Lu Suisui's face darkened as she looked at the reward she had obtained with great difficulty [the legendary all-purpose broom], because this broom was no different from the one she had just used to complete the task. Even the patterns on it were exactly the same. Looking at how hard she had worked to get such a broom, Lu Suisui was so sad that she wanted to cry.

Just when Lu Suisui was about to cry, the house was restored to its previous state because the mission was completed. Xu Xi and others who had been waiting anxiously outside found that the door could be opened, so they immediately opened the door and rushed in. They saw Lu Suisui still standing there safely, and they all breathed a sigh of relief.

Everyone was shocked when they were suddenly transferred outside for no reason. At that time, they all thought that they were suddenly forced to run outside because of the system that Lu Suisui mentioned. Later, they went to pull the door and found that the door could not be opened. They became more certain that it must be the system that Lu Suisui mentioned.

Looking at the situation, they knew that the mission had probably begun. Later, in order not to affect Lu Sui Sui's mission, even though they were worried, they did not force the door open. Later, seeing that the door was opened a corner, they thought that the mission must be over, so they hurried in.

However, seeing Lu Suisui's face full of despair, they all thought something had happened, and immediately surrounded her and asked her what happened.

As doctors, Xu Na and her team immediately began to prepare to examine Lu Suisui. At the same time, they contacted the RV parked in the open space outside to get it ready. They wanted to take Lu Suisui there for a physical examination.

The RV was prepared in advance. It was prepared for Lu Sui Sui's health. It has a total area of ​​116 square meters and is divided into two floors. The two floors contain a laboratory, a treatment room, a recovery room, a kitchen and a rest room. They had previously thought about building a house next to it to do those things, but after listening to Lu Sui Sui's description, they all agreed that the mission location may change at any time and place, so using a house would be of little use. Later, after much consideration, they chose an RV that can be moved anytime and anywhere as their base.

At this time, Lu Suisui, who heard the worried voices of Xu Na and the others, finally came to her senses. She looked at Xu Na, Xu Xi and the others as if she saw her own brother and sister, then pursed her lips and said aggrievedly, "This broken system, it cheated me. I worked so hard and the reward for my hard work was just an ordinary broom. It is exactly the same as the broom in my house, even the pattern is exactly the same. Moreover, when I asked the system, the system ignored me and kept pretending to be dead." Lu Suisui became more and more angry as she spoke, and threw the broom in her hand aside, then turned her head away angrily, not looking at the broom that made her sad.

At this time, the others who heard Lu Suisui's words all smiled and asked, "Are you okay? Did the live broadcast make you feel uncomfortable?"

"Well! I didn't find anything about this, and I don't know if it was my illusion, but I felt so relaxed and energetic." Lu Suisui looked at his body and answered.

Hearing Lu Suisui say that she was not feeling unwell, Xu Xi and the others felt relieved. However, they felt that they should still let Lu Suisui undergo a full body check-up before they could be completely relieved.

Lu Suisui accepted Xu Xi and the others' concern and didn't reject their offer, because she knew they cared about her. However, before doing so, she decided to study the Interstellar Broom. "After all, it's made by Interstellar, so how could it be just an ordinary broom?" She also remembered it very clearly. It was called the All-Purpose Broom.

However, Xu Xi and the others had different opinions on Lu Suisui's experiment with the interstellar broom. They thought Lu Suisui should get a physical examination first. They were afraid that there might be some unknown virus in the interstellar mission that would harm Lu Suisui's body.

However, Lu Suisui was stubborn and would not change her decision once it was made. Then she thought of the things she had encountered during her previous missions. She had worked so hard to get the reward, and she would not feel at ease until she got the results of the experiment.

Xu Xi and the others had no choice but to agree with Lu Suisui's decision as they couldn't persuade her.

Lu Suisui picked up the Interstellar Universal Broom that she had thrown aside from the ground. This broom looked exactly the same as the broom she used at home, with a blue handle and black bristles underneath. Lu Suisui picked it up and gently swept the ground.

Just as Lu Suisui touched the broom to the ground, a transparent screen appeared on the broom. Lu Suisui moved closer to the screen and saw the words "Do you want to start purifying the air?" with two options beside it: "Yes" and "No."

Lu Suisui looked at the choice and directly chose "Yes". Then the picture on the transparent screen suddenly changed, and other words appeared. The other words read "According to monitoring, the air quality where you are now is D. There are six levels in total, namely A, B, C, D, E, and F, six air quality levels." There was a button under each of the six air levels. Lu Suisui tried to press the "A" level air purification button.

After Lu Suisui made her selection, a message appeared on the transparent screen: "The current conditions do not meet the requirements for purification to Class A. Please select again."

Looking at the prompts above, Lu Sui Sui had no choice but to make a new choice. At this time, Lu Sui Sui suddenly found that there was another line of words at the bottom of the screen. Lu Sui Sui looked down and found that it said, "Requirements for each level of air purification." Looking at those words, Lu Sui Sui quickly clicked on the so-called requirements.

