This is an ancient diplomatic strategy. In the history of the Yuan Dynasty, it has been proved many times that this move can solve temporary problems.

However, Han Yue is more aware that the latest attack from far and near took place in the Tang Empire. At that time, the Tang Empire was strong. They actually found a channel to another world, and thus reached an alliance with a country in that world.

Then the Tang Empire launched a war against the Qin Empire, and in this war, the Tang Empire almost beat down the whole territory of the Qin Empire.

As a result, the allies of the Tang Empire stabbed the Tang Empire behind its back, and a large-scale world invasion war broke out.

In the end, the Tang Empire had to retreat for defense, while the Qin Empire took the opportunity to recover the country and paid the greatest price in this war to help the Tang Empire defeat the invading enemy.

The Tang Empire was ashamed of this, so the two countries signed a non aggression treaty, which agreed that there would be no war between the two sides in the next million years.

In fact, the two countries did the same. At first, the emperor of the Han Empire before Liu Chong felt that there were contradictions between the two countries. They only resolved the contradictions through the non aggression treaty.

In fact, Liu Chongwei found that his parents were wrong.

The Qin Empire and the Tang Empire actually reached an alliance, so the Qin Empire now dares to launch a war in less than ten years, precisely because they are not worried that the Tang Empire will attack them.

But the Han Empire is different. He should always be on guard against the Yin empire's sneak attack, although he knows that the Yin Empire has no national strength to sneak attack the Han Empire.

But what if?

Everyone was afraid of this. If a general of the Yin Empire went crazy and launched a war against the Han Empire, it happened to be the time for the Qin Empire to attack the Han Empire.

At that time, the Han Empire will be in a situation of being attacked from both sides. If the Tang Empire does it again at this time, will the Han Empire destroy the country!

Therefore, the current emperor Liu Chong has no sense of security, so after hearing that the Apocalypse fleet of the Tang Empire was destroyed, he first thought of establishing diplomatic relations with the country that destroyed the Apocalypse fleet.

The strongest diplomatic relationship is that you are my son-in-law and I am your father-in-law.

Therefore, Liu Chong sent Princess Mingyang to the Yan Empire this time in order to make Princess Mingyang the concubine of the emperor of the Yan empire.

If there is such a relationship, he will have Yin Empire and Yan empire as the backing. If Qin Empire and Tang Empire want to jointly deal with the Han Empire, Yin Empire and Yan empire will be the backing of the Han Empire on the periphery.

At first, the reason why the long princess was so strong in the Yin empire was mainly because Liu Chong wanted to take the Yin Empire and make the Yin empire a subsidiary of the Han Empire.

But now it seems that Yin empire is not so easy to deal with, so we should retreat to the second place and let the two countries become allies.

So when Han Yue returned to Longdu again, he took the initiative to find Hua Shangjun and Jiang Gan. They talked for a long time in Longdu cabinet.

Then Han Yue took Princess Mingyang and went straight to Tianlu mountain, the capital of the Yan empire.

……

Just after Han Yue left Longdu, Hua Shangjun and Jiang Gan had such a dialogue in the cabinet.

"The attitude of the Han Empire has changed so much, thanks to the wise Prince long!" Jiang Gan rarely praised Prince long.

However, Hua Shangjun is unconventional. He often praises crown prince long. Instead, he said, "it's just smart, but crown prince long is too bold. He actually made such a special thing with Jiuyao."

Jiang Gan smiled and said, "do you want to say that Jiuyao allowed Qinghe Shangxian to establish a sect branch in the Yan Empire? If so, I don't think you need to. To put it bluntly, our Yin Empire has benefited this time.

And they helped us destroy the navy of the Han Empire this time. Instead of being attacked by the Han Empire, we ushered in an alliance. What a good situation! "

Hua Shangjun said with some disdain, "is that the navy of the Yan Empire? That's our own navy, from Haishan County, under the command of Zhao Buchuan's brother... "

Jiang Gan smiled mysteriously and said, "you're right, but those steel warships were not built by our empire! So why did the Empire give us these things? "

Hua Shangjun was silent when he heard the speech. Jiang Gan said with a smile, "so I say that the Yan empire is not the party who wants to start a war again. On the contrary, I think the Yan Empire knows what it needs, so the business of the Yan empire will be so developed."

Hearing this, Hua Shangjun was a little confused and whispered, "but this burning Empire always makes me feel uncomfortable. I always feel that this country seems to have any ideas about Yin Empire, but I don't know yet.

But I really can't accept that note. If it continues to develop according to the current method, the cabinet will lose the right to coin! "

Jiang Gan said carelessly, "what are you afraid of? Money is created by businessmen and people. Before, we were responsible for casting and giving it to them. Now this matter is not under our control, but has led to a substantial increase in our tax revenue, which is a good thing.

Even if there are disadvantages in the future, at this stage, paper money is only good but not bad for Yin empire.

If when the bad side appears, it's not too late for us to ban paper money. "

Jiang Gan's words made Hua Shangjun unable to refute, but he could only sigh and left.

……

Liu Xinxiu, Princess of Mingyang, is also a princess loved by Liu Chong, emperor of the Han Empire. She is more than ten years younger than the eldest princess and has the cultivation of incarnation outside her body. It is obvious that she is much better than Liu Xinyuan in cultivation.

Since then, Liu Xinxiu is better at socializing, and is much higher than Liu Xinyuan in terms of conversation and EQ.

Han Yue wanted to cross the Yin empire in a month, but what he didn't expect was that when he went to the post station of Longdu to hire a carriage, he saw a rune array flying car.

Han Yue was curious for a moment, so he test drove the rune flying car. Then he decisively bought six flying cars, and then Han Yue took the team on the road.

About three days later, the flying car arrived at Tianlu mountain, the capital of the Yan empire.

Now Tianlu mountain is no longer a religious gate. All kinds of high-rise buildings can be seen everywhere on the mountain, and the imperial palace of Yan empire is at the top of the mountain.

However, when Han Yue drove into Tianlu mountain, he was immediately stunned by the scene here.

Princess Mingyang was not surprised. Instead, she was very calm, but she had an inexplicable expectation at the bottom of her eyes.

According to the data collected by Han Yue about the emperor of Yan Empire, ye Yinlong, the emperor of Yan Empire, has the cultivation of divine harmony. There are many women around him, but there is no queen, let alone a clearly canonized concubine.

Although there are children, there is no crown prince.

Various signs show that ye Yinlong seems to be abnormal. After all, as an Imperial Emperor, if he does not set up a crown prince, once the throne changes, it is bound to cause unrest within the royal family.

Han Yue and Princess Mingyang are in the same car. At the moment, he said with great feeling, "I don't know what the emperor of the Yan Empire thinks. If you don't set up a prince, the princess doesn't know if you can..."

Princess Mingyang said when she heard the speech, "he won't set up a prince. Even if he sees me, he won't set up a queen!"

Han Yue was puzzled to see Princess Xiang Mingyang. At the moment, if ye Xiang and ye Yinlong could see the princess, they would exclaim a name, "Jiang Yan!"

Yes, Princess Mingyang is Jiang Yan who was inexplicably reborn into the Han Empire
