Start in a Desert Island and Picked Up Hinata

With a wok!

Although it looks a little different on the outside, it is really much better than iron milk powder cans!

Cook what you want to cook!

Next, consider building more ironware!

Hammer, pliers, axe, machete, hoe, shovel, saw, the more the better!

With these tools, Chu Yan's work efficiency will have another qualitative leap!

To build these things, you have to find more ore and prepare more charcoal and red clay!

This is a long-term job and needs to be done bit by bit!

Before that, the freshwater problem in the camp had a new situation!

Over a period of time, more than half of the water in the two pools has been used, which is nothing.

Fresh water was originally reserved for use.

But then the problem is that the water quality is getting worse and worse!

After all, it is Chen Shui, and there is still dust falling in it every day, green moss grows on the walls, and microorganisms will slowly breed!

Although this kind of water can still be drunk after it is boiled, it will smell of rotten leaves, which will affect the taste.

And this is only more than a month, if you wait another month, these two pools of water will properly become stagnant water!

In contrast, Chu Yan found a problem!

510 was originally reserved for drinking water, the water quality is getting more and more muddy, but the fresh water pool for bathing and watering the girls, although moss grows, but the water quality is very clear!

Twist and compare with your hands, and the water in the bath is cleaner!

The girls also discovered this problem. Little Sakura also proudly said: "Our girls have clean bodies, and the used water is getting clearer and clearer!"

Chu Yan meditated, consulted the manual in his mind, and understood the principle!

"The water is clear because of the high bacterial content!"

The four girls were shocked!

Ino worried: "Huh? Does that mean that we have been bathing in the germ pool?"

Chu Yan smiled: "Don't worry about this, because the bacteria I'm talking about are not harmful bacteria, but nitrifying bacteria!"

"Nitrifying bacteria?"

"A kind of aerobic bacteria that exists widely in nature, has a powerful effect of purifying water quality! More importantly, it does not harm the body at all!!"

"Bacterial water purification?"

Little Sakura thought for a while: "This is the first time I have heard of it!"

"High-end fish farmers know how to cultivate nitrifying bacteria! It can be said that if the bacteria are well cultivated, whoever will do better, and if the water is good, the fish will naturally be healed!"

"Do you know how to raise fish?"

"Understand a little!"

Tenten nodded: "I admire...but why is there in one pool and not in the other?"

Chu Yan squatted beside the two pools:

"In our drinking pool, the water in the pool is standing still for a long time, and the oxygen capacity is small, so it is difficult for nitrifying bacteria to survive!(Read more @ mtlarchive.com)

In the swimming pool, because you often play in the water, the water often flows, and a small amount of skin fragments provide food for the nitrifying bacteria, so the nitrifying bacteria are relatively active! "

Hinata said: "That's why the swimming pool looks cleaner than the drinking pool!"

"Yes!"

Little Sakura said, "So, is it because of us?"

"you can say so!"

"So...we're going to drink pool water from now on?"

Chu Yan smiled: "Although it may be difficult for you to say that, it should be so sensibly!!"

"No..."

Chu Yan thought for a moment: "However, this gives me a hint!"

"What hint!"

"Through physical filtration, bamboo charcoal adsorption, the establishment of nitrifying bacteria groups, to create a complete ecological water purification system!"

Little Sakura said, "Sounds more complicated than filtering tap water!"

Chu Yan snorted: "The water purified in this way is much healthier than tap water!

The most high-end fish farmers will raise air tanks, the water is so clean that no impurities can be seen, and the fish are like swimming in the air! "

Hinata said: "It sounds amazing!"

Tenten curled his lips: "I always feel awkward to use bacteria to purify water!"

Ino said: "Obviously filtering and precipitation can be used!"

Hinata said, "I also think filtering is better!"

"Yes, this is the right way!"

Little Sakura nodded and said, "Otherwise, let's have a competition!"

Ino agrees: "Yes, a group of boys, a group of girls..."

"Wait, here it is again?"

Ino said leisurely: "You will no longer doubt, we are all girls!"

Chu Yan stroked his chin: "In terms of gender... the other three girls can be determined, but I haven't seen Tenten..."

Tenten clenched his small fist: "Don't get into it... wait, other girls..."

Tenten turned his head, all three girls blushed...

"Huh? When did it all happen?"

Chu Yan gave Tenten a hug: "Well, the three of you are too many. Tenten can't determine whether you are male or female. It counts as my teammates. You don't have any comments... Whoops!"

Tenten knocked Chu Yan on the head: "Asshole, is my gender so hard to tell?"

"This is not important, I have to have a teammate anyway!"

Tenten sighed, "Okay! I'm going to be with Chu Yan!"

Little Sakura said: "Let's purify a pool in each team. Whoever purifies more cleanly will win!"

Tenten leaned over: "Hey, Chu Yan, is your method sure?"

Chu Yan chuckled, "Don't worry!"

Ino said, "Wait, this competition can't be done without rewards and punishments!"

Chu Yan thought for a while: "If I win, I will kiss each of you! If you win, I will kiss each of you!"

"no!"

"Then what do you say about rewards and punishments?"

"Which team loses, clean the clothes of the winning team for a week!"

Chu Yan looked at Tenten and said with a solemn expression: "If we lose, then the rest will depend on you!"

"what?"

"Stop it, hurry up and prepare!"

Then, the two groups began to prepare intensively!

Little Sakura chopped a few pieces of bamboo, weaved it into a net, covered it with old cloth, and prepared to filter it later!

Ino and Hinata collect sand!

And Chu Yan took Tenten to the bamboo forest!

"The first thing we do is a water tank, then the filter tank and pump, and finally the nitrifying bacteria!"

Tenten nodded!

"Oh... wait, pump? I heard that right!"

"That's right!"

"But we don't have an electrical system!"

"Is there no electricity, isn't there still wind energy?".
