Traveling through ancient times, the spy princess had everything going smoothly

Afterwards, everyone walked along the planned ditch route again and discussed how to divert water to nearby farmland after the reservoir channel is completed, so as to solve the irrigation problem of farmland as conveniently as possible.

The sun gradually sets, and the afterglow shines on everyone. Although a little tired, everyone's eyes are filled with firm belief and excitement for the future.

At dawn the next day, Qinghe and Baili Ye had already gathered at the foot of the mountain, and the craftsmen arranged by Pang Ziqian were also waiting in high spirits.

Qing He looked at everyone with a determined gaze and said loudly:

"Today's blasting is related to the foundation of Tailai County's water conservancy project. In a while, all the masters will work with me to drill holes, load explosives, and blast. Everyone must study each step carefully and be rigorous and meticulous. Safety is the first priority and no mistakes are allowed." Everyone responded in unison.

Qinghe took the lead and walked towards the blasting location selected yesterday, followed by everyone behind him.

She took out the chisel and hammer, handed them to the craftsman beside her, and said:

"Please, two masters, drill a hole at this location and drill to a depth of one foot. Be careful when drilling and don't hit your hands."

The two craftsmen answered "yes" and started to drill seriously. This kind of work was done frequently by the craftsmen on a normal basis. After a little guidance from Qinghe, the two of them started to do it skillfully.

In less than an incense stick of time, the two craftsmen had drilled the hole to a depth of one foot. After checking it, Qinghe said, "This hole is well drilled. Thank you for your hard work, masters."

She took the box of explosives and said:

"Next we'll start loading the explosives."

She looked at everyone and reminded them again about safety matters:

"Everyone remember, when loading explosives, you must strictly control the amount and check whether the fuse is intact." The craftsmen nodded one after another.

After arriving at the location, Qing He demonstrated it herself. She skillfully placed the explosives in place and explained each step in detail:

"The angle and depth of placement of this explosive are extremely critical, and are related to the effect and range of the blast."

The craftsmen gathered around, learning intently.

Baili Ye was directing everyone to set up a safety line. He arranged it in an orderly manner:

"Set up a cordon here and build a protective barrier outside the woods to ensure that the impact of the explosion does not affect innocent people." The bailiffs and craftsmen acted quickly to make the final confirmation.

Everything was ready. Qing He held the torch, took a deep breath, and shouted:

"Everyone retreat to a safe area!"

Everyone evacuated quickly.

Qinghe walked slowly towards the fuse with a focused look. After making sure that everyone was safe, she lit the fuse.

The fuse crackled and sparks flickered and spread rapidly.

With a deafening bang, smoke and dust rolled up, and rocks and soil were blown into the air.

Qinghe watched the explosion effect nervously, and when the smoke and dust cleared a little, she immediately went forward to check.

The expected gap was blown out on the hillside, and the surrounding mountains did not experience any abnormal conditions such as landslides. The huge rocks broke apart and became stones that could be moved by one person.

Qinghe showed a relieved smile on his face:

"It worked! The blasting was very successful! We can follow this procedure to blast before quarrying in the future."

Baili Ye also came forward and said with a smile:

"Xiao He's plan and arrangement are indeed ingenious. In this way, the subsequent reservoir and canal construction can proceed smoothly."

Pang Ziqian and the craftsmen he arranged also cheered and were full of confidence in the upcoming project.

Afterwards, Qinghe called everyone together and deployed the subsequent cleaning and excavation work, requiring everyone to seize the time and efficiently advance the project progress while ensuring safety, laying a solid foundation for the prosperity and development of Tailai County.

After several people went down the mountain, Pang Ziqian arranged for people to move the stones and started transporting the stones to the place where the canal was being built at the foot of the mountain.

They continued to head towards several blasting sites that they had spotted yesterday. The soil here was much softer and there were few hard stone walls, so blasting was easier.

