After settling Zhang Zihe, Zhang Shangning, and Zhang Mengxing, the heart was excited, the Japanese state has always been a big trouble in the Central Plains, and its harm is greater than that of the grassland peoples, after the grassland peoples entered the Central Plains, except for Mongolia, they were all from the beginning of the killing to the final co-optation. The Wa Kingdom is different, that is to exterminate the Central Plains. And now there are so many immigrants from the Central Plains within the Wa Kingdom. At that time, it is best to take this opportunity to win over the naturalized people in the territory of the Japanese and provoke civil strife in the Japanese state, and it is best to completely turn the Japanese into a colony in the Central Plains to avoid future tragedies. Due to Li Jiancheng's plan, when the Wa State and Li Tang sent envoys and scholars to each other, under the conscious guidance of Li Tang scholars and envoys, the family temples of Qin Shi Huang, Han Gaozu, Cao Cao, and Sima Yi also continued to rise in the Wa Kingdom, which caused a high degree of dissatisfaction with the Wa Emperor government, and the Wa Emperor government ordered that no emperors other than the Wa Emperor such as Qin Shi Huang, Han Gaozu, Cao Cao, and Sima Yi should be worshipped in the territory of the Wa State, and even sent troops to destroy the family temples of Qin Shi Huang, Han Gaozu, Cao Cao, and Sima Yi near Kyoto. The actions of the Wa Emperor caused a large number of naturalized people and their descendants to be dissatisfied, and first the Hatata clan, who claimed to be the first empress of Qin, launched a large-scale rebellion, and the Hatata clan declared that the emperor was a descendant of Xu Fu, and Xu Fu was only a traitor to Qin Shi Huang and a rebel of the Qin state. As the descendants of Qin Shi Huang, the descendants of Xu Fu should be arrested and punished. Immediately afterwards, in the name of helping the emperor quell the rebellion, the descendants of Han Gaozu also gathered troops and horses, attacked cities and plundered land everywhere, expanded their strength, and squeezed more power positions from the emperor. The Xiwen Shou clan was not willing to be lonely, claiming that he was the aboriginal of the land of the Wa Kingdom, Emperor Jimmu was an invader, a butcher who slaughtered living beings, and wanted to declare war on the descendants of Emperor Jimmu to repay the blood debt, and finally the Gao Xiang clan also took advantage of the situation to follow the secession party, and the civil war of the Wa Kingdom made the entire Wa Kingdom become fragmented, and behind every separatist force, there was the figure of Li Tang's 'envoy'. By the time Li Jiancheng's grandson arrived, the Wa archipelago officially became the territory of the Central Plains, and at any time, it was the province of the Central Plains. Li Jiancheng's heart slowly calmed down.

"I don't know how the two children of Chengdao and Chenglu are traveling outside?" Originally, Li Jiancheng sent Li Chengdao and Li Chenglu to other places to practice, which was just an expedient measure to deal with Pei Lian, Feng Deyi, and Xiao Yu's old ministers, and then, after Li Yuan's death, Li Jiancheng changed his mind again, thinking that the children were older, and they should be allowed to practice more outside. Therefore, he issued another decree to extend the time for going out to practice to one year. And, in the future, when the prince grows up to a certain age, he will go out to experience and travel. This will become a tradition of the Li Tang clan, however, when he is old, the children under Chenghuan's knees have not been around for a long time, and Li Jiancheng really thinks about Li Chengdao and Li Chenglu.

In Jiankang City, Jiangnan, a group of nobles dressed in rich clothes wandered around Lanling City.

"Your Highness! ......" shouted a slightly scathing voice, which elicited a warning from the leader at the moment:

"Ahh No, Childe. ”

"Remember, I am now the son of Mu Yizi, a businessman who came here from the capital."

"Yes!" The snarky-voiced man lowered his head and didn't say a word. The group walked while looking at the prosperity of this Jiankang City.

