Back to the thatched cottage, except for the guards who were on guard at night, everyone else went back to the house to rest, and the corner towers surrounding the house in the distance were lit with lights.

In particular, the corner tower near the river bank is built high and steep, the top pillar is topped, the four walls are empty, an oil lamp is as big as an iron pot, and the wick of three strands as thick as a baby's arm is also lit, and the glass cover is used to block the wind, looking from afar, it is bright and just like a bright moon hanging on the corner of the house.

If there is an attack on the camp nearby, or if a night boat docks, the lantern keeper on the corner tower will also use a large bronze mirror with a concave surface to focus the light farther away.

Standing in front of the thatched hall, Liu Yue'er embarrassedly pulled out her hand and asked Lin Lian: "Are you hungry, I rubbed the rice balls and cooked them for you?" ”

"Hmm." Lin Jian nodded, and looked at the lights on the corner tower in the distance, which were as bright as the moon.

The light of this corner tower was originally the idea of Ge Siyu's father, the old engineer Ge Fu, the secretary of the Jiangning Ministry of Industry, and when he drew the pattern, Lin Jian instantly thought that if there was a lighthouse in the world, it should be like this.

After chatting with Ge Fu, I learned that in some ports and some steep gorges along the coast of East Fujian and Liangguang, there were maritime merchants or fishermen who raised funds to build lighthouses. If you can't afford to use lamp oil, you will accumulate salary to light the fire, but the actual light intensity and distance are limited, and the role of the lighthouse in night navigation is not obvious, so the lighthouse came out earlier, but it is not popular.

Ge Fu made some improvements on the basis of the existing lighthouse, and the structure of the giant oil lamp was similar to the kerosene lamp in Lin Bin's memory, except that the oil storage lamp holder was made of copper, and the lampshade for sheltering the wind was a glass cover, and a large bronze mirror was used on one side to reflect the light, increasing the directional light intensity and distance. However, the original pattern that Ge Fu showed Lin Lian was that the large bronze mirror was a flat mirror, and Lin Jian proposed to make a large concave bronze mirror instead, and specially made a wooden frame for the concave bronze mirror that could be moved and adjusted in angle.

When the world's craftsmen already knew that the concave mirror had a concentrating effect, Lin Lian's words were a little clear, Ge Fu exclaimed, feeling that Lin Lian's small improvement was wonderful, and said that Lin Lian was definitely a first-class master and craftsman if he wanted to enter the general's work, and he couldn't persuade Lin Lian to enter his door. Lin Jian was very ashamed in his heart, and he could be regarded as working together to drum up a relatively perfect lighthouse plan.

The glaze craftsman of the Jiangning Ministry of Industry can burn the glass to be almost transparent like glass, but the cost is too high, and the glass cover used in the lighthouse is the face of Ge Fu and Ge Siyu father and son, and the glaze workshop of the Jiangning Ministry of Industry also collected one hundred and twenty taels of silver from Jiyun Society, which is enough to buy fifteen acres of fertile land in Jiangning; The large concave bronze mirror was polished by several mirror masters in Jiangning for nearly a month, completely relying on experience, and also spent thirty taels of silver. This is still secondly, to maintain a certain brightness, it is nothing more than the use of multi-strand wicks with better oil immersion, which naturally consumes more oil. At that time, lamp oil was mixed with cooking oil, and it was slightly more expensive than pork, and the huge oil lamp in this corner tower alone cost one or two taels of silver to burn oil every night, which was enough to hire forty or fifty middle-aged laborers.

Limited by the light source and reflective materials, the long-distance illumination distance of the lighthouse is naturally far from being comparable with the searchlights of later generations, but it can barely illuminate the distant prison island pier, with a light distance of almost 500 steps, which is already satisfactory in the current world.

While improving the safety of the camp, the lights of the corner tower also make it possible to start construction at night above and below the embankment. Since Jiyun Society only had the financial resources to build a berth by the river at this time, the construction area was limited, and it was impossible to increase labor indefinitely, so it was precisely shift work that greatly improved the work efficiency.

Looking at the lights of the corner tower in the distance, Lin Jian knew that the money was worth it: not only at this time, but also after the dock stack was completed. The lighthouse can guide the channel and guide the ship into the harbor for the night boat; Provide night lighting for the wharf, make it possible to load and unload goods without interruption day and night, and improve the efficiency of berth use; It can also curb the sneak attacks of river bandits and bandits at night; Although the effective light distance is limited, the corner tower lights on the river bank can still be clearly seen from the north bank of Chaotiandang, and it can be used as a beacon for communication at critical moments.

Lin Jian returned to the house, Liu Yue'er had already helped him light the copper oil lamp in the house before cooking the rice balls, and the oil lamp burned soybean oil, and the room was filled with a faint smell of grease.

This copper lamp is also made by the old engineer Ge Fu, and has a ring-shaped copper cover that can be opened and closed at an angle, the copper cover can be shaded from the wind, the inside is polished, and the directional light can be increased, and the thin copper pipe will guide the ignited smoke back into the water tray under the base. This copper lamp costs six catties and four taels of copper, not counting the workmanship and also folds one tael of silver, naturally it is not something that ordinary people can use, but it is much more economical than using a copper glazed cover oil lamp, and it is also more delicate and practical. Lin Jian took the slightly hot copper oil lamp in his hand and looked at it, thinking to himself: The wisdom of the world's skilled craftsmen should not be despised by future generations.

"What are you thinking?" Liu Yue'er brought the boiled rice balls, held the copper oil lamp in a daze for no reason, and asked curiously.

