Su Jinxi looked at Li Shan, who was still busy in the small house in the backyard, and said, "Xianggong, take a break, and then get it later, it's time for lunch." Li Shan wiped his sweat when he did it, but he smeared the charcoal ash on his face, Su Jinxi looked at it and giggled, and said, "Xianggong has become a flower-faced cat." As he spoke, the handkerchief was dipped in water and wiped Li Shan's face.

It has been four days since Li Shan came back from Songzi, and Li Shan has not been idle in the past few days, he is doing a big thing, or a very important invention. This was the idea that was sparked at the time of Songzi quarrying, gunpowder. Gunpowder is one of the four great inventions of ancient China, and this thing has cross-era significance. So Li Shan has been fiddling with these things for the past few days. As a professional science student, Li Shan is very clear about the formula of gunpowder, which is sulfur, saltpeter and charcoal. But the ratio of ingredients is very critical, Li Shan has been looking for the best ratio, but it has not succeeded yet, but Li Shan is not in a hurry, I believe that after a few more attempts, everything will be clear. Of course, it's not just gunpowder, there's something else.

Li Shan took off his coat and threw it aside and said, "It's good to have someone to serve you, you don't have to wash your face yourself." Su Jinxi looked curiously at the bottles and cans in Li Shan's house and said, "Xianggong, what are you doing?" I see that you didn't read books after you came back from Songzi, and you didn't go out to find Sun Helian and them, so you kept your head bored in this hut. Li Shan smiled mysteriously and said: "This is a very powerful thing, the secret recipe I found in an ancient book, if it is successfully developed, it has the power of opening mountains and cracking stones." Su Jinxi smiled and pursed her nose and said, "Hmph, who believes what you said, I haven't seen you read a book twice all day, as the ancients said." ”

Li Shan shook her head helplessly, it seems that she has been spoiled during this time, and she dares to say this about your husband, Li Shan hugged Su Jinxi and said: "Little girl, dare to say that you are a father-in-law, see how I clean you up." The itchy flesh on Su Jinxi's waist was sneak attacked by Li Shan, and she quickly ran away with a smile, saying, "Don't make trouble, isn't it possible for the little woman to surrender." The little woman made amends to her husband. But looking at her bright eyes, there was clearly no fear at all.

Li Shan came over and hugged Su Jinxi and said, "Okay, little girl." I have something to do in a while, so you can go and play with Ruyan and Sun Ping. After lunch, Li Shan hurried to Lu Tingshi's mansion, Lu Jiuyuan had been waiting for Li Shan for a long time, and when he saw Li Shan coming, he smiled and said: "Haha, the virtuous nephew came very early, come in and sit." ”

Why is Lu Jiuyuan so enthusiastic? Or because of one of Li Shan's "inventions", Li Shan found out that Lord Lu turned out to be short-sighted, so after Li Shan came back from Songzi, he specially made a magnifying glass for Lord Lu, and the magnifying glass was relatively simple. It is enough to find a thick piece of glass and polish it a little, but fortunately, glass has been introduced to China from the West during the Tang Dynasty, but people do not know the benefits of glass. Of course, this magnifying glass was just a decoy, and Li Shan told Lu Jiuyuan that he had also invented a telescope that could see things miles away, which could be said to be a real clairvoyant. Lu Jiuyuan was naturally very curious, so Li Shan came to give him a treasure today.

After entering the house and sitting down, Lu Jiuyuan hurriedly said, "Virtuous nephew, is that telescope ready?" The magnifying glass you made last time was so easy to use, and now I have a lot easier to read official documents with it, and I don't have to lie on the table anymore to read it. Li Shan took out a tube from his cuff and said, "You see this is a telescope, but there is still a brother behind the lenses, I have already asked people to polish this lens, and I can send it over in a while." Lu Jiuyuan took the tube in Li Shan's hand, pulled it and pulled out a thin tube from the tube, and then looked up and down, there was already a lens on the side of the small mouth, and the side of the big mouth was still empty, and fiddled: "Virtuous nephew, are you saying that just such a thing can make people see things miles away?" ”

