Mission in another world with my transformed best friend

"Why are they all just random books like those in Earth's 'library'? They're somewhat useful, but are there any high-quality resources that would instantly make me a force to be reckoned with in this other world, giving me a cheat code to dominate?"

Suddenly, Wang Kai felt a thin manual under his feet. He immediately picked it up and saw the title, "Adventurer's Guide." His eyes lit up, as if he had seen the "Nine Yang Divine Skill."

Gently brushing away the grime from the manual, Wang Kai carefully opened the first page. Because it was too dark around him and the moonlight was obscured by dark clouds, he couldn't see the contents clearly... He then remembered that there was an oil lamp in the cellar earlier.

"Martha, are you dressed? I'm coming down..."

I knocked on the cellar door, but there was no response.

In his haste, Wang Kai disregarded everything else, gently opened a small opening, peeked inside, smiled, and went down.

It turned out that Martha was leaning against Zhang Lan like a younger sister. From their sleeping expressions, it was clear that they had experienced a terrible day and were exhausted to the extreme.

Although Wang Kai was also feeling a bit tired, he knew he had to get on with reading the "Secret Manual" as soon as possible. So he took down the oil lamp, ran to the other side of the cellar, and lay down on the wooden planks that had been laid out as a makeshift bed to slowly begin reading...

The manual is thin, only covering the adventurer's profession and some attribute and skill introductions, as well as some precautions for adventures, etc.

Wang Kai read it word by word as if it were a priceless treasure, afraid of missing a single punctuation mark.

As a wealth of information and details about the other world flooded his mind, the corners of his mouth curved upwards to their maximum extent, as if he had returned to the days when he was a child, secretly reading game magazines under the covers...

"Hey, why are you sitting on the floor with your legs stretched out like that? Pass me the oil lamp, I can't see where I'm going..."

The sound of Zhang Lan's groggy voice after waking up came from the side, but Wang Kai, whose ears were completely deaf, remained in the same position, his hands still flipping through the manual that he could almost recite every word by heart.

Zhang Lan wasn't in the mood to waste words with him. She scratched the back of her head, walked over to Wang Kai, and kicked him.

"Good dog, don't block my way, move your leg, I need to pass..."

"Oh, do as you please..."

Coming to his senses, Wang Kai simply moved his foot slightly to make way for someone.

Zhang Lan was a little curious. What was this guy so engrossed in reading in the middle of the night? So she leaned closer to take a look, glanced at it a few times, and then sighed and said.

"Seeing you so focused, I thought you were preparing for graduate school entrance exams. What's the point of looking at this? Will it help you become a powerful figure in this world and do whatever you want?"

"While it may not reach the level you described, at least I've found a direction for initial development..."

"Leveling up by killing monsters and getting equipment?! That's way too lowbrow. Is that all a hardcore gamer like you can achieve? That's too one-sided..."

"What? Isn't this what players do in RPG games? And I've been searching all over here and this is the only useful manual I've found. The rest seem useless; they're all just introductions to local features and some historical texts."

"Huh!?" Zhang Lan's sleepy eyes widened instantly. "Where?"

"It's right next to me, I'm going to use it as a pillow later..."

"Why didn't you say so earlier? I was just taking a piss when I came..."

Zhang Lan cursed and immediately ran upstairs, while Wang Kai added a sentence from inside the cellar.

"By the way, just a heads-up, you'd better not pee standing up right now, or you'll wet your pants!"

"Fakyu!"

As a series of chaotic footsteps disappeared from the cellar entrance and then reappeared, Zhang Lan plopped down on the floor without pausing. Since there was only one oil lamp, she had to lean against Wang Kai for light and began to read earnestly...

As night deepened and the temperature gradually dropped, nothing could dampen the burning thirst for knowledge of the two young people who looked like they were taking the postgraduate entrance exam the next day. But no one, not even the gods, could have imagined that it was on this night of "studying diligently by candlelight" that two legendary figures were born, figures who would change the future of the entire continent...

