Li Feibai said: "Can you still get out after entering the Guozijian?" How did I hear that entering the Guozi Prison is equivalent to going to prison, unless there are special circumstances, it is impossible to get out at all! ”

Ma Zheng smiled and said: "That's after enrollment, it's not considered enrollment yet, you can come and go freely!" ”

I see!

Li Feibai nodded and happily agreed: "Okay!" He glanced at the other two beds in the room, which were covered but no one was seen, and said, "Otherwise, I'll invite you, and when those two people come back, let's go out and get drunk together!" Everyone sleeps in the same room, why not take this opportunity to make friends! ”

Ma Zheng waved his hand again and again, and said, "It's okay to wait for them to come back and go out together, but I must invite me for this meal, who called me older than you, it's your big brother?" If you are a big brother, you have to look like a big brother, how can you let your brother treat you, naturally the big brother will invite you! ”

Li Feibai saw that it was difficult to resist the hospitality, so he arched his hand and said: "It's better to be respectful than to obey your fate, this meal will be invited by Brother Ma, and I will be the east another day!" ”

Ma Zhengdao: "That's it!" After a pause, he scratched his head embarrassedly and said, "Brother, I have something I want to ask you for a favor!" ”

Li Feibai said: "Brother Ma, please tell me if you have something, don't be so polite!" ”

Ma Zheng muttered for a long time and said, "Yes...... That's the case, I don't have a lot of money, it's naturally enough to invite my brother to eat and drink, and there are two more people at once, but I'm afraid that it won't be enough when settling accounts, and then I will lose my adult. You, can you borrow a few dollars of silver from your brother, lest your brother make a big joke then! ”

After that, he patted his chest again and said, "Brother, don't worry, my brother is not a person who owes debts and does not pay back, and he will definitely pay you back in two days!" ”

Li Feibai cares about everything, but he doesn't care about money, he can't help it, he is rich and capricious. Without saying a word, he took out a silver ingot weighing ten taels from his arms, put it in Ma Zheng's hand, and said, "Brother just take it and use it, when it's not enough, squeak, I'll give it to my brother again." ”

Ma Zheng hurriedly refused, saying: "A few dollars of silver is fine, I don't need so much!" ”

Li Feibai smiled: "Make up a whole and pay off the debt!" ”

Ma Zheng thought about it, thanked him, and took the ingot of silver into his arms. He looked at Li Feibai and couldn't help but sigh, and said, "Brother, it's really a blessing for my old horse to know you in this life!" ”

It's no wonder that he feels this way, in order to be able to spend money to study in Guozijian over the years, he has suffered enough to borrow money, and has borrowed relatives and friends.

When he met relatives and friends who looked down on him, he borrowed ten taels of silver and sent him away for three or five taels of silver. When he met relatives and friends who looked down on him, even if he only borrowed three or five hundred yuan, they would send him away with a "no", or ask, in your situation, what will you pay back.

He has never met a relative or friend like Li Feibai, who borrowed a few coins of silver and took out ten taels of silver for you at once, and he was a friend he had just met, so he looked up to him too much.

Death for a confidant! Finally met such a cheerful friend, he couldn't be too stingy, got up and came to his bed, took out a tightly sealed wine jar from under the bed, handed it to Li Feibai and said: "Brother, when you meet for the first time, I don't have anything good to give you, so this thing should be regarded as a meeting gift for you!" ”

Li Feibai said: "Brother is too polite, as soon as we meet, I will give such a heavy gift, I can't find a return gift for a while, so I have to return it another day." What is this jar that my brother gave me, is it the wine brewed from your hometown? ”

Ma Zheng shook his head and said, "It's not wine!" Guess what it is? ”

Li Feibai even guessed a few things, vinegar, soy sauce, and kimchi!

Ma Zhengdao: "You open the thing and see if you have seen this thing!" ”

Li Feibai opened the mud seal on the top, uncovered the paper covering the altar, and put his nose to the mouth of the altar and sniffed it. It didn't matter if he smelled it, his face was ecstatic for a while, and he couldn't help but sniff it a few more times, and couldn't help asking: "Brother Ma, what is this, why does it smell strange!" ”

Ma Zheng smiled: "You can guess." ”

Li Feibai smelled the smell, which was between gasoline and diesel, and probably felt that it should be kerosene. But kerosene is the name of later generations, and it is definitely not called kerosene at this time, saying: "I can't guess!" Brother Ma, don't hang on me, tell me what this thing is! ”

Ma Zhengdao: "There is a place in my hometown where a black greasy thing gushes out of the ground every day, because it ignites when it encounters fire, so the villagers call it fire oil." We have a remote area, most of the poor people there, not to mention buying candles, even oil lamps can't afford to light them! When everyone saw that the oil could be burned, they wondered if they could replace candles or oil lamps.

So every house had oil in their house, and as soon as it got dark, they used oil lamps to light it. But the smoke of the oil is so great that it often makes people unbearable! I like to look at the oil when I have nothing to do, and I found that the smoke of the oil is large because there are too many impurities in it, and if there is a way to remove the impurities, the smoke of the oil will be much smaller.

So in my spare time, I consulted craftsmen to see how to remove impurities from the oil, and after unremitting efforts, I finally extracted such things from the oil! ”

Speaking of this, he took the jar from Li Feibai's hand, took a lamp that was burned black but had no oil inside, poured some oil into it, and then took a lamp twist and put it in the oil to light it.

By this time, it was already dark, and the oil lamps illuminated the room.

Ma Zheng was proud and said, "Brother Li, look at the oil lamp I refined, how bright is the candle and the previous oil lamp?" ”

Damn, didn't you say that our country is an oil-poor country? Why did Daming have oil gushing directly to the ground at this time! With oil, there is the equivalent of gasoline, diesel, kerosene, and chemical products such as plastics, and many projects that were previously unattainable can now be gradually realized.

Li Feibai suppressed his excitement and said, "It's much brighter than candles and previous oil lights!" ”

Ma Zhengdao: "The fumes emitted are much less than them!" ”

Li Feibai said: "It's not just a lot less, it's almost invisible!" ”

Ma Zhengdao: "In this way, Brother Li will not dislike my gift, and then he will not accept it!" ”

Li Feibai said: "What Brother Ma said, such a good thing, how could I not want it!" After that, he wanted to pat Ma Zheng on the shoulder and tell Ma Zheng that he was going to get rich!

Not to mention anything else, even if everything can't be done, it is difficult for Ma Zheng not to make a fortune if he can refine oil into kerosene alone.

What can kerosene do? At least it can be used as fuel for kerosene lamps, which is many times better than the fuel for candles or kerosene lamps made of animal fat. How many households in Daming and how many taels of oil do they need to consume every year, this alone makes an astronomical amount of money!

But after he patted Ma Zheng on the shoulder, he didn't say anything like getting rich.

Ma Zheng is now bent on taking the Jinshi examination, even if the gold and silver mountains are in front of him, Ma Zheng is not necessarily tempted, how can he give up the examination and make money with kerosene?

Besides, God knows how much oil Ma Zheng's hometown can produce in a year, if the output is too small, and not much kerosene can be refined every year, then the words of making a fortune and the like are not deceiving Ma Zheng.

Ma Zhengdao: "Brother Li, what do you want to say?" ”

Li Feibai looked at it left and right, and said, "It's so late, our two roommates haven't come back yet, I'm afraid that the two of them won't come back tonight." Brother Ma, why don't the two of us go out for dinner and drink, and go out for a drink with them another day! ”

Ma Zheng rubbed his stomach and said, "I've been hungry for a long time, let's go, let's go eat." ”
