In an instant, the newly gathered skeleton warriors fell in pieces like harvested crops, and they could not stop the intruders at all, and the most powerful counterattack was only to stuff the intruders' soles with bone chips.

Looking at everything in the Shadow Valley, Lin Li suddenly had a familiar feeling in his heart, and this feeling did not all come from the previous trials, but more from the undead realm in the spiral of the Seven Realms of Sky City. Since they are all places occupied by undead creatures, it seems that there are some similarities, right? Lin Li casually found an explanation, then put that feeling behind him and continued to watch the battle of the elite mage group.

The initial large number of skeleton warriors gathered did not stop the progress of the mage group in the slightest, and after this group of bone warriors was blasted into bone chips, those skeleton warriors who crawled up scattered were even more unable to have the slightest impact on the mage group, and even as soon as they emerged from the dirt, they were immediately blasted into debris by several magics.

However, in the Valley of Shadows, there are not only low-level undead creatures such as bone warriors. As the elite mage group deepened, a sharp cry finally came from the depths of the Shadow Valley, and with that somewhat piercing sound, black shadows rushed towards the mage group fiercely.

Vampires can be regarded as quite high-level existences among undead creatures, and levels ten to fifteen are their general strength, but it is not rare to break through level fifteen. Of course, if you want to break through the legendary level, it will be very difficult for vampires, Nophile is still able to break through by sucking dragon blood, and ordinary vampires will not have such treatment, and it is almost impossible to break through the legendary level naturally.

The dozens of vampires that suddenly appeared in front of him, although there were not many who broke through the fifteenth level, they were also a not weak force. However, the magicians of the elite mage group were unmoved, as if this group of vampires was no different from those rotten and fragile bone warriors in their eyes.

And the next facts have indeed proved this, in front of the elite mage group, the only difference between vampires and bone warriors is only flying in the sky. Under the powerful and dense magic attack, even the vampires who had already broken through the fifteenth level failed to break into the formation of the magicians, just like moths to the flames, letting out a terrible scream and falling to the ground.

Losing the hell bones that the bone warrior could control, the soul fire in his eyes pulsed, waving the bone staff in his hand, shooting the hellfire projectiles at the intruders, but they were all blocked by a layer of transparent magic protection, only stirring up slightly twisted ripples, and then instantly overwhelmed by the magic that counterattacked.

The Valley of the Shadows is a world of the undead, with an endless stream of undead creatures constantly attacking the invaders, and they don't have much to think about, completely unafraid of complete destruction. However, the difference in strength makes any struggle they have in vain, like a praying mantis in front of the carriage, and the end is only ruthlessly crushed by the wheels, but it can't stop the carriage for a moment.

The formation of the elite mage group was still so neat, there was no change from when they entered the Valley of Shadows, and everyone took the same steps, firmly moving towards the depths of the Valley of Shadows, sweeping through the places they passed. Whether it's a bone warrior, a vampire, a hell of bones, or any other undead creature, they're all completely destroyed by a storm of magical attacks, and they can't even survive in front of the mage group for a second longer.

However, the Shadow Valley has been able to exist in the hinterland of the Frang Kingdom for so many years, and it is not only this strength, otherwise this tumor-like existence would have been completely eliminated long ago. Finally, Orana's elite mage group came to a halt, for a true army of the undead had been gathered in front of them.

At the forefront of the line are still the eternal cannon fodder skeleton warriors of the undead, but these skeleton warriors are significantly stronger than those who crawled out of the mud. Although they are still the lowest-level undead creatures, every bone on the bodies of these skeletal warriors is so bright and shining, like a work of art carved from jade. The long swords held in the hands of the skeleton warriors were also bright and cold, as new as if they had just been taken off the forge table. Countless skeletal warriors are densely packed into the valley, making people feel their scalps tingle.

And above the head of the skeletal warrior, countless black shadows continued to hover, emitting a sharp and piercing cry, as if telling the thirst for blood. The mage group that swept all the way seemed to have become a delicious meal delivered to their door in their eyes.

"Roar!"

A soul-level roar sounded in the minds of the magicians of the mage group, and even caused them to have a brief trance, as if their souls were all shocked out of their bodies in this roar.

At the same time, the army of the undead also moved, and the skeletal warriors raised their swords and charged towards the mage regiment like a tidal wave. The vampires in the sky, turned into black lightning bolts, whistling towards the ranks of the mage group. And behind the bone warriors, the overwhelming fire bombs, bone spears, poisons, curses, and other kinds of undead magic swept towards the mage group like a storm.

A great battle broke out in an instant, this was the real battle, colorful magical light flickered endlessly, and the roar of magic explosions reverberated in the Valley of Shadows. This time it was definitely not as easy as before, whether it was the number or strength of those undead creatures, it made the magicians really feel the pressure.

Looking at the fierce battle below, even Odwin and Medellin, who were watching the battle, were slightly nervous, because this force was the pillar of the Orlana Magic Guild, because they knew that the appearance of the army of the undead meant that the master of the Valley of Shadows, the powerful undead monarch, had been awakened.

Lin Li could understand Odwin's nervousness, if it was his own team of the Tower of Twilight below, I am afraid that he would not be able to help but join the battle group. Because he knows very well that such a force that is famous in the Anriel Continent, the cultivation of every magician is extremely difficult, personal strength is one aspect, and more importantly, this kind of trust and tacit understanding with his companions, it is not that he has experienced countless tests of life and death, it is difficult to achieve the level they are now.

