[New insight, New World]

With that one hour later, the room was filled with moans, squealing, and screams in Yuriko's pleasure.

Which ended with Yuriko's womb being filled to the brim with Ren's cum and passed out with a silly smile on her face like her daughter.

~~~~~~~^~~~~~~~

After feeling satisfied with the mother and daughter pair, Ren went to get ready to meet the others.

When he reached the backyard Ren saw that everyone had gathered there and were waiting for him.

*Cough*

Ren cleared his throat and got their attention before saying.

"Alright, if you are all ready we can leave now for Fujimi Academy."

Those who heard this nodded and carried their belongings respectively.

As for Ren's women, they share their baggage by helping each other.

"Hmm? Where are Yuriko and Saya?" Shizuka asked and tilted her head.

"That's right I didn't see them... I thought they were with you Ren." Yuki said.

While Rika was grinning as if she already knew the reason they weren't seen.

"Looks like they can't walk for a while~" Rika said.

Shizuka and the others were confused by her meaning but a moment later realized what Rika meant and their cheeks immediately turned slightly red.

"As expected of my husband, when in bed he becomes a beast~" Rika teased Ren.

Ren hearing this smiled proudly because besides he lasted long in sex with them even to the point of fainting, it also meant he could satisfy them.

Nothing pleased him more than satisfying his wives, and Ren also felt satisfied. That way both parties are equally happy.

"Yuriko and Saya are sleeping. We can go to Fujimi Academy first."

"Don't worry I'll leave one of my clones to take the two of them later to Fujimi Academy to catch up with us when they both wake up." Ren added.

Hearing that they nodded and went with Ren to Fujimi Academy leaving Yuriko, Saya and his clones.

Several hours later Ren and the others finally arrived at Fujimi Academy.

But Ren felt strange when he saw that there were several people standing at the school gate.

Among them Ren saw those who were dressed as soldiers like Rika her three female friends.

"Sakura, Kagami, Izuki..."

Rika who recognized them called out and then approached them.

"Rika, thank you for telling us the news. Once again I'm sorry for laughing at you when you told us that there would be an epidemic like this." a man named Kagami said while bowing.

"Rika, thank you and sorry for not trusting you

a girl named Sakura said.

Rika who saw her comrades like this felt pity and said.

"Forget it, it's already past anyway."

While Rika was talking with her friends, Kagami approached Ren and bowed before saying.

"Thank you for helping us and our family Ren-san."

"Eh?" Ren was stunned and confused.

Rika, who saw her husband stunned because of her friend's behavior then approached him.

"I told them about your clone running around this town helping people and killing zombies, and one of the people you helped were Kagami's parents." Rika said.

"O-oh...you're welcome." Ren said.

"Okay, oh yes Kagami where are uncle and aunt?" Rika asked.

"Because things were safe, they decided to stay at home." Kagami replied.

Rika who heard that breathed a sigh of relief and said.

"Thank goodness..."

Then two pairs of parents approached Ren who was talking with Kagami and Rika.

"Thank you for saving us!" a middle-aged man and woman bowed and said.

'Who else is this!? why do people keep thanking me.' Ren thought.

"Ren-kun thank you for saving our family, this is my father and mother." a girl Ren knew named Aiko said.

Another woman then approached Ren and said.

"These two people are my parents Ren, thanks again... oh by the way my name is Izuki."

"Ah... you're welcome." Ren said.

After exchanging gratitude they all entered the school gate.

Arriving at the school field they could see bloodstains everywhere but they didn't see the bodies of the zombies there.

Kyoko who saw this felt strange and approached Ren before saying.

"Where are the zombie corpses? As I remember when we wanted to get out of school and head to your house, you killed lots of zombies without exception here."

"My clone cleaned it up when we all got to my house." Ren said.

"You move really fast... looks like you planned it..." Saeko said.

Hearing that Ren chuckled and said.

"If I'm not fast how can you call me a ninja, right?"

"I have a feeling you're not a ninja..." Rika said quietly.

"Un. I also feel that way..." Shizuka who was beside Rika chimed in.

But Ren who heard it just smiled mysteriously.

Then Ren found a position to set up his big tent, enough for his woman to sleep with him.

When finding a place, Ren then took out a large tent and other necessities from nothing.

Of course it surprised everyone present, and made them ask Ren.

"Okay, I'll explain later. First of all, who wants to learn about ninjas, please line up..."

Ren paused for a moment then continued.

"But before that we prepare tents and other needs first."

Hearing Ren's words, people immediately set up tents on the sidelines and prepared their own needs.

