As soon as the sandbag formation is formed, it can withstand the enemy's fierce attack, encircle their rear and repel their breakthrough. Victory is only a matter of time!

  Under the joint attack of the Warcraft army, the incoming Golems were knocked down one after another. Some were hit by the evil eye's petrifying magic, some were poisoned by spider venom, some were torn to pieces by hornets, and others were electrocuted into charcoal by unicorns. Of course, Yang Ling's talisman also played a crucial role.

  The great war was soon to come to an end. The ground and the walls of the cave were all splattered with blood, and from the entrance of the cave to the surrounding wall, a distance of only fifty or sixty steps, was piled high with the corpses of the stone statue demons.

  Commanding a team of horned beasts to patrol and stand guard outside the cave, Yang Ling quickly swept the battlefield. With his sharp dagger, he cut open the stone statue's skull, taking out crystal nuclei that were grayish-brown in color. Whenever he came across ones with all four limbs intact and still having some use, he would tame them by dripping blood on them one by one.

  Compared to the crystal cores of first or second tier low-level demon beasts, the stone statue's crystal core is much larger. Although it can't compare to the crystal cores of mid-to-high level demon beasts like the Thunderbird, it still contains a considerable amount of energy that can be used to set up some simple tracking arrays or spirit gathering arrays.

  Many of the stone statue demons were dead, but there were also quite a few that were severely injured and still twitching. After more than half an hour, Yang Ling had exhausted his last bit of magical power to tame over two hundred of them that still had some use value. Although they were all severely injured, he believed that as long as they stayed in the tower's space for a few days, they would recover to about 70-80%. At that time, he would have another excellent demon beast legion.

  Lightning-fast speed, sharp attack, fragile defense!

  Although he managed to defeat the incoming Golem with a single net, he still gained a deep understanding of the combat strength of these 4th-tier magical beasts.

  To some extent, these stone statues are similar to the cornered beasts. Their attacking power far surpasses their defensive capabilities. When encountering an enemy with insufficient combat strength, they may be able to quickly gain a great victory. But if they encounter a stable and steady opponent who is good at defense and has certain attacking abilities, they may not know what to do. They might even suffer a complete defeat.

  However, although somewhat similar, the Gargoyle also has its differences with the Hornet. Sharp and hard claws, combined with a half-meter long wingspan and great strength, make its frontal attack ability relatively prominent. But when it comes to stealth capabilities, these Gargoyles are no match for the Hornet, which is only fist-sized.

  Its small body, extremely high speed, and the venomous stinger that can be used to attack without warning make the Death Stinger one of the most formidable assassins. In a fair one-on-one fight, the Death Stinger is absolutely no match for the Golem; but if they were to suddenly meet in a narrow alleyway, a large group of Golems may not necessarily be able to defeat an equally sized group of Death Stingers that are all in top condition and armed with their venomous stingers.

  In general, the gap between high-ranking demons and low-ranking demons is quite obvious. When encountering a high-ranking demon, low-ranking creatures only have the option to flee. However, sometimes rank cannot explain everything!

  As long as you make good use of the timing and location, even low-level monsters have a chance to defeat high-level ones. The great victory in the bag battle has already explained everything. If you encounter a large group of stone statue ghosts ambushing in the open wilderness, Yang Ling, who had just fought a fierce battle with the wild evil eye, would be lucky to escape unscathed, let alone win a great victory.

  After sweeping away the remaining enemies, Yang Ling rode onto the Unicorn's back. He gathered up his demonic beast army and then rushed out of the cave like the wind, withdrawing while flipping through the memories of the Stone Statue Ghosts.

  Inside the basin, there are countless bottomless caves, and no one knows how many monsters are hidden. We must leave the bloody cave as quickly as possible. If the strong smell of blood attracts a large group of advanced magical beasts, we will be trapped inside and killed, and the consequences will be unbearable.

  According to the memories of the tamed Golems, they came from a cave five miles away, which is the closest Golem tribe to the Evil Eye Cave. Occasionally, they come out to hunt high-level Evil Eyes. Normally, they rarely appear in the basin, shouldering an ancient task, guarding an ancient sealed underground city.

  Sealed Underground Castle?

  A subterranean castle guarded by a multitude of dark creatures?

  Yang Ling was very surprised, and signaled for the unicorn to stop behind a remote small hillside, carefully searching through the stone statue's memories.

  The golems' memories of the dungeon itself were sketchy, but they had a lot of information about the magical creatures that guarded it. According to their memories, in addition to countless golems, there were many harpies, medusas and minotaurs and other mid-level magical creatures guarding the place. Even more, legend had it that at the deepest level, there were scorpion lions and black dragons standing guard.

  An underground castle guarded by a large number of high-ranking magical beasts. Is this really the giant dragon's relic that is said to have sealed away many undead divine artifacts?

  Yang Ling's heart moved, and he thought of the secret information that had been circulating in Visen Town recently. At first, rumors spread that someone had discovered a cave of ancient giant dragons deep in the Tras Forest, where many rare treasures were buried, attracting a large number of mercenaries and adventurers to flood into the remote Visen Town.

