"However, my hypnotic powder needs to be of a certain concentration to be effective, and if I don't know how much air the sewer can hold, if the dose is not enough, the plan will fail." Fluttershy adds.

"That's it......" Yun Hai patted his head, he really forgot about this, so he began to calculate the total volume of the sewer against the various data given on the drawings, but he didn't understand European mathematics and engineering, but he found that he couldn't understand the above things at all. "What centimeters and decimeters, in Shenzhou has always been the size of zhang, and how to calculate these three views?"

"I'm stupid, I'll do it. Akali snatched the drawing, glanced at the sea of clouds with disdain, picked up a quill and calculated.

"It's still a princess who is educated, and she directly compares me to a sheep farmer. Yun Hai watched Akali walk the dragon and snake, quickly scratching all kinds of unknown things on the scratch paper, and sighed in his heart, he suddenly had a feeling that when he was learning mathematics in Tianji Peak, Shen Mengxue could successfully solve the answer every time, while he and Jiang Hao, the two stupid people, could only stare dryly.

"We members of the European aristocracy, especially the royal family, have to receive all kinds of training since childhood, not only military skills, magic, holy light, horsemanship, but also mathematics, literature, law, history, engineering, a series of things, from dark to dark in one day, it is simply annoying......" Caterina suddenly rubbed her head and complained.

"Uh...... It's terrifying......" Yun Hai couldn't imagine what kind of concept it was at all, and he suddenly felt that these noble sons and young ladies in fine clothes and jade food were simply the most pitiful people in the world, from the black sky to the black sky, and they could only sleep for a few hours a day...... Definitely going to die!

"Why is it that all of a sudden, hehe~" Fluttershy whispered to the sea of clouds.

"You would really base your happiness on the pain of others. Yunhai also laughed.

"Come on, I feel the urge to hit the wall when I think about how many pounds of phosphorus powder I have to make in a while, and I'm happy! I'm going to vomit blood, okay, it's really blood!" Fluttershy can't help but go crazy.

"Don't hit the wall, don't vomit blood, I'll be distressed, can we make a good job?" Yun Hai muttered quietly.

"Huh......" Fluttershy pouts and pouts, puffing her chest against the sea of clouds.

"Alright, I've done the math three times, and it should be fine, Alma, can you see if my calculations are wrong?" Akali let out a sigh of relief, stretched, and handed Alma the scratch paper in her hand.

"This ......" Alma suddenly tilted her little head and looked at Akali helplessly. "You're writing this too messy, where did you start?"

"You don't have to worry about that, just see if the calculations are correct at every step. ”

"Oh......" Alma just glanced at the scratch paper, and after a few seconds, said, "No problem, the result should be correct, if you didn't use the wrong formula or anything." ”

"No!" Fluttershy is shocked. "How did Alma manage to finish that big calculation in an instant?"

"It's normal, people are humanoid weapons, and their computing power is far stronger than ordinary people, and you can find out when you are fighting. Yunhai didn't think it was strange.

"The results are in, and these are the things. Akali says, handing the scratch paper to Fluttershy.

"Ten hundred thousand...... Uh, stupid man, how big is that?" Fluttershy takes the scratch paper, instantly startled by the numbers in front of her. "It's six figures, are these sewer repairers crazy?"

"I don't know what to say, but I just think that you have to vomit blood this time. Yunhai scratched his head.

"Okay, and then there's the lowest effective concentration. Akali stood up. "Fluttershy, use hypnotic powder on me, I'll see how much of it works, and I'll hold my breath. ”

"Alright, everybody back away. As she spoke, the crowd dispersed, Fluttershy flipped her wings slightly, and the breeze swept through, and nothing seemed to change around Akali, but everyone could feel that there was something in the air around Akali.

"Is it okay? I can clear it. Fluttershy asks.

Akali didn't dare to speak, so she nodded.

"I can already feel the specific concentration, and then I can calculate the specific amount of phosphorus powder, wait a minute. ”

As she spoke, Akali started to put pen to paper again, and this time in less than half a minute, the results came out.

"More than ten pounds, oh my God!"

After seeing the results, Fluttershy suddenly had the urge to faint, she was now crying without tears, more than ten pounds of phosphorus powder, this is definitely a historic project, the phosphorus powder she has used so far in her life so far, it adds up to less than a pound, right?

His weight is only in his eighties, and this kind of measurement really tires me.

"This is already the most conservative estimate, including the Lang fee and the part absorbed by the water in the sewers, it will take 20 percent more than the original to ensure the effect......," Akali also felt that this was definitely a very harsh task, and explained in a statement.

