Dragons are incredibly greedy creatures, possessing a strong desire for anything shiny, valuable-looking, or genuinely valuable. This applies to both good dragons and evil ones.

Muria himself noticed this trait in him due to his golden dragon bloodline. He developed a penchant for collecting various precious treasures. He had always tasked the tide giants who pledged allegiance to him to search for treasures in the ocean, never considering stopping their search.

Muria noticed the influence of his bloodline on his desires but didn't deliberately correct it. After all, there was no harm in it. Moreover, his greed for treasures was not as strong as that of true dragons.

Because of the dragons' greed, Muria came up with a very unscrupulous idea. He established specific arrays targeting the chromatic dragons and set up punitive measures. Correspondingly, he also set up a reward mechanism.

The key was that all the things Muria used to reward the evil dragons were depleted magic crystals drained of their magical energy. These crystals were byproducts of Muria's practice of arrays, and some were waste from hatchery arrays.

For Muria, these depleted crystals were basically useless except for their decorative appearance.

But when the young dragon Lena turned into a redhead loli and found him with the spellbook he gave her, Muria first fulfilled his promise, taking the young dragon Lena to visit the White Jade Shrine.

Then, under the gaze of Lena in her loli form, Muria impulsively asked her what reward she wanted. As expected, Lena asked for treasures.

In this situation, Muria threw away his integrity and directly gave her a handful of abandoned crystals that he had accumulated but hadn't thrown away yet.

Lena was delighted to see the transparent crystals piled up in her loli form. Then, happily, she took these shiny little cuties back to her room.

Lena's sudden acquisition of so many crystals from Muria naturally caught the attention of her siblings. After jointly questioning Lena about the source of the crystals, they all went to Muria.

"If we learn transmutation magic, can you give us as many crystals as you gave Lena?" one of the dragons asked.

At that time, Muria was a bit puzzled, but he quickly realized that the abandoned crystals, which he considered useless, could have a new purpose at that moment.

"Of course, not only transmutation magic, but as long as you learn any other spells, I will give you corresponding rewards as long as you are willing to learn," Muria replied to the five young dragons at that time.

So, the young dragons, eager to accumulate treasures, all became diligent learners, tirelessly memorizing spells day and night within the time limits set by Muria.

Every time they successfully learned a spell, they would eagerly find Muria. After successfully casting the spell, Muria would reward them with a corresponding amount of abandoned crystals.

Inspired by these young dragons, Muria knew how to educate the fledgling dragons. Temptation was the best method. He could use punitive arrays to restrain their behavior, forcibly suppress their bad habits, but in education, temptation would make these young dragons willingly learn, just like a donkey seeing a carrot.

Moreover, after each dragon received crystal rewards from him for learning spells, he established another system.

Muria actively assigned spell-learning tasks to all the dragons. If they completed them within the specified time, they would receive crystal rewards. But if they exceeded the time limit without completing them, well, he wouldn't scold or punish them; they just had to pay crystals as fines.

Under this system, even the dragons least interested in learning began to memorize spells desperately, striving to complete the tasks assigned by Muria within the specified time. Because every dragon was greedy for wealth.

However, just like people, dragons of the same species differed in learning abilities. Some were poor learners despite having high elemental talents, needing a long time to learn spells.

"Red dragon, Crest." After checking the spell-learning tasks of the six young dragons, Muria began to check the tasks of the fledglings. He took out a notebook containing the true names of all the dragons and their progress in spell learning.

"Here!" A red dragon with shiny red scales raised its head and walked out of the group of fledglings, coming to Muria.

Muria glanced at it and then at the notebook, nodding, "Second-tier spell, Cat's Elegance."

As Muria gave the order, a young dragon named Bertlain started chanting, cooperating with the spell model already successfully built in his spiritual sea. A faint spell light enveloped his body, making him appear much more agile in an instant.

"Go straight, rush over, then come back." Muria pointed to the opposite side of the training ground, commanding the young dragon Bertlain. He wanted to see how effective the dragon's spell casting was.

