"I will keep my promise, honorable Lord Konstantin." When the contract was signed, Leonid did not understand what it meant to make a contract with the "devil", and when he deeply understood the consequences of breaking the contract, there was no turning back.

"It's not enough, Leonid my dear friend, according to the contract we signed six years ago, I promised to bring back your dead lover, and you, and Natalia, are going to convince those closest to me to work for me, and now Natalia has brought me her favorite sister, but where is your father?"

Konstantin's questioning made Leonid have no time to think about it, so he could only make a promise: "My father will be here soon, Lord Konstantin, Isabel is a good bait, and we can catch big fish with her." ”

"That sounds reasonable, I hope the fish will take the bait sooner, my friend, today is the end date of the contract, if you can't complete the contract by the end of today, I will have the right to dispose of your father as I like, and if he refuses to serve me, I will have to take his soul......" Konstantin's pretended indifference contained a cold threat.

Leonid took a deep breath, plucked up his courage to raise his head and ask the devil: "Dear Lord Constantine, I don't understand why you are particularly interested in my father. ”

"Hehe, your father can teach such an excellent son, and he must also be an extremely talented machine warlock, I need such a talent to create a weapon for me." Konstantin replied with a chuckle.

"I've created quite a few crafts for you over the years, isn't that enough?" Leonid asked confusedly.

"Far from enough!" Konstantin replied sharply. The chain cloak on his body trembled, showing that he could no longer remain at peace, chagrin, resentment, and a trace of unconcealable fear flashed in his red eyes, "I have been forced to hide in the Shadow Realm all these years, but my heart will always belong to the Bato Hell, one day I will return to the Iron Plains, wash away the shame I suffered in the blood station thirty years ago, and regain the appreciation of the great Nine Helllord Asmodeus, for this I must have a sufficiently strong and absolutely loyal Constructed Legion, You alone can't accomplish this mission. ”

"I see, Master Konstantin." Leonid was shocked by the devil's ambitions, but did not dare to question it to his face.

"Go, my friend, and better not leave regrets on this long night." Konstantin relaxed and curled up in the wide throne, his deep voice revealing a hint of tiredness.

Leonid bowed deeply to him and grabbed the hand of the secret puppet girl beside him to activate the teleportation array. A light rose from the altar, and the figures of the two men slowly disappeared. At the same time, in the center of the hall on the third floor below, an altar of the same shape rose with light, from which the figures of Leonid and Natalia emerged.

For some reason, Konstantin hated stairs very much, and when he commissioned Leonid to build this Hidden Demon Tower for him, he emphasized that no stairs should be set up in the tower, and from the first floor to the fourth floor, up and down were all teleported.

Leaving the devil's room, Leonid breathed a sigh of relief and walked down the altar with a heavy heart. Natalia followed behind him, as silent as ever.

Leonid suddenly stopped and looked back at the pretty face of the Iron Lover without a trace of expression: "Natalia, do you regret it?" ”

"Regret what?" Natalia's eyes were blank.

"It's all there." Leonid said faintly.

Natalia was silent for a long time before speaking, "I don't know, my dear, since the day my soul fused with this metal shell, I have lost a lot of things, including most of my emotions and memories...... I don't know what regret is, I just hate myself more and more, especially after meeting Isabel. ”

"Me too, poor Natalia, but there's no way back." Leonid sighed.

"I don't understand these complicated emotions, I just know that I love you, and I will be with you no matter what, even if it is to face death together." Natalia murmured softly.

"With your words, I die without regrets." The Mithril Warlock squeezed his lover's hand hard, his eyes rekindled, "Let's go, we need to get ready to meet my father and his two nosy friends." ”

"Are you sure they still have a chance to make it to the third floor?" The secret puppet girl asked suspiciously.

"Dear Natalia, you asked a stupid question," Leonid smiled bitterly, mixed emotions of pride and sadness intertwined in his eyes, "The weapons downstairs are certainly powerful, but how can they alone stop my father, a great tricker? In today's battle, our father and son will finally win or lose! ”

……

On the first floor of the Hidden Demon Tower, the closed door is made of steel, and the lock installed by Leonid himself is not only sturdy but also very complicated, unless the correct password is entered, not only will the iron door not be opened, but those who try to open the door will also trigger a hidden mechanism, which will be instantly dissolved into dust by the dissociation ray. At this moment, however, these intricately constructed locks and mechanisms are all useless to their creator's father.

Quasi-legendary mechanism warlock Matway Wittgenstein walked to the door with the Battle of Destruction in his hand and observed it for a few seconds, then raised his staff and touched the closed iron door.

The black steel long stick engraved with runes in the old man's hand looked inconspicuous, but it was the nemesis of all the machines and structures in the world, and the moment the head of the staff touched the door, it inspired a golden light, and the 6-ring structure dismantling technique was quietly released.

There was a series of cracking sounds behind the large iron door, and the intricate metal structures that made up the locks and mechanisms disintegrated under the influence of magic, and the closed door opened, and a scorching air poured out of the dimly lit hall with a strong sulfurous smell.

"This is the breath of purgatory...... Roland reminded the mage beside him in a low voice, "It seems that our devil friend is ready to welcome the guests." ”

"Those devils better be polite to us, or I won't mind banishing them back to the Nine Prisons." The corners of Nikita's lips curled with confidence, and she expertly cast a series of spell casting gestures, the magic turning into green and yellow sparks around her, like a gust of wind rolling up colorful confetti and whirling in a soft whistling.

Roland could see that she was blessing a 6-ring spell called "Arcane Surge", and all other spells cast by Nikita would automatically receive an instantaneous effect while the Arcane Surge lasted.

As soon as Nikita finished casting the spell, Matvey couldn't wait to walk through the gates of the tower. Roland hurriedly followed, and his vision, strengthened by the high-level golden dragon bloodline, quickly adapted to the dark environment in the tower, but he did not notice a trace of life.
