Struggle in the Steam Age

"Huh?" When Lawrence said what he found, Nora also frowned and picked up the form and looked at it. Soon she found out the abnormalities in the data on the form. "If evaporation and its various losses are considered, the divine power on the land should be lower than the divine power imported from the river, but now the combined divine power on the land is far higher than the upper limit of the divine power injected from the river."

"That is to say, there should be other sources of divine power in this area. And the area covered is larger than we imagined." Lawrence said after testing for a few seconds with his hands behind his back. "After all, this place is relatively dry. Although there are more than 70 days of precipitation every year, the amount of precipitation each time is not a lot. Therefore, the groundwater in this area should mainly be replenished by this big river, and there are not many other sources."

At first, Lawrence thought about whether it might be the problem of groundwater, but after getting the statistical report of local precipitation from Aunt Mia and the Church of Agriculture, he found that the local precipitation is too little. Theoretically, the main source of replenishment for local groundwater It's still a big river that doesn't seem to have a small flow.

"Then where did these divine power pollution come from?" Nora sat on the edge of the table and looked at Lawrence and said, her little face was full of doubts. Before, she thought that after careful investigation, the direction of the source of pollution could be roughly identified through big data, but she didn't expect that after the big data came out, not only did she fail to analyze the existence of the source of pollution, but it made her even more confused.

"If it's not from the water source, where can it come from?" Lawrence began to circle around the room. "First of all, this kind of influence radiates the entire plain, so it is definitely not an inefficient method like artificial release or training certain animals to release pollution sources, because if the method of artificial release of pollution sources is also very easy to be destroyed It was found that there would be no traces like now."

"Could it be bees?" Nora suddenly asked, "I remember that many plants need to be pollinated in order to bear fruit, and the so-called cotton is actually the fruit of cotton. If that evil god is called the Zerg Prince, then he The power of the bee can completely manipulate the bees to complete the work of divine power pollution during pollination."

"Oh, of course not." Lawrence stepped forward and touched the doll's head and said, "Not all plants need insects for pollination. For example, flowers like cotton have no nectar and no smell, so Insects don't come. The pollination of this plant is mainly by the wind."

"Wind?" After hearing Lawrence's words, Nora suddenly remembered something and asked, "I remember that this area is mainly barren grassland or sandy land except for the irrigated farmland. Is it possible? It was caused by some winds blowing sand and dust polluted by divine power to this area."

"It is indeed possible, just wait for me." Lawrence said as he pulled out a weather report from a large pile of information, and then looked at it next to the sample report just now. After five or six minutes, he shook his head regretfully. "It shouldn't be the problem of the dust, because the degree of divine power pollution is very random and uniform throughout the land, and there is no obvious tendency for the windward side to be higher than the leeward side."

"Then besides the air, what else can spread the divine power pollution so evenly on this plain?" Nora showed a puzzled expression on her face. After all, although this cotton-planted plain is comparable to this country The area is small, but there are more than 1,000 square kilometers. It is about the same size as the Hanzhong Plain in Lawrence's previous life. It is definitely not a simple matter to evenly distribute the divine power pollution on such a large piece of land.

"If it's even—" Lawrence suddenly felt that something in his mind was touched by what the little doll said. After thinking quietly for a few minutes, he suddenly said to Nora. "I think I probably know what's going on. What you just said is correct. This kind of pollution is indeed carried by some dust, but it's not wind, but rain."

"Rain?" Nora thought about the size of this small plain located in the valley, and felt that Lawrence's judgment should be reasonable. Although the land of more than 1,000 square kilometers is not small, after a rain cloud gathers and the process is also Basically, the rainwater can be distributed evenly throughout the plain. If there is divine power pollution coming along with the rainwater, it will naturally be evenly distributed over the entire plain along with the precipitation.

"That's right, it's rain, but the core of the pollution doesn't come from the water vapor-rich rain clouds coming from the sea. It should be some dust that comes here along the atmospheric circulation from the inland direction." Lawrence explained carefully, "When it rains, the formation of raindrops requires condensation nuclei, and the polluted dust naturally becomes condensation nuclei and falls on the land with the rain."

Due to the confluence of two local air currents and the surrounding mountains in a river valley, the water vapor in a large number of clouds can also form rainfall on this land, which has laid a very good foundation for the formation of this pearl on the Gobi Desert. Base. Without these precipitations, this is a place that is no different from other arid canyons.

But now it is precisely because of this rainfall rule that the entire river valley area is polluted by the power of the evil god. Fortunately, because the god has fallen, it is only reflected in the rapid increase in value of the pests stimulated by those divine powers, without causing too many bad effects.

But if we let this trend continue, it is hard to say what changes will happen next. After all, as the pollution of the evil god's divine power continues to deepen, the impact of this pollution on the environment will also increase. One day, this place will become a barren land that is not suitable for intelligent creatures to live at all. So they also have to find out the source of pollution as soon as possible.

"In other words, the source of the divine power pollution this time is still some distance away." Lawrence's explanation made the puppet figure out one thing. "It's no wonder that the pollution brought by the sandstorm is not much. After all, the sand and dust brought by the sandstorm are larger and heavier. Compared with the dust in the rainwater, the distance from the pollution source should be much smaller."

"You're right." Lawrence poked the lazy book charm lying on the table with his finger and said, "Okay, it's time for you to get up and work. I have a very important document here that I need to help me Get it done in the shortest time, if you can get it done in the fastest time, I will give you two days off."

"What are you talking about, sir, are you on holiday?" The book charm who was lying on the table just now floated up immediately after hearing the word "holiday", and then quickly spun around Lawrence like a puppy, and then stretched out A few tentacles grabbed a stack of white paper and a bottle of ink from the table, stuffed them into their spherical body, and then spoke confidently. "Don't worry, I will get the paper out as quickly as possible."

After finishing speaking, Book Charm stretched out a tentacle to Lawrence and asked him to take it and stick it in the middle of his forehead. After Lawrence passed the summed up knowledge points to it, there was a crackling sound in Shumei's body, and soon, sheets of paper filled with words floated out of Shumei's body and landed on the table .

"Good job." Ten minutes later, Lawrence picked up the fully printed document and said after looking at it. Then he patted Shumei lightly and said, "I'll give you three days off, you can rest at the beach over there for three days.

"Great!" Hearing what Lawrence said, Shumei happily flew around him twice, and then rushed into the space door that Nora opened.

"We should get busy now." After watching the book charm leave, Lawrence looked at Nora and said, "The next task will be more difficult for us."
