Let's get it...... The sound of falling rain is particularly loud, the small inn between the two cities was originally simple, the eaves are made of simple folk stucco tiles, this kind of tiles are all fired from ordinary yellow mud, because there is no strict process requirements, so most of the finished products are hollow, not only fragile but also make a loud sound when hitting, at this time the eaves of the small inn are suffering from the blow of raindrops, and the sound of one after another is like someone playing lamely.

Jiang Weizhen, who hadn't slept all night in such an environment, didn't wake up, lying on the bed, saliva flowed from the corners of his mouth to the pillow, shiny. Shen Ming is different, he also didn't sleep all night, after coming back, he just slept in a simple clothes for an hour, and after getting up, he ate something to fill his stomach and didn't be attracted by the sound of rain.

Squeak, Shen Ming opened the window of the room, the rain outside was already very strong, so big that the pedestrians on the road were about to see clearly, Shen Ming could only see a white expanse, and what he heard in his ears was the sound of cheering.

"It's ...... What time is it? Finally, Jiang Weizhen was woken up, if he couldn't wake him up so loudly after opening the window, then he was really hopeless. Jiang Weizhen wiped the corners of his mouth and asked, "Master Shen, it's raining heavily outside?" ”

Shen Ming let go of his body and completely exposed the window in front of Jiang Weizhen, Jiang Weizhen immediately jumped off the bed when he saw the pouring rain, and shouted at the top of his voice: "Oh my God! This spring rain is also coming too quickly! ”

Rao is Shen Ming, a person who is used to seeing big scenes, is also a little ignorant of Jiang Weizhen's behavior, he was directly pushed aside by Jiang Weizhen, and then this usually polite scholar grabbed the window with both hands, and then shouted with an extremely frightened look: "Wasn't it still cloudy when we came back this morning?" It's going to rain so much, it's ...... This is beyond my expectations! ”

Is this a never-before-seen heavy rain or what? Shen Ming was almost amused by Jiang Weizhen, and before his smile could be seen on his face, he began to realize the reason behind Jiang Weizhen's abnormal performance.

"Master Shen, I have to go to Huangshui immediately!"

Jiang Weizhen didn't care about Shen Ming, put on his shoes and ran downstairs, and was directly drenched by the heavy rain at the door of the small inn. Suddenly, an umbrella was stretched out above his head, Jiang Weizhen turned his head to look over, and saw Shen Ming standing behind him with an umbrella.

Ouch, I really have a mess in my brain, and I ran out of such a heavy rain without an umbrella. At this moment, Jiang Weizhen looked at Shen Ming and was a little embarrassed, Shen Ming handed the umbrella to Jiang Weizhen's hand and said, "It's raining so hard, make an umbrella, otherwise you will get wet, I'm afraid you will be infected with the wind cold." ”

Shen Ming was the first to walk into the heavy rain, Jiang Weizhen hurriedly took off his cloth shoes and stuffed them into his arms, and followed barefoot. As soon as he entered the heavy rain, it was an all-round test for people, first of all, his eyesight, it was obvious that Shen Ming was not far in front of him, but Jiang Weizhen could almost only rely on Shen Ming's blue robe to distinguish it. Fortunately, Shen Ming was wearing a dark blue robe today, and if he changed to the moon white, which is the most commonly worn on weekdays, then Jiang Weizhen would be completely blind. The second is the ear power, the sound of this rattling has been filling the ears, and there is no stopping for a moment, except for the sound of the rain, I can hardly hear any other sound.

Under the double torture of eyesight and ear, Jiang Weizhen's every step is a waste of effort. Because of the heavy rain, the streets have begun to accumulate at this time, and these dirt roads that are not part of the official road are potholes, and they cannot be felt on sunny days. Jiang Weizhen had already taken off his shoes and walked more slowly, but he was anxious, and it would not be a good thing if he and Shen Ming were separated.

Jiang Weizhen was anxious for a while, and hurriedly quickened his pace and ran a few steps, just a few steps into a deep pit, his feet and neck were crooked, and the whole person was about to fall into the muddy water. Jiang Weizhen felt that his waist was being helped by someone, and his originally fallen body fell into Shen Ming's arms.

