There was silence in the test room, except for the imperceptible "rustle" of the card-making knife moving in the original crystal card.

Luo Xiaofei's movements are getting faster and faster, he has gradually sorted out his thoughts and is confident. Feeling the secret energy flowing smoothly in the new secret pattern, he knew he was on a path to success.

On the other side, the invigilator's old man's face had become very complicated. Sometimes confused, sometimes abrupt, sometimes solemn......

"This kid is not messing around!" He felt an incredible sense of shock in his heart, "The logic of these lines he innovated is very rigorous, and he can't find any fault in theory, is there really room for improvement in the temperature control card?"

"Sizzle...... This knife is wonderful!" Suddenly, when the old man saw the wonderful, his whole body seemed to be overpowered, his hairs stood up, and the pores of his body were opened, and he couldn't say how comfortable it was.

This is a pleasure that can only be understood by a card maker! Just like a programmer sees a beautiful piece of code, a mathematician sees a beautiful formula, and that kind of happiness is something that a scumbag cannot experience in his life.

The old man drank alcohol, his mind was completely attracted by the wonderful lines that appeared from time to time under Luo Xiaofei's knife, and he forgot everything outside his body, even Luo Xiaofei didn't know when to put down the card making knife, he didn't find it.

"There is nothing wrong with the lines added to this section, but whether it will work or not depends on the actual performance after activation!"

Luo Xiaofei sat in front of the workbench, he had already repeatedly tested the secret pattern of this temporary innovation several times, and found nothing wrong. And this whim innovation also gave him a lot of new insights into card-making, and his realm seemed to have been raised to a higher level.

"It seems that even without fusing the rune shading, I have the ability to create new cards, which are a treasure of another world!"

Neither the old nor the young spoke, they were all pondering and feeling, until a crisp bell rang: "Ding Ling Bell Bell ......"

The system prompt also sounded: "It's time to test, please put down all your tools, get out of your seat, and wait for the test to be evaluated." ”

Luo Xiaofei woke up from his contemplation, stood up, and stood next to the workbench.

The bell also woke up the old man of the invigilator, he picked up the walkie-talkie and said a few words, then stood up and walked over, looked at Luo Xiaofei with complicated eyes for a while, then patted him on the shoulder, walked to the workbench, verified the identity of the invigilator, picked up the temperature control card, and began to test and evaluate.

"The secret energy reserve is 1 point, which is very standard. He looked at the data, nodded and said that the newly added lines did not affect the energy storage system, which was already a preliminary success.

"The overall smooth operation of the secret energy, with no blockages and additional losses, shows that the lines you added blended well with the original secret pattern. The old man's voice became more and more excited, and finally, he put down the detection instrument and said excitedly: "Next, as long as this card can be successfully activated and operated, you will be completely successful, child!"

"Hmm!" Luo Xiaofei was also looking forward to it.

"Bang bang bang!" a staff member knocked on the door, brought a brand new secret energy air conditioner, and then withdrew without saying a word.

The old man of the invigilator first connected the testing instrument to the air conditioner, then inserted the temperature control card into the card slot of the air conditioner, and then inserted a charging card into another card slot, rubbed his hands, and said: "Child, it's time to see what the frequency conversion function you are talking about!"

After speaking, he gently pressed the button next to the charging card slot, and the energy indicator light on the secret energy air conditioner lit up and started normally.

The old man pressed the temperature button a few more times to set the temperature to 20 degrees, and suddenly, the indicator light representing cooling also lit up, and a cool breeze blew out from the air conditioning outlet.

This is the real silence!

Luo Xiaofei couldn't help but sigh with emotion, the air conditioner driven by cards did not make any other sound except for the slight sound of the wind, and this alone could completely explode the air conditioner on the earth.

Soon, the temperature in the test room dropped to the preset 20 degrees, the air conditioner quietly inverted, and the cold air suddenly became much gentler. The old man of the invigilator, who had been watching the testing instrument, immediately saw the same, and a look of surprise suddenly appeared on his face.

"There was no downtime, the secret energy output was reduced by 42%, which is enough power to maintain the current temperature, and the fluctuations should not exceed 0.5 degrees!" he said.

"It's successful!" Luo Xiaofei felt a stone in his heart completely landed, clenched his fist and waved it a few times.

"You've really succeeded!" The old man of the invigilator stared at him, and sighed with emotion: "You have really improved the secret pattern map that has been used for 200 years, which is amazing! It is also a very useful improvement, and the preliminary estimate is that the frequency conversion function you add should be able to save 30% of the secret energy, which is amazing!"

"Then did I pass the test?" Luo Xiaofei asked.

"Of course!" The old man of the invigilator returned to the display screen and wrote the eye-catching assessment results on Luo Xiaofei's registration application form - perfect!

Subsequently, he signed his name: Liu Liancheng.

This name is in a signature font, Luo Xiaofei looked at it for a long time, but he didn't recognize which three words it was. Of course, it doesn't matter, as long as the invigilator signs, it doesn't matter what his name is, anyway, there will be no intersection in the future!

After passing the test, Luo Xiaofei only needs to go to the hall and wait to receive the emblem and membership card, of course, his information has been uploaded on the Internet, and now he is a real card master.

"Thank you!" Luo Xiaofei bowed to the old man of the invigilator, this old man was not wearing a badge, and he couldn't tell what level of card master he was, but he must be very powerful.

"Don't thank me, I also suspended your card production this time, fortunately it didn't affect the test, otherwise I made a big mistake!" Liu Liancheng shook his head and said to himself.

Luo Xiaofei didn't say anything, so he prepared to leave.

"Wait!" Liu Liancheng stopped him again and said, "Kid, you have improved the secret pattern of the temperature control card, and if you want, you can apply for a patent for the inverter system." ”

"Apply for a patent?" Luo Xiaofei's eyes lit up, and with the patent in hand, it means that he may sell a huge sum of money at any time.

"Do you want to pay the money?" he asked quickly.

"Of course, but it's not expensive, and if you register a patent in all countries in the big league, it will only cost about 30,000 yuan......," Liu said.

"Thirty thousand?" Luo Xiaofei suddenly stopped, his heart was like water, and said: "Thank you, but I still won't register the patent for the time being...... By the way, no one will preemptively sign up, right?"

"Who dare?" Liu Liancheng glared and said, "The test process just now was recorded throughout the whole process, and now it has been transmitted to the database of the headquarters of the Card Masters Association, and even the president can only consult it, and cannot do anything else with the video, if anyone dares to preemptively register, you can sue him for bankruptcy!"

"That's good!" Luo Xiaofei was relieved.
