Hughes' eyes lit up, and he sped up a little, advancing quickly along the direction where the demon beast's voice came from.

After walking for a few minutes, he saw the source of the demon beast's voice in the forest.

It was a huge iron-skinned pig, and beside its feet, there was a dying gale wolf.

The howl just now should have come from that gale wolf.

"Huff, huff."

The iron-skinned pig opened its mouth wide and directly bit at the gale wolf, starting to eat in large mouthfuls.

As it enjoyed the delicious food, it did not notice that Hughes was hiding behind the tall trees more than ten meters away

"It really is the iron-skinned pig."

Hughes smiled slightly and walked out from behind the trees with the flying tome.

Demon beasts had the ability to release magic.

However, this was only limited to the demonic beasts of some races, like this iron-skinned pig. Although it had the talent of earth elemental magic, it only had a huge body and thick skin.

Therefore, as long as it was a little careful, it did not have to worry that this demonic beast would hurt it.

"Roar!"

Noticing that a human was approaching, the iron-skinned pig immediately stopped eating. Its scarlet eyes stared at Hughes, who was not far away, and it directly launched an attack!

Rumble...

The running iron-skinned pig was like an armored vehicle that was traveling at high speed, and it directly crashed into the tall trees along the way!

In the blink of an eye, it was within a few meters of Hughes!

The iron-skinned pig's eyes were scarlet, and there was still the flesh of the gale wolf in its mouth. Coupled with its huge body, it looked incomparably ferocious and dangerous!

If an ordinary magician were to face it, they would definitely be so scared that they would not even have time to mobilize their mana!

However, after experiencing so many things, there was not even a hint of emotion in Hughes.

Just this? This was too useless!

He smiled slightly, waved his right hand, and the tome in the air began to turn its pages. Then, spots of golden light slowly floated out.

One sentence was heard, "Chained light arrows."

The golden light dots around instantly turned into a golden spear, and then shot toward the iron-skinned pig with a thunderous momentum!

"Roar!"

Sensing the dangerous aura on the golden spear, the iron-skinned pig, who was running, subconsciously stopped, and then let out a threatening roar!

Rumble...

The golden spear carried an indomitable aura as it struck the iron-skinned pig's most vulnerable abdomen. Then, an intense golden light burst out.

"Roar!"

The iron-skinned pig let out a shrill scream. Its entire body was burned by the temperature of the golden spear, and then it crashed to the ground!

"Ding, you have killed a high-level demon beast, iron-skinned pig. Obtained 20 mana points."

"Mana points!"

Hughes opened his attribute panel.

[Host: Hughes]

[Realm: high-level mage, (Low-level)]

[Magic attributes: Light Magic (SS), Dark Magic (SS)]

[Mana points: 55 points]

[Magic: Chained Light Arrow (control), light sword (low-level), blind (low-level)]

[Contracted Magic Beast: None]

[Magic Tool: Lorelei's Secret Tome]

"Sure enough, killing the demon beasts is the fastest way to become stronger!"

Hughes was delighted and said in his mind, "System, add all the mana points to your cultivation."

"The mana points are too low, you need more mana points to use."

The system's cold voice sounded.

"More mana points? That's easy. I'll just kill more monsters."

Hughes raised his eyebrows and walked forward, looking at the iron-skinned pig that had lost its breath.

The iron-skinned pig's skin was originally brown, but under the attack of Hughes's golden spear, its entire body had turned red.

Even the air was filled with the aroma of roasted meat.

"In the future, if all the demon beasts are eliminated, with my light magic, it should be pretty good to be a roasted meat master."

Hughes smiled slightly and crouched down, ready to collect his spoils of war.

The demon beasts that evolved under the influence of magic power not only had magic cores in their bodies, but their flesh and blood were also very beneficial to humans!

However, he had not planned to collect the flesh and blood. One reason was that the corpses of the demon beasts were too huge, and there was too much flesh and blood, so it was not easy to carry them.

Another reason was that it was forbidden to take away the flesh and blood of the demon beasts in this catacombs, and only the magic cores could be taken away.

Hughes guessed that this was probably because some of the flesh and blood of the demon beasts carried a virus, in order to prevent one from causing a plague.

The magic core of the gale wolf was very easy to harvest. After searching for a while, he found it.

The magic core of the iron-skinned pig was not easy to get.

Because it was killed with a golden spear, the entire body of the iron-skinned pig was very well preserved.

And the iron-skinned pig was a beast with rough skin and thick flesh. Hughes, who did not carry a knife with him, really had no idea where to start.

"Looks like I'll have to bring a sharper knife with me next time."

Hughes shook his head. He was not discouraged.

With a wave of his hand, more than ten golden spears formed and bombarded the iron-skinned pig.

Instantly, the smell of meat filled the air again.

After doing this many times, the iron-skinned pig's corpse was finally bombarded.

"Is this considered animal cruelty?"

Looking at the body of the iron-skinned pig, which was already riddled with holes, Hughes shook his head.

After being continuously burned, the entire body of the iron-skinned pig became a little crispy.

He only exerted a little force and reached into the belly of the iron-skinned pig. Then, he took out the yellow magic core.

"This is the magic core, the most valuable thing in the body of a demon beast."

Hughes carefully observed the two magic cores in his hands, one green and one yellow.

These two magic cores were extremely round, and they were still emitting a faint magic energy fluctuation.

According to the race, the size, type, and use of the magic cores in the body of a demon beast were also different.

Just like the yellow one of the iron-skinned pig, the slightly larger one was a high-level low-level earth magic core.

As for the gale wolf's green one, the slightly smaller one was a middle-level high-level wind magic core.

"A high-level low-level magic core can be sold for 40,000 to 50,000 dollars outside. The two in my hand now are worth 70,000 to 80,000 dollars outside, which is equivalent to the total income of an ordinary family in a year!"

Hughes played with the two magic cores in his hand and sighed inwardly.

In the past, because of the death of his parents, his monthly living expenses were only 1,000 dollars.

Now, after casually killing a demon beast, he already had several years' worth of living expenses!

However, he also knew that this was because he was a magician with the talent of SS-grade light magic.

If it were any other ordinary magician, this iron-skinned pig would basically require four magicians to work together to kill it!

"As expected, no matter where it is, the rare ones are always the best."

Hughes smiled slightly, placed the two magic cores into his backpack, and then left the second floor.

The smell of flesh and blood would attract other demon beasts, so he could not stay here any longer.
