The hall in the core of Silent City was filled with whispers of discussion for a while, and it wasn't until Felina coughed lightly that the hall fell silent.

"Yso, huh?"

Filina looked at Isu and tried to make her voice less eager: "Is there any limit to your ability?" ”

"There is a limit, I can only control five cards at the same time now," Isu nodded, seeing the disappointed expression on Phirina's face, she hurriedly added: "Of course, if my strength increases again, I will be able to control more cards." ”

"Ascension?" Filina frowned slightly: "What resources do you need?" ”

"This ......" Isu hesitated a little, but Yu Guang saw that El was constantly glaring at him, and hurriedly said: "I don't need other resources, as long as I can get more and more powerful cards, my strength can be improved!" ”

"Get more cards?"

"That's right! As long as you kill an enemy, you have a certain chance to get a card, which may be the enemy itself, or it may be a piece of equipment or a certain skill of the enemy, etc. ”

Isu added again, only to see Firina turn to look at Al, "So, you're here to borrow someone, right?" ”

"Hehe, the eldest sister is really resourceful and wise!" Al didn't hesitate to say a series of compliments, and after seeing Filina's expression improve slightly, he spoke: "Isn't this also to reduce the loss of the Shadow Blade, anyway, we never lack enemies, do we?" ”

Yi Su suddenly understood, it must be that Silent City needs a batch of high-end cannon fodder, but he is reluctant to consume his elite strength, so he called him over.

However, Isu was not disgusted in his heart, since Silent City needed a group of powerful cannon fodder, then while using him, he must be cultivated, and in comparison, he could gain much more benefits than he lost.

Izu was thinking about his own affairs, and on the side, a group of bigwigs in Silent City also quarreled, and the questions were nothing more than two, one was about the reliability of Izu, and the other was about who to cultivate and how to cultivate Isu.

Unbeknownst to Izu, Isu was standing nearby, but when the higher-ups of Silent City began to argue, Al unleashed a soundproof barrier in the council hall to isolate Azu.

After more than ten minutes, the soundproofing barrier disappeared, and Firina strode up to Ysu: "Ys, Isu, I think you have already guessed what you are going to do next, but due to the previous precedent of your companion's betrayal of Silent City, although El is willing to believe you, it does not mean that all of us believe in you. ”

"So, I need to prove my loyalty to the Silent City?"

"No," Filina shook her head, "you just need to sign a contract with me. ”

After speaking, Filina summoned a silver-gray metal plate: "This is a contract created with the help of Aka's divine power, the contents are all in it, you can use your spirit to perceive it, if you agree, you only need to leave your life breath on the contract." ”

"If I refuse ......"

"Then get out of here, as if nothing had happened."

Firina bites the word "here" very hard, presumably referring to more than just the Great Hall or the core of Silent City.

"Understood."

Isu nodded, pressed her palm on the contract, and felt it quietly, and after a few minutes, Isu raised her head: "I have no objection to this contract, but how can I leave the breath of life on it?" Dripping blood? ”

……

A week later, Maid II left the Silent City escorted by a demon army squad to visit Solitary City, and just after Maid II left, another team left the same elevator and headed north.

Even after leaving the black fall, Isu still has a wonderful feeling, constantly touching the card bag on his waist along the way, and there is always a feeling of dreaming.

In just one week, Silent City has provided Yth with nearly 10,000 death row prisoners and prisoners of war, and if it weren't for the fact that he could get cards from a minion of creatures, Isu would have suffered from mental illness if he hadn't become a murderous pervert.

However, at the beginning, there was still a hurdle in Yisu's heart, a little guilt, although he didn't do it himself, although most of the monsters killed were twisted snow elves and underground trolls, but no matter what, this is also a living life!

But later, Isu gradually "got used to", or rather, became numb, just like a veteran who has fought in the field for most of his life, and the life of a soldier has become a string of numbers in their eyes.

And with that came the excitement of that thick stack of cards.

During the week, the forces of the Silent City launched a massive sweep war in the Black Lords under the pretext of protecting the Emperor, and by the time Isu left the Black Landings, the Silent City had eliminated a total of twenty-three hostile snow elf tribes, three underground troll tribes hostile to the Silent City, and a wandering giant expelled from the camp.

In addition to the underground battle, Silent City also sent several troops to the surface to clear the bandit camps around the various dwarven elevators controlled by Silent City, and Filina also continued her dragon slaying business, oh, it should be said that it is a dragon catching business now, in just one week, she helped Ysu capture three dragons, including a dragon that has recovered the legendary realm.

And all of this has become this stack of cards in Isu's hand.

First of all, the two cards of [Loyal Knight] and [Armed Emblem], these two cards that have followed Ysu for the longest time, and of course the first cards to be promoted, after consuming dozens of dark steel cards, as well as two red bronze cards, these two cards have been promoted to the red bronze rank, and then Isu spent twelve low-level red bronze cards to upgrade [Loyal Knight] to six stars of red bronze.

[Guardian Knight (Willy), Creature/Human, Bronze Six, 50/1/10, Effect: Summons a level 51 Guardian Knight with the Guardian Ability Defender to fight for you. Card Characteristics: Loyalty, the Knight will protect you as the supreme creed and obey any orders you make. Card Only: After Willy's death, the card characteristics disappear. 】

【Guard!】 My Destiny! 】

[Guardian Ankh, Artifact, Red Bronze, 30/0/0/1, Effect (Activation): Consumes 20 mana crystals to bless the Guardian set for the specified target (knight set, sword and shield limited, the effect is equivalent to the epic demon suit). 】

【Sanctuary of the Templars】

As in Darksteel, the two cards still have a special card association.

[Card Association (Guardian Knight/Guardian Ankh): Guardian Barrier: When the Guardian Ankh is blessed with an arm for the Guardian Knight, an additional 10 mana crystals will be consumed, and the blessed weapon will be enchanted by the Guardian. 】
