Crossing the border between the Silver Pine Forest and the Hillsbride Hills, Zhang Cheng soon chose an inconspicuous valley as his temporary base of residence.

As soon as Kulo Kirba's huge reminder landed, the frightened horse immediately fled into the woods as if it were crazy, and disappeared without a trace in the blink of an eye.

However, Zhang Cheng couldn't care about chasing the mount at the moment, so he quickly jumped off the dragon's back, and with the help of the small number of tools carried in his waist bag, he began to check the various indicators of the dragon's body, especially the changes in blood.

You must know that for magical creatures, blood is not only a normal function of transportation, metabolism, immune system and other normal functions, but also the center of energy operation, if you want to find out their strength, you only need to take a little blood and analyze the amount of energy contained in each milligram of blood.

Of course, this calculation method, which is obviously tinged by modern science, was original to him, and most mages simply take the amount of blood from a standard flask and judge the strength according to their own estimates.

"Father, are you worried about my changes?" Kulo Kerba seemed to be accustomed to being drawn blood, and instead of resisting, he opened his mouth very cooperatively, allowing the sharp needle to pierce the soft lining of his mouth.

"Shouldn't I be worried? You must understand that all forms of power and evolution cannot happen for nothing, much less without paying a price. Zhang Cheng explained as he squeezed the blood in the syringe into several test tubes, and then injected a small amount of energy with different properties for observation.

In just a few seconds, the test tube infused with arcane energy burst out with brilliant light, as if even the sun in the sky had lost its color.

There is no doubt that the arcane energy contained in Kulo Kirba's blood is the highest, and even far exceeds the limit of most senior mages and even ** masters in unit volume.

If it could learn magic, it would be easier to surpass most casters than it would be to eat or drink.

But alas, despite the dragon's ability to think clearly and speak, its intelligence level is the same as that of a child of seven or eight years old, full of curiosity about everything around it, and it always asks this and that, as if it has kicked a hundred thousand whys.

This level of intelligence, not to mention learning jerky and difficult knowledge of magic theory, is quite difficult for slightly difficult math problems.

But if this amazing magical talent was allowed to be wasted, Zhang Cheng felt that it was too wasteful, at least in his concept of quick success, he would never allow this to happen.

Just when he felt a little tangled and had a headache, several other test tubes, which were originally calm, suddenly erupted into violent reactions.

I saw that the red blood that flashed violet luster from time to time suddenly began to glow, some showed a warm golden light, some began to burn, some condensed into biting ice, some continued to release white electric light, and the last bottle emitted an ominous black mist.

What's even more shocking is that after a brief resonance of energy, all the test tubes revert back to the violet brilliance that arcane energy can only have at the same time.

With such a drastic and rapid energy transformation, not to mention Zhang Cheng, who had no clue at all, even if Dalaran's ** master came, he would be dumbfounded.

"Incredible! Incredible! Light, Shadow, Elemental, Life...... All forms of energy are eventually transformed into arcane and integrated into the bloodstream, with little or no loss, which is simply not in line with the theories recorded in the books. Is it a problem with the dragon breed of A Song of Ice and Fire, or is there some kind of mutation during hatching?energy...... Arcane ...... Engulf...... Conversion ......"

He was like a madman who had discovered a "new world", with a feverish sparkle in his eyes and a mouth that kept talking to himself.

In contrast, Kulo Kerba was much calmer, slowly lying down and yawning with his fangy mouth open.

As a test subject who has been regularly drawn from birth and subjected to various tests, it has seen too many "fathers" of unreasonable madness, and it has not felt that there is anything to make a fuss about, and it has fallen into a semi-comatose state.

In short, one man and one dragon settled in the valley like this, and at least Kulo Kerba knew that they would not easily move until the "father" got the answer he wanted.

Time flies, and ten days have passed.

With the powerful power of the mage, Zhang Cheng built a makeshift laboratory out of clay, wood and stone, and spent the rest of his time in a simple room while hiding in it to explore the mysteries of dragon blood.

As for Kulo Kirba, he occasionally hunts some animals around to fill his stomach, and the rest of the time he spends his time absorbing the rich magical energy in the air and then falling asleep.

It had only been in Azeroth for a few days, and its body had grown to an astonishing forty meters, almost no different from those guardian dragons that had lived for hundreds or thousands of years.

I'm afraid no one will believe that this little guy is only about a year old since it hatched, and it is still growing at an incredible rate, and it will not take a few years to become a "desolate beast" in the true sense of the word, a terrifying monster that can destroy a city or even a country by itself.

Of course, if the change in size alone was not enough to arouse Zhang Cheng's research interest, what really interested him was the extremely malleable magical talent of Kulo Kirba.

Most of the formed spells and different kinds of energy will be absorbed and stored in front of the dragon, as if something is being conceived inside the huge body.

This means that all spellcasters can only use summoning or transformation spells in front of Kulo Kirba and defeat them by colliding head-on, otherwise they will be replaced with spells such as fireballs, ice arrows, and arcane missiles, which will be absorbed as energy before they can fly closer.

Although there is a ceiling on this absorption, it is not available to most mages at all. In addition, if you fight a dragon hand-to-hand, as long as your brain doesn't go crazy, no mage will try it easily.

"To put it simply, it's magic absorption and immunity, it's really an incredible ability......" Zhang Cheng concluded with a wry smile as he stared at his bloodshot eyes.

As a mage, he knew all too well how amazing Kulo Kirba's abilities were right now, and coupled with the deadly spitting mixed with arcane energy, he was simply a natural nemesis for spellcasters.

On top of that, the magical contract he used to hatch the dragon eggs did not fade as the dragon grew stronger, but became more and more intimate, sometimes even telepathically aware of each other's feelings......
