"Boom boom."

Brilliant fireworks exploded like thunder not far from the Mingdou Mountain Range, and the continuous dense explosions almost completely obscured their vision.

Enchanted by wind magic, brass cannonballs filled with a large amount of compressed fire emitted a blind, fiery glow one after another.

The deafening sound and strong kinetic energy stirred up layers of ripples in the linkage shield, constantly spreading towards the whole.

But it was clear that these shells did not cause damage to the fortress of the Mingdou Mountains itself.

The soldiers who were closer only felt a wave of heat rushing over their faces.

The hot air blew inward, and while they were screaming, they subconsciously threw away the metal products in their hands and quickly moved away from the observation window.

The Soul Guide Shield can withstand the explosion, but it can't isolate the full temperature.

Only the Invincible Shield, a full-featured type of shield, can resist the temperature.

However, even so, countless soldiers still had uncontrollable smiles on their faces.

This first wave of attacks seems to have been blocked?

The linkage soul guide shield is awesome!

The high-energy compression array soul guide is awesome!

"Didn't break through! The linkage soul guide shield is still strong! ”

"Although the artillery fire of the Immortal Empire is far away, it seems that it is the same thing now!"

"A salvo of thousands of custom-built soul guide shells, tsk tsk, I don't know how many more rounds they can fire?"

"Hurrah, luck."

Countless voices rang out one after another throughout the fortress, and many people couldn't help but start cheering in low voices.

The morale of the entire fortress was suddenly renewed.

Something called self-confidence quickly rose in the hearts of these guys who had been like eggplants before.

These soldiers couldn't help but begin to fantasize: without the charge of the Titled Douluo Knights, maybe the Immortal Empire would not be so terrifying.

Even if the other party has ten Extreme Douluo, relying on the strength of the soul guide, we are also confident that we can hold on!

In the fortress, the uneasy soldiers of the Sun and Moon Empire seemed to be temporarily diluted by the stability of the linkage defense barrier, and their faces finally showed a little happiness.

However, this is only limited to ordinary soldiers and low-level soul masters.

None of those soul masters above level 7 could laugh.

Especially the group of ninth-level soul masters gathered in the highest combat command room, their faces were gloomy and could almost drip water.

It's almost written on the face of four words - my day your mother!

There are even some people who have cursed in low voices.

The scolding is quite dirty.

The spiritual perception ability of the middle and low-level soul masters is not strong enough, and they can't judge the true power of these so-called "fixed soul guide shells" at all.

But these high-level soul masters are different.

The people who can stand here are all top people with strong scientific research ability and combat ability.

More or less have a certain understanding of the custom soul guide cannonball, the iconic weapon of the Sun and Moon Empire.

Judging from the feedback from those shells bombarding on the linkage defense shield, the energy level of these shells is at least no less than that of the sixth-level or so fixed-mounted soul guide shells.

However, they do not have a corresponding hierarchical aura on their bodies.

The soul guide is a very mysterious thing.

Especially after starting from the fourth level, every soul guide, as long as it is a complete finished product, will form a unique aura on it because of the formation core and formation patterns.

Or rather, a unique energy fluctuation.

This is also the only criterion for judging the level of a soul guide, not that it is like a first-to-third-level soul guide, and the level can be determined with a pat on the brain.

And what about these shells that just exploded in front of you?

The sky has the power of a sixth-level fixed soul guide projectile, but there is no corresponding level aura at all.

Nothing is just power.

If only one or two people judge in this way, then it can also be proved that there may be a perceptual error caused by the impact of the explosion.

However, now all the high-level soul masters present are aware.

And the most important thing is that the tons and tons of energy fluctuation detectors above the mountain fortress did not give the corresponding level warning at all!

In the feedback of the energy fluctuation detector, the pile of shells that exploded in front of him was not even the lowest standard of fixed soul guide shells.

Not at the first level!

At most, it's only half a level!

What is the concept of half-level?

Civilian, the most ordinary, two gold soul coins can buy a soul guide lamp, this thing is half level.

It's such a thing, you told me that it can burst out with the power of a sixth-level fixed soul guide projectile?

Are you kidding?

But the facts are in front of them, and they have to believe it.

Data and feedback don't lie.

Low-level means that it can be manufactured in batches at a very low cost.

