Leave the Blue Sea Star store. Twenty minutes later, Jiang Yichen was alone in his office on the third floor of Dingxiang Garden, he closed the door and began to conduct the great scientific practice.

He took out the plastic bucket with the dirty seawater and put it in the corner. Then unscrew the lid of the small oil bottle that I had just brought from the kitchen and pour some vegetable oil into it. In this way, it is both sewage and oil layer, which is more difficult, and it is a great test of the purification ability of purple ice.

Then two triangular female mussels were taken out of the space, and after being confirmed to be alive, they were invited into the bucket.

"I'm sorry, let's do it with the two of you. If something happens, it will be honorable to dedicate oneself to the great cause of science. ”

He muttered as he took out another piece of purple ice, broke a piece as small as a fingernail, and threw it into the dirty water.

The next thing is to wait. Taking advantage of this, he paced slowly around the room, thinking about what else he should do to supplement the substance.

Fifteen minutes later, he walked over to the plastic bucket, bent down and took out a flashlight to light it in.

He was delighted to see that the water in the bucket had become crystal clear, and not only the original dirt had quickly deposited, but even the oil added to it had disappeared without a trace.

The two triangular female mussels are lying at the bottom of the barrel, each with their shells open, not only alive, but also looking very comfortable.

Hehe, at first glance, purple ice is not only super effective, just the volume of a fingernail can purify half a bucket of sewage, but it is also harmless to marine life. It's a good thing.

In addition, looking at this fast-acting posture, it may be possible to reduce the amount of purple ice again.

Well, wait and see, the time is still too short to be hastily determined.

Time continued to pass until more than an hour later, when the kitchen guy brought his dinner to the office. The triangular female mussel still does not show any abnormality.

Whew, the purple ice is really powerful, and the experiment has been initially successful. Jiang Yichen breathed a long sigh of relief, his heart was full of joy, and he sat back in his office chair. I pondered things while eating.

The real yàn can continue, and at the moment the bucket is only filled with domestic sewage. What about industrial wastewater, which contains various oils, chemicals, or heavy metal ions? You must know that there are a lot of these substances in the offshore seawater, and it seems that it is worth trying.

However, on second thought, it is too cumbersome to find that the high concentration of industrial wastewater is obtained from the sewage outlets of some factories, and a complete set of laboratory equipment needs to be purchased to carry out the inspection.

Forget it, simplify the procedure, or just find the common things around you to do the real yàn, so that seeing is clean and the mother mussel can survive in it. After all, I don't want to do this profession specifically.

Next. Jiang Yichen stayed in the city for two days. During this period, kitchen wastewater, lubricating oil, detergent, etc. were used to further test the purification performance of purple ice.

The situation is quite good, no matter what challenges are encountered, Purple Ice is basically to clean up one by one, clean and neat. Shows great ability.

In addition, the amount required is very small, and although it is not possible to arrive at an exact number without limit testing, the conclusion is generally that there is no problem.

The female mussels used to act as the actual mice, as well as some clams from the kitchen, were alive and healthy, and nothing unusual had occurred.

Jiang Yichen once wanted to go to the flower, bird, fish and insect market and find a seawater landscaping tank to try, because there are tropical fish and live corals in it. The requirements for water quality are even higher.

But this idea was quickly dispelled, for the simple reason that the seawater tank ecosystem is expensive, often priced in tens of thousands of dollars, and it is almost impossible for any boss to let you experiment. It's probably boring to get there.

But the results so far have made him very satisfied. The No. 3 Purple Ice Cave also became a priceless treasure in his eyes. Moreover, the purple ice inside, like other spatial ice, has the ability to regenerate, which means that as long as the frequency of access is controlled, it can be endless.

The next step is to go to Yunsha Island for practical application. To this end, he told Director Shen of the logistics department to buy a new batch of iron buckets, which were placed in the space purple ice cave to hold ice skates to improve the efficiency of regeneration and harvesting.

With the expansion of the business scale of Dingxiangyuan and Koufuduo, as well as the increase in the frequency of production and transportation on Yunsha Island, the logistics department of only one person has been busy. So after getting Jiang Yichen's approval, the establishment was expanded, and an assistant was added to Director Shen, and Director Shen finally got rid of the situation of the commander of the light pole.

When I returned to the rental house on Kwong Ping Street in the evening, I ran into Ma Detao, whom I hadn't seen for a while, who was wearing a single vest and was leaning on the sofa in the living room to watch TV.

"Hey, your kid has been missing for so long, why do you remember to come back? I'm still worried, just now it was reported on TV that a boss was kidnapped and demanded a ransom of 5 million. Later, I almost tore up the ticket. When Ma Detao saw Jiang Yichen, he had a pretended surprised expression on his face.

"I went on a trip to the field. You stinky crow's mouth, do you want me to make a good job? Jiang Yichen frowned and said, this tall guy still has that stinky virtue.

He changed into his slippers and went to the living room and sat down.

"I'm kind enough to remind you, there are many people who hate the rich in society now, and you are the big bosses, and if you are not careful, you will let the buddies on the road be targeted, oh, I heard that in the south, this is called a fat pig, hehe." Ma Detao crossed Erlang's legs and said with a big grin.

", what a big boss, have you ever seen a big boss rent a house to live in?" Jiang Yichen shook his head, reached out and took a peanut from the plate on the coffee table, broke it and threw it into his mouth.

"That's right, the wealth is not exposed. Hey, by the way, when it comes to this house, I'm on fire. Lao Liu Touer only promised not to raise the rent this year last time, but he changed his words two days ago, saying that prices have risen sharply, the family is living in difficulty, and his grandson can't afford to pay the sponsorship fee for school, so he almost didn't say that he couldn't open the pot. The lease will be renewed at the end of the next month, and 400 will be added every month. Damn, talking is the same as putting p. Ma Detao then remembered this stubble and immediately became angry.

At present, the monthly rent of this two-bedroom house is 1,600 yuan, plus 400 is 2,000.

"Forget it, a few hundred yuan, don't worry about others, it's not easy for anyone these days." Jiang Yichen responded lightly.

In today's big cities, it is common for rents in urban areas to rise year by year, and this is not too large and acceptable.

Since graduating from school, in order to take care of Ma Detao's financial conditions, his rental career has been long enough. But there is no banquet in the world, and it is inconvenient to rent a house after all, and in a few days, I am afraid that I will have to buy a suite in Lingjiang and move out. (To be continued)
