"Yeah, we can't even optimize, so where's the fix?"

Zhou Cheng's expression became even uglier: "Not you?"

The people in Group D3 all shook their heads with sincere expressions, and they didn't seem to be lying.

There was an eerie silence in the laboratory.

"Then who did it?" Zhou Cheng gritted his teeth and frowned even more tightly.

At the same time, in the repair workshop next door, Xiang Fan was squatting on the ground, concentrating on disassembling the joint parts of an old mecha, and he had no idea that the "casual modification" he made three days ago had caused a storm in the laboratory.

Engineer Hong stood aside, smoking a pipe, observing Xiang Fan's operation and praising him: "Boy, you're really quick at it. The joint design of this mecha is so old, yet you can fix it so smoothly."

Xiang Fan wiped his sweat and grinned: "Hong Gong is still the best teacher."

Engineer Hong nodded and suddenly asked casually, "I heard that the psychic engine in the lab next door was successfully tested. The results were ridiculously good, exceeding the design standards. Tsk tsk, those engineers must have found a treasure this time."

Xiang Fan paused abruptly, his heart tensing, but on the surface he tried to pretend nothing had happened and asked, "Uh...really? Aren't they...fixing the circuit all the time?"

Engineer Hong shrugged. "Who knows? Anyway, this matter has nothing to do with us low-level people. Let's just focus on repairing our mecha."

Xiang Fan quickly lowered his head and pretended to tighten the screws carefully, but his heart was already boiling with anger.

——Could it be... the drawing that I secretly modified three days ago?

He swallowed guiltily and tried to comfort himself: "That shouldn't be the case, right? How could they possibly notice such a small change?"

However, he couldn't help but think back to that night -

He took the opportunity when the document fell to the ground and quietly changed the circuit optimization plan on the drawing, even marking it clearly, for fear that the other party would not understand it.

——As a result, the other party not only understood it, but also actually modified it according to his ideas?

"It's over. If this gets discovered, I will be considered to have modified the experimental documents without permission." Xiang Fan's mind flashed with the scene of himself being fired from the company, and he couldn't help but shudder.

He prayed silently in his heart: "Please, don't find me..."

On the other side, Zhou Cheng had returned to the office, placed the drawing of the "mysterious revised plan" on the table, and fell into deep thought.

He read it over and over again, and the more he read it, the more he felt that the ingenuity of this revision idea was far beyond the level of ordinary engineers in the company.

"Who did it?"

He pulled out his communicator and dialed the number of the head of the R&D department. "That engine sample has passed the test, and its performance has been greatly improved. It fully meets the standards for mass production. Next, let's arrange production."

"Did it really pass?" An incredulous voice came from the other end of the phone.

"Yes, it even far exceeds the design standards." Zhou Cheng paused and added, "However... the author of the revised plan has not been found yet."

"Can't find it?" The person in charge was stunned for a moment, then smiled and said, "Who cares who it is? As long as he can solve the problem, that's fine."

Zhou Cheng hung up the phone, took a deep look at the blueprint, and finally sighed helplessly: "Forget it, the matter is finally resolved anyway."

But his intuition told him that the person who made this change was definitely not a simple person.