Without hesitation, the little red dragon dashed over, using the assistance spell, and indeed looked as graceful and flexible as a cat.

Encountering low obstacles, it lightly leaped over them. If the obstacles were too high, it jumped onto them like a cat, its body perpendicular to the ground, climbing over.

In just five short minutes, Muria watched the little red dragon agilely run back and forth on the training ground. When he saw Bertlain, who was back in his original position, he nodded, "You've mastered Cat's Elegance quite well."

"This is your reward." Following his own rules, Muria took out twenty neatly cut transparent crystals in the shape of diamonds and handed them to the young dragon Bertlain.

When Bertlain saw these seemingly useless crystals, his eyes lit up. He eagerly took the crystals from Muria's hand and returned to his original position with joy.

...

"Blue dragon, Adrian."

"Second-tier spell, Electric Burst."

With Muria's command, a crackling lightning ball appeared, cast by the blue dragon Adrian, and then slammed into a tiger-shaped wooden target on the training ground.

As the lightning ball hit the target, a faint "crackle" was heard, and the target now bore a scorch mark.

"Well done, twenty crystals as a reward."

...

"Blue dragon, Audric."

"Second-tier spell, Flame Burst."

After waiting for a while, Muria frowned as he watched the blue dragon chanting the spell dryly. He didn't sense any gathering of fire elements in the air.

"You haven't learned this spell on time, Audric. According to the rules, you have to pay a fine of twenty crystals."

"No, give me some more time, and I'll definitely learn this spell." The little blue dragon cried out, paying the fine was too painful for a dragon.

"Resisting to pay the fine will double it." Muria looked coldly at the blue dragon. The time he gave for each dragon to learn the spell was very reasonable. As long as they didn't slack off or sleep, they could complete it on time.

"I'll pay!" The little blue dragon reluctantly took out twenty crystals from its storage space and handed them to Muria.

"Three more days for you. If you still haven't learned the spell, you'll continue to pay fines." Muria recorded it in his notebook and marked it with a stroke. "After three days, even if you learn the spell, there will be no reward. You're already overdue."

Hearing Muria's words, the little blue dragon Audric trembled all over, dejectedly returning to its original position.

...

"Green dragon, Cecil."

"Second-tier spell, Summon Insects and Beasts."

Then, four chattering goblins holding wooden clubs appeared in front of Muria as Cecil, the green dragon, chanted the summoning spell. Cecil then looked nervously at Muria.

"The spell was successful, but the effect... Cecil, are you joking? There are only a few goblins in the group." Muria reprimanded the black dragon.

"The spell effect is poor, indicating that you've practiced too little. Reduce the reward. Based on your spell effect, you get seven crystals." Muria counted the number of goblins and determined the reward.

"Muria, this is too few. At least I successfully cast the spell, can you give me a little more?" The little green dragon tried to negotiate with Muria, wanting more crystals.

"Get lost!" Muria glared at the black dragon, coldly spitting out the word.

"Okay." Seeing Muria getting angry, the little black dragon quickly took the pitiful seven crystals and backed away.

...

"Black dragon, Lorelei."

"Second-tier spell, Flight of Insects and Beasts."

Then, a sparse group of bats appeared with Lorelei's chanting. Afterward, Lorelei, the little black dragon, looked anxiously at Muria.

"The spell was successful, but the spell effect... Lorelei, are you kidding me? There are only a few bats in the group." Muria rebuked the black dragon.

"The spell effect is poor, indicating that you've practiced too little. Reduce the reward. Based on your spell effect, you get seven crystals." Muria counted the number of bats and determined the reward.

"Muria, this is too few. At least I successfully cast the spell, can you give me a little more?" The little black dragon tried to negotiate with Muria, wanting more crystals.

"Get lost!" Muria glared at the black dragon, coldly spitting out the word.

"Okay." Seeing Muria getting angry, the little black dragon quickly took the pitiful seven crystals and backed away.
