After the Blood Crow and the Dark Gold Demons all withdrew to the inside of the Purgatory Fortress, the entire fortress was immediately enveloped in a layer of dark red shield.

This is the powerful protective magic that the two demon gods have left behind for this fortified fortress, which can withstand any attack from the outside world and shield attackers from prying eyes inside the city.

After this layer of dark red shield was raised, the observation of the monitoring king insects in the city was immediately obscured, and the node king insects could not listen to any information in the city, and the entire purgatory fortress became a blind spot on the swarm monitoring map.

Faced with the demons' self-defense, Zagala had no choice but to prepare for a strong attack.

It brought the Kraken to this moment.

The insect tide quickly emptied the surrounding wilderness of the Purgatory Fortress, encircling the demons' last lonely city in the middle.

The roar of the Heavy Artillery Governor's cannon fire exploded in the sky again, and black fireballs and red streamers fell from the sky and smashed into the Infernal Fortress's shields.

Bang!!!

After a loud bang, the surface of the shield only fluctuated a few times, and it didn't mean to break at all, and it seemed that the two demon gods had put a lot of effort into this fortress at that time.

Two transcendental-level powerhouses appeared beside Xue Hua and told him that they could help the swarm.

But Xue Hua shook his head, saying that there was no need to be like this for the time being, the ferocious firepower bombardment of the insect swarm had just begun, and they also had time.

It is best for the two transcendents to wait until the transcendental-level demon in the city appears, and make a move now, which may allow the transcendental-level demon to find out the combat methods of the two of them, causing some adverse consequences.

Since Xue Hua insisted on this, the two transcendents no longer insisted, and from the Crazy Rift to here, the human alliance army fought endlessly along the way, and it was time to take a good rest.

After all, although they are all high-level professionals, they are not swarms after all, and they can't do continuous combat without sleep.

So a group of legendary powerhouses passed down the order, so that the major legions rested on the spot, recuperated their spirits, and were ready to participate in the siege at any time.

The major human legions encamped at the order and began to relieve the fatigue caused by the days of fighting, and the insect swarms that did not need to rest immediately began an all-round long-range bombardment of the Purgatory Fortress.

High in the sky, Kraken lifted its dormant state, and the tentacles of the continuous sky slowly stretched, quickly swimming to the sky above the Purgatory Fortress.

A few minutes later, countless acid spore bombs fell from the sky, slamming into the Infernal Fortress's shields, splashing green "splashes".

The acid in the acid spores quickly covered the entire shield, turning it from a dark red to a faint green.

These potent acid slurries were extremely corrosive, and soon a large amount of white smoke slowly rose from the shield.

However, even with this level of continuous blows, this shield imposed by the two demon gods themselves still appears to be very tough.

The acid caused it to slosh, but there was no sign that it was about to break.

As soon as the Kraken bombardment began, the other ranged units of the Swarm soon joined the artillery coverage.

The Hive Lord's Hive Raid is not very effective, as the shield prevents the Hive from invading the interior, so they can only gather outside the walls to gnaw on the shield.

However, the direct fire of the Heavy Artillery Governor is very good, every plasma shell can make the shield tremble, even the secondary artillery fire can make ripples on the shield, these destructive capital gunboats are rapidly weakening the shield's defenses.

Among the ground forces of the swarm, the Saboteurs, Spear Hunters, and Stinging Snakes all joined the onslaught on the shield.

However, unexpectedly, according to the observation of the Surveillance King Worm, among the firepower strikes of these three ranged troops, the Lance Hunter's bloodletting spear is the most effective, followed by the stinging snake equipped with armor-piercing spiny needles.

The worst of the effects are the usually powerful Saboteurs, whose scorching bile does little damage to the shield.

Based on this trait, Zagala removed the Poison Blaster Legion that had been intended to be used to bombard shields, and they had been the siege vanguard of the swarm, even more so since the advent of the Projector.

But since this shield seems to be resistant to strong acids, there is no need to make the Poison Blasters make unnecessary sacrifices.

However, Zagala applied to Xue Hua for Leviathan's secondary artillery fire support, and Xue Hua quickly agreed.

Using the Leviathan secondary cannon in the spiritual universe is no longer too much of a burden for Xue Hua now, so for the first time, he asked Isha to turn on all the secondary cannon firepower, and if he wants to play, he can play big.

Under Xue Hua's order, Leviathan's secondary cannon was quickly fully charged, but just as Xue Hua was about to tear open the dimensional door connecting his spiritual universe, he discovered a very strange thing.

Originally, when he used Leviathan's weapon system, except for Isha's Second Commander skill, the other weapon systems would deduct resources twice each time.

The first resource deduction is very small and almost negligible, according to Isha, this resource deduction is the real cost of charging the Leviathan weapon system, but the second resource deduction is very large, accounting for almost more than 95% of the entire Leviathan weapon system's use cost.

According to the adjutant's explanation, this part of the cost is used for Leviathan to break through the barrier between the spiritual universe and the worldly universe.

Xue Hua was already accustomed to this method of resource deduction, and realized that this was the price he had to pay when he carried a super biological mothership with him and wanted to use it.

But this time, when he tore open the dimensional door, although the second resource deduction still happened, the number of resources deducted was half less than before!

This means that with the same amount of resources, he will be able to unleash twice as many Leviathan weapon systems as before!

Just like this secondary salvo, he is now fully confident that he will be able to do another round after the bombardment!

"Isha, what's going on?"

Although this was a good thing, and Xue Hua probably guessed that it should be related to the changes in his spiritual universe not long ago, he still wanted to ask the reason.

"Your spiritual universe has undergone further changes during this time, and some energy and matter are being formed in the invisible mind.

It is moving closer to the form of the real universe, dominating, and this change will allow the Leviathan to synchronize the rules of the two universes, and the energy consumed when activating the weapon system to pass through the virtual and real barriers will naturally be reduced.

And the benefits of this change don't stop there, I'm sure you'll soon feel it yourself. ”

Isha gave him a brief explanation, letting Xue Hua understand that what he was going through now was not a bad thing.

"Okay, I got it." Xue Hua nodded, temporarily pressing down on his intention to explore the truth in his spiritual universe, and focused his attention on the Purgatory Fortress shield that was being ravaged by the Leviathan's secondary artillery fire.
