The problem that Jiao Siluo could think of Zhao Zhen could also think of, and even started planning before Jiao Siluo could think of it, but Zhao Zhen knew one thing that potatoes and sweet potatoes could not resist the temptation of Tubo, and at the same time, it was impossible to eliminate the possibility of the Tubo people obtaining it.

Regardless of the rest, the size of a potato or sweet potato is too great.

As long as Tubo sent enough secret spies, the Song Dynasty would almost be unable to guard against it. The long border line and the long period of time of the Tubo people will always allow the Tubo people to obtain these two things.

But Tubo did not even have to send secret spies. Jiaosiluo used another method. Tubo's notices almost filled the streets and alleys of Luoshen City, and were distributed throughout Tubo at the same time.

The content of the notice is very simple. If someone arrives at Luoshe City with two crops of potatoes and sweet potatoes and can be planted, he will be grandly received and rewarded by Tubo Zamp.

The reward was clearly written on the notice, "Ten douches of pearls and jade, thousands of cattle and sheep, and thousands of military and horses. If you want to be an official, you will be rewarded with the general who protects the country!"

This is a reward that has never been seen before, and it is also an jealous reward. Jiao Siluo knew that it was difficult to do it by himself. It was best to let the entire Tubo do it and those who seek profits.

Anyway, the person who benefited the last one was Tubo, and Jiaosiluo had no scruples.

As for the trouble, it is the matter of the Song Dynasty. What the Song Dynasty has to face next are countless people who hope to get rich overnight. As long as a seed is planted in people's hearts, when the opportunity comes, the madness in his heart will grow infinitely.

The cavalry of the Song Dynasty had already begun to prepare for the guards and guards in various places, and the border guards began to take full advantage. The news spread very quickly, and the Song people learned about the news from the Tubo Plateau almost overnight.

The Tubo people have always been honest, and there is no doubt that Jiao Siluo's notice is full of temptation for many people, but this is also the time when the government court is staring at it.

All those who planned this way began to worry in their hearts. Once caught, it would not be a smuggling case, but a betrayal of the Song Dynasty. Not only were they punished, but their family and clans could not escape!

Potatoes and sweet potatoes were planted in the Song Dynasty very wide, and were mostly grown in the north and south, but in the end, it was still more planted in the north. In order to increase the population of the Song Dynasty, Zhao Zhen had already begun to promote these two high-yield crops.

However, because the Song Dynasty had vast land, especially the land with a large number of crops in the south, the gap in the annual demand for food was not very large.

Potatoes and sweet potatoes serve as a food supplement, even as vegetables, and chews.

Fried potatoes are the most popular food in Shendu City recently, and dried sweet potatoes are a kind of food that can be stored for a long time, either becoming military rations in the army, or becoming snacks for the people after dinner......

Such high-yield crops are still the disaster relief food of the Song Dynasty. Once a certain place encounters a famine, the first disaster relief food to arrive must be these two things, which will make people full and not die. This is the best in the eyes of the ministers of the Song Dynasty.

Originally, the courts of the Song Dynasty did not regard potatoes and sweet potatoes as one thing, or at first it was auspicious, but after a long time and getting used to it, they treated it as something they were used to.

Except that it cannot be sold to Tubo like iron tools, there is no special ban.

However, when the Tubo Rao notice was released, the court immediately paid attention to potatoes and sweet potatoes.

At the beginning, no one even believed it, thinking that this was an unreliable rumor, but soon the rumor was verified. When the Tubo envoy went to the Song Dynasty, he asked the reception envoy Bao Zheng, but he refused it by Bao Zheng.

Some Tubo envoys later entered the palace to ask for it, but were rejected by the officials. Now it seems that it is likely that Tubo has no choice but to be unable to seek the seeds at first, and is now forced to make a helpless choice.

In the palace and in the back garden, Sancai stood beside Zhao Zhen and said, "The official family, the cavalry has been out. The Imperial City Department, the black hand, and the dead cavalry have rushed to the pass to the west. The border army, especially the Xuanyi army, have strengthened its defense and inspection..."

Zhao Zhen waved his hand: "It's useless to do this. Pass can only prevent large chariots and horses from passing. How big is a potato? Moreover, this thing is very easy to sprout. As long as you hide it in your arms, choose a secluded road, or even cross mountains and ridges, you can reach Tubo, which is impossible to prevent at all."

Sancai showed unwillingness on his face: "Why would I ask them to go to various places to cooperate with the Sixteen Guards' defense?"

"This is useless. I even suspect that potatoes and sweet potatoes have flowed into Tubo now, and it is too late. Of course, this was as expected by me. When Bao Zheng submitted a memorial on this matter, I already knew that it would look like this. It was due to my promotion, but there was nothing wrong with it."

"The official family has an amazing production of potatoes and sweet potatoes, and it is enough for everyone to do. If they arrive in Tubo, there will be no food shortage in Tubo!"

Sancai's analysis was very reasonable, Zhao Zhen nodded: "Yes! This is a good thing and a bad thing for the Song Dynasty. Although food cannot be steamed on the plateau, it is OK to roast and stir-fry. But what you didn't expect is that once these things are popular in Tubo, the Tubo people will inevitably flock to it, and a large number of people will shift from grazing to farming. Isn't this a good thing for the Song Dynasty?"

Sancai stood there and said nothing. He didn't think of this, and many officials in the court didn't think of this.

Zhao Zhen smiled and continued to fiddle with the water truck in front of him. This thing was made by Xiao Ren, but it was only for viewing. Zhao Zhen planned to transform this thing into a power device and explain it to him in the afternoon.

People are always attracted by inertial thinking. People from all over the Song Dynasty and even Tubo people only saw the benefits that potatoes and sweet potatoes would bring to Tubo, but did not see the harm.

The contradiction between agricultural civilization and nomadic civilization is that in terms of output, the same two lifestyles are also choices made by our ancestors.

Why can nomads be good at fighting? Because they have to grazle, live on horseback, deal with hunger and overcome hunger, otherwise they will die! There is no way to survive, this is a natural choice, regional persecution.

When they can obtain enough output from the land and enough food, grazing will be a side job for them, and fewer people will be grazing, and when they gradually turn to farming, it is the beginning of decline.

The Tubo now made Zhao Zhen feel very familiar because he saw the shadow of the Liao Dynasty in Tubo. After the dynasty established by this nomadic people began to be sinicized, the final result was not to become stronger but to gradually decline and perish.
