The biggest reason why Emperor Shi Tian had to invest a lot of resources to develop the Big White Whale when the war was at its most tense is actually the war in the semi-metal plane.

Because the gravity of the semi-metal plane is too strong, almost all air forces have been destroyed.

Although Emperor Shi Tian’s dog-headed aluminum bat and Yuanmagnetic double-headed dragon can barely participate in the battle, their combat effectiveness has actually been cut to a very low level, even less than 30% of its heyday.

Especially the dog-headed aluminum bat, after losing the ability of carpet bombing, their combat power alone cannot play a big role, so the biggest use now is the Dangdang scout.

Of course, the same is true for the demons. Their small number of air forces are basically destroyed and they don’t even dare to take them out.

So in this sense, the abnormal gravity of the semi-metal plane is fair to both sides.

However, the guy Shi Tiandi is definitely not the kind of existence who likes fair competition. His core combat philosophy, or his persistence in combat theory, is to break the so-called fair combat rules and regulations and specifically use things outside the rules to bully others.

For example, in this battle for the semi-metal plane, since no one can use space, Emperor Shi Tian insists on developing a useful air force and then using the air superiority to bully the other party.

It is precisely because of this that the weirdly designed white whale emerged.

In fact, to be serious, the other big white whales outside are a failed design in the transport ship.

Because the first thing the transport ship considers is transportation costs, and the Big White Whale does not have an advantage in this regard, because he has made too many floating magic arrays. Although the transportation volume has increased, without the acceleration magic array, its speed becomes a flaw.

Too much magic power is consumed in the air, which leads to an increase in transportation costs. After calculation, the transportation cost of the Big White Whale is about 20% higher than the transport ships Shi Tiandi now.

Therefore, the newly emerged silicon-based troops of the Big White Whale cannot be regarded as a qualified transport ship.

However, after reaching the semi-metal plane, the white whale suddenly became the most terrifying existence.

His super floating ability makes him still capable of performing the responsibilities of a transport ship. Although his transportation capacity has been reduced to only one-fifth of the original due to gravity, he still retains the transportation capacity of tens of thousands of tons.

If it is regarded as a transport ship, the Big White Whale may not have a great effect, but if it is treated as a fire support ship, all the space inside is used to carry ammunition, then the situation is completely different.

Tens of thousands of tons of shells are enough to support dozens of various artillery artillery to take a long time.

As a floating transport ship, the big white whale can hover at a height of thousands or even tens of thousands of meters, and then output firepower downwards frantically, making it an extremely terrifying ammunition launching platform.

It is worth mentioning that the super gravity of the semi-metal plane has become a weapon to increase the lethality of the big white whale at this time.

When the heavy bullet fell from a height of tens of thousands of meters, with the support of powerful gravity, the lethality was at least doubled.

Moreover, with the advantage of height, rapid-fire cannons that can usually only fire thousands of times, but now they can attack targets two or three thousand or even four or five thousand meters away.

However, in terms of that distance, the natural lethality can still be guaranteed, but accuracy is not necessary at all, and basically you can only rely on the mystery.

Fortunately, the rapid-fire cannon itself does not require accuracy, with a speed of several thousand bullets per minute, so the targets he aimed at were beaten into dice.

So in this case, the big white whale suddenly became the most terrifying air killer in the semi-metal plane.

When hundreds or even thousands of big white whales appeared over various battle castles, the terrifying torrent of bullets fell from the sky like heavy rain, scattering in every corner of the castle, causing extremely serious damage to the demons attacking on the ground.

In this way, the lethality of each battle fortress instantly increased several times, so that the demon army on the attacking side was caught off guard as soon as it came up. It can basically be said that they had no ability to resist and died as much as they rushed forward.

Without the established legion of Gods participating in the battle, relying solely on a large amount of cannon fodder, I am afraid that I will never break through the terrifying battle fort protected by the Big White Whale.

In desperation, the demon army had to use the unique bloody sacrifice of the abyss again, and use the Forbidden Air Sacrifice to specifically target the white whale.

However, in this process, the loss of the demon army was really too great.

The Abyss Blood Sacrifice is not a joke, at least it must be sacrificed to start tens of thousands of demons.

However, this level of sacrifice can only ban the empty space within a radius of one or two kilometers, and completely affect the big white whale less than ten kilometers away.

