When the time comes, I will learn some powerful things from the Thunder Magic Book and then teach them to Martina.

After all, as long as she can improve her strength, she will be happy.

After Reiner finished his breakfast, he returned to his room alone.

He sat on the bed and coughed twice, hinting at the madness of the Tong.

"Ahem! You know, the mission is complete, isn't it time to arrange the reward?"

Soon, the voice of the leader sounded in his ears.

【Here we come! 】

[Mission: Kill a Minotaur Chieftain

Current status: Completed

Mission rewards have been issued! 】

A brand new dark purple book appeared on the bedside.

Reiner picked it up and began to read it impatiently.

This book is written in the Diaster script and does not appear to be very old.

[Note: This magic book was written thousands of years ago by an elf astrologer who wielded thunder magic. The original text is in Elvish. For ease of reading, this system has specially translated it into Diastral for you.]

Reiner shrugged and continued, "Can't I translate? Elvish or not is of no importance to me."

[You can speak Elvish, but Martina doesn't.]

Reiner suddenly realized: "I see. Thank you for your thoughtful consideration. But Martina doesn't speak Diast."

The leader fell silent.

The thunder magic book in his hand disappeared instantly, and when it reappeared, the words on it changed to Demihuman language.

Reiner's lips curled up slightly, and he shook his head again: "Is it possible that although she can speak the Demihuman language, she can't read?"

The leader fell silent again.

"It's just Demi-human language, thank you."

He opened the first page and began to read the catalog. After taking a general look at the magic spells, he chose a few that sounded awesome and read them in detail.

Soon he found the thunder magic he liked.

Lightning Armor Casting Technique.

It can draw lightning to the caster, strengthening the caster's body and thus gaining superhuman strength, endurance, and speed.

This magic can not only greatly increase physical strength, but also enhance the caster's resistance to physical and magical attacks.

Moreover, this magic spell can last until the magic power is exhausted, and there is no need to cast additional spells in the middle.

For Martina, this magic was tailor-made for her.

Because when she fights, she only cares about chopping people and forgets about magic.

She learned the Wind Blade, but she'd never used it in actual combat...

Reiner continued to read carefully, and he saw some very conspicuous big words on the last line.

"Although the Lightning Armor Forging Technique can strengthen the body, excessive use will cause damage to the caster's body. The use time of this technique must be strictly controlled."

There are actually side effects.

Reiner closed the book silently.

He suddenly felt that this spell was not so suitable for Martina.

This guy gets angry easily. If he gets angry, she will definitely not control the timing of the spell.

But if you use this move as your ultimate killer move, maybe you can give it a try.

Before teaching it to Martina, he had to learn the magic himself first and then try it for her.

He would only teach it to Martina if the side effects were within his acceptable range.

Reiner opened the book again and read it carefully with wide eyes...
