After Linglong was discovered by Yifei, she hurriedly ran out of the tent, quickly changed her clothes, and dressed herself up as a man again.

Poor Yifei was tossed by her like this, and ended up with a big bag on his forehead.

"Childe, Childe......" At this moment, a familiar voice came, and Yifei looked up and saw that it was a brute cow.

Seeing the panicked appearance of the wild bull, Yifei couldn't help frowning: "What's the alarm?" ”

"Childe, we're digging water, we're digging."

Manniu was overjoyed, and after Yifei heard it, he was even more happy: "Really? That's great. Let's go, and I'll take it. Yi Fei said, and immediately followed the wild bull, preparing to reach the water source.

It was only early in the morning, less than four hours, or eight hours, before their water-seeking troops went out, and they didn't expect to find it so quickly.

"It was Lord Yuan and Li Chunfeng who found it." Manniu said.

"Oh? Is it? Sure enough, their skills are not covered! "Yifei is definitely right to let Yuan Tiangang and a few of his brothers go, Li Chunfeng's forgiveness technique is already perfect. And Yuan Tiangang's Tiangang technique is even better. One person observes the celestial phenomena, and the other blames the geography, but in a moment, the water source is locked.

As soon as he walked out of the tent, he met Linglong who was waiting outside: "I'm going too." ”

Yifei glanced at him with some complaint, and then nodded. When Linglong saw it, she jumped on the horse's back with a bang, and Xiao Hei had been conquered by her. Meng Yifei was very depressed.

"Oh yes, Childe, what's wrong with your head?" The brute asked blindly.

"Mosquito bitten."

"Oh......"

……

The three of them traveled late at night, but fortunately, Manniu was not a road idiot and could find the way he came. After walking for nearly two miles, they saw a large pile of fire.

"That's it, that's it." The brute bull pointed to the pile of fire, which was lit by Yuan Tiangang and them.

When Yi Fei saw it, he quickly ran over.

"Brother Meng, Brother Meng, ...... here" Yuan Tiangang's person also saw Yifei and hurriedly waved his hand. Finally, when Yifei arrived at the fire, he couldn't help but nod with satisfaction. It was a small grove, which must have been waterlogged all year round, and on the other side of it was the plain swamp, where there was water, but it was not drinkable.

Five hundred soldiers, within an hour, dug out a large pond with a radius of five meters, and at the bottom of the pond were the three springs, and they were bubbling with a steady stream of clear water. Although the water out of the water for the first time was mixed with impurities in the soil, Meng Yifei still held it and drank the turbid water.

"Ah, that's it, it's the taste, it's a little sweet, it's great." Yifei drank the water and couldn't help but feel very comfortable. The water he needed was finally found. All the soldiers gathered around this small pond and couldn't help but cheer. It's a long way from the camp, but that's not a problem at all.

"By the way, did you tell the general?" Yifei asked Yuan Tiangang.

"Someone has been sent, and it must be almost there."

"That's great, the general would be even happier if he saw this." Yifei is extremely satisfied at the moment, and he hasn't felt this excitement for a long time.

"Hey, Brother Yuan, why do you have so much black filth on your body?" At this moment, Yifei saw that the bodies of Yuan Tiangang and the others were full of black stains, a piece of black pressing, digging water would not be like this, and the soil was also yellow!

After hearing this, Yuan Tiangang's person couldn't help but shake his head: "Don't say it, it's really unlucky to say it." We dug two places, and the first one was all black water, greasy and pungent that felt like a place where corpses were decomposing. The things on this body are made of the black water.

"Blackwater?" Yi Fei was stunned for a moment, and then he walked to Yuan Tiangang's side and sniffed the dirty cuffs.

"What is this?" With a flash of white light in his head, Yifei was shocked, and said incredulously, "This, this is oil?" Yifei was taken aback.

And after Yuan Tiangang and others heard this, they were also stunned: "Oil? What is Oil? ”

Yifei didn't have time to explain to them, but immediately asked them to take him to that place.

"Brother Yuan, where is the first place to dig a well, take me there." He can't wait, yes, it's oil, definitely.

Yifei's mood is even more excited now, he is almost unable to suppress it, and hurriedly urges him.

Seeing that Yifei was so anxious, Yuan Tiangang immediately took him to the first place where he dug water.

The place was not far from the water source, and it was only a hill away. This is a depression, giving people the feeling of not pulling out a hair, because there is not a single big tree growing, but after Meng Yifei saw it, he immediately jumped off the horse and rushed directly to the pit that Yuan Tiangang and they had just dug.

"Yes, yes, oil, really oil." Yifei almost jumped in. Oil, this is oil. It was more exciting for him than digging into the water.

He dipped a little in his hand, watching the viscous oil slowly drip down his fingertips, his eyes open more than ever, and he felt like he was about to drink the oil.

I didn't expect that on the land of China, there was a place where you could dig oil with any hoe.

"Hahahaha...... Hahahaha......" Yifei knelt on the edge of the oil pit and laughed maniacally. Yuan Tiangang and the others behind him thought that Meng Yifei was crazy, and no one dared to approach for a while.

But Yi Fei was not crazy, on the contrary, he was very sober, just now, at least twenty or thirty new plans flashed in his mind, new plans made through oil.

It's open-pit oil, it's not only natural, but it's also easy to collect. The role of these fossil fuels is staggering. It can be used as fuel, lubricant, asphalt, solvent, petroleum coke, petrochemical industry, high-temperature fuel......

Its usefulness is absolutely unparalleled, especially in times of war, and the magic of oil can be applied anywhere.

Siege, plunder, burn grain......

Even in that moment just now, Yifei thought of the most important role of oil. Yifei wants to use it, as long as it has it, any problem can be solved.

The advent of oil is almost equivalent to the early arrival of the machine age. It can make oil, steel, glass, machines, and even firearms......

Of course, oil alone is not enough, but with oil, is it not easy to get it? In ancient times, there were so many skilled craftsmen that even some extremely sophisticated instruments could be made, if they were given oil, steel, a new material, a new knowledge, would they still be afraid that they would not be able to do it?

Yifei was excited, and it made people wild in their hearts just thinking about it. Plans, countless plans swirling in his head, oil is an absolute treasure.

"Brother Yuan, didn't you bring more than five hundred wooden barrels to hold water?" Yifei turned around with a smile and asked Yuan Tiangang, who was ten meters away.

Yuan Tiangang was intimidated by Yifei's weird smile, and hurriedly nodded: "Well, I brought a bucket, and after the water is clean, we are going to fetch water and go back." ”

"Well, can you leave me ten barrels?" Yifei's weird smile at the moment was indeed a little confusing, but Yuan Tiangang had no reason to refuse.

"Yes, yes!"

"Then thank you, leave me another carriage, and you can all go back except for the brute! Isn't the general coming? Go and help! ”

Yifei has always had that kind of smile, the corners of his mouth are about to crack, I don't know what kind of joy it is, it feels like a smile after some conspiracy succeeds. Yuan Tiangang and the others, who were watching, were chilled, and hurriedly nodded and left.

Yifei turned his head again and looked at the big pit of oil in front of him, and he involuntarily laughed again: "Hahahaha...... Hahahaha......"

Yuan Tiangang, who had just climbed the mountain, had a cold back and left in a hurry. (The first war in this book is coming.,I want to hit the list tomorrow.,Everyone.,Help.,Thank you.,I'll try to update!) ）
