The entire sect is obsessed with love, but I'm the only one who's truly insane.

It was autumn harvest time again. After Mo Lin and his group finished harvesting the spirit wheat, they changed their clothes and went to Tianrui Peak.

The array set up by Lin Du was soundproof and isolated from the aura, and was a laboratory specially set up for Xia Tianwu to study mutated demons. Ordinary people could not enter or leave.

Mo Lin knocked on the barrier's door, formed a hand seal, and channeled his spiritual energy into it before he could enter.

As soon as he entered, he heard a deafening sound of bones being chopped.

Xia Tian was unaware of Mo Lin's arrival, but had no time to greet him, carrying his axe with a loud thud.

"Don't you usually use a saw? Why are you using an axe today?"

"Let's test it out." Xia Tian chopped down with his axe without much force. "The strength of the demon's bones is amazing."

"That's not how you use an axe to generate force, let me do it." Mo Lin put on gloves, wanting to take her place.

Summer didn't shake her head, "Only I can know the difference by experiencing it myself."

Mo Lin had no choice but to put his hand down; he had almost worn out the storybook.

What are those books like "One Hundred Ways to Win Over Your Daoist Partner," "How to Quickly Become a Master of Love," "The Details of Appeasing People," and "The Master of Language"? None of them work on my junior sister.

My junior uncle said to read more books, but it seems that's useless.

Summer Wu raised his axe high and brought it down again.

"What brings you here?"

"Oh, there's a letter for you." Mo Lin took it out. "It feels very thick. I wonder who it's from."

Boom!

Another loud crash, the axe sank only an inch into the dark red bone, but the wooden table beneath it collapsed.

Mo Lin reacted quickly, catching the table and preventing the items from falling.

Xia Tian made a note in the notebook next to him, then turned around to pack his things and took the letter.

Mo Lin's divine sense quietly landed on it, but he was so shocked by the anatomical diagram and the demon skin that he silently withdrew his gaze.

"It was sent to me by Quan Jiangren." Xia Tian was unaware of Mo Lin's gaze. "I recently finished completing a few spells that still needed further refinement, so I sent him a letter to ask if there was a way to reverse them."

"After all, I still have a demon here who has retained the last bit of sanity. If only there were a way to reverse it."

As she read the letter, her brows slowly furrowed.

"The craftsman said that a demon with half of its intelligence has appeared in the valley, roughly the size of a nine-year-old human. The killer is improving."

"The Chronicles of the Central Plains previously stated that this was orchestrated by the Demon Lord to force the true mastermind to reveal themselves, but they haven't shown up yet." Mo Lin thought of something, "Given the Demon Lord's personality, it's unlikely he would take the blame like this."

"That demon is already very weak." Xia Tianwu looked at the small room not far away. "She can't get food, and she will continue to weaken in the spiritual energy environment. Her soul has been eroded by demonic energy, leaving only a last bit of rationality."

She whispered, "She seems... to regard me as her mother."

Mo Lin exclaimed, "Then, how about we try feeding the baby some raw meat?"

Xia Tian didn't sense anything was wrong, and frowned, "Hmm, I'll try it later."

Her gaze swept over the messy handwriting and stopped on the last page.

"Shall I build you a new table?"

"Wait a minute, let's go find Junior Uncle first." A hint of panic flashed in Xia Tianwu's eyes as he hurriedly opened the envelope, and sure enough, a willow branch fell out.

Mo Lin lowered his head, and long-buried memories suddenly surged up. "That was... a short branch of red willow?"

Lin Du's daily schedule is very fixed, and her location can be accurately found even without telepathy.

When Xia Tianwu and Mo Lin came looking for him, Lin Du was reviewing a chess game in the library. The lamplight was soft and warm, creating a peaceful and serene atmosphere.

"Why did you two come together? Is there something you need to tell me?" Lin Du blinked and smiled, clearly in a good mood.

A willow branch fell in front of Lin Du. Xia Tianwu said, "The Craftsman Quan said that a new demon has entered Kongxiang Valley. One of the demons, who still has the intelligence of a nine-year-old child, has a willow branch hanging from its chest. It says that it is a response to the strategist. The Craftsman Quan said that he guessed that it was not aimed at him, but at... that kid in our team who was full of scheming and plotting that day."

Lin Du squinted at the words carved on it.

"My sins are for the present, but my merits will last for generations. Though I am gone, no one can catch up with me."

Xia Tian stared blankly at his junior uncle's still-smiling face, a chill creeping into his eyes.

Lin Du gripped the chess piece, leaned back in his chair, and looked down at the willow branch that stretched across the chessboard, grinning. This startled Chu Guanmeng, who was hanging on his shoulder, so much so that her hair stood on end.

