"Your Majesty, in fact, in order to keep their blood pure, the Silla royal family often messed up*, and marrying an uncle was a common phenomenon in the Silla royal family at that time. Deman's great-grandfather, King Zhenxing, was the son of King Faxing's younger brother, King Lizong Gewen, and King Faxing's daughter, Mrs. Zhijiong. His grandfather, Prince Tonglun, married his aunt, Mrs. Wanhu, and gave birth to King Zhenping. King Shinpei also married Lady Maya, the daughter of King Fukusheng Kabun, who was regarded as the younger brother of Prince Tongwa, and gave birth to Deman. In fact, this means in our Central Plains that it offends God, so in the generation of King Zhenping, the Holy Bone Man is exhausted, which is God's punishment for the Silla royal family! Li Zhiyuan explained to Li Jiancheng and said flatteringly, in fact, this kind of thing, even in later generations of China, known as the Celestial Empire with the most perfect system and Europe, the cradle of world civilization, the marriage of close relatives is a common fact. The Habsburgs were the largest family in Europe, ruling Austria for six centuries and ruling Bohemia, Hungary and Spain by marriage. The family frequently intermarried in order to maintain hereditary power. During the 200 years he ruled Spain, there were 11 marriages, 9 of which were consanguineous marriages. Carlos II was born from the marriage of an uncle to a niece. Philip IV's grandfather, Philip III, was born to Philip II in marriage to his niece Anna. Habsburg children have a high mortality rate in early childhood and adolescence, with 40 per cent of infants not living to be one year old and half of children not living to be 10 years old. At that time, the survival rate of civilian young children in Spain was more than 80 per cent. In particular, the illness of Carlos II of the Habsburg royal family was clearly the result of consanguineous marriage. According to records from the time, he was short, weak, and suffered from intestinal diseases and uremia. He couldn't speak at the age of 4 or walk at the age of 8, and his debilitating symptoms had something in common with those of a child born of a close marriage. There was also the Great War I, when the war between Britain and Germany was a fight between Queen Victoria's grandson and grandson. However, the biggest feature of consanguineous marriage is that the inferiority factors of each generation will accumulate. Charles II's impotence and infertility were caused by a genetic combination of pituitary hormone deficiency and ureteral hernia, and the atrophy of the kidneys caused acid gas to be unable to be excreted in the urine. He had no children and died at the age of 38. In later generations, there were only the descendants of today's Tibetans, Tibetans - because in Tibetan culture, if there is a marriage between close relatives, there will be disasters such as snowstorms and earthquakes. Thinking of this, Li Jiancheng strengthened his determination to come to Silla and push Jindeman to the place, "When the time comes, Jindeman will be lonely and miserable." It's time for Silla, far away from his mother's homeland, to return to the Central Plains. ’

"King Xiaoyi, what you said is clear! You go and rest first, I have my own plans! "Yi Jiancheng strengthened his determination to annex Goguryeo, Silla, and Baekje. Immediately afterwards, he immediately met with the leader of the Tata tribe, the beggar Zhongxiang.

"The Great Leader of the Beggars!"

"His Majesty the Emperor of the Tang Dynasty!" Hearing the tone of the big leader of the beggar Zhongxiang, Li Jiancheng nodded in his heart - it is indeed the same as what Song Lingwen said, the beggar Zhongxiang is a very ambitious person, and he must have sustenance in his heart, so he dares to speak to himself like this. Li Jiancheng secretly said to himself - hum! Stinky boy, when it's time for a war, I must let you rush to the forefront, if you want to break away from independence, there is no way. Li Jiancheng smiled:

"The beggar elephant chief, I heard that you just gave birth to a son, I don't know if you have a name?"

"Thank you Emperor Li Tang for your concern, I have indeed just given birth to a son, and I have also given a name! ……”

"Oh! Is it! I don't know what the name of the great leader of the beggar elephant was! ”

"Ahh What kind of tree are we barbarians in the mountains and old forests named after! Grass! Cow! Sheep or something, it's hard to get to the hall of elegance! Although the beggar Zhongxiang has also been in the deep mountains and forests for a long time, he has also dealt with the businessmen and personnel in the Central Plains, and knows that the name he gave his son is a bit taboo in the Central Plains, so he didn't say anything more.

"Ahh Great Chieftain of the Beggars, I have heard that you have always wanted to establish a country of your own, and you want to trade with us Li Tang on an equal footing. I'm right! Li Jiancheng's words couldn't be heard whether he was happy or unhappy, but the beggar Zhongxiang still didn't answer positively, just treated Li Jiancheng with silence, and Li Jiancheng nodded secretly - this person cannot be underestimated, it must be eradicated. Otherwise, once it becomes a climate, it will inevitably be a big disaster for our country.

