"Ah!!!!!h

After a full five minutes of upheaval, the female demon hunter finally couldn't hold back the pain anymore and let out an extremely piercing scream.

She felt that every muscle and cell in her body was being torn apart and reorganized by the powerful energy, and the feeling was almost equivalent to the continuous erosion of her body by evil energy after eating a demon's heart.

And that's not all!

She couldn't help but recall the most painful memories of her life, including the fall of the undead army led by Arthas in Silvermoon, the tragic deaths of her parents and siblings, the death of her friends at the hands of demons during the Outland Wars, and the transformation of her former boss from the Frozen Throne into a senseless ghoul......

The memories that tortured and tormented her were like magic replays, repeating them all the time.

The poor elf didn't even know if it was the memories that made it more painful, or the intense stimulation transmitted by the nerves to the brain that was more painful.

The only thing she knows is that she has to live!

At least not die until you have your revenge!

Backed by a strong desire to survive!

Although the scales on the surface of the female demon hunter's skin began to crumble, and the green blood containing evil energy splattered everywhere, it continued to heal very quickly.

Under the double torture of destruction and regeneration, the essence of her life has finally been transformed.

In less than a minute, the conspicuous horns on the head, the scales, wings, and claws on the surface of the skin were all gone, and the near-flawless body curves of the blood elves were replaced by them.

"How does it feel, Sheena?" Zhang Cheng asked with interest, touching his chin.

"I ...... I don't know......" The female elf slowly got up from the ground and gently stroked her almost naked body.

She could feel that although she had lost the tattoo that Illidan had personally carved on the surface of her body to suppress demonic spirits, as well as the original powerful power of evil energy, her body had become completely different from before.

To be precise, it is as if it has been strengthened and sublimated from the body to the soul.

In order to confirm this, Sylna stretched out her right arm and grabbed the imp servant who was cleaning the dust in the room, and violently activated her ability to seize the blood energy in the opponent's body.

It's less than a second!

The poor creature that didn't react was washed alive into a dry and cold corpse that seemed to have been dead for decades.

At the same time, the vanished tattoos on her upper body were lit up again, and green evil energy poured into every corner of her body along the veins, and the smoothness was simply different from before.

"What have you done to me?" the elf looked up, a look of disbelief on her face.

You must know that since becoming a demon hunter apprentice, she has been tormented by evil energy and demon souls almost all the time, and even has nightmares when she sleeps.

Zhang Cheng smiled and shrugged his shoulders in response, "It's very simple! I have maximized your potential. Knowing why Illidan is so powerful, no matter how many demons he kills and devours, there will not be even the slightest danger of exploding his body? Many people believe that this has something to do with his deal with the Origin Dark Titan Sargeras. Of course, I don't deny it, but what really allowed Illidan to withstand such a powerful evil power was that he had changed his constitution with the water of the Well of Eternity. ”

"Forever...... The Well of Eternity?!" Sylna's mouth grew in surprise.

"That's right, the Well of Eternity, the point where all of Azeroth's magical energy used to converge. You can imagine that the magical energy that pervades the entire world is now gathered in a well, how powerful and pure its water must be, even a little bit is enough to change the life form of mortals and make them evolve to a higher level. The potion I just gave you contains a drop of water from the Well of Eternity......" Zhang Cheng explained with a smile on his face.

However, he didn't say that the Well of Eternity was somehow part of the Star Soul that Azeroth had conceived.

At that time, Akmund the Polluter tried every possible way to ascend to the World Tree, not only to seize the entrance hidden under the tree to the inner core of the star, and to continuously extract the star soul to evolve himself into a member of the Titans.

In fact, in the eyes of the true higher-ups of Azeroth, these are no secrets at all.

Undoubtedly, like all those who yearn for power, Zhang Cheng also longs for the day to seize the powerful power that this planet has bred.

But the problem is that he is far from strong enough to contain the huge magical energy of a planet, plus there are countless guardians, including Titans, it is better to keep a low profile for the time being.

Once he had found a way to do it, he didn't mind destroying Azeroth to put an end to the endless battle.

"I see!" Sylna nodded in realization. "But I don't understand, why do you use such precious materials on me? Am I more than just a test subject to you?"

"Yes, you're a test subject, but not a test subject in the ordinary sense of the word. Specifically, the experiments I have conducted on you are very important, especially to help me gain insight into the evolution of life forms in Azeroth over tens of thousands of years. In addition, our dear Lord Illidan of the Outlands has made a clear request that I find a potion that will increase the conversion rate of Demon Hunters. ”

After that, Zhang Cheng added Gruul's blood drop by drop to dozens of bottles of green evil energy solvent, and handed it to the other party without looking back: "Give it to Illidan for me, he will be satisfied with this thing." ”

"As you wish, master. ”

Sylna didn't try to ask any more questions, and after simply covering the key parts of her body with her tattered clothes, she took the potion and turned around and walked towards the deepest part of the Dark Temple.

Seeing the female elf disappear at the end of the dim corridor, Zhang Cheng immediately turned his gaze to the empty corner, and joked with a smile: "Your Royal Highness Princess, how long are you going to stand there?"

"Damn, when did you find out?"

With a familiar voice, Onexia lifted the invisibility spell and walked out with a frown.

"Don't use this little trick next time, I'm sure Varna will be aware of your presence. Zhang Cheng poured nearly half of the remaining Gruul's blood into another violet solution and handed it directly to the Black Dragon Princess.

The latter sniffed lightly with his nose, and a strange expression immediately appeared on his face: "I smell the breath of the power of the earth!

"Goron, a special species created by the Titans and endowed with the power of the earth, like the black dragon, has the terrifying power to change the landscape. Drink it, and if nothing else, this bottle should be able to wake up the sleeping part of your body. Zhang Cheng urged with some impatience.

As the Dark Door was about to open, he realized that his trip was coming to an end.

When the Alliance and the Horde poured into the Outlands, it was the deadline for him to leave......
