　　Julian Calendar June 1627
　　Iceland's Sertiana Peninsula. This peninsula is more than ten kilometers south of ReykjavĂk, a large port city in Iceland. Because it is close to the port, 90% of the peninsula is also fertile land, so it covers an area of ​​hundreds of miles. The peninsula is full of small villages, which is considered to be an area with a relatively concentrated and large population of residents on Iceland.
　　The dark middle world is over. Now is the era of great navigation. The world is undergoing drastic changes, and the cultural beliefs of all countries are changing rapidly.
　　But Iceland is still a slow life, like a paradise, as if it had not become a land under the rule of the United Kingdom of Denmark, Norway in 1262.
　　The number of villages on the Sertian Peninsula has only increased by three in the past few centuries, and the population of each village is between about 30 and 50 or 60. The largest white hazel forest in Herut Village has only There were more than a hundred people. It was originally a large manor called Hrutstucky. Later, when there were more free people, it became a small village.
　　There is a fertile field on the north side of the peninsula. It is summer, and the wheat seedlings on these fields are beginning to form ears. Although it looks sparse, it is slightly shaken by the warm sea breeze, and it looks very gratifying.
　　Although Iceland has a warm sea breeze blowing from west to east, it is on the edge of the Arctic Circle after all. The warmth of the year is only from May to October, and the real crops are only in the second half of May. It's only September.
　　To the east of the large field is a small hill with some white hazel trees growing on it. This kind of tree is drought-tolerant trees that grow in the cold zone of Siberia. It is similar to shrubs and cannot grow very tall. The only advantage is that it can produce some rich in oil. And starchy nuts, this hazelnut is considered a cherished food that is a specialty of Iceland.
　　Under a white hazel tree, there is a teenage boy wearing white linen pants and a deerskin windbreaker. He has golden hair like golden silk, which is more beautiful in the sun.
　　In the deep eye sockets under the bushy eyebrows, there are a pair of piercing and big eyes. The blue eyes are as translucent as gems. The high bridge of the nose, thin lips and snow-white skin prove that this is a typical Nordic German, and it is also commonly known as a Wei Jingren.
　　The child's name is Olaf Hadarsson, the second son of Hadar, the leader of Harut Village in the White Hazel Grove. He is also the child with the most beautiful hair in his family and even in the village, so people also call Olaf blonde, or blonde. Olaf.
　　Olaf is only ten years old this year, but because he has had enough nutrition since he was a child and inherited his father's tall and burly genes, he has grown to a height of almost five feet, and he looks like an ordinary 14- or 15-year-old boy. Lang is up.
　　In this era when the height of European people is generally no more than 5 feet (152.4cm), the Germanic people in Scandinavia, Iceland, Denmark and other regions are considered to be the tallest. Nearly half of men are only 5.5 (165.1cm). ) Less than feet.
　　Olaf's father and uncle are both six feet and five inches tall, so they also have the nickname "big guy."
　　Olaf sits on a bare rock under the white hazel tree, holding a charcoal stick in his hand as a pen to write and draw on a wad of yellowed paper, sometimes he mutters something while writing. .
　　If someone could get close to Olaf and look at it, he would see that all the words he wrote on the paper were square and square. If someone who had been to the far east Daming to do business saw it, they might recognize it as similar. Yu Damingguo's text.
　　"In the year 1627, China was in the Ming Qi or Chongzhen period(?), and 1644 was the time when the Ming Dynasty fell.
　　It is understood that in this era, Daming is still the most powerful, wealthy and civilized country in the world. Now is the era of great voyages. The Middle Ages in Europe have long ended. The power of the Pope in Rome has been greatly reduced. The emergence of Protestantism, also called Christianity, has weakened theocratic power even more. For the control of the crown, Denmark and Iceland are now the Protestant Lutheran parishes.
　　However, Paris, one of the most developed regions in Europe, is still full of garbage, sewage is overflowing, and the water source is full of E. coli. It is a good place to live in the paradise of Iceland. There are no mosquitoes, cockroaches, insects, and the black death. It also has no relationship with Iceland. The environment is good. As long as you don't catch colds or more, you can live a long life. The only disadvantage is that life is too boring and material is extremely scarce. Question..."
　　This diary-like note came from Olaf, but Olaf is not an Icelander born with nothing.
