In the next few days, Zhuang Yichen would go to the cave of the crypt spiders on time every day, use bait to attract a small group of crypt spiders patrolling the upper layer of the cave, and then turn them into his skeleton brothers.

In half a month, Zhuang Yichen received a total of more than 20 crypt spider skeletons and five magic crystals led by crypt spiders.

With these gains, he immediately left the area. The number of soldiers produced by the Crypt Spider Cave every month is constant, which makes Zhuang Yichen toss like this. There are already just over sixty crypt spiders delivered to the front line this month.

As soon as the number of people here decreased, the undead immediately sent the harpy to investigate. Before Zhuang Yichen and Niuniu walked out of this small barren mountain, more than a dozen harpy banshees had already rushed over from the sky.

Zhuang Yichen immediately took Niuniu and fell to the ground on the spot, and then took out a pre-prepared camouflage net from the storage space and draped it on his body.

He used the Tower of Necrons to shield himself and Niu Niu's breath, and the harpy flew over their heads without noticing, and then patrolled around the crypt spider for more than ten miles, but found nothing.

After the harpy banshee left unwillingly, Zhuang Yichen got up, quietly used his flying technique, and chased in the direction where the harpy banshee left.

The Harpy is a quick reaction force deployed by the undead in the Fallen Zone, and if there is any unusual movement in the wilderness, they are the first to come to investigate. And Zhuang Yichen has been coveting such a swift air flight unit for a long time. Since the Crypt Spider, he has secretly plotted against the Harpy.

It didn't take long for Zhuang Yichen to chase down one of the harpy's lair. The nest was built in a large withered wood, with a dark red, heart-like brood beating in the center. It's like life. And the harpy hatched from the huge eggs that were born from it.

The harpies surround the nest and occupy the entire forest, and the figures of the harpies are everywhere on the trees, on the ground, and everywhere that is visible to the naked eye.

Zhuang Yichen came to the vicinity of the lair, first carefully probed, and then summoned all his crypt spider skeletons in a small narrow open area on the periphery of the lair.

A large number of white skeleton spiders appeared in the clearing, and then directly activated their innate abilities under Zhuang Yichen's order and lurked.

The earthy yellow light flickered, and all the crypt spiders dived underground. From the ground, there is still nothing unusual here. After the ambush, Zhuang Yichen came to the lair of the harpy, and directly revealed his body with a big grin, and a sharp bone spear flew towards the woods!

This time he immediately stabbed open the hornet's nest, and a team of a total of twelve harpy banshees immediately screamed and chased after Zhuang Yichen. Zhuang Yichen used his flying skills and sped away to the ambush location that had been set up in advance.

The Harpy's flight speed is very fast, coupled with Zhuang Yichen's deliberate control. Soon they roared angrily and came behind Zhuang Yichen.

They attack with only their own sharp claws, and do not have any ranged magic. The two harpy banshees at the front came behind Zhuang Yichen, screaming in their mouths, suddenly pulling up their figures, and screaming towards Zhuang Yichen.

The pitch-black and hard claws were only a dozen centimeters away from Zhuang Yichen's back, and he saw that Zhuang Yichen was about to be torn into pieces by this giant claw. However, at this moment, a mutation protruded!

A burst of earthy yellow light suddenly shone on the flat ground, and huge white cobwebs swept densely from below, directly pulling the twelve harpies to the ground.

The white webs were covered with a thick slime, and the harpy's huge wings were covered in feathers, which became the perfect bonding material. The invisible banshees screamed and struggled, but the harder they struggled, the stronger they became!

At this time, Zhuang Yichen had a smug smile on his face, and his momentum changed greatly, only to see him standing in the air, and the dark elements in the entire space instantly became violent.

Elemental boiling!

…… Boom~! Boom~~! Boom!! Boom!

A dense explosion sounded instantly, and a cloud of black mist burst out of thin air, and those harpy banshees who were bound in the cobwebs were instantly hit hard, and were seriously injured on the spot by the explosions that rose one after another!

At the same time, taking advantage of the moment when those harpies were injured and unable to resist, the crypt spider immediately injected a mouthful of black and foul-smelling venom into the body of the harpy.

…… Yes!!! Yes~!! Yes!

There was a burst of screams, and after a while, the harpy on the ground gradually lost its movement. Poison and elemental boiling damage piled up, ending their lives in a short period of time.

Zhuang Yichen did not waste time, quickly cleaned up the battlefield, and soon twelve harpy skeletons appeared in front of Zhuang Yichen.

Next, he concocted the same method, and continued to attract two waves of harpies out, and then used the pre-prepared ambush to kill them. At this time, the forces in his hands had reached twenty-five Crypt Spider Skeletons and twenty-four Invisible Banshee Skeletons. Such a wave of troops is enough for a large vote!

Just when he repeated his old trick for the third time, Zhuang Yichen ushered in the big guy as he wished. This time, the harpy came out of thirty at once, and one harpy demon emperor also flew out.

The Eagle Demon Emperor is a small commander-level monster, and its size is more enchanting than that of ordinary Eagle Banshee, and it is also larger. The biggest difference between it and a normal Harpy is the color of her hair. The other Harpys all have ordinary black and brown hair, but only the Harpy Demon Emperor is a bright orange color.

As soon as the harpy came out, Zhuang Yichen directly used his flying skills with all his strength, and brought them all the way away from the nest, and then he made a brazen move!

I saw that a large net instantly caught more than half of the harpy, and the remaining twenty-four harpy skeletons also took the opportunity to rush up and drag the other ordinary banshees.

As soon as Zhuang Yichen appeared in the cobweb, he instantly condensed a sharp bone spear and shot straight towards the eagle-body demon emperor!

The Eagle Demon Emperor screamed in his mouth, crushed the claw with one claw, and then stretched out his long scarlet tongue and licked his lips, bewitching and cruel.

After it crushed the bone spear at will, it turned out to be two huge eagle wings that flashed violently, and bursts of violent wind magic elements instantly condensed two slender tornadoes, whistling towards Zhuang Yichen!
