I have a zombie assist system

The next morning, when Wang Qiushui woke up, he found himself lying on the bed.She sat up and stretched, then asked, "I remember we were chatting last night, when did you go to sleep?"

He smiled, "You still have the nerve to say it, and fell asleep while chatting, and then I had to carry you back to bed."

Wang Qiushui blushed, and asked again, "Then do you still have nightmares later?"

He shook his head, "Thanks to you chatting with me for a while, I slept soundly in the back."

Wang Qiushui nodded, "Then I don't worry, I was really tired yesterday, that's why I fell asleep."

He brought out the breakfast, "Well, you should wash up first, and have breakfast after washing up."

Only then did Wang Qiushui get up from the bed and go to wash up.

After breakfast, Wang Qiushui asked, "What are we going to do today? Are we going to kill zombies and get to level 2 early?"

He waved his hand, "Don't worry, it's just two zombies, that's just two hammers. Let's try the water purifier today and get some water."

Wang Qiushui looked at the little water left in the kitchen, "Well, it just so happens that the sun is shining brightly today, but I don't know if the water purifier is powerful or not."

The two of them carried the buckets and walked downstairs. The water purifier was placed on the second floor when they came back yesterday. It was placed together with the water, so there was no need to move it around.

Opening the door of the water storage room, both of them felt their breathing paused. The air in this closed room was too turbid, and it made people feel uncomfortable once the door was opened.

Wang Qiushui covered his nose, feeling better, and said in a dull voice, "Why didn't you open the window earlier, it's so boring."

He also held his nose, "If you open the window, I'm afraid that other things will come in and pollute the water. For example, if a bug or cockroach falls in, even if you use a water purifier to purify it, you can still drink it." go down?"

Wang Qiushui waved his hand, "Don't talk about it, it's disgusting to think about it. But now, it looks very clean, not even a shadow of cockroaches."

He moved the water purifier and bucket in, "Yeah, it's too clean."

Looking at the clean ground, he couldn't help but think of his previous speculation. It seemed that even the cockroaches were doomed.

Wang Qiushui walked over and opened the window, "Now that we are watching, it should be fine for ventilation and ventilation."

He didn't say anything, but looked at the water purifier.Speaking of which, after the system transformation, he hasn't checked the properties of the water purifier, so he doesn't know if it has any functions.

The system popped up in a timely manner: "Since the water purifier is not a weapon item, it will not appear on the host panel. If the host wants to check the properties, just put his hand on the water purifier."

He put his hand on the water purifier as he said, and a panel of the water purifier appeared in front of him.

Introduction: No matter what kind of water, no matter what viruses and bacteria are in the water, it can be purified to reach the level of direct drinking water. It is definitely a must-have choice for home travel and doomsday survival.

Purified water each time: 2L
Time required for each purification: 5 minutes

Suggested selling price: 20 experience points

He nodded. 2L of water is just as much happy water as a fat house.And the time is not very long, it will be done in 5 minutes.

However, when he saw the final suggested selling price, he was not calm at all.

He gritted his teeth and said, "Come out of the system, tell me, what is the suggested price? I remember you wrote 100 experience points in the mall, and I spent 30 experience points on the old one."

System: "Well, you know, the end is here and the economy is in recession, so of course the middlemen have to earn some price difference."

He didn't even know what the system meant by these illogical words, so he said directly, "Come on, system, stick your head over here, and I'll give you a buff."

Soon, he shook his head again, "No, I'm so mad at you, return my hard-earned money."

The system said carefully, "Well, how can the duck that eats the mouth let it fly away? No, how can the money that is eaten in the mouth still spit out?"

He said angrily, "What did you say?"

The system quickly said, "No, what I mean is, I can upgrade your water purifier to make it more convenient to use. Don't worry, it's free this time, no money will be charged."

He snorted coldly, "Isn't the water purifier just for purifying water? What's the difference if you upgrade it?"

He knew that he would not be able to get back the experience points that were cheated by the system, so he had to find a way to get more benefits.

The system chuckled, "You'll find out if you look again."

He put his hand on the water purifier, and a panel of the water purifier appeared in front of him again.

Super Invincible Water Purifier 2.0
Introduction: slightly, it can reach the level of mountain spring water.

Purified water each time: 4L
Time required for each purification: 1 minutes
Energy: solar energy (energy storage possible)

Suggested selling price: 30 experience points

He nodded, from direct drinking water to mountain spring water, the capacity of purified water was doubled, the time was reduced to 1 minute, and the efficiency was greatly improved.Moreover, the recommended selling price has reached 30 experience points, which is not a loss.

Still, he asked, "What does this storable energy mean?"

System: "The previous water purifier required you to place it in the sun and absorb solar energy to use it, so it can't be used at night. But now it can be placed in the sun to recharge, and it can be used during the day and night, and on cloudy and rainy days. The most The important thing is, how long you charge it, you can use it as long as possible.”

He nodded appreciatively, "Then the price-performance ratio is still very high, and it can be used for a long time after charging once."

System: "It's okay, I'll go first."

He quickly shouted, "Wait, besides upgrading the water purifier, can you upgrade anything else?"

System: "Everything can be upgraded, but the price of this upgrade,"

He interrupted directly, "I suggest you think it through before you speak."

System: "I will definitely give you the best price."

He waved his hand, "It's okay, you step back."

At this time, Wang Qiushui came back, "How is it? Can this water purifier work?"

He moved the water purifier to the window sill, "It can be used, but it needs to be exposed to the sun and recharged for a while."

Wang Qiushui also came out, looked at the lush plants outside, and sighed, "All the people and zombies are dead, it feels so quiet, as if there are only two of us left in the world."

Hearing this, his expression changed.

Wang Qiushui quickly asked, "What's wrong?"

He sighed, "The quietness you just said reminded me, it seems that I haven't heard the sound of birds since the end of the day."

Wang Qiushui suddenly realized, "It really is."
