After finding what he was looking for, Rod didn't forget to perform a quick sacrifice, effectively erasing all traces.
As he felt the slight increase in strength within his body, Rod looked disappointed.
This guy really was useless.
Holding the two items in his hands, Rod first opened the mysterious book.
Since it was something kept so carefully, it probably wasn't just an ordinary book.
After flipping through a few pages, Rod was surprised to discover that it was a spellbook containing various types of magic.
If he wasn't mistaken, this was likely left behind by the murdered witch.
Judging by the thickness of the book, it contained at least a hundred different spells.
However, after skimming through it, Rod felt somewhat disappointed.
Most of the spells recorded in the book were nothing more than simple tricks.
For instance, the Mage Hand spell, which allows a mage to create an invisible hand to fetch distant objects—though it could only move light items.
Light, which creates a glowing orb to dispel darkness, but has no offensive power.
Knock, a spell that can unlock any type of door or lock.
Most of the spells were rather useless.
Of course, there were some practical ones, like the Revealing Spell, which could make spirits or hidden traces appear, or the Holy Light Spell, which was specifically effective against evil spirits.
After understanding the content of the book, Rod decided to sacrifice it immediately.
In an instant, all the magical knowledge from the book was engraved into his mind.
Casting magic requires mana, which exists in every corner of the world.
To become a sorcerer, the most important requirement is having a sufficiently strong mental strength.
Only with strong enough mental power can one properly control the wild magic present in the world.
This was no issue for Rod.
After sacrificing so many werewolves, along with a witch and evil spirits, the sacrifices had already given him a frightening level of mental strength.
Most ordinary sorcerers couldn't compare to him in terms of mental power.
The only thing holding him back was his lack of knowledge about how to use that power.
Now that he had absorbed the knowledge from the spellbook, he would gradually learn how to harness his mental strength.
Mastering magic was only a matter of time.
"These spells should be enough to deal with cursed spirits."
However, killing the source of evil beneath the villa would likely be more troublesome.
But there was no rush.
Rod shook his head and took out the flint.
He gently struck it, and a large white dog appeared out of thin air. Its eyes were as big as teacups, and it was roughly the size of a large dog.
Looking into its sharp, intelligent black eyes, Rod could tell this dog was no ordinary animal.
According to the fairy tale, this flint could summon three dogs in total, each corresponding to the guardians of the copper, silver, and gold treasure chests.
This dog was the weakest, tasked with guarding the copper chest.
The guardian of the gold chest, however, was a dog with eyes as large as a lighthouse.
When summoned, these dogs would obey the commands of whoever held the flint.
Now, this was interesting.
Rod rubbed his chin in thought.
Three treasure chests, three powerful guardians, existing for who knows how many years.
If they were only protecting treasure chests, was such an elaborate setup necessary?
Not to mention, the flint that could summon these guardians at will was already more valuable than a mountain of copper coins.
His intuition told him there was an unknown secret hidden here.
After all, why would a powerful witch risk injury just to find this flint?
Was it really just for gold coins?
Rod shook his head.
Although gold coins are valuable, they don't hold much allure for powerful witches.
It's like his situation now—he had countless ways to obtain more money than he could ever spend in a lifetime.
So why take risks?
With this thought in mind, Rod looked at the white dog in front of him.
"Take me to the treasure vault."
The dog's eyes flickered, as if it understood his words. It turned and began running toward the outskirts of the town.
Rod mounted his warhorse and quickly followed.
After riding for about half an hour, they arrived at a large, withered tree.
The white dog jumped towards the tree and disappeared.
Rod pulled out his whistle and gently blew on it. His Dark Night warhorse faded into the mist.
Walking up to the tree, Rod circled around it.
Finally, he found a tree hollow large enough for a person to enter among the weeds by the roots.
He jumped down, falling about ten meters before landing on the ground.
Shh! Shh! Shh!
An endless corridor lit up with torches one after another.
At the end of the corridor, three doors of different sizes came into view.
On the left was a bronze door, just big enough for one person to pass through.
In the center was a silver door, about four or five meters high.
On the right was a massive golden door, towering dozens of meters tall.
