Why did you think of Xu Dong for the first time?

Naturally, because Xu Dong is very familiar with geography and weather, Xu Dong will definitely notice such a strange heavy rain.

Chengxin stood up and said: "Your Majesty, Weichen thinks that the rain in Chang'an is not directly formed over Chang'an, but more like it is floating from afar!" ”

As soon as this remark came out, everyone fell into deep thought, they didn't know much about the formation of the heart, but if the clouds were floating from a distance, they still knew something.

Li Shimin was the first to react, pointing to his heart and trembling a little and said: "What does Aiqing mean is that there is a place that is more waterlogged than Chang'an?" ”

Satisfied, nodded, looked at Li Shimin and continued: "Please ask Xu Dong to explain this matter to you, I don't know the specific things very well!" ”

As soon as this remark came out, it was not to shirk the responsibility, mainly because the typhoon and the rainstorm would only be known when they arrived, and Xu Dong said that there would be a rainstorm when the sky was cloudless a few days ago, which made Xiangxin unconvinced.

Xu Dong outside the hall was quickly passed in, only to see that Xu Dong was also soaked and crawled into the Jinluan Palace, only to see him kneeling in the center of the hall and said to Li Shimin anxiously: "Your Majesty, the rain in Chang'an has been much lighter, if Weichen's prediction is right, it is unimaginable for us to experience floods in the south!" ”

As soon as these words came out, the officials became even more agitated, and the court was more like a vegetable market.

Wei Zheng dragged his sick body to Xu Dong's side, pulled his collar and said: "You dare to be responsible for what you say, do you know how much responsibility you have to bear when this statement comes out!" ”

Wei Zheng is not afraid that Xu Dong will be alarmist, he is afraid that Xu Dong will become a prophecy, so how should the people live!

Li Shimin's face is also a little pale, the land south of the Yangtze River has always been the lifeblood of brokers, although the people have always been very rich, but only a few years ago they experienced drought and locust plagues, and this year they have to experience floods, and the people of Jiangnan have long been unable to bear it under repeated tosses.

Xu Dong was not frightened by Wei Zheng's appearance, gently brushed away his hand holding his collar, and then said to Li Shimin: "Your Majesty, there is a map, Wei Chen has deduced the ins and outs of this storm, maybe he can answer a question or two for you!" ”

Li Shimin looked at the old eunuch on the side, and the old eunuch on the side immediately went to the back to retrieve a map, as well as a dry towel, and handed it to Li Chengqian and Xu Dong respectively.

Xu Dong can have this treatment naturally because he wants to mark the map, and he is wet for fear that he will drip water stains on the map.

Xu Dong took the brush handed by the little eunuch, and then the scroll held up by the old eunuch marked it on the map, although Xu Dong knew something about the climate, but he also marked two routes on the map.

One is a typhoon coming from the south and blowing to the north, which also brings dark clouds and heavy rain, and the other is a typhoon coming from the southeast coastal area, turning around in Datang and finally drifting to the north, passing through Chang'an and then drifting to the east.

The two routes seem to be full of suspense, but no one has the heart to question Xu Dong, but carefully studies the places Xu Dong paints and the towns he has experienced.

Li Shimin also took over the scroll at the first time and studied it carefully.

In fact, in the eyes of more people, they also know that the rain is more like drifting from afar, so the distance has at least experienced the same rainstorm as Chang'an, but it is often the wind that brings the rain, and this time the rainstorm and the wind are coming at the same time, not one after the other, which makes everyone feel lucky.

Li Shimin looked at the map while looking at the non-stop rain outside the window, and after sighing, Li Shimin said: "Zhong Aiqing has worked hard, and he has not eaten anything after a day's work, I have ordered someone to arrange some food, all Aiqing will eat something and rest first!" ”

With that, Li Shimin left the dragon chair with a wave of his hand, turned around and walked to the back.

Xiangxin thought that he had really rested, although he was a little strange in his heart, he still waited obediently for food, but Li Chengqian quietly pulled Xiangxin and Xu Dong to the apse.

Along with them, there were also Li Tao, Wei Zheng, Fang Xuanling, and the eldest grandson Wuji.

Li Shimin sat on the chair in the apse and looked at Li Chengqian helplessly, "How does the prince think this matter should be handled!" ”

Li Chengqian naturally knew his father's difficulty, touched his head and said: "Erchen thinks that everything will have to wait for the rain to stop, and now it is too early to say that the flood situation in the south is too early, no matter whether there is any problem in the south, someone will still come to report, so we might as well wait a few more days!" ”

As soon as Li Chengqian's words came out, Fang Xuanling and Wei Zheng's faces were a little unsightly, not that there was anything wrong with what Li Chengqian said, but it was too decent, like the words of an old man in the court.

