To be honest, Lin Yu already wanted to agree when he heard these reasons, because being able to drive such an undead army could really do a lot of things.

And Gu Aotian said the sentence that made Lin Yu's heart move the most: "It can make you die a lot less!"

Lin Yu almost didn't hesitate to agree, "I'll learn necromancy from you!"

"That's right!" Gu Aotian looked like he had succeeded in his treacherous plan, and said with a wicked smile, "Come, let's take the first lesson first!"

"First lesson?" Although Gu Aotian's voice seemed to be a little treacherous, Lin Yu didn't think much about it, "What do you want to learn?"

Gu Aotian smiled, "Learn how to make a lich first!"

"Oh!" Lin Yu suddenly realized that Draenor, the culprit who built the slave prison, was still being held. At that time, Gu Aotian proposed to make him a lich, so Lin Yu spared his life, and then handed it over to Hei Tielie to dispose of, according to Gu Aotian, as long as he didn't let him die.

Thinking of this, Lin Yu's interest increased greatly, and he said, "Teach me quickly!"

"Don't worry...... Gu Aotian didn't expect Lin Yu's enthusiasm to be so high, "We first have to go and see if that person is dead! If he doesn't die, we have to make him die happier......

Draenor was locked in a cage by Black Iron Lie, according to the old dwarf, he called him to treat his body in the way of others, and if anyone is angry in his heart, he should go to Draenor to vent, because the way of heaven is good reincarnation.

So when Lin Yu saw Draenor, he had already been tortured to the point that he was not human, not only his clothes were tattered, his whole body was scarred, but the whole dark circles were very serious, because Hei Tielie asked a team of dwarves to greet him specifically and not let him sleep, lest he recover his mental strength as soon as he slept.

"Please!" Draenor saw Lin Yu coming, he frantically grabbed the edge of the cage, and then yelled at Lin Yu, "Kill me, stop torturing me, let me die!"

"Why did you want to kill you?" Lin Yu pretended to be very innocent and said, "I came to let you go!"

As he spoke, in the midst of everyone's puzzled gaze, Lin Yu opened the cell door.

"Really?" Draenor asked, confused, "why did you let me go!"

"Of course, it's because a fourth-order necromancer is very rare!" Lin Yu said innocently, "With a mage like you, it's a tiger with wings for our forces!"

With that, Lin Yu walked to the cage, reached out to hold Draenor, and took him out.

The dwarves guarding the prisoners around were stunned, this was a heinous villain, he had slaughtered many of his fellow dwarves, how could he let him go so easily?

One of the dwarf guards couldn't help but say to Lin Yu: "Lord Lin Yu, you can't let him go, he ......"

Lin Yu waved his hand, not letting the dwarf continue, but personally leading the way for Draenor.

"Hahaha!" Draenor walked out of the cage and breathed a sigh of relief, although he was now physically and mentally tired to the extreme, but now it seemed that there was a way to live, and he seemed to be alive again, he held back his excitement and swore solemnly, "Lord Lin Yu, in the future, I, Draenor, will definitely serve you!"

"It's easy to say, it's easy to say!" Lin Yu smiled slightly, and then seemed to remember something again, so he continued to say to Draenor, "By the way, don't you really want my Scourge Ring?"

Lin Yu took off the Cataclysmic Ring from his hand again, handed it to Draenor, and said, "In order to welcome you to join our forces, this ring should be regarded as a welcome gift for you!"

"This ...... How embarrassing. Draenor was about to shirk it, but Lin Yu had already taken off the ring, grabbed Draenor's right hand at the same time, and put the ring on his right index finger.

"Sure enough, this Immortal Bone King's Cataclysmic Ring must have a great necromancer like you to be worthy of it!" Lin Yu said complimentally.

But Draenor's attention was already completely on the Scourge Ring, and he could clearly feel that this ring contained a lot of dark power and soul power, which was the treasure he had always dreamed of, and when the dream was illuminated by reality, he suddenly felt a cry of joy.

"How's it going, are you happy?" Lin Yu asked with a smile as he stood behind Draenor.

"Open...... Happy," Draenor said with a palpable affection, he raised his right hand and raised the Scourge Ring high, then looked up in fascination and said, "I'm so happy!"

"That's good!" Lin Yu nodded, and then a red light suddenly flashed in his right hand, first a regular hexagonal shape appeared, and then the hexagonal shape turned into a military thorn, and the fighting spirit in his hand surged, stabbing directly towards the back of Draenor's heart!

Draenor, who was completely immersed in joy, didn't have time to react, only felt that his heart suddenly hurt, and then he looked down at his chest, just in time to see the spur that had penetrated his heart, and he only then realized that he seemed to be dying.

"No, I'm not reconciled!" Draenor roared, how could he die so easily when he had just rediscovered the light of day and had obtained the treasure he had always dreamed of.

At this time, Draenor's body was dead, but he still had a grudge, and he seemed to be unwilling to close his eyes.

And Lin Yu clearly felt that at this time, a soul power was condensing in Draenor's body, which was full of dark resentment and unwillingness, condensed a new soul, floating in the air.

The surrounding dwarf guards were already stupid at this time, at first they thought that Lin Yu was really crazy, or was controlled by that necromancer, otherwise Lord Lin Yu would not have released this evil man with a heinous crime, and gave him the treasure on his body.

But after seeing Lin Yu kill this person neatly, what happened later surprised the dwarf even more!

"Okay, it didn't take much effort," in the Cataclysmic Ring, the soul skeleton of Gu Aotian appeared at this time, and instructed Lin Yu, "Quick, while he is still a little brainless, give him a soul attack!"

Lin Yu quickly mobilized his soul power, and then aimed at the newborn soul in Draenor's body, and quickly attacked the soul, directly knocking this soul out of the body, and at the same time, this soul seemed to have weakened a lot and became more and more transparent.

"Alright, finally hit his body with your soul mark and you're done!" The Bone Proud Soul Skeleton waved his hand and summoned the Scourge Ring to him.

Lin Yu slapped the soul mark on Draenor's soul as he spoke, and then asked, "This is the lich?"