　　Olaf has the memory of his previous life since he was born. He clearly knows that his previous life was the North Drift of Huaguo Yanjing. He has worked as a security guard, a tallyman, a salesman, and a CD-ROM. His only hobby is to like. Chinese and foreign history, but you can forget it when you read it, and you can't remember many real things.
　　After being reborn in Iceland, Olaf knew that he could only work hard to live his life. He started to learn Icelandic language and the living habits of Icelanders since he was a year old, so as to integrate himself into the life of Icelanders as soon as possible, and also from the inside. An Icelander.
　　Olaf is indeed very clever. He can speak at the age of one and a year and a half to form words. He can accurately express his needs in one sentence when he is less than two years old. This surprises his father Hadar and mother Catlin. , Their relatives and neighbors are also proud of it, after all, there is something rare in an area like Iceland that can be a treasure.
　　When Olaf was three years old, he could basically live independently-as long as the family had ready-made food.
　　After Olaf was two years old, he began to try to use the charcoal left over from the fire at home to record the historical knowledge and time points he had worked hard to think of about this era, as well as various technological technologies.
　　In the beginning, Olaf painted Chinese characters on the stone walls of his hut. Later, he found the old sheepskins at home to record. Only recently did he get rough but usable paper.
　　Olaf originally thought he was very good. He could remember the ratio of nitrate, sulfonate and charcoal and the processes of porcelain burning, wine making, vinegar brewing, and papermaking. Basic physics, basic chemistry and other knowledge can also silently write a lot of content.
But the problem is that he only knows the superficial procedures and basic content. To succeed in the operation, he may have to go through thousands of failures. Moreover, some experiments require specific tools. After understanding the backward social level in Iceland, Olaf does not Think again.
　　Therefore, Olaf's desire to use the advanced knowledge in his mind to develop an industry to get rich overnight has long been shattered.
　　Olaf now only writes down his conceivable knowledge and memories of current historical events, thinking that he can rely on prophetic foresight to make political speculations in the future, maybe he can reach the pinnacle of his life, and perhaps become famous in the history books. There are characters with surnames and stories, not the people of Iceland.
　　When Olaf discussed with his father last night about the only merchant ship in his family, he heard that his father said that the hull was eaten badly by ship maggots this year, and he had to spend a sum of money to buy wood repairs. Since the beginning of the spring this year, he earned more than half of the money he earned from two trips to England. On the ship repair.
　　Olaf didn't sleep well all night. He thought of the article about the management of ship maggots he had read in his previous life, and then ran out early in the morning to record the methods of treatment of ship maggots that he could use.
　　European sailors still use the most traditional method to prevent and control ship maggots, that is, using asphalt, glue, and tar to soak the wood, but after a long time in use, they still cannot prevent the emergence of ship maggots.
　　Olaf knows only three methods, One is to soak the wood with copper sulfate and then brush with tung oil. This effect is very good, but now you can't find copper sulfate in Iceland.
　　The second method is to coat the hull with copper or iron. This is also very effective, but the cost is extremely high. It is not a method that the current Olaf family can afford. Moreover, the current sailing technology and ships cannot withstand copper and iron. After the weight.
　　The last method is very simple, that is, the boat sails into the frozen freshwater river and uses the cold and fresh water to kill marine life such as boat maggots, but it takes more than three months to adopt this method. Generally speaking, No one's boat can be idle for so long.
　　But the last method is most suitable for Olaf's family.
　　Iceland produces nothing in winter, does not require production activities, continuous sub-zero temperature and occasional snow is not suitable for going out, which makes Icelandic people can only stay at home, eat, drink and sleep, and wait until the weather changes in the next spring. Only after warming did they start production and life, or went to be a pirate to grab a ticket, or drove a boat to do a few business trips, or worked in the fields.
　　Olaf felt that Hadar could drive the boat into the Shorso River before the arrival of this winter, and the boat maggots in the hull would be completely dead by next spring at the latest.
　　Feeling that this method was very good, Olaf solemnly put away his treasure book, and then walked out of the white hazel forest that was handed down from his family for more than two hundred years to the village to the east.
　　Note: The unit for measuring length in ancient Europe is the length of steps and feet. One inch or one inch is the width before the thumb joint. Later in the 13th century, King Edward II promulgated the "standard legal inch": from the middle of the barley ear Choose the three largest grains that are one inch long in a row head-to-head. Converted to millimeters, it is about 25.4mm. 12 inches is 1 foot.
