Screening Ninja Beasts

Does giving and receiving instruction count as effort?

Of course, it does!

Then what kind of reward should giving and receiving instruction receive?

Naturally, it should be that the students' speed of acquiring knowledge increases, and they can understand the knowledge being imparted very well!

Therefore, Kamiya Sanyō's ability to refine Chakra in 40 minutes might not be due to her incredible talent, but rather Kamiya Keiyun's Heaven Rewards Diligence taking effect.

Ruri the cat's ability to refine Chakra might not be because she's some kind of genius monster, but because Kamiya Keiyun is teaching her.

"Is that so?" Kamiya Keiyun fell silent for a long time, then his eyes suddenly lit up. "Is that so?"

So that's how it is, so that's how it is!

What is a World Secret Treasure? It's something with which one can dominate the world, something that the world's top powerhouses would fight to the death for!

How could the Heaven Rewards Diligence talent be so simple!

It doesn't just strengthen oneself; its power is all-encompassing!

"I have an idea!" Kamiya Keiyun turned and said, "Ruri, stop learning the Three Character Classic for now. I'll teach you, no, I'll teach you both the Transformation Technique!"

After telling the two the hand seals required for the Transformation Technique, Kamiya Keiyun watched them try.

Sanyō was fine; she was human and had hands.

Ruri was bewildered. It looked at its cat paws. "How... how am I supposed to form the hand seals?"

"Just do it!" Kamiya Keiyun said. "There's only one seal left. Even if you just go through the motions, with me here, you'll definitely learn it!!"

Ruri was a little confused. It had never imagined a cat would need to learn human hand seals. Ninja Beasts, after all, never cast ninjutsu; they mostly relied on their physical bodies.

But since Kamiya Keiyun had requested it, she still tried to form the hand seals with her paws.

Cats only have four paws, and they can't move flexibly. Forming seals designed for human hands was simply impossible!

But the Heaven Rewards Diligence system didn't care about that. If I taught diligently, there would definitely be results!

Then, Ruri, for some reason, felt a flash of inspiration, and the next second...

Bang!

It had transformed into another Kamiya Keiyun!

However, this Kamiya Keiyun was a bit small, only 20 centimeters tall. Compared to the nearly one-meter-tall Kamiya Keiyun, it was like the difference between a giant and a dwarf!

"It worked, haha, it actually worked!" Kamiya Keiyun said excitedly. "Increase your Chakra output, and you can become bigger. Become exactly like me!"

"Bang!" On the other side, Kamiya Sanyō had also succeeded!

However, she had transformed into a Kamiya Keiyun who was 1.4 meters tall. The young boy's appearance with a 5-year-old child's face looked a bit strange.

But that didn't matter. What mattered was that Kamiya Keiyun's guess was correct. Heaven Rewards Diligence indeed had miraculous effects on teaching!

"Sister, try shrinking your body to be the same as mine!" Kamiya Keiyun said. "I'll teach you the Clone Technique next. Sister, try turning your clone into my appearance!"

It was still the principle of saturated rescue. He intended for Ruri to transform into him, but if Ruri couldn't, Sanyō would have to do it.

"Right, don't try it here!" Kamiya Keiyun remembered that Konohagakure ninjas often climbed onto other people's roofs. If someone glanced down, everything would be exposed.

Although he didn't know why, his senses had become much sharper, but some ninjas' charging speed was too fast for his senses to react.

Yes, he was talking about Hatake Sakumo.

"You two go back inside and practice!"

As for Kamiya Keiyun, he first needed to know the activation time and range of this Heaven Rewards Diligence.

Logically, after teaching the Clone Technique, Heaven Rewards Diligence should ensure that the two of them could learn it.

But now Kamiya Keiyun was on the first floor, outside the house, while they were on the second floor, inside. Was Heaven Rewards Diligence still active?

Meanwhile, Kamiya Keiyun started catching insects in the yard again.

The yard wasn't large, as it had a patch of grass with quite a few insects. There were also goldfish in the pond.