They blasted all the way to the reservoir in the morning. As the last blast went off, everyone breathed a sigh of relief and started talking excitedly:

"After this series of explosions, the most difficult part of the project finally got a good start."

A craftsman wiped the sweat from his forehead, his face filled with joy.

"Yes, this solves a big problem. Otherwise, according to the previous practice, it would take several months to do what we did today."

Qing He looked at everyone and said with a smile:

"Everyone has worked hard, but this is just the beginning. The subsequent excavation, repairs and detailed construction of the channel will still require our concerted efforts."

Baili Ye nodded and said yes:

"That's right. Especially the construction of the canal, which is related to the direction of water flow and the accuracy of irrigation. Not even a little bit can be sloppy."

Pang Ziqian pondered for a moment and then said:

“There are not many people coming to work today.

After tomorrow, people from all over the country will arrive one after another, and the construction speed can be accelerated.

In this way, a group of people will be responsible for carrying the blasted rocks to the canal construction site;

Another group of people will build channels and reservoirs, level them and plan them. This two-pronged approach will speed up the project progress.”

Everyone agreed.

Qinghe said:

"Aye and I have already placed the cement, gravel, and sand in an unused farmyard nearby. We will take the people with us and I will teach everyone how to use them. Brother Pang can arrange for someone to look after the rest."

Pang Ziqian smiled and said:

"Okay, I'll send someone over in a moment. With these materials, the canals and reservoirs we build will be more solid."

Qinghe led everyone to the idle farmyard. The cement, gravel and sand piled in the yard exuded a rustic atmosphere under the sunlight.

She stood in front of the pile of materials, cleared her throat, and began to explain the usage in detail:

"Everyone, the ratio of cement to gravel and sand is crucial, just like the ratio of ingredients when cooking."

She arranged for several people to fetch water, and then took cement, sand and gravel in appropriate proportions and mixed them evenly. Then she dug a pit in the middle, poured water into it, and slowly mixed the materials evenly.

Qinghe demonstrated as she spoke. Her movements were skillful and smooth, and her eyes were focused and serious, allowing the craftsmen around her to see every step clearly.

The craftsmen listened attentively and asked their questions from time to time, and Qinghe patiently answered them one by one.

“When cement, sand and gravel are mixed together, they form a strong and durable building material called concrete.

Concrete can not only be used to build reservoirs and canals, but can also be used to build houses and bridges. In the north, city walls are all cast with concrete. Things built with it are strong, durable, and highly resistant to compression."

Then Qinghe taught everyone how to use it in daily life and what precautions to pay attention to.

After detailed explanations and practical demonstrations, the craftsmen gradually mastered the tricks of use and began to practice the operations eagerly.

After everyone had a certain grasp of the use of the materials, Qing He pulled Pang Ziqian aside and said solemnly:

“Brother Pang, this cement should be usable for a while, but there will be many places that will use cement in the future, so I will give you the method of making this cement.

We can open a cement plant. With the ability to produce our own cement, the engineering construction in Tailai County will be more independent and not restricted by too much external material supply.

Later, you can sell it to other places and earn some cash.”

After saying that, she took out a piece of paper covered with handwriting from her bosom, which recorded in detail the production formula and process flow of cement.

Pang Ziqian took the paper and looked at it carefully, with a look of surprise and gratitude on his face:

"Xiao He, you have brought another blessing to Tailai County. With the cement plant, we can not only meet the needs of current water conservancy projects, but also benefit other construction projects in the future."

Baili Ye smiled and said, "10% of the profits from this cement factory will be reserved for the county government for public use, the county magistrate, the county lieutenant, and the clerk will each get 10%, and our two families will each get 30%."

When everyone heard Baili Ye's words, they were all surprised.

Pang Ziqian was the first to react and quickly waved his hand:

“This cement factory could only be built thanks to your generosity, how could we take such a large share?

Moreover, this project is for the benefit of Tailai County. We, as public servants, have salaries to receive and should not share in the benefits.”
