"Zampu, this transaction with Datang is quite strange."

In the distant country of Tibet, because it is the farthest away from the Tang Dynasty, and the two countries have always been friendly.

Therefore, unlike the surrounding countries of the Tang Dynasty, this time the Tang Dynasty directly paid a part of the trading items to the envoys to bring them, so that they could slowly return to Tibet.

On the other hand, what Datang needed was to send the news back to Tubo through carrier pigeons, so that they could bring the trading items to Datang.

In addition to the good relations between the two countries, it is also because Tubo is far away from the Tang Dynasty, and if the envoys return to Tubo to prepare things to send to the Tang Dynasty, it will be too late.

"Oh? Dongzan, tell me, what's wrong? "The man was very young, but he looked shrewd and capable.

He has a name that even Tang Ping knows - Songtsen Gampo!

"Because according to the spies' returns, although the Tang Dynasty seems to have a lot of things to trade with the countries, there is only one thing - they don't use any grain as a trade item!"

Lu Dongzan's words made Songtsen Gampo fall into contemplation, usually the transaction between the Tang Dynasty and Tubo is mainly to exchange tea for cattle and sheep, and this time it is the same, except that the amount of the transaction is a little larger, and the urgency is a little more urgent, and I can't see any difference.

But according to past intelligence, Datang and other countries will come up with some grain in their deals.

And this time, Datang traded so many things with the surrounding countries at the same time, and most of them had grain, but they didn't take out a single grain of grain, which is a bit deep.

"Could it be because Datang just happened to have a big war with the Turks?"

"Probably not, although Chang'an was once short of grain because of the Turkic siege, but after the dispatch of the Tang Dynasty, the price of food in Chang'an City has now returned to the pre-war level."

"Then Dongzan thinks ......"

"Datang is either stockpiling grain and preparing to start a war, or something will happen that will make Datang short of food!"

I have to say that there are smart people everywhere, and Lu Dongzan is one of the smart people of this era.

Songtsen Gampo looked at the map behind him: "Could it be that the Tang Dynasty wants to attack the Turks?" ”

The countries surrounding Datang, this time, except for the Turks, all trade with Datang, to fight these countries is to be unknown, and secondly, everyone maintains a delicate balance, and the possibility is too small.

If there is to be a war, then the greatest possibility is to attack the Turks who besieged Chang'an some time ago.

Lu Dongzan shook his head: "But now the Turks have been divided into two parts since the death of Jili Khan, and it is the time of saber rattling. The attack now is likely to be self-defeating, so that the two divisions that were originally facing each other will join forces to defend themselves against the foreign enemy. ”

Such a simple truth, he didn't believe that the Tang monarchs and ministers couldn't understand it, and now the most correct way for the Tang Dynasty was not to attack the Turks, but to secretly support the weaker side and intensify their internal strife.

"But if it weren't for the ...... of war," the two looked at each other and said in unison: "Does Datang know that there will be a catastrophe this year?" ”

After all, grain storage is a big problem in this era, although all countries have granaries, but there will not be too much grain storage.

First, there is so much productivity, and it is not allowed to fill the capacity if you want to.

The second is that there are too many savings, and the natural depreciation of time is a large amount.

Therefore, Datang bought so much grain at one time, and there are only these two possibilities.

Fighting a war is to fight for money and food, and whether it is fighting at home or abroad, the productive forces of the country will inevitably be greatly affected.

But now after analysis, it is found that Datang does not have the conditions to start a foreign war, then there may be only one left - Datang will have a disaster year.

"There is a big drought in Guanzhong this year, but the Tang government has promoted the Tang plough and keel waterwheel, although the drought has an impact on spring ploughing, it is not fatal!"

You must know that although Tubo doesn't know how many families Datang has, according to the news that their spies have spied on from the missions of various countries, there are definitely a lot of things that Datang has traded this time.

It's just that the drought at the beginning of the year definitely doesn't have to be like this.

"Is it ......?"

"Locust plague!"

In ancient times, there were three major natural disasters, floods, droughts, and locust plagues.

If you want to talk about the C position, it must be the locust plague!

After all, droughts are rarely seen in the bare land, and where there is a severe water shortage, there are also places where water is abundant, and humans use a variety of tools such as keel waterwheels.

There is always a way to reduce the damage caused by drought.

And according to historical records, droughts became more frequent the later in the era.

In Datang, although droughts occur from time to time, they rarely cause a devastating blow to a country.

The same is true for floods, which can be reduced by strengthening river embankments and dredging rivers.

Only the locust plague, in this era, there is really no very good way to fight it.

Once a locust plague has formed, the locusts will eat everything they can see. It is also a natural disaster that all rulers fear the most.

Soon, according to the climatic characteristics of the Tang Dynasty this year, Songtsen Gampo and Lu Dongzan made a judgment similar to that of the Tang Dynasty monarchs and ministers, and it is likely that there will be a major locust plague this year.

In this way, why Datang is in a hurry to trade so many materials with various countries, and most of them are grain, it makes sense.

Songtsen Gampo's hand trembled slightly, and he looked at Lu Dongzan excitedly.

Of course, Lu Dongzan also knew why he became excited, although it seemed that Tubo and Datang had always been good friends.

But Tubo is located on a bitterly cold plateau, and the Tang Dynasty occupies the richest place in the Central Plains, how can they not be blushing?

It is said that there is no eternal friendship between countries, only eternal interests.

In Songtsen Gampo's view, now the best opportunity has come.

At the beginning of the year, the Turks attacked the Tang Dynasty, although it ended with the defeat of the Turks and the death of Jili Khan, but he did not believe that the Tang Dynasty was not damaged.

Coupled with the impending locust plague, if Datang succeeds in completing transactions with various countries, then it should indeed be able to survive this difficulty, but what if this transaction is yellow?

If the Tang soldiers didn't even have anything to eat, would they still have the strength to raise their swords?

Not to mention that now he Songtsen Gampo is not Datang's son-in-law, even if he is really Datang's son-in-law, when he encounters this once-in-a-lifetime opportunity, he should still fight.

So now a difficult choice question appeared in front of Songtsen Gampo, that is, whether to make an obstacle from it and sabotage this transaction, gambling that the Tang Dynasty would not survive this catastrophe, and then Tubo would enter the Central Plains.

Needless to say, the strength of Tubo in the Central Plains has risen sharply.

But if the bet is lost, not only will the good relationship with Datang be ruined, but the two countries will immediately fall into a situation of fighting each other.