Then she found it written:

"Air evolution is divided into six levels: A, B, C, D, E, F"

A-level purification requirements: For every ten tons of garbage, a space of 1 meter long, 1 meter wide, and 1 meter high can be created. [After A-level purification, the human immune system will be greatly improved, and the quantity of all cultivated plants will be maximized. Harmful substances will be transformed into substances beneficial to the human body under the influence of A-level air. After obtaining A-level air, the right to use it is permanent.]

Looking at the benefits written on it, and the fact that the usage period is permanent, Lu Sui Sui was overjoyed and wished she could have that A-grade air right now. But when she saw the requirements to obtain it, she felt a little discouraged. Not to mention the astonishing amount of ten tons of garbage, just to say that it would take one completion to purify one meter long, one meter wide, and one meter high, which together formed a square. There was not enough space for one person, and two more tests were needed before one person could stand. There was no way, looking at the strict requirements, Lu Sui Sui could only look at other levels.

Then Lu Suisui moved his eyes to the bottom of Class A and above Class B. There it read, "Class B purification requirements: For every five tons of garbage, a space one meter long, one meter wide, and one meter high can be purified." "After Class B purification, the human body's immunity will be improved, and the success rate of plant and crop cultivation will be increased. Class B air can consume half of the harmful substances. The other half, unable to come into contact with Class B air, will be divided into two spaces, which will not interfere with each other. The right to use Class B air is permanent."

Looking at the requirements for Class B air purification, Lu Suisui felt that this could be considered, because the size was similar to Class A, both were square, and the 5 tons of garbage looked okay overall. After all, in today's society, there was a lot of various types of garbage generated, and the usage rights were permanent. However, what made Lu Suisui feel most bad was that it said that only half of the harmful substances could be consumed, and the other half was isolated on the other side. In other words, two extremes would be formed, one with extremely good air and the other with extremely bad air. If this continued for a long time, it would cause great harm to the human body. So after thinking about it, Lu Suisui decided to look at other options, which was the last one she could choose.

The air quality here is currently rated D, and the options she can choose from are A, B, and C.

Thinking of this, Lu Suisui looked at the C-level air purifier. The front was similar to the above one, but when she saw the requirements, Lu Suisui raised her eyebrows. This requirement was too low. It said that 100 kilograms of garbage can be purified. It was one meter long, one meter wide, and one meter high, the same square. The usage rights were also permanent. However, she was a little stunned when she saw the benefits after using it.

The benefits of using it are not bad. In Lu Sui's opinion, the benefits are even better than those of Class A. It says on it, "The land after Class C air purification will be optimized to the best. No matter what is planted, it will be successful. It can also be used in deserts. Place Class C air in the desert. Class C air will optimize the desert land and make the desert land suitable for planting. In addition, after using Class C air purification in the desert, it can resist a series of disasters such as sandstorms." After reading these introductions, Lu Sui Sui also noticed that there was another small line of words written at the back, which said that it is mainly suitable for desert areas. Please use it with caution in other places.

Looking at the small line of words, Lu Suisui was a little confused. "Could it be that it can't be used in cities? But it doesn't say why it can't be used in cities, nor does it say what would happen if it were used in cities?" Lu Suisui, lost in thought, decided not to purify those items yet. He would go out and discuss it with the others before making a decision and then try it out.

"She definitely had to use it. After all, the benefits were substantial. Just the lowest-level C-level purifier alone, with its desert-purifying benefits, made her eager to purify it right away. But for now, she had to take it one step at a time." Thinking this, Lu Suisui immediately shared everything she had just witnessed with Xu Xi and the others. She also gave them the items she had picked up during her sweeping mission, asking them to take them for testing.

If you like it, please leave more comments. I have also opened a few pre-collections. If you like it, you can collect it. I will post the article based on the collection.

Prepayment 1:

[She is the only Omega]

Yu Qiman is the most perfect Omega in the galaxy. Ever since she became conscious, she knew that she was born to assist those powerful Alphas and rely on them to survive. Even though she has learned all kinds of skills, she cannot escape the fact that she is a weak Omega. She thought it would stay like this forever, but she didn't expect that she would actually travel into an ancient novel from thousands of years ago.

She was very satisfied after she became the female supporting character Yu Qiman, who was hated by everyone in the novel. What made Yu Qiman happy the most was that there were only men and women here, and there were no so-called Alphas. She did not have to rely on them to survive, and she was no longer the weak Omega.

But she didn't know that there were no Alphas before because there had never been Omegas. Her appearance awakened the wild instincts of those men.

Note: Everyone loves the heroine, but she loves no one. She only wants to use everything she has learned in the interstellar world, develop it, let the people enjoy it, and then find ways to improve the technology of Blue Star, as well as medical care.
