Guo Xin's mind was in a mess, and before he could figure out what it meant, Xu Wenshan shouted at the little guy to come and go home with Guo Xin and go to his house to carry food.

Guo Xin returned home in a daze, measured the surplus grain in a daze, and watched the Xu family empty the food at home in a daze. When I was sitting at home, I hadn't figured out what contract I had signed with Xu Wenshan.

He called his smartest fourth son over and asked, "Four dogs, did I make or lose money in this business today?" ”

After the fourth son did the math, he said: "In terms of money and goods, my family's field produced 5 buckets of grain per mu last year, if it is like this every year, the interest that his family wants is 2 yuan, that is to say, our family borrowed 20 yuan, but only need to repay 2 yuan of interest, and I have earned a lot." At the same time, he bought my family's surplus grain at a price higher than the market price, and my family still made money. ”

The Guo family had 56 buckets of surplus grain, which was sold to the Xu family at 42 wen per bucket, and the money from the sale was naturally written by Xu Wenshan on the "shopping book", and now the Guo family has 22 yuan and 352 wen money in the "shopping book".

Guo Xin thought about it, it was true, and said: "But my family's surplus food is gone, and I haven't seen the money?" ”

The fourth son said: "But in the next five years of my family, the Xu family will have to take care of the food and meat that my family eats, isn't it good?" ”

Guo Xin was relieved, and when he went to bed at night, he suddenly thought: "The son of the Xu family bought my family's grain according to 42 Wen per bucket, and my family can buy his family's grain according to 40 Wen per bucket, so I made a net profit of 112 Wen, and at the same time, the Xu family lent me 20 yuan, 20 yuan is enough to buy ten acres of land, and ten acres of land can produce 50 buckets of grain per year, that is, 2 yuan, and their family only needs a little interest, which means that my family still earns a lot of money...... But where does the money go? ”

Thinking about it, he entered the realm of mystery.

……

After settling the Guo family, the dead soldiers of the Xu family all looked at Xu Wenshan with reverent eyes. When Xu Wenshan saw them off, some of the dead soldiers bowed deeply to Xu Wenshan.

These people are Xu Changshui's dead soldiers, not Xu Wenshan's dead soldiers, if Xu Changshui dies one day, they will also wipe their necks and commit suicide. However, this does not prevent them from having respect for the next generation of family heads.

Don't get me wrong, they wipe their necks not because of how loyal they are, but because there is no one to support them.

These "dead soldiers" were fed and fed well in the Xu family, and they had long lost their willingness and ability to work. If you have a little willingness to work, you will not take refuge in the Xu family as a dead soldier.

In Xu Changshui's eyes, they are just tools that can speak, and they don't even have reproductive rights. Xu Wenshan naturally looked down on the dead soldiers produced under this deformed system, let alone the impulse to inherit and dominate them.

For the time being, the Guo family has stabilized the Guo family with the "shopping book" strategy, which can ensure that the Guo family will not make waves again in the short term. When the Guo family wakes up, they will definitely regret being a white wolf by the Xu family's empty gloves, and they will definitely make trouble again, but they should have come back by then.

It's time to go.

However, this time, Xu Wenshan's target is not the county government, but the water source.

Finding the water source was the last thing Xu Wenshan had to do before leaving Luhegou. This is quite important.

Luhegou is surrounded by mountains, and it is not easy to find water sources in the mountains. But after becoming a demon cultivator, Xu Wenshan's speed has been greatly improved, and he and Lu Ze jumped on the treetops, climbed between the cliffs and cliffs, and while walking, they drew a sketch of the landform around Luhegou in their hearts.

From the topography point of view, the general southwest is high, the northeast is low, if you want to build an aqueduct, you should start from the southwest.

The first day's search was fruitless, and the next day, the two encountered a high mountain, and Xu Wenshan found large chunks of basalt at the foot of the mountain.

As a standard liberal arts student, basalt is a typical rock that is naturally fresh in my memory. Although basalt is not a very precious stone, its existence shows that the mountain is a volcano.

Basalt is the same as the granite used by Shikazawa to make stone armor, both are magmatic rocks, the difference is that granite is an intrusive rock and basalt is an ejecta rock. Basalt is formed by the condensation of magma that erupts from a volcanic crater.

The surface of the ground in front of you has been weathered for many years, and there are no signs of eruptions at all, so it is impossible to speculate how long the last eruption was. Xu Wenshan decided to go up the mountain with Lu Ze to have a look.

