Once a person sits on the emperor's throne, his mentality may be different, and Lin Sen can clearly feel that Li Chengqian's attitude towards himself is still different from before.

I don't know if it's because the two were too close before, or because Lin Sen's identity as a "traverser" became known to him, and he became a little jealous and a little unhappy.

The reason why Lin Sen deliberately showed some incredible strength in front of everyone this time was to prevent Li Chengqian from potentially unloading and killing the donkey in the future, or because Lin Sen had nothing to make him fearful, so he had the intention of killing their family to prevent future troubles.

Lin Sen has never been afraid to speculate on the thoughts of the person who sits in the emperor's position with the greatest malice, which can also be seen from the many crazy things that so many people can do for this chair, not to mention that he has the supreme right.

Lin Sen has no intention of being an existence above the imperial power, that is what it really means to fight with any emperor, Lin Sen will use his own performance to show his attitude.

But he doesn't want to become an outcast at any time, after all, he is also involved in his wife and children, as well as the lives of a group of villagers.

Although this degree is not easy to grasp, he still hopes that Li Chengqian, who has a relatively close relationship, will establish this kind of positioning between them, so as to save the future from the fact that irreconcilable contradictions will really break out and lead to a life-and-death situation.

After returning to Chang'an City with good news, Lin Sen was of course called into the palace again, and after talking loudly about the achievements of the Tang Army in front of all the ministers, Lin Sen was called to the harem by the jubilant Li Chengqian and began a long talk.

Regarding how Anshi City was broken in the end, although Lin Sen said this vaguely, Li Chengqian still understood that there was some hidden secret, and it was clear that it was about Lin Sen himself, of course, it was better to ask it in private.

Lin Sen then truthfully explained the process of Anshi City being breached, as for how he collapsed that section of the city wall, Lin Sen did not give a detailed explanation, but vaguely showed that it had something to do with his identity as a traverser.

It may be that he has special abilities, just like Li Chengqian's dead brother Li Zhi, or it may be some cultural knowledge from later generations that he cannot understand is at work.

In short, Lin Sen's goal was achieved, and although Li Chengqian couldn't see it on his face, he did have some jealousy of Lin Sen.

However, Lin Sen's own posture is very low, Li Chengqian has deliberately thought of this, and he probably understands what Lin Sen means.

In fact, Lin Sen was not as calm as he looked on the surface, just like when Li Shimin knew his identity as a traverser, Lin Sen was really cautious and guarded throughout the whole process.

Even if he got Li Chengqian's special permission to go back to visit his wife and children early, he did not completely relax, but let Zhuangzi stay vigilant for a while.

It wasn't until the triumphant army returned that Lin Jiazhuang did not usher in any attack that Lin Sen finally put his mind at ease.

It seems that this time the temptation still achieved the results he wanted.

Especially after the next step on Goguryeo's side came out, Lin Sen was even more sure of his judgment.

In fact, Lin Sen was also very much looking forward to the elimination of Goguryeo, but thinking of an analysis he had seen in later generations, Lin Sen took it as a possibility and told Li Chengqian to listen, of course, it was just a suggestion.

In fact, the harm of Goguryeo to the Tang Dynasty was very limited, and there was originally a buffer zone between the actual control area of the Tang Dynasty and Goguryeo, and in the middle were the Khitan and the local ethnic groups of the Yan Dynasty.

Even if the Central Plains encountered an accident and fell apart, it was not very likely that Goguryeo would take advantage of it, but it would be more harmful to those steppe peoples and the Ya tribe.

Especially if Goguryeo is completely wiped out, and there is no such agrarian national regime in the northeast, curbing the development of barbarian peoples such as the Khitan and the Khitan, and giving them enough space and time, when the Khitan and Khitan really rise, the impact on the hinterland of the Central Plains will be really great.

As we all know, the entry of the two major alien races into the Central Plains in later generations began to develop from this white mountain and black water.

Before the population of the Tang Dynasty increased and the land could not meet the needs of the people, even if it occupied the chassis of Goguryeo, it was difficult for it to have enough people to move to the local area to effectively rule and develop it.

Then after defeating this regime, it is very likely that the barbarian guys such as the Yan and the Khitan will be cheapened for nothing.

Rather than this, it is better to give full play to the very good methods that the Tang Dynasty has been using on the grassland before, or play the game of sowing discord and driving the tiger and the wolf, so that the Khitan and the Ya people and the Goguryeo side will fight to the death and consume each other's strength, which is more in line with the interests of the Tang Dynasty.

While curbing their development, it can also buy more time for the development and strength of Datang's side.

With Datang's current grain output, there is a complete foundation for supporting large-scale population growth, or even an explosion.

Just looking at the growth rate of the number of Dingkou in Datang in recent years, it can be seen that the growth in recent years is even comparable to the previous ten or twenty years.

I believe that it will not be long before the existing land in Datang will not be able to meet the needs of the newcomers.

At that time, foreign expansion and migration will become inevitable, and there is no need for the Tang Dynasty official to forcibly promote.

As long as Goguryeo and Baekje, which have weakened a lot, are defeated, coupled with proper guidance, it should not be much of a problem for the people of the Tang Dynasty to spontaneously "break into the Kanto".

At that time, whether Silla, a friendly neighbor, will go or stay, it is not all in the minds of the Tang Dynasty.

The immediate priority is not to take the white sand and black water, but to conquer the Japanese state.

When Lin Sen described to Li Chengqian in detail what gold, silver and copper mines in the country were large, easy to mine, and had very rich reserves, even Li Chengqian, a guy who was used to seeing these things outside his body, became short of breath, and his eyes turned red because of greed.

The scale of Iwami's silver mountain is gradually expanding, and the silver brought back has made him, the emperor, unable to calm down, and he is paying more and more attention to that side.

It's not worse than that there are so many mines, what I didn't say, I have to beat him, this is the real benefit.

It just so happened that the Wa State dared to send a naval army to provoke the majesty of the Tang Dynasty, even if they were all sunk, that would not work, the majesty of the Datang Dynasty could not be insulted, and the Wa State must be taught a lesson!

What's more, I heard that in the past Sui time, the so-called "emperor" of the Wa Kingdom was very arrogant.

Lay a few important mines first, and by the way, collect some defeated soldiers from the local area to become mine slaves, and make more contributions to the development of Datang.

Li Chengqian was also fed up with the petty fights on the side of Iwami Yinshan, and he had to sneak up on mining slaves from other places, which really affected the efficiency of mining.

While ordering Dengzhou and Laizhou and other places to continue shipbuilding, the Tang Dynasty's naval army and many large and small ships were launched together, and with a full number of Tang soldiers and soldiers, they opened up the Wa State.
