As the heavy soul cannons fired, the five onlookers were still filled with curiosity.
When they saw the powerful beams of soul energy being launched, they were amazed and finally understood.
So, this so-called heavy soul cannon gathers and concentrates soul energy using a device, then blasts it outward.
But as they watched the beams of soul energy continue to split, their expressions began to change.
When they saw the beams of soul energy drawing in the surrounding spiritual energy and growing stronger, their faces turned to shock.
And when they witnessed the countless rays of soul energy bombarding the opposing formation barrier, creating a series of explosions, the earth shaking beneath them, the five of them began to show signs of fear.
They finally understood why Yaonie had earlier wondered aloud if the Blackhorn Clan was out of their minds for not stopping them from constructing the heavy soul cannons.
At first, the five of them had agreed with the Blackhorn Clan's decision. The formation on the mountain city was already unstable, and if they didn't quickly reinforce it, it could easily be breached under a strong attack.
In contrast, why would they need to stop the construction of ten structures below? The urgent priority was clearly to restore the formation.
But now, after witnessing the ten heavy soul cannons firing in unison, they fully realized that the Blackhorn Clan should have attacked them, preventing the construction of those ten heavy soul cannons at all costs.
In fact, this method of combat had been known in Lin Qian's previous life as the "Tower Defense Strategy." During national wars, players would build soul cannons right below the enemy's city walls, engaging in a positional battle with the enemy's wall-mounted soul cannons.
However, the Tower Defense Strategy was not something everyone could afford to use. It had another name—"The Strategy of the Wealthy."
First, it required the rapid construction of structures, and researching the necessary technology for this was extremely costly, beyond the reach of ordinary players.
But executing the Tower Defense Strategy was not easy either. Players had become skilled at countering it, often sending waves of soldiers to disrupt construction, even at the cost of their lives.
But in this otherworldly realm, Lin Qian saw the opposing side as mere "country bumpkins" who had no idea what a soul cannon was, let alone understanding the concept of Tower Defense Strategy. Trying to explain it to them would be a waste of time.
Lin Qian relied on the fact that the Hua Xia Empire's forces, with their superior equipment, formidable strength, and impeccable coordination, were entirely unknown to this world.
The methods and weapons of war used by the Hua Xia Empire were foreign and unfamiliar to the people of this world.
"Those on the other side must have suffered heavy casualties," murmured Xu Wuwei as he gazed at the smoke and dust still rising in the distance. He had not yet recovered from the shock of the earlier explosions.
Lin Qian heard Xu Wuwei's murmur and chuckled, shaking his head, "At most, only the Lifeblood Realm Blackhorn soldiers behind the barrier died in large numbers. The Void Breaking Realm soldiers might have been injured, but there wasn't much impact beyond that."
Lin Qian's words surprised the five onlookers.
They had seen firsthand the devastating power of the heavy soul cannons and couldn't believe that the damage was so minimal.
Seeing their confusion, Lin Qian explained as he looked at the mountain city, "The power and targeting of the heavy soul cannons were carefully designed by the Fireworks Department to evenly distribute the force across the enemy's barrier."
"Moreover, the formation virus that invaded the enemy's formation strengthens the barrier at the moment of impact, thus weakening the force of the heavy soul cannons."
Lin Qian paused before continuing, "If the heavy soul cannons were to fire at full power, they could collapse a significant portion of the mountain city, killing not only the innocent Blackhorn civilians but also the enslaved members of the four races. They would all die for nothing."
"Breaking the formation is sufficient; leave the task of defeating the enemy to Yaonie."
After Lin Qian finished speaking, the five of them felt a complex mix of emotions.
They admired Lin Qian's sense of justice—thinking of not harming the innocent even at a time like this. To have such a ruler, they believed, the people of the Hua Xia Empire must live very well.
At the same time, they felt a sense of awe and respect for the Hua Xia Empire's Fireworks Department.
Even though they didn't fully understand what this Fireworks Department was, the fact that they could precisely control such terrifying soul energy and ensure that no harm came to the inside of the mountain city during the attack was awe-inspiring.
The smoke and dust gradually dispersed, revealing the mountain city that had been struck by the heavy soul cannons.
At this moment, the Blackhorn Clan's mountain city was fully exposed. The once-glowing formation patterns on the mountain wall had been shattered, leaving charred marks all over.
In the openings along the mountain wall, the figures of Blackhorn soldiers could be seen. They stared back at Lin Qian's direction with lingering fear in their eyes, fixated on the ten heavy soul cannons, their expressions filled with terror.
The continuous bombardment of soul energy rays had lasted for thirty full seconds, making them feel as though they had been trapped in a nightmare.
The formation masters who had been repairing the formation and searching for the cause of its instability stared wide-eyed ahead.
They couldn't understand how such a powerful formation could have disappeared in an instant.
In past defensive battles, simply holding the formation, unless the disparity in strength was too great, could have held out for over a month at least, or even six months at most.
But now? The formation was gone in the time it took to drink a cup of tea.
"Huaxia!" At this moment, Yaonie, standing at the forefront, suddenly raised his Cold Moon battle blade and pointed it forward, roaring loudly.
"Kill!"
The ten thousand blood warriors behind Yaonie also raised their battle blades and roared in unison.
The murderous shouts echoed throughout the entire land.
Yaonie's Cold Moon battle blade remained raised as his eyes gradually turned blood-red, his blood boiling within him, his skin turning crimson as steam rose from his body.
"A general leading the army, blood boiling!" Yaonie growled, his blood-red face twisted into a savage grin as he gripped his Cold Moon battle blade tightly.
"Crush them!"
