Teaching the Ninja Cultivation System

"Well, let me teach you first the techniques for refining energy in this system. This energy is called Chakra. Listen carefully: Chakra is a kind of energy produced by the perfect fusion of spiritual energy and physical energy. It is generally used to perform Ninjutsu, and can also be made into threads to bind opponents or cut substances that are also composed of Chakra."

Simply put, Chakra is the energy necessary to use Ninjutsu. This energy is roughly composed of: 1. Physical energy absorbed from each of the 130 trillion cells in the human body; 2. Mental energy cultivated through extensive training and experience.

In other words, so-called "Ninjutsu" is the will to extract these two energies from the body, refine them (this is called creating Chakra), and then activate them through the process of "Hand Seals"!

The specific cultivation method is as follows: First...

Issui explained all the methods of Chakra extraction that he knew.

Krasil listened intently to Issui's explanation, growing more excited and thrilled with each word. Unlike the wizarding cultivation system, this method was accessible to almost everyone. While warriors existed in this world, they only knew how to train their bodies, not how to refine the energy within their cells. In this way, all warriors could become the ninjas mentioned by His Highness the Divine Child. Human warriors comprised two-thirds of the total human population. If all of them could cultivate, even if they only reached the level of Chunin, two-thirds of humanity as Chunin could overwhelm an army of demonic beasts. Furthermore, ninjas could unleash five elemental escape techniques—truly astonishing.

After explaining the methods and techniques of Chakra refinement, Issui said to Krasil, "Try refining one Chakra and see if you can cultivate energy from it."

Krasil nodded hastily, closed his eyes, and began refining the energy within his cells and his own spiritual energy. Gradually, an hour passed, and Krasil finally refined a trace of Chakra. Having cultivated for many years, as the strongest level-five warrior in Blue Mountain City, his body was already extremely strong. The energy within his cells was gradually refined, and like a dam opening its valve, it accumulated more and more. Years of cultivation had caused his physical energy to accumulate to an extreme point; once refined, it all surged forth, forming a massive circulation within his body.

Issui nodded. "That's right. It seems the samurai of this world just lack guidance to refine the energy from their physical training. Judging from the energy leaked out by Krasil, he has already reached the initial level of Genin. After training for a while, becoming Chunin or even a Jonin won't be a problem."

After cultivating for a while, Krasil opened his eyes and excitedly thanked Issui, saying, "Thank you so much, Your Majesty. Please come with me to the guest room to rest. The leaders of the three kingdoms and the Demigod are estimated to arrive here in about a day. I have already instructed the servants to prepare the best food and water. It is already evening, so please have dinner with Your Majesty and your lady, and then rest early."

Issui nodded. "Okay, oh, by the way, my wife doesn't speak the language here..."

Suddenly, Issui remembered that Bai didn't know the language here. He hadn't known how to speak the language before, but the old man Bruton took out a leather scroll, said a few unknown incantations, tore open the scroll, and he immediately learned and became proficient in the language. It was quite amazing.

"Oh, I see. The wizards invented a universal language scroll that allows those who don't speak the continent's language to learn it. Initially, the human languages of this world were numerous and varied. To facilitate communication, Gandalf, the forefather of wizards, invented a language scroll based on the most widely spoken language on the continent. Now, almost all humans know this universal language. I'll have someone fetch a language scroll in a moment, so your wife can learn our language," Krasil said.

"Well, if there's nothing else, let's try your food first, then rest and wait for the leaders of the three kingdoms before spreading the methods of ninja training," Issui said.

Krasil nodded and then led the way. The city lord's mansion was quite large. After turning around, Issui and the others arrived at the backyard, where there was a rather luxurious guest room. The surrounding gardens were very colorful, with various unknown flowers and plants arranged in a well-organized manner in every corner of the courtyard.

"This is the most luxurious mansion in Blue Mountain City. It was originally built to receive guests from elves and enemies. Now it is temporarily used as Your Majesty's residence. There is already wine and food prepared inside. I will have the language scroll brought up by a servant later." Krasil invited Issui and the others into the house, then apologized and withdrew.

"Ah, it smells pretty good! Come on, Bai, sit down quickly. Let's try the food of this world. These are all foods I've never seen before. I'm really looking forward to it." Issui gestured for Bai to sit next to him, and the two of them ate together.

Bai, on the other hand, was somewhat reserved, tasting the various dishes with a rather ladylike demeanor. Issui, however, didn't care about any of that and wolfed down her food. The most important thing about these dishes wasn't their aroma, but their rarity. Food from another world was still quite surprising and unusual.

