Tubbo only steals a little bit. He puts most of Jingyan’s stuff in a chest. 

Assuming he still has his pickaxe to do his promised clean up, he does not mind.

Yeah he still has his pickaxe. And his axe and his shovel. Otherwise Jingyan wouldn’t be able to do cleanup and then Tubbo would have to do it. 

Well so as the kleptomania is within sensible limits, he does not mind. He is not attached to his resources.

And now the pillars are coming down.

That’s probably a good attitude to have. “Right, I’m gonna head home now. I had fun!”

"Thank you for showing me redstone and pillar combat; it is much appreciated."

“Yeah, course! I fucking love redstone, dude, if you ever want to do more redstone I’ll probably be around. Or if you want to fight more.”

"I will keep that in mind."

Then Tubbo will head home!

And Jingyan has some arena building to catch up on.

There isn’t much time left before sunset, although he might not notice immediately, since he’s underground. He’ll probably get tired eventually, unless he’s the sort of person to work through the night on accident?

He would like to be the sort of person who would accidentally work through the night be accidental, but alas, he has mortal frailties, and ends up in bed by about midnight.

When he wakes up, Phil is cleaning up the very last blocks of wall. 

The! walls! are! gone!

FINALLY.

(He has basically no outward reaction other than a moment staring at the walls (and Philza) before heading back down to make the underground arena larger.)

A few days pass. The walls stay down. Ranboo and Tubbo start work on a guardian XP farm; Jingyan works on the arena; Tubbo spars a few more times with Jingyan. Jingyan might notice some weird red vines on the prime path, but they're cleared away soon enough. Ghostbur gives out blue dye to everyone, which he explains calms you and helps take away your sadness.

(Outside of L'Manberg: BadBoyHalo discovers a red egg. George, Quackity, and Karl stage an assassination attempt to gain independence for El Rapids. Sam starts work on a prison. Tommy dies repeatedly trying to make an ender chest.)

Jingyan is now the proud owner of some vaguely concerning blue dye. (Everything about Ghostbur is vaguely concerning at best.)

The amount of "TommyInnit was killed by (blank)" messages are also vaguely concerning, but seeing as death is fairly low stakes here, he is likely not... less fine than he would be if he was consistently staying alive.

He finishes the arena. At one point he makes it too large (? he is not entirely sure what exactly caused this problem, other than putting up a cobblestone wall fixing it) and it starts filling with giant green gelatinous creatures. A cube twice as tall as you are trying to incoporate you into into its mass is not unintimidating, especially when attacking it with a sword just splits it into smaller gelatinous creatures, But they do not kill him. It's always a good day when you do not get killed.

"Hey Jingyan! How's the arena coming along?"

"I would say it is done, now I have solved the mysterious cube situation."

"Nice, nice, that's always a good day, when mysterious cube situations have been solved. --Oh, hey Ghostbur!"

"Mr. President, hi! Can I compliment you on the wonderful city you've got going here today?"

"Awww, thank you, Wilbur! I mean, you did a lot of the work."

"I'm-- I remember I did a lot of it. But you kept it going! Do you two want to come see my sewer?"

"Yeah, sure." Glance at Jingyan?

As much as Ghostbur is deeply concerning, he does feel a bit protective of him. Enough to investigate sewers in case there is something worrying going on. (Hopefully its just more blue dye.) "Certainly."

It's not a concerning sewer at all! It seems quite nice, actually. A little cramped, but not bad, and it connects to a series of tunnels with water going through them (presumably these are the sewers). There's two rooms, one of which mostly stores books, the other of which mostly stores brewing stands and potions.

"This is my sewer! People have robbed me, I have been robbed. But that's just how this server is, you know? I'm just missing-- you can see some gaps in the barrels? Like, here I used to have about 12 potions of invisibility, now I just have one, and two swiftness potions." He leans forward and whispers conspiratorially: "I think it's probably Fundy."