"Okay, okay, needless to say......" Fluttershy waved her hand weakly and turned to Yunhai and said, "You asked me to take this thankless job, you have to help me!"

"Say, let me help you, I will help you as much as you ask me!" Yun Hai's heart also began to feel distressed, he never thought that he would hypnotize all the enemy troops in the sewer, and he actually needed so much phosphorus powder, and he began to regret it.

"You do this and ...... like this" Fluttershy whispers softly next to Yunhai, her face slightly red, and Yunhai's face is a little red after hearing this, which makes people a little confused.

"What are you two muttering?" Akali wondered, saying something that would make both of them blush?

"You don't have to worry about this, I'll send you enough phosphor powder in a glass bottle early tomorrow morning. Yunhai said. "Without further ado, let's do it now, you can also selectively block some passages, remember to strengthen your vigilance. ”

"Do you need someone to help you?" called Akali from afar.

"No!"

On the streets of Paris.

"You really don't let me go at any time, I didn't expect to be assigned such a job again......" Under the moonlight, the two of them walked along the street like this, looking at the cavalry that galloped by them from time to time.

"Come on, if it weren't for the fact that my Buddha and Demon Qi are too insufficient, how could I give you this opportunity to take advantage of me!" Fluttershy said with a red face and gritted teeth. "Hmph, don't pretend, I can see that you're already looking forward to it......"

"You know so much......

Since Fluttershy's phosphor powder is made by her own physical strength, and then empowered by the Buddha's and Demon's two qi, Fluttershy's own energy is far from being able to complete the task in terms of both physical strength and the reserves of the Buddha's and demon's two qi, so she must let the breath of the sea of clouds help her, that is, replenish her Buddha's and demon's two qi and physical strength.

However, the breath of different people has an instinctive resistance to each other, so it is generally not feasible to directly replenish energy to other people, and it is even more fantastical to replenish physical strength, but the cultivation of the Emperor and Tianzheng in the sea of clouds, as well as the abundant reserves of Buddha and Demon Qi, make this impossible possible.

The plan is that Yunhai first lays out a metamorphosis array, constantly extracting the aura of heaven and earth around her, otherwise the combined strength of the two people may not be able to produce enough phosphorus powder, the two of them sit in the eyes of the yin and yang fish, Fluttershy is single-mindedly responsible for making phosphorus powder with hypnotic effect, and Yunhai needs to continuously deliver her Buddha and demon qi, and constantly nourish her body with her own yin and yang qi, so that she will not be physically exhausted.

But if you want to do that, you have to press your hands tightly on the front and back of Fluttershy's dantian until the job is done.

"So, it's a shame to be pressed on your stomach like this all night!" Fluttershy blushes and grumbles.

"What are you afraid of, you've done more embarrassing things anyway, such as the ...... in Brandenburg," Yun Hai laughed ambiguously. "That touch, it's really ...... Whew-"

"I said it was an accident, you bastard!" Fluttershy suddenly bites into the sea of clouds. "Let you say, let you say, I'll bite you, I'll bite you!"

In Paris, shrouded in the haze of war, under the white moonlight, two frolicking figures disappeared into the night......

"Okay, that's it. ”

In the bedroom of the sea of clouds, the shape of gossip with a shimmering light on the ground has been completed, the sea of clouds and Fluttershy have also been in place, and Fluttershy's side has also made all the preparations, the dragon soul stone, obsidian, sea soul beads, and lapis lazuli have all emitted a faint light, suspended around the formation, and began to supply their own energy continuously, while the infatuation stone is suspended in the center of the array, and the pink breath is very beautiful.

"I must have had a brain pump to agree to your crazy plan...... Fluttershy glances at the large stack of glass bottles in the corner of the room, which are the ones containing phosphorus powder. "I warn you, don't touch your hands, or I'll just stab you to death with the Spear of Dawn!"

"Hmph, that depends on my mood......" Yunhai said as he placed his hands on Fluttershy's stomach and back and began to prepare to breathe in his own breath.

"Still think it's awkward......" Fluttershy snorted with a blushing face.

"Relax, merge our breath and don't resist. ”

The sea of clouds begins to guide Fluttershy little by little, and finally, the two of them no longer resist each other, as if they are lovers after a long absence, and they can no longer distinguish each other.

At the same time, Fluttershy, who is working with her eyes closed, suddenly has a happy smile on her lips, which is so sweet.
