A moment later, the changes stopped.
The system's tone sounded.
[Ding! Congratulations, host, the evolution is complete!]
[This evolution has consumed one evolution chance. The result of the evolution is: Contaminated water =>Drinkable water!]
Zhou Yuan was overjoyed when he heard the message. He could not help but mutter.
"The heavens didn't choose to kill me!"
Then, he immediately buried his head in the reservoir and started drinking the water crazily.
Zhou Yuan had not drunk a single drop of water for three days. He was like a sponge that had been exposed to the sun and was in dire need of water.
After a round of drinking, Zhou Yuan lay down and let out a long breath.
His slightly swollen stomach did not make him feel uncomfortable at all. At the moment, he could only feel the comfort of having his thirst quenched.
Every cell in his body was cheering.
"F*ck! Those who waste water should die!"
Zhou Yuan cursed in a low voice.
He was scolding himself for not knowing how to save water in the past, and at the same time, he was also scolding the humans who did not cherish water resources back in the day.
The reason why life could be born was because of the existence of water!
70% of the human body was made up of water, so the importance of water was self-evident.
Zhou Yuan rested for a while before turning over and sitting up. He looked at the reservoir beside him, which still had a lot of water left, and immediately found something to cover the reservoir.
Then, he collected some water bottles around him.
As the most common product in the glorious era, plastic bottles could be seen everywhere in the ruins.
However, no one was collecting the junk for a single cent now.
After filling the remaining water into the bottles, Zhou Yuan looked at the bottles in front of him and felt a sense of security.
In the following days, he would not have to worry about drinkable water.
As long as he consumed them wisely, these bottles of water would be enough for him to drink for ten days to half a month.
After resolving the crisis of life and death, Zhou Yuan could not help but think about how he was going to live the rest of his life.
First of all, as someone who had experienced a life of luxury in peaceful times, Zhou Yuan would definitely not be satisfied with just drinkable water.
This requirement was too low!
With such a powerful 'Unlimited Evolution System', as long as he operated it properly, he could even build a new city or even a Kingdom, let alone live a rich life.
After all, with the system's support, he didn't have to consider the restrictions of Science and Technology on production and development.
In the previous world, in order to increase the production of food, it required selfless scientists to research day after day, year after year.
Only with a technological breakthrough could they achieve an increase in production.
And now, as long as he had enough gold coins, he could instantly evolve anything.
The ability to completely break the norm would allow him to quickly establish his own kingdom.
Although Zhou Yuan did not want to be the king, there were some things he had to do in order to have a better life.
The premise and core of all this was the system.
To be more precise, it was the gold coins of the system.
With the gold coins, he would have more evolution chances, and with the evolution chances, he would have infinite possibilities!
For him, the most important thing now was to search for rare items and exchange them for gold coins.
What could be considered a rare item in the apocalypse?
There were many!
Food, drinks, clothes, and other necessities.
From a small bag of instant noodles to a large vehicle that could be started.
All of them were considered rare items!
According to the system's definition, as long as it could help people survive in the wasteland, it would be considered a valuable item. The lesser the item was, the more scarce it was.
Although Zhou Yuan could search for these rare items himself, it would be too inefficient.
The best way was to become an 'exchange merchant', just like those people who controlled water resources before.
He wanted others to bring rare items to him in exchange for resources.
And now, he had some water that he couldn't finish in a short time.
Exchanging water for other people's scarce resources, then exchanging it for system gold coins to obtain evolution chances.
Ultimately, he could use the system to evolve items again and obtain more resources!
This plan was perfect!
After some consideration, Zhou Yuan set a rigid rule for himself.
He had to control the exchange ratio.
If he could exchange an item with a mouthful of water, he would definitely not use a glass of water.
This was not cruelty, this was the law of survival.
If he was too generous, then he would be the one to suffer in the end, and he would be the one to die.
Zhou Yuan, who had lived two lives, experienced such a drastic change, and had just survived a life and death crisis, was now as cold-hearted as an employee who had killed fish for ten years without any mercy.
With that in mind, Zhou Yuan packed the water bottles in his bag and was ready to leave.
At this moment, six exhausted figures were walking toward him.
Zhou Yuan focused his eyes and a few names popped up in his mind.
These six people were all his classmates after he had transmigrated.
After the war broke out, there were still many survivors in their city as it was not the main target of the attacks.
More than half of the teachers in Zhou Yuan's school managed to survive.
Therefore, Zhou Yuan was not surprised to see his classmates in the vicinity.
To his surprise, the prettiest girl in the class, Tian Jinghan, was also there.
At this stage, it was no longer easy to find food and clean water with a simple search.
Even Zhou Yuan, a man, almost died of thirst.
Yet a beautiful and delicate-looking classmate was still alive?
After some thought, Zhou Yuan finally understood.
No matter what, women always had one more way to survive than men.
This was inborn, and there was no other way.
Shaking his head, Zhou Yuan prepared to leave.
In this era where humans were against one another, he had no right to judge anyone. It was all for the sake of survival.
At this moment, Zhou Yuan frowned.
He noticed that the six people were walking straight toward him, and they were walking faster and faster. In the end, they were actually sprinting.
Looking at the water bottles that he had yet to put away, Zhou Yuan immediately understood.
The other party saw that he had water in his hand and wanted to ask for some water.
Zhou Yuan did not panic. He did not immediately put away the water bottle, but instead picked it up.
He had always wanted to be an 'exchange merchant', and now he could use these students to test his skills.
However, one must always be on guard against others!
Zhou Yuan casually picked up the rusty nail and held it tightly in his hand.
If anyone had any ill intentions, they would have to suffer being pierced by a nail.
Being pierced by a nail at this time was not as simple as tetanus.
All kinds of germs and viruses, coupled with radiation, would kill anyone who was punctured.
The six of them approached Zhou Yuan and looked at the clear water in the bottle with shining eyes.
Even without Zhou Yuan's explanation, they knew that this was clean water that could be drunk.
After all, at this point in time, almost all the water was black and contained a lot of impurities.
Almost all the water that was slightly clear was drinkable.
Not to mention the crystal clear water in Zhou Yuan's hand, which was almost comparable to the mineral water in the past.
They looked at the water bottle and could even recall the sweet taste.
In an instant, they swarmed over like bees, wanting to ask for the water.
