King Jin Tai took a heavy breath, he was still puzzled, why was this No. 22 Black Palace several times larger than the No. 12 Black Palace? Now he finally had an answer.

"It seems that in this underground palace, there are different numbered black palaces, and the difficulty of the test of the spirit beasts is also very different. The closer you get to the inner palace, the more difficult the test becomes, but the higher the level of the secret key provided, and the more useful it will be," King Jin Tai's face changed, "However, the old man's purpose is not to search for treasures, but to kill Xu Yang's thief as soon as possible! I don't know if he is still in the twenty-first black palace now? ”

King Jin Tai put away the two-star key, this thing could not be stored in the storage ring, he could only store it in a leather bag.

Raising his feet and stepping into the light gate on the west side, King Jin Tai stepped into the twenty-first black palace where Xu Yang was before.

The twenty-first black palace is empty, only a statue of a purple feather golden eagle, standing in place.

"Damn, has that kid already killed the spirit beast and gone deeper?" King Jin Tai's eyebrows furrowed deeply, his fists clenched to death, and he hated it in his heart.

The statue of the purple feather golden eagle of the "Kara ......" produced cracks one after another, and then burst out! A golden eagle spirit bird inside looked up to the sky and chirped, and the electric arc crackled and flickered!

"Damn!" King Jin Tai scolded, he suddenly remembered that he hadn't broken through the twenty-first black palace before, and now he entered rashly, of course, he would be tested by the twenty-one black palace! That is to say, he still had to kill this purple feather golden eagle before he could go to other palaces and find Xu Yang!

But the only thing that made King Jin Tai happy was that this purple feather golden eagle was in the Black Palace and could not fly. The strength is discounted.

"Xu Yang, when the old man catches you, he must cramp and peel you!" King Jin Tai swore again, and at the same time gritted his teeth to meet the thunder and lightning light net shot out by the purple feather golden eagle!

Black Palace No. 23, a fierce battle is underway!

A black-robed Hades World Venerable with a stern complexion. Fighting against a horse-shaped spirit animal!

This horse-shaped spirit beast has a majestic physique, and every inch of its body is an extremely perfect line, full of a sense of power! Its whole body is iron-gray, and it unexpectedly flashes a metallic luster. The most bizarre thing is that this horse-shaped spirit beast has eight long legs and gallops like the wind!

And this twenty-third Black Palace. It is already the second layer of the underground palace, and its length and width reach thousands of zhang! Although it is still a little narrow for the world-honored powerhouse, it is enough for this eight-legged horse to gallop.

With a flash of golden light, Xu Yang's figure appeared in this battlefield!

"Huh?" The black-robed Underworld Venerable was taken aback for a moment, and he ejected back, taking a defensive posture! The World Venerable of the Underworld was even more stunned!

"Xu Yang, how did you get here?" the elder of the underworld. The eyes were full of wariness and hostility.

"Hehe, I fell from the sky," Xu Yang said with a smile, "Which elder of the underworld are you, please ask for the name of Gao?"

"Old man Mingchang!" said the Lord Mingchang through gritted teeth.

You know, when the Immortal Lord was talking to Xu Yang. The spirit beast steed without wisdom did not stop attacking, and kept rushing back and forth, and the vigorous hooves of the horse kept trampling on the Immortal Chang Shizun, making him extremely wolf.

"Eight-legged iron horse?" Xu Yang's eyes lit up. said with a smile, "This spirit beast is not easy to deal with, Shenchang Shizun, your strength is full of calculations, and it will be the peak of a catastrophe, and it is not easy to survive until now." As far as I know, you Hades World-Honored Ones have a few World-Honored Corpses with you! Why, didn't you summon the Refining Corpses to help?"

"Xu Yang, you don't want to say cool things here!" said in the heart of the Immortal Chang Shizun, "Do you know the reason why I didn't summon the corpse refiner? There is a rule in this underground palace, that is, the more people who participate in the battle, the strength of the spirit beast will also double! Big deal, the old man summoned the corpse refining to join the battle, so that the strength of this spirit beast skyrocketed several times, after it killed me, the next target must be you." The old man wants to see if you can resist the attack of the eight-legged iron horse whose strength has increased several times?"

"I see!" Xu Yang's eyes flashed, and he said with a smile, "It's really funny that your Hades World-Honored Corpse Refining Corpse is actually a human being." You don't have to be impatient, I have an idea...... Why don't you and I work together to destroy this eight-legged iron horse?" He has never participated in the battle, so the strength of the eight-legged iron horse has not doubled.

"How do you want to cooperate?" Immortal Shizun took a breath, and the mystical power of the Underworld converged, turning into a large gray shield, and once again stood up to the eight-legged iron horse's pedaling, and his body exploded back dozens of feet.

"It's very simple, you drag this big guy, I'll prepare the occult arts, kill it with one blow, and don't give it time to double its strength!" Xu Yang said, "After my occult move, even if its strength increases, it will be impossible to dodge." ”

"This ......" Shen Chang Shizun was a little moved, but he still held a strong guard against Xu Yang, "How can the old man know whether what you said is true or false?

Xu Yang shrugged his shoulders and smiled: "You don't believe me." Then I'll watch from the wall, and wait until you are trampled to death by the eight-legged iron horse, and then I can make a move. ”

"You ......" Immortal World Venerable was discouraged, so he had to say, "So, how will the secret key of the eight-legged iron horse be distributed after its death?"

"Distribution?" Xu Yang said, "No matter how it is distributed, it is not appropriate to give a secret key to anyone, especially the opposition between you and me! ”

"Okay, a word is a certainty!" In the heart of the Immortal Chang Shizun, he had a small calculation.

At that moment, the eight-legged iron horse collided again, and the steel-like body slammed into the Xuan Power of the Immortal World Venerable's protective body, knocking it apart! The Immortal World Venerable only had time to blast a backhand punch, smashing into the chest of the eight-legged iron horse, sending out a buzzing sound of gold and iron.

This spirit beast is known as the eight-legged iron horse, and it really deserves the word "iron", and its strong defense is outrageous. The punch of the Immortal World Venerable, even if it is the Second Tribulation World Venerable, does not dare to bear it in the flesh. But this eight-legged iron horse, with a hard punch, is nothing at all.

With a bang, the body of the Immortal Lord was knocked into the air again.

"Xu Yang, you still don't make a move?" said the Immortal Lord as he flew in mid-air, shouting in pain.

Xu Yangqiang couldn't hold back a smile: "It's coming, it's coming!" The defensive capabilities of this eight-legged iron horse are somewhat beyond my estimate, so the time to build up momentum needs to be extended. Immortal World Venerable, you have to hold on. (To be continued......)
