”If there is a way, there is one!”

Sit on the carriage, Xue Lang just hesitated the way, the bottom of the heart some embarrassment: ”just in this way, in the heart is not very bottom.”

Pingyang Princess encouraged to look at him and said with a smile, ”let's listen to it. I'll consult you for your wife.”

Xue Lang nodded.

There seems to be no solution to the influence of weather on the war in modern times. Although we have heard about the so-called meteorological weapons on the Internet, because the people who are not in them can not know whether it is true or not, naturally they do not know what means are used in modern times.

However, it is now in the Tang Dynasty. With the existing technical conditions and Xue Lang's knowledge reserves, it is obvious that he can not make cement, asphalt, or even organize people to build a gravel road.

In this era when all the projects depend on human resources, the productivity is low, there is no machinery to help labor, and there is no surplus population. If we want to build roads, we must transfer civilian workers, and the consequence is the loss of productivity.

In the far distance, the first emperor of Qin asked the private men to build the Great Wall, and the near one was Yang Guang, emperor of the Sui Dynasty, who recruited them to build the grand canal between Beijing and Hangzhou. The newly established Tang Dynasty obviously did not have the ability and confidence to do such a big project.

Therefore, Xue Lang's method can only start from the simplest. Xue Lang said: ”obviously, the best way is to build roads. However, the cost of road construction is quite large, not to mention, the labor cost is also a big problem. Therefore, my method is to collect people, raise money, pile up some piles of sand and stone mixed with soil on both sides of the road, and pile up more, cover with grass or dry leaves and other things. When I go on rainy days, I will see the bad places on the road I'll lay the groundwork. In this way, although the time spent on the road will be slower than usual, at least the road can be connected, isn't it? In addition, it's easy to do this thing. It's just a stupid way to prepare in advance

As soon as her eyes brightened, Princess Pingyang seemed to have opened her mind and said, ”Youyang's method is better than preparing in advance. If you follow this method, you can prepare your weapons and supplies in advance. There are only a few prefectures and counties bordering on the Turks and will be attacked by the Turks. If the imperial court selects a commander in advance and stationed ahead of time, and stores up the grain, grass and weapons before the rainy season comes, it will not lead to weak successors and low morale. ”

Xue Lang nodded with a smile and said, ”that's what it means. So it's a stupid idea. ”

The two men discussed again and added some details. When they went back home, they wrote a Shuo and presented it to the sage. As for the loss of productivity that Xue Lang was worried about, Princess Pingyang said: ”the frontier has suffered from Turkic invasion for a long time. The method of Youyang is based on local materials, which is nothing compared with life and death.”

Xue Lang nodded, thinking that this is the difference between the two people's eyes. Princess Pingyang has a better view of the overall situation, but he also habitually focuses on the detailed place, and the pattern is not enough. This is the difference in standing position. Princess Pingyang was born in an excellent family and had a lot of practical experience. Naturally, she saw it more widely and deeply. Even if Xue Lang has the advantages of advanced information and extensive knowledge reserve, there is still a gap in his vision.

Xue Lang can be used in grain road, but he has no good way to prevent rust of weapons. In terms of the technology of later generations, the general means of rust prevention of iron ware are coating, oiling or painting. In the Tang Dynasty, it was almost impossible, and there were technical difficulties. Finally, we can only use the method of rebuilding the carriage. It is suggested that when transporting, we should add a cover with sloping roof, or tie it with grass, or use felt, so that the rainwater can slide down the inclined roof, so as not to wet the weapons.

In addition, Princess Pingyang proposed that the commander-in-chief should be stationed in advance, and then she would return to the princess's mansion, and the two would write a joint name on the book. They would submit the method to the saints and let the ministers of the political affairs hall discuss and decide.