As a result, the mountain was even higher than they had imagined, and the two of them climbed all the way from morning to afternoon, and they never saw the top of the mountain.

As the altitude increases, the temperature is noticeably getting lower and lower. Xu Wenshan speculated that the temperature has dropped by 5 or 6 degrees, which means that the relative height from the foot of the mountain to here is close to a thousand meters.

After climbing a steep cliff, the two finally reached the top of the mountain. The vegetation here is dense with coniferous forests and some low grasses. When Xu Wenshan saw these plants, he screamed excitedly and ran forward.

Lu Ze was a little confused, and also ran after him. The two of them climbed over a small hill, and when they stood at the top of this high mountain, the scenery in front of them invaded the whole world as if it had crashed into view.

On the top of this sky-high mountain, there is actually a lake.

The blue water of the lake reflected the clouds in the sky, and there was not a trace of ripples on the surface of the lake, like a mirror, as if some god had broken the sky and settled here.

Xu Wenshan couldn't suppress his excitement and rushed down the hillside, Lu Ze looked at the strange scene in front of him in a daze for a while, and also cautiously went down the hillside. When he arrived at the lake, Xu Wenshan had already taken off his clothes and jumped into the lake.

Ever since he crossed to Luhegou, he hadn't taken a bath, and he had almost forgotten what it was like to wash his skin with cool water!

Xu Wenshan buried his face in the lake, raised his head again, and looked at the clear sky, not knowing whether it was lake water or tears on his face.

This lake is the second gift he received after coming to another world, in addition to Luze.

For various reasons, the mouth of the funnel into which the lake seeped into the ground was blocked, and such a large karst lake was formed in the crater, which would have been impossible without a miraculous coincidence. Just now, Xu Wenshan dived underwater to take a look, and the lake area was 300 square kilometers. According to his estimates, the lake should have a storage capacity of more than 200 million cubic meters.

On top of that, it's a freshwater lake. As long as this lake can be brought in, ten more deer and crane ditches can afford to raise. This is why Xu Wenshan is excited.

"You can also come down and bubble, it's very comfortable." Xu Wenshan waved at Lu Ze on the shore.

Shikazawa shook his head nervously and blushed.

Xu Wenshan then remembered that he stripped naked in front of the little girl, which was very indecent.

He felt in his heart that the two had already shared the same bed, and had concluded a master-slave relationship between life and death, and they should be able to be more open in this regard. It's just that the Lu Ze in front of him seems to be much more productive than the Lu Ze 2 years ago, and he doesn't call himself a "Xianggong" anymore, nor does he call himself a "slave family", and he always keeps a distance from himself.

may be because of their own behavior back then, which made them distant.

However, Lu Ze's next sentence immediately made him realize that he would be wrong.

"I ...... I don't know how to water. Shikazawa's face turned even redder.

Understandable. As a little demon in a ravine, it's normal to not be able to swim.

Xu Wenshan comforted: "It doesn't matter, it's easy to learn, my father threw me into the pool when I was a child, and I just picked it up myself." ”

Lu Ze still shook his head, and took two steps back in fear.

Xu Wenshan then thought that she was a mud puppet, and it was difficult for the mud bodhisattva to cross the river, so of course she would be afraid of water.

It's just that since she has cultivated her debut body, she shouldn't be afraid of being soaked away anymore, probably because of her nature, she is still afraid of water, it's really pitiful.

Looking at the thin and small Lu Ze in front of him, Xu Wenshan suddenly overflowed with fatherly love, went ashore to hug Lu Ze, and threw her into the water.

Lu Ze was taken aback by this sudden impact, and her reaction was shocking, and after fluttering twice, she sank directly to the bottom.

Xu Wenshan was still on the shore, stupidly waiting for her to collapse. The place where he threw her down was a shoal, and Lu Ze could show his face when he stood up, but he didn't expect Lu Ze to sink to the bottom.

He secretly screamed that it was not good, jumped down and scooped up Lu Ze.

……

A bonfire was lit in the cave and some clothes were hung on the shelves. Xu Wenshan stayed next to Lu Ze, and Lu Ze fell asleep.

No one would believe that a monster whose strength is equivalent to that of the human foundation building period in the Yin Refining Period would actually faint because of falling into the water.

"There's a demonic aura." Lu Ze woke up, and suddenly came to such a sentence.