Under the impact of the endless army of undead, the formation of the mage regiment was not disrupted, but contracted more tightly, and layers of defensive magic shrouded the entire team, forming an impregnable fortress. Although the mage's progress stopped, it was still like a reef in the tide, standing still in the tide of undead creatures. The mages in charge of the attack in the team handed over their safety and security to their companions, and concentrated on a specific rhythm towards the surrounding army of undead, continuously splashing all kinds of attack magic.

Around the mage group, as countless magic flew out, countless undead creatures were blasted into pieces, forming a vacuum. But in the blink of an eye, more undead creatures arrived, filling the vacuum again. Countless magic flew out again, blasted out a vacuum, and then filled with undead creatures again, and the cycle repeatedly. The circle of the mage group is like a huge grinding disc, constantly crushing the undead creatures that come in.

However, this situation did not last long, and suddenly an extremely terrifying death force surged out from the depths of the Shadow Valley, and even these experienced magicians felt a palpitation inexplicably, and the operation of the entire formation also appeared to be delayed for a moment. Then, from the thick mist, a huge figure swept over the heads of the army of the undead, and pounced on the mage group surrounded by the undead creatures.

"Ignorant humans, you will have to pay for what you have done!" An angry roar rang out in the minds of all the magicians.

At this time, the magicians of the mage group saw clearly that the huge figure that had flown closer and closer was a real bone dragon. Before the mages could come to their senses, a dark green dragon's breath erupted from the bone dragon's mouth like a hurricane, enveloping the sky above the mages' heads.

However, the elite mage group of the Orlana Magic Guild can become a famous force in the Anriel Continent, but it is not only because they have excellent equipment, nor because of how good their personal strength is, what really gives them their current status is the combat quality that has been cultivated after countless life and death tests. They were in a trance for an instant because of the difference in strength, but after they came to their senses, although they knew the strength of the enemy, there was no trace of fear in their hearts, and some only had a strong fighting spirit.

The dragon's breath fell, and the layers of defensive magic broke instantly, if it was replaced by other teams, I am afraid that at this time, they would either scatter and flee, or close their eyes and wait for death. However, the magicians of the mage group did not have a trace of panic in their demeanor, and the layers of defensive magic quickly propped up. Eventually, the forty magicians unleashed legendary defensive magic through joint spellcasting, ending the attack of Dragon's Breath.

"Joint spellcasting, it seems that you have indeed spent a lot of energy on the cultivation of the mage group." Even the arbiter Megard, seeing the performance of the mage group, showed a rare amount of appreciation.

Although Odwin was still a little worried on his face, he couldn't help but show a hint of pride in his eyes after hearing Megeld's appreciation. Combined spell casting was one of the strongest means of the High Elf Magic Legion at the beginning, how many Flood Demonic Beasts whose strength was comparable to that of the Holy Domain, and how many Demon Monarchs who compared themselves to gods in the Endless Abyss were all defeated by the powerful magic jointly cast by the Magic Legion. This is not as simple as a few magicians casting spells together, allowing forty magicians to cast magic like one person, an extremely high tacit understanding is essential, and the fine control of magic output is even more demanding, and it is impossible to do it without thousands of practices.

However, the combined casting of a legendary defensive spell did not make the mage group truly invincible, as they were not facing an ordinary bone dragon, but the undead monarch of Shadow Valley. The mage group, which has been smooth sailing since entering the Valley of Shadows, has not fallen into the disadvantage even under the siege of the undead army, but at this time, it is really a little powerless in the face of the attack of the bone dragon.

Lin Li looked at the bone dragon hovering around the head of the mage group, and there was always a familiar feeling in his heart, the bone dragon that had become the undead monarch seemed to have only the bone dragon in the undead realm in the spiral of the seven realms in his memory. However, the bone dragon in front of him was obviously more than a little stronger than the one in the spiral of the Seven Realms, and I am afraid that its strength had reached the twenty-third level.

Just as Lin Li was observing the bone dragon, in the depths of the Shadow Valley, two powerful auras that were not weaker than the bone dragon erupted again. Lin Li couldn't help but be shocked in his heart, and looked behind the undead army with everyone watching the battle, only to see a lich wrapped in a robe and hidden under the hood, slowly flying from the depths of the valley, it was the Lich King among the three undead monarchs in the Valley of Shadows. And on the ground, the tall, giant-like Skeletron also walked towards the mage group step by step with heavy footsteps. In the Valley of Shadows, the legendary three undead monarchs finally all appeared at this moment.

If one is just a coincidence, what about three? Lin Li unconsciously touched his chin. The three undead monarchs in the Valley of Shadows are exactly the same as the three undead monarchs in the spiral of the Seven Realms, although there is a big gap in strength between the two, but it doesn't seem so convincing to say that they are completely unrelated.

Facing three legendary powerhouses with a strength of up to twenty-three levels at the same time, this is really completely beyond the ability of the mage group, although they have the ability to cast spells together, but they are not real legendary powerhouses after all. The lack of understanding of the power of the rules makes them much less powerful even if they use legendary magic.

The Lich King's realm of death enveloped the battlefield entirely, and those undead creatures that were originally vulnerable to the attack of magic erupted with far more powerful combat power than usual. A pitch-black gate opened out of thin air, and more undead creatures poured out, from low-level bone warriors to high-level vampires, infernal bones, and even a few bone dragons roaring out.

However, the magicians in the realm of death felt that their magic power had become much more difficult, and even their bodies had lost their original flexibility as if they were carrying boulders. The only thing that allows the magicians of the mage group to support is their superb combat quality and their incomparable tacit cooperation.

Skeletron followed and rushed forward, his massive double-edged sword, with infinite might, slashing at the mage's defensive magic. A crisp cracking sound sounded instantly, and the legendary defensive magic jointly cast by the magicians shattered like glass under the heavy blow of Skeletron.