Some of the ninth-level soul masters had already started to communicate with each other through transmission.

Obviously, the round of test firing just now had already begun to impact the inherent three views of these high-level soul masters.

Now, in addition to their gloomy faces, one by one they have begun to doubt their lives, and even doubt what they have learned all their lives.

Tangerine looked at Kong Deming.

She didn't speak, but those puzzled eyes said it all.

At that time, Tangerine was also an excellent soul master who studied with Xuan Ziwen.

Coupled with the fact that she has been exposed to it over the years, she can naturally detect the strangeness of these shells.

Kong Lao frowned slightly, nodded slightly, and affirmed the idea of oranges.

This is by no means a custom-built soul guide cannonball, absolutely not.

Watching a new round of a thousand cannonballs fall like meteors, re-exploding brilliant flames of light on the linkage soul guide shield, this level 10 soul master thought so.

In fact, this is indeed not a custom-built soul guide shell.

This is an ordinary cannonball, and it basically belongs to the category that can't be hit by eight poles with a fixed soul guide cannonball.

The traditional fixed-mount soul guide shells are basically the way of missiles.

First of all, through the launch device, guide your soul power to charge the internal core circle, form a thrust behind the entire cannonball, and push yourself out.

During the flight, it continues to charge the core circle in the warhead to overflow.

Eventually, an explosion is created by a collision.

This is also the reason why the range of the custom-built soul guide shell is so impressive.

It's quite stupid, so to speak.

Therefore, with the inspiration of the cannonball on the blue star, Wanatou improved the current one.

All the shells that are used by the Divine Punishment Heavy Artillery and have a staggering length of one meter can be called warheads.

There is no regular shell case on the Blue Star cannonball, and there is no need to reload the propellant, and all firing functions are completed by the Divine Punishment Heavy Cannon itself.

Qian Chaoguang has adjusted the focus of his research a long time ago.

How to get ordinary people to use soul guides is not the general direction of research.

How to let a low-level soul master use a high-level soul guide, this is the future of the soul master system.

If you do something like the legend of the Dragon King, convert the soul power into electricity and then use it, isn't this pure taking off your pants and farting?

The soul master himself can already manipulate soul power, so why do you need another energy loss?

The Immortal Empire was unable to create a soul guide that could be used by ordinary people in a short period of time.

But the Immortal Empire can allow ordinary people to directly possess soul power in a short period of time!

In this way, there is no need to consider the problem that ordinary people can't use it.

As long as there is a trace of soul power in the body, you can use your own soul power to guide the soul power in the bottle, which is very simple and rude.

Thus, the Divine Punishment Heavy Artillery and the corresponding cannonballs were born.

The shells used in this kind of divine punishment heavy artillery have nothing new in the shell, and they do not use any expensive and rare metal materials.

This material was simply and crudely named Cannonball Steel.

Ninety-nine percent of the No. 1 cannon steel is made up of steel, and the remaining one percent is mixed with several rare metal scraps.

There is a lot of iron on the Douluo Continent, and that bit of rare metal scrap can be recovered from the low-level core circle carving production line every day.

In the end, all you need to do is apply the lowest level of Solid Enchantment to it in large batches.

It's very simple.

With a magic array machine carving, the last energy injection process can be enchanted by a person casually.

Pure fool operation, without any difficulty.

Such a shell is simply typical of waste utilization, and the cost of construction is outrageously low.

The inside of the cannonball is used to make explosives for kinetic energy, and the cannonball ghost and vegetable head are even more brain-opening.

He used the principle of the Li Mei incendiary bomb back then, and used the magic alchemy technology of the Holy Demon Continent to standardize and compress the fire element in the second level and directly fill it into the cannonball.

Stuffed, sealed.

The tip of the warhead is filled with a simple cured version of the Buddha's Fury Tang Lotus gunpowder formula, which is only a line away from the compressed fire element, just enough to blow up a part of the solid enchantment circuit.

In this way, the working principle of the Divine Punishment Cannon is also clear.

First of all, the soul master directs the energy in the bottle to recharge the Divine Punishment Cannon, lighting up all the acceleration circles and wind magic enchantments.

When the cannonballs are filled, the Soul Master starts firing with a mechanical structure.

At that time, the rear of the charged Divine Punishment Cannon's firing pod will generate thrust through soul blasting.

