"Come, come, can you speak?" Kamiya Keiyun first injected Chakra into the rat's brain.
"Squeak squeak." The Black Rat was clearly much smarter, but it didn't show any ability to speak.
"Is it because it's too small?" This rat was only 6 centimeters long, and it was obvious it hadn't reached adulthood, perhaps only one or two months old.
It was normal that it couldn't speak.
Besides, Kakashi had also said that not all Ninja Beasts could speak; some could and some couldn't, which was normal.
"But I want a rat I can communicate with. If we can't communicate, it'll be troublesome. I can't just gesture, can I?" Kamiya Keiyun whispered, then turned to Ruri, "Ruri, wait a moment, I'll wash this rat before giving it to you."
"No!" The rat in Kamiya Keiyun's hand hurriedly spoke.
No matter how many times he heard it, Keiyun found it incredible. He just injected a bit of Chakra, so why could it speak!
After all, in Xianxia novels, even demons had to refine their "bones" to speak!
However, it wasn't necessarily true. Some worlds had very low levels, but the demons within them could all speak without transforming, like the Sky-Swallowing Python.
"I wonder if there are any research institutions that specifically study the mysteries of Chakra. But even if there were, given this world's attitude towards suppressing knowledge, I might not even qualify to learn." It would be better to start one himself.
It didn't matter if there were no scientists; he could cultivate them himself. Kamiya Keiyun was only 5 years old this year. If he started cultivating them now, by the time he was an adult, the scientists he cultivated would be ready to be put to use.
"Can you communicate now?" Kamiya Keiyun asked.
"Y-yes, please don't kill me," the Black Rat said tremblingly.
"Since we can communicate, I won't kill you. I will teach you the Chakra Refining Technique, but in exchange, you must work for me from now on!" Kamiya Keiyun said.
"This..." The Black Rat hesitated. How to put it, it yearned for freedom.
"Food and lodging provided, 8 hours of work per day, with 3 hours of overtime allowed. Your work can earn you all sorts of Ninjutsu, which can make you even stronger!" Kamiya Keiyun said with a tempting tone, "Or, do you want to go back to your previous ignorant life?"
He was certain that no life could resist the temptation of intelligence. All the beauty and money in the world couldn't compare to superpowers like photographic memory and overclocked brains.
The Black Rat quickly shook its head. How could that be!
It was originally just an ordinary rat, living in ignorance before, knowing nothing, only living for food and survival.
But it was different now. It could think, it could perceive the world, and it could finally contemplate the meaning of life!
Living in a cage for a long time, then returning to nature; it was probably a feeling like this.
With such a feeling, who would want to return to the days of digging in the dirt for food, while constantly living in fear of being caught at any moment?
"May I ask what my job will be?" the Black Rat asked. "After all, I'm just a rat. If the work is too difficult, I might not be able to handle it."
"Can you dig holes?" Kamiya Keiyun asked.
"Of course, that's my specialty!" the Black Rat quickly nodded. Although it was a Roof Rat, houses in the past were mostly made of earth, and they could still dig.
While not as professional as moles, they were still good at digging.
"Then your current job is to dig a tunnel leading outside Konohagakure!" Kamiya Keiyun thought for a moment and said, "The Ninja of Konohagakure have sensitive senses. To avoid them discovering it, this tunnel needs to be dug deep. Let's start with a depth of one hundred meters!"
The Black Rat was silent for a moment, then asked, "One hundred meters, how tall is that?"
"About one hundred of me tall!" Kamiya Keiyun said, "By the way, do you know how big 100 is?"
"I didn't know before, but I do now!" The Black Rat thought for a moment and asked, "Then, can you put me down and let me go back to being my rat self?"
"What do you think?" Kamiya Keiyun smiled at Ruri beside him. Ruri very cooperatively jumped onto the table, her cold gaze fixed on it.
Such a look would only be considered cute by humans, but to a rat, it was a definite death stare!
"This..." The Black Rat swallowed, right. Where could it go back to? This cat lived so close by; it might be caught and eaten tomorrow if it went back today.
"Um, I have two older brothers and three younger sisters. How about I go back and call them too? I don't think I can finish this job alone." the Black Rat said.
"We'll talk about that later. First, you need to learn the Chakra Refining Technique. Otherwise, without my Chakra to sustain you, you'll return to your previous ignorant life!"
"Okay!"
"Oh, right, I'll give you a name too!" Kamiya Keiyun remembered. As a naming enthusiast, how could he allow his subordinate to not have a name!
"Okay!" The Black Rat nodded. It didn't care.
"Then, from today onwards, you shall be called Beibei! This name is not ordinary. It's a Sky-Swallowing Rat, with an immense appetite, capable of swallowing the sky. If you can reach even one ten-thousandth of it one day, it won't be a disgrace to the name."
"Huh?" The Black Rat's spirits immediately lifted, "Sky-Swallowing Rat?"
This name sounded extraordinary. I thought rats only stole rice to eat, but I didn't expect there to be such amazing predecessors?
"Of course, there are quite a few famous figures in your rat world. Sky-Swallowing Rat Beibei, White Day Rat Bai Sheng, White Fur Rat Lady Diyang who stole the oil lamp from the Buddha, Brocade Fur Rat Shui Bingbing, the lover of Marshal Tianpeng of the Heavenly River Navy, the all-knowing Jerry, the all-powerful Jerry, and Shuke who flies planes, and Beta who drives tanks," Kamiya Keiyun introduced seriously, "I can tell you their stories when I have time."
"Ah, this..." The Black Rat's small eyes blinked for a long time, then it suddenly said, "Then, can you give me a different name?"
"What, isn't Beibei grand enough?"
"It's grand, but since it's someone else's name, I'd rather not use it. I also want to be one of the names you listed, not a rat using another rat's name," the Black Rat said.
"Hmm?" Kamiya Keiyun was taken aback. This rat actually had a dream!
Amazing, truly amazing!
"Not bad, you're very good, much better than that lazy cat next to you!" Kamiya Keiyun nodded, "Since that's the case, with your black fur, let's take 'Hei' as your surname. With great ambition in your heart, wanting to stand alongside your predecessors' names, let's call you Hei Bei. I hope you aim high and achieve your dream soon!"
"Hei Bei, Hei Bei..." The Black Rat wasn't very enthusiastic about names at first, but after hearing the meaning behind the name, and then hearing this name, it liked it more and more, nodding repeatedly, "Yes, Master, I will definitely work hard and become famous soon!"
"Good, then first, refine some Chakra, and then I'll teach you how to strengthen your claws. Then we'll see if your digging efficiency improves after you become a Ninja Rat!"
