All evil eyes have evolved to the third stage, but unfortunately, selecting one of the strongest evil eyes and letting it continuously devour ten crystal nuclei still cannot evolve to the fourth stage, let alone evolve into a king like the wolf spider king.

  It seems that the difference between the fourth and third stages is not just a small step! Perhaps, only the crystal nucleus of high-level evil eyes can accelerate the evolution speed. Just like the Wolf Spider King, now swallowing ordinary spider nuclei has no obvious effect, and only swallowing spider nuclei of the same level or higher will have a greater impact.

  Since he had already infiltrated the Evil Eye settlement in the Valenia Mountains, Yang Ling couldn't bear to miss this opportunity and continued searching for a suitable target within the basin. Unfortunately, not to mention third-stage Evil Eyes, even naturally evolved second-stage ones were extremely rare, let alone fourth-stage Evil Eyes, which he hadn't seen any sign of after several days of searching.

  Inside the basin, caves are scattered all over, some are like rat nests with eight passages, and some are bottomless, walking for several hours without seeing the end. Dark and eerie, as if it were a bottomless pit leading to hell, although there are many magical beasts guarding his body, he dare not venture in carelessly.

  Apart from the evil eye and fire-breathing giant geckos, sometimes we also encounter some colorful, centipede-like long insects. Although their attack power is not great, their toxicity is even more severe than that of the wolf spider king. Fortunately, under the protection of the horned beast, we have been safe and sound for several days, and we can't find any high-level evil eye, but instead, we have obtained a dozen or so crystal nuclei from these centipedes.

  According to the evil eye's memory, this centipede is also a low-level demon beast that survives by swallowing a kind of green toxic algae growing in dark places. The longer its lifespan, the stronger the toxin inside its body, and those who are poisoned will suffer from boils all over their bodies if lightly poisoned, or rot to death if severely poisoned.

  Adhering to the principle of "it's better to err on the side of caution", Yang Ling would cut open the skull of each worm-like creature he killed with his dagger, and extract the dark green crystal core. Although it may not be useful for now, who knows when it might come in handy someday.

  At first, he wanted to tame a few more, but looking at their slow speed, he thought twice and gave up. The strength of the troops lies in quality rather than quantity, rapid mobility is indispensable, taming too many low-level magic beasts with slow speed will seriously drag down the mobility of the entire army, not worth it!

  That day, following a group of evil eyes that went out foraging for food, Yang Ling quietly arrived at a huge cave.

  Unlike the usual Evil Eye Caves, this entrance was guarded by a row of Evil Eyes. Moreover, there were several hidden sentries. Furthermore, the in-and-out traffic of Evil Eyes was endless.

  Isn't this an ultra-large underground cave of evil eyes?

  Watching the numerous evil eyes entering and exiting, Yang Ling's heart stirred, and he summoned a third-stage evolved Hornet Beast.

  The area around the cave entrance had grown a lot of dark green evergreen ivy, with lush branches and leaves that helped to block the view. A fist-sized horned beast quietly slipped in. Indeed, inside the cave was another world, with countless evil eyes of all sizes. Not only were there many second-level evil eyes, but also quite a few third-level ones.

  It's rare to encounter such a large-scale evil eye den, Yang Ling was excited, but looking at the heavily guarded evil eye, he couldn't help but frown. The covert whistle wasn't a problem, as long as a team of hornet beasts was dispatched, they could definitely take them out silently. However, with the evil eyes coming and going continuously, how could they take out the ones guarding the entrance without making a sound?

  Order the poisonous stinger of the horned beast to launch a surprise attack? Or command the wolf spider king to lead the spider army in a strong assault?

  After a moment of contemplation, Yang Ling gently shook his head. It's easy to deal with the evil eyes guarding the entrance, but the problem is that there are too many evil eyes coming and going. As long as they can't be caught off guard in an instant, the large number of evil eyes inside the cave may have to engage in a fierce battle after making sufficient preparations.

  The unevolved Evil Eye has slow speed, and its intelligence and attack power are severely insufficient. However, the Evil Eye that evolved to the second and third stages is different, with a certain level of intelligence and movement speed, although its defense hasn't changed much, but its attack power has increased by several times.

  In addition, if this cave has a Wolf Spider King-like evil eye king, the attack of the large group of high-level evil eyes is even more terrifying. Unless absolutely necessary, Yang Ling did not want to have a hard collision with his opponent, he did not want to kill one thousand enemies and lose eight hundred himself. No matter what time, getting the greatest benefit at the smallest cost is the king's way.

  Enemy Rear Garrison?

  Looking at the endless wild evil eyes, and thinking of his own evil eye army, Yang Ling's heart moved, and he thought of a wonderful idea. After gritting his teeth, he decided to take a gamble, and if it didn't work out, he would command his army to launch a strong attack.

  After directing a team of horned beasts to quickly dispose of the enemy's scouts, Yang Ling quietly summoned the demon beast army.

  Over 2,000 evil eyes were divided into ten groups, responsible for infiltrating the cave, and quickly taking out the enemy's elite after receiving the order to take action, while holding key passageways or high ground.

  The horned beasts are divided into five teams, responsible for long-range raids. As soon as the evil eye is in place, they must immediately solve the guardian of the cave entrance at the fastest speed and quickly rush in to support the weak defense of the evil eye.

