"Your Highness, do you remember the promise you made that day? At that time, I asked you what if you could one day cure this disease. Lu Chen looked at Li Jiancheng solemnly with blazing eyes and asked.

When Sun Simiao heard Lu Chen's words, he directly got up and said to the two: "Go out and go around!" Sun Simiao knew, looking at Lu Chen's expression, he knew that Lu Chen's words involved the prince, this is a big thing, and it is related to Li Jiancheng's promise, although the two did not carry themselves behind their backs when they said this, but Sun Simiao is very self-aware, some things can be known by himself, and some things are not as good as not known.

And now Sun Simiao felt that it was inconvenient for Lu Chen and Li Jiancheng to talk about it, so he got up and left Jingxin Yuan directly.

Seeing Sun Simiao walking out of the house, Lu Chen and Li Jiancheng glanced at Sun Simiao's back, and couldn't help but praise in their hearts: "No wonder people can live so long, just this ability to observe words and feelings, many people can't learn it!" ”

"The promise of the day is the heartfelt words of the lonely, whether it is life or death! Being alone as a prince, although it is not a golden mouth, but it is also a true word, how can he go back on his word? Li Jiancheng looked at Lu Chen with a smile and said, "Lone once said that Lone Shou is more than enough, and he is not enterprising enough, and he is not as strong as the second brother's eloquence, and that position is too tired, as the saying goes, 'All officials worship and stand solemnly, and all the people worship and obey', but in fact, it is 'the emperor's position is not easy to obtain, and the responsibility is heavy and regretful'!" Li Jiancheng sighed when he said this.

"Your Highness, you are right to be a Ming Jun, if you are a faint king, you don't have to be like this!" Lu Chen laughed and teased Li Jiancheng.

"Brother-in-law, what you said is a bit of a joke, how can there be a founding of the country!" Hearing Lu Chen's ridiculous words, Li Jiancheng couldn't help but smile bitterly and said, and even called Lu Chen "brother-in-law" directly with a bald mouth, and this "brother-in-law" directly made Lu Chen stunned.

"Your Highness, be careful! Be careful! As soon as Lu Chen heard Li Jiancheng call himself "brother-in-law", he hurriedly waved his hand again and again, although he was a little happy in his heart, not to mention, he hadn't seen Li Yanjun for so many days, Lu Chen was really a little panicked, as for whether Li Yanjun thought about himself, he didn't know, but according to the TV series and movies he had watched, Li Yanjun's expression was probably also interested in himself, right?

"What's so prudent about that! Now that you see that the grounding period is over, Aya should pick a suitable day to give you and Langya a marriage! Li Jiancheng didn't see anything else, and directly told Lu Chen about Li Yuan's preparation for marriage.

"How can Your Majesty be so anxious? I've only met Her Royal Highness the Princess a few times! As soon as he heard that Li Yuan was going to marry him and Li Yanjun, Lu Chen hurriedly said politely, but there was a twitching expression on his face that was somewhat holding back a smile.

"Laugh if you want!" Looking at Lu Chen's smiling expression, Li Jiancheng couldn't help laughing, "Lone told you, if you hadn't had a grounding order, I'm afraid Aya would have given you a marriage a long time ago, don't you know, as far as Lone knows, Langya must watch the "Qingping Tune" you wrote for her every day!" If it weren't for the many regulations in the palace, I'm afraid that this girl would have run out to see you earlier! Thinking of the time when Li Yanjun sat in Langya Palace every day and watched Lu Chen's "Qingping Tune", the smile on Li Jiancheng's face became even more gentle.

"Hey, hey!" When Lu Chen heard what Li Jiancheng said, he immediately laughed proudly, "I said uncle, are you really not interested in that position?" If so, it's not impossible! Lu Chen looked at Li Jiancheng and said with a smile, quite a feeling of a little devil waving a fork.

"Brother-in-law, you don't have to be so tempted by Lonely, what Lone said is sincere, since he got this disease, he can be regarded as seeing through everything, if this disease is cured, Lone can get away with it, just want to be an idle prince!" Li Jiancheng didn't know if Lu Chen was sincere in saying this, or if he was testing himself again, but Li Jiancheng was telling the truth, without a trace of a smile on his face, and said very solemnly.

"I'm afraid you won't be able to be an idle prince!" Hearing Li Jiancheng's words and the tone in which he said this, Lu Chen also knew that Li Jiancheng really didn't have any thoughts about that position, but Lu Chen didn't want to let go of His Royal Highness the Crown Prince like this, you know, although the history books say that Li Jiancheng is not as good as Li Shimin, but if Li Jiancheng really doesn't have a martial arts strategy, how can he lead the army to fight, you know, the Li family can win this world, Li Jiancheng, Li Shimin and Li Xiuning, the three brothers and sisters, are very meritorious.

Therefore, if Li Jiancheng is allowed to be an idle prince, what is the difference between it and tyrannical things, "what is the most expensive in the 21st century, talent", let Li Jiancheng be an idle prince, how is it possible!

"Why? At that time, the family will be hit, and Datang will inevitably be determined in the world, what will he do if he is not an idle prince? Li Jiancheng looked at Lu Chen with a puzzled expression and asked.

