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

Suddenly, the volcano erupted, spewing out lava that stretched endlessly, instantly covering the entire mountain where Lin Du had previously set up his formation.

Thick clouds filled the sky, and crimson currents surged, almost completely obscuring the figure of the blue-robed cultivator hanging in the sky.

In this scorching world, Lin Du remained remarkably calm.

"What a pity," sighed a top-tier formation master in the alliance.

After all, she had paid close attention to Lin Du and discovered that she had laid out a very, very long line, almost unprecedented in length.

It was because they were too ambitious and wanted too much that they failed.

If one is down-to-earth and only completes what is within the map's scope, one might succeed in one fell swoop and compete with Kaiyang for the top spot.

But the next moment, everyone stared wide-eyed in disbelief, "That's...!"

"It's a traffic-driving strategy! It's a traffic-driving formation!"

"Lin Du diverted all the lava from the volcanic eruption!"

"No, no, Lin Du activated the volcano ahead of schedule! This was planned!!"

Amidst a cacophony of exclamations, lava erupted in the area where Lin Du was located. Instead of any irregular, leaping eruptions, it flowed slowly along the laid-out lines.

That speed wasn't slow; in fact, it could be described as fast.

Under wave after wave of impact, the magma rapidly spread to both sides.

Everyone held their breath, watching the lava surge forward, engulfing all the movement paths where Lin Du had once stopped and set up his formation.

"So... Lin Du deliberately used the power of the volcano?" one person asked hesitantly.

"Yes!" A formation master from the alliance clenched her fist, her eyes gleaming with excitement. She advocated that formations should originate from nature and make good use of natural rules to set up formations, so Lin Du's actions were exactly what she wanted.

"But how can she be sure that the magma is useful for this formation? What if there are some unexpected impurities in it that could ruin the entire formation?" one person asked, puzzled.

Formations require precision; Lin Du's approach was far too bold and risky.

A demon cultivator specializing in formations affirmed, "This child is good; he has the style of our demon race."

"Could Lin Du have controlled the pressure and temperature of the eruption and used an array to reverse the flow?" someone asked in a low voice. "It can indeed be controlled using an array."

But is it really possible for someone to achieve that level of skill?

Just as everyone was discussing this, Lin Du's figure broke through the thick smoke, and then a heavy snow began to fall.

The snowfall was incredibly magical; centered on Lin Du's location, snow fell heavily around the volcano, almost completely obscuring everything.

Under normal circumstances, such forced cooling would certainly cause problems, but the snow in Lindu is the purest cold snow in the world, enough to suppress this not-so-pure fire, and in an exceptionally forceful way, it forcibly cooled and fixed the magma.

The further away from the volcano, the thinner and slower the snowfall, decreasing from blizzard to light snow, with the time it takes for the lava to solidify being exactly the same.

From a distance, it looks almost like a pure snow line.

Below the snow line, a line of defense is slowly taking shape.

As the snow gradually stopped, Lin Du's figure slowly came into view. Because of the volcanic eruption, she was wearing a mask, only revealing the upper half of her face. The somewhat dark leather mask with silver trim concealed the smile on her face, and at a glance, one could only see the confidence of someone who had the overall situation under control.

Silence reigned before the water mirror.

"So... is the formation complete?"

After a long while, someone cautiously asked.

"Why don't we go and see for ourselves?" The members of the Array Masters Alliance stood up in unison.

Upon arriving at their destination, the group had not yet realized the vastness of the array; they simply took out their array plates in unison.

"It's done! It really is done!" a top-tier formation master exclaimed in delight. "It really is done!"

The formation was somewhat unexpected, similar in principle to the hidden formation underground, yet different in some ways.

Because the magma is fixed, serves as a shelter, and is also one of the formations.

The human design, employing the skill and ingenuity of nature, achieved three goals at once, leaving everyone speechless with amazement.

What's even more impressive is not just this single, well-executed move.

"This formation! It's so long!" The person who measured the range of the formation returned after a long time, his eyes filled with shock. "Everyone, please come with me to the air to take a look."

Everyone was simultaneously lifted into the air, gazing into the distance, and were all speechless with awe.

Unlike the shock of being overwhelmed by the sophisticated and advanced array just now, this was a pure, visual shock that even a child who had not yet entered the Dao could see at a glance.

This line of defense resembles a coiled dragon, with its head positioned in the very center, precisely where the volcano is located.

How long is it? It stretches endlessly, with undulating peaks and valleys, so long that even a cultivator at the Cloud Ascension Realm cannot see its end.

"A total of six thousand li, a full six thousand li!!!"

The person taking the measurements had a tense, hoarse voice, not because they were running too fast, but because they were extremely excited.

This is almost the longest formation ever set up by a single person.

And this formation, even a section of it, cannot be moved or destroyed.

Because of its unique method of securing the lines, which used cooled magma, all the battle lines were buried underground, not in soil, but in rock.

Six thousand miles—this means that Lin Du alone completed a defensive line that would require five top-grade array masters, or even dozens of ordinary array masters, to complete.

Along this route, there are mountains, deserts, and grasslands, but this line of defense is incredibly strong and stretches for thousands of miles.

A thousand miles is a huge challenge, and connecting each sub-array alone is a tremendous test. But in fact, the array master carried the array plate all the way along the entire line without breaking the connection at any point.

More and more people are gathering here, including some of the participants.

The members of the Array Masters Alliance wrote a note after Lin Du's name: Heavenly Grade, Ninth Rank.

