"Sorry, I'll bother you!"

Su Zijing seemed to be too devoted and had no reaction at all. Liu Fei had to step closer to increase the volume.

"Ah...what are you doing?"

Su Su woke up suddenly. When she turned around, she saw that Liu Fei was almost stuck behind her. She couldn't help but jumped up from the chair and looked around subconsciously. She found that the huge laboratory was only left with her and the cleaner in front of her. A hint of panic suddenly appeared on her face.

"I'm not doing anything, I just remind you that the get out of class is over!" Liu Fei took a step back and kept his distance from this woman. The woman exuded a strange fragrance, which made him feel a strange feeling.

"What's going on?" Su Zijing breathed a sigh of relief when she saw Liu Fei take a step back.

"You can leave now."

"Is that right...but there is still more than an hour left to finish class." Su Zijing looked at the time displayed on Guangming and frowned.

"They are all gone." Liu Fei said expressionlessly.

"Do you want me to leave?" Su Zijing suddenly smiled softly.

"Yes." Liu Fei nodded.

"Cough cough..." Su Zijing didn't expect Liu Fei's answer to be so direct, so she quickly coughed to hide her loss of composure.

"But, I still haven't completed the test, sorry." Su Zijing calmed down for a moment, her smile disappeared, and replaced it with Leng Ao, and sat on the chair again.

"..." Liu Fei opened his mouth and couldn't speak.

"It'll be fine soon."

Seeing Liu Fei's face dullness, Su Zijing actually felt a little inexplicable pleasure. Of course, Su Zijing didn't understand the reason. You must know that Su Zijing has been surrounded and flattered by the stars for a long time. Few boys would treat her as coldly as Liu Fei. Seeing Liu Fei being defeated, they would naturally feel pleasure. This is a very common thing in psychology.

Soon, Su Zijing forgot about Liu Fei's existence and once again devoted herself to the test.

As time passed, Liu Fei stood behind Su Zijing like a stone sculpture without moving.

"Sorry, disturb me..." Twenty minutes have passed, and Su Zijing's work seems to have made no progress at all, and Liu Fei finally couldn't help it. For him, this was a huge waste of time. The soldering iron head said that wasting time is tantamount to killing money. Liu Fei has a strong concept of time. Everything is arranged in an orderly manner and will never waste any time.

"Don't bother me." Su Zijing immediately interrupted Liu Fei's words. She was in a bad mood. This was her 23rd optical path test and she could not find the cause of the optical path failure.

"The resistance of the photoelectric circuit mainly depends on the contact resistance between the dynamic and static contacts of the circuit breaker. The existence of the contact resistance increases the loss of the conductor when powered on, causing the temperature at the contact to increase. The magnitude of its value directly affects the current carrying capacity during normal operation, and to a certain extent affects the cutting ability of the short-circuit current. Therefore, the value of the resistance tester for each phase of the circuit breaker is an important data for the installation, maintenance, and quality acceptance of the circuit breaker..."

"Ah..." Su Zijing looked at Liu Fei blankly with an incredible expression.

“I don’t mind helping you with the test.”

Liu Fei was asking Su Zijing for his opinion. In fact, he had already pulled Su Zijing away with the chair without hesitation, and his hands jumped rapidly on the main control board of the light brain, full of rhythm. The indicator lights on the instrument kept flashing, and the data stream on the holographic screen leaked wildly... Two minutes later, a copy of the test optical path data report was spit out of the machine.

"Okay, you can leave."

"Oh." Su Zijing was still sitting in the chair, immersed in shock. If she hadn't had a written document in her hand, she could not believe what had happened just now. The cleaner had done it in just two minutes after spending an afternoon of unfinished test work.

Subconsciously, Su Zijing pinched his fingers, and after feeling the pain, she confirmed that she was not dreaming.

I am a top student!

Looking at Liu Fei who was busy manipulating cleaning equipment, Su Zijing felt frustrated and her self-esteem was seriously damaged for no reason.

"You can leave now!"

Just when Su Zijing was still feeling frustrated, Liu Fei had already completed this cleaning work.

"oh……"

Su Zijing left in absent-minded manner. Strictly speaking, she was driven out by Liu Fei. When Su Zijing walked out of the laboratory door, Liu Fei almost immediately closed the steel gate of the laboratory and headed straight to the mecha laboratory next door, leaving Su Zijing standing in the cold metal corridor in a daze... What Su Zijing thought had nothing to do with Liu Fei. Liu Fei was concerned about the mecha in the mecha laboratory. In his eyes, Su Zijing, the first beauty in Zhuoer Mecha University, did not have a composite armor plate yet, which was attractive.

Like the Optobrain Laboratory, the larger mecha laboratory has become empty, leaving Li Meng busy driving some loading and unloading equipment.

"Ahh! Brother Fei came just right..."

"You do it yourself, I'm going to do something."

"Oh." Although Li Meng was dissatisfied, he had no choice but to do anything. After all, he had plenty of time to squander now.

Liu Fei went straight to a mecha with a full body of Wang Lan. This mecha was transported a few days ago. Liu Fei had no time to study it, and he finally found an opportunity today.

The mecha is eleven meters tall, which is a little shorter than the standard mecha model of humans twelve meters. From the exposed muzzle of the mecha, you can tell that this is not a civilian mecha, but a long-range combat mecha. However, this mecha looks very delicate and lacks the hideousness and heaviness of the Zoer Galaxy combat mecha. Overall, it makes people feel light and fluttering.

Obviously, this is not a mainstream mecha in the Zoer Galaxy.

Although the scientific and technological civilizations of the seven major galaxies all originated from the parent planet Earth, after experiencing the era of interstellar migration and the current interstellar warlord separatism, they each fought on their own, and the mechanical civilization also ushered in an unprecedentedly active situation where a hundred flowers bloomed and a hundred schools of thought contend.

As one of the most popular human-shaped weapons, the mecha is naturally colorful. Due to the different environments and aesthetics of each galaxy, the mecha also has a distinct regional color.

Among the seven galaxies, the Zoer Galaxy is close to the alien star and the fighting mecha has the most powerful style. Compared with the mechas of the six galaxies, the Zoer Galaxy's mechas are much larger in weight and size.

Liu Fei's understanding of mechas is limited to the understanding of mechas of the Zoer galaxy, because it is difficult for Liu Fei to access mechas of other galaxies at his economic level, and the laboratories of Zoer Mechas rarely appear in mechas of other galaxies, which has led to the singularity of Liu Fei's understanding of mechas.

This blue mecha that looks a bit elegant and lively is covered with scars. There is a scrubbing wound on the right robot arm, which cuts off the lower part of the robot arm, revealing the complex light path inside. There is also a shocking wound on the cockpit. From that wound, you can almost see the main control board in the cockpit... undoubtedly, this is a mecha that has been fought fiercely.
