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

The five of them set out and headed straight for the territory where Luoshumen was located.

Limited by the rules of the secret realm, they could not fly in the air. Fortunately, the five of them gathered enough spiritual power and used their footwork to move very fast.

Luoshu Gate is not far from the territory of the Supreme Sect. It has mountains and rivers, and is covered with trees.

The five people swaggered in without any attempt to conceal themselves, appearing right in the sight of the three from Luoshumen.

Lin Du glanced at it, then looked down at the rotating compass, withdrawing his divine sense. "Heaven and Earth Reversal Formation."

"Let's not demolish it yet. After this hill becomes ours, I can modify it a bit and use it."

Lin Du led the four people straight in, without even putting up the concealment talismans he had taken out.

In the blink of an eye, a gentle breeze rustled through the forest, lightly brushing against people's faces, without even causing the hem of their robes to sway in the slightest.

"Why is this '回' formation leaking air...?" Lin Du sensed it for a moment, "The airflow is wrong."

"Isn't that a bit off?" Yuan Ye sensed it for a moment. "Generally speaking, a '回' (hui) formation is a closed formation, but it's possible that there's vital energy of heaven and earth inside, which is not unusual?"

Lin Du shook his head. "Do you know how many ways there are to write the character '回'?"

Yuan Ye looked at Yan Qing blankly, "You've read a lot, you do it."

Yan Qing thought blankly for a moment, "Three kinds?"

Lin Du grinned. "Of the four types, only one is breathable. However, the reason why it is called the '回' (hui) formation is because it is a nested formation evolved from the most basic square formation, which is why it can defend."

"The ones with airflow are wrong." Yan Qing understood. "But Junior Uncle, which one is the fourth one?"

Lin Du blinked. "Does it matter?"

Yan Qing pondered for a while, but was still tormented by his damned thirst for knowledge. "Important."

"It's not important. Don't get so hung up on this and turn into a pedant. You're not going to Yuan Ye's house to take the imperial examination."

Lin Du lazily walked into the formation. "Follow me, and don't make a wrong step."

The four of them followed Lin Du obediently, step by step, until they reached the center of the zigzag formation.

A person dressed in the robes of a Luoshu Sect disciple was bent over, seriously setting up an array. He held a book in one hand, and opposite him were the numbers he had just calculated. He also held the glass ropes that should be buried in the array.

"Qian Qi Li Suo, Gen Gong Fu Tu," Lin Du reminded him, arms crossed.

"Okay." The array master subconsciously responded, but after taking seven steps, he suddenly gasped in surprise and turned to look at the people who had appeared in the array at some point. "How did you get in?"

"So that's why this formation is leaking air. It turns out you didn't set it up properly." Lin Du withdrew his gaze from the paper and sighed softly. "Early stage of the Cloud Ascension Realm, Jin Xuan, go. Yan Qing, watch the escape route."

A long whip cracked in the air, and to the array master's horrified gaze, the whip swirled around him, creating a fierce aura.

"There should be two more people up there." Lin Du thought for a moment. "Tian Wu, Yuan Ye, go take a look, and while you're at it, change their flag. Their blue flag doesn't look good."

"Alright." Yuan Ye replied, releasing a small wooden puppet that looked like a jumping frog. "Go, my jumping frog."

The jumping frog was wound up, but it didn't jump. Instead, its four legs spun rapidly around fixed joints like wheels, propelling it upwards at an extremely fast speed, skimming along the ground.

The array master, who had been cornered by Jin Xuan, still managed to glance at the thing that darted past him, which looked like a mouse.

What do the people of the Supreme Sect call a jumping frog? Their naming is a bit questionable.

Array masters are really not good at fighting, especially when the array is not yet fully set up. Almost without Yan Qing making a move, Jin Xuan alone can force people to have no way to fight back.

Although there is a suppression between the early stage of the Cloud Soaring Realm and the Great Perfection of the Heart of the Qin Realm, Ni Jinxuan's whip was enough to bind the person firmly.

It is quite difficult to forcibly break free from the constraints of a top-grade spiritual treasure.

Lin Du then began to tidy up the original formation, and casually borrowed the materials prepared by the formation master to modify the "回" (hui) shaped formation.