Chengxin continued Li Chengqian's words and said: "Your Majesty, Weichen thinks what the prince said is extremely true, first, we must wait for the rain to stop, or wait for the rain to become lighter before doing things, and second, the south will send sentries to inform us that we must also wait for their information, but we don't have to wait in Chang'an City, maybe we can send troops to meet them outside, and we can also welcome the large army of General Cheng and General Hou." ”

While helping Li Chengqian to fill in the gaps, he continued: "The minister thinks that the emperor might as well issue two holy decrees, one holy decree is the message that there is a flood in the south, and General Cheng and General Hou can deal with it, and the other holy decree is the message that there is no flood in the south, so that General Cheng and General Hou can repair for a while and continue to rush to Chang'an!" ”

Li Shimin nodded and looked at Xu Dong again: "Xu Aiqing, why did you draw two routes on the map, can you explain it to me?" ”

Xu Dong naturally didn't dare to be sloppy, and hurriedly stepped forward and said: "Your Majesty, these two routes are the storm carrying a large amount of energy from the sea, but these energies move little by little with the clouds, like a horse-drawn carriage, and gradually they can't be pulled, so I have the possibility of these two routes, but the starting point is unpredictable." ”

Most of these things that Xu Dong said were taught to him before, but I didn't expect Xu Dong, this kid, to have an amazing comprehension, and he really explained the relationship between storms and typhoons.

Li Shimin also knew what Xu Dong meant, nodded and looked at Fang Xuanling, after Du Ruhui's death, Li Shimin discussed more things with Fang Xuanling and the eldest grandson Wuji.

Fang Xuanling touched his beard and said: "If what Xu Hanlin said is true, then the flood situation in the south is unimaginable to us, this is not only the matter of the people receiving floods, but also the problem of whether the people have food to eat this year and even next year!" ”

The eldest grandson Wuji also took over and said: "I forcibly mobilized most of the rations in the country in the previous war with the Turks, and now there is a flood again, the people can't afford it, and the court can't afford it!" ”

As soon as these words came out, everyone was silent, everyone knew that what the eldest grandson Wuji said was true, and they also fell into contemplation.

Li Chengqian immediately thought of the king of Gaochangguo, who was still in Chang'an, and only heard him say cautiously: "It seems that there is a lot of grain in Gaochangguo, and the old king is still in Chang'an, so many misunderstandings before may be solved with food!" ”

The most important reason why Gao Changguo has always been valued by everyone is because of the high grain production there, and the old king is willing to donate these grains, so he has not been harassed by neighboring countries and protected by the Tang Dynasty.

As soon as Li Chengqian's words came out, he always felt that something was wrong, but before he could figure it out, Wei Zheng on the side clapped his hands and applauded: "Your Majesty, what the prince said is extremely true, that Gao Changguo is treacherous, if they are not punished in the future, it will be a scourge in the future, if they can give us some food to help us get through this difficulty, then we can also forgive them for their behavior this time!" ”

Li Shimin nodded, he originally wanted to punish Liwei severely for the king of Gaochangguo, but now it seems that he may still have to ask him.

Thinking of this, Li Shimin said silently, "It's just that in this way, Hou Aiqing will be wronged!" ”

Li Shimin realized that something was wrong as soon as he said this, the king of Gaochangguo became the savior, so Hou Junji, who captured him, naturally suffered a backstab, which was originally a great meritorious thing, and now it is not bad to be punished, and the old king is not a fool, seeing such a heavy rain in Chang'an, he will also open his mouth if he can't keep it.

The eldest grandson Wuji thought for a while and said: "Your Majesty, instead of being controlled by others, it is better to cut the grass and eradicate the roots, we think of the law to ask Gao Changguo, it is better to directly send troops to level Gao Chang and rob them of their food!" Who made them perfidicious! ”

In fact, there is no need for the eldest grandson Wuji to say, Li Shimin has already moved this thought, but this move is still not considered, Fang Xuanling opened his mouth and didn't say anything, Wei Zheng also lowered his head and looked like he had nothing to do with him.

In the end, it was Li Tao who said on the side: "This is serious, Gaochang and my Datang are not only subject to the country, but also involve a wide range of things, not only trade and cultural connections, but also the layout of family fame!" It's not something we can decide with a single sentence! ”

Li Tao is right, although he has no property in Gaochang, but these days many famous families have found him, hoping that he can save the life of King Gaochang, and even many old people who have had lifelong friendships have also found themselves, and he does not need to elaborate on the depth of his involvement.

Li Shimin naturally knows these things, the Jiangnan Shi clan, the five surnames and seven wangs, they are the masters behind the Tang Dynasty, they enslave the people of the Tang Dynasty, and they are the ultimate opponents they want to eradicate, the king of Gaochang entered Chang'an for a few days, these famous families have made a lot of things for their own interests, if Gaochang really destroys the country, the consequences are unimaginable!
