Very soon, everyone followed the City Lord to a watchtower.
This watchtower had restrictions securing it, and usually, soldiers patrolling would not dare to come near, as they knew it housed the forbidden weapon, the God Slaying Cannon.
Now, with the City Lord leading them to this watchtower, he waived to lift the restrictions. Instantly, a fierce-looking cannon, crafted from an unknown material, appearing to be both metal and jade, stood over two meters high and over ten meters long, revealed itself before them.
As Mu Jinyu saw this God Slaying Cannon, his eyelid twitched involuntarily, sensing a vague but immense threat. If he stood before the cannon unguarded, he estimated he'd be severely injured by a single blast.
"Everyone, please lend a hand!"
The City Lord, after lifting the restrictions, stood behind the God Slaying Cannon, began adjusting the trajectory, targeting the rear of the beast tide, then turned to speak to everyone present.
"Alright!"
"Let's do our best together!"
Over a hundred cultivators, upon hearing the City Lord's words, agreed without hesitation.
Anyway, they didn't have to face the beast tide head-on; they could just stand atop the city walls and channel some True Yuan. There was no life threat, so even cultivators from other nations passing through Demon Slaying City were happy to help.
The City Lord nodded appreciatively, then raised his hand to the God Slaying Cannon, operated the Profound Skill, and infused abundant True Essence into the cannon continuously.
"Buzz!!"
After a short while, the God Slaying Cannon slightly trembled, then everyone observing with Divine Sense could see the cannon muzzle accumulating scintillating starlight, evidently stockpiling terrifying energy.
"Thank you all!"
After just a few instants, the City Lord's complexion turned pale like paper, almost completely drained of True Yuan. He quickly withdrew his hand and stepped back, turning to the group.
"Everyone, please proceed!"
The native cultivators of Demon Slaying City moved forward without any hesitation, stepping up to stand beside the God Slaying Cannon, then raised their hands to press onto the cannon barrel, channeling True Yuan into it!
Next, cultivators from the Wu Kingdom followed suit, also injecting True Yuan into the cannon.
Then, cultivators from other nations, though initially startled by how drained everyone seemed, felt compelled to join in, thinking that if Demon Slaying City fell, their own fate would not be much better. Thus, with gritted teeth, they advanced and injected True Yuan into it.
Mu Jinyu, Wen Rou, and Jian Ruyan also stepped forward, raising their hands to press onto the cannon barrel, channeling True Yuan into it.
In a matter of moments, the two women, despite being in the Divinity Transformation Realm, exhausted their True Yuan and quickly withdrew, feeling overwhelmed.
However, Mu Jinyu, thanks to the existence of the mystical little tree in his Sea of Consciousness, always had abundant True Yuan, seemingly inexhaustible.
Even though he felt much of his True Yuan being siphoned, he still had reserves left.
At this moment, the City Lord had also somewhat recovered by absorbing Heaven and Earth Vital Energy. Upon noticing Mu Jinyu still persevering in channeling True Yuan, a trace of surprise flashed in his eyes.
'This young man has exceptionally abundant True Yuan!' he inwardly marveled, then stepped forward and said to Mu Jinyu, "Young man, that's enough. You can step down now."
"Alright." Mu Jinyu also didn't want to stand out too much or let others notice the peculiarity of his True Yuan, so upon hearing this, he retreated to Wen Rou and the two ladies.
The gathered cultivators now looked pale, desperately absorbing Heaven and Earth Vital Energy to replenish their drained True Yuan, none really noticing Mu Jinyu's remarkable endurance or remaining strength.
The City Lord also paid no further attention to Mu Jinyu. Once he observed the God Slaying Cannon having accumulated sufficient energy, he fine-tuned the trajectory slightly, then gathered his focus and forcefully slapped the cannon body!
Like triggering some mechanism!
"Boom!"
A thunderous roar, like the collapse of Mount Tai, erupted. Everyone present, despite being at least in the Divinity Transformation Realm, felt their eardrums ache, seeing stars, barely avoiding being stunned.
Fortunately, the city walls had powerful restrictions in place, preventing the tremendous noise from reaching Demon Slaying City, otherwise tens of thousands of citizens might have perished on the spot!
Amidst them, the only one who maintained clarity, Mu Jinyu, saw a dazzling ray like the blazing sun burst forth from the God Slaying Cannon's muzzle, shooting straight towards the rear of the surging beast tide!
The Wu Kingdom's Heaven's Pride, Wu Zhiming, seemed to have some tacit understanding with the City Lord, as he immediately ceased his golden domain from reaping the lives of numerous ferocious beasts, leaping back tens of miles.
"Rumble!!!"
At this moment, that radiant, sun-like God-Annihilation Energy Cannon hit directly at the densely packed beast tide!
"Wow!"
The blinding white light instantly erupted, causing an almost stinging sensation in Mu Jinyu's eyes, as if tears were about to fall.
None dared to stare directly at the terrifying strike of the God Slaying Cannon, yet still only perceived a field of white light before them, unable to see anything.
Time ticked by gradually.
About three minutes seemed to pass.
Mu Jinyu felt that the stark white began to fade away.
As his eyesight returned to normal and the white light dispersed, he could now clearly see the scene ahead.
But as he clearly saw the scene in front, his expression darkened slightly.
In the dense murmur of the beast tide, indeed, tens of thousands of ferocious beasts had been blasted away at the rear. All around was a mud of red, a blood ground formed by the beasts' flesh and blood.
However, according to the City Lord's prediction, after firing the God Slaying Cannon, no matter how many ferocious and demon beasts there were, they should have been scared back, never daring to assault Demon Slaying City again!
But now, countless ferocious beasts still remained at the rear, eyes filled with endless fear, yet still chose to charge forward tirelessly!
As if something even more terrifying than the God Slaying Cannon was behind them!
"What's going on?"
Mu Jinyu heard the City Lord muttering to himself in shock and doubt.
Evidently, the other party had not anticipated this outcome.
"Fire another shot!"
Mu Jinyu turned to remind the City Lord.
"No can do." The City Lord turned to glance at Mu Jinyu in surprise, seemingly not expecting him to recover so quickly, then shook his head and explained: "The God Slaying Cannon's power isn't just due to our True Yuan, but also the energy it accumulated over several years!"
Hearing the City Lord's words, Mu Jinyu's heart sank, understanding that the City Lord meant the God Slaying Cannon's might was primarily due to its own energy accumulated over the years, with everyone's True Yuan merely stimulating it to release that energy wave.
And currently, the God Slaying Cannon had already unleashed its invincible strike, and no amount of True Yuan from everyone would replicate such a devastating blow now!
At least several years of recovery are needed.
Sure enough, the City Lord continued explaining:
"Moreover, even if we had a thousand Fanxu Realm cultivators here together infusing True Yuan into the God Slaying Cannon, we couldn't activate it now. This Spiritual Treasure has various restrictions and can only be activated once every six months! Otherwise, the core crystal stone would be directly destroyed!"
Saying so, the City Lord sighed deeply again, and added: "Besides, the beast tide is nearly arriving at the city walls now, leaving us no time to activate another shot of the God Slaying Cannon!"
Upon hearing these words, Mu Jinyu abruptly raised his head, just to see that after Wu Zhiming's withdrawal earlier, without his obstruction now, tens of thousands of ferocious beasts at the forefront were already ten miles away from Demon Slaying City, about to arrive.
The beasts were about to reach the city gates!
