Soon the short day was covered by dark night, and Zhuang Yichen took Niuniu to the foot of a small barren mountain.

The vegetation on the mountain has withered, and not far from the foot of the mountain is a small village. On this small barren mountain, there lives a group of crypt spiders, and they are also the purpose of Zhuang Yichen's trip.

These crypt spiders hollowed out the interior of the small barren mountain and lived in it for a long time. As soon as Zhuang Yichen approached the huge hole at the foot of the hill, a fishy stench came to his nose.

Zhuang Yichen threw the entrails of the long-horned impala prepared in advance at the entrance of the cave, and then hid at the entrance of the cave and waited patiently. After a while, I saw a fishy wind blowing at the entrance of the cave, and a huge crypt spider was attracted by the smell of blood and rushed out of it.

The appearance of the Crypt Spider is indistinguishable from that of a normal tarantula, and it appears to be a tarantula enlarged to the size of an adult.

As soon as the crypt spider rushed out, Zhuang Yichen directly cast the white bone cage and blocked the hole behind it. This sudden change was immediately noticed by the crypt spider, which immediately raised the front half of its body, and its two sharp fangs were raised high, making a fighting posture.

Zhuang Yichen didn't dare to delay, and when the faint blue light in his hand flashed, a frost nova smashed directly over.

Just listened to the bang, the huge crypt spider was directly frozen by Zhuang Yichen's frost nova, at this time the movement of the fight at the entrance of the cave spread to the cave, and the huge hole mouth once again gushed out a fishy smell, and the sharp hiss continued to sound, and a large group of crypt spiders had rushed out.

The white bone cage at the entrance of the cave only lasted for a few seconds before it was corroded into a pitch-black slag by the venom from the crypt spider's spray.

Seeing this, Zhuang Yichen hurriedly threw out a large thick ice curtain to seal it at the entrance of the cave, and then an extremely cold impact swept towards the crypt spider that had just been released from the frozen state.

An ice-blue air current, visible to the naked eye, instantly swept through the entire fan-shaped space in front of it, and the crypt spider's body was immediately covered with a layer of white frost, and then its body became stiff.

All the vitality on its body dissipated under this wave of extreme cold impact, and when Zhuang Yichen saw this, he immediately cast a necromantic summon, and a long-legged spider with white bones appeared in front of him.

At this time, five crypt spiders had rushed out of the cave entrance, and among these five crypt spiders, there was a blood-red little leader. Zhuang Yichen immediately released more than a dozen Sinking Demon Skeletons from the necromantic space and rushed forward.

As soon as these Sinking Demon Skeletons approached the Crypt Spider, they directly exploded one after another, blasting their tight formation.

Swish!!

A demonic tentacle rose up, instantly binding the four ordinary crypt spiders in place, and Zhuang Yichen took advantage of this to focus on the blood-red little leader.

Sou~! A bundle of snow-white spider silk suddenly volleyed towards him, and Zhuang Yichen instantly opened the spell shield, allowing the bundle of spider silk led by the crypt spider to wrap himself tightly and pull it over at once.

The blood-red figure continued to enlarge in the eyes, and the bright red fluff on its body was also clearly visible. Just as it erected its sharp fangs and was about to stab into Zhuang Yichen's body, a violent explosion sounded instantly!

Boom~! Boom!! Boom! Elemental Blast!

In the continuous explosion, the body of the crypt spider was immediately or severely damaged, and it retreated uncontrollably, and the sticky spider silk was also blown to pieces.

At the same time, Zhuang Yichen waved his hand and smashed a large rain of corrosive arrows towards its body, and in a burst of tooth-souring sounds, its bright red body immediately became pitted.

Hiss!!

A blood-red venom gushed out from the two fangs of the tower, and Zhuang Yichen waved his hand to release a series of ice curtains, blocking the corrosive venom that was stronger than the corrosive arrow, and then three bone spears came out of his hand, forming a straight line, and accurately entered its mouthparts.

The Crypt Spider Leader was instantly pierced by three bone spurs, and twitched on the ground a few times, losing his movement. Zhuang Yichen swept his head and eliminated them with two waves of extreme cold shock, and then summoned the skeleton spider.

He expertly pulled out a blood-red magic crystal from the Crypt Spider Leader, then carefully cut off its poison sac, and quickly left the place.

Although Zhuang Yichen's realm has dropped to three stars, the magic he learned before can still be used, and although the magic power crystals of the fourth lesson are broken, the source of magic power that was expanded when he was promoted to the fourth order has not shrunk. At this time, the amount of magic power and tenacity in his body were more than twice that of an ordinary three-star mage.

There are thousands of crypt spiders in the depths of the cave, and Zhuang Yichen will kill the ones left at the entrance of the cave, and he will accept them when he sees it.

Strictly speaking, this is a barracks for the undead, specializing in the production of crypt spiders. Lower demonic creatures like the Sinking Demon, Crypt Spider, and Blade Demon all have the same way of reproducing.

And most importantly, their mother queen can directly convert the dark elemental into blood crystals to provide energy for the next generation when there is no food. This allows them to survive and reproduce even when they don't have food, and of course, if there is an abundant supply of food, the rate at which they reproduce and mature is even more terrifying.

Zhuang Yichen carefully observed that every month, a full hundred crypt spiders and five blood-red crypt spider commanders would be transferred out of this cave and transported to the battlefield mountain on the front line. It is precisely the existence of these low-level demonic creatures that makes the undead have an inexhaustible supply of soldiers.

After harvesting five crypt spider skeletons and a demon crystal of the leader, Zhuang Yichen couldn't help but feel good. He was going to store the Crypt Spider Lord's Magic Crystal first. After accumulating enough mana crystals, and then leaving the occupied area and entering the military's sphere of influence, and then re-entering the fourth order in one fell swoop, then there is no need to worry about the pursuit of the undead clan.

The night was dark, and after Zhuang Yichen finished solving the crypt spider, he returned to a hidden small cave that he had carved out. Although the Crypt Spider is of average strength, it has a natural magic talent and lurks.

After becoming a necromantic creature, this talent was also preserved intact. Back at his residence, Zhuang Yichen summoned five crypt spiders. I saw that with his order, the five crypt spiders flashed with earthy yellow brilliance, and burrowed into the deep soil layer under and around the cave, and there was no trace of abnormality on the outside.

This is also the purpose of Zhuang Yichen to summon them, with these crypt spiders lurking. In this dangerous wilderness, this cave is also more secure.
