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

Lin Du pried off Han Yue Ling, ignoring its grumbling complaints through the spirit contract, turned around and went downstairs. On the stairs, he saw Hou Cang with a cold face that looked like he was about to draw his sword and kill someone.

Even though you didn't do anything wrong, every mosquito that passes by owes you eight million.

"Let's go, senior brother."

Hou Cang stiffly got up to pay the bill. Because of Lin Du's status, he couldn't really teach her a lesson. Finally, he managed to say, "I'll tell Senior Sister exactly what happened when I get back."

Unable to be hit or scolded, I decisively chose to tell my parents as the ultimate solution.

"Okay, okay, senior brother, go ahead and tell me. But before we do, let's grab a late-night snack, or my rabbits will rebel." After Lin Du finished his perfunctory reply, Cang had to go along with the rabbits that had just been used to block surveillance and eavesdropping. "You can eat anywhere on the street."

Hou Cang really wanted to leave, but his master told him to take his junior sister home safely, so he could only eat his way through the entire night market with Lin Du.

Other things aside, what kind of good family's rabbits even eat roasted rabbit meat?

Hou Cang despaired of this abnormal world.

After Chu Guanmeng finished eating all the different kinds of food, she slumped onto Lin Du's shoulder to aid digestion.

"Are you full? You've almost eaten the whole street. Luckily I exchanged some low-grade spirit stones, otherwise I would have had to use high-grade spirit stones directly. These vendors can't keep change."

"This is my reward," Chu Guanmeng said matter-of-factly. "Do you know how much power it takes to create an illusion?"

Lin Du nodded, "I understand, I understand."

Chu Guanmeng suddenly remembered something, "Aren't you very poor?"

Lin Du nodded, "I am very poor, just like you said, my house is bare."

Hou Cang was speechless when he heard the conversation between the man and the rabbit. Yes, they were poor, so poor that they could only afford high-grade spirit stones and spirit crystals, and didn't even have low-grade spirit stones.

Anyway, Hou Cang didn't believe it, but Chu Guanmeng did.

Feng Chao didn't say anything about Hou Cang's complaint. After everyone left, he asked Lin Du, "What clues did you find at the brothel?"

"A little, not much."

Lin Du slumped onto the stool. "I want to do something big."

"Will the Heavenly Dao cease to function without the Demon Race?"

Lin Du sincerely raised a question.

Feng Chao thought about the problem seriously. "Some people have tried it before, but the sealing time is limited, and if there are fewer demons, they will shift their focus to spiritual cultivators, which will cause frequent disasters on the border of Zhongzhou."

Lin Du frowned. "What if I seal off the Demon Realm?"

"You have a lot of ideas." Feng Chao had a thousand words on the tip of his tongue, but in the end he could only manage to utter this sentence: "But they're not very feasible."

Lin Du stood up, pulled up the map of the Central Cave Bright Realm in Feng Chao's study, highlighted the territory of the Demon Realm, and looked at it carefully. "It's not without its feasibility."

Because spiritual energy and demonic energy consume each other, a long "vacuum zone" appears between the demon realm and the spiritual cultivation territory. There is no spiritual energy or demonic energy, and it is arid and waterless, with many canyons and wastelands, which is called the desolate desert.

"With your current strength, it's not enough."

Lin Du laughed, "Indeed, I didn't say I would rely on myself."

She looked at Feng Chao, "Even if we only block a portion of it, and let the demons fight amongst themselves, it will still be enough."

Feng Chao didn't follow his junior sister's train of thought. "With your current skill in array formations, you can at most block a small valley, and your master would never do that."

For thousands of years, it's not that no one has thought of this, but the cost is too high and the gains don't outweigh the losses.

"Senior sister forgot that in eighteen years, the once-in-a-century Array Master Competition will begin, and before and after that, there will be the Weapon Refiner Competition and the Mechanical Art Competition."

Feng Chao still didn't understand. "What does this have to do with your thoughts?"

"This is of great importance. In previous years, the array formation competitions were nothing more than internal strife within the Central Plains. But now that the demonic tide is about to begin, why don't we broaden our perspective?"

Lin Du pointed out those desolate, sandy plains, "What if all these competitions were held here? And what if the challenge of each competition was to block and weaken the demons?"

"The strength of one person is insignificant, but each competition involves tens of thousands of cultivators, all of whom are elites in their field. If every cultivator contributes their share, then many grains of sand can form a tower. A single competition can create a Great Wall to keep out evil spirits. What's wrong with that?"

A long line, gleaming with golden light, stretched across the massive map array. Lin Du stood before it, her brocade robes shimmering with golden light. She turned to look at Feng Chao behind the desk, placing one hand on the defensive line, as if giving it a real skeleton. The golden light transformed into concrete tower defenses.

"This is the true value and meaning of the competition. I want this competition to be absolutely free of any stones or materials."

"I'm sure the leaders of these alliances will accept this proposal, Senior Sister, what do you think?"

Feng Chao stared intently at his junior sister, his phoenix eyes sharp. "You specifically told me all this because you want me to write a letter to the alliance leaders, so that my involvement would carry more weight?"

Lin Du chuckled, "Senior Sister, you're the sect leader! The sect leader of the number one sect in Central Continent! The laws and regulations of Central Continent were also established by our sect, so it's most appropriate for you to speak."

"Now the scope of things has been broadened!"

Feng Chao finally couldn't help but laugh, "Okay, okay, I'll write it now."

Lin Du smiled even more broadly, "Senior Sister is the best! I'm off then!"

"Stop!" Feng Chao called out to Lin Du. "You've thought it all through, of course you'll write it yourself and then stamp it with my seal."

Lin Du's foot, which had been happily stepping out, froze on the threshold. He turned back in despair, "Huh?"

Feng Chao pointed to the small table next to him, "Go."

Lin Du withdrew his foot. "Wait a minute, I'll find someone to help with the finishing touches."

So, in the dead of night, Yan Qing rushed over from his cave, his face still sleepy. "Junior Uncle, what did you write this time? Wasn't the last one very effective? The Demon Lord would be furious if he saw it and would definitely find that person and tear him to pieces."

Lin Du smiled and said, "It is well written, so I wrote another one, but this one is for the leader of your Weapon Refiner Alliance."

"Oh, huh?" Yan Qing's eyes widened. "What kind of status or rank do I have that I'm writing a letter to the leader of the Weapon Refiners' Alliance?"

"You were a ghostwriter."

"Oh," Yan Qing sat down, "Hmm? Whose pen is this? Is this appropriate?"

"Sect Leader." Lin Du smiled and handed over a pen. "Imagine you are the Sect Leader of the Supreme Sect. You would write a letter to the leader of the Weapon Refiners Alliance, persuading him that with the impending demonic tide, you should propose setting the Weapon Refiners Competition in the desolate desert and setting the competition around the theme of blocking and intercepting demons invading spiritual cultivation territory. This would test the abilities of the weapon refiners and also ensure that the materials used in the creations are not wasted, as they can all be used to protect the cultivators and their homeland."

"Please begin answering the questions."

Yan Qing rubbed her face to make sure she hadn't misheard, then stood up. "Wait a minute, Junior Uncle, let me warm up and clear my head so I can write in the best possible condition."

Lin Du was satisfied, lowered his head, and began to write.

If you can't lead a team, then you'll have to work yourself to death.

The scope has been broadened!
