After three hundred years of accumulation, today's Song Zhong can be described as a strong soldier. The half-immortal thunder produced in the Wutu Divine Palace has refined more than one hundred and twenty Wutu half-immortal thunder flying boats. The number of Otogi Divine Thunder also increased greatly, and it gradually exceeded the output of the Wutu Divine Thunder, and finally made the number of Otogi Divine Boats even more, reaching 150.

Most of these flying boats are 1,200 zhang long, and only 10 of them reach 1,500 zhang. The reason for this is not that the divine thunder in Song Zhong's hands is not enough, but that he does not have so many genuine artifacts as the core, that is, these ten genuine artifacts that are needed, and Song Zhong worked hard to get them. For this reason, he even contributed his own earth-opening divine shuttle.

Without a genuine artifact as the core, the larger the flying boat, the more high-grade spirit stones will be consumed, and although Song Zhong is rich, he can't supply hundreds of large flying boats.

Therefore, those secondary flying boats, Song Zhong also installed pseudo-immortal weapons as cores, although they are not as powerful as the immortal core, but they are enough to support the operation of 1200 zhang flying boats.

After having so many Divine Thunder Flying Boats, Song Zhong's confidence also became sufficient. However, he still hasn't revealed these big killer weapons in front of others. Most of the flying boats were hidden, and only about ten were left outside for people to see.

Even those ten, after adding the powerful Thunder Divine Boat and the Chilling Ice Divine Boat, have become an extremely powerful force. It's enough to fight against any super sect.

If Song Zhong's hidden army came out together, he would be able to sweep through half of the cultivation realm. And such a powerful armed force has not yet satisfied Song Zhong, and he is still keeping the flower demons below to step up manufacturing, and continue to increase the inventory with the number of one per year.

Even if the follow-up flying boat doesn't have an immortal core, it doesn't matter. Song Zhong intends to use them as a backup. When you have an immortal weapon, you can upgrade it to a top-level flying boat that can fight.

In addition, they are extremely useful in the event of a major war. In the unlikely event that the flying ship on the front line is damaged and needs to be overhauled, the core can be replaced so that it can be quickly put into battle.

Of course, in the past three hundred years, Song Zhong has not completely copied the design of the Thunder Dao people. He himself also made necessary changes to the Divine Thunder Flying Boat according to the actual combat situation.

The main changes are two. One is a way to supplement the core aura, and the other is the Divine Thunder Tower.

It turned out that when Song Zhong was commanding ten Divine Thunder Flying Boats at the same time and conducting combat exercises, he suddenly discovered an extremely serious problem, a big problem that would turn his Flying Boat fleet into garbage if it was not done well. It was in response to this problem that he was forced to transform and upgrade Shenzhou.

And this problem is the power problem of the Divine Thunder Flying Boat. You must know that all the top flying boats in the cultivation realm are based on genuine immortal weapons, so that when they are fighting, they can use the special abilities of immortal weapons to continuously absorb the aura of the surrounding heaven and earth, and quickly replenish and consume.

Because the speed at which the immortal weapon absorbs the vitality is super fast, it is even greater than the usual consumption of the top-level flying boat, so it makes this top-level flying boat a war fortress that will never fall, and can even confront the scattered immortals.

However, in the cultivation realm, top-level flying boats are extremely rare, and there are only one or two of them in each super sect, so that even if it is a sect war, there will not be many top-level flying boats gathered.

Even in the spiritual realm where the aura is poor, the huge realm is filled with a sufficient amount of aura to supply the consumption of several top-level flying ships. So in general, this is not a problem at all.

However, Song Zhong did not have just three or five top-level flying boats in his hands, but there were more than a dozen of them, and there were also nearly 300 second-level divine boats that could also absorb the aura of heaven and earth for combat. With such a large number of fleets, if they desperately absorb the aura of heaven and earth together during a big war, it will be a very terrifying demand. Even the lower spirit realms cannot guarantee supplies. Even the spiritual realm, which is rich in spiritual energy, cannot support such a large amount of consumption for a long time.

And once a large number of heaven and earth aura in the spirit world disappears, not only Song Zhong's fleet will become useless waste, but it will also have a catastrophic consequence for the entire spirit world, and maybe all the living beings in it will be killed. Let it be a complete wasteland.

Song Zhong is not a murderer, and of course he can't allow such a thing to happen. And he may also fight in special realms, such as the Nine Hells and the Endless Abyss, where the aura of heaven and earth itself is very meager, but the evil qi and demonic qi are extremely abundant. If you still want to rely on absorbing the aura of heaven and earth to fight, then you will inevitably suffer a big loss.

