The Supreme Prosecutor of the Tang Dynasty

Obviously, Li Er was really stumped.

How difficult is it?

Just think about it for a moment and you'll understand...

In this era, there are no telephones or the Internet, not even homing pigeons! Want to send a message?

Hurry up! Eight hundred miles urgent!

At most, it's like killing N horses along the way, but in fact, it's slower than this. This is all the result of the beautification of the TV series.

In the past, Datang's territory was not too large and monolithic, so there was no need to worry too much about this problem.

But as Datang's territory grew larger and larger, this problem became apparent.

Not to mention anything else, even just communicating with Turkic regions will take a lot of time! Back and forth, even if it doesn't rain or is blocked by someone, it will take several days at least!

A few days is neither too short nor too long.

However, once something goes wrong, such as a mutiny or something...a few days will be enough time to change the dynasty!

Although it seems that Turks and Goguryeo are quite honest now, especially Goguryeo, which was directly beatenWell, with Li Jing in charge, there won't be any trouble for the time being, but... it is necessary to prepare for a rainy day!

Who knows what will happen next?

Moreover, communication is still the simplest issue.

The big problem is that even if the news comes back, it will still take time for the army to rush over! By the time the army arrived, the day lilies were extremely cold...

The biggest problem was...

Now, they had just conquered the Turks and Goguryeo, and they already had this problem. After that, Datang wanted to expand its territory....how big of a problem is it?

What's more, there is another problem: your uncle's sky is high and the emperor is far away!

What if some general leads his army out in the future, conquers a country, and directly becomes the king, or even ascends the throne and proclaims himself emperor?

This is not impossible!

After all, the sky is high and the emperor is far away. It would be too difficult to fight back...

If this happens, Li Er will have no place to cry, so now he can only think of ways to solve this situation in advance.

It’s best to just put it to bed once and for all and come up with some good way to solve this situation forever! But how to solve it?

This problem has troubled Li Er for a whole winter!

Originally he didn't plan to say it, after all, it would seem a bit awkward to say it, but if he didn't say it, he couldn't solve this problem.

I have no choice but to say it today in front of all the civil and military officials, and let everyone work together to find a way and pool their efforts to see if there is any way to solve it.

As soon as Li Er said these words, everyone's eyes narrowed slightly.

No one who can get to this point is a fool!

After Li Eryi finished speaking, they understood what Li Er meant and also knew that Li Er was taking precautions and taking precautions.

Everyone thinks this situation is normal. After all, it is normal for Li Er to take precautions. If he doesn't take precautions, then there is something wrong.

But here comes the problem again, hell, if you want to solve this problem...it's really difficult!

All the civil and military officials frowned and were thinking hard. Unfortunately, they still had no clue. Everyone looked confused and couldn't speak for a long time.

This is a shackles!

A shackles that there is almost no solution to in the current era!

Now, Li Er wants to break this shackles? How difficult it is! ?

The fastest means of transportation nowadays is horseback riding! But horses are also living creatures. They get tired and hungry, and they cannot run all the time.

Therefore, the speed limit has long been determined and cannot be broken.

The journey is so long, how can we shorten the communication time and even make the army advance faster?

Chen Qiu knows this better than anyone else!

For example, in ancient China, almost every dynasty had a period of time when it was considered prosperous, with strong fighting power, wealthy citizens, and a vast territory...

At that time, China was a truly outstanding group, and they have always stood at the top of the world. At the same time, Which country is China's rival?

In a head-on battle, everyone will be pressed to the ground, rubbed, and beaten like a dog!

However, why did China fail to leave the land of Asia in the end?

It is because of the existence of this shackles!

Once the army reaches too far, it cannot keep up with supplies, reinforcements, or even the most basic communications...

How to fight?

If there were no horses, traveling in ancient times would often be measured in months... By the time we arrived on foot, the day lilies were already cold, and we were still expanding our territory?

Fire a hammer!

Some people have even done research, and the results show that when the walking time between two places exceeds three months, the country basically has no way to control it!

The sky is high and the emperor is far away, that’s the truth!

This shackle has plagued ancient China for countless years. Do you want to break it? Easier said than done!

Fang Xuanling narrowed his eyes slightly, and after a moment, he whispered:"Your Majesty, if this is the case, maybe... we can only alleviate this embarrassing situation by building roads, so that our Tang Dynasty's control can be improved to a higher level!"

Build roads!

Fang Xuanling got to the point directly, and all the civil and military officials nodded, including Li Er.

"What the Prime Minister said makes sense. I have thought hard and considered this method, but... it is very difficult!"

"Today's official roads are all dirt roads. On weekdays, they are fine and the horses can run smoothly. However, in the rainy season or on rainy days, the roads are muddy and the speed will be reduced by half.……"

"The only way to build roads is stone roads! Li

Er let out a long sigh:"Slates are easy to damage, but even better, they are paved with big rocks!""

"But it’s easier said than done to cut through mountains and retrieve rocks? What's more, from Chang'an to various places?"

"How many stones will it cost? How much manpower and material resources? Too difficult, too difficult……"

As soon as this was said, everyone frowned again. yes!

Building roads? Stone roads are already the best, but are stone roads so easy to repair? It's half past one, no need to mention it.

But what Li Er wants is to increase the speed from Chang'an to the 'borders' of all parties!

Moreover, it must be able to pass by the army, which means that the stone road must be spacious, flat, and durable enough!

This is so fucking embarrassing!

It’s not impossible to build roads. If you want to get rich, you must build roads first. Everyone understands this truth.

But the problem is, the price is too high!

Even the current Tang Dynasty can hardly bear it!

For a moment, everyone was silent again and began to think hard.

But... I say I am thinking hard, but in fact, everyone knows that this is an unsolvable problem!

It was originally possible to build roads, but now this method has basically been rejected!

Besides building roads, what other options are there?

There is no way!

All the civil and military officials smiled bitterly. Like Li Er, they all didn't know what to do...

But seeing how uncomfortable they looked, Chen Qiu almost laughed out loud.