"The great leader of the beggar elephant really doesn't see rabbits and don't scatter eagles! I see, okay! I have decided that when I want to conquer Goguryeo, I will definitely form an alliance with the great chief, and I will go to the south, and the great leader will attack from the north and south, and when the time comes, all the lands of Goguryeo will be increased by me and the great chief, and one and a half will be added! ”

"Your Majesty, this is true!"

"I am willing to write an edict to the Great Chief, if one day, I will crusade against other countries with the Great Chief, then whoever captures the land will be his. However, if the Great Leader is acting alone, I will not be involved. ”

"Your Majesty is really a quick talker, I beg Zhong Xiang to thank you here. If Your Majesty has nothing else to do, he will go back first. If there is anything, Your Majesty can have someone go to me. ”

"Great Chief, please!" After the beggar Zhongxiang leader left, Li Jiancheng's smile immediately ended. When Li Jiancheng secretly met with Li Zhiyuan and the beggar Zhongxiang, he immediately summoned Li Chengdao, the king of Hengshan, Li Chenglu, the king of Hengyang, Xiao Yu, Feng Deyi, Wang Gui, the provincial servant, Wei Zheng, the imperial historian, the secretary Cen Wenwen, the commander of the Qilin secret guard Di Renjie, and the new Ma Zhou and Liu Bo. and Su Dingfang, Xue Rengui, Pei Xingjian, and civil and military officials in Youzhou.

"Ladies and gentlemen, I won't say much about what I came to this Youzhou for! In a word, I just want to know that the soldiers and horses requisitioned from all over the country have been fully mobilized, and the ordnance, grain and grass drawn from all over the country are sufficient! Youzhou Thorn Shi Ma Ming rose up and said to Li Jiancheng:

"Your Majesty, since receiving His Majesty's secret decree, the minister has led his bureaucrats and subordinates to prepare barracks for the placement of soldiers and horses from all walks of life, and now, the border troops transferred from all over the country have reached 120,000, and there are more than 80,000 war horses, plus the people and livestock who transport grain and grass, the population has reached 200,000, and the livestock has exceeded 100,000, but Your Majesty can rest assured, everything has been arranged, and the salt, grain and grass, and ordnance transported from all over the country are enough for the entire Northern Expedition army for two years." Di Renjie added:

"Your Majesty! For example, today's merchants heard that His Majesty would have a fight, and they have gathered in Youzhou, but the Qilin Secret Guard has already greeted them secretly, and asked them not to contact outsiders after they come to Youzhou, all of them are under the protection and control of the Qilin Secret Guard. Moreover, the patriarchs of the Zhang clan and the Qilu Heng clan in Jiangnan also secretly said that in addition to helping His Majesty transport supplies, they can also use their connections to contact a large number of merchant ships to transport sailors for His Majesty and land from Silla! Li Jiancheng nodded, but he was very sad - in fact, for China, the warship culture is very profound, and during the Spring and Autumn Period and the Warring States Period, there was a special shipbuilding workshop in southern China - the Boat Palace. Ships were often used to travel between vassal states, and there are records of warships. Warships were developed from civilian ships, but warships had to be equipped with both offensive means and defense against enemy attacks, so they had higher requirements than civilian ships in terms of structure and performance. It can be said that warships represent the highest shipbuilding capacity and technical level in various periods, and also reflect the economic power and production technology level at that time from one side. The warships of the Wu Navy were the most famous at that time, including various ships such as "艅艎 [yúhuáng Yu Huang]", "Three Wings", "Sudden Attack", "Lou Boat", and "Bridge Boat [Chuán Boat]". Also written as "Yu Huang", it is a large warship on which the prince rides, and serves as the command flagship in wartime. According to ancient records, the bow of the ship is painted with the pattern of a bird of the crane [yì益], which has excellent sailing performance. The main warships of the navy are the three wings, namely the large wing, the middle wing, and the small wing. Among them, the large wing is 10 zhang long and 1.5 zhang wide, which can carry more than 90 soldiers and soldiers, and has a high sailing speed. It was with these warships that Wu defeated Chu and Yue in the Han River and Taihu Lake. Later, Gou Jian tried his courage, and the warships of the Yue Kingdom when he destroyed Wu had grown to as many as 300.