So as soon as this problem appeared, it immediately attracted Song Zhong's attention. After nearly 100 years of research, Song Zhong finally managed to solve this problem through two improvements.

One of Song Zhong's solutions was to change the way the Divine Thunder Flying Boat replenished its aura. In addition to exposing their ability to absorb the aura of heaven and earth on their own, it also allows them to absorb the stored divine thunder as power.

After all, these flying boats are all made of divine thunder, and they do not reject the divine thunder of the same origin and root at all, and with a slight change, they can transform the thunder ball of the same surname into their own aura. It's the same as using spirit stones to supplement aura, but the spirit stones with thin aura are replaced with thunderballs with huge aura.

In this way, as long as Song Zhong reserves enough divine thunder in the Divine Thunder Flying Boat in advance, he can use the thunder ball to replenish the spiritual energy when he can't absorb the spiritual energy of heaven and earth, so that the Divine Thunder Flying Boat can continue to fight.

Anyway, for Song Zhong, there are so many subordinate condensed thunderballs, there is no shortage of this thing at all, plus there is enough storage space in the Divine Thunder Flying Boat, there is no problem in storing the mountains, let alone a mere thunderball!

As a result, Song Zhong, who had a lot of money, asked each Divine Thunder Flying Boat to store enough thunderball reserves for the Flying Boat itself to use in continuous combat for a month. With these thunderball reserves, even in a space without the aura of heaven and earth, Song Zhong could make his Divine Thunder Flying Boat fleet exert its tremendous combat effectiveness.

In addition to this improvement, Song Zhong also deliberately improved the Divine Thunder Launcher. In the past, the Divine Thunder Tower was installed on the flying ship as the main weapon. The Divine Thunder Tower can absorb enough aura from the flying boat, condense it into a thunderball, and then automatically aim and launch it. If you want to say convenient, it is really convenient, you can attack automatically without people looking at it.

However, the consumption of the Divine Thunder Tower is too terrifying, this consumption is mainly reflected in two aspects, one is that the Divine Thunder Tower itself is expensive, accounting for almost one-third of the total cost of the flying boat, or even more, and the other is that the Divine Thunder Tower consumes too much aura.

Because the divine thunder launched by the Divine Thunder Tower is made on the spot, then in the process of absorbing the spiritual energy and condensing the thunder ball, it is inevitable to waste a lot of spiritual energy. And the amount of waste of aura is related to the god thunder tower itself, the high-level god thunder tower wastes less aura, and the time of condensation is fast, and the low level is the opposite.

However, even the highest-grade Divine Thunder Pagoda has to waste half of its spiritual energy in the process of condensing the Divine Thunder, and its cost is almost comparable to that of a high-grade spiritual treasure.

In this regard, Song Zhong said that he was under a lot of pressure and always wanted to improve, but he didn't know where to start, until one day, he accidentally discovered a treasure he had obtained when he was young, which inspired him and found a solution.

When he was a congenital monk, he was chased and killed by four foundation building monks, and one of them used this dragon head bombardment cannon to bombard Song Zhong with the earth fire god thunder. If it weren't for the big bronze bells, a hundred Song bells would have died. That was the closest Song Zhong came to death, and he himself was a little scared when he thought about it now.

And after this dragon-headed bombardment cannon was captured by Song Zhong, it was kept by him as a trophy. It wasn't until that day that on a whim, turning over what he had before, that he found it out again.

After seeing this dragon's head bombarding the sky, Song Zhong's eyes suddenly lit up. The Dragon's Head Bombardment Cannon itself can already be regarded as a low-level thing for Song Zhong, but it has given Song Zhong a new revelation.

Because the principle of this dragon's head bombardment cannon is completely different from the principle of releasing divine thunder in the cultivation realm, the divine thunder tower of the cultivation realm is to condense the divine thunder by itself and then throw it out. However, the Dragon's Head Bombardment Cannon was made in advance after the divine thunder was made, and then it was fired when it was used.

Don't look at this little difference, when it comes to using it, it is a world of difference. The Shenlei Tower, which condenses the Divine Thunder, consumes the aura of the Shenzhou itself, and the aura of the Shenzhou itself still needs to fly and defend, which is not much, and it is even more stretched when it is consumed by the Divine Thunder Tower.

The top-level flying boat has almost infinite aura, and it doesn't care, but after Song Zhong formed the Shenzhou fleet, it is impossible to have endless aura, so this consumption is huge.

