Making you a son-in-law is not about making you conquer the world.

"I want a loving hug, I want a loving kiss..." Lin Ping shamelessly opened his arms, his thick lips curving upwards, waiting for Jiang Yunying's favor.

The effects of concrete are obvious to all. He believed that Jiang Yunying would understand what this meant for the main city. Once the parapet was raised infinitely, even if there were no soldiers in the city, the enemy would not be able to attack.

As is customary, Jiang Yunying would give herself some rewards, and Lin Ping's actions were simply an upgrade of those rewards.

"Yes, that's good." Jiang Yunying nodded in response, how could she not see through Lin Ping's little scheme?

"And then?" Lin Ping asked doubtfully. He couldn't just leave his arms hanging awkwardly in the air, could he?

“Then… my husband just does it.” Jiang Yunying spread her hands, making a helpless expression.

Lin Ping was completely speechless, and could only hope that Jiang Yunying would change her name to "That's all".

Just as Lin Ping was about to give up, Jiang Yunying's red lips suddenly appeared and hit the bullseye.

Lin Ping stared wide-eyed at Jiang Yunying, who was pressed tightly against him, his heart filled with shock. He wanted to playfully stick out his tongue, but found that she had already moved away.

Lin Ping licked his lips frantically, savoring the taste Jiang Yunying gave him. He hadn't expected her to be so proactive; it seemed like their wedding night was just around the corner.

"Satisfied now?" Jiang Yunying pouted and glanced at Lin Ping with annoyance. She acknowledged his talent, but couldn't understand why fate would bestow such talent upon such a scoundrel...

Lin Ping chuckled, but shook his head: "If we did it again, my husband might very well make even sharper weapons for the private army!"

That's a bit of an exaggeration. We've reached the pinnacle of cold weapons. The technology of forging steel through repeated tempering has long been available, and the warriors' steel blades are incredibly sharp, capable of cutting through iron like mud.

Besides these, all eighteen kinds of weapons are available, including a bizarre dragon bone whip. Forging an even sharper weapon is no easy task, though it's not impossible, given Lin Ping's modern mind and ability to improve the material of steel.

However, improving the steel material requires multiple experiments, and he doesn't have that much energy right now.

To be honest, Jiang Yunying was tempted. She was certain that Lin Ping had the ability and wanted to satisfy him, but she was also afraid that Lin Ping would become arrogant and reckless. This was also the way to manage a husband.

Men are always like this: what they can't get is always the best, and what they get is never appreciated. Even a beautiful woman like Jiang Yunying is no exception.

Therefore, Jiang Yunying should provide Lin Ping with benefits in a balanced way.

"Husband, you can't bite off more than you can chew," Jiang Yunying said with a double meaning, both telling Lin Ping not to get too big for his britches and making it clear that the private army couldn't accept too many new things right away.

After all, long spears and lances are easy to use, but if an airplane or cannon suddenly appears, you might not know how to use it.

Lin Ping scratched his head and chuckled dryly. He had naturally seen Jiang Yunying's angry gaze, but he didn't want a punch to land on his chest. Lin Ping really couldn't handle this kind of coquettish behavior.

Sometimes Lin Ping thought that it was inevitable for couples to have disagreements, and if they started fighting, he would definitely be the one who suffered. Perhaps he needed to exercise his almost deteriorating body.

He shares the same genes as Lin Xiaomei, so his talent for martial arts must be quite good. Even if he is no match for Jiang Yunying, he shouldn't have lost so badly.

Then, Lin Ping dashed to the kiln and began to meticulously explain the key points of calcining cement to the craftsmen. Every now and then, he would glance at Jiang Yunying out of the corner of his eye, and only after confirming that she had not made any attacking moves would he swallow his heart, which had been pounding in his throat.

Lin Ping made three different sized molds to make barbells of different specifications, because soldiers with different physiques couldn't be subjected to the same training.

Furthermore, archers primarily train arm strength, while cavalrymen primarily train strength in the waist, abdomen, and thighs, which is precisely the ancient emphasis on individualized instruction.

Considering the tight schedule, Lin Ping finally proposed a shift work arrangement, except that workers on the night shift would receive double their monthly pay.

These young workers were unaware of the hardships of shift work, and they were vying to work the night shift for such a small amount of money.

Left with no other choice, Lin Ping stipulated that two groups of people take turns working the night shift.

"Sigh...they're still so young." Lin Ping shook his head meaningfully, looking at the young workers with heartache, hoping they would still be young a month from now.

Because Lin Ping knew how hard the shift work was, he wouldn't mistreat these workers. Once the rock salt mine was fully profitable, he would give them three or even five times their monthly wages.

The wicked Lin Ping not only pioneered the shift work model, but also stipulated a system of double pay for overtime, which naturally made these workers, who were short of money, happy to work overtime.

"It's just a temporary measure..." Lin Ping secretly warned himself that he must never exploit the working people, that overtime work should be voluntary, and that he should be paid more.

"Husband, how do you know that this will motivate the workers?" Jiang Yunying asked, puzzled. Although these workers didn't like to slack off, they had never been this motivated before.

"This is called a management model. In addition to shift pay and overtime pay, there are performance appraisals and various incentive measures such as employee stock ownership." Lin Ping launched into another long explanation, almost leaving Jiang Yunying bewildered.

Although Jiang Yunying only half understood what she was hearing, she still concluded, "Husband, you are even more cunning than Su Hongxin..."

"Isn't cunning a compliment?" Lin Ping readily accepted Jiang Yunying's assessment, even jumping for joy, which only drew more disdain from her.

On this day, Lin Ping traveled back and forth between the training ground and the ceramic workshop, where he could steal glances at his beautiful wife, train his private army, and supervise the cement firing process.

After Lin Ping's various incentive policies, the workers in the ceramics workshop went all out and produced over a hundred barbells in just one day, and also stockpiled a large amount of materials used for calcining cement. It's expected that barbell production will double in the coming days.

The next day, Lin Ping did not go to the drill ground again, but climbed up the city wall and roughly calculated the amount of concrete used.

For five consecutive days, the ceramic workshop was in full swing with production, and finally completed the target of two thousand barbells.

However, the production at the ceramic workshop did not stop; on the contrary, they worked even harder because the amount of cement needed to build the parapet was enormous. In addition, some people had to be sent to the city wall to prepare the molds for pouring the cement in advance using wooden boards.

During this period, Lin Ping paid for everything out of his own pocket, with a huge amount spent on purchasing firewood.

This night was the first day of the fourth lunar month, the night of the new moon, and there were only a few scattered stars in the dark night sky.

"Ping'er, half a month has passed now, how is the salt sales?" The city lord rubbed his hands together, almost asking Lin Ping for money directly.

That's a treasure trove. Plus, the people of Jiangcheng are short of salt. In half a month, they could earn at least 50,000 taels of silver. According to the shares, the city lord's mansion could get nearly half of it. No wonder the city lord is so anxious.
