The one with the crossbow, who saw Bella dodge, looks for one second like he might be considering it.  The other man screams a string of expletives (which Bella understands as easily as English) and turns to rush at Bella.  When he does, the other guy drops the spent crossbow, yanks out a sword of his own, and rushes up the hill beside his compatriot.

Bella has maybe three seconds to decide what to do about that.

Bella's gonna try to figure out the language bullshit later! She will charge at the men, sword drawn, going "AAAAAAH," and then dive between the two of them and somersault down the hill for the plate mail ladies at whom she will attempt to chant "healhealhealhealhealhealheal" in case that works.

This will require Bella to parry a couple of attempted swordstrikes in passing, but that's roughly as easy as thinking about where the sword needs to be in order to parry the strikes, so no problem.

Plate mail ladies:  Still dead so far as Bella can tell!

Her chanting does seem to have made the other combatants more wary of her, as they turn around to head back at Bella.  She might notice the former crossbow-holder's eyes briefly flickering to the plate mail ladies, as if to make sure that they are, in fact, still dead.

"Bluffing," says that one in a low voice.  "I think."

The two are approaching Bella more slowly now, the distance between them widening, with clear intent to come at her from two sides at once.

Oh good slow movement means more time to think. Bella makes sure she can see both of them and gives "resurrectresurrectresurrectresurrect" a shot, since apparently her opponents think this isn't completely ludicrous.

Bella's total failure to cast this epic-level spell seems to give heart to the two combatants.  They launch a sudden flurry of attacks at her, from two sides.

Bella seems to be parrying them all, for now.  It's probably not a very reassuring experience for her.  If Bella has ever played a video game long enough to get to the point where she can carry out maneuvers on reflex that she'd have no chance of doing with conscious thought, that's what she currently seems to be doing on a continuous basis, in the process of very quickly and repeatedly bashing away swords before they can pierce her.  Anyone observing the angles at which she's deflecting blows, such as the two combatants, will easily conclude that she has no actual  『Sword』 skills.

Would Bella like to try to kill or wound either of these two people?  They're sincerely trying to do that to her.

Well she sure seems to be out of alternatives doesn't she! Let's try to get one of these guys hamstrung, or unable to use his sword arm, whichever seems more accessible.

Blood.  Not Bella's blood.  Whether any of the screaming is Bella's screaming is up to her.  Her body won't be nauseated, but only she can determine how her mind feels about the bloody hand lying in the dirt before her, still clutching a longsword.  She meant for the sword to be in that place, edge out, cutting; she must have, because the sword goes where she means it to go.  Did Bella mean for there to be a bloody hand lying in the sand afterwards?

The man she's unhanded is trying to jam the hand into his own chest, maybe to stop the flow of blood, maybe to stop the pain.  The other man, the one who originally fired the crossbow bolt at her, has backed off from her a few steps while holding his sword in a defensive position.  "We'll take one quarter of the loot from the bodies, the carriage," he says in a harsh voice.  "Enough for my friend to get a 『Full Heal』.  You can have the rest of the loot, and the boy if you want him.  Deal?  You want more, you'll have to fight for it, and I doubt you can keep that 『Haste』 up much longer."

Bella was kind of expecting more resistance to actually slicing through a dude's wrist but she's not going to choose this moment to complain, let alone to assess whether her sword is the Subtle Knife. Why does she hear punctuation marks. Not the time. "Fine," she says, attempting to speak whatever this is but having no particular expectation that she can do it in that direction till she tries it.

In much the same way Bella now knows how to walk without tripping, she seems to know how to make her tongue say "Fine" in another language.

The guy with two hands takes a leather strap from the backpack of one corpse, and ties off his fellow's hand.  After that, the guy with one hand will keep to himself, gritting his teeth, occasionally emitting choked sounds, and staring at Bella with hate in his eyes.  He never takes his eyes off her, as the other guy loots pouches from the corpses on the ground, the ex-bandits and the two women in platemail.  Would Bella like to check his work, or check pouches herself, to see how much loot he's taking versus leaving for her?  She could also try to kill him while his hands are busy, if she's so minded.