Xu Wenshan didn't speak, straightened up and looked around, and said, "I didn't find it." ”

Lu Ze said: "The strength is probably in the middle stage of Yin refining, and it is also of the earth attribute. ”

Xu Wenshan nodded, he only had the early stage of forging his body, and if the monster in the Yin Refining Period deliberately hid his demonic energy, he would not be able to feel it.

"It's in the depths of this cave, do you want to go and see it?" Shikazawa asked.

Xu Wenshan nodded. Now is the time to expand your strength, and it is beneficial to be able to contract a few more yokai, and if the opponent is strong, you can still run.

Lu Ze put on his clothes, Xu Wenshan consciously turned around, and after Lu Ze was dressed, the two walked to the depths of the cave together.

The cave is pitch black, the ground is slippery, and it is steep downward, but fortunately, after becoming a demon cultivator, the night vision ability has been strengthened, otherwise it will definitely fall into a mess.

I don't know how long I walked, Lu Ze stopped and said, "This cave is a little strange. ”

Xu Wenshan stopped and asked, "What's wrong?" ”

"There is always a faint demonic aura in this cave."

This cave was found on a mountain, Xu Wenshan didn't think much about it at that time, and went in directly, now that I think about it, it is quite strange that there is a cave here.

Xu Wenshan touched the wall in the cave, but the tentacles were soft and slippery, and several string-like things writhed under his palm.

There was a sharp pain in his palm, Xu Wenshan put his palm in front of his eyes, and found that the liquid he had rubbed on the wall just now was corroding his palm.

Only then did he see that there were many tiny holes in the wall, and countless earthworms poked their heads out of the holes and writhed in the air!

Xu Wenshan suddenly thought, this narrow and winding cave, these inner walls secreting viscous liquid, aren't they like a intestine?

Xu Wenshan grabbed Lu Ze and said, "Wait a minute." ”

Lu Ze noticed Xu Wenshan's strange appearance and said, "What's wrong?" ”

Xu Wenshan said: "Be careful not to touch the wall. ”

The two of them stopped, looked intently, and the scene in front of them became clearer and clearer, the inner wall of the stone cave was full of large and small holes, and countless earthworms were drilling around in these holes, and some half of their bodies were exposed, waving awkwardly, looking extremely disgusting.

These earthworms are low-level companion spirits of youkai. Many youkai can breed offspring and let the queen fight in their place, and this monster in front of you is obviously the same.

The liquid on Xu Wenshan's palm was constantly corroding the skin, and there were bursts of pain. Xu Wenshan looked down at the palm of his hand, the skin in the palm had festered, and the liquid was like hydrochloric acid, burning his muscles white.

After becoming a demon cultivator, he can use his demon power to quickly heal his wounds, but these places corroded by venom can never heal, and if these venoms are not eliminated, the palm of his hand cannot heal.

It only took one touch to get stained with such a troublesome venom, it seems that the strength of this monster is indeed good, and at the same time, it is not good to himself.

Xu Wenshan commanded Lu Zedao: "Try it with flying sand, can you cut off these earthworms." ”

Shikazawa nodded, and used the Flying Sand Technique to condense a piece of gravel as sharp as a blade, and then pushed it on these earthworms like an imperial sword, and the first two earthworms that poked out of the hole were cut off like vegetables, but when they reached the seventeenth or eighth, the stone chips condensed by the Flying Sand Technique fell to the ground and could not be used, and the sharp edges of the stone flakes had been corroded into pits.

The half-cut earthworms that had been cut down to the ground writhed on the ground, and soon turned into a new earthworm and disappeared into the ground.

Xu Wenshan nodded, this can kill earthworms, but it is too troublesome.

And the trouble is the venom on the hands, how to remove it is a problem.

Wherever this venom touches, it is corrupted. If you rub your palms on your body, you will soon be stained with venom. If it is wiped with sand and gravel, it will enlarge the wound and allow the venom to enter the bloodstream.

He suddenly thought of a solution. He also had a few diamonds on him.

Diamond is a solid single crystal made of four carbon atoms that even aqua regia cannot corrode away. Dissolving diamonds is cumbersome and has to be done under extremely demanding conditions.

Xu Wenshan had already "refined" those diamonds in the way of monsters and stored them in his body. He used the stone skin technique to directly "grow" the diamond particles from the wound on the palm, and soon, the palm of the hand was covered with a layer of transparent diamond as if wearing a layer of gloves. The venom was "squeezed" out by the diamond particles and dripped on the ground drop by drop.

