"The engraving method inside this core... seems to be an old but extremely sophisticated psychic energy flow structure?"

He frowned and carefully analyzed the complex rune circuits. The more he looked, the more he felt something was wrong.

"Logically, this engraving method has long been obsolete. Why is this mecha still using it?"

As he pondered, he gently slid his fingers across the engraved surface, and suddenly an idea struck him—

"Wait, if I can improve this design... can I make it even more energy efficient than the new system?"

This idea suddenly made him excited!

If this speculation is true, then this mecha can not only be repaired, but it may also gain an unexpected increase in combat effectiveness!

He took a deep breath, quickly organized his thoughts, and formulated a repair plan—

The first step is to repair the main psychic circuit. This requires precision welding and psychic repair. The repair shop may be able to find the right tools, but I'll have to find a way to "borrow" them for work tomorrow.

The second step is to repair the energy core. This is the most difficult part and cannot be completed with ordinary tools. You need to go to the black market to see if there are any cheap second-hand rune carving knives. Otherwise, you can only find a way to modify existing tools yourself.

The third step was to optimize the psychic circuit design. He already had several optimization ideas. If the experiment was successful, he could even make the mecha's psychic output more stable than a regular Jindan-level mecha.

Looking at the scattered parts on the floor, Xiang Fan rubbed his hands together, full of energy.

"This time, I must make you move!"

He clenched his fists, his eyes burning with a strong fighting spirit.

Outside the window, the night is deep, but the lights of the city in the distance are still bright, reflecting the counterattack of this little repairman, which quietly unfolds...
