Then, Eero realized clean fuel in a small cylinder, then plugged the cylinder with a small noiseless generator.
This generator is a high-tech product; it's just the size of a small box, 1 ft in size. It looks small, but it produces 5 KVA electricity with minimum gas consumption. A cylinder can easily last for a few days, and it also charges all the carbon batteries through UPS in a few hours. Then, those batteries last for a few days. Carbon batteries are more efficient and long-lasting than those lithium batteries; a small four-inch carbon battery lasts 40Ah.
"Aye," a sound spread through the apartment.
Eero startled, then smiled and appeared beside the door of the room, looking at little Ada waving her little hands, sitting on the carpet, playing with glittering toys, laughing, and babbling.
"Well, I hope she fell asleep so I can go to the metropolis," Eero muttered thoughtfully and started playing with her. He decided to visit the metropolis city, in order to buy some useful stuff and analyze the technology in this world fully.
After a while Ada fell asleep, he left the apartment, closed the door, and upon walking through the stairs toward the lower floor, he halted, turned, and glanced at the few figures standing around on the 6th floor, with a few standing in the lower stairs, looking at him in surprise then smiling wickedly.
"Kid, we were waiting for you. We heard something crazy about you. You stay for weeks on one floor, don't go searching for food like others, renovated the floor, guess what, we are surprised to find that everything they say about you is true," one of the men standing said.
Eero glanced at the bag on the ground beside him with a hammer and other hardware tools. Looking at their masked faces, also tattoos on their bodies, 'So they are the local gang residing near this area. They were probably going to break into my apartment.' Eero thought to himself.
"Well, I don't know if it's your fate or luck, but you're all going to die," Eero said calmly.
Instantly, all gangsters and a beggar among them froze, then laughter spread through the whole building.
"Ha ha ha!" A few gangsters grabbed their stomachs and sat down on the ground.
"He he he he he."
"Hahahahaha"
Eero speechlessly glanced at everyone laughing loudly, shook his head, sighed, 'Well, they are lucky at least they laugh before death.'
He raised his arms, mini crossbows appeared on both wrists.
Tusk!!!
Arrows ejected shot around instantly, piercing the heads of a few gangsters around, suddenly the arrow burst blood and brain splashing around.
Blop!!!
Thud! Headless Corpses fell to the ground.
"Huh," silence spread around. The other gangsters around were startled took a deep breath in horror, looking at the fallen companions around, who were just laughing with them, arrows bursting in their heads, rendering the ground below red.
"Ahhhh!" one of the gangsters shouted in horror, grabbing the arrow embedded in his chest.
Blop!!!
His chest burst, whole internal organs scattered around.
Others were startled pale, instantly a few pulled out their guns, aiming at Eero's direction. The next second, they were surprised, looking at the empty stairs
"Where did he go?" One of the gangster shouted with trembling Palm's and body.
Chilly sweat flowing through everyone face and forehead, they all felt goosebumps.
Instantly arrow from unknown direction pierced through few more heads,
Swoosh! Blop!!!
Thud!
Few corpses with guns fell to the ground; the beggar who brought the gangsters ran and sat in a corner in horror and fear.
'I can't let them fire or I will have to deal with the security department; the trouble may escalate,' Eero thought, standing behind the pillar. Instantly, new arrows materialized inside the crossbow, and the mechanism inside moved. Few dagger's appeared in his hands, grabbing them tightly, his ear's moved hearing the footsteps and analyzing their location through sounds.
It's the similar to bat 🦇 echo skill. He learned it in the previous dimension while hunting and locating those invisible monster's, it came handy now.
A chill rushed through everyone's spine, feeling extreme tension, but they couldn't track and locate Eero.
After a while,
Eero stood in one of the rooms, raised his hand, a dagger appeared. He locked his wrist, shot it at the direction of a gangster outside through the window, then rolled out of the door, shot another gangster using the crossbow.
Corpses fell one by one as if scattering leaves.
After a while, Eero killed the last gangster by piercing his eye and messing his brain inside. He stood up panting feeling extremely exhausted, after taking deep breaths, glanced at the corner, he can hear someone breathing.
He walked and appeared beside the beggar who brought those gangsters; he was sitting grabbing his mouth in a corner.
Looking at bloody Eero in front of him and his dark expressionless gaze, his heart gripped in fear, he hadn't known before.
"It was you who informed them, I know you. You were the one paying attention to us, When I brought my sister here; a few months ago." Eero asked expressionlessly, looking at him.
"Monster! Monster, you are a monster. Leave me alone!" The beggar shouted, grabbing his head in horror and didn't dare to raise his head.
Eero aimed at him, then shot the arrow through his head, blop blood and brain splattered around in the corner.
Eero sighed shook his head, glanced at the small crossbows on his arms. 'These Tang clan crossbows are really amazing and handy; I saw Tang San using them in the Douluo Dalu anime,' he thought to himself. He tried to realize items from those other dimensions before and didn't expect it to be successful.
Shook his arms, both crossbows disappeared from his wrists. Then he raised his hand, a corpse dissolving solution appeared in his hand. He opened the cork and dropped it on every corpse one by one; they dissolved instantly and turned into ashes along with clothes.
Leaving blood marks around, he then used spray to let the blood marks disappear, then removing all other evidence around.
After erasing all mark's restoring everything back, he returned to his apartment. 'It seems I have to deal with more gangsters, or maybe those police officers may visit next time because of the missing gang. Well, it doesn't matter; no one pays attention to criminal officers like them,' Eero thought to himself, standing beside the window in his apartment.