After draining the venom without a trickle, Xu Wenshan finally breathed a sigh of relief. He divided the diamond into a finger-sized mass and gave it to Lu Ze, and said, "Refine it, and then use it to use the Flying Sand Technique." ”

Ordinary stones will be corroded by the body cavity fluids of these earthworms, but diamonds will not.

As he said, Shikazawa condensed these diamonds into sharp stone flakes, and when he used the flying sand technique again, this time he was even more handy, cutting the earthworms like wheat. The two of them moved forward while clearing earthworms, and they were very proficient.

The slaughter of earthworms seemed to kill the owners of these little monsters, and the stone cave began to shake, Xu Wenshan and Lu Ze grabbed each other to prevent them from falling.

"Boom" There was a loud noise, a giant beast rushed out from the depths of the cave, like a train crashed into Xu Wenshan, Xu Wenshan held the monster's head with both hands, and was pushed off the ground by the monster, Lu Ze also hugged Xu Wenshan, and the two flew out of the stone cave.

When he arrived outside the cave, Xu Wenshan saw clearly what kind of monster this was, it turned out to be an earth dragon.

The earth dragon is the earthworm that has become the essence. This kind of monster is only a mere yellow level intermediate level, and it is one level weaker than the wine worm. It is recorded in the Book of Prophecy that the earth dragon is not aggressive, and its self-protection ability is also insufficient, and it often becomes food for other monsters, and the only advantage is that it has a long life span and strong reproductive ability.

Unexpectedly, it was this yellow-level earth dragon that cultivated into such a huge behemoth.

The earth dragon poked its head out of the cave, and with a single head, it was the size of two small bungalows, not to mention the part of the cave.

It's not easy to deal with such a large youkai.

"You, kill ...... Child, dead...... Die! The dragon rumbled loudly, barely speaking, but only fragmented sentences.

But even a fragmented sentence can express its anger.

"Kill!"

The earth dragon stretched and shrank, and more bodies emerged from the stone cave, and its whole head hit the ground like a whip, and there was a loud "boom", and half of the mountain was shaken.

However, the earth dragon had no eyesight and was not very dexterous, so Xu Wenshan and Lu Ze easily dodged this earth-shattering blow.

The body of the earth dragon lay on the ground, and the surrounding vegetation was stained with its body cavity fluid, and immediately withered under the corrosive effect of the venom.

After all, the monsters in the middle stage of Yin refining cannot be underestimated. If you rashly beckoned directly to this monster just now, it is estimated that your body will be corroded.

Xu Wenshan used the "Diamond Star Fist", his two hands condensed diamonds, and an arrow stepped forward, taking advantage of the fact that the earth dragon had not fully raised its body, and punched it to the head.

The part of the earth dragon that was hit shattered like a rock, it wailed in pain, Xu Wenshan's punch was specially lighter, otherwise his entire arm would have penetrated the skin of the earth dragon and entered the body of the earth dragon.

Lu Ze directly used the flying sand technique to condense a diamond blade, drilled into the body of the earth dragon like cutting tofu, and then drilled out from the other end.

Although the earth dragon had rough skin and thick flesh, it couldn't withstand the continuous attacks of the two, and soon fell to the ground with a bang.

Xu Wenshan kicked the dragon and said, "Do you admit defeat?" ”

The earth dragon rumbled, "Kid......"

"Come on, aren't you earthworms? Your children will soon be restored. ”

……

Under Xu Wenshan's coercion and temptation, the earth dragon succumbed and became Xu Wenshan's second servant.

This earth dragon is simple-minded and huge, so it is not suitable to take with him, so Xu Wenshan simply let it stay here and manage the cave well, if Xu Wenshan wants to flee one day, he will hide here.

However, Xu Wenshan left it with one task: to dig a ditch.

The huge body of the earth dragon and the ultra-efficient drilling method just saved him a lot of effort in building the aqueduct.

In the next two days, Xu Wenshan took the earth dragon over the mountains and mountains, touched the mountains along the crater lake to the Luhe ditch, and left the task for the earth dragon is to cut the mountain if there is a mountain, and open a culvert if the mountain is not cut, in short, the line between the lake and the Luhe ditch should be dug through, so that the canal can be opened to divert water in the future.

Dilong said it was a good job, but it would take time — probably months. Xu Wenshan said that he was not in a hurry, let it be done slowly and do it well.

After arranging these matters, the last thing in Luhegou was also completed, and he decided to leave Luhegou.
