The steel shovel hit the giant crab and made a sound like gold and iron colliding as it hit the hard shell. The steel shovel bounced back, causing Jackson's arms to feel numb. The giant crab seemed even angrier and reached one of its large claws through the door, trying to clamp down on Jackson.

Jackson quickly stepped back, making it impossible for the huge claw to reach him.

Harry released Olivia and activated the "Peeking Eye Rune" to observe the giant crab.

Immediately, a message appeared in his mind.

"Name: Behemoth Crab, elite breed among level 3 Spiritual Source beasts. The back shell is as hard as iron, and the abdomen is soft, which is its only weakness. There is a certain probability of obtaining the special skill 'Behemoth Armor' by killing a Behemoth Crab."

"It's a level 3 elite Spiritual Source beast, no wonder it's so terrifying." Harry took a deep breath and said, "This guy is called a Behemoth Crab, an elite breed among level 3 Spiritual Source beasts. The Leviathan Lizard we just encountered was only a regular level 3 Spiritual Source beast."

Now Harry knows that among Spiritual Source beasts of the same level, there are regular breeds and elite breeds. Elite breeds are much stronger than regular breeds, so Behemoth Crab can easily kill a same-level Leviathan Lizard.

What interested him the most was undoubtedly killing this Behemoth crab, which had a certain probability of comprehending a new special skill called "Behemoth Armor".

Jackson saw the fine vertical lines on Harry's forehead and became curious about his knowledge of these monsters.

Harry didn't hide it from him and told him it was called the "Peeking Eye Rune," just like his "Soul Devourer," it was also a special ability. Although it had no attack ability, it could peek at the basic information of these Spiritual Source beasts, and was very practical.

This Behemoth crab was limited in size and could not squeeze through the stairway entrance. It continued to extend one of its pincers inside.

Jackson held a steel shovel and hit it twice, but unfortunately, the pincers were too hard, like hitting steel, and could not harm the Behemoth crab. The Behemoth crab couldn't get in, so it couldn't harm them either.

"Let's go." After Harry learned about the Behemoth crab's information, he headed towards the stairs.

Seeing Harry go downstairs, Olivia followed closely behind, while Jackson cursed, "Don't think you're so tough just because you're a big crab. I'll stew you in a pot sooner or later."

He followed them downstairs while muttering.

The three of them went down the stairs, and Harry, who was in the front, was soon attacked.

The moonlight couldn't shine into the stairs, making it very dark inside. Although it wasn't pitch black, they could only see each other's blurry figures.

Olivia, who was following closely behind Harry, suddenly spoke up and warned him to be careful.

She had strengthened her eyesight once, and her vision was significantly better than Harry and Jackson's. Even in this darkness, she could see more clearly than the two of them.

Without her reminding him, Harry had already noticed a black figure rushing out from the corner of the stairs ahead of them. In this darkness, the face of this black figure was almost unrecognizable, but the "Peeking Eye Rune" prompted him that it was a Water Rat Beast.

Harry remained calm and swung his iron rod with both speed and strength, suppressing the Water Rat Beast in front of him.

"With a loud 'Bu', the Water Rat Beast's head was hit by the iron rod, immediately shattering its skull and falling heavily to the ground, killed in one blow.

A Spiritual Source appeared and entered Harry's mind.

"Level 2 Spiritweaver: Spiritual Source 14/20"

Harry gave up his fight with the Behemoth Crab on the rooftop, as he was more interested in this group of Water Rat Beasts.

These Water Rat Beasts were afraid of the Behemoth Crab and did not dare to charge onto the rooftop. Although they retreated, they did not run far away, but gathered in the staircase, ready to attack them at any time.

Water Rat Beasts were a common species among the second-level Spiritual Source beasts, and their strength was not particularly strong, making them the perfect target for Harry now.

Seeing Harry kill a Water Rat Beast that pounced from the darkness, Jackson also understood and let out a low laugh, carrying his steel shovel and surpassing Olivia in front of him, rushing down below.

Although Jackson was a Level 3 Spiritweaver, one level higher than the Water Rat Beast, he could still gain Spiritual Source by killing them. Of course, if he hunted a lower-level first-level Spiritual Source beast, the Spiritual Source gain would be minimal and almost negligible.

Between the stairs below, Water Rat Beasts kept charging towards them and biting.

Jackson let out a low roar and slammed the shovel down. Although the shovel was not particularly sharp, he hit the neck of the Water Rat Beast with force, and surprisingly, its head was chopped off.

"Good, only four more to go." Jackson became more excited, having gained a Spiritual Source.

At this moment, Harry also killed another Water Rat Beast, and his Spiritual Source increased to 15/20.

Olivia fell behind and could not participate for the time being, only watching the two slowly kill their way down the stairs.

A Water Rat Beast leaped into the air, and Jackson swung his shovel, hitting it in mid-air. The Water Rat Beast tumbled and fell into the darkness below.

Unfortunately, no Spiritual Source flew out, indicating that the Water Rat Beast was not killed.

Harry continued to smash the iron rod towards the darkness in front of him. With the sound of bones shattering, he smashed another Water Rat Beast's head and it tumbled down the stairs.

A message appeared in Harry's mind, informing him that his Spiritual Source had increased to 16/20, getting closer to the breakthrough. Harry was also excited.

Jackson roared, suddenly swinging his shovel horizontally, hitting the head of a Water Rat Beast from the side, exploding its head and gaining a Spiritual Source.

After previously hunting a Level 3 Leviathan Lizard, both Harry and Jackson seemed to find it easier to deal with this Level 2 common Water Rat Beast.

"Only three more to go!" Jackson shouted lowly, surpassing Harry and rushing down to where the Water Rat Beasts were. He then hit a Water Rat Beast's head with his shovel, gaining another Spiritual Source."

The Water Rat Beast's eyes rolled back and it fell silently. From its body, a white Spiritual Source shot out and entered Jackson's forehead.

"Watch out!" Suddenly, Harry saw something and quickly reminded Jackson. At the same time, a figure suddenly flashed out from the darkness around the corner of the corridor, and swung its right arm, grazing Jackson's chest.

Thanks to Harry's warning, Jackson became alert and instinctively stepped back. He felt a cold sensation in his chest and a sharp, piercing pain that made him let out a miserable scream.

Almost at the same moment, Harry rushed over, shouting in anger and swinging his iron rod.
