After Li Xiu's birthday, Li Jin, Li Ke and Li Chengqian also left Chang'an one after another after discussing with Li Zhi a few times, and Li Chengdao and Qi Niang lived in Li Xiu's house for a while, but in the end they had to leave, after all, they had to go back in time when the sea was light, otherwise they would have to take a big risk.

For the sister of Qi Niang, Li Xiu was also very reluctant, and finally took his family to send them to Luoyang in person, and then said goodbye to Qi Niang reluctantly, but when Qi Niang and Li Chengdao's carriage disappeared at the end of the road, Li Xiu couldn't help but cry all over the place, he and Qi Niang are old, and I am afraid that there will be no day to see each other again.

Bidding farewell to Qi Niang and his wife, Li Xiu returned to Chang'an with his family, and just two days after resting, Li Zhi came to visit again, and Li Xiu also invited him to his study to talk in detail, but as soon as Li Zhi came in, Li Xiu raised his eyes and stared at him and said, "Are you really sure?" ”

Although Li Xiu's question has no beginning or end, Li Zhi knows what he is asking, and he smiled slightly at the moment: "Sure, sir, you have taught us that this world is very big since we were children, and it is beyond our imagination, and when I grow up, I find that this world is indeed as big as Mr. said, and with the current conditions, it is impossible for Datang to occupy the whole world, rather than making those overseas places cheaper for others, it is better to let your brothers work hard!" ”

"Very well, you really lived up to my teachings!" Li Xiu couldn't help but show an approving expression when he heard Li Zhi's words, although he had already guessed Li Zhi's thoughts, but this was the first time to openly discuss this matter with him, and Li Zhi's indifferent attitude also showed that he was indeed completely open.

"Sir, you don't have to praise me too much, in fact, I was very entangled at the beginning, worried that if the eldest brother and they develop and grow outside, they may threaten the local area of the Tang Dynasty in the future, but then I also figured it out, if my children and grandchildren can't even keep the local territory of the Tang Dynasty, then I don't have to be the emperor of the Tang Dynasty in the future." When Li Zhi said the end, he also showed a somewhat helpless expression on his face.

In fact, Li Zhi's ambition is very big, so big that he wants to swallow the whole world in one gulp, but he didn't let his ambition overwhelm his reason, especially after becoming the emperor, when he found that manpower was finally exhausted, the territory of the Tang Dynasty had expanded to the limit, and no matter how much he wanted to increase, he would only be unable to control it, so he would connive at Li Chengqian and Li Jin to expand overseas.

Hearing Li Zhi's confession, Li Xiu was more relieved, because Li Zhi's reaction was also human, but then he thought of one more thing, and asked again at the moment: "This time Jin'er and Chengqian are back, you should have agreed on their respective boundaries, where should Your Majesty take as the boundary?" ”

Although Li Zhi encouraged Li Chengqian and others to expand outward, the current intertwining of their forces and the absence of a clear boundary is not a good thing, and if it is not agreed in advance, disputes will definitely arise in the future.

"Yes, this time I discussed it with the eldest brother, and some agreements were also reached, the eldest brother can expand outward, and I will try my best to give them some support, such as population, materials, etc., but they must also stay away from the Tang Dynasty, and the South Seas and the Southeast Peninsula will also fall under the rule of the Tang Dynasty!" Li Zhi spoke again at this time.

Family affection is family affection, but in national affairs, Li Zhi will not become confused at all because of family affection, Li Jin, Li Chengqian, and Li Ke can go overseas, but they must stay away from Datang, so as to avoid future conflicts, and Nanyang and the Southeast Peninsula must be under the control of Datang, otherwise he will not be able to sleep well in the future.

"Yes, Nanyang is related to the security of the southern coast of Datang, and there are also the Wa Kingdom and the Liuqiu Island, which together form the first line of defense of Datang's overseas, so it must be in the hands of Datang!" Li Xiu nodded in agreement when he heard Li Zhi's words, although Li Jin and the three of them are also his relatives, he also has special feelings for Datang, so he doesn't want Datang to be exposed to danger.

Next, Li Xiu asked Li Chengqian about the plans of the three of them, although Li Jin is his son, but Li Xiu has always had a laissez-faire attitude towards this matter, and he has never asked Li Jin about this matter in private, so he is not very clear about Li Jin's plans for the three of them.

Li Zhi also talked about the agreement between himself and Li Jin at the moment, in which Li Jin will return the navy to the Tang Dynasty, but he can take away some of his henchmen, and Li Zhi also promised him that he could recruit some people to follow, as for Li Jin's destination, it was temporarily selected in Australia, but now it has been renamed Xinzhou by Li Jin.

As for Li Chengqian, he will develop towards Tianzhu, after all, his main force is on the southeast peninsula, and he has also invaded Tianzhu, now he only needs to return the southeast peninsula to Li Zhi, and he will go all out to attack Tianzhu, if he controls Tianzhu in the future, he can also enter West Asia or Africa.

Compared with Li Jin and Li Chengqian, Li Ke embarked on another path, that is, to cooperate with Li Chengqian to go to the Americas, after all, the Americas are too big, and the territory controlled by the people under Li Chengdao is limited, and now Li Chengdao is mainly developing in North America, and Li Ke went to South America.

After listening to Li Zhi's introduction, Li Xiu also showed a relieved expression on his face, and even a little proud, not only proud of Li Jin and them, but also proud of Li Zhi's mind.

"By the way, this time Chengdao came back to tell me one thing, they have been experimenting with steam engines in the Americas, and they already have some eyebrows, you have to speed up here, otherwise Datang will fall behind!" At this time, Li Xiu suddenly thought of something and reminded Li Zhi at the moment.

The idea of the steam engine Li Xiu has long been proposed, but subject to materials and technology, has not been able to manufacture a practical steam engine, and later Qi Niang went to the Americas, but also brought the drawings of the steam engine, Li Chengdao has a long-term vision, has been ordered craftsmen to try production, but the process of the Americas is not as good as the Tang Dynasty, so the progress has been very slow over the years, but even so, the steam engine in the Americas is close to practicality, and when there is the heart of the steam engine, the Americas will definitely usher in a great development opportunity.

"Sir, don't worry, I have already ordered the Ministry of Industry to try to produce a steam engine, and now it is also about to succeed, and it may even be faster than the Americas, after all, our side has an absolute advantage in manpower and material resources!" Li Zhi smiled confidently at this time, no matter how good Li Chengdao, Li Chengqian and others did outside, but Datang was their root, and as the emperor of Datang, he could use far more resources than Li Chengdao and others, so he was confident that he would definitely not be worse than Li Chengdao and them.