If the range of the forbidden air exceeds the range of the Big White Whale, at least one bloody sacrifice of a million level is required.

The most important thing is that a sacrifice of this scale must have a main sacrifice, that is, a legendary demon.

And this is just the beginning. A ban on air can only ensure that the big white whale in one direction will automatically fall, and the attack space it opens is only about ten or twenty kilometers.

Obviously, for the huge battle fortress, even without the help of the Big White Whale, such a small gap can be completely blocked.

So if you want to achieve all-round suppression, the Abyss Blood Sacrifice conducted by the Abyss Demon must have several times, or even more than a dozen times. It depends on the size of the battle fort.

Anyway, for those large war castles, more than a dozen or twenty forbidden air fields can only ensure the safety of attacking the outside of the castle. If you want to attack, you will definitely have to conduct more Abyss Blood Sacrifices.

The most disgusting thing is that the forbidden air domain obtained by the Abyss Blood Sacrifice is not permanent. Although it can last for one or two days, it is considered a relatively long time, for a powerful battle fort, this amount of time is not enough.

Especially for the large war fortress, even if everything goes well, the army of the abyss demons will take at least one or two months or even longer to barely conquer.

If the Abyss Blood Sacrifice is needed on the outer periphery of a large war fort to ensure that the outer periphery is completely banned, this means that in just one or two months of the Abyss Blood Sacrifice, they will have to spend hundreds of legendary demons and hundreds of millions of demon cannon fodder.

This number is really terrifying. If there are so many sacrifices in a large battle fort, then if the entire front is sacrificed, the number of legendary demons and cannon fodder will be a astronomical number.

Anyway, the more than 200 evil gods of the abyss felt a little unbearable. After a few waves of bloody sacrifices, they gave up this method helplessly.

Because they found that these bloody sacrifices did not actually have much effect. Although they did suppress the air firepower white whale, the ground attack still suffered heavy casualties and did not achieve much results.

However, with the end of the forbidden air spell, the fallen white whales took off again, the sacrifices they had made before were basically in vain, and the territory they had occupied was also lost and was seized by others again.

The bullet waterfall falling from the sky is too terrifying to the point where even the powerful army of demons cannot stop the pouring of firepower of such a level.

So in general, after the long-tail four-armed Vajra ape went to the front line in large numbers, even if the attack of the Abyss Demon was curbed, although it could barely advance, the casualties were too great and the speed of the propulsion was too slow, which was a bit unworthy of the loss.

After the big white whales appeared on the battlefield one after another, the abyss demons' attack basically lost their due power and had no way to conquer cities and land. They could only slowly consume each other's troops and supplies, but they could no longer conquer the battle fort.

Anyway, if this continues, even if the demons in the abyss will not be able to drive Emperor Shi Tian out for 100 years.

In a blink of an eye, it has been almost a year since the 200 evil gods attacked Emperor Shi Tian.

During this process, except for losing some peripheral battle forts at the beginning, Emperor Shi Tian basically completely stabilized his front in the later stage, especially after the large number of King Kong Apes and Big White Whale appeared on the battlefield, the front was basically as stable as Mount Tai.

In contrast, although the evil god of the Abyss sacrificed a lot, the effect was very little, and even almost nothing.

Apart from leaving countless corpses under the various front-line battle forts, the demon army did not even destroy the city wall. Compared with their sacrifices, such a battle result was very miserable.

And in the process of the semi-metal plane war, the war outside was in full swing.

Relying on the massive amount of arms sold by Emperor Shi Tian, ​​the troops of the Light Clan have made initial progress on the battlefields of all planes.

One victory after another makes the area controlled by the demon keep shrinking.

Although compared to the huge areas controlled by demons, this level of strength is only equivalent to slow erosion, and it is not a serious matter at all.

However, the successive failures inevitably caused the morale of the demon to suffer a major blow.

Even many demon cannon fodder with low intelligence gradually developed a sense of fear of alchemy weapons.

So often, when a few shells fall down, the huge explosion sounds can scare thousands of demon cannon fodders into a mess, and they will be completely ruined.

And such a thing was never possible in the past.

Even the little evil demons with the lowest combat power had enough courage to attack the golden-level warriors in the past, and even sacrificed themselves.
