More than a month had passed, and the messenger had finally returned.

The envoy didn't care about anything else, so he first went to see Luo Yi and knew the situation of the trip.

It turned out that the king of Goguryeo actually rejected Daxia sternly, which shows his arrogance. The most important thing is that the Goguryeo general Gai Suwen was extremely hostile to Bactria and was afraid that he was not a good person.

There are many reasons for this.

But none of this mattered, because any one of them strengthened Luo Yi's determination to use troops against Goguryeo. If Goguryeo is not eliminated, it will one day become a great disaster in Great Xia.

Now that he is sitting in the position of emperor, Luo Yi naturally has to consider the people of the world. Now that Goguryeo's wolf ambitions are not extinguished as soon as possible, who knows what will happen in the future?

If it was a normal historical process, after Li Tang got the world, he recovered after a long period of recuperation, and only after pacifying and understanding the Turks did he begin to march into Goguryeo.

But the current situation is very different, the Turks have long surrendered to Great Xia, and Yan Yun sent troops to conquer the Quartet, and there is no need to rest and recuperate.

Since the combat power in his hands is sufficient, and the timing is now appropriate, Luo Yi has no reason to delay time. Such ambitious people should be destroyed as soon as possible.

However, Luo Yi is still ready to listen to Luo Cheng's thoughts on the specific plan for using troops. On top of the army, Luo Yi has already handed over power to Luo Cheng, which shows his trust.

After hearing the news, Luo Cheng also came to the palace to pay a visit, and after explaining the matter, the father and son quickly agreed. Goguryeo naturally wants to ask for it, but there is no need to rush it.

Luo Cheng is now training the navy first, and when the time is ripe, he will attack from both sea and land, and when the time comes, Goguryeo has not yet reacted, he will break it in one fell swoop and take advantage of the situation to suppress people.

However, in addition to the use of soldiers, there are still many things that need to be prepared, in addition to soldiers and horses, food and grass are the most important factors. If there is a problem with food and grass, even the most elite army will be defeated.

Therefore, Luo Cheng must prepare all these things before the army sets out, so that everything is ready, and only the east wind is owed.

After the father and son agreed, Luo Cheng went to see Xu Maogong.

In this matter, Luo Cheng was ready to listen to Xu Maogong's opinion. As Luo Cheng's first strategist, his opinion is still very valuable for reference, and Luo Cheng naturally will not miss it.

Then there is Li Jing, who was captured by Luo Cheng before, and he was idle in Xia Jing. If he really sent troops to recruit Goguryeo, he would undoubtedly be a very suitable candidate for general.

Li Jing's achievements in the future undoubtedly show that he has a strong military talent. As long as Luo Cheng has a little experience, he will definitely be able to get a general with considerable ability.

The so-called fierce generals, Luo Cheng has a large number of subordinates, although he is never too many, but this is the case. Therefore, in Luo Cheng's view, a handsome person with a very high command value will be more valuable.

Today's Xu Maogong is also very idle, after all, there is no war in the world now, and he does not deliberately participate in the affairs of the imperial court. On the contrary, he stays in the mansion every day, and usually only sees some old friends.

Xu Maogong's behavior is undoubtedly very similar to that of an otaku, but Luo Cheng knows that he is not an otaku, he is just recuperating and thinking about life. If Luo Cheng summons, he will definitely come in an instant.

Knowing that Luo Cheng was coming, Xu Maogong was not too surprised, a strange person like him naturally knew more things than others. Luo Cheng's arrival was not so abrupt.

"I don't know what the prince is summoning his ministers today?" After Xu Maogong saluted, he asked indifferently.

Hearing this, Luo Cheng couldn't help but be a little speechless, and he was so calm when he asked, it really made people not know what to say.

But Luo Cheng still nodded and said: "If it is decided today, but Goguryeo in northern Xinjiang wants to cause chaos, if it is not pacified, I am afraid it will be difficult for the world, the people, and even Daxia."

Xu Maogong was stunned, he had already guessed that Luo Cheng had used troops abroad, after all, they had also discussed the corresponding issues before, but it was the first time that they had directly put it on the surface.

Although he has been in the army for a long time, Xu Mao's ability to observe people has really been reduced, so he knows that Luo Cheng already has an idea, and after a little thought, he also has his own ideas, that is, he said: "To set Goguryeo, Yi Ye."

No matter when and what time it is, Xu Maogong is so calm, and Luo Cheng doesn't want to dwell on this matter for too long, so he asks: "The military advisor is really powerful, I don't know what strategy can calm Goguryeo?"

Xu Maogong was not ambiguous, and said loudly: "Goguryeo is just a corner of the land, and it is determined by the soldiers of Great Xia, which is not a problem, and the people it relies on are just natural dangers."

"As long as the prince leads a surprise army to the battle, he can surprise the enemy army, and when the time comes, he can send the elite to travel by sea, and then attack from both sides, and Goguryeo will be destroyed in an instant." Xu Maogong said firmly.

The two obviously thought of going together, and Luo Cheng couldn't help but bow his head and said: "Lone is also thinking like this, if Goguryeo is ready, it will just add trouble to our army."

The policy of using troops was thus determined, and the next problem in front of Luo Cheng was to train the navy. As long as the navy is completed, it can march to Goguryeo.

In Luo Cheng's plan, the appropriate time to go on an expedition to Goguryeo was after February. In other words, he has almost two months to train, and he has to hurry.

Fortunately, Yan Yun's army was already well-trained, as long as Luo Cheng selected someone who was good at water, he could succeed with a little training, after all, the ship drawings given by Luo Cheng were the technology of later generations.

Advanced ships are undoubtedly more stable, and they can maintain stability even when walking on the oceans. It won't be like an ordinary riverboat, which has to capsize when blown by the sea breeze.

But Luo Cheng did not take it lightly, he sent orders to the Quartet and transferred 50,000 elite people.

On the shore of the Bohai Sea, a port has long been established here, which is suitable as a training place for the navy, as well as a base.

For the sake of rectifying the soldiers and horses, Luo Cheng seized the time to train, and the adaptability of these soldiers was much stronger than Luo Cheng imagined, but it was only more than ten days to stabilize the naval battle.

In fact, there are not too many naval weapons nowadays, everyone is using short weapons, and there is no way to fight at sea.

But the situation in Great Xia is different, Luo Chengcheng has used gunpowder before, and now he naturally won't put it down. Moreover, when dealing with foreign enemies, Luo Cheng has no psychological burden.

If he used these hot weapons to kill his own people, Luo Cheng would be a little apprehensive, but against foreign races, he didn't have such thoughts at all. On the contrary, it can reduce the casualties of your own side, which is a good thing.

Therefore, Luo Cheng sent people to install artillery on the ships, which is the latest black technology developed. When you think about it, you will be able to play an unexpected effect.