The formation master, who was already bound hand and foot by Yan Qing and Jin Xuan, looked at Lin Du setting up the formation and couldn't help but say, "This isn't a '回' (hui) formation at all."

Lin Du looked up in surprise, "Do you know how many ways there are to write the character '回'?"

Array Master: ?

"What does that have to do with the '回' (hui) shaped formation?"

Lin Du straightened up. "You didn't even finish the outer layer yourself, there's a loophole, didn't you know? This design of mine is based on your original one."

"My formation wasn't finished yet. What kind of formation master wouldn't leave survivors before finishing setting up a formation?"

……

Lin Du looked at him, raised an eyebrow, and said, "Sorry, I won't leave any survivors."

Luoshu Gate Formation Master: I don't believe it.

It is a customary rule for array masters to leave one opening at the end of an array, because they are afraid that the internal energy might be locked up due to accidents before the array is completed, or that the energy might be unbalanced due to errors in the array, causing incalculable consequences. The opening is also a gap, and it is filled in after it is confirmed that everything is correct and the energy is balanced.

Lin Du's decision to leave no survivors is overly confident and will inevitably lead to trouble sooner or later.

No formation master can set up a formation perfectly every time; there will always be some unexpected events along the way.

Leaving someone alive is a way for the formation master to save his own life.

After carefully finishing arranging everything, Lin Du turned to Yan Qing and asked, "Is the one inside the gate returning?"

"Yes, that's the ancient way of writing the character '回'." Yan Qing nodded.

The two looked at the mage in unison, their eyes conveying the same thought: "How pitiful, he hasn't studied enough."

The formation master was silent for a moment. "The basic principles of formation clearly state that the '回' (hui) formation is based on two nested closed frames, making it the most robust defensive formation. Now that you have an opening in the outer layer, how can it be considered a '回' formation?"

Lin Du crossed his arms and said, "Just tell me if it's the character '回' (hui)."

The reason she changed the "回" (hui) formation into an "口" (kou) formation was to change the defensive formation into a trapping formation. It was still a nested formation, except that the inner "巳" (si) formation was a snake-shaped trapping formation, and the nested formation was a maze formation.

I was lucky enough to make it into the escape route. It was indeed a defensive formation with a "回" shape. Once inside, finding another way out would be difficult.

Lin Du was too lazy to reason with this array master. If you set up an array exactly as written in the book, no matter what kind of array it is, it will be broken sooner or later. Otherwise, why are the protective arrays of major sects all composite arrays and new arrays researched and developed by array masters?

The rules are the rules, but how to use them is up to the cultivator, and naturally the effects will vary.

How can a master of formations be so dogmatic?

The fun of formations lies in their ability to manipulate the spiritual energy of everything in the world, transforming their fluctuations into a powerful energy field, thereby achieving countless different and miraculous effects that defy common sense.

The formation master inexplicably felt a huge shock to his decades of studying formations. "That's clearly not a '回' (hui) formation, it's a complex formation! How can you call it a '回' formation?"

Lin Du sighed, "The 'return' I'm talking about isn't the 'return' of the formation, and the 'leaving no survivors' I'm talking about isn't the 'survivors' either."

This person can recite fluently, but you can't joke around with him.

The formation master suddenly felt a chill run down his neck. "You... what do you want to do? This is a competition, you don't actually intend to kill anyone, do you?"

Lin Du thought for a moment, glanced at Yan Qing, and said, "No, I was just joking."

The formation master breathed a sigh of relief. "That's good."

He had barely finished speaking when he felt a sharp pain in his neck, followed by everything going black.

"Even if they're unconscious, they're not considered alive. Just throw them into the trap; it won't bother us when we leave the secret realm anyway."

Yan Qing, dragging the person along, caught up with Lin Du's footsteps, and suddenly remembered, "So, Junior Uncle, what is the fourth way to write the character '回'?"

Lin Du, arms crossed, strode ahead and threatened, "Don't you dare follow the example of the Luo Shu Sect."

"I didn't learn it, I'm very clever." Yan Qing carried a knife in one hand and dragged the unconscious array master through the forest with the other. Their heavy bodies scraped against the fallen leaves and the ground, making a dragging sound.

"So what exactly is the fourth one, Junior Uncle?"

He was almost driven mad by his insatiable thirst for knowledge.
