This news was so surprising that the Hun army went east because of the news of the Roman Empire.

The grasslands in the north were very large, and the range of activities of the Xiongnu was of course also large.

They went from west to east, almost across the whole of China.

They received news from the Roman Empire to the west.

At this time, the Roman Empire was at its peak, a unified great empire.

The most important thing is that they have a large population and are strong, which is comparable to the strong men of the past.

This is not even a divided Han Dynasty, let alone a large empire larger than the Han Dynasty and with a similar population.

The Roman Empire must have been stronger and more powerful than it was ever since.

Quite simply, the Roman Empire grew rapidly under the explosion of population, and then invaded the periphery.

The Romans were too powerful, so they sent a lot of squads out, and one squad went to the side of the Huns.

Yu Fuluo was frightened when he learned about it, and he had to be afraid, an empire that was more powerful than the Han Dynasty, if he came to fight, they would have nowhere to run.

Thinking of this, Yuvro planned to move some of the tribes over and establish a base here, in case the Roman Empire really attacked, they would have a place to retreat.

The letter of state states that they did not move east to plunder Youzhou, but just to have a place to live.

Zhang Yu was shocked, and Xi Zhicai and Gu Yong were even more dumbfounded.

"My lord, in this far west, there is an empire that is even more powerful than us." Xi Zhicai was shocked.

Gu Yong took a few breaths in succession, and then said, "Fortunately, they didn't fight now, otherwise with our divided big man, how could we resist." ”

Zhang Yu put away the national book, and then called Xi Zhicai and Gu Yong to his study.

The three men sat down, the doors and windows closed, and the soldiers surrounded the place, and no one could know what they were talking to.

"There is indeed an empire in the far west, and it is extremely powerful, but don't worry, they are thousands of miles away, and logistics is a big problem, and the logistics of thousands of miles are enough to drag them down." Zhang Yu said.

The two of them naturally understood this truth, but they were too shocked just now.

"However, they have consciously begun to expand externally, little by little, I believe that it will not be long before they can keep up with us, even if they can't hit our Central Plains, they may also occupy the land around us, and after several generations of development, they will finally have enough strength to invade our Central Plains of China." Zhang Yu said.

Zhang Yu simply drew some maps to tell them what kind of existence the Roman Empire was in the west.

The two of them looked solemn, knowing that Zhang Yu's assumption was not unreasonable, and if they couldn't beat it now, it didn't mean that they wouldn't be able to beat it in the future.

"My efforts to develop overseas places have been able to ensure that our Huaxia clan will never be wiped out and that the civilization will continue to be passed on, but I absolutely do not want our Central Plains to be invaded by foreign races one day." Zhang Yu said.

Both Xi Zhicai and Gu Yong felt that they had a great responsibility, and what they had to do now was not only to help Zhang Yu unify China, but also to protect this land of China from foreign invasion in the future.

"The matter of the Roman Empire, we can ignore it for now, they will not be so fast to fight, at least five years, or even ten years later, we still have time."

Zhang Yu continued: "The problem at hand is how to deal with the Xiongnu. ”

"Lord, let the Huns in our north, after all, it is a big hidden danger, once the Huns lack food, they may directly go south, we must guard against them at all times." Gu Yong said.

Xi Zhicai also has this concern, the Huns are very strong, they are not afraid of fighting, they are afraid that they will have to defend every day, so they will consume a lot of strength.

"No, let them come, but to negotiate, there must be a limit to the number of people who come and the scope of their activities." Zhang Yu said.

"Let them come, we can learn more about the Roman Empire through the mouths of the Huns."

In fact, Zhang Yu is not afraid of the Huns now, but the existence of the Huns is really a great constraint on Zhang Yu's troops.

Zhang Yu's 500,000 army did not dare to move easily, and he had to defend this Youzhou, otherwise the Huns would suddenly attack, and the losses would be too great.

An army of 500,000 can play a great role if the army moves south, but Zhang Yu usually sticks to a fixed place with 200,000, and only 300,000 can maneuver.

And the mobile force can't all go out at once, so in fact, Zhang Yu Youzhou can use relatively few soldiers and horses.

There are too few soldiers and horses that can be used, and Zhang Yu has actually been on the defensive in Youzhou.

On the one hand, the Xiongnu were defended, and Yuan Shao was defended on the other.

Xi Zhicai agreed to Zhang Yu's proposal after thinking about it with Gu Yong.

"Lord, our army is 500,000, and this Xiongnu can come over at most 500,000 tribes, of which the army cannot exceed 200,000." Xi Zhicai said.

With 200,000 Xiongnu troops and 300,000 tribes, this strength is not much of a threat to Youzhou now.

Maybe Zhang Yu is still not their opponent on the grassland, but if they want to invade, with the current defense of Youzhou, they can only fight to the ground.

At the beginning, more troops could not break through Liaodong, but now Zhang Yu and they are more powerful, so they are naturally more afraid of the Huns.

"Okay, just like that, in addition to only 500,000 and the range of activities, they also need to give us 20,000 war horses and 50,000 cattle and sheep every year." Zhang Yu said again.

Xi Zhicai and Gu Yong were stunned for a moment, Zhang Yu still wants to blackmail the Huns, you must know that the Huns are still strong now, and if they really want to compete in strength, they will not lose to Zhang Yu at all.

The cavalry of the Huns was in the millions.

But so what, did they gather from thousands of miles away to fight Zhang Yu?

The territory of the Xiongnu is very large, scattered on the vast grassland, and if a million troops really want to come and attack Zhang Yu and them, it will take half a year to gather troops and horses.

"My lord, the Xiongnu are almost unified, and their strength is strong, I'm afraid they won't accept our conditions." Xi Zhicai said.

"If they don't accept it, then we will send troops to harass them in the grasslands, and stop the trade with them, and we have the strength to drive them out of the pastures to the north."

Xi Zhicai didn't say anything to Gu Yong, Zhang Yu was determined to take the opportunity to blackmail the Huns.

The two began to help Zhang Yu draft the national letter.

Reply to the letter and say no directly, if you don't agree, you don't need to come, or call directly.

Zhang Yu was not afraid of the Huns, but he was afraid that the Roman Empire would develop faster than him.

The Xiongnu are not terrible, and there is nothing to scatter that little bit of population into China.

But if the Roman Empire had developed faster than them, it might not be their opponent in the future.
