Li Yunfei and his entourage stayed in the Heishui River for a long time, and of course they stayed very well, because they needed help to control the pollution of the black oil. Of course, I also want to rest and relax, in the past few years, I have always eaten and drunk, and from time to time I have been attacked by demons and monsters, and there are many disasters, and life is really not good.

So this time there is a rare reasonable reason, of course, to rest for some time, and even gave a few apprentices a long vacation, even Zhu Bajie took the opportunity to go back to Gao Laozhuang once, that guy also asked for three Nine Zhuan Dan from Li Yunfei's hands, I think that with this elixir as a gift to bring back, his old man will also look at him differently......

In the days when I was helping to control pollution in the River God Mansion, I was like a king, and there were always a lot of shrimp soldiers and crabs when I went out, and that Bai Lier was also by her side all day long, busy like a secretary.

When someone politely calls the holy monk, if there is no one, he will do it in his arms affectionately called his husband, at first Li Yunfei was indeed a little unaccustomed, no matter how to say that he has been a monk for more than 20 years after coming to this world, suddenly this feels weird, but after a long time, he will get used to it, and even enjoy her very much like a bird.

It is said that the cave with black oil is several kilometers deep, and it is said that the magic bead was dug out here, as for how the dragon knew that the magic bead could be dug here, it is unknown, anyway, he dug it.

In fact, the black oil that came out of this hole** also carried a trace of demonic energy, but the amount was very small, and it only needed to be heated and separated by high temperature, but it would be easily absorbed and digested by the laws of this world, and it would not leave any hidden dangers, this thing seemed a little weird, but Li Yunfei didn't care too much.

As for the strange magic bead, Li Yunfei has also carefully analyzed it these days, but he can't figure out what kind of material it is, it is somewhat incompatible with this world, and the demonic qi is also very different from the common demonic qi before, and it is very likely to be a foreign object.

The pollution power project of the Heishui River is quite huge, but the progress of the work is quite fast, no matter how it is said that this is also a mythical world, and Li Yunfei is still a formation master, and many equipment can be replaced by formations.

Under the guidance of Li Yunfei, those shrimp soldiers and crabs set up a large formation at the exit of the cave, and under the action of the formation mana field, all the leaked crude oil was gathered into a large pipe, and the collected crude oil was sent to a large storage tank for storage. Then, after the initial heating and separation, several materials such as gasoline and diesel are obtained, although this is a mythical world, but these fuels can still be exchanged for a lot of money.

Speaking of this mythical world, the immortals in the sky are actually almost no different from the mortal world in many things, such as most of the lamps are still lit with oil. Although there are also magic weapon lamps and lanterns driven by mana, those lamps are too precious, and ordinary little immortals really can't afford to use them. For example, this Black Water River God Mansion uses a fish paste lamp, although it is durable, but the brightness is really not good......

……

It's late at night, Li Yunfei is still under an oil lamp, deducing some Mithril formations, Bai Lier has been sitting quietly on the side, Li Yunfei is studying the formation, but she is studying Li Yunfei, but after studying for more than ten days, Li Yunfei is still a mystery to her.

“…… What is Lil looking at? Feeling the hot gaze, Li Yunfei finally couldn't help but ask.

"Husband, it's late at night!"

"Li'er is sleepy, then let's go rest first, I still have to study some formations!"

“…… Can I sleep with the slave family tonight? Bai Lier lowered her head and said timidly.

"This ...... That's okay, it's just ......" Li Yunfei has always insisted, striving to do other things after completing the task of learning from the scriptures.

"The slave family understands that the husband only needs to talk to the slave family!"

“…… It's hard for you. In fact, Li Yunfei himself is even more difficult, if he doesn't have some concerns, I'm afraid that if I really fall in love with this Bai Lier, then I won't be able to complete the great cause of learning from the experience, what was it last time, instead of enduring it at the last moment.

"No, husband, come on." Bai Lier looked excited.

In fact, she is even more obsessed with sleeping with Li Yunfei, as for other things, it is dispensable, because Li Yunfei has a very special aura on his body, which can make people feel very warm and comfortable when they stay around......

“…… Husband, have you slept? I didn't notice any movement from Li Yunfei for a long time, so Bai Lier asked in a low voice.

"Nothing?"

"What is the husband thinking?"

"Well, didn't think anything of it." Li Yunfei really didn't dare to think about it.

“…… Husband, how did you know that the black oil could separate this gasoline and diesel? Bai Lier asked without words.