"It is worthy of being the ancient capital of several dynasties, the southern pilgrimage site, this prosperity is no less than Chang'an and Luoyang!"

"Yes! Although Emperor Wu of Liang drowned, but overseas trade is prosperous, Jiankang has the end of the Maritime Silk Road, and, due to the Western Regions and the northwest region of many wars, there are often military conflicts, plus the Jiangnan silk and Suzhou embroidery than Shu embroidery, Bian embroidery is more gorgeous, so the big food merchants here are only a lot more than Chang'an, Luoyang. The rich man nodded. At this moment, a man who looked like a butler came to the group:

"Dare to ask if this son is the son of Mu Yizi from Youzhou?"

"Hmmm! In the following exactly, may I ask who you are? ”

"Childe, below is the housekeeper of Jiankang Zhangjia Warehouse, and our head of the house is waiting for Childe to arrive in the other courtyard. This is a token from our master to the villain, saying that as long as the son sees it, he will understand. The butler-like man handed over a jade pendant. Mu Yizi Gongzi looked at the jade pendant. Nodding.

"Zhang Qianli sees Childe!" Mu Yizi hurriedly held Zhang Qianli up.

"Lord Zhang, please get up quickly, according to the seniority, the kid still has to call the adult uncle and grandfather!"

"Hey! Son! Since ancient times, kings and ministers have been humble, and villains never dare to forget. Childe, a sumptuous banquet has been prepared for Childe, and the dust is washed for Childe, Childe, please inside! "This Mu Yizi son is Li Jiancheng's eldest son - Li Chengdao, the king of Hengshan. Zhang Qianli's wife is the cousin of Empress Dowager Xiao, so in terms of generation, Li Chengdao calls Zhang Qianli his uncle and grandfather.

"Lord Zhang, the lonely king's trip to Jiangnan this time is not to enjoy the mountains and rivers, but to see for a long time!"

"Oh! His Royal Highness wanted to ...... "After receiving the news that Li Chengdao, the king of Hengshan, was going down to the south of the Yangtze River, the Zhang family, the head snake in the south of the Yangtze River, did not know how happy they were, according to the Zhang family's idea - Li Chengdao was long in the hands of women, and when he came to this Jiangnan, he must have traveled to the mountains and rivers, and he was a beautiful woman, even Zhang Qianli himself, and he also secretly collected a lot of beauties for Li Chengdao and prepared a lot of 'programs'. However, Li Chengdao directly stated that he was not traveling in the mountains and rivers, and Zhang Qianli felt a little dizzy and caught off guard.

"Childe, I just don't know what Childe wants to know?"

"Lord Zhang, the Lone King came to your manor, just for the sake of his relatives, as for what the Lone King wants to know, it seems that it is none of your business!" After Zhang Qianli listened to Li Chengdao's words, his face was a little embarrassed, but he was afraid of Li Chengdao's identity, so it was naturally difficult to attack. Zhang Qianli's wife saw that the atmosphere was a little embarrassing, and immediately raised her wine glass:

"Master, Chengdao is rare to come, Chengdao, come, eat, drink! Master, you can eat too! This is the authentic Jiangnan kitchen, the ancestor of the chef who made these dishes was the imperial chef in the palace from the Liu and Song dynasties of the Southern Dynasty, come, you all try his craftsmanship! Come, sir, this is your favorite winter bamboo shoot venison, and, Chengdao Wangye, this silver-whiskered fungus is the most dusty, you can taste it. After the banquet, Li Chengdao left the Zhang family's courtyard with the servants. Late at night, Zhang Qianli stood in the courtyard, sighing, and Zhang Qianli's wife gently draped a cloak on Zhang Qianli's body. Zhang Qianli looked at his wife and smiled gently:

"Husband, are you still angry about the matter of the prince of Chengdao? Ay! The prince of Chengdao is still young, besides, Chengdao has been in the capital for a long time, and he doesn't have much friendship with our family, you are so enthusiastic, it is hard to guarantee that it will not arouse the disgust of the prince. Zhang Qianli looked at his wife, nodded, and shook his head again. I said in my heart - Madame! You don't know, it's not for the husband to spend his heart on Li Chengdao, it's really our Zhang family in crisis, and we must bet on Li Chengdao!

