After flipping through it, Zhang Chengyuan realized that he had been confused. The method just now was only for filtering fresh water, not for filtering seawater into fresh water.
The simplest way to turn seawater into fresh water is by distillation, by heating seawater to evaporate it, and then condensing the steam into fresh water. This method can not only obtain fresh water but also salt.
Of course, if you are not in a hurry, you can use the solar evaporation method: place seawater in a shallow container, use the heat of sunlight to evaporate water molecules, and then condense the evaporated water vapor into fresh water.
Specific operation method: Find a shallow container, such as a tray, and then place a black material, such as a stone, on top of the container to absorb more heat and prevent seawater from evaporating directly.
These are the two easiest methods she feels, and there are many other methods.
She made all three simple devices and put them in the illustrated book. Whether they are used or not is one thing, and whether they are available or not is another thing. No one can tell what will happen in the future.
Zhang Chengyuan lived here like this, year after year, sometimes she would feel deserted. At this time, she would call Tianqing and find it to chat with her.
It was the same this time. Zhang Chengyuan lay on the rocking chair she placed on the beach. He prepared one for Tian Qing and set up a table with fruits and juice on it. He closed his eyes and enjoyed the sunbath.
He kept talking: "Tianqing, how long do you think I can live? I am 119 years old this year."
Tian Qing sat on the rocking chair, holding a coconut and drinking. She squinted her eyes in enjoyment, took a big gulp and swallowed, and then said: "Eleven years."
Zhang Chengyuan opened his eyes suddenly and asked, "Do I have eleven more years?"
Tian Qing nodded in response.
Zhang Chengyuan lay back again, opened the panel and looked at:

"Secret of Immortality" At 1%, the life span was 120 years. Now, at 2%, it is 130 years. Is it 10 years more than 1%? She couldn't confirm yet.
In addition, there is "Julijue". At 6%, several kilograms of things are easy for her. Before, she thought that a powerful pill would increase her weight by 1%, but later she found out that it was not the case.
She has eaten at least ten pills in this world, but it has only increased by four percent. Since reaching ten percent, she found that her strength has increased several times. Now if there is a wild boar that is as small as the hill , she can send it to death with one punch.
She is no longer sure how much strength she has, but she has enough strength and confidence.
Looking at the skills she possessed, she thought that maybe only "Juli Jue" was slightly inferior.
After Zhang Chengyuan closed the panel, he continued to enjoy life.
But Tian Qing spoke: "How long will it take for you to come back after you leave?"
How could Zhang Chengyuan know? She opened her eyes and smiled and joked: "What? You can't bear to leave me?"
Tianqing ignored these unnutritious words and became familiar with Zhang Chengyuan over the years. It knew more about humans: "It needs you directly."
Zhang Chengyuan lay down for a while and tilted his head to look at it: "If you don't want to let me go, I'll just say it. You are enough in this world."
Tian Qing looked at her without speaking.
Zhang Chengyuan quickly surrendered: "Okay, okay, I will definitely come back, but I don't know when I will come back. I have never been to other attached worlds, so I know this."
After getting along with her for so many years, Zhang Chengyuan already treats Tianqing as his own child.
Tianqing also regards Zhang Chengyuan as the closest person.
In the next eleven years, Tian Qing followed Zhang Chengyuan almost all the time. When she went to hunt marine creatures, Tian Qing followed her and even helped.
Before, it disliked or even rejected her, thinking that what she did was too immoral.
The more reluctant you are to let go, the faster time passes. In the blink of an eye, Zhang Chengyuan is 130 years old.
Zhang Chengyuan herself also felt powerless. She knew her end had come, because in her last life she suddenly felt powerless one day, so she was still experienced.
"Tianqing, come here and give me a hug."
Tian Qing's wrinkled face is simply not too cute. Over the past eleven years, Zhang Chengyuan has tried his best to squeeze his little face. Otherwise, Tian Qing would not let him kiss her, and Zhang Chengyuan would drool all over his face.
It's so small, so chubby and soft that you can't put it down. Zhang Chengyuan sometimes feels like she's perverted, but she really loves it and she can't control herself.
She was so perverted to her daughter after giving birth in the previous world, but this was only before she was three years old, after which she seemed to return to normal.
Although she still thinks her daughter is cute, she is no longer so rare. She thought it was rare enough, but now she realizes that it is not at all.
Tian Qing turned around and was about to run away, Zhang Chengyuan reached out to grab him, and obviously caught him, but Tian Qing just used his usual playful strength, but he broke free in an instant.
Tian Qing was stunned, and Zhang Chengyuan was also stunned. She didn't expect that her strength had become so much stronger, and that she would still be unable to exert any strength if she was not strong enough.
But Tianqing realized the reason for Zhang Chengyuan's weakness and she was leaving.
Zhang Chengyuan raised a bright smile and reached out to Tianqing for a hug: "Give me a hug."
Tian Qing sat silently in Zhang Chengyuan's arms, her eyelids lowered and her face expressionless, not knowing what she was thinking.
After a while, Tian Qing suddenly said: "Are you leaving?"
She nodded and said, "The lifespan of my body has come to an end."
Tian Qing looked up at her and was about to blurt out something. After seeing Zhang Chengyuan's smiling eyes, he swallowed his words and lowered his head again.
As usual, Zhang Chengyuan squeezed its cute face and even kissed it quietly, but it didn't respond.
Zhang Chengyuan sighed and touched its head, and stopped fussing with it: "Tianqing, don't be sad, I just left and it doesn't mean I won't come back."
Tian Qing raised her head with confusion and confusion in her eyes: "Am I sad?"
After receiving Zhang Chengyuan's affirmation, Tianqing murmured: "So this is the feeling of sadness."
After a while, Tian Qing made another request: "You should come back to see me more often, I will miss you."
Zhang Chengyuan nodded happily: "Okay, I will miss you too. You should take a good look at the world after I leave. I will leave all my things to you. You can use them yourself or give them to someone you are destined to... "