Now, it has become a difficult question again whether Lin Du or Kai Yang is the leader.

One is long and the other is strong; each has its own advantages.

"This formation does indeed cover a wide area, but," Kaiyang laughed, "things that are too long are always easy to break, and since you used solidified lava to fix it, it is inevitably difficult to repair."

"It's a bit impractical." He said, looking at Lin Du. "Of course, you've done your best with this length, but according to my estimate, your formation can only last for two hundred years at most."

Lin Du looked up; her mask was still on, and her gray eyes appeared unusually cold and sharp. "I said, have you even seen the question?"

Kaiyang, not understanding his meaning, replied, "Of course I've seen it."

Lin Du nodded. "The topic for the final is: The demons of the Dongming Realm have stopped their internal strife and have repeatedly harassed the borders of the spiritual cultivation world, feeding on and enslaving the spiritual cultivators. In recent years, they have even gathered together, wanting to seize the spiritual cultivation land. Now, the array masters of the array master conference, please design a large array at your chosen location that can defend against the demons' advance."

She read the questions aloud in perfect pronunciation, much like she was broadcasting a report on her hearing to friends outside the city.

Kaiyang looked somewhat helpless. "So?"

"This is a practical application problem, and the criteria for judging it are strength, breadth, and practicality." Lin Du slowly removed his mask, "So no matter how profound your formation is, you must consider practicality."

"The fact is that my formation, and the formations of many people here, can last longer than yours without being replenished." Kaiyang felt that Lin Du was just young and arrogant, stubborn and unwilling to admit defeat after being humiliated.

This is understandable.

"Wrong. The truth is, my formation is meant to last until the day the evil spirits perish." Lin Du slightly raised his chin, a smile playing on his lips, his eyes resolute. "I don't care if your formation lasts for thousands or tens of thousands of years. In a hundred years, all the formations here will be dismantled."

"I said it."

Kaiyang asked, puzzled, "What do you mean?"

"What I mean is," Lin Du raised his hand, tossing the mask in his hand up and down, "that a hundred years from now, all the evil spirits in this Dongming Realm will be gone, that's what I'm saying."

Kaiyang laughed after hearing this, "What's the use of what you're saying? This demonic energy has been dissipating for nearly 100,000 years. You're all used to the existence of the Demon Realm. How could you possibly completely wipe it out within a hundred years?"

"Even if you really did kill the demons within a hundred years, there would still be residual demonic energy, which cannot be eliminated by spiritual energy in a hundred years."

"Where there is demonic energy, there will always be special natural formations that allow evil to be reborn."

His words all sounded objective, but Lin Du laughed, "So you don't understand the Realm of Insight."

One sentence caused the smile on Kaiyang's face to slowly vanish, and his tone became somewhat tense, "What...what do you mean by this?"

Lin Du raised his eyes, deliberately widening them. "It doesn't mean anything. Someone suddenly appears out of nowhere, without a master or a hometown. They must be a recluse who doesn't understand the situation in the Insight Realm. Isn't that normal?"

Kaiyang's stiff body relaxed imperceptibly. "This time, I didn't win..."

Before Kaiyang could finish speaking, Lin Du deliberately interrupted him, "The reason I came here to design this Great Wall Formation is not only to win the championship, but also to stabilize the border, to ensure the peace of the spirit realm, and to ensure the people live in peace. Therefore, the longer my formation can cover, the better."

"The longer the line, the greater the chance that others will complete it later, and the more peaceful the border will be. Not to mention my six thousand miles, the entire border of the Demon Realm is forty thousand miles long, plus the natural barrier line, we will definitely be able to surround the Demon Realm."

"Next, that will be the battlefield for us high-level cultivators to cleanse the demons."

Kaiyang's tone was gentle, but his smile became somewhat frivolous. "A grand yet practical ideal."

Lin Du made no attempt to hide his ambition. "No, it's true."

"Any advanced algorithm is irrelevant in the face of reality." Lin Du raised his hand. "I'm just stating a fact."

"Then the Grand Competition of Array Masters, which seems to be connected to reality, has deviated from its original pure purpose," Kaiyang retorted.

"No, all creation is for the progress of life, and all theories should be put into practice." Lin Du stood firmly, his aura unyielding.

"Regarding the issue you raised about not being able to replenish energy, that's actually possible," Lin Du said with a smile. "Volcanoes erupt, and with a secondary eruption, they can continue for another hundred years. Tell me, could a volcano erupt multiple times under the interference of a formation master?"

"So, at least you misjudged the situation." Lin Du's voice remained calm, and his volume was not loud.

But as soon as these words were spoken, everyone suddenly realized what was going on.

This was actually the main reason why Lin Du used a volcano as the core; the power and spiritual energy hidden beneath the earth's crust served as a supplement to the formation's energy. It was indeed the most ingenious method.

"Lin Du is undoubtedly the master of this formation," someone remarked.

If its advantage was previously its length, now that all aspects have been considered, there is nothing wrong with it anymore.

Kaiyang turned to the alliance leader, "I heard that when the leader of the array formation changes, the work needs to be compared with the previous winner's, is that right?"

After Yan Ye, several more conferences were held, but the title of champion was still Yan Ye.

Lin Du lowered his eyes and tapped his disciple token; so this was his purpose.

The good news isn't directed at her.

The bad news is coming from her master.

If this is how the formation competition is conducted, what about other major competitions?