  Recently, through the thief Fenrist's grapevine, it was learned that someone had inadvertently discovered the ruins of the sacred giant dragon Elpazino's seal of the undead divine instrument, which is far from being as simple as the ancient giant dragon cave. Recently, a mysterious figure who has been sneaking into Visen Town one after another has confirmed this rumor from the opposite side, proving that it is not an unfounded rumor.

  According to the intelligence gathered by Good's parrot squad, these mysterious figures are different from ordinary mercenaries and adventurers. They either shut themselves in the Shangri-La Hotel, doing God-knows-what all day; or they nestle in the desolate mountains and forests, drilling in and out of the Trass Forest all day.

  Ordinary mercenaries and adventurers are extremely concerned about the situation in Weissen, from time to time cursing the airborne Lord Stoff, some even extending a black hand to the lone Black Armor Army. But those mysterious figures are different, they don't care about the situation in Weissen, and look down on the struggle between the Bandit people and the Ross people.

  After unexpectedly learning the news of the underground castle, Yang Ling thought for a moment and decided to sneak in quietly to take a look. Although he didn't know how powerful the so-called "Wraith Artifact" was, since there were so many magical beasts guarding it and people from all directions rushing over to fight for it, it was obviously some rare treasure.

  ******

  Time waits for no one, after making up his mind, he put away the unicorn and summoned a team of horned beasts to protect himself. Although the unicorn was powerful, the magic fluctuations it emitted were too strong, easily attracting the attention of magical creatures. This time, he only planned to do some preliminary exploration, if he wasn't careful and got surrounded by a large group of high-level magical creatures, it would be a loss.

  Going east all the way, after passing over a low shrub, Yang Ling arrived at the cave where the stone statue was hiding.

  The cave is very large, with rocks of various shapes scattered all over the place, as if it were a natural rock cavern. The further in you go, the more forks there are; without the memory of the stone statue, one would probably get dizzy and disoriented within just a few minutes.

  Perhaps the entire tribe had been wiped out, at first, no stone statues were encountered, but as they walked deeper, slowly, one or two patrolling guys appeared, and sometimes even met a dark sentinel leaning against the cave wall like a carving. Fortunately, the horned beast felt sensitive, otherwise, there would have been several times when their tracks were exposed. According to the memory of the tamed stone statue, they had already entered the territory of another group of stone statues.

  It's interesting, like a sculpture of a dark whistle!

  After witnessing the stone statue's ability, Yang Ling was moved in his heart. If he were to set up many such hidden sentries within the Visen Castle, he would definitely be able to make it impossible for any enemy who sneaked in to defend themselves. After all, not just anyone had senses as sharp as those of the hornet beast, nor did everyone have reflexes as quick as his own.

  In order to get as close as possible to the underground city, he carefully made his way along, using the scattered rocks everywhere to hide his tracks, narrowly avoiding the patrolling stone golems time and again.

  Beyond the territory of the stone statue, strange creatures with human heads and eagle bodies began to appear from time to time, floating in the air like a Siberian eagle. The sharp claws gleamed with cold light, and at a glance, it was clear that they were extremely sharp.

  According to the gargoyle's memory, these monsters in front of him are called Harpy, a 4th-tier demon beast. Although they are of the same level as the gargoyle, their defensive capabilities are much stronger, not only extremely fast, but also born with wind system acceleration magic. When necessary, they can consume magical power to shoot out and attack like a crossbow arrow, and then retreat in a flash before the enemy reacts.

  Unlike the stone statue demons, the eagle-bodied female demons had a more acute sense of feeling. As soon as Yang Ling entered their territory, a team of vigilant guys rushed over to carefully inspect him. Fortunately, there was a dark little cave on the nearby wall, and after drilling in, he narrowly escaped.

  Can't it be anything but abandoned halfway?

  Looking at the eagle-bodied female demon circling back and forth nearby, Yang Ling racked his brains but couldn't think of a way to sneak past quietly. Relying on the large army of magic beasts, killing these patrolling guys was no problem; but if they startled the other guards and brought in a large group of high-level magic beasts to attack, the consequences would be unthinkable.

  After a moment of contemplation, he still decided to give up. According to the gargoyle's memory, once past the harpy's territory, they would encounter fifth-tier minotaurs or medusas. If even the harpies were this troublesome, let alone the minotaurs and medusas that were a whole tier higher. Not to mention the higher-tier scorpion lions and black dragons behind them. Even if they managed to sneak in, whether they could get out was still a question.

  As long as the green hills remain, there's no need to worry about firewood!

  The Warenia Valley is rarely visited, and the possibility of ordinary people finding this cave and entering the underground city is even more unlikely. I don't have the ability to explore the underground city now, but that doesn't mean there won't be opportunities in the future.

  Yang Ling believed that as long as he advanced to the Earth Elementalist and condensed the Dan of the Witch, tamed more high-level magical beasts, there would come a day when he could return to the Valley of Valrenia, exploring the mysterious underground city. Perhaps, after obtaining what was known as the Undead Divine Artifact, he might be able to find a way back to Earth. Of course, if he could find a way to travel freely between this world and Earth, that would be even more wonderful.

  Under the guidance of the horned beast, relying on the dim light and agile body, Yang Ling safely avoided the patrolling eagle-bodied witches and stone statue ghosts, carefully exiting the vast cave.
