Online Games: From Professional Gold Farmer to Night King

"Lord City Lord..."

A giant blade was stuck in Jian Jiu's chest; it was the same greatsword that the Blade Demon King held.

As the greatsword pierced through, Jian Jiu's last bit of life was wiped out, and he slid through the air, crashing heavily to the ground.

"Sword Nine!!"

These ten people were trained by Kentaro from childhood, and he taught them everything he knew. It wouldn't be an exaggeration to call them his adopted sons.

Now, nine of the ten adopted sons have died, and only Jianyi is still struggling to hold on, but he won't last much longer.

These ten guards were indeed powerful, but they were still inferior to ordinary demon kings, let alone demon kings like the Blade Demon King and the Thorn Demon King, whose strength had increased dramatically.

The fight lasted only a dozen minutes, and with the help of the Demon King, nine of them were killed.

Although the Ten Royal Guards suffered heavy casualties, they were not entirely useless. Three of the eight Demon Kings were killed by Kentaro, including the Iron Demon King and the Thorn Demon King.

The ten guards joined forces to kill two of them, both of whom were newly promoted demon kings.

Currently, only three of the eight Demon Kings remain, and all of them are injured. On the other hand, Kentaro still has 90% health and his strength has not been greatly diminished. It is only a matter of time before he defeats the remaining three Demon Kings.

As for the demon army below, even without me, with tens of millions of players and hundreds of thousands of guards, it would be enough to wipe them out!

In this battle, as long as the remaining three Demon Kings are killed, the threat of Four Seas City will be neutralized.

"We must finish this quickly! I can already sense the seal starting to weaken; we must hurry back and reinforce it! In that case..."

Kentaro gripped his katana tightly with both hands, slowly raising it until it was above his head, as if he and the katana had become one.

"Man and sword as one!"

"Buzz~~"

The katana emitted a crisp crackling sound, and a sharp sword aura descended from the sky, instantly enveloping Kentaro.

"Return to the Sea with a Single Blade! Slash!"

"Whoosh~~~!"

A terrifying slash descended from the sky, its range reaching a terrifying kilometer!

"Demonic transformation!!! Let's fight him! For the demon race!!"

"For the Demon Race!!!!"

The three demon kings' auras surged, their bodies flashing with black and red light, as they charged straight at the terrifying slash.

"boom!!!"

...

A deafening explosion resounded, sending a terrifying shockwave soaring into the sky and scattering the clouds for miles around.

After the explosion, the three demon kings had vanished without a trace, not even their bodies remained.

The demons and players below were instantly cleared of more than one or two thousand meters due to the explosion.

Based on density calculations, at least 100,000 players, guards, and demons were wiped out by the explosion.

"Hmph! With just eight demon kings, they dare to invade my Four Seas City? They're courting death! Issue the order..."

"boom!"

Just as Kentaro was about to order a full-scale attack to completely annihilate the demon army, a violent crashing sound came from behind.

As the sound of the impact rang out, the entire Sihai City fell into a deathly silence.

Demons, players, guards, and even Kentaro—everyone turned to look into the city.

"No...this is impossible...the seal is extremely strong. Even if I'm away from the city for a short time, it would only loosen slightly at most, it could never break! What on earth is going on?!"

"Whoosh~"

Kentaro transformed into a streak of light and flew rapidly towards the sky above the city lord's mansion.

At this time, the city lord's mansion had sunk two or three meters, and was filled with cracks; some of the buildings had already collapsed.

And from the cracks, extremely dense black energy was billowing out.

As time went by, the black aura grew thicker and thicker until it formed a dense black fog that enveloped the entire city lord's mansion.

"Sealing Spell! Seal!!"

Kentaro formed a hand seal, and a huge "seal" character fell, crashing into the black mist.

"Bang!"

The black mist collided with the sealing spell, and the originally golden sealing spell exploded instantly.

Seeing the sealing spell that had become useless, Kentaro felt as if he had fallen into an ice cave. The hairs on his body stood on end, and his body trembled slightly uncontrollably.

Demon Emperor!

The power of those two words was immense. Although he looked down on the Demon King and could easily kill him, the Demon Emperor's strength far surpassed that of the Demon King!

Just as the current city lord is weaker than the Demon King, he is also weaker than the Demon Emperor, a fact he is well aware of.

After ten thousand years of peace, the strength of this generation is no longer comparable to that of their ancestors.

In other words, even if he reaches the strength of his ancestor, so what? His ancestor died from severe injuries after sealing the Demon Queen, so what about him? What will happen to him?

Although the previous battles did not severely damage their strength, they were no longer at their peak.

Under what circumstances could he possibly be able to fight against a Demon Emperor who had absorbed the demonic energy of countless demons and eight Demon Kings?

"Everyone! Evacuate Sihai City immediately!!!"

Kentaro roared, and everyone in the entire Four Seas City could hear it.

Even the most clueless player would understand what had happened at this point.

The Demon Emperor is about to break free from his seal!!!

After shouting those words, Kentaro ignored everyone else and took out a token from his pocket.

He bit his finger, and a drop of blood fell onto the token.

"Buzz~~~!!"

The token began to tremble violently upon contact with blood, and the token, which was originally as hard as cast iron, began to emit bursts of blue fluorescence.

"City-protecting formation! Activate!!!"

"Sizzle~~"

A sound similar to a laser beam rang out, and a cyan light curtain rose from the city wall of Sihai City.

The light curtain gradually extended upwards, slowly enveloping the entire Sihai City.

The city of Sihai is vast, with its walls stretching for over a hundred miles on one side! Yet this token can activate such a powerful city-protecting array, demonstrating its extraordinary nature.

As the protective array gradually rose, Kentaro's heart finally calmed down a little.

"This protective formation was left by our ancestors to prevent the Demon Emperor from breaking free and his descendants from being too weak to reseal him. Within this formation, my strength can be increased by 50%, while the Demon Emperor's strength will be suppressed by 20%. With this disparity, I might very well be able to fight him!"

"It's just a pity..."

Kentaro glanced at the distance and sighed. "It's a pity that only one of the Ten Guards is left. If they were all alive, setting up the Ten Directions Demon Slayer Formation would increase the chances of sealing the Demon Emperor by at least 1%!"

"Now... we have no choice but to fight!"