~~~~~~~~

~~~~~~

Around 16:30 PM, people had gathered with Ren in the field.

Yuriko and Saya were also seen having come to Fujimi Academy and were sitting in the field with the others.

"First I will explain ninja to you guys." Ren said.

'I have to come up with another story…Haahh...' thought Ren.

Then seeing everyone gathered and sitting on the field watching him carefully Ren nodded and continued.

"In this day and age, people with the blood and techniques of a ninja have disappeared from this world. I'm not sure why, but as far as I know I'm the only real ninja clan that still lives in this world."

"In the era of the ancestors, ninja were usually hired as guards or assassins by the daimyo or other conglomerates under the name Shinobi."

"Once upon a time during the Bakumatsu era and before Shinobi had their own clans, each Shinobi clan had its own specialty."

Ren wanted to continue but seeing Rika raise her hand, Ren paused and nodded towards Rika.

"Then which clan are you from?" Rika asked.

"I come from the Senju clan, the Senju clan itself has its specialty, namely a bloodline related to nature which is very strong. It's easier for the Senju clan to be able to do this..."

Ren paused then made hand seals and said.

{Mokuton : Mokujoheki}.

A giant wooden dome shaped like a quarter ball suddenly appeared to cover the sun shining on them.

Seeing this giant wooden dome, people were surprised and curious, then they began to examine and touch the giant wooden dome.

Even the people who were talking in the tent came out of their tent and examined the giant wooden dome.

Moments later Ren canceled his jutsu, the wooden dome returned to the ground and disappeared from their sight.

"This is the privilege of the Senju clan." Ren said.

Hearing Ren's words they looked at him in awe and sat back down.

People who didn't want to participate in the training finally joined and sat down to hear Ren's teachings.

As Ren was about to continue his teaching, Saya raised her hand and asked.

"Can all Shinobi do the same as before?"

"No, in the beginning it was all only the Senju clan could do." Ren replied.

"Then what about the other clans? what privileges do the other clans have?" this time it was Yuriko who raised her hand and asked.

Hearing that Ren smiled and said.

"Very good question dear."

The people who heard that were shocked and looked at Yuriko, especially Kiriko and Yui who narrowed their eyes at Yuriko.

'H-he likes older women!?' Kiriko thought.

While Yui smiled and thought.

'I have a chance.'

Yuriko who was called that by a much younger man than herself in public still felt a little embarrassed and made her cheeks blush slightly.

While Saya pouted her cheeks playfully.

Seeing this Ren smirked and decided to cheer her up later by sending telepathy to Saya, which made her blush in the end.

*Cough*

Ren cleared his throat and said.

"Other clans certainly exist, and they are named, Yuki Clan, Uchiha Clan, Kaguya Clan."

"If my clan, Senju Clan has natural and wood elements, then the Yuki Clan has the ice element, the Uchiha Clan has eyes that can kill their enemies and the Kaguya clan has the ability to manipulate bones either into weapons or means of protection."

"If there are elements of Wood and Ice then there are elements like water, fire, earth and others?" Yuuki asked.

"That's true. But elements like Water, Fire, Wind, Earth, Lightning, are the basic elements that all Shinobi can use." Ren said and smiled.

"Doesn't that mean you can also use elements other than Wood?" Shizuka asked.

"Of course."

Ren then made hand seals and said.

{Katon : Gokakyu No Jutsu}.

A huge fireball shot out of Ren's mouth towards the sky before finally disappearing.

{Doron : Doryu Heki}.

The dragon made of earth flew towards the sky before being crushed.

{Suiton : Taihodan No Jutsu}.

The water cannon that came out of Ren's mouth hit a tree and destroyed it.

{Fuuton : DaiToppa}.

A strong wind formed a vortex in front of the people, When all objects wanted to fly Ren canceled his Jutsu.

Everyone present who was paying attention to the technique and its effects opened their mouths wide while looking at Ren.

"Those were all the elements mastered by ninjas." Ren said.

Silence... everyone just fell silent and stared at Ren as if he was a monster.

In that silence, Rei could be heard asking and waking everyone up.

"Ren then what about lightning?"

"Oh I forgot..."

Ren then made hand seals and said.

{Raiton : Raikiri}.

A surge of Lightning flashed across Ren's right hand before finally dissipating.

"For a shinobi to master the elemental techniques suited to them is the best way to save their life..."

Ren paused for a moment then continued.

"But before that I will tell you about the beginning of why those Shinobi were able to cast various techniques like that."

Ren then explained about {Chakra}, how to train {Chakra}, and how to perform hand seals on them.

Everyone then perked up their ears to listen and pay close attention, what is Chakra, how to train it, and how to do hand seals.
