Meng Xin said that this kind of well is called a qanat, which is composed of four parts: a shaft, a culvert, an open channel and a waterlogged dam.

In general, the construction principle of the qanats is to first search for water sources in the undercurrent of high mountain snow water, and then drill shafts of different depths at a certain interval.

Then, according to the terrain, a culvert was built at the bottom of the well to communicate all the shafts and divert the snow water down the mountain.

At the bottom of the mountain, the outlet of the underground culvert is connected to the channel on the ground, and the snow water from the shaft is diverted to the surface to form a river.

Su Mo'er nodded when she listened, this method is really good, just listening to her can understand, it's just that this is a big project, will the people of Wujin Kingdom believe it?

Meng Xin knew Su Mo'er's worries, so she would extract her memories, as long as they drew a pattern, they would be convinced if they had a specific situation.

After an hour, Meng Xin opened the box, and a golden butterfly flew out of it, and the butterfly kept scattering golden powder.

Meng Xin spread out the large sheet of drawings prepared in advance, the paper was all black, and the golden powder fell on it, forming a stark contrast.

Kingdee kept flying, the powder sprinkled on the paper, and gradually formed words and pictures, and the grand project jumped onto the paper.

Su Mo'er looked at it, her heartbeat accelerated, this drawing will definitely change a lot of things in the future, she doesn't know whether it is right or wrong to give it.

It's just that when she thinks of Su Xiu'er, she has strengthened her mind again, even if it will affect the development of future generations, she will not regret it.

She has made up her mind that she must treat Su Xiu'er well and repay the debts of her previous life, as long as she can be safe and worry-free, she can do anything.

She also has selfish intentions, she just wants to be good to the people she cares about, and such a long-term thing that affects the fortunes of the country, sorry, she doesn't want to think about it now.

After another half an hour, the Kingdee was finally painted, and the butterfly turned into the last bit of powder and fell onto the paper.

Meng Xin rolled up the drawings, stuffed them into a long wooden tube, and handed them to Su Mo'er. Su Mo'er took the wooden tube and said gratefully:

"Meng Xin, your gift is really too heavy, I really don't know how to thank you. ”

"Hehe, this thing is just a memory for me, and it's a matter of effort to help you. Just as my thank you, your sister saved me once before. ”

The life-saving grace that Meng Xin said was when Meng Xin had not recovered her memory and was in distress in the palace.

At that time, it happened to be the Hundred Flowers Society, and Su Mo'er accidentally learned that Meng Xin was being pursued by the guards, so she asked her brothers and sisters for help and let Meng Xin escape.

All this is fate, all the people who had no intersection in the previous life, for various reasons, came together in this life and intersected with each other.

It wasn't until the day before Su Xiu'er got married that Su Mo'er went to see Su Xiu'er with the drawings, and slept with Su Xiu'er for one night by the way.

This night, the two sisters were destined to be unable to sleep, and the two of them suddenly had endless words, and they did not feel sleepy at all.

Su Mo'er handed the drawings to Su Xiu'er and informed her of the importance of the drawings inside, and Su Xiu'er's eyes widened in shock.

This thing is definitely the treasure to save the Ugin Kingdom, and at this moment, it is in her hands. Su Xiu'er felt a bit like a dream.

"Mo'er, is it really good for me to accept such a valuable thing?"

"This thing is the weapon that determines your status in the Ugin Country, you must accept it, give it to you, it is yours. ”

"I feel a little unreal, how can I have such a ......"

Su Xiu'er couldn't find words to describe it for a while, as if she was in a mood at the moment.

"Hehe, don't worry, this method is actually very simple, it takes too much time and manpower. ”

"It's going to be discovered sooner or later, and you're just bringing it up in advance. ”

Being comforted by Su Mo'er like this, Su Xiu'er actually calmed down a little, and she gratefully held her sister's hand.

The two of them didn't speak again, and the temperature of each other's palms passed from their fingers to each other's hearts, and at this moment, silence was better than sound.

On the second day, the two sisters got up early to freshen up, and then Su Mo'er personally cleaned her face and put on makeup.

Mrs. Su was one of the best beauties when she was young, and the appearance of the children she gave birth to was not bad, but Su Moer's face was too bright, and Su Xiuer was always ignored.

Su Xiu'er has grown so big, only this day is such a grand contouring and makeup, and after Su Mo'er said it, she looked in the mirror.

At a glance, she was stunned, she stretched out her hand and gently brushed the mirror, she couldn't believe that the delicate red-makeup beauty in the mirror was herself.

It was also the first time for everyone to see Su Xiu'er so coquettish, and Mrs. Su felt emotion in her heart, and her eyes couldn't help but moisten.

What she is most worried about is Su Xiu'er's marriage, and now that she is really getting married, she has a strong reluctance in her heart.

Out of Guancheng today, it is impossible to see each other in the future, and in the future, when my daughter becomes the imperial concubine, she can't do things as she did before.

Su Mo'er put the golden crown on Su Xiu'er, and decorated the exquisite hairpins between her buns one by one.

Her hands trembled slightly, and her face was forced not to show sadness, her sister should be happy that she can marry the person she likes.

During the grooming period, Mrs. Su took her daughter's hand and told her carefully, all of which were her life's experience and views, and she couldn't wait to teach her everything so that she could live well.

As she spoke, Mrs. Su burst into tears, holding Su Xiu'er's hand and crying, her whole body trembled, and Su Xiu'er was provoked to cry together.

Since she was a child, Su Xiuer felt that her mother preferred her sister, and in contrast, her mother was more laissez-faire to herself.

She is not without grievances, and she also longs for her mother's gentle treatment. It wasn't until she grew up that she gradually understood that her mother just wanted her to live as she wished.

In her life for more than ten years, she has lived a casual and chic life, and sometimes watching her sister being restricted by etiquette everywhere, she suddenly feels that her mother is actually very good to herself.

Now, the mother is crying so sadly, she does not have the reserved and noble posture of the noble lady at all, and some are just reluctant to marry her daughter.

When Su Mo'er got married, her mother didn't cry like this, but now, she cried like this for herself, and the last bit of resentment in Su Xiu'er's heart dissipated without a trace.

The mother and daughter hugged each other and cried bitterly, and the people in the room also cried with them, Su Moer was better, wiped away her tears, and comforted her mother and sister.

finally stopped her tears, but her makeup was spent, and Su Moer had to touch up her makeup again.

After the mending, the hour came, and the float to welcome the relatives stopped in front of the gate of Sufu, and the housekeeper led a few subordinates to light more than a dozen cannons.

The bride of Wujin Kingdom didn't need to cover her head, Su Mo'er took a golden tassel mask and put it on Su Xiu'er, and her red face loomed behind the tassel.
