From the time Luo Cheng decided to kill Li Tang, the formation of this battle had already been marked.

How can the decisive battle between the two superpowers be silent?

Luo Cheng mobilized an army of 300,000 troops, and there would be a corresponding number of migrant workers to escort grain and grass. If there is a problem with the food and grass, I am afraid that the army will not only not be able to start a war, but will fall into a rout.

However, Yan Yun's army has long established a strong self-control ability, and in the face of such a situation, it may not fall into chaos. But there is no doubt that the combat power of the army must be greatly reduced.

So this is what Luo Cheng first plotted for, and this is his plan to take Luoyang City before. With Luoyang, which can be called the second largest city in the world, as the base, a large amount of grain and grass is hoarded, which can naturally ensure that the army is worry-free.

Similarly, since Luo Cheng chose to send troops, it must be a great expense in terms of money and food. It can refer to Emperor Wu of the Han Dynasty to conquer the Xiongnu, and directly exhausted the family wealth of Emperor Wenjing, which made the people's resentment boiling.

But Luo Cheng knew that the same thing would not happen to Yan Yun. Because the Second Emperor Wenjing at that time was not open source, they were just throttling, and the emphasis on agriculture and the suppression of business had long been there.

Yanyun's development gap today is huge, which is the benefit of business. Father Hu had already done business in the Western Regions, and a large amount of gold and silver poured in, and he could fully afford the cost of this battle.

In addition to money, the most important thing is naturally food, and if there is a problem in food, it is the easiest for the people to mutiny. After all, you can't eat enough, who cares about you so much?

But after the system rewarded potato seeds, this was no longer a problem. That staggering production is enough to feed this millions of people, and there is a lot of surplus.

Although it is said that it is greasy to eat too many potatoes, it is an extremely happy thing to be able to eat enough. After all, many people have experienced calamities elsewhere and will not be in the midst of blessings without knowing them.

After Luo Cheng's development, the consumption of potatoes has become diversified, and ordinary people are also enjoying it. Even they firmly believe that when Yanyun dominates the world, life will get better and better.

Luo Cheng came to the barracks, while Jiang Song was training soldiers and horses.

It was Luo Cheng who didn't bother, but rode a horse to his side, and asked with a smile: "Big brother, how is the situation when the army arrives in Beiping today, and what accidents have happened?" ”

Jiang Song raised his head in some surprise and said loudly, "Second brother, why are you here?" The troops and horses from all walks of life that had been mobilized before had already gathered in the barracks, and there were no accidents, just waiting for the time to send troops. ”

With so many troops, Jiang Song still behaved very calmly. After all, he has seen the development of Yan Yun in his eyes, and there is nothing to be surprised and surprised, but he is looking forward to the next battle.

Luo Cheng nodded and said, "That's good, the day of the expedition is getting closer and closer, I'll come over and take a look first." Thinking about that Li Tang, how can he face my Yanyun Bingfeng? ”

Sweeping his gaze, Luo Cheng looked at all these soldiers who were training hard. He suddenly had a lot of pride, with these elite existences, what is Li Yuan?

Hearing Luo Cheng's words, Jiang Song nodded meaningfully, which was also what he was thinking. With the elite rider in hand, why not be afraid of a mere Li Yuan, even if there is Li Yuanba, it is nothing.

Coupled with Luo Cheng's previous preparations, Jiang Song had no doubt about this problem. As long as Yan Yun's soldiers are killed, Li Yuan has no room to resist at all, whether he has Tongguan or not.

But thinking of this, Jiang Song suddenly became a little curious, looked at Luo Cheng and asked, "After defeating Li Tang, what else do you want to do, second brother, do you want to dominate the world, or do you want to do something else?" ”

In fact, Jiang Song was a little dazed, after all, after sweeping Li Tang, the world was also under control. Then what should he do next, Jiang Song was not sure, so he asked Luo Cheng.

Thinking of this, Luo Cheng couldn't help but think of the last conversation with Sun Simiao, and said with a smile: "This world is far more than you and I imagined, there is a vast world outside of China. ”

When Jiang Song heard this, he was a little surprised: "Second brother, are you preparing to expand outward after dominating the world, but it is too much labor and money." ”

With this consideration, Jiang Song is naturally not untargeted, and this time the conquest of Li Tang has already cost a lot. If Luo Cheng continues to expand, it will inevitably cause great pressure on the people, which Jiang Song does not want to see.

Don't look at Jiang Song's cold expression, he doesn't show mountain dew on weekdays, in fact, he is still considering the situation of the people. If Luo Cheng is really ruthless, what should he do?

Jiang Song was not sure, so he asked Luo Cheng.

Surprised by this, Luo Cheng smiled indifferently, he quickly understood Jiang Song's worries.

In fact, this makes sense, after all, Luo Cheng is a time-traveler and knows how big this world is. And because of the addition of the system, Luo Cheng's ambition is not limited to today.

But Luo Cheng also knows very well that if he blindly uses military force, it will not be beneficial. He didn't want to and wouldn't do it, even if he wanted to conquer the world, he didn't have to rush for a while, he was still young and had plenty of time to squander.

This is also one of the reasons why Luo Cheng made a steam engine, the reason why the ancients could not continue to expand, a very important problem is transportation, because the transportation is inconvenient, it can only be limited to this.

As long as the steam engine can succeed and the railway is built to the north and south of the river, the benefits will inevitably be greater than the cost. This is Luo Cheng's goal, and it is also his expectation.

Rather than letting others bully his own head in the future, it is better for him to strike first and take it into his pocket. It is what he does today, not for the benefit of one person, but for the benefit of future generations.

Okay, Luo Cheng's small brain made up for it, and said to Jiang Song with a smile: "Big brother, don't worry, I'm not a person who is eager for quick success, in the future, you and my brothers will work together, how can it not be impossible?" ”

Jiang Song comprehended Luo Cheng's intentions, and it was also clear, the solemn hesitation on his face was swept away, and he said in a deep voice: "Yes, it's for my brother to worry too much, you and my brother work together, what's not to do?" ”

Speaking of Jiang Song, it is also a little strange that the heirs of other people's families kill each other because of the struggle for power and profit. But they are different, they show no desire for power, and Luo Cheng is not afraid of him.

If Jiang Songsheng was in the Li family, he would have amazing strength and a clear mind. Li Jiancheng has to deal with him first, after all, the threat is too big, and it is difficult to rest assured!

This is not a problem, Jiang Song knows the answer, just because they are brothers, there is no need for any calculation at all. As long as Luo Cheng can use him, Jiang Song will naturally go all out, if he is in trouble, Luo Cheng will not stand by.

Jiang Song had made up his mind, and said with his head bowed: "In half a month, the army should go to Li Tang, and when the time comes, Li Yuan will know that the strength of my Yanyun division is not comparable to the previous rabble." ”

The two didn't say anything directly, but they knew their hearts.
