"This is the reservoir!" Lu Rui drew the prototype of the reservoir in later generations, and sat next to it to annotate, of course, this is a simplified version, the reservoir must not have modern functions such as power generation, mainly water storage and flood discharge.

"My lord is really whimsical, this reservoir has the function of a flood channel, and the effect of a reservoir, it is really a great project of agriculture, but my lord, this project is so depleted, I am afraid that it is not a year's work, and the bricks and stones required are a huge project." Mao Jie was Cao Cao's internal strategist, and he immediately analyzed the pros and cons of the reservoir.

"Filial piety is not a loss is the strategist that Lord Sikong relies on, although this reservoir takes a huge amount of time, but the reservoir has a big practice, a small practice. We can build smaller reservoirs now and see how it goes. Lu Rui thought to himself, it will definitely take several years or even ten years to create the scale of the reservoir in the future, but to build a large reservoir, one year is enough!

"Your Excellency is wise, we will immediately sort out the relevant information, find a suitable place to build a reservoir, and report it to Lord Sikong."

"What Xiaoxian said is reasonable, and now I have found people who are familiar with the geographical environment within 300 miles of Xudu, and asked them where the water source is more abundant, and then I will go to the field to investigate and see if it is suitable for building a reservoir." Lu Rui was also unambiguous, and directly gave orders to the two.

"Yes, sir!" Mao Jie and Zao Yi arched their hands and retreated.

Three days later, the two determined a location and took Lu Rui there. Due to the long distance, in order to facilitate the trip, Lu Rui only brought Dian Wei and Murong Ping, as well as four monks, plus Shi A's thirty assassins, after all, this is a geographical survey, not to visit the mountains and rivers, for the sake of speed, he does not bring a large army.

"Master Hou only brings these people, isn't it safe?" Arriving at a resting dense forest, Mao Jie asked worriedly, after all, the vicinity of Xudu was not very peaceful. Out of Xudu a hundred miles, Xudu's army is basically uncontrollable, after all, there are not many troops guarding Xudu now, here is basically the Yellow Turban Liukou, and there are all kinds of chaotic soldiers' gathering places, the number is not large, dozens of people in groups, often robbing weak teams.

"Xiaoxian don't have to worry, the people in Benhou are all elite, just a rogue guy, don't worry." Lu Rui also attaches great importance to his own safety, and the small group of rogues in this vicinity is definitely not his elite opponent, even if he encounters a relatively large group of rogues, the four monks will go up to capture the thief and capture the king first.

"Yes, Master Hou!" Seeing that Lu Rui was full of confidence, Mao Jie was no longer being pursued, after all, Lu Rui had followed Cao Cao since he was a child, and his safety awareness was definitely better than himself!

After a day's journey, Lu Rui and the others finally arrived in front of a tall mountain peak, saying that this mountain peak is big? For Lu Rui in his previous life, he grew up in the mountains and mountains in the south, this mountain is a small peak, there is nothing unusual, but for the rest of the people, hehe, a big mountain!

"What a majestic mountain!" Zao had never seen such a tall mountain, and he couldn't help but exclaim.

"Xiaoxian, that's what you're talking about?" Lu Rui took a look, compared to the plain area, this is a big mountain, it should meet its own requirements, the so-called high mountains and flowing water!

"Yes, my lord, please explain it to you carefully." After speaking, from the ranks, a woodcutter walked out.

"The villain Wang Dashi has seen an adult!"

"My lord, this is a guy in our army, who is responsible for cutting wood everywhere, and is very familiar with the geographical environment near Xudu."

"Okay, Uncle Wang, tell me about the situation here."

"Yes, sir!" Uncle Wang? Hearing Lu Rui call himself uncle, he was full of joy.

"Lord Huiyu, the name of this place is Songshan, which belongs to the Funiu Mountain system, and Songshan Mountain is high." Later, Wang Dashi talked about the situation in Songshan and introduced it to Lu Rui.

This is Songshan? However, according to the itinerary, this is definitely not Shaomuro Mountain, but it should be a branch of Songshan Mountain.

"Is there a big water source here?"

"Yes, Master Hou! There is a large pond not far ahead, and the water source is abundant! There is water all year round. Wang Dashi pointed to the platform not far away.

"Okay, let's take a look!" Lu Rui and his entourage soon arrived at the platform that Wang Dashi said.

It is a large pool with a waterfall flowing down from it, and the water flow is relatively gentle. Lu Rui said: "Filial piety first test the depth!" ”

"Yes, Master Hou!" Mao Jie took out a piece of hemp rope for measuring the depth, then tied a stone and threw it into the pool, allowing the stone to sink to the bottom of the pool.

"Master Hou, I have tested it, this pool is about three zhang deep!"

"Sanzhang?" Lu Rui touched his chin, and began to silently calculate in his heart, what is the shape of the pool below, he doesn't know, according to the regular square calculation, the water source seems to be a little less.

"Uncle Wang, besides, are there any other water sources nearby?" Lu Rui looked at Wang Dashi suspiciously.

"My lord, no."

"What about above?" Lu Rui pointed to the top of the water flow, according to geographical knowledge, this pool is already close to the foot of the mountain, there should be such a pool on the mountainside, and the water source connected to the underground river should be more abundant.

"This? My lord, there is no mountain road carved on it, and there are many wild beasts on it, and the villain does not dare to go up and does not explore carefully. ”

"Beasts?" Dian Wei clicked a few times and solved the problem.

"Evil comes, take ten people to open the way, go to the top to find water."

"Yes, Master Hou!"

