not afraid of affecting Su Ziheng's imperial examination, they really wanted to have a wedding before Su Ziheng's township test.

However, the Wang family promised that no matter whether Su Ziheng could win the lift or not, after this township test, a wedding would be held.

It is said that the second lady of the Wang family also went to the temple in person to ask Su Ziheng for a peace blessing.

It is said that the second lady of the Wang family also sewed a dress for her fiancé herself.

It is said that the second lady of the Wang family also personally gave a pair of faces to her future mother-in-law.

These are said to be what Mrs. Su said when she was proudly showing off, and she kept promoting the second lady of the Wang family, showing off her wisdom, gentle and virtuous.

Unlike a certain person, who has sharp teeth and sharp mouth, and will only talk back to his elders, he knows that he will lose even if he has gold and silver.

"Ha, when the second Miss Wang enters the door, Mrs. Su will know that she is suffering." Changshou relayed indignantly while saying with a sneer.

What kind of goods is that Second Miss Wang, they can see it clearly in the teahouse, and the Su family's door, which only entered by deception, will be lively when the time comes!
