Bidding farewell to Qin Ming and the others, Lin Fan walked forward along the mountain range, and according to the topographic map, the place where the Iron Wolf Beast often haunted was near the lake in front.

After walking for half an hour, I saw a bush, and after passing through the bush, I finally came to a lake.

"The topographic map shows that the Iron Wolf Beast often comes to this lake to drink, so I just have to wait here."

Lin Fan hid in a big tree and observed the surroundings.

It didn't take long for an iron wolf beast to come to the river, ready to drink water.

The Iron Wolf Beast was covered in black fur all over its body, hard and harder than iron, and its huge body stepped on the ground, making a loud "boom" sound.

"Good chance!"

While the Iron Wolf Beast was drinking water, Lin Fan used his thunder spiritual power, quickly approached the back of the Iron Wolf Beast, and slashed out with one sword.

While!

Slashed the Iron Wolf Beast's body head-on, making a golden iron sound, and the power of thunder and lightning spread to the Iron Wolf Beast's body, but it did not break through its defenses, but only left a white mark on its body.

"It's so hard, harder than an ironclad cow."

Lin Fan was secretly shocked in his heart, he had used the Wind Sword Technique just now, and he couldn't break the defense.

"Roar!"

The Iron Wolf Beast felt a little paralyzed in its body, turned around, and quickly grabbed Lin Fan with its front paws.

Lin Fan directly used the Stacked Wave Knife Technique, and the long knife collided head-on with the wolf's claw.

Bang!

The sixfold stamina exploded, and the huge body of the Iron Wolf Beast was knocked out and fell directly into the water.

"Roar!"

The Iron Wolf Beast was completely enraged, jumped out of the lake, and frantically pounced on Lin Fan.

Lin Fan brandished his long knife and fought head-on with the Iron Wolf Beast.

"The Iron Wolf Beast is a good sparring partner."

Thinking of this, Lin Fan used his thunder spiritual power to the extreme, and the momentum on his body suddenly became stronger.

"Thunder!"

The body shot at the Iron Wolf Beast, and the long knife slashed out like thunder, passing over the Iron Wolf Beast, bringing a ray of thunder light.

Laugh at!

I saw that the huge body of the Iron Wolf Beast was directly broken into two, and the two bodies rushed forward for a distance before they fell to the ground with a bang.

"It's worthy of a ground-level sword technique, so powerful."

Lin Fan was overjoyed in his heart, the first form of the Thunder Sword Technique had such a strong power, and the power of the later styles must be even stronger.

【Achievement +70】

An Iron Wolf Beast provides 70 achievement points, and it seems that it is also a mid-level demon beast, and the strength of the Iron Wolf Beast is much stronger than that of the Green Wolf Beast.

Then Lin Fan came to the corpse of the iron wolf beast and cut open its heart to see if there was a demon core, but to his disappointment, there was no demon core, so he had to cut its fur and put it in the ring.

"The smell of blood here will soon attract a large number of demon beasts, so let's change the location."

The lake meandered for more than ten miles, and Lin Fan came to a shore again, hiding behind a big tree, waiting for the next iron wolf beast.

Soon, there was a loud "boom" sound, and I saw three iron wolf beasts coming to the lake.

Lin Fan pulled out his long knife again, rushed forward, and used a thunderous sword, quickly killing the three iron wolf beasts.

Then I rummaged through their corpses for a while, but there was still no demon core.

A day passed, Lin Fan killed dozens of iron wolf beasts, and finally found a demon core on an iron wolf beast, only to see that the demon core was dark all over, about the size of an egg, and quickly received the demon core into the ring.

It was getting late, and the forbidden place at night was too dangerous, even Lin Fan didn't dare to hunt demon beasts at night, so he found a cave, meditated and cultivated in it, and waited for dawn.

The next day, Lin Fan still came to the lake and continued to hunt the Iron Wolf Beast, feeling that his spiritual power was exhausted, he took the high-level Huiqi Pill, anyway, his physique could take the pill continuously.

