My Crazy Upgrade System

The Netherworld Empire was famous for a grand formation known as the Nether Dragon Formation. Many had heard of it, but none had ever seen it. This Nether Dragon Formation was incredibly formidable, a Grandmaster-level formation that was considered nearly impossible to break.

Anyone who had seen it never lived to tell the tale.

Nether Dragon Formation: A Grandmaster-level formation that draws upon the Nether Dragon Power from deep within the earth, transforming it into a Nether Dragon phantom to attack. It can also spew Netherworld Fire, destroying everything. Its power is equivalent to a cultivator at the second level of the Void Spirit Stage, with a comprehensive Combat Power of 37,000,000. Weakness: Destroy the formation, or use a Yang Fire to eliminate the Nether Dragon.

The Nether Dragon summoned by this Nether Dragon Formation was a level stronger than the one Yi Tianyun could summon. This didn’t mean the Celestial Dragon Treasure was inferior; rather, it was because Yi Tianyun was still unable to unleash its full power. There was also a significant difference between them: the Celestial Dragon Treasure could protect the Celestial Dragon Empire, whereas this Nether Dragon Formation couldn’t create a shield to protect the Netherworld Imperial City from all attacks.

"This is the Nether Dragon Formation. As long as the formation itself isn’t destroyed, the dragon is essentially immortal..." The Spirit Race Ancestor’s expression was grave. This was not something that could be dealt with easily.

"So we’ve come to his home turf. He has the complete advantage here. It’s not the least bit inferior to the Celestial Dragon Treasure." Ren Long’s face was solemn. He had long known that the National Preceptor was formidable, but seeing this firsthand, it was just as the rumors described. Only on his own territory could the National Preceptor be considered the *true* National Preceptor!

Outside, he could only be considered a powerful expert with a decent cultivation level, not a National Preceptor. Only within the Netherworld Imperial City was he truly a National Preceptor—the preceptor of an empire.

Their expressions were all grave, but their minds were already racing, devising numerous solutions.

"Spirit King, allow me to break the formation. Once I destroy it, I can suppress this Nether Dragon. If it isn’t destroyed, the Nether Dragon will remain in a state of frenzied attack and will cause us great harm!" the Spirit Race Ancestor suggested.

This was similar to summoning the Celestial Dragon; if the creature wasn’t restrained, it would continuously attack everything around it. Its cultivation might not have been exceptionally high, but its advantage was its immortality. Its relentless assault could cause immense damage.

"No need. A mere worm like this is no challenge for me at all." Yi Tianyun smiled nonchalantly. "Breaking the formation is too slow. If I just crush this little worm, there’ll be no problem."

Everyone was stunned for a moment. Could it be that Yi Tianyun planned to transform into that Evil Dragon?

Yi Tianyun hadn’t even moved, but the Nether Dragon was already roaring toward them. The sight of its massive body made everyone’s face sink. The National Preceptor had already ordered the Nether Dragon to attack while they were still discussing their plan. He certainly wasn’t going to wait for them to finalize their strategy before striking.

"Have a taste of the agony of being hounded by the Celestial Dragon—something you can’t kill no matter how hard you try!" The National Preceptor’s gaze was frigid. He had been plagued by the Celestial Dragon before, and now he could finally make his enemies suffer the same fate.

Once the Nether Dragon Formation was activated, the dragon could move within a large area, allowing it to attack from a great distance.

Everyone prepared to move and block the Nether Dragon, drawing their weapons. Just as they were about to charge forward and attack, Yi Tianyun held out a hand to stop them, saying calmly, "Leave it to me."

After speaking, he took a step forward and abruptly raised his hand. FWOOSH! A flame ignited. It wasn’t large, just a small flicker about the size of a fist. It seemed rather inconspicuous, and one could only faintly feel its scorching heat.

Seeing that the Nether Dragon was about to strike, Yi Tianyun remained perfectly calm, a single flame flickering in his hand. As the Nether Dragon opened its maw to bite down, Yi Tianyun gently tossed the flame forward, and it fell right into the dragon’s massive mouth.

As everyone watched, many of the enemy soldiers burst out laughing.

"A tiny little flame dares to compete with the Netherworld Fire? That’s a death wish!"

"Nether Dragon, swallow them whole! Kill these invaders!"

"A bunch of idiots. Let’s see them survive this! The Netherworld Imperial City will never be conquered!"

They had absolute confidence in the Nether Dragon. In their eyes, the Nether Dragon was invincible, utterly immortal. Therefore, tossing such a small flame would have no effect; it would only add fuel to the Nether Dragon’s fire.

The National Preceptor let out a sneer. "Fire against fire... I’ve seen idiots, but I’ve never seen an idiot like this..."

They watched as the Nether Dragon swallowed the flame in one gulp and continued to charge with its jaws wide open, aiming for Yi Tianyun at the very front. Behind him, the Spirit Race Ancestor’s expression changed, and he instantly moved to rush forward and help. Besides the Spirit Race Ancestor, Ren Long and the others also unhesitatingly charged forward to help. Even though they knew Yi Tianyun’s cultivation was stronger, their protective instincts took over.

FWOOSH!

The moment the Nether Dragon lunged to bite, it suddenly burst into flames. The entire massive Nether Dragon began to burn furiously, starting from its head and spreading downward. Soon, the entire dragon was alight, completely transformed into a massive ball of fire!

A moment later, the Nether Dragon was burned to ashes. Even though it was made of pure energy, it was burned away to nothing. All that remained was a large mass of Immortal Fire that fell from the sky like a cluster of fireballs, crashing into the surroundings and setting the ground ablaze.

In the blink of an eye, the area turned into a sea of fire, scorching the earth. Under the heat of the Immortal Fire, many of the formations began to crack, looking as if they were about to collapse.

"I told you I didn’t need any help. Just leave this to me. How dare a mere worm act so presumptuously before me?" Yi Tianyun smiled faintly, then walked forward into the area covered by the grand formations.

This scene left everyone dumbfounded. A single, tiny flame had managed to burn away such a massive Nether Dragon. It was simply unbelievable! The small flame should have been the one to be devoured; instead, the entire Nether Dragon was incinerated.

"How is this possible? How could my Netherworld Fire be unable to deal with that tiny wisp of fire!" The National Preceptor was utterly shocked. He had sensed that the small flame was weak, but he never expected it to be so unbelievably domineering!

The Immortal Fire was, after all, a Fire of Supreme Strength. The Netherworld Fire was a more pliant and gentle type of flame, but it was a far cry from a true fire of supreme softness. Countered by the Fire of Supreme Strength, it was instantly annihilated.

Yi Tianyun didn’t bother to waste a single word answering him. Instead, his eyes flashed, and a blue light glimmered in his pupils as his Celestial Eye opened instantly. What appeared before him was the vast expanse of Grandmaster-level formations. While he might find it difficult to successfully repair or inscribe them, destroying them was far simpler than creating them!

What he wanted to do now was destroy the formations here and shatter this line of defense!