As the cannonball passes through the barrel, it is accelerated eighteen times by the acceleration circle, and attached to it is a cloud of wind elemental that reduces weight and air resistance.

Regardless of the way the shell collides with the target, the outermost layer of wind will disperse and produce a strong concussion.

This kind of concussion will help the fire elemental break through the thin line of blockade with explosives.

With the failure of the Solid Enchantment, the unrestricted compression of the fire element will release intense heat and tremendous kinetic energy at the same time.

This is much more powerful and flexible than any high-concentration explosive.

There's no cost yet, just build a few elemental collectors, it's very simple.

If you want to be more powerful, you have to compress it to three, four, and five levels - of course, this will increase the solidity of the shell.

Or directly increase the volume of the shells, which is also a solution.

If you want to be less powerful, then reduce the volume of ammunition and reduce the concentration of fire elements, which is easy.

Now this combination is the most cost-effective in combination with the cabbage head.

It is powerful, simple to manufacture, and low cost.

To make such a cannonball, if you don't count the labor and production line wear, the cost is probably only about two Golden Soul Coins.

Such a low price, coupled with the industrial production system that the Immortal Empire has long established.

As a result, this thing has accumulated many, many warehouses over the past few years.

After the successful research of this kind of cannonball, Qian Chaoguang ordered someone to find a sleeping volcano rich in fire elements, and built a production base underground to save his life.

The beast tide hit the back with a lack of soul guide shells, which made his phobia of lack of firepower more and more serious.

Of course, even if the reserves are really insufficient, even the on-site production is in time.

Anyway, the space technology of the Immortal Empire is at its best, and it goes directly into the barrel of the cannon after getting off the production line, without any delay.

Under such circumstances, what awaits the Sun and Moon Empire is an almost endless rain of cannonballs.

Every three minutes, the artillery positions of the Immortal Empire fired a salvo, which was equivalent to pouring 20,000 rounds of Level 6 Soul Guide shells per hour.

What is even more terrifying is that the cattle lasted from the afternoon until 12 o'clock in the middle of the night.

Except for an hour's break to eat at six to seven o'clock in the evening, the rest of the stunned did not stop at all, accurately maintaining a terrifying frequency every three minutes.

From afternoon to evening, they poured more than 100,000 shells towards the Mingdou Mountain Range!

The deafening roar continued.

The Sun and Moon Imperial army in the mountain fortress was already numb.

More than 100,000 rounds of sixth-level soul guide shells!

Where did the Undead Empire come from?

If it weren't for the fact that the linkage defense soul guide barrier had been impregnable, the morale of the Sun and Moon Empire's army would probably fall below the freezing point now.

At twelve o'clock in the morning, the Undead Empire stopped its attack on time.

The undead kept vigil, and a hundred and one magic towers shone with a halo of pale gold, enveloping the entire position.

Under the protection of these reliable comrades-in-arms, the soul masters of the human warband camped on the spot and fell asleep one after another.

The Ming Dou Mountain Range's linkage soul guide barrier was finally closed at two o'clock in the morning, giving these soul guides who had been running at high intensity for several hours a chance to rest.

A large number of soul masters began to overhaul it, checking for any breakage or overload that needed to be replaced.

This is the lifeblood of all people, and there is no room for error.

In the supreme operations command room, Tangerine rubbed his temples vigorously and looked at the adjutant who had just gotten the summary information.

"How much soul power do we have left?"

"Back to the Queen Mother, except for the high-energy sealed milk bottle that has not yet been activated, there are only forty-eight percent of the soul power reserves left in the high-energy compression array soul guide." The adjutant replied immediately.

Hearing this data, Tangerine's heart suddenly sank.

This is not good news.

In a few hours, just by relying on the coverage of a large number of fixed-mounted soul guide shells, the undead empire forcibly destroyed more than half of the total energy reserves.

This is based on the premise that the light energy conversion device is constantly turned on!

A large number of light energy conversion devices are fully powered, and they have been supplying energy to the soul guides of the high-energy compression array non-stop.

And today's daytime is still a rare good weather, and the light energy conversion device can transform more soul power.

But even so, in the afternoon defense, the soul power reserve continued to decline.

The conversion frequency can't keep up with the consumption rate of the other party. (End of chapter)
