My Crazy Upgrade System

As the outside world gloated, watching and waiting for the Celestial Cloud Empire to be destroyed, Yi Tianyun had just about finished his preparations. At that moment, a guard rushed in from outside.

"Your Majesty! The Divine Generals of the World Dragon Empire are leading a massive army this way! They will arrive in less than half a day…" The guard's face was pale as he knelt on the ground. Even though he had long known this would happen, the reality of the situation still filled him with terror.

This was the World Dragon Empire, the first-ranked Empire in the Mortal Realm! Most people had no idea how powerful the forces of the Netherworld were, since none of them had ever been there.

However, most people knew which was the First Empire of the Mortal Realm, and that carried a completely different weight.

'Straight for the Imperial City, huh? I suppose that's decent of them, not conquering our cities one by one.' Yi Tianyun's gaze turned cold. If they had invaded city by city, it would have been an all-out invasion.

They were now striking directly at the Imperial City. It wasn't because they had noble characters, but because once he was dealt with, the result would be the same as the entire empire falling. If an Empire's Great Emperor was dead, or if all its high-level figures were killed, then the Empire was basically an empty shell.

The other cities would inevitably surrender one after another, choosing not to put up a stiff resistance. The previous advance of the Four Great Empires was largely driven by their arrogance!

Relying on their formidable strength, they had wanted to press forward step-by-step, eventually sealing off all escape routes and leaving the Celestial Dragon Empire with nowhere to run. The World Dragon Empire was being more direct and brutal, coming straight for the Celestial Cloud Imperial City without wasting any time.

"They're here." Yi Tianyun stood up and quickly flew out of the main hall. 'The report just came in, and they're already here?'

The guards exchanged terrified glances. How did they arrive in the blink of an eye? Clearly, the intelligence was wrong; the enemy's speed was far faster than estimated.

The next moment, Yi Tianyun appeared outside the city walls. The guards on the walls had already sounded the alarm, but he simply raised a hand, gesturing for them to stop. The wailing of the alarm quickly fell silent.

He looked up and saw five figures flying toward them at high speed, tearing through the thick clouds as they charged over. In a matter of moments, they were in front of them, hovering just outside the city walls.

The five individuals stared coldly in their direction. Each one possessed an astonishingly high cultivation. The two in the lead were shockingly Spirit King Stage experts. The weaker one was at the Sixth Level of the Spirit King Stage, while the stronger had reached the Seventh Level.

Sending out two Spirit King Stage experts at once was an extremely grand gesture. Moreover, they were at the latter stages of the Spirit King Stage. It seemed they were confident they had them in the bag.

The other three were Void Spirit Stage experts, also at a relatively late stage of their cultivation.

'People from the Celestial Nether Divine Kingdom?' Yi Tianyun's gaze turned cold. One of the old men among them possessed the aura of the Celestial Nether Divine Kingdom, which was laid completely bare under his Eye of Investigation.

'I was just wondering if the World Dragon Empire had ties to the Celestial Nether Divine Kingdom. From the looks of it, they certainly do. They're the ones pulling the strings.'

"Th-That looks like the World Dragon Empire's Profound Dragon Divine General, and the Profound Tiger Divine General… Th-They both came?"

"N-No, that's right. They are both the most formidable Divine Generals of the World Dragon Empire. They came in person! I've heard that when the two of them act together, they leave nothing but devastation in their wake. They're an unstoppable force!"

"We're finished. The World Dragon Empire is using such a deadly move from the very beginning. Can our Great Emperor possibly stand against them…?"

Both were Divine Generals of the World Dragon Empire who frequently went into battle and had countless illustrious achievements to their names. Wherever they went, the pressure they exuded was so immense that their enemies would often choose to surrender, allowing them to subdue armies without a fight.

One could only say they were too formidable. They were the World Dragon Empire's Guardian Divine Generals!

"Great Emperor of the Celestial Cloud Empire, get the hell out here!" the lead Divine General roared. The deafening roar radiated in all directions as terrifying sonic waves spread out, layer by layer, plowing up the ground before crashing directly toward the city wall!

Just as the wave was about to hit the city wall's protective formation, Yi Tianyun flew up and, with a casual wave of his hand, swatted the terrifying sonic wave away. It dissipated into a gust of wind that swept up toward the sky, scattering all the clouds.

The guards' faces changed instantly. 'A single roar is so devastating? Is this the power of the World Dragon Empire?'

The Spirit Race Ancestor and Ye Qingxuan rushed over. Seeing the five experts, their expressions grew grim. Although they all trusted Yi Tianyun, they had to admit that the pressure from these five was immense. They were deeply worried about Yi Tianyun; if he truly couldn't deal with them, all would be lost.

"Insolent!"

Yi Tianyun swung his hand backhanded. A terrifying power condensed in the Void and shot toward the Divine General. The sudden burst of power, combined with its astonishing speed, caught the Divine General completely off guard. He was slapped so hard he was sent flying!

SMACK!

The crisp, clear sound was no less loud than the Divine General's earlier roar. After being sent flying for several miles, the Divine General managed to come to a halt. The Profound Dragon Divine General's face was already swelling up, and the blow had almost taken his head clean off.

A dignified Divine General, slapped until his face was bruised and swollen, leaving his companions unable to even react.

"Making such a racket in front of my Imperial City. You deserved that slap," Yi Tianyun said, looking at them coldly, utterly fearless.

That heavy slap felt as if it had struck everyone in the heart; it was that shocking. This was the Profound Dragon Divine General, slapped just like that? Was Yi Tianyun simply too powerful, or had the Profound Dragon Divine General just failed to react in time?

He had obviously reacted; he simply hadn't been able to block the attack.

"KILL!"

The Profound Dragon Divine General roared in anger. A phantom of a Giant Dragon appeared behind him, instantly covering his body with a thick layer of Dragon Scales. Even his hands transformed into Dragon Claws. A domineering Dragon's Might was released, as if a True Dragon had appeared before them.

Most who followed this path focused on absorbing the Dragon Race's Essence Blood, and the Profound Dragon Divine General was no exception. Otherwise, he would not be named as such.

He had been slapped the moment he arrived, leaving him both shocked and enraged that he hadn't been able to react. Fueled by his fury, he unleashed his full power and charged at Yi Tianyun.

The Profound Tiger Divine General's heart went cold. He let out a roar of his own as white fur erupted from his body, and in an instant, he transformed into a giant white tiger. His cultivation path was more unorthodox; he had absorbed the blood of a white tiger, granting him a berserk, bestial nature and a strength that was in no way inferior to that of the Dragon Race!

The fight had only just begun, yet the two great Divine Generals had already been forced to unleash their full power. A terrifying sense of crisis welled up from deep within them. After so long fighting on bloody battlefields, they had developed a sixth sense for danger, and the feeling they got from Yi Tianyun was that of extreme peril!

When they were first assigned to this mission, they had been utterly disdainful. Now, they realized how gravely mistaken they had been!
