Li Lechen wasn't particularly curious about what he wanted to learn from the clothes; he just felt that the condoms that came with the Viagra purchase should be given to those who needed them more, since someone had died from the incident, so the condoms must have been of poor quality.

He reached into the outer pocket of his coat and found nothing except for a small inner pocket. However, the inner pocket seemed to hold something special; Li Lechen pulled out a small, transparent packet containing a pale yellow liquid.

I shook it and observed the liquid's flow; it resembled oil.

Then I remembered the day Luo Li fell flat on his back, stepping on oil.

There were also a few colorful balls about the size of marbles. Li Lechen crushed one of them, and it immediately turned into a large, mysterious pink feather.

Sure enough, these clothes were filled with magic props.

A sly smile appeared on Li Lechen's lips. He took out the "restoration reagent," restored the previously invisible condom, and then put it into the inside pocket of Liu Yu's coat.

Having successfully pulled off the prank, Li Lechen prepared to retreat.

"Knock, knock, knock." A knocking sound came from the door.

Who is it?

The key point is, I had just stepped inside when someone knocked on the door.

When Li Lechen opened the door, he almost fainted.

Sure enough, it's the same girl who started by selling simple juicers, then sold simple water purifiers, and is still promoting simple water purifiers right now.

The key point is, girl, you already knocked on the door of room 405 earlier, what's the meaning of knocking again now? Do you think you can fool someone else again?

The girl was also surprised, then gave an awkward laugh and said, "Senior? What are you doing in the dorm again?"

"Yeah, I needed to pee earlier, so I rushed back." Li Lechen shamelessly flirted with the girl.

The girl was stunned for a moment, and a blush immediately rose to her face.

"We're really going out this time, and no one will be in our dorm this afternoon, so please don't knock anymore," Li Lechen reminded him.

"Since we met you both times we knocked on the door, it proves we're destined to meet. Senior, you must buy two more simple water purifiers."

After a brief moment of shyness, the girl suddenly resumed her sales pitch.

Li Lechen was immediately overwhelmed: even this could be linked to fate, and then he "must" buy "two" more?

Seeing Li Lechen's lips twitch, the girl completely abandoned her momentary shyness and began to play the victim: "You see, it's not easy for me to do this sales. I've been trying to sell to everyone, and you just asked me and bought two, so I remembered to knock on your door again. If you buy two more, I might only be able to sell the previous two today... Actually, it doesn't matter if I don't sell anything. The key is those people who need help; they're really pitiful. Senior, what would you do if you didn't shower for a month in this hot summer?"

"???"

"Children in drought-stricken areas have trouble even getting drinking water, let alone taking a bath. Our money is used for this charity project. For every simple water purifier that you buy, children in drought-stricken areas can get three cases of bottled water."

"......"

"One box contains 24 bottles, three boxes contain 72 bottles. If you buy four simple water purifiers, it's equivalent to giving away 288 bottles of mineral water."

"......"

This girl's mental arithmetic skills are amazing!

"besides......"

"brush--"

Before the girl could continue, Li Lechen suddenly pulled out a hundred-yuan bill.

Li Lechen would be overjoyed if it only cost one hundred yuan to shut a woman up in the future. And right now, one hundred yuan has indeed achieved that.

Because a lot of time had been wasted, by the time she was about to leave, Zhou Mi sent her a message saying that she had already left the integrated laboratory and gone to the classroom to study.

So, Li Lechen stared blankly at the four simple water purifiers neatly arranged on the table.

Suddenly, something occurred to me.

So I entered the mall.

"Honey......"

"Give me a bottle of Class V water, a bottle of Class IV water, and a bottle of Class III water, and then try to deduct 3 points from my store points!"

Before the mall's sales assistant could speak, Li Lechen not only listed what he needed, but also made strict demands.

The sales assistant felt wronged: "I wouldn't have deducted 3 points from you in the first place, why were you so mean to me?"

It's just a robot, how could it feel aggrieved? Fortunately, Li Lechen's values ​​have been reshaped many times in the future live broadcast room, so he got used to it.

I got three bottles of water, but one point was deducted from my account.

However, after receiving the three bottles of water, Li Lechen discovered in his personal items that he had previously bought three bottles of water and had only used one of them, a Class 5 water.

The fifth type of water remains yellowish and turbid, like urine; when shaken, suspended matter is clearly visible. In contrast, the fourth type of water, while also somewhat turbid, contains significantly less suspended matter. The third type of water appears quite clean to the naked eye.

With Zhou Mi's previous water purifier, it could easily purify Class V water into Class I and Class II water that is safe to drink. However, it is unknown to what extent this simplified version of the water purifier cup can achieve.

Unscrew the cap on a bottle of Class V water and pour it into one of the water purification cups.

Water flowed from the upper part of the cup into the lower part of the transparent cup like a showerhead, and soon the entire bottle of water was poured in, barely filling the cup.

At first glance, although it's not quite drinkable, there are no visible suspended particles.

Quickly grab the four types of water for comparison.

In comparison, the water in the cup is significantly cleaner than Class IV water. Comparing it to Class III water, there is almost no difference; in fact, the water in this cup is even clearer.
