Chapter 507: Race Against Time

Feng Jianxiu!

Zhan Nianchuan was shocked and immediately cast several spells, releasing all the power of the Thunder Stone that he could inspire.

For a moment, the silver-white arcs on the Demon-Slaying Formation kept jumping, and the rumbling thunder resounded throughout the inner abyss. The thick demonic energy that was rolling out retreated as if it had met its nemesis.

Taking advantage of this opportunity, Zhan Nianchuan looked extremely solemn, and cast spells with both hands in succession, causing the ground to suddenly tremble. Dozens of large cracks spread out like spider webs, and countless demonic energy entangled him like dancing long snakes.

These long tongues were all transformed from extremely pure demonic energy, and their power was far beyond the demonic energy diffused in the Demon Abyss. Zhan Nianchuan would never dare to let them entangle him.

However, there was nowhere to hide in this formation, and he had to use the spell to break the seal as soon as possible. In desperation, Zhan Nianchuan had to cast several spells in succession to transfer part of the thunder power on the demon-killing formation to himself.

Soon, the fine arcs on Zhan Nianchuan's body began to jump, interweaving into a thunder net, which completely eliminated the many demonic energy that attacked him.

"Human boy! Give me your life!"

A shocking roar came, and a thin black shadow waved both hands, and two huge claws tightly grasped a huge white bone that was more than ten feet long. With a whistling wind, it smashed Zhan Nianchuan in the formation.

"Boom!"

A shocking explosion sounded in the cave, and the surging mana fluctuations completely swept away the demonic energy within a hundred feet, and a huge vacuum zone appeared.

"What kind of formation is this?!"

Mo Qi exclaimed in disbelief.

He was a demon general in the middle stage of Naling, but in this demon cave, he used the endless demon energy here to launch a full-strength attack, but he couldn't break the magic circle.

Not only that, the thunder power attached to the magic circle actually consumed 30% of his magic power!

Just when Mo Qi was extremely surprised, Zhan Nianchuan also felt that the situation was extremely critical.

As he gradually broke the formation, the demon energy leaked from it became more and more dense, and the pressure on him became greater and greater. The thunder net on his body had a tendency to be unable to suppress it.

"Boom!"

Another violent shaking came, and Zhan Nianchuan's face became uglier.

Needless to say, it was the demon man outside who was bombarding the formation again, trying to prevent himself from breaking the formation under the white bone altar.

Although the power of the third-level demon-killing formation was strong enough, the previous killing of nearly a hundred Condensation Realm monsters had consumed most of the thunder and lightning power of the evil-repelling thunder wood. At this time, there was the wanton impact of pure demonic energy inside, and the full-strength attack of Demon Seven in the middle stage of Naling outside, and there was great pressure inside and outside.

When Zhan Nianchuan tried his best to break the formation below, he was completely unable to control it. The demon-killing formation was about to reach its limit and would soon be broken by the combined efforts of two powerful forces.

"Come on, let's see who moves faster!" Zhan Nianchuan's eyes were as sharp as lightning, and he cast dozens of spells again.

The ground shook violently again, countless cracks appeared, and the overwhelming demonic energy rushed out crazily, rushing towards Zhan Nianchuan, trying to drown him completely.

Seeing this, Demon Seven outside the formation was both happy and terrified. He held a huge white bone and bombarded the formation desperately, completely ignoring the fact that his body was already charred.

"Break it!"

Zhan Nianchuan roared, and the lightning net on his body shone brightly, and actually forced the dense demonic energy that seemed to be real back by a foot. Then he exhaled and spoke, and suddenly slapped the storage bag, and two black balls covered with silver-gray mysterious spiritual patterns flew up!

Seeing this scene, Mo Qi outside the formation roared with extreme anger:

"Breaking formation beads!"

This is a weapon that can break most of the third-level formations, and there are two of them!

The silver-gray spiritual patterns shone brightly, and countless runes merged into the silver-gray runes under the ground, making these runes dim instantly, and the operation of the entire formation suddenly stagnated.

The crazy surging demonic energy was reduced by more than half.

Zhan Nianchuan held the Burning Heaven Sword in his hand, and poured all his rolling magic power into it. He aimed at one of the places covered with a black mesh object, where the demonic energy was still emitting, and slashed it with a sword.

"Bang!"

Sparks flew everywhere, demonic energy surged, Zhan Nianchuan's full-strength attack was so powerful that even a million-jin boulder would be split in half, but it could not damage the black object at all.

"Hahaha~" Mo Qi, who was outside the formation, saw this scene and couldn't help laughing triumphantly, and then used his strength to bombard the formation.

Half of his body was filled with demonic energy, and the other half was jumping with arcs, which looked extremely weird.

"Idiot! This is the formation personally arranged by the envoy. Even if you find the center of the formation, what can you do with the soul-sealing net made of the Heavenly Demon Stone?" Mo Qi endured the pain of being bombarded by thunder and roared and cursed loudly.

Zhan Nianchuan frowned, his thoughts kept turning.

Heavenly Demon Stone? It seems that only by using the Thunder Tribulation Stone can there be hope to use the power of thunder to destroy this strange stone of the demon clan, but once the Thunder Tribulation Stone is used, the Demon-Slaying Formation will be destroyed instantly. No, it cannot be used.

Red Lotus Earth Fire?

No, this spiritual fire consumes too much mana. His current mana is less than half of his peak. If he uses it, he will not be able to fight at all. Moreover, Zhan Nianchuan has a strong feeling that even this heaven and earth spiritual fire comparable to the Danhai Realm fire of a fire spiritual root cultivator cannot destroy this so-called soul sealing net in a short time.

The roar of the attacking formation came from his ears. Zhan Nianchuan looked at the increasingly dim arcs of electricity on the Demon-Slaying Formation and the thick demonic energy that began to gradually emanate, and decided to take a risk.

He slapped his storage bag, and a palm-sized, black and transparent crystal flew out.

Outside the formation.

The always confident Mo Qi was stunned. He looked at this black and transparent sharp crystal, and muttered in disbelief:

"Demon Marrow Diamond?! Oh my God!"

Then Mo Qi, who reacted, suddenly hit his chest and spit out a mouthful of black blood, which sprayed on the formation.

As the blood was spit out, Mo Qi's breath instantly wilted, and the whole person looked exhausted. The lightning on the formation flashed wildly, and it dimmed at a speed visible to the naked eye after only a few breaths.

Demon Seven let out a sharp roar, and poured all his magic power into the huge bone magic weapon. At the same time, he raised his hand and threw out a black talisman with a hideous skull on it, and activated it with a bang.

A huge skull flew up, and with a strange laugh, it opened its mouth and sucked. The rich demonic energy within a range of thousands of feet around the Demon Abyss was immediately absorbed, and the whole skull doubled in size again!

Under the guidance of Demon Seven's divine thoughts, the skull was surrounded by white demonic flames, with a whistling wind, and turned into a silver-white lightning and fell down, aiming directly at the place where Demon Seven's essence and blood had been corroded before!

At the same time, Demon Seven also waved the huge bone magic weapon, and tried his best to smash it towards the temporary weakness of the Demon-Exterminating Array!

With this blow, he wanted to destroy the Zhan Nianchuan Array and kill people!
