Inside a dilapidated house in Broken Tooth Fortress, Qiuda was observing Fangtooth City through a peephole. Due to the elevation difference, he could only see a small section of the city gate – the key location they needed to seize immediately after the battle began.

In this ambush operation, the Mojin people would serve as the vanguard for the initial charge.

This wasn't because Brian deliberately used them as expendable pawns, but a chance they had earned for themselves.

Proving oneself through force and exchanging achievements for resources was the prevailing principle in the Far North.

Qiuda came from an insignificant tribe in the oasis. As the Silver Stream Oasis gradually receded, his clan was on the verge of life and death. Otherwise, he wouldn't have taken the enormous risk of dealing with the Northerners. But now, everyone in his clan had safely migrated to Azure Water Port – the evergreen land they had dreamed of. This was the reward he had earned for fighting alongside the Great Chieftain against the Raging Wave and Bone Carver clans.

Therefore, Qiuda's motive for volunteering was simple: killing more enemies would improve his people's lives. As for who the enemies were, that didn't matter. Even devils from hell were not as terrifying as hunger, thirst, and the constant fear of not seeing tomorrow.

He believed that most of the Sand Folk who came here felt the same way.

"Did you find anything?" someone asked from behind.

"No, I can't see anything except that the red mist is getting thicker," Qiuda carefully plugged the hole and turned around.

The questioner was Fala, the smallest member of the team. The qiangzhi on his back was almost as tall as his torso. A deep scar stretched from his forehead to the corner of his mouth, clashing with his youthful features. Qiuda was deeply impressed by this man. Despite his young age, the qualities he displayed in training and combat were extraordinary, even surpassing those of experienced and renowned martial artists.

Logically, such a person couldn't be unknown in the small oasis, but the fact was that Qiuda had never heard of him before.

"We've been waiting for almost two weeks, right?" Fala complained. "Several hundred people crammed into this place, it's enough to drive anyone crazy."

"Didn't Brian say that the devils have giant beasts that can fly? We can only lie in ambush beforehand if we want to avoid attracting the enemy's attention," Qiuda said with a bit of surprise. "Haven't you ever participated in the hunting ritual? It's normal to lie in ambush in the bushes for half a month to hunt a sand worm. What's the problem with waiting a little longer now?"

According to the plan, Iron Axe had mobilized about two thousand people to hide in the northern district of Broken Tooth Fortress, and arranged a reserve force of one thousand people in the inner city further south. The hiding places had been prepared in advance, looking like ruins on the surface, but inside they had built a simple shelter with an upper level for reconnaissance and a lower level for living. Not only were water and food prepared, but even sleeping and waste disposal areas were separated. Although the smell couldn't be completely isolated, it was already a much easier environment compared to the hunting ritual.

He didn't quite understand why the other party would suddenly complain about this.

"You... wouldn't understand." Fala hesitated, then glared at him, and sat down against the wall in annoyance. "What are those iron cans they prepared before for? They dug holes and buried wires, but when the enemy came, there was no movement at all."

"I don't know... but if it's something the Great Chieftain came up with, I wouldn't be surprised by anything."

He had seen too many incredible supplies, tools, and weapons in the past year or so.

"Hopefully, it's not another Berserk Pill," Fala muttered.

Berserk Pill? He seemed to have heard of that somewhere... Just as Qiuda was about to ask, someone poked his head in from below the floorboards. "News from the rear, the attack is about to begin, get ready."

"Phew—" Fala breathed out a sigh of relief. "Finally, we don't have to keep waiting. I'm going down."

Qiuda considered it more carefully, "What's the signal to attack? Is it still the same as planned?"

"That's right," the man replied, "when the bàozhà sound rings out, it's the moment for the entire army to move out."

...

"It's time," Iron Axe put down the telescope and turned to instruct, "Start energizing now."

"Yes!" Two soldiers from the bàopo team vigorously cranked the hand-cranked generator, while the third man placed his hand on the pressure lever.

The long preparation and planning had finally reached the moment of verification. The range of the red mist now covered Wolfheart City, and if the First Army continued to retreat, Broken Tooth Fortress would soon fall into the hands of the devils – these two cities, like Graycastle and Silverlight City, were almost closely connected. In the past, Broken Tooth Fortress, with its treacherous terrain, became an excellent barrier for Fangtooth City. There was even a saying circulating in Wolfheart that "if Broken Tooth is not lost, the King's City is safe". But now, they were going to use Broken Tooth Fortress as a springboard to deliver a head-on blow to the enemies occupying Fangtooth City!

Iron Axe had noticed that the devils didn't always wear those breathing apparatus. Probably, for them, these costumes were also an extra burden. Apart from the Mad Demon Squads that hunted down refugees everywhere, the rest of the enemies basically only operated within the red mist range.

This obviously gave the First Army an opportunity.

"Lord, the bàopo team is ready!"

Iron Axe ordered in a deep voice, "Detonate!"

As the soldier pressed down on the pressure lever, a dazzling red light suddenly rose in the north of Broken Tooth Fortress! More than five hundred iron buckets were detonated simultaneously, and countless golden flames soared into the sky, engulfing the entire King's City—

Everyone heard a continuous roar.

But this was just the beginning.

The buckets contained the rubber worm gel mixed by Kaimo, but more of it was highly flammable fuel and aluminum, magnesium powder and other combustion-supporting agents. When in a solid state, they looked soft and harmless, but when the shock wave of the zhàyào tore them into a mist and sent them into the sky, these dispersed gels became extremely deadly substances. Because the combustion expanded so quickly that it was no different from a bàozhà, the air was heated to nearly a thousand degrees in a very short time, and the expanding airflow further propelled the fire.

A chain reaction occurred at this moment.

Probably exceeding a certain threshold, the fire rain that should have fallen suddenly tore through the sky, and it looked like orange-red lightning, constructing a huge in the city. The spreading flame pattern didn't originate from below, but reversed and spread from the ground to the sky!

Iron Axe was also shocked by this amazing scene. After a moment, he realized that the fire rain had ignited the red mist! This scene seemed step by step, but it actually happened in an instant. The rapidly fenliè red "lightning" instantly filled the entire sky, turning into an airtight罩子!

Then an even bigger bàozhà appeared.

The fiery red罩子 was broken through with a bang, and a huge fireball rose, like a firebird breaking out of its shell, soaring straight into the sky—

This roar far exceeded the sound when the iron bucket was detonated.

Iron Axe even saw the anomaly of the air being distorted around the King's City!

The earth seemed to tremble!
