"Purity?" After hearing this word, Mei Lin couldn't help but be stunned, "What do you mean······"

"Yes," Al nodded a little excitedly, holding up a piece of Fire Stone and handing it to Merlin, "Teacher, you see, due to the problem of craftsmanship, the Fire Stone that we can mine now is mixed with many impurities, and I suspect that these impurities prevent Eevee's contact with the Fire Stone from evolving, and after Eevee swallows the Fire Stone, these impurities will be digested, and Eevee has contact with the Fire Stone and has evolved." So will it be possible that after the impurities are removed, the Fire Stone can cause Eevee to evolve?"

"You have a point," Merlin put her chin on her hand and looked at Al with a smile, "I didn't expect you to have such an amazing idea, maybe we all went into a misunderstanding before, it's good to be young." ”

"Hey, hey. Al scratched the back of his head and smiled sheepishly.

"In that case, let's start experimenting. ”

In the lab, Merlin and Al were nervously experimenting, and the fire stone in the crucible on the table was gradually turning into a liquid state, bubbling with bubbles.

Mei Lin frowned slightly, "No, the firepower is still not big enough." ”

"That's easy, leave it to me," Al touched the fire spirit beside him, "Fire spirit, use a jet flame on the alcohol lamp." ”

"Bouie~"

"Whew-"

A large flame erupted, and the flames on the alcohol lamp immediately soared a lot higher, and the high temperature directly melted the fire stone into liquid.

"You're yours, Al," Merlin complimented, "it's time to filter, in that case, come on, Sun Elf." ”

"Yi~"

The sun elf answered, a flash of blue light flashed under his eyes, and an invisible telekinesis wrapped in the reddened crucible of fire, gently lifted it, and poured it onto the filter that Al had already prepared.

"Tick, tick"

"Whew-"

The liquid Fire Stone slowly dripped down, and the impurities were filtered out and left on the filter screen, and the dripping Fire Stone condensed on the table, forming a crystal round orange-red stone.

"Oh!

"This," Merlin reached out and picked up the orange-red stone, "it's the real Fire Stone!"

"Alright, Teacher," Al excitedly pulled Merlin's arm, "let's go experiment." ”

"Okay, let's go. Mei Lin looked at her usually very steady disciple with some amusement and pulled her like a child at this time, and couldn't help but sigh in her heart: 'He is indeed still a child, but his identity determines that he cannot have a happy childhood like an ordinary child. ’

However, at this time, Mei Lin's heart was also a little excited, because once this experiment was successful, it would not only mean a great glory, but more importantly, it would be a promotion of Camelot's local military strength, after all, the super iron tyrannosaurus, duck-billed flame dragon and electric shock monsters discovered before, although powerful, but the cost was very high, and the number of elves such as ironclad tyrannosaurus was not much, and it could only be assembled for those elite troops, and the intimacy evolution method of the sun elves and moon elves was a little too cumbersome, and the improvement of military strength was very limited. However, this experiment is completely different, the Evolution Stone and Ievee are very common in the Camelot place, as long as they are combined, they can become a powerful combat force, and the military strength of the Camelot place will be greatly improved, enough to compete with or even suppress the old enemy Rome.

"Alright, now is the most exciting time," Al looked at Merlin with an excited face, "Alright teacher, let's get started." ”

"Well," Merlin nodded, her face calm, but her slightly trembling hand betrayed the excitement in her heart, "Go ahead, Fire Stone." ”

Merlin threw out the purified Fire Stone in her hand, and the crystal gem landed on the head of an Eevee.

At this moment, their breathing seemed to be still, staring at the Eevee.

One second······

Two seconds······

Three-second ······

"Boom!"

White light!

"It worked!"

———————————— Divider (Elementary) ————————————

"Yes, very well done, Arthur boy," King Uther smiled as he looked at the report that Merlin had sent him, "and that would increase the country's military strength dramatically, and Arthur had given me a great gift." ”

"Hmph, Rome, wait. ”

"Daddy, Daddy!" Kay cheered in with the letter Merlin's letter, "Look, Al is famous!"

"Look at your appearance, what are you panicking!" Archduke Andre glared at Kai dissatisfiedly, "When will you get rid of this frizzy problem?"

Kai was reprimanded by his father, but he was not annoyed, he stuck out his tongue with a hippie smile, and when he heard his father ask about Al, he hurriedly handed over the letter in his hand, "Dad, you see, Al has discovered the other three evolutionary forms of Eevee. ”

"What?" When Grand Duke Andrei heard this, he hurriedly snatched the letter, but there was not much joy on his face after reading it.

"What's the matter, Dad, aren't you upset?"

"Happy?" said Grand Duke Andrew, glaring at Kai again, his beard blowing high, "What's there to be happy about? I was going to teach him to be a good elf knight (trainer), but you were good enough to push him to Merlin at once." ”

"What's the matter, isn't it good to be an elf scholar?" asked Kay, puzzled.

"It's good for other kids, but it's not enough for him······ Alas," Grand Duke Andrei sighed, "forget it, don't ask, you're too young to understand this." ”

"What. Kai muttered unhappily.

———————————— Divider (Advanced) ————————————

"Mei Lin, that girl, you have a very good low-level," in the laboratory, Dr. Ohki, whose hair was a little gray, looked at the "Scholar Times" in his hand, which prominently published that Al Chenggong had learned about the three evolutions, "It actually solved the problem that we had not been able to figure out." ”

Just then, the doctor suddenly smelled a burnt smell.

"What does this taste like?

—————————— congratulations on the achievement: Master of the Dividing Line—————————

In a dimly lit room, a middle-aged man with blond hair sits upright on the throne, holding a copy of The Scholar's Times.

"Senior Sister Mei Lin's disciples, forget it, leave them alone, my experiment is about to succeed, as long as there is 'it', this world-hahahahahahaha······hahahahahahaha

The man stared at his outstretched palms and laughed maniacally.
