"I obviously ate a lot in the afternoon......" Feng Xue reluctantly got out of her state of visualization, walked out of the bedroom and began to look for instant noodles, but as soon as she pushed the door open, she saw Yun Rou sitting on the sofa with a smile on her face and looking at him-

"Senior brother's first time cultivating, he must be hungry, Yunrou can't do anything else, so she can only soak two bowls of noodles, I hope senior brother won't dislike it."

"How so!" In just a few minutes, Feng Xue was a little flustered with hunger, picked up a bowl of instant noodles and ate it.

I don't know how Yunrou grasped the time, but it was just soaked, whether it was the temperature or the softness and hardness of the noodles, it was just right, and it was definitely not just a random time to soak it.

After eating one bowl, Yun Rou handed over the second bowl, which was almost exactly the same temperature as the previous bowl when it was entered, so you can know that these noodles are definitely not soaked at the same time!

"This kettle is really easy to use, you can drink hot water at any time with it......" Yun Rou said, and lifted the kettle to soak in a bowl of noodles.

"Uh...... You even have seven-incense cars and elevators on Penglai Island, and there is no hot water kettle? Feng Xue looked at Yunlan with a strange expression, and always felt that this technology tree was a little crooked!

"Yes, because you can't consume spiritual power at will, most of the institutions on Penglai Island are powered by water and wind power, although there are water boiling tools powered by yang power (solar energy), but they can only be used on sunny days, and they still have to use firewood on weekdays, as for using spiritual power to keep warm or something, it's really too luxurious." Yun Rou also sighed when she mentioned Penglai Island, but Feng Xue was more impacted, saying that you have all studied the application of solar energy, can't you study the thermos?

But at the moment he spoke, he suddenly got stuck, because he suddenly realized that it was not imagination or technology that limited the technology of Penglai Island, but the material.

After all, it's just a small island, and the sea can't go down (the scope of the Penglai Island Spirit Gathering Array does not include the ocean, because the fluidity of the sea water is easy to cause spiritual power to escape), how many resources can there be? Feng Xue thinks that they haven't developed solar cells yet, probably because there are not enough materials, right?

Speaking of which, the collapse of the Xiuzhen civilization is actually very reasonable, just like human beings, if one day, "electricity" disappears, then even if your human civilization does not collapse, you can only jump back to the steam era.

Imagine if one day, all the power generation equipment fails, and the oxygen content in the atmosphere begins to gradually decrease, can human beings, like cultivators, create an ecosystem that can allow some people to hide in it and survive for at least 600 years in just a few decades?

The answer is obviously no, but the cultivators have done it, using the strength of 100,000 people to do what six billion people can't do, and their level of civilization can be imagined.

Thinking of this, Feng Xue felt that it was better not to figure out the civilization of the cultivators with her mortal eyes, so she picked up the bowl and continued to eat noodles.

"Senior brother, although this instant noodle is convenient and delicious, there are too few pastries in it, if you want to support your cultivation during the refining period, you have to eat at least thirty bowls a day, but this box is only about twenty bags......" Watching Feng Xue pull the noodle chop into her mouth bowl by bowl, Yun Rou smiled happily, but Feng Xue found that there was still a trace of distress on her face.

"Uh...... Is it so exaggerated? Feng Xueleng took a moment and found that her three bowls of noodles were in her stomach, but she was just not hungry, and if she wanted to be full, she was indeed far away!

"Not an exaggeration." Yun Rou shook her head and said, "Generally, the amount of food eaten by a cultivator in the refining period will increase by about five times, if an ordinary person can eat five bowls of instant noodles a day, a cultivator in the refining period will have to eat at least twenty-five bowls to be able to supply the consumption of chemical qi." If there is not enough food to refine the essence and qi, it will cause a loss of essence and blood, and the more you practice, the worse your body will become. If it is a physical cultivation, it will be increased by five times, and the monks of Tianyang Mountain will eat seven buckets of rice per person every day during the refining period (about one hundred catties of steamed rice, while ordinary men will only consider their caloric needs, and they will eat about four catties of steamed rice every day, that is, one catty of dry rice)! ”

"......" Feng Xue grinned, it turns out that the solar eclipse of seven buckets of rice is not a myth and legend?

At this moment, Feng Xue suddenly had a desire to eat a buffet every day, but if she thought about it carefully, she was also a big man worth dozens of tons of gold, and it was not good to bully the buffet boss again?

So he shook his head, rolled his eyes, and took out a handful of chocolates from the snacks he bought today and handed them to Yun Rou-

"How are you looking at things?"

Feng Xue bought a lot of snacks today, but Yun Rou and Yun Lan both belonged to what kind of people who could restrain their desires, so they didn't take each one apart and try it, but now that she had a legitimate reason, Yun Rou opened it with her eyes shining, stuffed a piece into her mouth, and then closed her eyes and meditated......

After about three minutes, Yun Rou opened her eyes, nodded a little happily and said, "This candy called chocolate contains more than five times the essence of rice, but it is not difficult to eat, it should be considered a very good food, senior brother only needs to eat four catties of this candy every day, it should be enough." ”

"Four pounds?" Feng Xue's face darkened at that time, and she looked down at the chocolate package, which said net content: 14g.

In other words, Feng Xue has to eat more than 140 bars of chocolate every day!

"Well, is there any other way?" Feng Xue calculated, she has to eat five boxes of chocolates a day, let alone really eat them, it's scary to think about it, okay?

However, Feng Xue also knew that it was impossible, otherwise the monks of Penglai Island would not have eaten brown rice and had a fear of food, but-

"Yes, [one stone (dan) yellow sorghum], also known as the essence pill, that is, the Bigu Pill misrepresented by mortals, is a pill made from one stone (about one hundred and fifty catties) of yellow sorghum rice (corn), one pill is enough for five days of physical cultivation, if it is an ordinary monk, one grain can be used for a month, after many changes, any food can be refined."

"There is such a thing, why do the monks of Penglai Island still have food phobia?" Feng Xue asked a little strangely.

"Because practicing this elixir requires Danhuo and a lot of aura!" Yun Rou replied as a matter of course, "Although Penglai Island could already use yang power to produce Dan Fire three hundred years ago, the gap in aura cannot be filled in any way!" ”

Hearing this, Feng Xue understood, as long as Penglai Island had any flaws, as long as the spiritual power was insufficient, it would definitely be able to explain it, but think about it, hundreds of thousands of refining qi cultivators in Penglai, even if a pill only needs 0.01 unit of spiritual power, after expanding to hundreds of thousands, it will be a huge consumption, okay? And that's just for a month!

"So it's another one you can't refine?" Feng Xue called a (╯"dish′)╯(┻━┻!) The hope that had just been raised is gone, and it's like saying, "Is there money?" Yes. Where is it? frozen. ”

"Although I haven't practiced, Yunrou has a Dan formula!"
