The so-called return stone is a newly extracted space item that Chen Yan previously extracted. The keyword setting for this also cost him 100,000 points, so the rarity of the word 'space' is obvious.

However, he was lucky enough to pull it out in the end, but he didn't expect it to be a strange stone. He originally thought it might be some kind of Flying Thunder God, Teigu Shangri-La, etc., so he was a little disappointed.

But after reading the introduction, I finally breathed a sigh of relief that this opportunity to draw was not in vain.

And this strange prop is really inexplicably suitable for his current situation.

Items: Heart of Return

Effect 1: A certain number of return stones can be differentiated every month

Effect 2: Functional buildings with unique characteristics of this force can be set as the return point.

Effect 3: The heart of returning to the city can be used as a returning stone, no countdown, cooling time: one hour

Return Stone: Choose a return point, read it for 3 seconds, and move yourself to any location in the return building.

Well, there are quite a few restrictions, but to some extent it is very maneuverable. Overall, it is very suitable for the current Vongola.

Chen Yan, who knows how to be content, is naturally very satisfied.

However, when it comes to this limitation, this desire to return is indeed a bit tricky.

The most critical one is the second point of the explanation, which states that setting a return point requires a ‘functional building with exclusive characteristics’.

The most confusing part is this 'exclusive feature'. Originally, he wanted to set up return points within Vongola's sphere of influence, which would have a huge effect in terms of convenience and tactics.

However, in the end, it showed 'cannot be set', which made him really depressed.

Finally, after Yu’s explanation, it turns out that this ‘functional building with exclusive characteristics’ not only belongs to the forces you control, but also has functional characteristics.

In fact, it is similar to buildings with special attributes in some farming games, such as "natural disaster resistance 1" and "increased talent attraction rate", which are somewhat abstract attributes.

But the problem is that One Piece is not a game world, so how can a building have such attributes? As a result, Yu said that this is just a prop produced by a game.

This really put Chen Yan in a difficult situation. He opened a good item, but ended up not being able to use it. As expected, the previous draws were all blessed by the God of Luck, or the karma was too deep.

Do we need to learn from the world of Xianxia and treat buildings as magic weapons to refine weapons?

He will not.

Let the building eat a devil fruit? This seems to be somewhat feasible.

It's just that he doesn't have this kind of technology. If it's okay for animals and other creatures, this house is just an inorganic thing with no mouth.

I have heard that the Navy's scientific force is researching this technology, but water from afar cannot quench the thirst for nearness, and they are not willing to hand over such precious technology to others, and it is not one of their own.

"In fact, you can use the additional function to set your fire as a 'building holding item', then the item and the building will be connected."

You didn't intend to trouble Chen Yan and directly gave him the key reminder.

When Chen Yan heard this, he instantly understood what Yu meant. His fire did have characteristics. As long as it was set as she said, the building he held would also have the characteristics of an item.

This reminded him of those cities in the end of the world. He had also given fire to those cities, so that they could frighten the beasts that were eroded by the blood poison and became unconscious.

Except for the superior species, others generally dare not invade the city, so they can preserve the pure land of human existence and continue the inheritance of civilization.
