　　Feeling extremely tired and sleepy every day, holding a gear in one hand and a chisel in the other, I fell asleep unknowingly!

　　When he wakes up again!

　　Already lying on the boobies blanket!

　　It's so comfortable... I really want to sleep like this until the end of the day!

　　No, what about Chu Yan?

　　She looks up!

　　I saw a three-meter miniature water tower standing on the edge of the pool!

　　There is a thick bamboo tube standing beside it!

　　The top of the bamboo tube uses a bicycle wheel to make a five-meter-high windmill!

　　The breeze blew the windmill and drove the gears, and water spewed out from a bamboo tube!

　　This device alone turned this pool of stagnant water into active water!

　　But more than that!

　　Chu Yan was also beside the pool, patiently placing the glass stones in the red clay trough!

...... 0

　　"You...what are you doing?"

　　"The last link in filtering!"

　　As Chu Yan said, lay several layers of rags on top of the glass stone, and let the water in the bamboo tube wash onto the rags!

　　"The dirt in the water is physically filtered on the top, the filter cloth is cleaned after a period of time, the bacteria are cultivated below, and then the biochemical filtration is carried out!

　　In this way, the entire pool has the basic conditions for biological filtration! "

　　"Then... shall we scoop up water in it later?"

　　"no!"

　　Chu Yan pointed to the thick bamboo tube: "The water after biochemical filtration will be pumped into the filter tube, which contains island cotton, bamboo charcoal, quartz sand and other mineral filter materials for secondary filtration, and the filtered water will be stored in the water tank! We can drink it directly when we need it!"

　　With that said, Chu Yan flipped a switch on the bamboo pipe in front of the water tank, and clear water flowed out.

　　He took half a glass from a mineral water bottle, took a sip, and poured it into the pool! !

　　"Not bad! However, the flora has not been fully developed, and this is not the cleanest. After a few days, the water in it will be no less than mineral water!"

　　Tian Tian exclaimed: "That gear..."

　　"When you go to bed, I'm all done!"

　　Tian Tian sighed: "Speaking of which, I'm still useless!"

　　"How come?" Chu Yan smiled: "Next, cultivate nitrifying bacteria, you are the most important role!"

　　Tian Tian gave a suspicious "um", and there was an ominous premonition in his heart!thousand.

Chapter 172

　　If Chu Yan said: I need your help.

　　It doesn't feel like this every day!

　　But when he said gently: You are the most important character!

　　I'm out of my mind today!

　　Speaking of which, people who are already exhausted and sweaty after a sleep can still afford the "most important role!"

　　But Chu Yan has already said so, and she still has to ask: "That...what the hell are you using me for!"

　　Chu Yan did not answer directly, but said: "In order to ensure the survival of nitrifying bacteria in large water bodies, it is necessary to stock some fish. The metabolism of fish can provide growth conditions for nitrifying bacteria, but you know, this small island cannot be found. To freshwater fish!"

　　Tian Tian nodded: "Yes, even fresh water is hard to find, let alone fresh water fish!"

　　Chu Yan continued: "So in order for the nitrifying bacteria to survive and work, a substitute must be used!"

　　"Substitutes?" Tian Tian was a little confused for a while.

　　"Correct!"

　　Chu Yan patted Tian Tian on the shoulder: "Tian Tian, didn't you find out? You are the most suitable substitute!"

　　"when……"

　　Every day I feel a head-on blow, my brain is blank!

　　"In other words, let me be... a fish??"

　　"It's not like a fish all the time, or it's an occasional swim! The natural metabolism of the human body will produce some peelings and body fluids, just enough to cultivate nitrifying bacteria! Too much or too little will make the flora collapse!"

　　Tian Tian twitched the corners of his eyes, and then shouted: "Chu Yan, it's really hard for you, how did you come up with such a hentai idea?"

　　"Is this idea very hentai? Well, it's a little bit, but there's nothing you can do about it!

　　If there were twenty freshwater fish, I wouldn't let you do this! "

　　in fact……

　　Chu Yan still has another way!

　　But the task of the system is there, and you have to rely on it to improve your ability. You have no reason to refuse!

　　Shaking his head every day: "Why don't you go by yourself?"

　　Chu Yan said, "I don't sweat as much as you!"

　　"Oh!" Tian Tian looked like he understood: "No wonder you made me do so much hard work, so you wanted me to do this!"

　　"It's not all for this reason. Boys' bodies are slightly acidic, and girls' bodies are weakly alkaline, which is very helpful for water purification!"

　　"Hey?" Tian Tian's eyes suddenly lit up!

　　You don't always say that you don't know I'm a boy or a girl, so why don't I just take care of it?

　　So Tian Tian cleared his throat and said seriously: "Actually... I look like a girl, but I'm actually a boy. For this kind of thing, you should look for a pure girl!"

　　Said and pointed to three busy little girls not far away.

　　But Chu Yan said:

　　"I checked it when you were sleeping just now. Well, you are indeed a girl!"

　　"Eh?"

　　Tian Tian's face suddenly turned red, then he shielded his body and collapsed and shouted, "Chu Yan, you big hentai, to actually do such a thing, I will never be with you again!"

　　Chu Yan smiled and pinched her cheek: "Look, if it's really a boy, it won't react so strongly!"

　　"You... deceive me?"

　　Chu Yan nodded: "Yes! So, be brave and do what a girl should do!"

　　I struggled every day, but I still couldn't accept this task!

　　Then find a reason to hide, anyway, you lied to me just now, I will lie to you again!

　　"Or not!"

　　"why?"

　　"What, I... my aunt is here!"

　　"Don't be funny, I know your date, it's been a few days already!"

　　"I'm confused, can I do it!"

　　Chu Yan opened Tiantian's clothes and leaned down to smell it: "It's obviously not smelly!"

　　Everyday is messy!