Li Shan said with a smile: "If my uncle doesn't believe it, my little nephew is willing to make a bet with my uncle." Lu Jiuyuan said: "Oh, let's hear it." Li Shan said: "Add this lens in a while, I bet that my uncle can directly look at the things on the Changhu Lake from your Lu Mansion, if you can't see it, I will lose." Lu Jiuyuan smiled and said: "Okay, if this thing is really as magical as you say, the old man is willing to gamble and lose, you can say something." Li Shan said: "Hehe, this is a little embarrassing." Li Shan whispered a few words in Lu Jiuyuan's ear, Lu Jiuyuan looked at Li Shan with a strange expression, and suddenly laughed and said: "You kid, you actually let me be, okay, the old man can be regarded as an adult." You, you, there really is yours. ”

As he was drinking tea, he saw that Zhao Long was led in by someone from the Lu Mansion, and Li Shan smiled: "The lenses are here." After speaking, he got up and took out the lens from Zhao Long's hand, pressed it on the telescope, and said, "Uncle Lu, let's try it quickly." Lu Jiuyuan was also a little impatient, and said, "Okay, let's try it." ”

Naturally, there is nothing to see in the Lu Mansion, all around is in the compound, and you can't see anything out of the wall, Li Shan said: "Why don't we go to the city gate to experiment." "The ancient city gate can be said to be the tallest building, of course Lu Jiuyuan agreed to this proposal, and quickly asked the housekeeper to pull the carriage and ran all the way to the north gate. When he arrived at the city tower, Li Shan taught Lu Jiuyuan how to use the telescope, Lu Jiuyuan dragged the telescope with both hands, opened one eye and closed the other, and said in surprise: "Hey, you can really see so far, you can see it clearly on the other side of the Long Lake, and the fishing boats in this water are clearly visible." ”

Just as he was happy, Lu Jiuyuan suddenly stopped talking, stared at the telescope carefully for a while, and said, "There seems to be an accident over there, let's go and take a look." The corners of Li Shan's mouth raised slightly, and the fish were finally hooked, and then asked, "What's going on over there?" Lu Jiuyuan said with a solemn expression: "It seems that someone is gathering to make trouble, and there are guys on both sides, I'm afraid that there will be a fight, Lu Laoliu, you don't care about the carriage first, hurry up to the yamen to call someone, and rush to the side of Changhu." ”

Speaking of Changhu's side, that's right, it is the Cai family and Zhuo Cheng who have already been on the bar. Of course, all this was arranged by Li Shan in advance, including Zhao Long to deliver the lenses, which is a signal, indicating that it has already begun. Cai Xiang was followed by more than 30 people, each with a knife in his hand, and said to Zhuo Cheng: "It turns out that your kid has always been fighting against my Cai family, and you have been beating everyone in our Cai family recently, right?" Zhuo Cheng said: "Bah, just a group of beasts like you, who specialize in doing things that hurt heaven and reason, we are doing the right thing for heaven at this time." Cai Xiang obviously didn't take Zhuo Cheng seriously, and smiled contemptuously: "How much more waves do you want to make as a little cub?" I tell you, today I will make this little bastard as an example, lest you fishermen make trouble for me every day. The one who wants to die with him should come. ”

Zhuo Cheng and the others were naturally prepared, and in an instant, twenty or thirty people stood up, and they all mentioned this guy in their hands, Zhuo Cheng said: "Don't think that we are still as easy to bully as before, just one of you Cai family is like making waves, let me tell you, no way, today is the day of the fall of your Cai family." ”

Cai Jing walked out from behind Cai Xiang and said, "Zhuo Cheng, I said why are you so ignorant?" Originally, your sister and I have become a good thing, you are my brother-in-law, we are both married, but you just have a tendon, and you still want to overturn our Cai family, I think you are looking for death. After speaking, his eyes showed a fierce light, and he was about to go up and cut Zhuo Cheng with a knife. Cai Xiang grabbed Cai Jing and said: "Don't be impulsive, they have a lot of manpower, we don't need to fight with them, I have already called someone to inform your uncle, and your uncle will come with an official messenger in a while." When the time comes, we don't need to do it, someone will naturally clean them up.
