After Kallen finished off one purple armored soldier, she turned her gaze toward the other two armored soldiers. With a "bang," two hook cables shot out from the armor on her chest. The hook cables hit one purple armored soldier, wrapping around this armored soldier's right arm and shoulder. The hook cables rapidly retracted, quickly closing the distance between Kallen and this armored soldier.

"This is bad." That armored soldier sensed something was wrong and hurriedly swung his short sword, slashing at Kallen's body.

Kallen leaped up, avoiding the short sword's attack. Her feet kicked at the armored soldier's chest, kicking him to the ground. Kallen's left hand pressed down on this armored soldier's right wrist, preventing him from using his short sword, while her right steel claw gripped tightly onto this armored soldier's left chest position.

"Please, spare me." A panicked voice came from this purple armored soldier's face armor. Having just seen his companion die at Kallen's hands, this armored soldier knew he was no match for Kallen and could only beg for mercy in a mournful voice.

"Say that to the comrades of mine you killed!" Kallen remained unmoved. The palm area of her right steel claw emitted a dazzling red light, and a red sphere bursting with electric light appeared. The red sphere slowly penetrated into the purple armored soldier's heart area.

That purple armored soldier let out a desperate scream, his body shaking violently. After about ten seconds, he stopped struggling and lay motionless on the ground.

"This is bad..." The last purple armored soldier, seeing his companions killed one after another, knew he was no match for Kallen. He could only abandon his companions and speed toward the distance, fleeing in panic. Seeing that this armored soldier had already escaped quite far, Kallen gave up the pursuit and returned to Captain Guan's side.

"Well done, Kallen! You really helped me vent my anger. That was so satisfying, haha! Ow, that hurts..." A-Bing shouted joyfully. He wanted to raise both hands to celebrate, but because it pulled at his left arm's wound, he grimaced in pain.

"Phew, that was suffocating." Kallen complained. She grabbed her helmet with both hands, removed it, and shook her hair while breathing in the fresh air in large gulps. Behind the helmet appeared the face of a young girl with wheat-colored skin. This girl had clear, bright, determined eyes and red hair that reached her neck.

Captain Guan said: "Kallen, these two are Rulu and Nana. They're Mayor Qiao's family members. As for Mayor Qiao, whom we were supposed to rescue... unfortunately, we weren't able to save him. He and his wife have already met with misfortune."

"I see..." Kallen's face darkened, feeling sad about the fate of Mayor Qiao and his wife. She turned her face and carefully looked over Rulu and Nana. Probably because she found Rulu quite handsome, Kallen was clearly stunned when she saw him. Her gaze stayed on Rulu's face for several seconds without moving away.

With a "whoosh," Rulu leaped from the vehicle and came to Kallen's side. His face carried a polite smile as he looked at Kallen and said: "Hello, I'm Rulu. Thank you for saving Nana and me just now."

"Ah, it's nothing, just a small matter." Kallen said in a nonchalant tone, then she added in a somber voice: "I'm very sorry about Mayor Qiao. At the time, I had to collect intelligence nearby to ensure the safety of the surrounding environment, so..."

"It's not your fault. Anyway, thank you very much." Rulu gazed at Kallen's face and said solemnly. Under Rulu's intense gaze at close range, Kallen couldn't help but blush on her face. Feeling somewhat shy, she turned her face away and shifted her gaze.

The scene paused for several seconds. Suddenly Kallen thought of something and said somewhat strangely: "Huh? It's more than four meters from here to the vehicle. How could you jump so far in one go?"

Rulu smiled slightly and said: "There's nothing strange about that, right? You should be able to do something like this too."

"Of course I can. A distance like this is nothing for me." Kallen said with full confidence, but then she realized something was off and called out: "Wait, that's not right. I'm me and you're you. How can we be compared? Tell me quickly, how did you jump so far in one go?"

Seeing Kallen so serious, Rulu couldn't help but start joking: "It's very simple. First, put your feet together, crouch down and push hard downward, then use the wind to push down, keep your hands flat to maintain balance, and that's it."

Kallen was stunned for a moment. She realized that Rulu was teasing her and said with some displeasure: "You guy, do you take me for a fool? Actually, even if you don't say it, I know. You're an Ultra-capable, right?"

"Yes, that's right. I'm a level four Magic Ultra-capable." Rulu showed good judgment and didn't continue joking, answering Kallen seriously.

"Oh, a level four Magic Ultra-capable. That's really impressive. By the way, you..." Kallen couldn't help but feel respect for Rulu. She wanted to say something more, but at this moment, Rulu turned around and walked toward the vehicle, saying:

"Alright, we need to go. Sanctuary's army should come again. The longer we stay here, the more dangerous it becomes for us."

Captain Guan also said: "That's right. Whatever we need to talk about can wait until we leave the Concession area."

Kallen nodded, put her helmet back on, and the two armored vehicles and the red armored soldier all moved along the road together. During the next few minutes, nothing happened, and the group was about to arrive at their target destination—the underground tunnel entrance.

Up ahead on the road, in an extremely open area, stood a large stone structure like a small mountain. On this structure was a dark, semicircular large opening. Rulu, Captain Guan, and their group were heading toward this dark opening.
