Gu Changqing looked into the system space and sure enough, a hammer had appeared, which was now floating in mid-air.

Upon closer inspection, he saw that the hammer consisted of a hammerhead and a handle. The handle was dark gold in color and about three feet long. The hammerhead was jet black with a slight sheen, exuding a sense of weight. At first glance, it seemed no different from an ordinary hammer.

But when Gu Changqing actually held the hammer in his hand, he clearly felt that it was different from other hammers. This hammer looked ordinary, but it was actually extraordinary.

The hammer was incredibly heavy, something Gu Changqing hadn't anticipated. He almost lost his grip when he tried to pick it up without warning, because its weight was truly terrifying. Gu Changqing roughly estimated that it weighed a trillion jin, which gave him quite a fright.

This was the first time Gu Changqing had ever encountered such a heavy hammer. It looked unremarkable, so why was it so heavy in his hands? He was filled with mixed emotions.

It seems that you can't judge things by appearances alone, or you can easily be misled.

"Don't let the appearance of the things forged from the smelting of the 'system' fool you; they're actually quite impressive. Holy crap, if I used this hammer to hit someone, wouldn't they be smashed into a pulp? Hahaha, it's truly unique; this hammer is really good." Gu Changqing smugly thought to himself, now he had another tool for killing.

"This hammer is jet black and looks ordinary, but it is the heaviest ever made. Let's just name it the Mighty Black Gold Hammer."

"The host's name is excellent, it's so fitting, so perfect," Green suddenly exclaimed in praise.

"Master, you actually eavesdropped on my conversation, do you want a beating?" Gu Changqing said with displeasure, not expecting that Master had learned these bad habits.

"Greenie was wrong. Greenie was just curious about what name the host would choose. I promise it won't happen again," the system quickly explained and apologized.

"Fine, I'm in a good mood, so I won't hold it against you this time. But if I find out you still have this bad habit, don't blame me for really beating you up. Now get out of here!" Gu Changqing said mercilessly.

"Yes, Greenie will disappear now." After saying that, the system really disappeared.

Gu Changqing's thoughts returned to his mighty black gold hammer. Without saying a word, he used all his strength to lift the mighty gold hammer and smash it into the ruins in front of him.

"Boom!!!"

A tremendous sonic boom resounded, reaching a height of a thousand feet, dazzling with light, and with immense power, smashing down like the creation of heaven and earth!

Suddenly, a terrifying aura swept out like a tidal wave, and the earth cracked open, revealing fissures like ripples on the sea. The land, stretching for billions of feet, trembled involuntarily.

In a flash, the hammer struck the ruins of the mountain, and a deafening sound rang out. The earth trembled and the mountains shook violently, as if a dragon were turning over. Endless rubble tumbled and exploded, sand and stones flew everywhere, leaving a scene of utter devastation.

After the explosion subsided, Gu Changqing looked closely and saw a huge black hole exposed in the ruins. It was bottomless, pitch black, and looked extremely terrifying!

This hammer blow was terrifyingly powerful, causing the heavens and earth to change color and the sun and moon to dim. This shows how powerful it was and how terrifying it was.

Gu Changqing was overjoyed and said excitedly, "Not bad, not bad, it really is a good hammer. The things forged by the system are quite reliable."

What Gu Changqing didn't know was that at this moment, many people in both the lower and upper realms sensed this fluctuation, and their expressions changed drastically.

Holy crap, that's terrifying! Who did this? They're so arrogant!

My God, what's going on? Why is there such a strong tremor? Could it be an earthquake somewhere?

Holy crap, where did this amazing guy come from? He's incredible!

--------------------

Gu Changqing suddenly thought that if he poured his cultivation into this mighty black gold hammer, wouldn't the effect be even more powerful and unimaginable?

Without hesitation, Gu Changqing prepared to give it a try and see just how much power the Mighty Black Gold Hammer could infuse.

Immediately afterward, he focused his mind and poured all his cultivation into the powerful black gold hammer.

A moment later!!!

Greenie's incredibly familiar yet mechanical voice popped into my mind.

"The host has poured 100,000 years of cultivation into the Mighty Black Gold Hammer, causing its power to surge to 100% of its original strength."

"The host has poured 800,000 years of cultivation into the Mighty Black Gold Hammer, causing its power to surge to 800% of its original strength."

"The host has poured two million years of cultivation into the Mighty Black Gold Hammer, causing its power to surge to 2000% of its original strength."

"The host has poured six million years of cultivation into the Mighty Black Gold Hammer, causing its power to surge to 6000% of its original strength."

…………………

"The host has poured ten million years of cultivation into the Mighty Black Gold Hammer, causing its power to surge to 90% of its original strength."

"The Mighty Black Gold Hammer has been infused to its maximum value. Please stop infusing it, host."

Greenie's notification sound flashed through my mind.

Upon hearing the system's reminder, Gu Changqing slowly withdrew his supernatural powers and let out a long breath.

He was incredibly excited and eager to test the power of the Mighty Black Gold Hammer.

So he picked up the powerful black gold hammer in his hand, changed direction, and gently hammered it down onto a gentle mountainside.

"Boom!!!"

This explosion was many times more violent than the last one, and unsurprisingly, it hammered a huge circular black hole into the mountain. This black hole was tens of thousands of times larger than the previous one.

To give an example, if the first black hole was only a hundred meters wide, then this black hole is a full ten thousand meters wide. Keep in mind that this time, no force was used at all; it was just a light tap, yet the power it brought was tens of thousands of times greater than before.

At this moment, this enormous black hole is like a giant Pandora's box. No one knows what is hidden inside, whether it is good or bad. But just looking at the surface, it is dark and deep, unfathomable, and feels extremely terrifying. Those with weak hearts would probably have been scared out of their wits and died long ago.

This time, Gu Changqing caused a much bigger commotion than last time. If everyone was shocked last time, they don't know how to describe it this time.

At this moment, people in the upper and lower realms, thousands of miles away, gaped with disbelief, their faces filled with terror, as if the end of the world had arrived. They were all in a state of deep fear.