"The sins are committed in this generation, but the merits will last for generations."

Lin Du took a deep breath. "Wow, that's a really good word."

This was the response from her good senior brother.

They said he was utterly wicked, while he said his merits would last for generations.

Lin Du lowered her eyes, the ruthlessness surging in her heart spreading into her veins, her blood rushing, a strange sense of excitement in the confrontation stirring up her originally calm state of mind.

Wenfu knew that she was deliberately forcing him. Now he was being investigated by both the spiritual and demonic factions, and he would be caught sooner or later.

"Oh right, Uncle-Master, there's also a letter for you." Mo Lin remembered and took out another letter, which looked much thinner.

Lin Du took the envelope and discovered that it was protected by a tight security barrier. She raised her hand and channeled her spiritual energy into it, only to find the problem was, "Want some melon seeds?"

Lin Du: ...This fox is quite creative.

She tried entering her name, but it wasn't correct.

What could it be?

Lin Du tried the name Hu You again, but it still didn't work.

She thought it over and over, and then answered Furongyu.

The password was correct, and the envelope popped open automatically.

I've remembered that hibiscus jade carving for a lifetime!

Lin Du sighed, pulled out the letter, and found that it recorded the names of all the people under the Demon Lord's command, from the left and right protectors to the elders, as well as the lords in charge of various territories, and their hobbies, personalities, and main cultivation techniques.

In his letter, Fox pointed out several suspects: the Right Protector who had never shown his true face, the Fifth Elder who was skilled in healing, and the Thirteenth Elder who was keen on capturing people and torturing demons.

Finally, in the letter, Fox Wanderer said that the message had been delivered, and the demons' hearts were stirred. It seemed that many lords were eager to try, but because the Demon Lord had issued a search order, the various demons did not dare to confirm the authenticity of the message.

Lin Du stared at the letter for a while, a smile of renewed control returning to his eyes. He looked up at his worried nephew and said, "It's alright, I know what I'm doing."

"Is there anything else?"

Xia Tian shook his head. "There isn't any at the moment. Quan Jiangren sent me a new research idea. I'll tell Junior Uncle when I make some concrete progress."

Lin Du nodded. "Okay."

Xia Tian didn't turn to leave, but Mo Lin stood there, a hint of embarrassment on his usually righteous face. "Junior Uncle... your method of reading more books isn't working!"

Lin Du looked bewildered. "Huh?"

Mo Lin gestured, "It's that one. Didn't Junior Uncle say to read more books to accumulate experience? I've read a lot of methods for pursuing a Daoist partner, but it still doesn't work!"

Lin Du gasped, "Huh?"

She rubbed her temples. "What have you been learning?"

"Exactly, pay attention to details, cater to their preferences, and focus on companionship..." Mo Lin pulled out a small booklet. "I even took notes."

Lin Du took the booklet and then confiscated it.

She looked up at Mo Lin and said, "Junior Uncle will teach you a piece of advice: tricks never last, only sincerity wins people's hearts."

Sincerity is the greatest weapon.

"You are all very simple people, there is no need to complicate things."

Lin Du felt he deserved to be called a senior apprentice, and his annual allowance should at least be doubled.

But seeing a man over a hundred years old and 1.95 meters tall standing in front of him with his big eyes sincerely asking for advice, Lin Du had no choice but to help.

She looked at Mo Lin and said, "Intentionally trying to please someone and forcibly changing yourself is not as good as taking things slowly. Everyone has their own way of getting along. We are all independent and complete individuals who can live normally and independently. When two people want to merge their lives, they will inevitably go through a long period of change and friction. But you have lived together for decades. Don't you understand Tian Wu's personality?"

Lin Du returned to his old ways and explained earnestly, "You're straightforward and kind-hearted, and you're warm-hearted despite your cold exterior, so stop dawdling."

She paused, then added, "If she says no, then we should let it go, respect her wishes, and remain good fellow students, understand?"

Mo Lin nodded, seemingly understanding but not quite. "I know. With the demonic tide imminent, she's busy, and I need to focus on my cultivation too. So, let's wait until she's finished!"

Lin Du watched as Mo Lin turned around and picked up his sword and staff to practice his swordplay. After a moment of silence, he turned to look at his chessboard.

She reached out and swept away all the black stones with a willow branch, then got up and walked towards the forbidden area.

How could you possibly shake her resolve to continue her scheme?

Regardless of merits or demerits, she must protect the present person and the future sky.

Lin Du always wanted to have the best of both worlds.

She will definitely go further than Wenfu.
