At night, the Shigongshan quarry in the south of Xishan Island finally quieted down.

On the three-mile-long stone pier below the quarry, the torches still shine brightly in the sky.

It was the men pushing the carts and loading the ships overnight.

Liang and Miwa waited until this moment before it was their turn to row the boat to the dock.

At this time, the steward of the quarry asked them to show their red heads.

It was the day before departure, and I received it from the prefecture, and it had a unique number and the size of the boat.

The steward lit the torch, wrote down the number, and then stamped it on it, handed it back to Liang, and gave her four meal tickets.

The steward shouted: "One material! ”

So the man carried the stones in the basket to the couple's boat, and when they had loaded six baskets, they stopped.

The waterline reached the side of the ship at once, but fortunately, after the two men went down, it rose a little higher.

"Get out of the way, get out of the way." The steward waved his hand and told them to leave quickly.

The two of them cautiously steered the boat, avoiding the dense large and small boats on the dock, and went outside to find a berth.

Fortunately, their boat was small, and they found a place to stop less than a mile from the dock.

Then the two got off the boat and walked to the big canteen not far away, and with two meal tickets, one of them received a large bowl of brown rice, a pickled herring, and a bowl of bitter gourd soup with egg splashes.

Miwa ate a half-salted fish, a bowl of half-rice, and burped.

"It's so delicious!" Half-sized son blissful straight bubbling. "Just rush this salted fish, and I will pull stones every day."

"Look at your little talent, I don't think it's any different from a salted fish." Liang smiled and glanced at him, but this Jiangnan company is really wealthy, and it can actually marinate fish so salty.

I heard that there are big salt merchants among the shareholders, so they are willing to put salt, it must be right.

After eating, the mother and mother went back to the boat and squinted. When the sky was bright, Liang got up, and with the remaining two meal tickets, he went to get four steamed buns, two salted duck eggs, and also made cold white water.

took it back to the boat and called Miwa to come, and the two of them ate the bun with salted duck eggs, and then hurried to return.

~~

All the way back downstream. Although fully loaded, it is very time-saving and labor-saving.

Before noon, the boat returned to Kunshan. On the back of the skewer is written the paragraph number 'Twenty-two'. Although Liang is illiterate, he still knows each other from one to ten.

The two rowed the boat to the twenty-second section. Soon after the sticks were lit, someone came up, hooked the basket with an iron hook, and hoisted a basket up the embankment.

After the last basket was hoisted, Liang Chang breathed a sigh of relief, and this time the task was finally completed.

The two of them rowed a boat and deliberately made a long detour from the Xia River back to the county seat. Because Li Hua is here to repair the sluice.

The rivers in the south of the Yangtze River are vertical and horizontal, and there are six tributaries to the north on the Wusong River in the sixty-two miles in Kunshan.

These six parallel rivers provide drinking water, irrigation and travel convenience for the people of Kunbei, and it is impossible to block them all at once.

It is necessary to set up a gate, open the gate for boats at ordinary times, and close the gate to prevent flooding when the flood comes. This is also the difficulty of the entire embankment project.

Fortunately, there is Pan Jitao.

Pan Zhongcheng and Zheng Ruo once braved the wind and rain, ran all the rivers, and after repeated deliberations, they designed different sluices for the six rivers.

Just like the ten-zhang wide Xia Jiahe River, he adopted a double gate design on the left and right, and each gate has a front and rear gate. Also carved water ruler on the side of the gate, when to open a gate, when to open a double gate, a look to know.

In the past, it would have taken more than half a year to build the sluice gate of the Xiajia River, but now with concrete and prefabricated slabs, the project is much simpler.

The gate is made of prefabricated panels with bamboo bars and poured elsewhere.

The sluice chamber and pier are directly poured with concrete using the plate construction method.

The so-called plate construction method is an ancient architectural technique. To put it simply, the frame is built with wooden planks, supported by wooden stakes and sticks, and firmly bound with ropes to ensure firmness, and then filled with earth and rammed.

Most of the city walls, even the Great Wall, use this technique.

In fact, the high-rise buildings 400 years later were also poured in the same way.

Zhao Hao originally planned to teach the craftsmen the method of pouring, but when he saw that people had ready-made methods, he didn't get an axe.

In the end, he only reminded Pan Jitao of two points. First, when the concrete solidifies, it will be exothermic, and it is necessary to pay attention to watering to cool down. Second, when pouring, workers should be tamped with sticks to eliminate gaps and make the concrete dense and combined.

In fact, this is a place that should only be paid attention to in large-scale projects of tens or hundreds of meters in later generations. At the moment, it is only a matter of pouring a sluice gate a few meters high, and neither of these two points is a big problem.

A hundred years after the birth of concrete, who knows these things? Still not doing it right?

But the stakes are too high. Zhao Gongzi would rather be cautious than have any hidden dangers.

This made Mr. Pan look at him with admiration, and felt that this idle boy also had some permissions.

~~

The two women drove the boat and entered the gate of the earthen embankment, where they saw a group of craftsmen busy on the scaffolding made of bamboo.

When Miwa saw it, she saw her father working at the highest place.

"Daddy, Daddy!" He waved excitedly and shouted.

"Hey! Good son! Many craftsmen replied in unison: "What about your mother! ”

"Your mother, you want to die quickly!" Li Hua laughed and scolded, threw a brick knife and mud to go down, and rewarded those cheap mouths.

He beckoned to his son, smiled at his wife, and then threw a grass carp weighing more than three catties into the cabin from a high place.

"It burned at night."

In the morning, the gate was closed and dredged, and he really caught a lot of big fish, which was the one he was distributed.

Liang also smiled sweetly at her husband, and slowly shook the oar back.

~~

In the evening, the mother and wife finally returned to the county seat, handed in the sign at the wharf, and received the 'subsidy' for this running boat - four catties of rice, two taels of oil and three coins of salt.

If they were a second-material ship, they would be able to receive twice as many supplies. The two of them saw with their own eyes that a big ship of fifty ingredients in front of them took away two bags of rice, a large barrel of oil, and a large bag of salt.

Although it takes a dozen or so people to handle such a big boat, it is still much more cost-effective than their small boat.

Hey, you shouldn't think like that. We didn't go out to make the county's benefits.

Liang was deeply ashamed of her selfishness, in fact, to a large extent, she took a fancy to the ship more than the basket......

The two put the fish, grain and oil into the basket and happily returned to their home in Xin'an Minshe.

Liang asked his son to hurry up to pick up his younger siblings and pick up a load of water to come back.

She hurriedly opened the door and put down the basket to deal with the big grass carp.

After a while, I survived, and it was dark.

The light of the fire in the fire pit was bright and warm, and the fish soup in the pot was full of fragrance, and the child next door cried again.

The children gathered around the fire, sniffing and grunting.

At this time, the door opened, and Li Hua came in with a flat burden.

"Daddy's back!" The youngest son and the youngest daughter cheered, jumped up to meet him, and threw himself into his father's arms. "It's finally time to eat."

"I'm back, let's wash and eat." Liang also got up and took her husband's burden.

"Well, you've worked hard too." Li Hua reached out and touched his wife's face.

Under the reflection of the pond fire, her face was flushed.