"Let's go down there and set up camp, it's not a day's work to open the way!" Ancient open roads are not modern, especially such unexplored mountain roads.

"Yes, sir!" Lu Rui took the rest of the people to camp at the foot of the mountain, and Dian Wei led the people to open the way on the mountain.

After a busy night's work, Dian Wei ran down from the mountain and said, "Master Hou, I found a bigger pool!" ”

"Okay, let's take a look!" Lu Rui took everyone to climb the newly opened mountain road of Dian Wei, the so-called newly opened mountain road, which is a simple mountain road, a simple road with long wood erected on the mountain rocks.

Soon, Lu Rui and the others arrived at the pool that Dian Wei was referring to. Lu Rui saw that there were many pools in this pool, and the waterfall above it was also bigger than the one at the foot of the mountain, and at a glance, the water source was absolutely sufficient!

"Xiaoxian, test the depth!"

"Yes, sir!"

Soon, the depth of the hair scale was tested, about more than 100 zhang!

When Lu Rui heard this, he was stunned for a moment, more than a hundred zhang? It seems that this must be an underground river connecting this mountain system, and the water source is abundant, hehe, this is easy to do.

"Filial piety, Jimin, this is our reservoir!" Lu Rui smiled and said to Mao Jie, how can you not use a natural reservoir?

"What do you mean, my lord, that this is a natural reservoir that stores water for farming?" Zao is only an expert, and he immediately understood what Lu Rui meant.

"Yes, Xiaoxian once said that building a reservoir requires a lot of masonry, and now the heaven-sent reservoir, how can we not use it?" Lu Rui looked at Mao Jiejie with a grin.

"Your Excellency is wise, this place is indeed a heaven-sent reservoir, but there is something unclear about the lower officials, please give me advice."

"Does Xiaoxian think that this place is far away from Xudu, how to lead water to Xudu?"

"Exactly, my lord, this place is about two hundred miles away from Xudu, and if you build a ditch, I'm afraid it will be a huge project."

"Xiaoxian, why do you want to lead water to Xudu, why don't you lead Tuntian here?"

"This?" Mao Jie touched his head and thought about it.

"Is it difficult for filial piety to think that the soil here is not suitable for planting?"

"Nope! My lord, the soil quality here is better than that of Xudu! ”

"I see!" Mao Jie suddenly realized, arched his hand and said: "My lord is really powerful, our army will lead Tuntian here, there is no need to worry about the water problem, our army will get a bumper harvest this year!" ”

"Why is Jimin silent?" Lu Rui saw Zao Yi who was pondering on the side, and asked suspiciously, is there something wrong with his plan?

"My lord, my subordinates have a concern, even if our army moves the tuntian here, and then digs a river channel and diverts water for irrigation, but this terrain is higher than the surrounding areas, if the water level sinks, how to pump water up may be a problem, and this place is steep, only afraid of a large amount of water, we can only look at the water and sigh."

It is worthy of being a jujube, and even the water pressure problem and the pumping problem have been thought about, but this is not a problem for Lu Rui!

"Haha, Captain Zao doesn't know, Ma Ke on the Hou Ye's Mansion in Fan County is a talent, his improved overturn is small and light, my family's full can go to pump water, is this a problem!" Dian Wei looked at Zao Yi with a smile on the side.

"What? Is there such a thing in the world? Zao only looked at Lu Rui in disbelief.

"Jimin don't worry, this rollover has been widely used in Fan County, and it will open Jimin's eyes when the time comes." Ma Jun's overturn is first-class, changing the entire Cao Wei's agriculture, Lu Rui gave Ma Jun the greatest support, and now, there are many inventions!

"Jimin doesn't have to doubt that he has seen this thing in Fan County, compared to the traditional rollover, it is small and lightweight, and pumping water here is not a problem." As an internal strategist, Mao Jie, who has been to Fan County, certainly knows the role of overturning.

"In that case, it's just a matter of worrying."

"Okay, since that's the case, the two of you will return to Xudu with me and report to Lord Sikong." It's still not March yet, if it does, come directly here to Tuntian!

"Yes, sir!" Lu Rui and his entourage got on their horses and headed to Xudu.

"Be careful, sir!" As soon as Lu Rui and his party arrived in a dense forest, Dian Wei stopped everyone.

Murderous? There is a faint murderous aura! Seeing that Lu Rui and the others were not leaving, the ambush people immediately rushed out, Lu Rui looked at it and smiled, it turned out to be the group of Kou Yellow Turbans?

"Hand over your belongings and food! Or I'll kill you! I saw a small leader, holding a big knife, pointing at Lu Rui and shouting. There was also a man dressed as a scribe next to him, who seemed to be the leader of the group!

"Hmph, evil, cut it all down for me!" The little yellow turban thief is still posing in front of Lao Tzu?

"Yes!" Dian Wei received the order and rushed out with his halberds in hand, and more than a dozen assassins also drew their long swords and rushed over.

Dozens of yellow turbans were no match for Dian Wei and the others at all, and they were quickly killed, and when the scribe saw this, he was stunned for a moment, and then hurriedly fled.

"The thief is on the run!" Dian Wei jumped in front of the scribe.

With a bang, yellow smoke rose from the scribe's body, and then with a whoosh, it disappeared, and the yellow smoke drifted by, and a wooden sign fell.

Dian Wei was stunned, and everyone was also stunned.

"Magician! Ancient magicians, there are ancient magicians here! Lu Rui immediately reacted, those yellow smokes should be phosphorus powder!

"Master Hou, this is left on that person!" Dian Wei picked up the wooden card and handed it to Lu Rui.

There are two words written on it: Sima! ”