During the Qin and Han dynasties, the development of China's shipbuilding industry appeared at its first peak. Qin Shi Huang organized a large fleet of ships capable of transporting 500,000 stone of grain during the war to unify southern China. According to ancient records, Qin Shi Huang once sent a general to lead a fleet of ships to attack the state of Chu. After the unification of China, he made several large-scale cruises, cruising on inland rivers or sailing on the sea. By the time of the Han Dynasty, the sailors with Lou Chuan as the main force were already very powerful. It is said that after a campaign, the central government of the Han Dynasty was able to dispatch more than 2,000 ships and 200,000 sailors. The fleet is equipped with a variety of combat ships, including the assault ship "Xiandeng" at the forefront of the fleet, the narrow warship "Mengchong" used to attack enemy ships, the fast ship "Red Horse" that is as fast as a galloping horse, and the heavily armed ship "Sill with double decks on top and bottom." Of course, the building ship is the most important ship and the main force of the sailors. The building ship is a famous ship type in the Han Dynasty, and its construction and development is also a sign of superb shipbuilding technology. The building ship, as the name suggests, is a ship with a building, more than 10 zhang high, and several floors are built on the deck. Each floor has a female wall (i.e., a low wall) that protects against arrows and arrows from the enemy, and there are window openings in the female wall that can be used to fire bows and crossbows to attack enemies. In order to defend against enemy fire, the ship was covered with leather. The behemoth of the building ship is also full of flags, swords and guns, in order to strengthen the momentum. It is in Chang'ancheng, there are the original Qin and Han Dynasty shipbuilding sites, the Han Dynasty Kunming Pool shipbuilding base in the west of Chang'an City, the circumference is as long as 40 miles, and sometimes there are nearly 100 tall building ships in the pool. The building ship is fully equipped, and fiber ropes, oars, sails, and poles have been used. During the Three Kingdoms period, Sun Wu was based on Jiangdong, and the warship built was the largest with five floors and could carry 3,000 soldiers. Sun Quan's "Feiyun", "Gaihai" and other big ships are more majestic and magnificent. Sun Wu sent large fleets to Liaodong and the South China Sea many times. After the Jin Dynasty destroyed the Shu Han, in order to destroy the Wu State, it sent Wang Jun to build a building ship in Sichuan to form a huge naval fleet. Wang Jun organized the construction of the building ship, the largest is 120 steps (one step is six feet), can carry more than 2,000 people, there is a lookout on the deck, the ship can gallop back and forth, known as "the prosperity of the boat, since ancient times". When the state of Wu was destroyed, there were more than 5,000 official ships captured by the Jin Dynasty, which shows the prosperity of the shipbuilding industry. By the time of the Southern Dynasties, Jiangnan had developed to the point where it could build large ships of 1,000 tons. In order to improve the speed of navigation, the great scientist Zu Chongzhi of the Southern Qi Dynasty (429-500 AD) "built a thousand-mile ship and tried it on the Xinting River, traveling more than 100 miles a day". It is a ship equipped with paddle wheels, called a "car boat". This great invention provided a new idea for the improvement of ship power later, and occupies an important position in the history of shipbuilding. In the pre-Sui period, the shipbuilding technology of China is also very exquisite, the dragon boat that Emperor Yang of Sui took to the south of the Yangtze River is very tall, there are four floors, 4.5 zhang high, 20 zhang long, the upper floor has the main hall, the inner hall, the east and west courts. There are 120 rooms on the middle two floors. These ships are "decorated with danfen, decorated with gold and pearls, and carved with strange beauty" (Du Bao's "Miscellaneous Records of the Great Cause"). The lower floor is the residence of the chamberlain. The dragon boat that the empress rode was called "Xiang Yan [chí idiot]", which was slightly smaller than the emperor's dragon boat, and the decoration was extremely luxurious. The large dragon boat of the Sui Dynasty used the method of tenon joint combined with iron nails. It is much stronger and more reliable to use iron nails than wooden nails and bamboo nails. This advanced method was widely used by the Sui Dynasty. In the Tang Dynasty, it was not uncommon for inland river boats to be more than 20 zhang long and carry six or seven hundred people. Some ships can actually open gardens to grow flowers and vegetables, and there are hundreds of sailors alone, and the size of the boat can be imagined. However, why did the Sui and Tang dynasties have such good shipbuilding technology, but they had to use merchant ships to transport naval troops? That's because there is no good sailor to lead the shipbuilding technology. During the pre-Sui period, the best sailors and generals were all from the south, especially the two brothers Zhou Fashang and Zhou Faming. Zhou Fashang and Zhou Faming brothers are the grandsons of Zhou Lingqi, the general of the Southern Liang Cavalry, both brothers once appeared in Southern Chen, and later because Zhou Fashang was framed by Chen Shujian, the king of Changsha in Southern Chen, and took refuge in Northern Zhou. and defeated Chen General Fan Meng. Zhou Faming was also implicated, so he was idle by the Southern Chen court, and the sailors under his command were purged by the Southern Chen court. And his younger brother Zhou Faming is even more famous, once led the sailors to occupy the Ryukyus. However, it is a pity that because of the chaos at the end of the Sui Dynasty, at the beginning, he followed Xiao Mill first, and after Xiao Milling perished, he surrendered to Li Tang, and when Fugong Tuo rebelled, he was ordered to go to quell the rebellion. Zhang Shan'an, the general under Fu Gongtuo, made people disguise himself as fishermen and assassinate him. With the death of Zhou Fashang and Zhou Faming, the sailor completely declined.