Bella keeps an eye on what he's taking but she doesn't know these denominations so unless it all happens to be identical coins she's just going to watch him and not nitpick.

The guy is taking rather more than a quarter of the coins inside the pouches, though Bella has no way of knowing this without doing her own examinations.  Then again, he's leaving behind some valuable-looking platemail armor, to say nothing of the carriage and the horses required to transport it.

That guy is now approaching the door of the carriage, with a clear intent to open it, holding a wary sword and looking ready to dodge.  Does Bella care to say or do anything before this event plays out?

"You don't think you've had enough? Should I check?"

The guy stops and sends a harsh look at her.  "If there's any treasure in the carriage, I get a quarter, as agreed," he growls.  "You want to be the one to open it?  Be my guest, but be careful of the boy.  Guards like those, his family's rich enough for him to know magic."

"Uh-huh. Stand back."

As soon as the carriage door opens, a crossbow bolt will come out.  This one is from a higher-quality crossbow at nearly point-blank range.  It clips some of Bella's hair, and if the boy had guessed her location better, it might have wounded her before she could dodge far enough.

There is an angry teenage boy Bella's age here.  He drops the crossbow and begins to chant, in a way that feels like slightly different language bullshit to hear, "I offer you seven offerings of my mana, spirits of fire, to -"

"Cut that out! I am the only person here who doesn't want your stuff!"

Considering things from the boy's perspective, he has, of course, overheard the fight and the conversation that followed.  He now needs to perform a rapid mental calculation which includes the fact that his crossbow bolt missed, his spell takes a long time to cast, he isn't really much of a combatant, there's no way in hell he can recast this spell in time if he cancels it now, the strange girl might honestly mean to leave him alive and unenslaved, the strange girl isn't wearing an Adventurer's Guild plate, she agreed to divide up loot instead of fighting both bandits to the death -

The strange girl his age is dressed very peculiarly.

This, more than anything else, causes Haroun Pevers to cancel his spell.  "- do the unfulfillable clause.  Who are you and what are you planning to do?" he says, keeping his voice as calm as he can manage considering that Marussa and Aralin are DEAD.

"My name is" what if this is one of those stupid fantasy universes where telling people your name does spooky shit "not important. I wanted to open the door so that stabby guy didn't decide to stab you while casing the vehicle. He wants enough money to put his friend's hand back where it belongs and his friend has not decided to cast any aspersions on his honesty about it, do you know what that tends to run?"

It takes longer for Haroun to process this than he should.  His brain isn't in the best of shape.  If he thought that the girl herself was in a low-stress situation with lots of time to carefully compose her sentences, he might have blamed her for poor communication; as it is, he's a bit more understanding than that.

Haroun moves forward cautiously, to take a look out of the carriage door if she'll let him.  The meaning of her words is clearer when he sees the bandit nursing an arm-stump, and another surviving bandit who's reloading a crossbow.

Reattaching a severed hand... calls for a 『Full Heal』, right.  "Somewhere between... five and fifteen gold," Haroun says slowly.  Oh.  He hesitates before speaking again, but it's not like they can't just drag him out and search him and take what they want.  "If you tell him to count out whatever he's taken so far, I can try to fill in the rest up to ten gold," Haroun offers, just to see if the strange girl has cowed the bandits enough that they'll take that offer and go.

Is it just his imagination or is the weave on her shirt insanely regular?  He's seen spider-silk threads woven more finely than that, but not in such a ridiculously perfect triangular array.

"My eyes are up here. Stabby, count what you've got, please."

Stabby will count out a heap of twenty-seven silver coins in one hand, which he then shows to Bella.  A cynical mind would suspect that this was not, in fact, his entire gains.  Stabby also fails to say anything conveniently helpful for a recently isekaied protagonist such as "By the way, twenty-seven silver converts to the following amount of gold."

"Pretty sure you had more than that."

All right, the Haste-using girl isn't a complete idiot.  Stabby tries showing her fifty-eight silver coins and one gold piece, along with a carefully measured amount of resentment about his clever plans having been so utterly foiled.

"Dude. Work with me here before your buddy bleeds out."

Seventy-two silver and two gold?
