Chen Wentian left Wu Qianyu on her own to continue her missions. She was more than capable of handling herself, especially with the two treasures she carried. He headed out of the province at full speed, heading for the Immortal Association to research cultivation of emotions.
The Immortal Association had publicly available cultivation resources for immortals as they all still had to cultivate after entering the Spirit Lord Realm. There were many more realms above and much greater lifespans to aim for. Some beginner immortals tied themselves to stronger immortals for guidance and resources, such as those within Beast God Sanctum. Independent immortals like him could still make use of a limited number of resources provided by the association. However, there is no free lunch in this world and Chen Wentian would have to pay to access the resources.
Chen Wentian traveled across several provinces in a day, taking multiple teleportation arrays, and finally arrived at the continental branch of the Immortal Association. It held a large and ancient library for independent immortals. For the low price of a hundred kilograms of red spiritual crystal, he was allowed a single day within. Wasn't it so generous of them?
He was already in a bad mood as he entered the vast halls filled with thousands of tomes. Looking at the books, stacked wall to wall, he felt a massive headache starting. Maybe there was an immortal out there that cultivated by reading but this was never his specialty. He grumbled a bit, thinking about the amount of work he put in for his disciples. He was probably the best master in the whole world!
Since he had already paid, it was not good to waste time. He zoomed over to the closest shelf and started flipping through books.
"Hmm..."
"Nope..."
"Useless..."
"Sword art again... No!"
In the blink of an eye, half a day had passed. There were no books on cultivating one's emotions. It was indeed an archaic path. Most paths dealt with popular aspects such as martial arts, weapon arts, or elemental arts. It felt like at least a quarter of the books in the entire library were on a wide variety of sword arts. It was all just waving a piece of metal around, why is it so popular?
He eventually was able to find something interesting. It wasn't even a book but a painting. It was very old but showed the faded image of a female along with a few words. He couldn't tell but she must have been very beautiful because the painting claimed her to be the goddess of love. He scoffed but continued to read.
'Love yourself and you'll be able to love others. Let them love you and you shall understand their heart. Embrace love and turn it into the source of your power.'
That was all that was written on the painting. Chen Wentian felt those weird sentences were important and read them over and over again. They were pretty obvious statements on the surface but instinctively he had a feeling that they held a deeper secret that could be related to cultivating the emotion of love and other emotions as well. He forgot about the rest of the books as he studied the painting and the words intently.
Unfortunately, the luck god was not with him or maybe he had no talent in this area. He still wasn't able to decipher the words as his time was about to expire. He didn't want to leave empty handed but nothing else could be done. He headed back towards the entrance and was about to leave when a particular book's title caught his eye. He didn't know why he looked in that direction but it was like the book was calling out to him.
It was simply titled 'Pleasure and Pain'.
"What?"
Chen Wentian suddenly thought back to that day with Lin Qingcheng where she had an orgasm while he spanked her. He quickly grabbed the book. His eyes became wide as he flipped through the pages. He felt his mental horizons broadened beyond what he thought was possible. This book was not about cultivation at all and was merely an erotic novel written by a terrible writer. Yet, it completely absorbed his attention until he memorized everything inside.

Chen Wentian finished his research into the subject area described in the book several days later. He finally had all the information he needed. His spatial bag was filled with a large of amount of new and interesting items and his head was filled with new and interesting ideas. He had delved deep into some questionable places and interacted with some truly depraved characters. In the end this was for cultivation. He could justify everything for the cultivation of his disciples!
It only took him another day to arrive at Moonlight City where Lin Qingcheng was. He wanted to try out his newfound knowledge on her first since she had been receptive to a bit of light slapping. He was so excited he didn't even bother to hide his aura as he shot down from the sky and entered the House of Paradise. He found Lin Qingcheng in a meeting hall with several of her managers.
"Master!" Lin Qingcheng cried out in surprise.
"Sir immortal!" The female managers all stood and bowed.
"Qingcheng, I need you for an urgent matter."
"Understood," Lin Qingcheng turned to her people, "You're all dismissed."
"Yes, madam!" The women hurriedly left the room.
When they all left, Lin Qingcheng leaped into his arms. She hugged him tight, having not seem him for close to three weeks.
"Missed me?" Chen Wentian chuckled.
"Mmm." Lin Qingcheng only hugged him tighter, as if to say he shouldn't have left her for so long.
"Alright, alright." Chen Wentian let her be for a while until she finally let go, "Better?"
She nodded, "Master, if you leave me for so long again, I'll go fight demons with elder sister Qianyu!"
"Hahaha!"
"I'm serious!"
They chatted about random things for a while before Chen Wentian broached the main subject. "Qingcheng, the reason I'm here today is that I want to try an experiment with you."
"Hmm?"
"You remember the time when I spanked you and you enjoyed it?"
"Master!" Lin Qingcheng smacked his shoulder and turned away in a huff.
He felt for a second that he might have misjudged the situation but then he saw the sly smile on her lips.
"Naughty girl..." Chen Wentian hugged her intimately and said softly, "Chengcheng, please?"
"No..." She pretended to protest.
"Chengcheng, it's an experiment... using this." He drew out a shiny wooden paddle that was twice as big as his hand. "This will hurt a bit more but I think you'll feel even more pleasure. Trust me!"
She looked at the large paddle with apprehension but she also remembered the feelings and pleasure from that day. A paddle twice as big could maybe increase her pleasure twice as much? Thinking about how it might increase her cultivation even faster, she finally agreed.