On this day, he killed thirty Iron Wolf Beasts and obtained three demon cores.

For five days in a row, Lin Fan had been hunting the Iron Wolf Beast around here, and after these days of training, the first form of the Thunder Sword Technique had been completely mastered, and even the second and third forms had been practiced, but they were just a little bit behind.

"There are already 9 demon cores, and there is still one missing."

At this moment, a loud "boom" sound came, smoke and dust billowed in front of him, and a large group of iron wolf beasts came to the lake in a majestic manner.

I counted it, and there were more than 20 in total.

"So much! No matter, it's enough to kill these demon cores again. ”

Lin Fan directly killed him with a knife, and when he came up, he slashed an iron wolf beast with a thunderbolt and a knife.

When the group of Iron Wolf Beasts saw their companions being killed, they were furious at the same time, roaring and attacking Lin Fan.

Lin Fan's body moved, and he quickly retreated with a thunder light step, opening up a distance from them.

The thunder spiritual power continued to pour into the blade, and the thunder light on the long knife was so dense that it slashed out with a knife carrying the power of mad violence.

"Thunderbolt!"

More than a dozen purple sword qi surged out and shot at the iron wolf beast group in front of them.

"Whew!"

With a scream, more than a dozen Iron Wolf Beasts were hit by the purple sword qi, blood splattered, and they died on the spot.

The other Iron Wolf Beasts were too frightened to step forward when they saw more than a dozen of their companions being killed in an instant.

Lin Fan took this opportunity to use the Thunder Blade again, instantly killing the remaining Iron Wolf Beasts.

"It can emit invisible sword qi, which means that the second form of the Thunder Sword Technique has been practiced to the highest level."

Long-range attack methods such as sword qi, sword qi, spear mang, and fist gang can only be used at will after the spiritual energy in the body of the martial artist level is liquefied, but some ground-level martial arts can also be used when they are trained to an extremely high level.

After rummaging through the corpse of the Iron Wolf Beast for a while, he found a demon core, and the ten demon cores needed for this mission have been gathered.

Lin Fan began to count the harvest, these days he killed a total of about two hundred iron wolf beasts, a total of 14,000 achievement points, plus the 5,000 achievement points that killed the green wolf beasts, now the total achievement points have reached 24,200, but there is still a lot of way to break through to the next realm.

These days, a total of 15 high-grade Huiqi pills have been taken, and the consumption is not large.

"The harvest is not bad, it's time to go back."

Lin Fan left the lake and walked back, just as he passed through the woods, suddenly, he felt a strong sense of crisis.

I saw a golden light flash in the bushes on the right, and then I saw a giant wolf more than two meters high, quickly crashing towards him.

"So fast!"

It happened suddenly, and there was no time to dodge, so he immediately condensed the thunder spiritual power in his chest.

"Bang!"

Lin Fan only felt that a behemoth as hard as a diamond, carrying a frenzied force, hit his chest, and the two layers of defense of spiritual protection and iron cloth shirt collapsed instantly, and a mouthful of blood spurted out with a "poof", and he fell to the ground, already seriously injured.

Since practicing martial arts, he has never been so seriously injured.

"Careless."

Lin Fan saw that the giant wolf was dressed in gold, flashing with a dazzling golden light under the sunlight, full of hardness, and instantly recognized that it was a high-level demon beast golden light wolf.

"I didn't go to the territory of the Golden Light Wolf, could it be that I killed too much and lured it in?"

These thoughts flashed in his heart for only a moment, Lin Fan quickly stood up, urged the thunder light step to the extreme, turned around and ran, and took out a large handful of high-grade life-returning pills as he ran, without looking at them, and sent them directly to his mouth.

The medicinal power of more than a dozen Resurrection Pills instantly turned into vitality, repairing Lin Fan's body, and his body began to recover at a speed visible to the naked eye.

Seeing Lin Fan fleeing, the golden wolf roared, and his body chased after him like a golden light.