"The intelligence of the people of the time is impressive." Lin Jian put the copper oil lamp on the case.

"Inexplicable emotion, when is there no stupid person and no smart person?" Liu Yue'er smiled and was about to leave with the tray.

"Talk to me." Lin Jian called out to her.

"......" Liu Yue'er hesitated for a moment, then said with a red face, "You really can't bully people." Holding the bookcase in his hand, he sat down opposite Lin Tie.

Lin Jian looked at Liu Yue'er's crimson and charming face under the lamp, and his heart fluttered, if she hadn't said so, she would have talked to her seriously; Hearing her say this, I immediately took her soft little hand and put it in the palm of my hand to caress it carefully, feeling the tenderness and delicacy of the heart.

Liu Yue'er was really embarrassed, and she didn't pull out her hand, so she rested on the desk with one hand, her face lying on her arm, and her eyes looked up at Lin Tie under the lamp, and she felt very sweet in her heart, but she was afraid that Lin Tie would make further requests. On the one hand, although she said that she was rushing back to her mother's house, her husband's family also had some power in Shiliang County, and she was following someone for no reason, and the Xiao family was going to make trouble, and there might be big trouble. On the other hand, after all these years, of course, there is no reason to despise herself, Lin Jian wants to give her an official title, Liu Yue'er has long thought about it in her heart, and she will not count the name of the concubine, but she can't be unclear. It's just that Lin Lian is tied to prison island and estuary these days, and she has no time to think about other things, and besides, Liu Yue'er herself can't take the initiative or hint at anything, she always feels that it will despise herself.

"You sit down ......" Lin Jian looked at Liu Yue'er's face lying on the desk looking delicate and abnormal, the transparent white and tender slightly crimson, looking delicate and delicate, the hair was like a crow, the ears, the bridge of the nose, the red mouth and the long eyelashes were all beautiful under the lamp, and they all said that the beauty was the most intoxicating wine, just staring at it, I felt a little intoxicated. Lin Jian didn't deceive the dark room, but he couldn't help it, took Liu Yue'er's hand, and wanted her to sit in his arms.

"......" Liu Yue'er's eyes were as clear as a spring, and her eyes flowed, but she gently wanted to pull it back, and said softly in her mouth, "Yue'er should go back and rest." In the dead of night, when the moon was alone, she also wanted to hold Lin Tie in her arms, but of course she was afraid that she would not be able to clean it up if she connived at Lin Tie.

Lin Tie can read the desire and rejection in Liu Yue'er's eyes, and can also understand the fear of the woman in the world about the leakage of the festival to outsiders, but the impulse of lust is a moment of refreshment, but the woman falls into extreme worry and fear of pregnancy in the next month, Lin Tie will not do such a thing, but I am afraid that explaining to Liu Yue'er at this time The so-called safe period will not work, grabbed her hand, and said: "I also see the state of the female prisoner on the island; I won't hurt you, but I can't take the time to go to Shiliang right now......"

Nine out of ten of the female prisoners held on the island are imprisoned for the crime of adultery, and the former prison, the secretary and others forced the female prisoners to sell themselves in the brothel of Quyang Town, which was a felony spurned by everyone in later generations, but it was a misdemeanor that could be atonemented by copper, and even many people stood up to defend them, even Chen Xiyan such a great Confucian in the world also openly declared that women who committed adultery should be filled into a brothel to atone for their crimes, which shows the attitude of the world towards women who commit adultery and adultery, and some local villagers in Chongzhou County even raised funds to build Jieyi Hall, Widows were grouped in the territory to prevent widows from losing their manners.

Hearing Lin Tie say this, Liu Yue'er still said softly uneasily: "You really can't hurt me......" sat side by side with Lin Tie with a crimson face, Lin Tie took advantage of the situation and pulled her into his arms, Liu Yue'er supported Lin Tie's thick chest and struggled a little, but sat on his thigh, holding a wooden peg like a thing, his pink face was as red as drunk, and he immediately curled up quietly in Lin Tie's arms, no longer struggling or saying anything.

The spring night after the sting, the weather is not very cold, all change into spring shirts, hug the beauty into their arms, you can clearly feel the soft elasticity of the delicate body into the arms and the warm body temperature, Lin Tie is still a first brother in the world, but it is not that he does not understand the things of men and women, looking at the shyness and affection on Liu Yueer's face, and more and more I feel that the beauty in my arms is delicate and uncontrollable, her face is attached to her smooth hair like a crow, and she feels the rare tenderness of this late night, just like the undercurrent of the spring stream, the moonlit night is hazy, and the love of germination \/ Lust is not an unstoppable beast.

Although Liu Yue'er felt that there was something like a wooden peg sitting under her arm, she was ashamed, and her heart was numb, but after sitting for a while, she waited for the irrepressible emotion to ease down, so she felt more sweet and comfortable, and she was not worried that Lin Lian would lose her reputation by inch, she raised her head in Lin Lian's arms, connected with his eyes, and said: "You haven't eaten the rice balls yet...... picked up the porcelain bowl, took the spoon and scooped the crystal rice balls into Lin Bin's mouth, Lin Jian asked her to eat it too, and she also ate two grains.

In the second half of the night, the moon in the sky was hidden by the clouds, but the lights of the corner tower were still like a full moon hanging above the treetops from the window to the light, Liu Yue'er sat in Lin Tie's arms and whispered: "The lights of the corner tower are really good, and the poor people can't afford lamp oil to work and study at night......

Lin Jian thought to himself: One or two lamp oils are worth more than half a catty of rice, and it is really not a lot of ordinary people who can be willing to use it.