"Tell Your Highness the truth! The enemies of the Tang Dynasty are not inside, but outside! Lu Chen looked at Li Jiancheng's puzzled expression, shook his head lightly and said, "Your Highness, I would like to ask you, do you think the territory of the Tang Dynasty is large?" Lu Chen looked at Li Jiancheng and asked with a smile.

"Nature is big! My Datang is now fertile for thousands of miles, and it is powerful all over the world! Li Jiancheng responded very proudly, and Lu Chen said.

"But has Your Highness ever thought about it, is there really only Datang who is strong in this world?" Lu Chen directly threw a question to Li Jiancheng, and after Li Jiancheng heard Lu Chen's question, his eyes suddenly froze.

"Yes! If there is only the Tang Dynasty in the world, what would those Hu Shang countries look like? After hearing Lu Chen's question, Li Jiancheng secretly thought in his heart, looking at Li Jiancheng's thoughtful appearance, Lu Chen didn't bother her, just looked at him quietly.

"Brother-in-law, you know?" Li Jiancheng thought for a while, looked up at Lu Chen and asked, but as soon as these words came out, Li Jiancheng regretted it a little, after all, the person in front of him who was called "brother-in-law" by himself, but the person known as the "reincarnation of the immortal", if he didn't know, how could he ask these questions?

"I guess I know something!" Lu Chen smiled and nodded, "Your Highness is right, I have thousands of miles of fertile land in the Tang Dynasty, but how many people covet my Datang?" His Royal Highness and His Majesty both thought that what they were doing was to deal with the family, to be honest, there was a way to deal with the family, and even if the family was unbearable, our fight with the family was just a wall of brothers, and it was those people outside who were really ready to deal with it! Lu Chen pointed directly to the north.

"The first is the Turks, the Turks claim to be the first cavalry in the world, they burn and loot our border towns every time, and they are developing things to restrain the cavalry!" Lu Chen said indifferently, "Second, in the northeast, since the Sui Dynasty, Goguryeo has been a vassal on the surface, but secretly it has been dying in my heart, and third, in the east, the island of Waguo, which is across the sea from Silla, should now have completed the unification, and this country is our henchman, the people of this country know the small etiquette and have no great righteousness, and within a few years, they will inevitably send people to our Datang to study..." Although Lu Chen only said it briefly, Li Jiancheng knew that Lu Chen was definitely not talking about it.

"We can conquer other countries, but the Japanese kingdom must be destroyed!" When it came to the word "Wa Guo", Lu Chen's eyes were cold, and he exuded a burst of murderous aura all over his body, which directly shocked Li Jiancheng, Li Jiancheng really didn't expect that Lu Chen, who was sitting in front of him, would have such a heavy murderous aura, which was simply different from the usual gentle appearance of Chang'an County Gongda, and even Li Jiancheng doubted whether Lu Chen had any deep hatred and hatred with this "Wa State", otherwise for other countries, Lu Chen only talked about conquest, and when he arrived at the "Wa Kingdom", he directly wanted to let the other party destroy the country and exterminate the species. Of course, for the fact that Lu Chen was going to destroy the "Wa Kingdom", Li Jiancheng would not doubt that Lu Chen did not have that ability.

"Ahem! That, brother-in-law! Seeing Lu Chen's murderous appearance, Li Jiancheng coughed lightly, looked at Lu Chen and said, "Even if we want to destroy the Japanese Kingdom, aren't we still going to be able to get over it now?" Li Jiancheng reminded Lu Chen softly.

"The sun doesn't set in Datang!" Under Li Jiancheng's reminder, Lu Chen found that he was a little excited, and even said that he was a little out of shape, after all, he was opposite His Royal Highness the Crown Prince, and it seemed a little bad to show murderous aura in front of His Royal Highness the Prince, but when he thought of what the Wa Kingdom had done, Lu Chen couldn't help but have a lot of enthusiasm.

"The sun doesn't set?" Hearing Lu Chen say the words "the sun never sets", Li Jiancheng looked at Lu Chen again in confusion, "I don't know what the sun never sets?" ”

"The sun never sets means that the territory of my Datang is where the sun shines!" Lu Chen can only say this, after all, at this time, people still believe in the saying that "the sky is round and the place is round", even if Lu Chen tells Li Jiancheng that the earth is round, it is estimated that Li Jiancheng will not believe it, after all, there is no actual basis, not to mention that the earth is really determined, or Magellan's circumnavigation of the world, it is seven or eight hundred years after the Tang Dynasty.

If there is no navigation support, but empty words, even if Lu Chen takes out the textbooks in the base, it is estimated that no one will believe it now, and will only say that Lu Chen is a fallacy.

Therefore, Lu Chen explained so vaguely what the sun never sets, and as a result, Li Jiancheng's spirits were greatly lifted after hearing it.

"The sun never sets! What a grand vision! If that's the case, isn't my Datang really the Wanbang Dynasty? Li Jiancheng sighed directly and said, "I don't know if Lone can see that day!" ”

"So, I'm afraid Your Highness, this idle prince can't be done!" Lu Chen looked at Li Jiancheng and said with a smile.