This...... Jiang Weizhen asked himself if he was a big man, and the embarrassment of being more and more embarrassed twice in a row made his cheeks red, and he hurriedly got up and thanked him. Shen Ming replied very calmly, "It's okay, you must be careful when walking in such heavy rain." Why do you take off your shoes, bare feet are easy to hurt. ”

"These cloth shoes are not waterproof in the first place, and they are completely useless when they step on muddy water. I've just bought it for two months, and I'm a little reluctant. ”

Shen Ming smiled and didn't say anything, but he obviously slowed down his pace on the next road, the closer he got to Huangshui, the more difficult the road became, Shen Ming even directly supported Jiang Weizhen, and the two walked hand in hand.

Under the washing of the torrential rain, the Huangshui is no longer the original Huangshui, and the originally wide river surface is like a vast ocean, with turbid waves surging. Jiang Weizhen was most concerned about the city of Bingzhou on the other side, he stood on the high ground and tried his best to look, but no matter how hard he tried, he couldn't see the situation on the other side at all, and all he could see was clouds of white rain and mist.

"I know you're worried about something."

"If this rain continues like this, it will not be a good thing for Huazhou and the capital!"

"Huangshui originates from the mountains behind the capital, and from the topography, it is the highest location in the capital, and this Huangshui will not flow into the capital even if the amount of water increases."

"The terrain of the capital is indeed the highest, but Master Shen, I suspect that the target of the Tang people is Huazhou at all."

"Huazhou? The topography of Huazhou ........"

Shen Ming fell into thought for a while, he wanted to see the city of Huazhou not far away, but the heavy rain curtain blocked all his vision. Jiang Weizhen said loudly: "Master Shen, everyone in Huazhou thinks that the terrain is higher than that of Bingzhou, but in fact, the topography of Huazhou is actually the same as that of Bingzhou, and the reason why people have the illusion that Huazhou's terrain is higher is all due to the trend of Huangshui. ”

Shen Ming began to understand when he was reminded like this, and it became more intuitive for him to look at Huangshui again. Indeed, when people judge the height of the terrain, they will always use a fixed location as a comparison, and the best setting between Bingzhou and Huazhou is Huangshui, if Huangshui is a plane, then Bingzhou will be lower and Huazhou will be higher. But what if the water is not flat in the first place?

Although the direction of the river does not change significantly for a long time, it is only judged by the naked eye, in fact, the bottom of the river has undergone unknown changes under the daily washing.

Take this river as an example, there is a big flood season almost every two years, and the water at this time is very abundant, and the river will take away a lot of sediment, which will invisibly change the original course once the sediment is accumulated at the bottom of the river. If the water flow is uneven, then the sediment will be more piled up in one position, and over time, this position will slowly rise, if the sediment is piled up on the side close to the state, then in fact, the river outside the city is very deep, and the same water surface under the side of the state is more sediment and more is the real river water under the water surface of Huazhou.

"How could you know such a complicated situation if you didn't go down to the water yourself? Are you right? ”

"Master Shen, I really don't know anything when it comes to force, but when it comes to water conservancy, I know a lot. The preliminary judgment is that the river does not have to dive to the bottom to see, last night the moonlight was bright, and I saw that the ships on the opposite bank made such a guess. ”

"Ships in the Lower Don? These ships must have sunk to the bottom of the river at this point, right? ”

"That's the worst!"

"Why? The scuttling of the ship is a good thing for us. ”

"What a fallacy! Heck, those shipwrecks will protect the state! As for the detailed reasons, I will explain to you in detail on the way, we must go back to Beijing immediately! ”

"This heavy rain is very bad for our trip."

"No matter how unfavorable it is, I can't wait, when the people of the Tang Dynasty really start to act, it will definitely be a catastrophe for Huazhou!"

Jiang Weizhen pulled his legs and ran towards the small inn, and when the two of them rushed to the inn with great effort, it was already dusk, and it was obvious that the rain at this time still had no tendency to decrease. At Jiang Weizhen's insistence, Shen Ming hired two horses at a high price, and the two began to gallop towards the capital despite the rain.

At this moment, Yong Wujian, who was standing at the head of Bingzhou City, looked at the continuous rain curtain and involuntarily showed a satisfied look. It's really God who helps me, this time even God is on our side, Yang Zhong, Yang Zhong, do you think it's useful to use that kind of indiscriminate little tricks? It's a self-digging grave! Soon you will see the power of the wrath of the Divine.

Yang Zhong sneezed, he had already sneezed a few times, maybe it was a cold, but he didn't pay attention to it. This kind of bad day is also uncomfortable for Xia Tang, as long as the rain does not stop, he will have some time to relax.
