In Douluo Continent, my summoning of Naxi Da was exposed by the heavens.

Once they arrived at the exact location, Sandonne became noticeably anxious, which was evident in his voice.

"We're here. Move aside a bit, I'm going to activate the waterproof mechanism."

"There's actually such a mechanism."

"At that time, Alain, like René, had long anticipated that the water level in Fontaine would rise."

Using his familiar mechanical principles, he constructed some simple waterproofing measures around his secluded dwelling.

I originally said there was no need for this, and I would naturally move after the flood.

But now it seems he had predicted it all.

As Sandonne spoke, a look of sadness crossed his face, but he quickly recovered.

"Alright, the annoying mud and sand have been cleared away."

The travelers continued forward, where there were several more mechanisms. After operating them in sequence, the door to the secluded hut finally opened.

Once you actually go inside, it's a place that's like a paradise on earth.

There is a small house here, and in front of the house are several flower beds, which are still full of flowers.

"Wow! Is this where you used to live? It's quite beautiful! There's even a garden."

"Yes, when I was still living here, I was in charge of taking care of the potted plants and garden. I didn't expect that after so long, you would still be growing so well."

However, some people raised objections at this point.

Ning Rongrong once planted a garden, but after losing interest, it was abandoned and became overgrown with weeds within a few months, with not a single flower left.

"Senior Leira, does Teyvat have the technology to keep an untended garden blooming with flowers forever?"

"Such technology should exist, but I don't know much about it."

But since Alan Giyodan is called the Master of the Machines, he must have a very high level of skill.

It seems quite reasonable to find a garden in his secluded dwelling that blooms with flowers without needing any care.

"If we had such technology, those nobles would probably love it."

"Tending a garden in Douluo Continent shouldn't be too difficult, right? Just invite a plant-type Soul Master and it can be done easily."

"Yes, but many Soul Masters are too proud to use their Martial Soul to do this kind of thing."

"This viewpoint definitely needs to be improved. Martial Souls should be properly developed to explore different application scenarios."

Limiting the use of martial spirits to only combat is a waste of their potential.

Back on the celestial screen, Sandone walks toward the cottage, telling the traveler, Paimon, about their past.

"When the weather is clear, I will push Alan's wheelchair out for a walk, and then take Pronia out for a stroll."

Thinking back, of the three of us, I was the only one who was relatively agile. Pronia would often get stuck halfway through, and I would have to rescue him.

"That sounds like a very pleasant memory."

"Peaceful, yet joyful. Repetitive, yet heartwarming, as if living in a world where time does not exist."

Of course, that's just wishful thinking; death still awaits each and every one of us at the end.

Okay, let's not just stand outside anymore, let's go inside and talk.

Stepping into his old cottage, Sandonne was filled with emotion.

"Sure enough, this place is exactly the same as when I left, nothing has changed."

"Oh, right, Sandone, there's something I need to return to you..."

"Huh? What is it?"

"Your notes..."

"Oh! How come you have...?"

Halfway through his sentence, Sandonne remembered something.

"Ah! It was Arecino who gave it to you, wasn't it? You... all saw it?"

Haha... a lot of this content was written a long time ago, even here, to be precise, on this table.

Hmph, since you've already seen it, you can keep it for me. I'll use a new notebook if I want to take notes.

If you'd like, feel free to wander around. I'll look for the legacy Alan mentioned nearby.

Be careful when you take things; it's not that I don't want you to touch them, but I'm afraid the dust that's accumulated here could choke you.

The traveler and Paimon looked around the cabin.

The traveler first noticed a small toy on the table, which seemed to be related to mathematics.

The traveler tried it out and it seemed quite difficult.

On the Douluo Continent side, Kavi said to Elheisen, "Look at that toy, can you solve it?"

"It's a classic math game where you rearrange the gears in the fewest possible moves."

It's not overly complicated, but of course, pushing it to its limits isn't easy.

"Would you like me to make one for you so you can try it out?"

"No need. If you have nothing to do, go and draw your blueprints."

On the sky, seeing the traveler playing with the little toy, Sandonne also came over.

"Hey, isn't this something I played with when I was little? When I say 'little', I mean the first few months after I was born."

At first, I played with Alan, but I learned very quickly, and gradually he couldn't beat me at chess anymore. So later I played with Pronia.

"Hmm... this is clearly not a game I'm good at."

"Hmph, these are all logic and math puzzles, I'm a pro at that! It brings back so many memories, wanna play a couple of rounds?"

"OK!"

However, travelers still don't quite enjoy it.

"You seem to have been thinking about this for a long time. Do you need any help? It should be like this here, and then like this."

Sandonne's hands moved very quickly, and he quickly put the gears back in place.

"So, do you like this game?"

"It's a bit difficult."

"Yes, indeed, not everyone will like these mathematical puzzles. Thinking about it that way, my childhood was somewhat special."

The traveler and Paimon then saw some manuscripts on the table.

"These are some of Alan's manuscripts from his later years, or rather, his scribbles."

There were also some minor details that I was too lazy to deal with when I left, so I just left them unattended.

Then, the traveler and Paimon found another photograph in the corner of the room.

"Hmm, the person in the photo looks so familiar."

"Oh! This photo was taken when Alan and René were still at the Fontaine Academy. They had a good relationship back then."

In his later years, Alan would often sit quietly in front of the fireplace, holding this photograph. His expression was somewhere between nostalgia and guilt.

He said he sometimes regrets not helping his friends when they needed it most, even if it was just stopping them.

Finally, the traveler and Paimon saw a somewhat dilapidated workbench.

"This was Alan's worktable, which later became my worktable. Pronia and I were all born on this worktable."

When Alan was still able to get out of bed and walk, he would teach me a lot about mechanics here. I would sit here and listen quietly, occasionally asking questions.

Later, he couldn't get up anymore, and that became the place where I wrongly eliminated Pronia.
