Looking back at the Wei army fighting away from home, once time was prolonged, food and ammunition would become problems. Not to mention that when enemy reinforcements arrived, Wei might face attacks from the north, reversing the situation.

From Xiao Yan’s standpoint, Feng Miaojun thought that the Wei forces could only secure total victory by swiftly breaching Inzi City.

This indirectly explained how difficult it was for Wei to attack Yao. The entire strategy relied on clever tactics, and although Xiao Yan and Yun Ya’s plans had been implemented smoothly, even so, this final challenge would still stump even the greatest of heroes.

With victory in sight, what methods would the Wei forces use to avoid failure at the last moment?

The next morning, just past the time of the rooster’s crow, Xiao Yan provided the answer.

Inzi City’s defensive formation was no secret. All the great generals of various kingdoms knew that this ancient city was arranged with the ancient formation “Celestial Balance.” Other formations only had a single formation eye, which, once broken, would cause the formation to collapse by itself. However, this formation’s eyes were uncapped at the top. It could be formed by connecting large and small formations, linked together as a whole through complex arrangements to achieve the principle of “balanced power.”

The peculiarity of this formation lay in its ability to redistribute the entire formation’s power at any time. Whenever any sub-formation suffered a fierce attack and was about to be breached, the Celestial Balance formation could divert power from other formations to replenish it.

In other words, these sub-formations were all connected as a whole, sharing both losses and benefits. No matter which part of the formation the enemy attacked, they were essentially confronting the entire Celestial Balance formation.

This was certainly not an easy task.

Of course, high efficiency comes with high consumption. To maintain the operation of the Celestial Balance formation and prevent it from breaking under Wei’s fierce attacks, the spirit stones used up within two hours could pile into a small mountain.

It was fortunate that the Yao Kingdom had abundant financial resources and astonishing reserves. If it were New Xia, how could they afford such losses?

On this point, Feng Miaojun was quite envious.

Looking at the Wei army, not to mention other consumption, just the shells fired in these two days were countless. Xiao Yan had truly bet it all, and the spirit stones spent were probably no less than those of Inzi City.

But this intensity of attack still couldn’t break the Celestial Balance formation, unless both sides were competing on attrition.

Although the Wei Kingdom was prosperous, Feng Miaojun didn’t favor Xiao Yan, after all, the Wei people were fighting away from home. How could their spirit stone reserves be as abundant as Inzi City’s?

But that morning, the sky-shaking cannon fire suddenly stopped.

During these dozen or so hours, the Yao people had become numb to the cannon fire and accustomed to the pungent smell of gunpowder. When the cannon fire abruptly ceased, everyone looked at each other, all harboring immense hope:

Had the Wei forces run out of artillery? If they still couldn’t capture Inzi City by now, would they retreat in the face of difficulty?

But this tranquility was filled with an oppressive sense of an impending storm, making people’s hearts feel heavy, unable to catch their breath.

All was silent.

Then, Feng Miaojun heard a thunderous boom, as if heaven and earth were splitting apart.

Compared to it, all previous cannon fires seemed as insignificant as firecrackers. She had already circulated her energy in preparation, so she wasn’t mentally disturbed, though the porcelain cup before her cracked with a “crack” sound.

But ordinary people couldn’t withstand this; who knows how many were directly knocked unconscious, blood flowing from their ears.

The entire city shook as if struck by a whip, trembling so much that people couldn’t stand steady.

Most importantly, the pale golden light of the Celestial Balance formation also rippled like agitated water, as if someone had thrown a large stone into a calm pond.

Wasn’t it supposed to be the most solid and strongest? A layer of gloom rose in the hearts of Yao cultivators. Feng Miaojun was greatly startled. She flew to the rooftop to look around and saw black smoke rising from the western part of Inzi City, covering half the clear sky and obscuring the formation’s light.

What kind of artillery could have such power?

Immediately after, a second bright spot appeared in the sky, as dazzling as the rising sun. Feng Miaojun’s heart skipped a beat when she saw it: the second shot was coming, how could it be so quick?

Just as the thought arose, it hit the formation squarely, with a radiant light so bright that even Feng Miaojun immediately closed her eyes, not daring to face it directly.

Still from the west.

With the second thunderous boom, invisible shock waves spread in all directions. The ground outside the formation couldn’t withstand the second devastation and instantly became barren. Although Inzi City was protected by the formation and wasn’t destroyed, many civilian houses split into pieces during the tremors.

Then came the third shot.

Though each bombardment was incredibly powerful, the intervals were tens of breaths apart, giving the Celestial Balance formation a little time for self-adjustment, otherwise, it would have broken long ago.

And they all came from one direction. Feng Miaojun narrowed her eyes toward the west.

What did that indicate?

These super cannons, with power far beyond ordinary imagination, had a single shot equivalent to a hundred regular spirit artillery shells. Most terrifying was the concentrated force striking a single point, so the explosive effect couldn’t be calculated by simple addition. But the frequency of bombardment was so low, probably because, for such weapons, the Wei army only had one or two.

This was highly possible. Such treasures weren’t of the present world; perhaps the Wei people had obtained them from some ancient relic? Xiao Yan had truly been patient, only bringing it out now.

In Feng Miaojun’s memory, there was indeed a divine item whose power matched this. The ancient texts in Yanhai Tower recorded an overwhelmingly powerful weapon called the Giant Spirit Cannon, which could break through a fortress with just one shot, a killing weapon used by the ancient demon army against alien races. But even in ancient times, it was a rare treasure. The crafting technique was highly secretive, with no branches across the continent, and its value was astonishingly expensive.

Of course, with each fired shell, the spirit stones consumed could directly drain the reserves of a small country today.

Moreover, the Giant Spirit Cannon’s power was too much even for itself to bear; each could only fire six shells before being scrapped.

The cost, the shells, the depreciation—each was shockingly expensive, but you get what you pay for, and the effect was equally shockingly good. The Celestial Balance formation was praised as an almost flawless formation. Many powerful beings, including Feng Miaojun, had originally believed that such stubborn defense could only be broken from within, otherwise it would require a gradual grinding approach.

But now, the Wei people had brought out such a bottom-drawer killer!

After taking three consecutive hits, the Celestial Balance formation’s light had already dimmed considerably.

Feng Miaojun heard the restless sounds spreading around her. Though ordinary people didn’t fully understand the celestial phenomena, they instinctively felt fear.

In just a few dozen breaths, for a large formation, it wasn’t enough time to arrange an effective defense.

So the Giant Spirit Cannon fired its fourth shot.

Feng Miaojun closed her eyes at the right moment and thought: “It’s over.”

Indeed, when two treasures from ancient times clashed, they again produced an earth-shattering boom. Then the Celestial Balance formation suddenly burst with a strong light, like a final flash, vanishing like a soap bubble. This was an overall weakening; even with more than ten formations connected as one, they couldn’t withstand the power of the Giant Spirit Cannon.

Without obstruction, the Giant Spirit Cannon’s shell penetrated through seven or eight small formations like a hot knife through butter, finally landing and blooming!
