We agreed to be a tour guide, how did it become the law of nature?

The opponent was holding a short blade in each hand, with long and beautiful legs, and her figure floating in the air was very moving.

Boom!

The unknown ghost seemed to be hit by a huge force. He flew backwards instantly and hit the wall behind the waiting room hard.

"Cough! Cough!"

In the dust, the unknown ghost's eyes were wide open as if they were about to fall out, veins bulged on his twisted face, and he felt extremely terrified in his heart.

Who is this woman?! Run away, run away now! Otherwise you will die!

Just when the unknown ghost had this thought in his mind, he found that the fierce figure rushed over again. The other party took out a spear from somewhere in his hand, and the storm-like attack disintegrated his limbs in an instant.

Boom!

The spear easily pierced through the wall, and the unknown ghost opened his confused eyes and his body gradually became disintegrated.

There was a big hole in its head, and it was deader than dead.

So strong!

Rengoku Kyojuro was shocked. As he had just been holding a hostage in the hands of the demon, he did not dare to act rashly. He had to at least try it first.

However, the woman of unknown origin in front of him acted decisively, and her movements were sharp, clean and neat, with a special kind of beauty that Rengoku Kyojuro couldn't help but admire in his heart.

But what’s a little strange is that the other party doesn’t seem to be using breathing method.

But it is definitely not blood demon magic, Rengoku Kyojuro is very clear about this.

"Thank you very much! I am Rengoku Kyojuro, the Flame Pillar of the Demon Slayer Corps, but I have never seen you in the organization, nor have I heard of any other demon hunting organizations. Please identify yourself."

Rengoku Kyojuro first bowed to Lei Dian and others, then introduced himself loudly and asked.

Lei Yingdian said calmly: "Once upon a time, there was a glorious kingdom in heaven..."

It's still the same rhetoric, but now it's version 2.0. Since the last time in the Naruto world, many of the settings have been optimized, and separate annotations and explanations have been made for some profound and difficult to understand words.

But to sum it up in one sentence: this world is one of the back gardens of Teyvat, and the eyes of the gods noticed the abnormality here, so they came to solve it.

The amount of information was so overwhelming that Rengoku Kyojuro stood there in a daze, unable to believe it all.

It's not his fault. Humans have been fighting against demons for thousands of years. The latter have long lives and extremely strong recovery abilities, and the Demon Slayer Corps suffered extremely heavy casualties.

At the beginning, everyone tried to beg for mercy from the gods, but after trying various methods, there was still no change, so they gave up the idea.

Now, a few people suddenly appear and claim that they are messengers of God. Of course, Rengoku Kyojuro will not believe them directly.

"What you said is really too shocking. I will pass the detailed information to the lord. No matter what, our goals should be the same." Rengoku Kyojuro said.

Lei Dianying nodded slightly. She had not expected to convince the other party directly. "Your strength is too weak. I will teach you a new way of cultivation. This is the manual for the cultivation license examination. You can read it first."

Rengoku Kyojuro took the booklet handed over by the other party. There was not much content in it. It just gave a general introduction to the seven elemental abilities, as well as the restrictions that needed to be understood when applying for the training licenses corresponding to the seven different elemental abilities.

For example: elemental power should not be used in public places where a large number of ordinary people gather. When using wind elemental power to fly or glide on roads with speed limit signs, the speed should be controlled according to specific restrictions.

The vast majority of the content in this booklet is subject to restrictions similar to those mentioned above.

Rengoku Kyojuro flipped through it roughly. Although he could understand the text, the specific information was a little difficult to understand.

"You are a transcendent who originally existed in this world, so the process of applying for a training license is much faster than that of ordinary people. Now you just need to memorize this book, and it should be easy to pass the exam."

Lei Dianying sensed the other party's confusion, and while speaking, he gathered a ball of lightning elemental power in his hands.

"This is the element of lightning, which has extremely strong explosive and penetrating power. Of course, if you don't like it, you can also apply for a license to practice other elemental powers. Although the current rules of Teyvat do not limit a person to only apply for one elemental power practice license. But in principle, it is recommended that a person apply for one."

Very powerful! This shining ball of lightning in front of me is very powerful!

Rengoku Kyojuro stared at the peaceful thunder element in Lei Dianying's hand, and a feeling of trembling suddenly arose in his heart.

He was clearly aware that if the lightning in the opponent's hand fell on him, he would instantly turn into a ball of ashes.

No! Perhaps just a portion of the other party's energy would be enough to do it easily!

"I understand! I will study hard!" Rengoku Kyojuro had more trust in the existence of Teyvat, but he still remained somewhat vigilant.

Although no traces of ghosts have been found on the other party so far, when he exerts his power, it does not feel like blood ghost magic at all, but rather an unprecedented energy.

However, Rengoku Kyojuro still couldn't be completely sure that the other party was on the human side.

What if... the demons develop a new blood demon technique and completely hide it from the Demon Slayer Corps, the situation will be very bad!

Rengoku Kyojuro was unable to think about so many things. What he had to do now was to record all his experiences in detail and then have them passed back by crows.

To be on the safe side, I will stay with the messenger of Teyvat for a few days until the lord brings back the message.

Rengoku Kyojuro thought to himself that in this way, he could also verify from all aspects whether the information the other party said was true.

Even if there are any problems, he will be the only one to pay the price!

Lei Yingdian received an invitation from Rengoku Kyojuro to investigate the Infinite Train together, and he immediately accepted it.

Anyway, all demons must be destroyed. In addition, a new training system and sword-forging skills must be taught here, so let's start with the Flame Pillar.

……

In the quiet dusk, the Infinite Train, which had been inspected, set off again. This time, not only the Flame Pillar Rengoku Kyojuro boarded the train, but also Lei Dianying, Keqing, Kamisato Ayaka, and Rosaria who came from the continent of Teyvat.

There was always a faint ghostly aura in the train, but until the train started, Lei Dianying did not sense the presence of ghosts.

But this is just the beginning, and perhaps not every train will have an accident.

With nothing to do, Lei Dianying took out some snacks and mahjong and invited Keqing and others to spend time together.

"Delicious!" Rengoku Kyojuro on the other side of the aisle was also given some snacks. After tasting them, he was immediately amazed.