"There are mountains in the south of the county, and the spring water comes out of the stone, which is as big as that, and the burning is extremely bright, and it is not edible. The county people call it stone paint...... "Li Yunfei said a record in an ancient book, but before he finished speaking, he heard Bai Lier's even breathing, and he fell asleep after listening to it like this, which shows how boring he is?

She sleeps peacefully, but Li Yunfei is uncomfortable, men and women are indeed very different, as a normal man, it is really difficult to control his lower body many times.

Especially when holding a fragrant beauty and this beauty still wraps the jade legs around herself, there will always be many exciting pictures in your mind, as a traverser, in the context of the Internet in later generations, it is a normal man who has lived many love action movies, so his mind is full of those dirty pictures. The only way is to deduce those incomparably mysterious Heaven and Earth Five Elements Arrays in the Sea of Knowledge, as long as the spiritual power is exhausted, you can always fall asleep.

Deducing the Five Elements Formation in the Sea of Knowledge, it took more than two hours to exhaust his mental power and fall asleep, but after falling asleep, he had a spring dream, and he seemed to be a few powerful young heroes in the dream, or a fairy hero, who could soar through the clouds and fog, and even had an island owner, and the island was full of young and beautiful women.

The afterglow of the sunset is still in the sky, reflecting the red glow, and he is standing in front of the window looking into the distance, this is a very elegant picture, but there is a choppy girl kneeling under him, who is trying to swallow his little brother, and there is even a sexy mature woman who is pressing the girl's head hard, the picture is too exciting, I can't help but feel a little excited, and then the dream dissipates, but the warm and numb feeling is really unforgettable, and there is this magical feeling when I wake up......

"Uh, how can it be so real?" Li Yunfei, who was gradually regaining consciousness, suddenly noticed a tingling sensation coming from under him, and couldn't help but be stunned for a moment. It wasn't until this time that I found that Bai Li'er, who was lying beside her, was actually holding her little brother and doing the same thing as the girl in her dream...... The sudden change is so exciting, no one lives at all, and in the blink of an eye, it is so completely explained.

“…… It's over, there's no going back. "I don't know why, thinking of things that may not be able to go back in the future, I don't have too much disappointment in my heart, and even a little excited, in fact, it's much better in this world than going back to be an otaku, and I can't find such a charming and cute little fairy in the real world.

Bai Lier got out of the quilt with some trepidation, and saw Li Yunfei with a flushed face, but she was even more apprehensive, she instinctively absorbed her husband's Yuanyang just now, which is equivalent to ruining her husband's cultivation, it is really ......

"Yes, I'm sorry!" Bai Lier apologized cautiously.

“…… Well, let's do it again! "Now that they have broken their vows, they can't go to Xitian anyway, and Li Yunfei doesn't have any scruples.

"What?" Bai Lier thought she had heard it wrong.

“…… Dear Li'er, can you do it again like just now, I didn't experience it in my sleep before......" Li Yunfei said with some embarrassment. This first time I went was too fast, it seemed like it was only a few seconds, and I didn't experience it yet, so I was a little unwilling.

"Husband doesn't blame the slave family?"

"Well, if you do it once, I won't blame you." Li Yunfei followed her words and said with a half-finished smile.

“…… Oh, thank you! Bai Lier thought about it and finally agreed, and got into the quilt again, but her heart was moved. She also thought that this was Xianggong wanting to give Yuan Yang more to herself to improve her mana cultivation. She was simple-minded and didn't know at all, Li Yunfei just wanted to have a good time, and she didn't seem to care if she didn't cultivate or not.

……

Without scruples about Li Yunfei, he completely recovered his lustful nature, but after many days of no shame, the two of them were in and out of pairs all day long, whenever night fell, they always went to bed early, and experienced the actions in their imagination on this Bai Lier several times, and the relationship between the two was almost wide and sent an invitation to officially visit the church and get married.

After nearly a month of hard work, the water of the Heishui River has completely restored its clarity, which is a little clearer than before the pollution, and it has also regained its vitality, and from time to time you can see schools of fish swimming in it.

And the lamp oil of the Heishui River was strongly recommended by Li Yunfei, and the little gods and fairies from all walks of life also bought some for the face to try it out, and found that it was much easier to use than ordinary lamp oil.

The river god sells lamp oil, it sounds very weird, in fact, the fairy gods of this world really need to earn some external blocks by means in order to better mix their lives, especially in the small gods who are mixed with people, but there are not many heavenly court Yulu to take, what mountain gods, land and river gods, etc., are all conscientious and conscientious to protect the peace of the place, in order to get a little tribute incense......
