The Forge Master in the Blade of Demon Slayer

This trip was much faster than the first time, and the two of them had already arrived at their destination before night fell.

Light the torch and go in, unimpeded to the front door.

Ichiro was terrified, and the hairs all over his body were about to stand up: "Teacher! Is... is someone here?"

The door was open when they left, but now when they came back, the door was closed again.

Tiezhi Sosuke did not answer, but observed the footprints on the ground.

Although he is not a hidden person and has no relevant skills and unique skills, the footprints on the ground are very clear. There are only two types, belonging to two people, and there is no footprint of a third person.

"No one has ever been here." Tie Zhi Cangsuke said with certainty: "Here, there are only traces of the two of us going in and out."

"Then this door?"

Ichiro's face turned pale.

Tiezhi Cangsuke was a little dumbfounded: "I found out that you are indeed less courageous than your brother. No one came, it doesn't mean that the door will not be closed. When you opened the door before, you also heard the gears running inside. The sound, this shows that there is a mature organ structure inside. Because of the external force, the door is opened. But this kind of opening may be just a delay device, after a certain period of time, it will close by itself. "

"Delay device?" Ichiro wondered.

Tie Zhicangsuke thought for a while and said: "It's very simple, you can understand it, hang a stone with a rope, pull the stone up, tie the rope to a tree, and then put a torch or candle under the rope .This is the principle of a simple delay device..."

"When the torch burns the rope, the stone will fall down, and the delay is the burning process." Ichiro instantly understood what Tetsuno Sosuke meant: "The teacher said that there is a torch hidden in this door?"

Tie Zhi Cangjie's face darkened: "Don't mess around."

Ichiro suddenly laughed, of course it was just a joke.

After Tetsuno Sosuke's explanation, Ichiro quickly understood what he meant by inference.

Of course there is no torch in this door, but who said that only torches can be used as a delay device?

Weights, objects, etc... Everything can be the key to a time-lapse device if it is arranged cleverly and just right.

There must be a device in this door, which was triggered after a relatively long time, and then the door was closed.

After figuring it out, I felt that there was nothing to be afraid of, and Ichiro immediately started preparing the white cloth.

This door is very tall, very wide.

The two decided to rub the outside content first, and then rub the inside. Judging from the size of the door, these two rolls of fabric must be enough.

Tie Zhi Cangsuke grabbed the cloth head, and the person under his feet rushed out, reached the top of the cave, and poked Yang Yan into the gap between the gate and the cave roof to temporarily stabilize his body.

Then he arranged the white cloth and fixed it, and Ichiro below started to cut the white cloth along the bottom of the gate.

Tiezhi Cansuke got down again, grabbed the cloth and went up, repeating what he had just done.

After a while, the two covered the entire door with a white cloth.

Ichiro brought water and ink, and looked at Tetsuno Sosuke.

Tiezhi Cansuke said: "I'm in charge of the top, and you are in charge of the bottom. After this door is over, open the door and print the contents inside."

Chapter 410 The Sixth Story

Master and apprentice are busy!

Tossing up and down, hanging cloth is easy, but rubbing is troublesome, mainly because the door is too big.

If someone helped, it would be much easier to set up a shelf or something, but no one came to help.

In the process of Tie Zhicangjie's busy work, he regretted more than once that he should let the hidden people do this job... But it's useless to say it now, there is no turning back arrow after opening the bow, so he can't just run away in a hurry ?

Turning around, I asked Yoya Shiki, the obstetrician, to find someone to get the other half back, and when he asked why he got half, how should I answer?

I still have to face it!

Gritting his teeth in the end, he finally rubbed the front and back of the door. The master and apprentice have lived in the cave for two days.

Occasionally take a rest and eat something, and find a place to sleep when I am sleepy. I am too tired, so I tidy up the white cloth with dried ink and look at the content...

In this way, when the work is completed, both people feel like they have been reborn.

"Teacher, let me fight ghosts next time. I found that this job is more tiring than that."

Ichiro said to Tetsuno Sosuke with blank eyes.

Tetsuno Sosuke was looking at the white cloth, frowning while watching, and waved his hand to tell Ichiro not to speak: "Bring the box."

"Huh?" Ichiro was stunned for a moment, and immediately sent the box to Tetsuno Sosuke.

Tetsuno Sosuke held the box and said to Ichiro: "The front and back of this door seem to be two stories... The first story is a journey to study alone. He first went to learn characters, and then went to learn Counting, and then changing to temperament...the first two are very common, but only the temperament is even given the score."

Ichiro cheered up and hurried over to take a look.

Sure enough, I saw a picture somewhere on the white cloth, and there were two people on the picture.

One person sat there playing the piano, while the other sat with bowed head, listening respectfully, and there was also a piano in front of him, but on the piano case, there was an open book, and there was no other book on it. There is nothing in it, but if you look carefully, you can see the score.

This is a very inconspicuous little detail on the whole door. Even if you don’t take it up to you, even if you know that there is such a place on the door, it will be difficult for you to find it in a while. where the sheet music is located.

Tetsuno Sosuke held the box in front of his eyes, and Ichiro looked expectant.

It's time for the answer to be revealed!

Is it the final password?
