After Xuewu and all the dark gold demons all retreated into the Purgatory Fortress, the entire fortress was immediately shrouded in a dark red shield.
This is the powerful protective magic left by the two demon gods for this solid fortress. It can withstand any attack from the outside world and shield attackers from prying into the city.
After this dark red shield was raised, the surveillance king insects' observation of the city was immediately blocked, and the node king insects were unable to monitor any information in the city. The entire Purgatory Fortress became a blind spot on the insect swarm surveillance map.
.
Faced with the demons' defense of the city behind closed doors, Zagara had no other choice but to prepare for a strong attack.
It called Kraken just for this moment.
The insect tide quickly cleared the wilderness around Purgatory Fortress, surrounding this last lone city of demons in the middle.
The roar of the heavy artillery governor's artillery fire exploded in the sky again, and clusters of black fireballs and red streamers fell from high altitudes and slammed into the shield of Purgatory Fortress.
Boom!!!
After a series of loud noises, the surface of the shield only fluctuated a few times, with no intention of breaking. It seemed that the two demon gods put a lot of effort into this fortress at that time.
Two extraordinary powerhouses appeared next to Xue Hua and told him that they could help the insect swarm.
But Xue Hua shook his head and said that it didn't have to be like this for the time being. The ferocious fire bombardment of the insect swarm had just begun, and they also had plenty of time.
It would be best for the two extraordinary beings to wait until the extraordinary demon appears in the city before taking action. If they take action now, the extraordinary demon may be able to detect their fighting methods, causing some adverse consequences.
Since Xue Hua insists on this, the two extraordinary beings no longer insist. Moreover, from the Mad Rift to here, the human coalition has been fighting endlessly, so it is time to take a good rest.
After all, although they are all high-level professionals, they are not a swarm of insects after all, and they cannot continue to fight without sleep.
So a group of legendary strongmen passed down the order to let all the legions rest on the spot, recuperate their spirits, and be ready to participate in the siege at any time.
The major human legions set up camp according to the order and began to relieve the fatigue caused by the consecutive days of fighting. The insect swarm, which did not need to rest, immediately began an all-round long-range bombing of the Purgatory Fortress.
High in the sky, Kraken released his dormant state, and the tentacles stretching across the sky slowly stretched out and quickly moved over the Purgatory Fortress.
A few minutes later, countless acid spore bombs fell from the sky, hitting the shield of Purgatory Fortress one after another, splashing green "splash" in patches.
The acid in the acid spores quickly covered the entire shield, dyeing the shield from dark red to light green.
These powerful physalis are extremely corrosive, and soon, a large amount of white smoke will slowly rise from the shield.
However, even after receiving such a level of continuous blows, the shield personally imposed by the two demon gods still appeared to be very tough.
The acid erosion caused it to sway continuously, but there was no sign that it was about to break.
After the bombardment of Kraken began, other long-range units of the swarm quickly joined the artillery coverage.
The brood lord's brood raid is not very effective. This shield prevents the brood from invading the interior, so they can only gather outside the city wall and gnaw at the shield.
However, the direct damage firepower of the Heavy Artillery Governor is very effective. Each plasma cannon shell can make the shield tremble. Even the firepower of the secondary battery can cause ripples on the shield. These destructive main gunships
The shield's defensive power is rapidly being weakened.
Among the swarm's ground forces, saboteurs, spear hunters, and hydralisks all joined in the onslaught against the shield.
However, unexpectedly, according to the observation of the Supervisory King Insect, among the fire strikes of these three types of long-range arms, the Bloodletting Thorn Spear of the Spear Hunter is the most effective, followed by the Hydralisk equipped with the armor-piercing Thorn Spear.
The least effective ones are the Destroyers, which have always had strong firepower. Their burning bile does not cause obvious erosion damage to the shield.
Based on this characteristic, Zagara removed the Baneling Legion that was originally intended to bombard the shield. They had always been the vanguard of the swarm's siege, especially since the projectors were introduced.
But since this shield seems to be resistant to strong acid, there is no need for the poisonous banelings to make unnecessary sacrifices.
However, Zagara applied to Xue Hua for Leviathan's secondary artillery fire support, and Xue Hua quickly agreed.
Using the Leviathan secondary artillery in the spiritual universe is no longer a big burden for Xue Hua, so for the first time he asked Isha to activate all the secondary artillery firepower, and use the big ones if he wanted to use it.
Under Xue Hua's order, all Leviathan's secondary guns were quickly charged. However, 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 Isa's second commander skill, other weapon systems would deduct resources twice each time.
The first resource deduction is very small and can be ignored. According to Isa, this resource deduction is the real cost of charging the Leviathan weapon system, but the second resource deduction is very large, accounting for almost the entire
The Leviathan weapon system uses more than 95% of the cost.
According to the adjutant's explanation, this part of the fee is used for Leviathan to break through the barrier between the spiritual universe and the physical 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, after he tore open the dimensional door, although the second resource deduction still occurred, the amount of resources deducted was half as much as before!
This means that with the same amount of resources, he can release twice as many Leviathan weapon systems as before!
Just like this secondary gun salvo, he now has the confidence to fire another round after one round!
"Isa, what's going on?"
Although this was a good thing, and Xue Hua probably guessed that it was related to the changes in his spiritual universe not long ago, he still wanted to find out the reason.
"Your spiritual universe has undergone further changes during this period, and some energy and matter are being formed in invisible thoughts.
It is moving closer to the form of the real universe, Master. This change will allow 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 believe you will feel it soon.”
Isha briefly explained to him, letting Xue Hua understand that what he was going through now was not a bad thing.
"Okay, I understand." Xue Hua nodded, temporarily suppressing his intention to find out what was going on in his spiritual universe, and focused his attention on the shield of Purgatory Fortress that was being ravaged by the firepower of Leviathan's secondary artillery.