  The Spider King's spider army is divided into ten teams, eight of which are responsible for closely following the actions of the Angle Worm Beast, and must quickly resolve the wild Yu Sheng Evil Eye in front of the cave entrance. The remaining two teams are responsible for acting with the Dry Wood Warrior to block the guys who are searching for food outside and rushing back to rescue them.

  Time waits for no one, after making arrangements, Yang Ling flipped over and rode onto the unicorn's back, commanding the Evil Eye to set off immediately.

  Perhaps the numerous passing evil eyes were too many, whether it was the passing evil eyes or the guards guarding the cave entrance, none of them noticed that several groups of strange evil eyes had quietly mixed into the cave. If they were a bit more careful, they would have discovered that this group of strange evil eyes had three tentacles on each side, all of which had evolved to the third stage.

  Unfortunately, none of the guards noticed this unusual situation, and Yang Ling's plan was successfully completed halfway. The careless Wild Evil Eye didn't know that an unprecedented disaster was about to befall!

  As Yang Ling's magical powers deepened, he could now control every single demonic beast within a five-mile radius with ease. Although the more precise the control and the longer the duration, the more magical power would be consumed, but it was still sufficient to cope with the current great battle. Under his command, the evil eyes that had infiltrated the cave occupied advantageous terrain one after another.

  After repeatedly confirming that the evil eye was in place, Yang Ling decisively commanded the remaining demon beasts to act. In an instant, the horned bee beast, which had been building up its strength, shot out like a supersonic fighter jet, charging straight at the wild evil eye guarding the cave entrance.

  A wave of dense venomous stings passed, and the army of tarantulas swept past the entrance without stopping. Under their lightning-fast raid, in front of their unstoppable venomous stings, not a single wild evil eye survived unscathed.

  Although unable to keep up with the speed of the cornered beast, the Wolf Spider King quickly commanded his army to act. Under its command, the phalanx of wolf spiders charged towards the Evil Eye Cave like a fierce tide, and the defenseless Evil Eye had no power to fight back.

  ******

  Commanding the remaining two teams of wolf spiders and withered warriors to form an array, leaving behind a blocking force to intercept the enemy's reinforcements, Yang Ling rode his unicorn to quickly catch up with the ferocious spider army. With these fearless spider soldiers, the powerful unicorn didn't even have a chance to take action.

  Inside the cave, the demonic beast coalition was unstoppable. A few high-level wild evil eyes had just gathered a group of low-level evil eyes to counterattack, and immediately received the focused attack of the hornet beast. Under the situation where the dragon has no leader, the low-level evil eyes with low intelligence fled in disarray, and fundamentally failed to exert the advantage of their large numbers.

  Faced with the pincer movement of Yang Ling's demonic beast army, faced with their fierce aerial and ground joint attack, the defenseless wild Evil Eye was defeated. Moreover, the guy who rushed back to rescue also suffered a fierce interception, just like a moth that flew head-on into a blazing torch.

  As a result, without any suspense, Yang Ling soon grasped the situation! The cave was filled with the corpses of wild evil eyes everywhere, and the depression in the center of the cave was like a blood pool filled with fresh blood. The air was filled with a strong bloody smell.

  According to preliminary statistics, nearly 5,000 evil eyes were annihilated in this battle. Among them, more than 200 had evolved to the third stage, and more than 800 had evolved to the second stage. Unfortunately, there were no evil eyes that had evolved to the fourth stage, nor was there a king like the Wolf Spider King.

  It seems there's no other way but this one!

  Since such a large-scale evil eye tribe doesn't have a true king, Yang Ling no longer holds any hope for this basin. Wanting to quickly obtain an evil eye king like the Wolf Spider King, it seems he can only take matters into his own hands.

  Time waits for no one, after commanding the demonic beast army to guard the entrance of the cave, he set up a simple soul-gathering array inside the cave and prepared to forcibly cultivate an evil eye king using his witchcraft power and life energy.

  The situation in Visen Town is delicate, and after staying in the Tras Forest for so long, I don't know what the current situation is like. Whether this experiment succeeds or not, we must return as soon as possible. After all, if the experiment fails, we can try again, but if Stov, that parachuted lord, successfully establishes himself, our future development will be greatly restricted.

  He picked out the strongest Evil Eye, sat down with his legs crossed, and gently pressed his right hand onto its forehead. Surrounding him were piles of large and small Evil Eye crystal nuclei. All or nothing, he decided to take a gamble, commanding the Evil Eye in front of him to continuously devour the crystal nuclei, while he himself continuously inputted crimson magical power and green life energy, gradually increasing the intensity.

  Under the multiple effects of crystal nucleus, witchcraft and life energy, the evil eye lying in front of Yang Ling trembled slightly, its muscles and tentacles constantly expanding, contracting, then expanding again, contracting again, circulating non-stop...

  At the same time, under the effect of the Spirit Gathering Array, the spiritual energy of heaven and earth surged in like a tide. Although it was far inferior to other places in the Tras Forest, it was still quite impressive. If one looked closely, they could see the corpses of wild Evil Eyes and the fresh blood in the Blood Pool emitting strands of crimson gas that quickly seeped into the Evil Eye's forehead.