Kamiya Keiyun caught a grasshopper, an earthworm, an aphid the size of a millet grain, an ant, a praying mantis, and a horsehair worm pulled from the praying mantis's abdomen.

Adding the goldfish from the pond, there were a total of seven targets.

He fixed them to a wooden board with tape. The goldfish were taken out and placed in a basin, and then Kamiya Keiyun said to them, "From now on, I will teach you the Chakra Refining Technique!"

With that, he recited the Chakra Refining Technique taught by his teacher. Fearing that one recitation wouldn't be enough, he recited it seven times.

Then, Kamiya Keiyun began to observe the changes in the seven animals and insects.

First was the aphid. He had only recited it three times when he noticed the aphid stopped struggling. After seven recitations, when he observed it again, he found the aphid had died.

"?" Kamiya Keiyun was speechless. He had only lightly stuck the aphid to the tape; how could it have died!

Looking at the ant, there was no sign of it refining Chakra. It was even kicking its legs and struggling to escape.

The earthworm, grasshopper, praying mantis, and horsehair worm were the same. They were all struggling, all trying to escape.

"None of them worked?" Kamiya Keiyun frowned. "Goldfish, you have to show some effort!"

Kamiya Keiyun looked at the goldfish, only to find it swimming around, showing no signs of refining Chakra.

"So, why is that? Heaven Rewards Diligence should be able to improve teaching efficiency!" Kamiya Keiyun thought for a moment, then considered another possibility.

Intelligence.

Could it be intelligence? These animals have no intelligence to speak of, so naturally they can't understand what Kamiya Keiyun is talking about. They don't even think Kamiya Keiyun is lecturing; they just think he's performing an execution.

Ah, a sonic execution.

You have to understand, the reason cats can learn is first because he used chakra to develop their brains, and second, cats are inherently intelligent and can understand Kamiya Keiyun's intentions to a certain extent.

Kamiya Keiyun held down the earthworm, still holding some expectations for it, as its abilities would be needed for his future plans.

He channeled chakra into the earthworm's body, and then...

BOOM.

Kamiya Keiyun stared at the earthworm, now blown into several pieces and devoid of life, and fell silent.

So, the meridians within this creature are so delicate that even the thickest parts can't withstand my power?

What a shame. It seems I'll have to find a substitute for the earthworm.

"So, the prerequisite for activating Heaven Rewards Diligence is that the animal must be intelligent enough to understand my lessons, and its chakra meridians must be thick enough to withstand my preliminary development. Does that mean it still has to be a large animal?" Kamiya Keiyun shook his head. He liked large animals, but not right now.

He needed to assassinate, not draw attention.

He needed small animals.

Cats were already quite large. If he kept too many, they might attract the attention of ninjas. He was a ninja himself and knew all too well how sharp a ninja's senses were.

Besides, even though cats don't eat much per meal, if he kept too many, he wouldn't be able to afford it.

An animal smaller than a cat, yet intelligent enough, and not attention-grabbing, did such a thing exist?

Indeed, it did.

First, there were rats.

Second, there were crows.

The intelligence of rats needs no further explanation; everyone knows it. Look at Jerry, look at Ratatouille.

It's generally believed that rats have the intelligence of an 8-year-old child. On social media, there are rats that can do housework and play basketball. Some rats can even play platformer games; there are bloggers who specialize in making videos of rats playing platformer games.

Crows are even more remarkable. The story of "A Crow Drinks Water" is written in elementary school textbooks!

Crows can even make tools, store tools, and possess logical thinking and reasoning abilities. Similarly, crows are adept at escape room challenges.

Animals like squirrels and magpies are also intelligent, but squirrels' distribution and concealment are not as good as rats', and magpies' range is not as extensive as crows'. Moreover, rats and crows are easier to keep, so Kamiya Keiyun discarded the other two.

As for rats and crows, which one to choose?

Of course, he wanted both! Rats would manage the ground, and crows would manage the sky, for all-round surveillance!

If possible, Kamiya Keiyun also wanted to get an amphibian, to complete his sea, land, and air ninja beast team.

However, he was a bit afraid of amphibians, so he could put that aside for now.
