Chapter 20

The Lightning Rune, as a divine power, would allow Liu Siyi to obtain the lightning elements gathered by the rune, provided he had the ability to do so. Of course, the prerequisite was that his body could withstand it. Even if it couldn't, with the Lightning Rune, any excess magical elements that might backlash would be immediately absorbed by it, preventing any harm to his body.

However, the Thunder Eagles and Thunder Birds were not capable of this. Although they were powerful fifth-tier units, their ability to absorb power had its limits; otherwise, they would burst and die.

However, Liu Siyi and the others were unaware of this. The Thunder Eagles and Thunder Birds had never practiced before. Suddenly, they noticed a large amount of lightning elements around them and realized they could become stronger by absorbing these elements, so they naturally wanted to absorb as much as possible. Although Liu Siyi had inherited the legacy of a Legendary Mage, he had never practiced in a different world or guided others in practice. Even the meditation of a Legendary Mage was typically done alone in an undisturbed environment.

Without the interference of the Thunder Eagles and Thunder Birds, there would have been no problem with the practice. However, with such significant interference, issues arose.

Fortunately, tragedy did not occur. Since it was just the beginning of the meditation, the speed at which lightning elements were gathered was not very fast, and the amount was not large. The speed at which the Thunder Eagles and Thunder Birds absorbed the lightning elements far exceeded the speed at which the elements were gathered. This immediately created a gap, interrupting Liu Siyi's continued meditation.

It was fortunate that the meditation was interrupted; otherwise, absorbing too many lightning elements would have caused the Thunder Eagles and Thunder Birds to burst and die.

"Screech!" A series of high-pitched eagle cries echoed as the Thunder Eagles and Thunder Birds emitted dazzling lightning. The Thunder Eagle's purple glow was particularly intense, so much so that Liu Siyi dared not turn to look, to avoid injuring his eyes.

The light persisted for a long time, and this glow would certainly be visible from dozens of miles away. However, there was no threat around them.

After a while, the blinding light gradually dimmed, and Liu Siyi could finally squint to see the four large figures in the light. Finally, the light completely disappeared, and he could clearly see the Thunder Eagle and Thunder Birds in front of him.

At this moment, the Thunder Eagle's body was flowing with a mixture of purple and faint golden lightning plasma, and the faint crackling of electricity could be heard continuously. The purple-golden plasma clearly indicated that its lightning power had become even stronger.

The Thunder Birds were similar, but the change was not as significant as the Thunder Eagle's. They remained blue, much like the Thunder Eagle's previous state.

Not only that, but their bodies had also undergone significant changes. Originally, the nest was divided into five parts, with each one sleeping in one section. Now, it was clear that the space in Liu Siyi's section had become much smaller.

"Master, I feel my power has become much stronger," the Thunder Eagle said, spreading its broad wings, with the purple-golden current shining brilliantly.

Indeed, the Thunder Eagles and Thunder Birds could absorb lightning to grow stronger. Liu Siyi thought this was similar to practice, just in a different way.

"However, the power is strong enough, but it's so strong that I can't control it freely," the Thunder Eagle said. As soon as it finished speaking, a purple-golden current from its body instantly shot towards the wall nest below and exploded with a "bang!" like a bomb.

Fortunately, the wall nest was protected by the laws of nature and suffered no damage.

"Is it the same for you?" Liu Siyi frowned and asked the three Thunder Birds.

"Screech!" The three Thunder Birds shook their heads and spread their wings, indicating that they could control their newly acquired power freely.

Why, despite absorbing the same lightning elements, could the Thunder Eagle not control its power, while the Thunder Birds could?

Liu Siyi didn't know the reason, but this didn't stop him from carefully recalling and thinking about the meditation process.

"I think I know the reason," Liu Siyi said. "When I meditated, a lot of lightning elements gathered around my body, and you absorbed these elements. The Thunder Eagle, being closest to me, absorbed the most. Although it gained the most power, it exceeded its control. As for you, the amount of lightning elements you absorbed did not exceed your control, so there was no problem."

He wouldn't reveal the powerful secret of the Lightning Rune, just mentioning the meditation practice was enough. Thinking about it, Liu Siyi had already figured out why the Thunder Eagle had evolved and why the original eight Thunder Birds had intelligence exceeding that of ordinary units.

The "refresh" of wild monsters had many possibilities, but 99.9% of the time, they were ordinary units, with a very small chance of elite units. Of course, as a natural hero, wild monsters could also be "refreshed." However, these heroes would usually start wandering around shortly after appearing, so it was almost impossible to see a natural hero among wild monsters.

Clearly, the Thunder Eagle had a high chance of being an elite unit from the start, but it was also possible that it absorbed lightning from natural occurrences. Once lightning appeared, the Thunder Birds could absorb its power, similar to practice. The more lightning absorbed, the stronger they became, and evolution was normal. Otherwise, how could the Thunder Birds use intelligence in the battle against the dwarves?

Of course, perhaps the Thunder Birds initially didn't realize that being struck by lightning could enhance their power, but who knew about the past? What Liu Siyi was more concerned about now was: had the Thunder Eagle advanced to the sixth tier?

Thunder Eagle, a high-level elite variant of a fifth-tier unit.

This was the information obtained from the Scouting Skill.

Variant! Another variant!

Indeed, the lightning produced by a fifth-tier Thunder Bird was light blue, while the Thunder Eagle's was deep blue. Only at the sixth tier would the Thunder Eagle's lightning add a hint of purple, and only at the seventh tier would it produce purple-golden lightning.

However, now, a high-level fifth-tier Thunder Eagle could produce the purple-golden lightning that only a seventh-tier Thunder Eagle could possess, which was undoubtedly a variant.

As for why this variant occurred, Liu Siyi wouldn't reveal his speculation, but he was very puzzled. Could it be that the Thunder Eagle absorbed the lightning laws from the Lightning Rune while absorbing the lightning elements?

This idea was not far off.

It is well known that fire comes in many forms, as do water, earth, and wind. Lightning is the same, possessing far more power than ordinary lightning.

As a divine Lightning Rune that could only be condensed at the high ninth tier, the lightning elements it gathered were not just ordinary lightning elements but also some special lightning from this world. Although the amount was minimal, it was precisely this that the Thunder Eagle absorbed, causing it to possess far more power than it could control.

This also led to the fact that when Liu Siyi later used the same method to enhance the Thunder Birds' strength, such variants rarely occurred.

As for why this Thunder Eagle could use purple lightning from the beginning, it could only be said that when it was struck by lightning, it perhaps luckily absorbed higher-tier lightning.
