Xiang Fan's life had settled into a highly regimented, almost self-torturing, routine. During the day, he toiled through the most basic tasks in the Qixing Company's repair shop, his hands greasy and sweaty, his wages barely enough to make ends meet. At night, he retreated to his small room, cluttered with spare parts and data terminals, immersed in the virtual transformation lab of the Spirit Realm battlefield, completing the final upgrades for his companions' mechas.

"Hold on a little longer... just one more unit left." Xiang Fan rubbed his reddened eyes, forcing himself to focus on the holographic screen. His fingertips pounded the keyboard, lines of code flowing like water, precisely adjusting the mecha's core adaptation parameters.

This week's efforts had paid off. The Shadow Killer's combat mech, the Black Tortoise Guard's defensive mech, and the Wandering Feather Sword Armor and Sky Sword Armor's dual-sword mechs had all reached the peak of the Golden Core stage. But now, before him lay the final and most challenging mech—the Gu Master mech.

Bai Zang's combat style was distinct from others. He relied not on brute force but on Gu-like insects to influence the course of battle. Poison Gu, tracking Gu, control Gu, virus Gu, mechanical Gu... His mecha was more like a mobile tactical laboratory, and the release of each Gu had the potential to upend the course of battle. However, the problem lay in the Gu Master's extremely complex system. In the past, Bai Zang's mecha would often experience brief pauses due to computational overload. In those fractions of a second, he would be annihilated by a single cannon.

Xiang Fan took a deep breath and tapped his fingers, calling up the Gu Master mecha's database. Hundreds of data streams danced across the screen like dragons. His eyes quickly scanned the screen, rapidly analyzing the existing problems.

"The core computing speed is too slow, and the data encapsulation layer is unstable. Once the enemy hacks into the database, the Gu worm system will crash..." He muttered in a low voice, his hands moving non-stop. Soon, a brand new Gu database architecture was generated on the light screen.

He rewrote the six-layer encapsulation defense, each layer with its own independent psychic isolation mechanism to ensure data security. Even if the enemy attempted to intrude, they would be intercepted layer by layer, unable to affect the Gu worm system at all.

"This way, Bai Zang won't have to worry about operating system lags or system crashes." Xiang Fan nodded with satisfaction. "With just one line of command, he can release tens of thousands of poisonous insects in an instant, turning the entire battlefield into his private domain."

He slumped back in his chair, stretched, and a smug smile crossed his face. The previous Gu Master mecha had almost zero defense, and being locked onto meant death. But now, after the transformation, the Gu Master mecha not only had a significant increase in defense, but also tripled its core computing power, and even optimized the efficiency of Gu worm release.

But a powerful Gu database alone is not enough, Xiang Fan also opened the power core system of the mecha.

"The psychic energy consumption is too high and the mobility is too low..." He frowned, quickly adjusted a set of data, and loaded a new psychic energy circulation module into the virtual model of the Gu Master mecha.

After this transformation, the engine efficiency of the mecha has increased threefold. Not only can it move at high speed, but it can also continuously release large-scale poisonous insect attacks with minimal spiritual energy consumption.

"Alright." Xiang Fan breathed a sigh of relief, looking at the brand new Gu Master mecha on the screen, and tapped the screen lightly, "Bai Zang, you won't be killed instantly this time."

He had already imagined the next team battle, when Bai Zang would control the mecha and release poisonous insects wantonly on the battlefield, tormenting the enemy to tears. Thinking of this, he couldn't help but smile mischievously.

"Hey, this is interesting."

Xiang Fan yawned, rubbed his dry eyes, and finally typed the last line of code. As the command input was completed, the data flow on the light screen suddenly stabilized, and a clear prompt popped up on the system interface:

[Gu Master Mecha: Transformation Completed!]

【Final test is about to begin...】

He breathed a long sigh of relief, leaned back in his chair, and stretched his stiff neck, his joints cracking. A week of intense transformation finally came to an end at this moment.

"Done...!" Xiang Fan raised his lips with a smug smile and clicked on the 'Test Battle' option. The holographic screen instantly changed and entered combat mode.

Experimental mode, battle test

[Test Opponent: 10 Jindan Peak-level AI Mechas]

Xiang Fan glanced at the system settings and chose "Start Battle" without hesitation.

"Come on, let me see your true strength." He pointed his finger at the light screen, and the battle officially began.

The battlefield loaded instantly, and ten AI mechas quickly surrounded them like hunting beasts. However, the Gu Master mecha at this moment was no longer the "fragile auxiliary" that could only hide in the back and cast Gu, but a completely evolved tactical monster.

With the support of the new psychic engine, the Gu Master mecha's mobility has made a qualitative leap. The moment it starts, it retreats like lightning, like a streak of black light. As it retreats, the rune array on the back of the mecha lights up, and countless black and gold light spots are sprinkled onto the battlefield like stardust.

[Release Tracking Gu x1000]

The AI ​​mechas had just locked onto their targets and were about to launch an attack when they were overwhelmed by a swarm of rapidly wriggling poisonous insects the next second. The system immediately issued an alarm.

[The target mecha is infected with a virus! The system is paralyzed!]

Xiang Fan raised the corner of his mouth slightly, his eyes filled with a hint of amusement: "This is just the beginning."

Runes appeared once again around the Gu Master's mecha, and a series of even more terrifying spells were quickly activated.

[Release Poison Gu × 500, Stealing Gu × 300, Explosive Gu × 100, Parasitic Gu × 50]

In an instant, the battlefield was completely covered by thousands of poisonous insects. The dense swarm of insects was like a black wave, devouring the AI ​​mecha at an astonishing speed. The poisonous insects drilled into the energy core, the explosive insects accurately attached themselves to the joints, and the parasitic insects directly penetrated the enemy's psychic circuits, madly biting the system permissions.

Ten Jindan-level AI mechas didn't even have time to react effectively before they were paralyzed and collapsed in a series of explosions, eventually turning into scrap metal all over the ground.

The entire battlefield turned into a terrifying hell of poisonous insects.

[The battle is over! Winner: Gu Master Mecha!]

Xiang Fan's eyes swept across the data interface, confirming that the performance of the mecha was stable. He nodded with satisfaction, his eyes gleaming with excitement.

"This time, Bai Zang will finally not be the one in the team who gets taken down by a single shot." He grinned and patted the virtual model of the Gu Master mecha on the screen. "When I hand the mecha over to him tomorrow, I think he'll be so happy that he won't be able to sleep."

He stretched and rubbed his sore shoulders. Although he was so sleepy that he could hardly open his eyes, he felt extremely satisfied.

Everyone's mecha has been upgraded, and the next battle will be the moment of their true transformation.
