I have to say that the speed of the Chang'an is still very fast.

Originally, Li Yuanba's expected arrival in the Ryukyu Islands would take at least twenty days.

However, as the speed of the ship increased, this time was shortened to 15 days.

In just 15 days, the Chang'an rushed from the Persian Gulf to the Ryukyu Islands.

Because he met Wang Kan's family of three on the way back this time, Li Yuanba was not too lonely on the return trip.

Not to mention, although due to family reasons, Wang Kan did not gain fame and become an official in the court, but he still has real talent and learning.

At first, Li Yuanba was just talking to Wang Kan about some ordinary things, but then he slowly expanded the scope of chatting, astronomy and geography, history and literature, it can be said that he talked about everything.

What surprised Li Yuanba was that this Wang Kan could say a couple of sentences along with everything, and sometimes he had his own insightful words.

Therefore, Li Yuanba's return journey was really full of fun.

When the Chang'an docked at the northernmost tip of the Ryukyu Islands, that is, the closest bay to Datang, Li Yuanba took the two brothers Li Zhen and his own guards off the ship.

They did not directly transfer to the direction of Chang'an in the Tang Dynasty, but planned to take a good look around the land of the Ryukyus.

Since the Tang Dynasty conquered the Ryukyu Islands, Li Shimin has not given up this rich land in the South Seas.

As a result, the battleship waved to the South Seas, and it took half a year to finally take all the land of the South Seas.

When Li Yuanba was ambitious to establish the Nanyang Protectorate in the land of Ryukyu, now this ambition has been realized, and the Nanyang Protectorate has been directly managed by the civil and military generals sent by the Tang Dynasty, obeyed the governance of the Tang Dynasty, and was attributed to the Tang Dynasty.

There is one point that needs to be explained, that is, because Ryukyu was taken by the army led by Li Yuanba, plus his eldest brother. That is, Li Jiancheng lives on the Ryukyu Islands, so Li Yuanba plans to go to see his eldest brother, and he just let his two nephews bring greetings.

Speaking of which, Li Jiancheng was actually seriously ill before returning to Chang'an, and the symptoms of that disease were similar to the asthma of Empress Changsun, and it was far more serious than Empress Changsun.

At the time of Li Yuan's death, Li Jiancheng fell ill, but fortunately, Sun Simiao's treatment was timely, otherwise. His Royal Highness the Hidden Prince, who was at the beginning, couldn't survive.

It was precisely because of knowing this that Li Shimin let go of the idea of killing Li Jiancheng in his heart, but instead asked Sun Simiao to take good care of Li Jiancheng, and also deliberately vacated a courtyard in Chang'an City for Li Jiancheng to live in.

When Li Jiancheng's illness was almost recovered, Li Jiancheng suddenly proposed to go to the Ryukyu Islands to live, and Li Shimin also kept it, but Li Jiancheng said that he would not continue to stay in Chang'an City.

There was really no way, Li Shimin agreed to Li Jiancheng's request to return to the Ryukyu Islands, and also asked Sun Simiao to send two disciples with excellent medical skills. Follow Li Jiancheng to the Ryukyu Islands to prevent Li Jiancheng from falling ill again.

As for Xiao Sitang, Li Shimin asked her over, not to take Xiao Sitang as a hostage. But in his opinion, in Chang'an City, Xiao Sitang can receive a better education and be exposed to more people and things.

Li Jiancheng also understands this truth, although he is very reluctant in his heart. But he agreed, and finally took a lot of wealth, the imperial doctor, and some guards, craftsmen, and cooks...... Returned to the Ryukyu Islands.

Li Yuanba took his two nephews and stayed here for five days. After that, they changed to a smaller steam ship and went to Dengzhou first, then entered the Yellow River through the Bohai Sea, and when they arrived in Zhengzhou, they changed the ship to a steam train, and it took a few days to finally reach Chang'an City.

From the Ryukyu Islands to Zhengzhou, and then from Zhengzhou to Chang'an, it took only seven days, it seems that the transportation of the Tang Dynasty is gradually improving, and I believe that it will not take a few years to be able to unimpeded within the borders of the Asian countries of the Tang Dynasty.

Because Li Yuanba had just returned to Chang'an, he went directly to Zhiyang Wuwang's Mansion, and he didn't know what he was doing in Wuwang's Mansion, and he didn't come back all night.

It wasn't until the early morning of the second day that Li Yuanba rushed back to the palace with his guards.

As soon as he entered the palace, Li Yuanba didn't even have time to drink hot water, and Li Shimin hurriedly beckoned him over.

Standing in the palace, in the apse.

"Brother Huang, I haven't even had time to take a sip of water!" Li Yuanba looked at Li Shimin with a resentful expression, as if Li Shimin owed him 100,000 taels of gold.

"You kid!" Li Shimin, whose temples had already been white, glared at Li Yuanba angrily, and said, "You still put the score, if I don't call you back this time, I'm afraid you won't come back!"

"Hey, don't blame me!" Li Yuanba suddenly began to call Tianqu, "Isn't there a lot of things to do in Dingtiandu, otherwise, who wants to keep floating outside!" ”

"Yes, you're always the one who makes sense!" Li Shimin shook his head a little helplessly, and said, "I called you back this time to let you see Lingyan Pavilion, as for the rest, it's nothing!"

"Lingyan Pavilion?" Li Yuanba said a little strangely: "Didn't you say that let me come to participate in the founding ceremony of Lingyan Pavilion?" Why, how did it get built? ”

"Who said it was the construction ceremony?" Li Shimin said: "It's just a small building, and I still need to call you back when I started to build it?"

Li Yuanba was stunned for a moment, and said in his heart: It seems that this is such a reason, this unlucky herald, can't he figure it out and then pass the order?

"Okay, okay!" Li Yuanba nodded and said: "Brother Huang, you can really do it, get a small building and call us all back, if you build a palace in the future, you can't recruit all the civil ministers and military generals in the court?"

"You don't understand!" Li Shimin shook his head and said, "This is not just a small building!"

"What do you understand!" Li Yuanba muttered in a low voice, suddenly remembered something, and said, "By the way, Brother Huang, how is the development of North and South America and Oceania?"

"I thought you'd hold back and not ask!" Li Shimin laughed and said: "The initial exploration is almost over, I have already sent an ocean-going army to these three continents to build bases, and at the same time, in order to ensure the safety of our ocean-going soldiers, I also asked the Shenji Mansion to take out a large number of firearms, I believe that with the methods of those natives who are still in the stage of drinking blood, they will not be harmed!"
