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

On the Infinite Train, Tanjiro was walking in front carrying his sister on his back. This time, the three of them came to support the Flame Pillar Rengoku Kyojuro.

"Wow! So fast!" Inosuke leaned against the window with his eyes wide open and exclaimed in surprise.

Although it was now night and it was gradually getting dark outside with visibility not that high, he was still very excited.

"Stop messing around, you bastard!" Zenitsu rushed over and hugged him, pulling him while apologizing to the people sitting in the seats: "Sorry to bother you."

The three of them searched from carriage to carriage and soon saw the target.

Although he was not very familiar with the Flame Pillar, Tanjiro quickly confirmed his identity based on his exaggerated appearance and familiar smell.

"Delicious!" At this moment, Rengoku Kyojuro was no longer eating the snacks that Lei Dianying had brought out, but the lunch box he had bought when he got on the bus.

On the other table, the game was still going on, but a considerable number of chips were on Lei Dianying's side, and the other three people had almost lost all their money.

"Sorry, sorry to bother you." Tanjiro and Zenitsu came to Rengoku Kyojuro and greeted him with a somewhat nervous look.

The latter turned around and looked at the two of them while eating.

But before he could speak, Lei Dianying next door had already spoken, "Tanjiro, Zenitsu, Inosuke, Nezuko."

I didn't expect to meet the four people who were mentioned many times in the intelligence given by Shen Fei here.

"Do you know us?" Tanjiro turned his head and looked at the beautiful sister with some surprise.

Zenitsu next to him had a wandering look and wanted to turn his gaze over, but felt a little embarrassed.

"First time seeing you." Lei Dianying took out a few exam manuals and said, "I'm not good at dealing with your sister's problem, so I'll leave it to the people who will come later. But you can take a look at this first."

"Do you have a way to save Nezuko?!" Upon hearing this, Tanjiro became very excited.

"Calm down! Tanjiro." At this time, the Flame Pillar Rengoku Kyojuro could no longer focus entirely on the bento. He stretched out his hand and grabbed the other party who was a little out of control due to excitement.

Tanjiro reacted quickly and breathed a sigh of relief: "Sorry, I reacted too strongly."

"Sir, if you have a way to restore Nezuko to normal, please tell me! I will pay you enough!" He clasped his hands together and said to Lei Diandian sincerely.

"Your sister's body is filled with ghost energy, which is not difficult to handle, but the gap between us is too big, and your sister cannot withstand my power."

Lei Yingdian's expression was still very calm. "In a short time, other Teyvatian people will come, and your sister's body will be able to return to normal by then."

"Teyvat?" Tanjiro was a little confused.

So Kamisato Ayaka on the side spoke up and told the three people the story about the continent of Teyvat.

"This... this is impossible..." Zenitsu stuttered.

It would be hard for anyone to accept such outrageous information suddenly.

"After we investigate the situation here and wipe out all the ghosts, you will naturally believe it." Keqing looked at the three people with complicated expressions and continued, "Now the training license examination manual is here. If you want to gain more powerful power, study it carefully."

"If you don't want it, just throw it away."

After listening for so long, Tanjiro's head was already a little dizzy.

He took Zenitsu and Inosuke to sit next to Rengoku Kyojuro and asked, "What do you think, Mr. Rengoku?"

"To be honest, Tanjiro, I've just met them not long ago." Rengoku Kyojuro said to Tanjiro with a serious expression, and then explained to them what happened at the train maintenance center before.

"Let the lord and the others think about these things. No matter what, at least our current goal is the same as theirs, which is to annihilate the demons!"

Hearing the other party's words, Tanjiro nodded and didn't bother to dwell on it.

But he hoped from the bottom of his heart that what Lei Yingying had just said was true! This also meant that Nezuko would be able to return to normal soon!

Tanjiro and Rengoku Kyojuro talked about the reason why they appeared on the train. He originally wanted to ask each other about the Breathing of Flame and questions related to the Goddess of Fire Kagura, but now he no longer has the mind to do so.

He flipped through the practice license examination manual in his hand and read it carefully word by word.

"Coming." At this time, Rosalia, who was leaning against the window on the other side of the aisle, suddenly spoke.

There was a new ghost on the train. Judging from the aura emanating from it, it was much more powerful than the unknown ghost in the maintenance center.

Soon, Keqing and Kamisato Ayaka also felt the breath of the ghost, and it was very clear.

"Let's stop here for today." Seeing that everyone had noticed the existence of the ghost, Lei Dianying looked at his own terrible hand of cards, decisively put it down and started to clean up.

Up to now, Lei Dianying is the only winner in the game, while the other three have lost their chips to varying degrees.

In the last hand, Keqing and Kamisato Ayaka are both very good, but since Lei Dianying said he wanted to get down to business, they didn’t care, as they didn’t lack these Moras anyway.

Rosalia frowned. She didn't lose much and had a chance to make up for it in this round, but now it was obvious that she had no such chance.

Fortunately, Bartobas promised that there would be subsidies for business trips. Thinking of this, Rosalia gradually felt relieved.

"What's coming?" Tanjiro asked curiously, sticking his head out.

Keqing: "Damn it! The other party is standing at the front of this train."

what? !

Tanjiro, Zenitsu and Inosuke were shocked when they heard this. Inosuke even wanted to climb out of the car window to check, but was immediately stopped by Zenitsu.

"Your perception is really sharp!" Rengoku Kyojuro praised. He had just concentrated all his attention, but apart from the faint smell of ghosts on the train, he didn't feel anything else.

But this is how the train remains at the maintenance center, and it can be said that it has not changed at all now.

"There are many elemental energies in nature, so it's not difficult to sense abnormal auras." Keqing explained, "If it's a wind-type transcendent, the range of perception will be even greater."

"Really? We rely on a practice called breathing techniques to obtain various types of enhancements." Rengoku Kyojuro did not shy away from sharing the situation on his side. After all, it was not a secret.

"No! Are we discussing how to practice now?!" Zenitsu stared with his eyes wide open, a little upset, "Ghost! A ghost appeared on the train! And it can't be the murderer who caused the disappearance of the Infinite Train?!"
