As he spoke, the skeleton's figure continued to grow, and soon surpassed the height of the Sefalfa Castle, revealing a black-robed human body.

A large amount of magic pools were burning, and black energy was still pouring wildly into the massive form that had surpassed the Bethany giant.

As the magic pool was burned, the extreme blackness of the Phantom Star slowly faded at this moment, and the stars in the distance shone brightly, and the mud in the sewage pool reflected the stellar light in purple, casting the back of the giant skeleton in front of it, revealing an unusually large human silhouette.

This scene made the originally fiery battlefield instantly quiet, and Luo Lun felt his heart beat like a drum, he couldn't imagine that a black resentful spirit could use this method to increase its own strength to such a terrifying level.

"The whole army withdraws to the fortress!"

After a single command, all warships and land chariots, flying machines, golem warriors, etc., quickly returned to the Alchemy Fortress. At this time, the giant skeleton spirit had grown to a completely unimaginable height, and even in space beyond the Phantom Star, the skeleton spirit could be seen.

In the process of growth, the skeleton spirit was still roaring, and layers of fiery black qi rolled out from the open mouth, like a high-temperature flame of tens of thousands of degrees, and the black robe on his body also grew, and it was still draped on the skeleton spirit at this moment.

The army's retreat into the alchemy fortress was extremely fast, and it was only a matter of minutes later, before the skeleton spirit had stopped growing in size.

At this moment, the fortress was already very close to this huge skeleton spirit, so when the giant skeleton spirit opened its mouth again, a [Black Mist Arrow] with the thickness of a rocket shot out of its mouth, with a strong black flame on its tail, rolling up the air in all directions, and the momentum was amazing, heading straight for the alchemy fortress.

Outside the fortress, the powerful defensive membrane appeared a moment in advance, and the huge [Black Mist Arrow] was violently inserted into the defensive membrane, and the powerful vibration caused the powerful defensive membrane that enveloped the entire fortress in all directions to violently vibrate.

After a few seconds of stalemate, there was a crack, and cracks appeared in the defense film, but this rocket-like [Black Mist Arrow] had already exploded a moment in advance, turning into an overwhelming black venom paste on the surface of the defense film, and the originally transparent powerful defense film directly turned black.

The intelligent strain defense of the Erha system changed by itself, the outer defense film disintegrated directly, and the inner layer of the strong defense film immediately spread, replacing the position of the original defense film.

The giant skeleton spirit opened its mouth, and three thick [Black Mist Arrows] came, this guy was originally going to directly step out of his thighs hundreds of meters long and come to the alchemy fortress for a melee attack, but considering that he didn't know the details of the fortress, he couldn't help but didn't move.

The three [Black Mist Arrows] collided with the powerful defensive membrane one after another, but before that, the alchemy fortress rotated, and the defensive membrane was not attacked to the same position.

At the center of the fortress, five Bertany giants appeared, and at the moment when the defensive membrane was attacked for the second time, they danced the giant axe in their hands at the same time, and five equally powerful energies shook away the [Black Mist Arrow] that had not yet entered the defense.

Whoa......

Five more giant axes carried flames and scorched them, killing the giant skeleton spirit that was more than a thousand meters higher than the Bertany giant.

The energy of these five giant axes was originally extremely powerful, but at this moment, compared to the size of the skeleton spirit, it was like the slap of five children slapping an adult who was five big and three thick.

The skeleton spirit's right foot was raised, and the right foot that was as tall as a mountain slammed down, and the bottom of the sewage pool on the ground collapsed, and a strong wave of qi rolled up, destroying the five flying flame axe marks in an instant.

With another roar at the alchemy fortress, the skeleton spirit stepped forward with his left foot, and the entire huge figure moved forward, and the black robe covering the surface of the giant body was golden at this moment, and quickly condensed into a huge set of golden armor, forming a huge magnetic field on the surface.

Around the golden armor, a stream of terrifying pulses condensed, and the pulse vibration caused the surrounding air to fluctuate violently, and two slender black arms stretched out of the armor, which was the first time that the skeleton spirit showed his true body.

Between the thin fingers, it was as if pinching a ball of illusory air, and a large amount of black energy in the palm of his hand diffused and gathered, forming a huge black air mass.

A human-like figure flashed in the air mass, but it was actually a large number of ghosts, resentful spirits, and half-resentful spirits in the demon pool that had not yet had time to demonize. These negative energies have no consciousness, but involuntarily let out a miserable howl, which makes people get goosebumps.

Black Mass!

Countless negative energies were pinched together by the skeleton spirit and slammed in the direction of the alchemy fortress. At the same moment, a large number of pulsed streams outside his golden armor formed a strong bipolar magnetic field, and under the squeezing of life, an unprecedented stream of Gaussian pulses erupted, pushing the [Black Mass] air mass and crashing into the powerful defensive membrane of the alchemy fortress.

It's the perfect combination of dark magic and high-tech weapons!

No one would have imagined that in a high-level black resentful spirit, it would be able to condense the black spirit technique and technological weapons so seamlessly, making the attack power instantly multiply dozens of times!

It is said that this black resentful spirit has an abnormal talent and has created such a powerful attack move, and Luo Lun will not believe it if he is killed.

After seeing this, he was completely stunned for a few seconds.

A few seconds were enough time for the [Black Mass] blessed by Gaussian pulses to hit the powerful defense membrane, and with a bang, the powerful defense membrane collapsed instantly.

The reaction of the Erha system also reached an unparalleled speed, and it retreated sharply with full momentum a moment in advance, and the [Black Mass] still suffered nearly half of the loss after destroying the defense, but it was still like a bamboo, rushing horizontally.

At this time, the Alchemy Fortress opened the third-level state, that is, the mixed attack and defense state of spells and technological weapons.

All the magic circles were activated, and the super large attack circle was instantly stimulated, and with a bang, a huge lilac six-pointed star magic circle phantom catapulted out of the air, lying between the [Black Mass] and the fortress.

Hexagonal Purple Circle Defense Circle! This was condensed by Luo Lun using the only high-quality purple magic crystal he had refined today, and it was also his strongest defensive array.

The hexagon is the outer formation of the circle, and the more horns, the more powerful it is. Of course, if you have a black magic crystal, the hexagonal black circle formation will be more powerful in defense.

Luo Lun in the main control room suddenly woke up, immediately burned the essence blood, condensed a drop of golden alchemy blood, quickly crossed into the ghost cannon through the energy pattern, and used the high-speed operation of the magic circle as a pressure impact, and fired a super ghost cannon.

[Black Mass] collided with the hexagonal purple circle circle, and was forcibly intercepted by this super powerful circle, a large number of pulse ripples wandered inside and outside the circle, if it was an ordinary creature, it would have already disintegrated into particles under the powerful pulse flow, not to mention the black spirit effect of the mass.

However, the hexagonal purple circle circle was able to withstand the multiplier attack of this black spirit technique and high-tech weapons.

At this time, the super ghost cannon activated, and after a boom, the furious energy shot out of the cannon chamber with a drop of alchemy blood from Luo Lun, and instantly merged into the hexagonal purple circle circle.

The powerful energy that terrified the resentful spirits swept away, splitting the various negative energy impacts in the [Black Mass], and even if the pulse flow was maintained, it could not be condensed, and it was torn apart.

Wrapped in alchemy blood, the Super Ghost Cannon went straight to the head of the giant skeleton!