Inside a palace in City of Radiance, the capital of the Radiance Kingdom.

A handsome middle-aged man, clad in silver-white armor and with long, flowing golden hair, sat atop a gilded throne shaped like an unidentified beast at the very top of the palace. He spoke, "I've heard that the Yis Legendary Is has brought news of the descent of a divine child. I wonder if this is accurate? Moreover, I've heard that this child is a descendant of Agustefelia, the God of Radiance and Wisdom, and has brought a new cultivation system that most people can practice. What is Your Majesty Celia's opinion?"

"Your Majesty, "Yis said quietly, "I believe it to be true. Is is the most cautious of my disciples, and his words should be true. I think you should inform the kings of the other two kingdoms and the Demigod to go to Blue Mountain City together. After all, this is our only hope. Over the years, most of your brothers, sisters, and children have been sent to the hands of magical beasts. It can be said that your family has made a huge contribution to the people of the entire kingdom. Now, if what that divine child said is true, then humanity's hope has arrived. If we secretly develop for a few years, we will be able to face the power of those magical beasts without fear. Even if it is just a glimmer of light, we must try Celia best to grasp it."

"Yes, for the survival of humanity, we can only sacrifice our own blood relatives to buy temporary peace. I can no longer endure this. Continuing like this is worse than fighting those monsters to the death. I will send word to the kings of the Thorn Flower Kingdom and the Azure Kingdom, as well as His Demigod. Humanity's hope has arrived. I hope the Divine Child will not let us down. This is our last hope..."

"Thump, thump, thump..."

"Please come in..."

"Hello, this is a language scroll that Lord Krasil asked me to deliver..." The waiter dared not look directly into Issui's eyes and respectfully presented the scroll to him. Although he very much wanted to see the face of this legendary divine child, he dared not offend the divine child's majesty and it was better to remain respectful.

"Hmm, thank you. How do I use this scroll?" Issui took the animal hide scroll from the waiter and asked gently.

"Ah, there's no need for any incantation. Just speak to the person you want to convey the words to in your heart." The waiter was somewhat flattered; the Divine Child didn't seem serious at all, but rather very gentle.

"Okay, I understand. You can go now. Also, please clear the food off the table; we're already full," Issui said.

"Yes, I'll have someone clean it up right away. You can continue with your work..." the waiter replied, still keeping his head down.

After washing up, Issui and Bai entered the dormitory. He made Bai stand in front of him, then tore open the scroll in his hand, and a beam of light shot into Bai's body.

"What an amazing thing! I learned a language all at once. Is this the language of this world? It feels like I've mastered it!" Bai exclaimed in surprise.

"Hmm, this world is more advanced in some ways than the ninja world. Let's go to sleep early. We've been through so much today, and I feel a lot of pressure." Issui lay sprawled on the bed without any regard for appearances.

"Really, aren't you going to take off your coat?" Her fair face flushed slightly. Was she going to have to sleep with him? What should she do?

"Alright, stop standing there. We're just sleeping today, nothing bad. After seeing such a miserable world, I have no desire to do 'that' with you." Issui took off her coat, threw it aside, and lay down on the bed to sleep.

Bai had no choice but to take off her outer clothes, but she kept her underwear tightly on. She lay down beside the Issui and fell asleep...

The next afternoon.

After lunch, Issui was invited to the front hall by Krasil, who said that the kings of the three kingdoms and the Demigod had arrived and asked Issui to go and meet them.

Following Krasil to the front hall, he found four men and two women already waiting for him.

"These are the three kings of the Radiance Kingdom, the Thorn Flower Kingdom, and the Azure Kingdom, and the Demigod who protects their kingdoms," Krasil whispered to Issui.

"I am Anuki Alexander, the eleventh king of the Radiance Kingdom," said the handsome middle-aged man, clad in silver-white armor and with long, flowing golden hair.

"I am Celia Fiore, the Demigod who protects the Radiance Kingdom, a tenth-tier wizard, proficient in wind and water elemental magic." The younger of the two women, a beautiful woman with long silver hair and blue eyes, stepped forward and said, "I am probably in my twenties."

"I am Kuro Malain, the tenth king of the Thorn Flower Kingdom," said the oldest of the four men, an old man clad in golden armor.

"I am Mark Slida, the guardian Demigod of the Thorn Flower Kingdom, a ninth-tier wizard, proficient in lightning elemental magic," the strongest of the men, with hard muscles and long, blood-red hair, declared loudly.
