He watched the great dragon in the water sphere, still alive.
Luke frowned slightly, casting his strongest Transfiguration spell with his wand.
The water sphere rapidly transformed, becoming a giant python even larger than Smaug, tightly coiling around him, eventually turning into massive chains that firmly bound the great dragon.
After completing all this, Luke couldn't help but gasp for breath, his face slightly pale.
Performing Transfiguration on such a colossal creature was too much for him at his current level; if not for Gandalf's Ring of Fire, he wouldn't have dared to try.
"Are you alright?" Gandalf asked with concern.
Luke shook his head.
"I'm fine. The most important thing now is to deal with this great dragon!"
The great dragon was now bound by massive chains, its limbs and mouth firmly restrained, temporarily losing its ability to move.
They had to seize this opportunity to deal with him as quickly as possible.
Otherwise, if the great dragon recovered and broke free, he would be difficult to handle.
The two quickly approached the great dragon. With his mouth bound by chains, they didn't have to worry about the great dragon suddenly spewing dragon fire for the time being.
Gandalf stood on the dragon's back, forcefully pulling out foe-hammer, which was embedded in his back.
Luke also came to the great dragon's injured wing, gripping the divine spear aeglos with both hands, using all his might to pull it out. A hot, lava-like blood flowed from the wound.
The great dragon immediately let out a painful groan.
Luke waved his wand, making the great dragon flip over, exposing his chest upwards.
The two looked at the missing scale on the great dragon's chest, which was now covered with molten black arrow.
The material of the black arrow was extremely hard, and now covering the gap, its defensive power was no less than the original dragon scales.
It could be said that the great dragon now had no weaknesses.
However, this was only true for others.
Luke gently tapped the black iron on the gap with his wand, and the black iron slowly deformed, turning into a huge iron nail that pierced into the flesh.
The great dragon, feeling his life threatened, struggled violently, a look of terror in his eyes.
"No, don't kill me! I surrender! As long as you let me go, I promise not to seek revenge on you, and I can even give you all my treasures!"
Smaug, whose mouth was sealed, conveyed a plea for mercy through mental power.
Gandalf saw Luke stop his actions and, thinking he had been swayed by the great dragon, quickly reminded him, "Luke, don't believe the great dragon's words. Great dragons are very cunning, and their words are their magic, very skilled at sowing discord and bewitching people!"
Seeing Gandalf's worried expression, Luke smiled and shook his head.
"Gandalf, don't worry, I won't be easily swayed by the great dragon."
"It's just that I thought of a better way than killing the great dragon, so I want to try it."
Gandalf was still uneasy; in his opinion, such an evil creature as a great dragon should be thoroughly killed.
However, since the great dragon was restrained by Luke, how to deal with him was up to Luke.
"Luke, what's your plan?"
"I have a contract magic here that requires both parties to willingly sign it, and with the witness of a third party, it can form an absolute binding force, ensuring that no one can violate the contract."
Luke explained.
"I want to ask you, Gandalf, to be the witness, and then Smaug and I will sign a contract, making him serve me."
Hearing Luke's words, Gandalf frowned deeply, his face filled with worry.
"Will it really work?"
"Let's give it a try!" Luke said, shrugging, but his face was filled with confidence.
As he spoke, he turned to look at the great dragon, his eyes cold.
"Smaug, you heard him. Speak, are you willing to swear an oath to me and submit to me?"
"If not, I will send you to your death right now!"
The divine spear aeglos in his hand emitted a sharp glint, pressing directly against the great dragon's forehead, causing a faint stinging sensation.
Hearing that there was a chance to live, the great dragon Smaug was overjoyed, a hint of cunning flashing in his eyes, and he immediately nodded.
"Willing! I am willing!"
Seeing him agree so quickly, Luke sneered inwardly.
Anyway, he was just asking, regardless of whether Smaug was sincere or not.
Once the contract was completed, it would be useless for the other party to regret it.
So Luke cast a silencing spell on himself and Gandalf, and also blurred the image, then handed the unbreakable Unbreakable Vow to Gandalf.
The more Gandalf listened, the brighter his eyes became, and his originally worried expression gradually softened,
his face filled with surprise and admiration for Luke.
"Luke, you've given me another surprise!"
Outside the silencing spell, Smaug watched the two talking but couldn't hear any information, and the change in Gandalf's attitude made him feel a vague sense of unease.
Not long after, Luke removed the silencing spell.
"Smaug, from now on, you will do as I say, without the slightest resistance."
"Otherwise, if there's even a moment of hesitation, I will let that iron nail in your chest continue to grow inward until it pierces your heart and kills you!"
"Did you hear me?" Luke's voice became stern and cold.
Smaug grew increasingly uneasy, but seeing the undisguised killing intent in Luke's eyes, and the stirring iron nail in his chest, he quickly nodded.
"I heard you, I am willing to obey you!"
Time was pressing, so Luke didn't waste any more words with Smaug. He directly placed one hand on the great dragon's forehead and began to chant a spell.
And Gandalf, as the witness, drew out the wand Luke had made for him earlier, placing it on Luke's hand where it made contact with the great dragon.
"Great dragon Smaug, are you willing to submit to me and be commanded by me from now on?" Luke asked.
Smaug could already feel an invisible magic shrouding him and Luke. Once he agreed, that magic would descend upon him, forming an unbreakable soul bond.
Understanding the situation, Smaug instantly felt bad!
He had originally been very confident that even if he signed some magic contract, he was confident he could break free. Then, when Luke was unprepared,
he would take harsh revenge to repay the humiliation Luke had brought upon him.
But he never expected that there was such a contract magic in this world that he had never heard of, which directly bound the soul!
Without giving him time to hesitate, the giant iron nail in his chest rapidly grew, piercing into his flesh and quickly heading towards his heart,
Smaug instantly felt his soul leave his body. He clearly perceived that the tip of the iron nail had already touched his heart and was about to pierce through it in the next second.
"I agree! I agree!!!"
Smaug shouted in terror.
As soon as his voice fell, the tip of Gandalf's wand shot out a thin, dazzling tongue of flame, like a red-hot metal thread, coiling around Luke's hand and the great dragon's neck.
Then it merged into them, turning into a golden-red pattern.
"Great dragon Smaug, from this moment on, are you willing to never betray me, and never harm me, until the end of your life?"
This time, without waiting for Luke's threat, Smaug quickly replied, "I am willing!"
The tip of the wand shot out another tongue of flame, adding a tattoo to Luke's right hand and Smaug's neck.
"Great dragon Smaug, from this moment on, are you willing to always obey my commands, and never defy them at any time?"
"I am willing!"
With Gandalf, the wise man, present to supplement and remind him,
Luke made more than a dozen vows, covering all aspects to ensure that his vows could not be exploited or leave room for linguistic traps.
Finally, golden-red patterns were left on Luke's arm, looking very mysterious and cool.
Having completed the vows, Luke waved his hand and released the chains on Smaug's body.
The great dragon Smaug, bound by the vows, had now resigned himself to his fate.
He didn't even dare to harbor a trace of malice towards Luke in his heart.
If he showed even a little, the golden-red patterns on his neck would come alive, turning into red-hot metal threads that would constantly tighten, trying to strangle him to death, and his soul would also become excruciatingly painful, comparable to the power of Crucio.
Moreover, if he dared to retaliate, he would die instantly before he could even lay a hand on Luke!
"Master—" Smaug lowered his head, calling out humbly.