……

After an unknown amount of time, the dazzling sunlight pierced through the cracks in the wooden floorboards and seeped into the basement, heralding the arrival of the first day after the "doomsday village." But apart from the change in light, everything was so quiet.

In the past, the Adventurers' Guild would have been bustling with activity. Whether it was the guild's receptionists or buyers, many passing adventurers would stop here to accept quests or inquire about various information for their adventures...

"Big brother, I'm sorry to wake you up, but it's time to get up now..."

As Martha seemed to whisper softly in his ear, Wang Kai opened his eyes with a soft "hmm," only to find it still pitch black. He then gave a wry smile, removed the "Adventurer's Guide" from his face, and after a few seconds of adjustment to the not-too-intense light, he could see Martha leaning over the edge of the makeshift bed, smiling at him...

Good morning, Martha.

"Hmm, good morning. Perhaps you were too tired last night and fell asleep without any covers, so I brought you blankets. I didn't disturb you after you woke up today, but now... it's almost noon, so I made some food and that's why I came to wake you up..."

"Ah... I'm sorry, I'll get up right away. Hey, Martha, why is your face so red? Do you have a fever?"

"No...no, it's just..."

Martha's gaze was somewhat evasive, but her eyes kept glancing at Wang Kai's lower body.

Wang Kai was also a little confused, his gaze falling downwards. Huh? Why was there a blanket covering him? The blanket itself wasn't strange, but what was odd was the bulge underneath it?

"Could this be a man's 'normal morning response'? If so, this size is a bit beyond human limits. I saw it when I peed yesterday, and it was just a normal size. Even so, why doesn't it feel swollen? Instead, I feel a stuffy, oppressive sensation, like something heavy is pressing down on me..."

A few seconds later, Wang Kai recalled what happened last night, immediately grabbed the blanket and pulled it off. He saw Zhang Lan curled up on his chest like a kitten, with her hands hanging down to her sides and holding a book.

When Wang Kai lifted the blanket, Masha covered her face and took a step back. But when she saw through her fingers that the scene was different from what she had guessed, she breathed a sigh of relief, and the blush on her face gradually faded.

"I've prepared some hot water for washing up, big brother and sister, please come up quickly..."

As Masha left, Wang Kai's gaze gradually fell on Zhang Lan. Good heavens! Last night, he was so focused on reading the "cheat manual" that he completely forgot when the two of them fell asleep and when Zhang Lan used him as a bed.

Moreover, we couldn't see her clothes clearly at that time. Wasn't it just a tight-fitting top and leggings? This kind of bedtime outfit for girls, which is not usually considered "perks," seemed so different because of the two people's posture.

In particular, the feeling of those two small but soft lumps against his abdomen told Wang Kai both a rational and emotional truth.

Sentimental—Last night I slept in the same bed with a beautiful blonde girl.

Rationality—I spent the whole night being held and cuddled by my best buddy, an older man.

As the blanket was pulled away, the cold air made Zhang Lan shiver a few times. Her outstretched hands slowly wrapped around Wang Kai's waist and hugged him tightly, while she also lifted one leg up and pressed it against his thigh...

The whole scene is exactly like a girl hugging her favorite fluffy plush toy when she falls asleep...

The limp feeling in his body became more and more obvious, and the girl's sweat and heat began to surround him, causing Wang Kai's blood pressure to slowly rise. A portion of his blood obediently flowed towards his "good brothers." He knew that if he waited another minute, it might cause an irreparable misunderstanding...

However, Wang Kai still detected a faint odor; it was...it smelled like urine.

He immediately understood, reached out and gave Zhang Lan's upturned bottom a smack, and shouted loudly.

"Get up right now, you idiot!"

Zhang Lan winced in pain, her whole body shuddered, and she immediately sat up. She shook her head and looked around before fixing her gaze on Wang Kai's face. She had intended to greet him, but in an instant, she understood what was going on, especially given their current position—one on top of the other—making it too difficult to ignore.
