In the middle of the night, everything was silent, when the lights in the streets and alleys of Gu City had been completely extinguished, everything fell into silence, but in the city lord's mansion in the center of Gu City, it was indeed the opposite, a bright light, and the brilliance of the lights shone in this Gu City, symbolizing the core of power.

The mysterious Gu City Lord's Mansion is located in the most core area of Gu City City, and near the City Lord's Mansion, there are the city's wealthy merchants and those nobles who have been inherited for hundreds of years, and they and the sacrifices that symbolize the Gu God form the core power center of the city.

Near the City Lord's Mansion, it is naturally heavily guarded, and the number of patrols is several times more than the number of Gu disciples in the Gu God Temple, these soldiers are armed with spears and swords, patrolling back and forth near the City Lord's Mansion, not to mention people here, even those stray wild cats and wild dogs are impossible to enter.

The city lord of Gu City stood with his hands in his hands, standing in the empty corridor, his brows furrowed tightly, as if he was thinking about something, alone, without saying a word, fell into deep thought.

Gu City is far away from the mainland, there is no need to be afraid of external threats at all, and those countries on the road will not have the slightest interest in this remote city kingdom at all, the only thing to worry about is that those aborigines, after hundreds of years, originally thought that they could wipe out those aborigines early, but those aborigines have resisted tenaciously from generation to generation.

In the current Kojiasi Island, it is rare to see pure-blooded aborigines, most of the aborigines died in the battle with the Gu Master, and some female aborigines, due to intermarriage with some Gu masters, the bloodline on their bodies has long been assimilated by the Gu Master, and their remaining descendants will naturally not consider themselves aborigines.

The so-called Gu Seal is just a curse mark placed on the aborigines of pure blood, once a Gu master intermarries with the aborigines and has any offspring, the Gu Seal will disappear.

Although the number of rebellious aborigines is getting smaller and smaller with the passage of time, this city lord can clearly feel that those stubborn rebel forces that retain the purest aboriginal blood are getting stronger and stronger, and the hatred of hundreds of years seems to ferment, and becomes stronger little by little with time.

At this time, a soldier in armor walked slowly from the corridor, he was the legendary Gu City Knight, responsible for leading all the knights in Gu City, and also responsible for the security of the City Lord's Mansion, and was the most powerful force under the City Lord's Mansion.

He walked up to the City Lord, knelt down on one knee, and said, "Qi Qi City Lord, ten more patrolling soldiers outside the Gu City have been killed, and the death toll of the Gu God Temple has also reached six. ”

"Is the death the same as the previous one?" The city lord said calmly, since a few days ago, two Gu disciples who were on vigil died, this kind of thing has begun to happen one after another, these patrolling soldiers and Gu disciples died extremely tragically, but there is one thing in common, that is, after death, the corpse will faintly show blood-colored marks.

"Well, their corpses all have blood-colored marks, and I have informed the city guards in the city to arrest the murderer all the way, but now...... I don't have a clue yet. The Gu City Knight lowered his head and said.

It's been a few days since the incident, and the death toll is increasing, but there is no clue at all, which is his dereliction of duty.

"Haven't you made any progress?" The city lord asked with a frown.

"Now that the murderer has been arrested in the whole city, please give me a few more days." The Gu City Knight said.

"Don't let go of anyone who can, whoever can, whether it's a murderer or not, will be killed on the spot, and I'd rather kill the wrong person than let it go!" The city lord commanded.

"Yes!" Although the Gu City Knight did not approve of this, he frowned, and finally responded.

"Alas, I'm afraid of this murderer," the city lord sighed, a hint ......of worry on his face.

"Afraid of what?" The Gu City Knight asked suspiciously.

"I'm afraid of this murderer...... Not people! The city lord said.

"Back to the city lord, this murderer is indeed very weird, for the sake of safety, I will send additional knights to guard the city lord's mansion." The ancient city is actually a return.

"Well, remember to send out the Dark Gu Knights as well, the murderer this time is extraordinary, but remember, try not to let them reveal their identities, after all, this force can be regarded as our hole card."

"Yes!" The Gu City Knight said.

The city lord attached so much importance to this attack that he did not hesitate to send out the dark Gu knights who had been secretly cultivated, which made the Gu City knights a little surprised.

The Dark Gu Knights are a mysterious force, secretly trained by the Gu City Knights, and are a hidden force that is only loyal to the City Lord, each Dark Gu Knight must go through a mysterious selection, including family background, talent, mental power, willpower, etc., after passing the selection, they will enter the City Lord's Mansion to start their secret training life.

These dark Gu knights will spend their whole lives in the city lord's mansion, training and life are in the special place opened up by the city lord for them, if there is no special task, they are secretly responsible for protecting the safety of the city lord's mansion, these dark Gu knights, it can be said that they are born for the city lord and die for the city lord.

Of course, the City Lord's Mansion will not treat these Dark Gu Knights badly, after all, they are loyal to the City Lord's direct force, and they will regularly distribute huge amounts of Gu coins every month, and at the same time, the annual Gu City Festival will also release them out of the City Lord's Mansion, so that they can occasionally enjoy the fun of civilians.

At the same time, in order to maintain the loyalty of these Dark Gu Knights, the families of these selected Dark Gu Knights will also receive special preferential treatment from the City Lord's Mansion, whether they are going to the official career or want to trade, they can enjoy generous privileges, so some nobles often let the second son of their family participate in the selection of Dark Gu Knights.

The Gu City knights respectfully retired to the city lord, slowly walked through the corridor, passed through several secret doors, and came to the place where the dark Gu knights lived and trained in their daily lives.

It was a small palace, in the City Lord's Mansion, except for the Dark Gu Knights, only the City Lord and the Gu City Knights knew how to enter these remote palaces, although the palace was not luxurious, but the whole body was mainly black, faintly exuding a strong pressure, when the Gu City Knights walked into this palace, they would feel the invisible coercion surging from all directions.

"This time, the city lord plans to send four dark Gu knights to investigate the recent attack, you can quickly arrange the manpower." The Gu City Knight said to a Dark Gu Knight beside him.

"Okay, then ...... the city lord," the Dark Gu Knight asked.

"The city lord's side should also strengthen the guards, you don't need to train during this time, except for the four dark Gu knights sent out, the rest of the people are all guarding the city lord's mansion day and night in case there is a change." The Gu City Knight commanded.

"Yes!" The Dark Gu Knight said.

"And, remember, try to keep everything secret." The Gu City Knight commanded.

"Please rest assured." The Dark Gu Knight beside him replied.

In the cold middle of the night, a layer of dark clouds gradually drifted over the City Lord's Mansion, shrouding the faint moonlight......
