The lower level of the Blackstone Tower is home to a large number of evil creatures that have surrendered to the power of the Black Dragon Prince, including the trolls of the Burning Thorn Tribe, the ogres of the Spike Tribe, and the orcs of the Blood Axe and Fire Mark Clans.

Even the orcs of the Blood Axe Clan used two huge wolves, Kizruel and Harleken, to create a steady stream of wolf cubs, and then used the dark magic of the warlocks to ripen in an attempt to build an army of wolves.

As a close confidant of Nefarian, the elite Dragonman General Dakisas is the commander of this mixed army, and is also tasked with testing the combat power of the Colorful Dragonmen and the Colorful Broodlings.

But today, instead of inspecting his men who often make trouble, or observing the colorful dragons with lilac scales, he stared at the huge egg not far away.

To be exact, that thing can no longer be called an egg, but rather a sarcoma.

In particular, the cuticle that covers the uneven and wrinkled surface not only does not have a single scale, but also keeps squirming, as if something is about to break out of the shell.

Although he had seen many of his master's horrific experiments, none of them had ever given him such a strong feeling of suffocation, as if once the monster inside hatched, it would kill him immediately.

Dakisas couldn't understand why the Black Dragon Prince would indulge a human in such a dangerous experiment on his own turf.

Just last week, six precious spellcasters of the Fire Seal Clan were killed due to a demon-summoning ritual, and at least four spiked ogres were nearly burned alive by the eruption of demonic flames.

And the culprit of all this is the young human standing in front of the huge sarcoma at this moment, with a crazy light in his eyes.

If it weren't for Nefarian's order, no one would be allowed to interfere with what the other party was doing, and he would have wanted to directly tear the other party's throat and feed the wolf with the corpse.

But unfortunately, in the Black Stone Tower, no one can disobey the orders of the Black Dragon Prince, even if they disobey the Yang and Yin, they may be punished worse than death.

So although his heart was full of all kinds of dissatisfaction, he could do nothing but watch.

......

At the same time, Zhang Cheng, who was standing in front of the huge flesh egg, muttered to himself in a voice that only he could hear: "Protect the body of the dragon, the blood of the demon, and the energy from the crater crystal. Now even I wonder what it's like when you hatch. ”

As soon as the words fell, the Doomsday Guard next to him, who was wearing magical armor and holding a double-edged giant sword, suddenly reminded: "Master, I suggest that you better retreat a little, at the current speed, it won't be long before the energy conceived in it will produce an eruption." ”

"Oh, tell me, what do you feel,?" asked Zhang Cheng without looking back.

This powerful demon, which is more than five meters tall, was summoned by a ritual last week.

Unlike the previous small characters who belonged to the cannon fodder of the Burning Legion, it is a mid-level commander, not only mastering excellent melee combat skills, but also proficient in strategy and tactics, and also including several types of spell abilities such as shadow arrows, evil energy fire rain, and soul devouring.

The Doomsday Guard named Pollack hesitated slightly, and quickly replied, "It's Chaos, my master. I see a soul full of anger and tyranny, and I really suggest we get out of here or wait for it to ......."

Before the Doomsday Guard could finish speaking, Zhang Cheng suddenly put his index finger on his lips and made a silent motion.

When the former saw it, he immediately closed his mouth and put on a taciturn appearance

Next Second......

There was a violent vibration of energy in the air, followed by Nefarian, the black dragon prince, who appeared out of thin air in the center of the hall.

I saw that he didn't pay attention to anyone, first carefully observed the changes in the flesh egg, listened to the more and more powerful heartbeat inside, and a satisfied expression appeared on his face.

"Wonderful! This little creature is getting stronger and stronger, and when it is born, it will surpass Cromagus and become the most perfect creation. My dear friend, you have been a great surprise. ”

"Hehe, you've really won the prize. Here's a note from all the experiments I had with a recent incident, and a potion recipe that has been optimized many times, so you can just follow the steps above and you'll be able to create enough dragons to sweep across Azeroth. I sincerely wish you the best of luck in defeating your enemies and ascending to the supreme throne. With that, Zhang Cheng handed over a secretly altered note.

If the Black Dragon Prince really follows the above steps to create colorful dragon beasts, then the result will not be an invincible army, but a group of crazy monsters full of hunger and thirst in their hearts, eager to kill everything and destroy everything.

Perhaps it doesn't take the adventurers to end his life, and the unsatisfied drake beast will take the first step to turn the Blackstone Tower upside down.

"You actually took the initiative to hand over the experiment notes?" Nefarian was visibly taken aback, quickly opened and flipped through them, and after confirming the contents, he couldn't help frowning.

The reason is very simple, as an expert who likes to engage in biological research, he can clearly see that this notebook is real, but he doesn't understand why the other party is doing it?

According to his thoughts, this somewhat crazy young man in front of him should keep this notebook to hang his appetite, and then find an appropriate time to exchange it for benefits.

Zhang Cheng undoubtedly sensed the Black Dragon Prince's doubts, and explained expressionlessly: "Your Highness, I have completed the experiment and obtained the knowledge I want, so there is no point in continuing to stay. ”

"I see, you want to leave. Nefarian looked abruptly realized.

"That's right! I'm going to take a trip to the Hammer of Doom in Firas to visit the high-level elven mages who lived in the ancient city of Eresaras more than 12,000 years ago and discuss the mysteries of magic with them. Zhang Cheng half-truthfully said the destination of his next stop.

When Nefarian heard this, his eyes flashed with a strange light, as if he was thinking about something.

After about a minute or two, he smiled and nodded, "Okay, I accept your goodbye, and I look forward to your next visit." Yes, this is the reward I promised you. Also, if you're back in Stormwind, why not pay a visit to my sister, whose human name is Katrana Presto. ”

"Thank you for your generosity and kindness, and if I don't mind, I'm going to leave now. After all, I still need to absorb more knowledge to improve myself and evolve to a higher level of life. Zhang Cheng deliberately pretended to be crazy and bowed, turned around and disappeared with the Doomsday Guard into the intricate passages on the lower level of the Black Stone Tower.

As soon as he left on his front foot, Dakisas leaned in and probed in a polar voice, "Master, why did you let him go?"

He is not a mortal in the ordinary sense of the word, let alone the kind of dead brain who regards good and evil as the only criterion for living in the world. Don't worry, he won't be our enemy, but a potential ally of the Black Dragon Legion, at least the human kingdom will never accept his crazy biological research......"
