Once he reached the territory of the Silver Winged Family, Xiao Yan activated the void-form of his Shadow Devil, he didn't want them to flee by fear.
He located Sikong Yi in the main hall, on his throne with three beautiful girls massaging him.
{These girls are not from the Silver Winged Family, they are slaves with better conditions since they have nice bodies, I shouldn't kill them}
Back in his human form, he took a sword to quickly kill the Patriarch, stored his corpse in his storage ring, then knocked the three girls with the back of his hand.
{Well, sorry but the last thing I need right now is someone screaming}
It was then the turn of the guards who were also in the main hall, all of them being Gold Ranks.
That didn't change anything, they still died without being able to alarm the others.
Spreading his senses to the whole Palace, he then looked for the other two Elders.
They were both in their own room, having fun with some girls.
This time he first knocked the girls, then kill the old men and also kept their bodies.
{Now I have the bodies of one Legend Rank and ten Black Gold Ranks, just enough to use that technique. I'll try it tonight or tomorrow}
Next, he killed all of the people inside of the Palace who weren't slaves.
He didn't need their bodies, he just took their storage rings if they had one.
When he finished, he went to the treasury to put everything inside of his storage rings and did the same for their library.
{Now it's time to free the slaves of the mine}
He transformed back into the Shadow Devil to activate the void-form before going there.
Noticing a tower near of the mine, he knew that he would need to sneak inside of it to kill three people.
They were inscriptionists who used a technique called "Blood Imprint" on the slaves.
It was a technique preventing the slaves from being more than one kilometer from them, else they would die.
Not only that, the person would also feel great pain even if he stayed inside of that range.
There were only two methods to erase that Blood Imprint.
The first one would be for the victim to reach the Gold Rank, and the second one would be to kill the inscriptionist who casted it.
They also knew of it, so they were well protected and had a lot of inscription patterns ready to be activated.
Xiao Yan easily sneaked behind them, killing the three before they had the time to activate their inscriptions.
Back in his human form, he took their storage rings and exited the tower.
As the slaves noticed that their blood imprints were gone, they stopped working and were now looking at the guards, waiting for something.
Xiao Yan gave them the signal they needed by starting to kill the guards with his sword, he only stopped a little to take the storage ring if the guard had one, else he would run straight to the next one.
The slaves let out a loud battle cry, then they ran to take the weapons of the nearest corpses and also started to kill the guards.
The guards at the mine were generally not used to fight, they couldn't defend themselves against these people who wanted to fight for their freedom.
Soon, it was a one sided battle, even if the hundreds of slaves were against thousands, they managed to overwhelm them as they had much more fighting spirit. There was also Xiao Yan, who by himself killed more than what the slaves killed altogether, and he also targeted the stronger guards first.
In nearly an hour, the territory of the Silver Winged Family was filled with corpses and the survivors of the Family started to flee in the direction of the Trading Town.
Witnessing that, Xiao Yan flew in the sky a hundred meters ahead of them.
{I won't let a single one of you alive}
He then went down and continued his killing spree, not sparring anyone. The slaves were also merciless, as they were tortured everyday since months or even years by this family. They wanted to make them pay for what they did to them, they wanted their revenge.
After half an hour, all the members of the Silver Winged Family were dead.
The strongest family of the Abyss Prison Realm, with a history of thousands years, fell in less than two hours.
Xiao Yan didn't want to celebrate with the freed slaves and instead went to the town to regroup with Duan Jian's family.
While flying, he checked all of the storage rings he just took, nearly three hundred.
Most of them contained food and he now had tens of thousand bags of food.
As for Blood Crystals, there was thousands jars of one thousand, but they were all unrefined.
What surprised him was that he found more than two hundred Stones of Light. He needed twenty three if he wanted to go back to Glory City by using the array he used to come here the first time.
{In the story they took weeks before getting fifty ready for Nie Li, that means they already had the Stones of Light since the beginning and were just gaining some time to observe him}
Aside from that, there was also a lot of equipments, materials and any other things you would find in a treasury, but nothing was out of ordinary.
He planned to let his parents divide it between his own family and the betrothal gift to the Snow Wind Family.
When he finally arrived at the town, he saw Duan Jian and his parents waiting for him at the entrance.
They already took a bath and were now wearing clean clothes.
Xiao Yan took them to an inn, put some soundproof inscriptions around the room and started to talk to Duan Jian, "Nobody can hear our conversation now. I wanted to ask, are you sure you want to serve me?"