And if the Shenlei Tower is replaced by a dragon-headed cannon, it will be completely different. The Dragon's Head Bombardment Cannon only consumes a little bit of its own aura, which can be used to aim and fire. The Divine Thunder it needs can be accumulated in normal times, and this time it saves a lot of Divine Thunder Flying Boat's spiritual energy, allowing it to engage in more protracted battles!

Song Zhong quickly figured this out, and then began to collect refining methods for treasures like the Dragon's Head Bombardment Cannon.

With Song Zhong's financial resources and power, of course, collecting these things is no longer a problem, and then coupled with the ingenuity of Shui Jing and others, after spending decades of time, the brand-new treasure 'Divine Thunder Dragon Pattern Cannon' was born.

The Divine Thunder Dragon Pattern Cannon ranges in length from three zhang to thirty zhang according to the need, and it is carved with exquisite dragon patterns, which is extremely gorgeous.

So far, Song Zhong has only built two varieties of Divine Thunder Dragon Pattern Cannons refined by Wutu Semi-Immortal Thunder and Divine Thunder Dragon Pattern Cannons refined by Yimu Divine Thunder, and installed them on the two major types of Divine Thunder Flying Boats under his command.

After the installation of this Divine Thunder Dragon Pattern Cannon, Song Zhong's Divine Thunder Flying Boat suddenly increased its combat power, more than doubling it. It has too many benefits, countless times superior to the god Reta.

In addition to being able to save aura, the Divine Thunder Dragon Pattern Cannon is also cheap after all. Because it doesn't need to condense the divine thunder, and the materials and formations required to condense the divine thunder are the most expensive. If you calculate it, a Divine Thunder Tower can make more than a dozen Divine Thunder Dragon Pattern Cannons of the same level. It was precisely because of this that Song Zhong was able to mobilize more financial resources for collecting pseudo-immortal weapons. Otherwise, he would not have been able to assemble such a large fleet.

In addition, in terms of combat effectiveness, the two things are completely incompatible. The Divine Thunder Tower can only fire one kind of divine thunder, but the Divine Thunder Dragon Pattern Cannon is different, if you install the Wutu Divine Thunder, it will launch the Wutu Divine Thunder, and if you install the Otogi Divine Thunder, it will launch the Otogi Divine Thunder. Moreover, the Divine Thunder Dragon Pattern Cannon made by Otogi Divine Thunder also has a powerful blessing when firing Otogi Divine Thunder.

Although there is no increase in power of the divine thunder of the other lineage, when dealing with enemies of the same surname, it has stronger lethality than the blessed divine thunder of the original system.

In addition to this, the rate of fire is also a huge gap. Because the Shenlei Tower needs to condense the divine thunder, and this process is very time-consuming, generally speaking, the interval between the divine thunder is relatively long, and it takes a few breaths at the shortest.

But the Divine Thunder Dragon Pattern Cannon is different, as long as the cannonballs are sufficient, it can be fired continuously, and with one breath, it can shoot two or three cannons. That is to say, when the Divine Thunder Tower hits one cannon, the Divine Thunder Dragon Pattern Cannon will hit seven or eight cannons, or even a dozen cannons, which is equivalent to increasing the combat effectiveness by several times, and it is naturally much stronger than the Divine Thunder Tower.

Of course, although the Divine Thunder Dragon Pattern Cannon is better than the Divine Thunder Tower, it is not without any shortcomings. Its biggest shortcoming is that it needs to be controlled by a special person, and each Divine Thunder Dragon Pattern Cannon needs a special gunner to load the cannonball, aim and fire. But Shenlei Tower does not need to be so troublesome, fully automatic, extremely labor-saving.

However, this shortcoming is nothing to Song Zhong at all, he has people. Whether it is the flower demon or the puppet man of the Wutu Divine Palace, under the ignition and manufacturing of Song Zhong, each of them exceeds a million in number. Arrange for some people to control the flying boat, and that is not a problem at all.

Besides, after these people go up, it's not just as simple as firing guns. At critical moments, they were also able to personally participate in the battle, which is a combat force that should not be underestimated.

All in all, after being transformed by Song Zhong, the combat effectiveness of the Divine Thunder Flying Boat has increased dramatically, and once a battle breaks out, it will definitely be able to shock the world. It's just that Song Zhong doesn't want to expose his strength for the time being, so as not to become the target of public criticism. It's a pity that Song Zhong's wish was once again disappointed. Sometimes, when you don't make trouble for others, others will come for you!
