The Shadow Killer raised his eyebrows proudly and whispered back, "Boss, you are worthy of being like this. You can handle this situation!"

The Xuanwu guard breathed a sigh of relief and patted him on the shoulder. "Well done, Xiang Fan. With that expression on the Transformer's face, it's rare to find someone who dares to bargain with him like that."

Half an hour later, the engineer handed the debugged C-class array circuit board to the Xuanwu guard, and said with a hint of warning, "Take your things and leave immediately. If you stay here for even one minute longer, you could become a target."

The Shadow Killer's smile faded instantly, and he glanced around warily. Sure enough, a few mechas were hovering nonchalantly not far away. While their pilots made no visible movements, their gazes were fixed on them like hawks.

"Tsk tsk, this place really doesn't make people feel at ease for even a second." Shadow Killer muttered softly.

The Xuanwu guard's eyes darkened, and he whispered, "Those guys must be eyeing our trade. Boss, let's get going."

Xiang Fan nodded and restarted the Zero Mech. His voice was calm and low. "Don't look back. Try not to attract their attention. Take your time and don't show any flaws."

The three men, in tacit coordination, slowly maneuvered their mechas toward the black market's exit. Their movements appeared normal, but the constant stares from those around them made them uneasy. Every step felt like walking on a knife's edge, the tension so intense that even the air seemed to freeze.

When the shadow of the black market was finally left behind and they entered a relatively safe area, Shadow Killer almost breathed a sigh of relief: "My God, this damn place is so oppressive! Can we try not to come here in the future?"

The Xuanwu guard patted the armor plate and whispered, "Stop shouting. Talk when you're safe. The way you looked just now, someone must be regretting not trying to rob you."

Xiang Fan stopped the Zero Mech and gently took out the parts he had just traded. He lowered his head and carefully examined them. After confirming that they were correct, he said calmly, "Let's not talk about this for now. I have the things. I will deal with the transformation of the Red Flame Crystal as soon as I return. You guys wait for the news."

The Xuanwu guard patted his shoulder and smiled naively, "Boss, thank you for your hard work this time. After this wave of modifications, our mecha will definitely be able to reach a higher level!"

Shadow Killer also came over and said with a wink, "Boss, I'm really looking forward to it! Next time, my Shadow Killer must be twice as fast as it is now!"

Xiang Fan glanced at him and waved his hand gently: "Don't worry, I won't let you down." Although the words were plain, there was a hint of confidence in his tone.

The three of them controlled the mecha and slowly drove towards the deeper chaotic area. The light spots in the void flickered in the reflection of the mecha, as if silently cheering for their success.
