In the afternoon of the same day.

Gonggong Hai respectfully sent a few white stones with a glass luster to Li Chang'an.

"Lord Castle, are you talking about these things?"

Li Changan picked up a stone and looked at it, sniffed it again, and a smile appeared on his face, "Yes, this ore is called saltpeter, continue to send people to find it, the more the better." ”

Saltpeter, also known as flame nitrate and potassium saltpeter, the main components are potassium nitrate and sodium nitrate, which generally appear in salt lakes, saline-alkali soils, cave sediments, toilet soil walls and other places.

The reason why Li Changan can remember it so clearly is because he has read a lot of novels in his previous life and remembered one of its key uses - making ice!

While inspecting the city, he stumbled upon saltpeter in some corner corners, and the idea was immediately struck.

The perennial drought of the border city and the serious salinization of the soil are the environment where saltpeter is easy to grow.

Now that it's summer, the heat is unstoppable, there must be a market for selling ice, and the price will not be cheap, this matter is really a big profit.

If there is no money, it is simply impossible to develop a border city, and at this time, the city lord's mansion is poor and white, of course Li Changan has to find a way to make money.

Hai Gong said openly: "City Lord, I have inquired, such stones are quite common in the vicinity of border cities, and someone has found a large amount of saltpeter in a cave. ”

"Oh? That's great! ”

Li Changan's eyes lit up, with this kind of subordinate to do things, it is worry-free, not only to be able to carry out orders, but also to extend and exceed the quota, that cave may be a saltpeter mine!

A small amount of saltpeter can't be made into ice cubes at all, and Li Changan was originally worried about the quantity, but he didn't expect that this would be solved.

The surprise came too suddenly.

He immediately ordered: "Gonggong Hai, you have done a good job this time, immediately send someone over to investigate the situation, if it is really saltpeter, directly mobilize all the people of the City Lord's Mansion to mine it!" ”

"Wow!"

Although Gonggong Hai didn't know what saltpeter was, seeing that Li Changan was so excited, he naturally didn't dare to slack off, and immediately started to work hard.

However, he was just about to walk out of the room, but Li Changan stopped him again.

He asked meaningfully: "Father-in-law Hai, does my mother have something for you to keep on your behalf?" ”

Gonggong Hai's body was shocked, and he quickly knelt on his knees, and said in a trembling voice: "Lord City, this, this ......"

Seeing his reaction, Li Changan suddenly knew in his heart, and said calmly: "You tell the truth, I won't blame you." ”

Gonggong Hai didn't dare to hide it, so he could only nod and say: "Yes, the princess secretly handed over some jewelry to the old slave, the old slave didn't mean to hide it from the city lord, but the princess specially explained to the old slave before coming out, and I can't let you know that there are these things until the last resort." ”

The jewelry given by the princess is used to give Li Chang's life, if he really can't survive, he can exchange it for money to survive the disaster, because the three princes are unbearable, and if he knows that these things exist, there is a high probability that they will be lost quickly, so this is why Gonggong Hai concealed it, and by the way, let the three princes suffer a little in the border city to see if they can grow.

It's really well-intentioned.

Gonggong Hai was shocked in his heart, he didn't expect Li Changan to be able to guess the princess's backhand, he found that the third prince had not only changed, but also became much smarter, which was both relieved and awe-inspiring.

Li Changan can think of these things because he feels the maternal love from the bottom of his heart, his mother will never watch him suffer, and the things he wants to leave behind are still valuable, and the truth is as he thought.

He had some warm feelings in his heart, and said after a moment of silence: "You exchange these things for food, post a notice, and say that the City Lord's Mansion will give porridge for half a month from tomorrow, once a day in the morning and once in the evening." ”

"No, no!"

Gonggong Hai's voice was earnest, and he kept kowtowing, "Lord of the city, these are the princess's life-savings, you can't do it for those cheap ...... Civilians don't care about themselves, and the old slave begs the city lord to take back his life. ”

Li Changan couldn't explain, so he said directly: "Don't worry, I know it in my heart, you just do what I say." ”

Gonggong Hai heard Li Changan's determination and knew that persuasion was useless, so he could only retreat unwillingly.

"System, bring up the Properties panel."

"Name: Li Chang'an."

"Realm: Ordinary."

"The city: a city on the border."

"People's Heart: -1989."

Li Changan smiled slightly, the people's hearts finally changed from minus 2 to minus 1, it seems that the last horse-drawn carriage burning incident fermented well.

The reason why he chose soup soup is because his time is very tight, and in order to make the people's hearts return to zero within half a month, he must use heavy means and the results must be fast.

As long as the system is completely bound, then everything paid is worth it, but if he can't pass the novice test, Li Changan will really be blind.

After a while, An Zhaoran ran in in a hurry and asked directly: "Li Changan, do you really want to exchange the things left by your godmother for food porridge?" Are you crazy?! ”

You don't have to think about it to know that it must have been told by Gonggong Hai, Li Changan had a headache and said, "That's the case, but I'm not crazy." ”

An Zhaoran said angrily: "Then let me ask you, you have spent all the money left by your godmother, what will you take to ask for guards in the city lord's mansion in the future, what should you do if you eat by yourself?" ”

Li Changan said: "I have already thought of a way to make money, don't worry." ”

An Zhaoran didn't believe this sentence a hundred times.

Li Changan has only spent money indiscriminately since he was born, and he has never earned a penny at all, and he has a fart way to make money, and eighty percent of it is whimsical.

She persuaded: "How can it be so simple to make money, don't be too naïve, I know you have become better, but if you want to do things for civilians, it's not like this, we have to take our time and think in the long run." ”

It seems that her personality has been successfully reversed, and this girl has already used 'getting better' to describe herself.

And this girl is so anxious, obviously she cares about me.

Li Changan smiled and said, "Zhaoran, why don't we make a bet?" ”

An Zhaoran was stunned, "Bet? What to bet on? ”

"Just bet on whether I can find a way to make money in half a month, if I win, you can call me brother, if I lose, I will listen to you in the future."

An Zhaoran's eyes rolled and he hummed arrogantly: "Okay, that's what you said." ”

She felt that she had won, as long as Li Changan listened to her in the future, she could accept the loss of something.

……

A moment later, a guard walked out of the city lord's mansion and posted a notice on the notice board, and many civilians immediately surrounded him.

"The City Lord's Mansion has posted a notice again, and it won't be re-taxed, right?"

"It's over, it's definitely targeting us civilians again, I know that the third prince won't change his sex so easily."

"Anyone who knows how to read, hurry up and read it to everyone."

Soon, an old man came to the front of the line, he was a rare literate person in the border city, and he was also a teacher, who usually taught children to read and write for free, and was highly respected.

He looked at the notice, word by word, and immediately his eyes widened and his body shook.

"Elder Zhang, what is written on this? Explain it quickly. ”

"Oh no, looking at Zhang Lao's appearance, it must be a very terrible thing, and his reaction to the notice last time was not so big."

"The third prince is lustful, is he going to rob the people's daughter?"

Suddenly, Zhang Mingda glared angrily at the people who spoke, and said loudly: "Shut up, I don't allow you to slander the respected city lord!" ”
