"What is the Prisoner's Dilemma?" Di Guanzhong and a group of officials were dumbfounded, waiting for her to say the following.

"I guess you should have a lot of information, go and deceive them."

"I tried, but it didn't work." Di Guanzhong said.

So I said that to take advantage of the "prisoner's dilemma", everyone has a rational side and will choose what is most beneficial to them. Luo Xiaoqiao said slowly.

"So what? What does Miss Luo mean? Di Guanzhong asked urgently.

"You put two people in solitary confinement and interrogated them and told them that if they both deny it, they will each be sentenced to a year in prison. If they all confess, they are exempted from capital punishment even if they are the principal offenders, and if they are not the principal offenders, they are sentenced to five years' imprisonment according to the law. If one person confesses and one denies it, then the confessed one is released, and the one who denies it is sentenced to death or five years according to the circumstances. ”

"This ...... Is that all it takes? Di Guanzhong couldn't believe it.

"Of course you can't do that, you have to use the information you get, trick them, and tell them the rules." Luo Xiaoqiao smiled and said, "You should be very good at interrogating prisoners, right?" ”

"Okay! I'll give it a try! Di Guanzhong said and walked away.

White Dog County was not far from here, and after he led the two of them for two hours, someone came over to thank them.

"Thank you, Miss Luo, thanks to your method, these two spoke. The adults are preparing to take them to the nest. It's a bounty of one hundred taels, and please laugh at it," said the officer, handing over a cloth bag.

Really?

There was a choking cough in the wind, and it was the shocked officials who were poured into their mouths by the cold wind.

……

Later in the evening, Luo Xiaoqiao's carriage left the place and headed south.

She checked the progress of the officials of the Ministry of Industry along the way, explained some precautions, and left quickly.

But even so, it took three months to walk down the three routes, and when I got home, it was already winter.

"You're back."

At the entrance of the village, you can see Grandma Luo standing under the big locust tree.

I don't know when her grandchildren will come back, but she's used to coming out every day to take a look.

When I saw the familiar carriage today, I immediately smiled.

"Grandma!"

Luo Niuniu rushed directly from the car and threw himself in front of the old man, almost knocking Grandma Luo to the ground.

"Okay, hold steady, tired, let's go, go home, go home and rest for a while."

Grandma Luo looked at the young man who was obviously a head taller, her face was a few points darker than when she left, and she was more strong, and she was immediately very relieved.

After a while, the small courtyard of the Luo family was crowded with people again.

Luo Jinrong heard that the people had returned, and he also brought the villagers over to take a look.

I haven't seen you for months, and it's really weird to miss it.

Shen Yinzhu also squeezed over from the crowd, holding a paper bag in his hand as if he was invited: "Sister Xiaoqiao, look, I made the powder you said!" ”

"What's the powder?" Luo Niuniu interjected and pinched the paper bag by the way: "It's black, what is it?" ”

"That's what Sister Xiao Qiao said, make some commonly used wind and cold medicinal materials into finished products, and put them in the pharmacy to sell them, and the minor diseases in the province also have to look at Langzhong."

"Okay", Luo Xiaoqiao said appreciatively, she casually mentioned it at the time, but she didn't expect Shen Yinzhu to be interested, and really let her study it.

"Have you tried the effect?"

This is a medicinal herb, so you can't just eat it.

"A while ago, there were a few people who fled from the famine, they should have come from the mainland to escape the war, and when they were sick for a while, they were willing to try, and it was really effective after eating."

"That's good, you look at the arrangement, isn't the medical hall handed over to you? Well done! ”

"Well, Sister Qiao."

As he was talking, Luo Erzhu walked in with a twist: "Xiao Qiao." ”

"Brother Erzhu, what's wrong?"

"That..."His blushing was a little unnatural, and Luo Xiaoqiao blinked, "What's wrong?" ”

"Poof", before she could ask, Shen Yinzhu's mouth was sluggish, and he said everything he wanted to say but didn't dare to say.

"Brother Erzhu has taken a fancy to Sister Meihua, so he went to propose to Aunt Bao, and Sister Meihua said that she had to agree to it."

"It's a good thing, when is it?" Luo Xiaoqiao asked.

As soon as these words came out, Luo Erzhu's face turned even redder, "Just, just a few months ago..."

"Oh... Plum blossoms are the pillars of my life, are you going to get married? So what if I don't agree? Luo Xiaoqiao deliberately teased him.

"No... Disagree?! Luo Erzhu raised his head at the time, his face full of disbelief.

"No, Xiao Qiao, we're also working in the workshop when we get married. It doesn't affect it, doesn't it? ”

Luo Erzhu was incoherent, and he almost knelt down and begged her, as if she was a bully who beat mandarin ducks.

Luo Xiaoqiao looked at his quail appearance and thought it was funny: "Okay, I won't tease you, as long as Meihua is willing and you are happy, I will not object." I'll talk to her later. ”

"Alas", Luo Erzhu agreed to go away.

In the afternoon, Luo Xiaoqiao went to Tianji Pavilion to take a look.

She left the drawings of the steam train before leaving, and there are enough people in Stone County, so I think there should be progress.

"The girl is here?" As soon as I entered the door, I saw Old Man Wang and others surrounding a big guy.

Luo Xiaoqiao's eyes lit up instantly: "So fast!" ”

"Girl, look at it!" The second elder and the third elder also gathered around, and in order to build this big guy, a group of them tossed a lot, which was really not as simple as building that artillery.

Luo Xiaoqiao walked around, his mouth full of surprise.

The steam train, which was completely different from the train she had ridden.

The most striking thing that catches the eye is the huge boiler and chimney, as well as the large and complex wheels and connecting rods on both sides.

Luo Xiaoqiao looked at it and nodded: "The progress is very fast." ”

"It's not okay, so I made a shell, and I have to study it in detail, and it just so happens that you are back and will study and study together."

"Cheng, I'll let Master Sun start work first, and then I'll come over." Luo Xiaoqiao walked out as he spoke.

The weather is really not warm, but the deserted village five miles south of Luojia Village is already crowded with people.

Luo Xiaoqiao didn't wait for the drawings of the Ministry of Engineering to come back, because this section from Xingcheng, there is no doubt that the plain area, there is no need to think too much, she directly chose the route that is most conducive to the entry and exit of her own goods, and laid it all the way to the south.

Master Sun had already returned with people, and the roadside was full of cement and stones, and even the tools for excavation were prepared.

"Princess, are you going to start work?" Master Sun's eyes were full of excitement, this is a big project, with this, he doesn't have to do anything else for a few years, and he is even the largest contractor in the North.

"Let's go!"

The drawings are available, the raw materials are also ready, and although there is still no special machinery, fortunately, the labor is very sufficient.

In addition to the locals, there have been many people from the mainland who have fled the famine recently.

Luo Xiaoqiao didn't let people give porridge, on the contrary, he used work for relief, and the people who came to do it were very dignified.

Luo Xiaoqiao only plans to open ten miles, from Luojia Village to Xingcheng by detour, which is enough.

Their movements are not small. At the beginning, officials of all sizes came to visit every day, and later found that they were digging pits, filling soil, and tidying up every day... These simple jobs, if nothing happens, they won't come.

A few months later, the railway was opened on an early morning when the sun was rising.

"Click, click..."

"Woo..."

The sound of trains moving and whistling came from outside the silent city walls, and was immediately heard by the early risers.

Many people nervously grabbed the weapons at hand, and some of them were already rushing towards the yamen.

"What's going on?" When Huang Yuzhang heard the news, he didn't even bother to put on his shoes, and rushed out of the house with his garbage.