After Li Chengdao left Zhang Qianli's house, he stayed in the inn for one night, then left Jiankang City and transferred to Longjiang Shipyard. Longjiang Shipyard, since the period of Gaozu of the Western Han Dynasty and the reign of King Liu Bi of Wu, has been an official shipyard and has been undertaking the task of building ships for the government and the army. And the principal of Longjiang Shipyard is still a member of Empress Dowager Xiao's clan.

"Childe, please come here." Li Chengdao followed the director of Songjiang Shipyard and watched all the way, around Songjiang Shipyard, there are many big trees, some of which are extremely thick, and they are all over 100 years old. Li Chengdao looked at these big trees in amazement - logically speaking, shipyards generally need a lot of wood for shipbuilding, how can there be so many big trees that are more than 100 years old? The director of the shipyard seems to have seen Li Chengdao's doubts:

"Childe! Although these trees are old, the hull of the ship needs to be sunken wood, and these trees, the wood is soft, not suitable for sea navigation, so generally from Jingchu, Bashu and Lingnan area to purchase wood, especially on the sunken wood, the sea wind and waves, the ship made of sunken wood is relatively stable, and there is a far-reaching history of these trees, the oldest one can be traced back to the Three Kingdoms period, so, just like the gods, the boatmen like to ask for good luck, generally after the ship is built, the boatmen before entering the sea, Worship the god of the tree for protection. In the introduction of the shipyard director, Li Chengdao learned a lot of knowledge that he could not learn in Chang'an.

"Childe, an armed ship built or modified for combat purposes in ancient China. Generally, it can be divided into three types: large, medium and small. The large ones are the main warships, called "ships" or "building ships", with 2, 3, 4, or even more than 4 decks. Medium-sized are warships used for offensive pursuits, such as "Mengchong", "Xiandeng", etc. The smaller ones are the clippers used for sentinel patrols, such as "yachts", "red horse boats", etc. In order to meet the needs of being able to seize the upper hand and pursue enemy ships during combat, most warships are specially designed and manufactured for combat to ensure that they have good seaworthiness, maneuverability, and high speed. There are also some warships that have been modified from the type of fishing or merchant vessels, or have been temporarily modified with fishing boats or merchant vessels to meet the needs of warfare. The number of passengers on the warship is calculated according to the standard of "meter weight", and the weight of each person is subject to 2 stones. The warships built by our dynasty are mainly the "five-tooth" big ship designed by Sikong Yang Su in the previous dynasty, with 5 floors, more than 100 feet (about 29.5 meters) high, can accommodate 800 soldiers, and has 6 shooting rods, 50 feet (about 14.76 meters) high, to smash enemy ships. In addition, please look here, Your Highness, this ship is called the Sea Falcon, and its characteristics are: although the wind and waves are high, there is no capsillation, it is an all-weather warship, and it is one of the famous combat ships in the naval division. It can be an attack ship that can operate in bad weather. The size of the boat is not large, the head is low and the tail is high, the hull is wide in the front and narrow in the back, and it is designed and built to imitate the appearance of the sea falcon. There are four to eight floating planes on the left and right sides of the boat, which are shaped like the wings of a sea falcon (now called the water piercing, or the pry head), and its function is to enable the boat to sail smoothly in the stormy waves, and has the function of draining water to increase speed. The left and right sides of the cabin were walled with raw cowhide to prevent the waves from breaking the wooden hull and to prevent fire. A half-man-high female wall was also added to the cowhide wall, and there were crossbow windows in the wall to facilitate attacks. The deck was littered with all kinds of tooth flags and war drums to make a strong noise. ”
