Here's your revised text with grammar and spelling fixes, along with suggestions for clarity:
"After a few hours into the night, they were exhausted.
Their battle had raged from the floor to the bed, surprisingly to the ceiling, back to the bed, and once more to the floor.
Almost everything in the room was broken or damaged.
Even the floor had deep cracks.
Lenny lay on his back, breathing heavily, while Gar lay on his chest.
"Not bad! Not bad!! You've gotten stronger," she complimented.
"But it will be a while before you're strong enough to marry me!"
"Marry you?" Lenny's eyes twitched a bit.
At the same time, Vine took over, rising up from his body. "Marry him!? Are you insane, Gar!? We just ran away from one marriage, and just because I let you be with him, you want to marry him?"
"Well, I think that's the only feasible solution! I mean, with what just happened, I might already be pregnant." Gar had glee on her face as she rubbed her stomach affectionately.
"Huh!? I'd rather stab myself to death than get pregnant for this trash," Vine retorted, grabbing Gar by the hair and pulling it.
"But I want to marry him!" Gar struggled with Vine.
Gar also grabbed Vine by the hair, pulling it. "But he is a better choice than that Blood demon. At least I love this one."
"But I don't!" Vine groaned in anger.
"But it's my body. I can marry who I want."
Follow on NovᴇlEnglish.nᴇt"Well, it's my body too. Just because I allowed you to be with him twice, you think I'm okay with it?"
"What do you mean? You enjoyed it as much as I did. Just let us marry him. You could even help me convince father."
Meanwhile, as the two quarreled with one another, Lenny just sat there naked, watching one person fight with herself, constantly pulling her own hair and begging herself to stop.
Lenny couldn't help but raise a brow at this.
Here he thought maturity came with strength. Apparently, he was wrong.
At this moment, he couldn't help but look at the Satan System mission list.
There was a bright red tag that listed 'mission failed.'
This was expected; after all, he wasn't able to defeat the giant octopus.
Instead, that glory went to Riff.
However, what really caught his attention was the punishment tag that appeared.
<Host accepted a mission from the Fates>
<Failure to fulfill mission results in a penalty>
<Penalty: Magic Points locked for thirty days>
Instant shock registered on his face.
Never in his life had he received such a penalty.
The stronger Lenny became, the more he understood the importance of power.
The elimination of Magic Points alone was nearly half of his combat strength gone.
Without Magic points, he couldn't use White Flames. This also meant that he couldn't use skills like Fireball that deal a wide range of damage.
And this was to happen for an entire month.
Lenny couldn't help but regret ever taking that mission.
But the reward was an increase of 500 points across all his stats.
It was only natural that he couldn't resist it.
From the look of things, he could tell that he had somehow made it into the city of Milk and Honey.
But this was no assurance to him.
After all, these were the Wastelands.
Peace was an illusion in these parts, a fantasy people loved to dream about.
Especially with the kind of enemies he had, he wouldn't be surprised if Cuban came for him in this place.
Lady Vinegar had managed to find him. He didn't think that Cuban wasn't capable of that too.
Instinctively, the first thing that came to his mind was to leave this place and go hide in silence somewhere.
He was sure that if he managed to hide in a hole somewhere, he would be better able to preserve his life.
Of course, there was also the option of hiding under Vinegar.
She was obviously far stronger than Cuban, but Lenny couldn't help but sigh at this thought.
He didn't consider himself a coward and wouldn't act like one.
Although a part of him was indeed shameless enough to do it.
However, one look at Lady Vinegar and it was easy to tell that she had a lot going on for her.
Having two personalities was not easy at all.
Follow on Novᴇl-Onlinᴇ.cᴏmAnd Lenny could tell that only one of those personalities liked him.
The reason for it, he didn't know, but he couldn't help but imagine a day when the personality that didn't like him would decide to just extinguish his existence.
His brows twitched at the thought.
Lenny couldn't help but facepalm.
He really couldn't understand why he was so unlucky with women.
In one way or the other, they were just crazy or abnormal.
He was starting to think maybe the heavens cursed him or something.
While his mind calculated his next step, he suddenly remembered the image of that red eye and the name...
"Victor!"
Yes! He remembered it now. This was the reason why he came to this city.
To find someone who could help him get to the Wandering city called Judas so that he could see that Angel that Glenn had told him about.
And according to the vision he had gotten from the Primordial beast, he needed to find Victor.
He immediately stood to his feet.
He still had some bruises from his fight with the Giant Octopus, but most of it had already healed.
Some new ones were also there from his encounter with Gar, but it was not something that he couldn't handle.
He stood up, waving his hands, and a change of clothes appeared.
While Lady Vinegar bickered with herself, he dressed up.
However, Gar caught sight of this.
"Hey, where are you going?"
"To find a person named Victor," he replied without turning back.
"I'm right here!"
(Author's note: what do you think will happen now that things have progressed this way?)
