My Crazy Upgrade System

Although the Nether Dragon was easily set ablaze, the Nether Dragon Formation wasn’t limited to a single point. It was far more flexible than the Celestial Dragon Treasure, but it lacked a bit in raw power. Its current state was already its limit, and the consumption was staggering. At most, it could only control one Nether Dragon; any more than that was impossible.

As for the Celestial Dragon Treasure, anyone it acknowledged as its master could control it. As their cultivation level rose, they would be able to control even stronger Celestial Dragons.

In terms of tier, the Celestial Dragon Treasure was undoubtedly far superior. The only issue was that it was extremely difficult to control. If it didn’t acknowledge a master, it was completely useless.

When the Nether Dragon was killed, the Nether Dragon Formation was damaged. This was the simplest and most brutish way to break the formation. Each time a dragon was completely destroyed, the formation would be damaged to a certain extent, so its weakness was still quite significant.

"Damn it! What in the world is that flame... Again!" the National Preceptor roared. This was his proudest creation, the Nether Dragon Formation. Although it couldn’t compare to the Celestial Dragon Treasure, it was already quite close. For it to be insta-killed so easily left him incredibly resentful.

He quickly took control of the Nether Dragon Formation again, swiftly condensing another Nether Dragon. It came roaring madly toward them, but it seemed a bit weaker than the previous one. After being destroyed once, the formation’s power had significantly decreased.

At this moment, Yi Tianyun’s Celestial Eye began to scan the area, searching for the Nether Dragon Formation’s cores. He wanted to see where they were generally located. As long as he could destroy them quickly, this supposedly terrifying Nether Dragon Formation would prove to be quite fragile.

"There’s a core about a hundred feet to your left!"

Ye Qingxuan’s voice rang in his ear. Without even looking, Yi Tianyun knew she was also using her Celestial Eye to help him find the formation cores. If they wanted to launch an all-out assault, they had to break this formation first, and he couldn’t do it quickly by himself.

The Spirit Race Ancestor followed him into the formation and began searching for a way to break it. Although the Spirit Race Ancestor’s power hadn’t returned to its peak, finding a flawed formation core was no problem for him. After all, he was also a Divine Rune Grandmaster, not just a decoration!

"Good!"

Yi Tianyun’s heart settled. ’Having help makes all the difference,’ he thought. The search speed had more than doubled. Upon locating the spot, a ball of Immortal Fire rose in his hand, and he quickly threw it toward the formation core. With a WHOOSH, the core was instantly incinerated.

Following that, a section of the formation collapsed with a deafening RUMBLE, completely vanishing. This meant the Nether Dragon’s power had dropped by a whole level.

Sure enough, the cultivation of the roaring Nether Dragon immediately dropped to the first level of the Void Spirit Stage, and its Combat Power plummeted. This was one of the disadvantages of a grand formation; if it was damaged, its effectiveness would drop drastically. The Celestial Dragon Treasure, on the other hand, wouldn’t have this problem unless it was destroyed.

But could a Divine Artifact be destroyed so easily? They couldn’t even take it, let alone destroy it.

"Get lost, you little worm!"

Yi Tianyun threw a ball of fire. With another WHOOSH, the Nether Dragon was burned to nothing once again. The dragon’s death damaged the entire Nether Dragon Formation in the area, causing small cracks to appear as its power sharply decreased again.

The National Preceptor’s expression grew uglier and uglier. Anyone who wasn’t blind could see that he had completely lost his advantage. His dreaded Nether Dragon Formation was being suppressed by Yi Tianyun and the Spirit Race as if it were a child’s game. It hadn’t killed a single person, which was definitely a new, historical record.

Wherever the Nether Dragon appeared, bodies were supposed to litter the fields. Yet now, it was just being repeatedly burned to ash while its formation gradually crumbled!

"National Preceptor, what do we do now? If this continues, our Nether Dragon Formation will be completely destroyed..." the National Guardian Grand General said, his face grim. They had made a promise to the Netherworld Emperor. If they couldn’t stop the enemy’s attack, they would rather commit suicide than flee.

"It seems we have no choice but to fight ourselves..." Golden light flashed in the National Preceptor’s eyes. The Divine Runes all over his body began to emit waves of light, followed by a series of BANGS. As the Divine Runes detonated, the National Preceptor’s aura grew increasingly formidable. This was the same effect as when the ancestors in the Divine Rune Mansion had detonated their Divine Runes; their methods were essentially identical.

They had all carved stacks of Divine Runes onto their bodies. Upon detonation, the runes would release their maximum effect, comprehensively enhancing their own power to an astonishing level.

This meant the National Preceptor was truly about to risk it all. He wanted to unleash his strongest power to deal with Yi Tianyun. If he didn’t, it would be a dead end even if he managed to escape. The Netherworld Emperor did not suffer fools!

The National Preceptor then took out a Blood Pill. The National Guardian Grand General standing beside him was stunned. "National Preceptor, you’re taking a Blood Exciting Divine Pill... But... even if you win, your cultivation will regress by a huge margin!"

The effect of the Blood Exciting Divine Pill was simple and crude: it completely stimulated the power of one’s Essence Blood. The side effect was a drastic drop in cultivation that would take a very long time to recover from. It was classified as a Forbidden Elixir, and recovery after taking one was a lengthy process.

The National Preceptor didn’t answer. He shoved the pill into his mouth and swallowed it, only then forcing out a few words. "If I don’t take it and we lose, I die. My cultivation can be restored, but what about my life?"

The moment he finished speaking, he stomped his foot. BOOM! He left a crater in the solid city wall as he charged over, Magic Wand in hand. The Nether Dragon underground instantly shot up and drilled into his body. The next moment, he transformed into a Nether Dragon and bore down on Yi Tianyun.

The sky instantly turned pitch-black, and dark clouds gathered. An oppressive and terrifying power surged toward them. This was far stronger than the previous attacks from the lone Nether Dragon. With all the layers of power stacked on top of each other, the National Preceptor’s Combat Power had reached a level of ninety-eight million!

By combining all of his power, the National Preceptor’s strength reached a heaven-defying level, far surpassing the limits of what he could normally unleash. Indeed, with these layered power-ups, his strength had far exceeded its usual peak.

The Spirit Race Ancestor and the others felt completely powerless. They had the sense that if this Nether Dragon crushed them, death would be certain!

But Yi Tianyun just smiled. "Even if you merge with this Nether Dragon, you’re still just a little worm!"

He laughed loudly, tapped his foot lightly, and shot up to meet the attack head-on. A brilliant light burst from his eyes as he threw a punch through the air at the roaring Nether Dragon.

"Dragon God Fist!"

DONG!

A massive fist of light erupted, transforming into a gigantic fist that smashed upward. In an instant, the light enveloped the Nether Dragon. The very moment it made contact, the Nether Dragon completely dissipated. The National Preceptor was then struck hard by the punch and sent plummeting from the sky like a meteor. He slammed heavily into the ground—BOOM!—leaving behind a giant fist-shaped crater!

An instant kill!

At that very moment, a terrifying value was displayed on Yi Tianyun’s own attribute bar: 176,000,000!
