Bubble stretched out part of its body and drew some strange patterns on the ground. Nan Sheng looked at them carefully but was confused.

Seeing this, Bubble gurgled a few more times, then slowly crawled towards the hospital cafeteria.

Nan Sheng suddenly realized something and hurried to catch up, saying as they walked, "Are you trying to tell me that you like some of the food in the cafeteria?"

Bubble stopped in front of a swill bucket in the cafeteria and touched the bucket with his body.

Nan Sheng frowned and said, "Although this slop is leftover food from the cafeteria, it may not be very hygienic. We have to process it before giving it to you. Otherwise, you might get an upset stomach and won't be able to work."

Bubble explained: "What I mean is that we can all deal with these. When we clean up these garbage or food scraps, we are also replenishing our energy."

Nan Sheng was shocked and said, "What about cleaning up the filth and blood stains in the hospital..."

Bubble shook its body and made a series of gurgling sounds, as if confirming Nan Sheng's guess: "Gurgle, gurgle, that's right, those things are also a source of energy for us. We can clean them out efficiently, more thoroughly than ordinary cleaning methods."

Nan Sheng frowned slightly. Although the slime's abilities seemed very suitable for hospital cleaning work, it was still hard to accept the thought that they fed on these special things.

But he continued to ask: "After you clean up these, will there be anything left? Or will there be any smell or something?"

Bubble seemed to understand Nan Sheng's worries. It slowly moved to a stain nearby and quickly wrapped it up. After a while, the stain disappeared, and Bubble's body only changed color slightly, without emitting any strange smell.

It gurgled a few more times, and Nan Sheng seemed to hear it saying, "We digest these things very cleanly. There won't be any residue or odor. Don't worry."

Nan Sheng breathed a sigh of relief upon seeing this. He realized that Paopao did have his own unique understanding and planning for hospital cleaning work, and might really be able to become an effective member of the hospital cleaning team.

However, he was still somewhat interested in what was in those jars, so he asked Bubble, "What was the use of the liquid you secreted when you cleaned the hall yesterday?"

Bubble shook his body and said, "I don't know."

It then added: "Each time you cleanse something different, the secreted fluid will have different effects, and its color and properties will also be different."

After hearing what Bubble said, Nan Sheng became more curious. He squatted down and observed Bubble's body carefully, trying to find some answers from its transparent and constantly changing shape.

Just then, Nan Sheng's phone suddenly rang. It was Lin Lin calling. "Nan Sheng, how was the conversation with Paopao? Is there any new developments?" Lin Lin's voice came from the other end of the line.

Nan Sheng reported to Lin Lin in detail about the conversation she had with Bubble regarding food, cleaning ability, and mucus.

Finally, he added that there were ten other friends of Bubble who were not present.

Lin Lin pondered for a moment on the other end of the phone and said, "Regarding the ten slimes that haven't arrived yet, don't rush to decide whether to accept them. Wait until the performance of these twenty slimes is stable and good before making a decision."

"The most urgent task right now is to ensure that the details of the cooperation we've agreed upon with Bubble can be implemented smoothly. Let's set a seven-day internship period for now! If no other problems arise within seven days, all ten slimes will come together to sign the contract."

After Nan Sheng hung up the phone, she said to Bubble, "Bubble, Dean Lin said we can try to cooperate first. If there are no unexpected problems after seven days, we can sign a cooperation contract with your 30 slimes."

Bubble nodded in agreement.

Seeing this, Nan Sheng said, "Then let's discuss the workflow first!"

"We want you to start cleaning the wards every day, then move on to common areas like corridors and stairs, and finally to special areas like operating rooms."

“Is this order okay?”

Bubble thought for a moment, stretched out some tiny tentacles and gestured on the ground a few times. After careful observation, Nan Sheng found that it seemed to be adjusting the order, starting from the operating room, then the ward, and finally the corridors and other areas.

Nan Sheng asked in confusion, "Why do we have to start in the operating room? The cleanliness requirements there are very high."

Bubble began to explain again, and Nan Sheng tried hard to understand what it meant. It was probably saying that some special stains and energies in the operating room were more attractive to them, and after cleaning the operating room, their physical condition would be better and they would be able to clean other areas more efficiently.

Although Nan Sheng found it a bit strange, but thinking that slimes were different from others, she said, "Okay, let's try it in the order you mentioned."

“But if there are any issues, we may adjust them at any time.”

After Bubble agreed, Nan Sheng discussed with it some details about the use of cleaning tools (although slime itself is a good cleaning tool, some special areas may need to be combined with some conventional tools), how to deal with emergencies (such as when a patient suddenly vomits or an accident causes large-scale contamination), etc.

After some in-depth communication, Nan Sheng felt that the intention of cooperation between her and Bubble was becoming increasingly clear, and she was full of expectations and concerns about this unique cooperation.

Soon, seven days passed.

Everyone in the hospital was very satisfied with the work of the Bubbles.

Lin Lin called Nan Sheng into his office and said with a satisfied smile, "Over the past seven days, the slimes' performance has truly exceeded expectations. Whether it's the meticulous cleaning of the operating room or the routine cleaning of wards, corridors, and other areas, they've done an excellent job. We've received almost no complaints about cleanliness. It seems they're well-suited to this job."

Nan Sheng nodded in agreement. "Yes, Dean Lin. The bubbles work very diligently, and they can even adjust their cleaning methods based on the characteristics of different areas. The hygiene issues I was worried about haven't occurred. After they digested the stains, there's really no residue or odor."

Lin Lin frowned slightly and thought for a moment before saying, "In that case, let's follow our previous agreement and take over the remaining ten slimes and formally sign a cooperation contract."

"The contract should clearly stipulate their scope of work, working hours, food provision standards, and corresponding reward and punishment mechanisms to ensure the standardization and sustainability of the cooperation."

Nan Sheng replied, "Okay, Dean Lin. I'll go prepare the contract and inform Paopao of the good news."

When Nan Sheng found Bubble and told it that it could sign a formal contract and the rest of its companions could join, Bubble jumped excitedly, the mucus on its body swayed, and it made a series of cheerful gurgling sounds, as if celebrating this moment.

The yellow jet that was previously placed in the bag was completely eaten up by this group of slimes during the time when everyone had forgotten about it.
