Although the body defense of Diamond Earth Gold surpassed that of the Martial Emperor, his strength and speed, as well as the upper limit of the energy contained in his body, were all at the level of a ninth-level Martial Sect.

Before the Demon Sword was repaired, Lin Yun would be able to barely tie with the ninth-level Martial Sect in the second form of the Demon God Core Crystal.

And now that the Demon Sword has been repaired, its power has been greatly improved compared to before, and after Lin Yun opened the second form of the Demon God Nuclear Crystal, there were almost no opponents under the Martial Emperor Realm.

Therefore, it is normal for this diamond ground gold to be beaten by Lin Yun. Fortunately, the decapitation sword in his hand was also a heaven-level treasure weapon, otherwise it would have been cut off directly by the Demon Sword.

"I didn't expect you to be so powerful, it seems that I underestimated you too much." After Diamond Dijin said this, the three tadpole-shaped black curse marks on his neck suddenly lit up with red light.

And then, the tadpole-like marks split and spread from his neck to the skin around him, crawling all over the left half of his cheek, then over the high bridge of his nose, towards the right cheek, and finally covering every inch of his skin.

But that's not all.

The black spell marks swelled rapidly, encroaching on normal skin, and finally all the black spell marks were tightly connected together, turning blood red.

A bloodthirsty and violent aura was released from the body of Diamond Dijin. His hair instantly grew longer and blood-red.

A pair of bat-like black wings grew from his back and spread out for more than ten meters.

Lin Yun could clearly perceive that the aura of diamond ground gold had become several times stronger than before. Before, his aura was only at the level of a ninth-level Martial Sect, but now he has completely reached the level of a Martial Emperor!

The diamond ground gold spread its wings and flew off the ground in an instant. He hung in the air and looked at Lin Yun condescendingly: "Now, I won't lose to you again." ”

Lin Yun glanced at the diamond ground gold with disdain, and said with a cold face: "Borrowing the power of others, but there will be a price." ”

Diamond Dijin's expression froze instantly: "You...... What did you say? How would you know...... Am I borrowing the power of others? ”

"If I'm not mistaken, after you have this kind of power, your cultivation has been stagnant, right?" Lin Yun asked in a light tone.

Diamond Dijin's eyes widened, and he was obviously hit by Lin Yun again: "You...... How would you know? ”

Lin Yun didn't answer, but continued to ask, "Did the person who gave you the curse mark start to improve by leaps and bounds after giving you the curse seal?" ”

Diamond Dijin's eyes widened again: "How do you know everything?" ”

Lin Yun said expressionlessly, "This curse mark on your neck is called the 'Seal of Seizure'. ”

"When you are short of your own strength, as long as you activate this spell and the person who gave you this spell can temporarily lend you power through this spell seal."

"And in exchange, the fruits of your future cultivation will be transferred to the person who gave you the curse seal through this spell seal, which is called cultivation and seizure."

"This is also the reason why your cultivation has been stagnant since you possessed this spell mark, and the person who gave you the spell mark has improved by leaps and bounds."

Diamond Dijin was completely stunned, looking at Lin Yun with a shocked face, and couldn't say a word for a long time.

Lin Yun continued: "The role of the 'Seal of Retribution' is not only that, in addition to exchanging cultivation and power, it can also be used as a tool for the giver to restrain the freedom of the given. ”

"Once the giver wants to betray the giver, the giver can sacrifice the giveee through the spell seal, and directly erase the giver's life."

After listening to Lin Yun's words, Diamond Dijin sighed: "Actually, I have long understood what you said, but I have never been able to find a way to lift the curse seal." Now that you know this sigil so well, do you know what you can do to get rid of it? ”

Lin Yun didn't speak, just nodded.

"Do you really know? What exactly is the method? Tell me! Diamond Dijin's body shook, and he involuntarily took a step forward, staring at Lin Yun with excitement on his face, as if he saw the light of hope.

"The way to get rid of it is me." Lin Yun said in a light tone, as if he was talking about a trivial matter.

"You?"

Diamond Dijin first showed a look of consternation, and then looked at Lin Yun more and more hotly, as if he saw a life-saving straw: "Can you really lift this curse seal?" Please, help me remove this curse! ”

Lin Yun asked expressionlessly, "What reason do I have to help you?" ”

Diamond Dijin thought for a moment, and then said seriously: "As long as you can help me remove this curse, I am willing to do something for you, no matter what you ask me to do." ”

"How can I trust you?" Lin Yun was still expressionless.

Lin Yun will face many powerful enemies in this underground world, and it is naturally a good thing to have one more combat power now. It's just that the verbal promise is too fragile, and Lin Yun can't believe it at all.

Diamond Dijin thought for a moment, and then said with a sincere face: "I can sign a master-servant contract with you, but there must be a deadline. ”

The master-servant contract is a type of soul contract, once the master-servant contract is signed, the servant must obey the master's orders, otherwise the soul will be scattered.

As long as Diamond Dijin was willing to sign a master-servant contract, Lin Yun was not afraid that he would regret it.

"Half a month, you have no opinion." Lin Yun said directly, after half a month, he had already completed the task and got Long Yuan to leave this underground world, so half a month was enough for the contract to be signed.

"Okay, I promise you." Diamond Dijin didn't even think about it, so he directly agreed. As long as he can lift the curse mark for him, let alone only half a month, even if it is half a year, he will definitely have no opinion.

"Then let's sign the contract first." As he spoke, Lin Yun sealed his hands and summoned a scroll through the psychic. The scrolls are filled with special black runes, and there are several looming invisible runes among them.

Lin Yun handed the scroll to Diamond Dijin, and Diamond Dijin immediately took it, injected his spiritual power into the scroll, and then handed the scroll to Lin Yun.

After Lin Yun took the scroll, he also injected his own spiritual power into the scroll.

After both of them were infused with spiritual power, the scroll lit up with a brilliant light, and then turned into a white mist and disappeared into the eyes of the two.

And at this moment, the two are already in a master-servant relationship. Lin Yun is the master, and the diamond and earth gold are the servants.

"I'm already your servant, now you can remove the curse mark for me, right?" Diamond Dijin looked at Lin Yun with a pleading face.

"Come here." Lin Yun beckoned to the diamond gold, and the diamond gold ran over.

Just as Lin Yun was about to help Diamond Dijin eliminate the spell mark, a rough voice suddenly came from a distance: "Fourth, what are you doing?" Don't stop yet! ”
