Invincible Super System Modifier

They stared blankly at the scene before them. How powerful was the monster that kept repeating itself, but how long had it been?    

In less than three minutes, the monster was killed?    

What kind of speed was this?    

Also, what kind of strength was this?    

"This monster, isn't it strong?" Brother Snake asked stiffly.    

"I don't know." Lin Fei said, "Because it didn't almost attack, I don't know if it's strong or not. Anyway, it's an instant kill."    

"Instant kill!"    

Snake Brother said excitedly, "Can I be as strong as you?"    

"I think so." Lin Fei thought for a while and said, "If I can be so strong, so can you."    

"Thank you."    

With Lin Fei's encouragement, Snake Brother was so excited that his body trembled.    

After making the last cut, Lin Fei turned around and returned to the power center. The girl was still there, and the energy core had not been taken away.    

When he returned to the power center, Lin Fei saw the huge Titan Generator again.    

This generator was even longer than a train, and it was dozens of meters tall. It was incomparably huge, and the monster just now was like a gecko, hanging on the generator and absorbing power.    

"I found the energy core." At this moment, the girl ran over with a smile on her face.    

There was a box in her hand. It was not very big. She opened the box for Lin Fei to see. There were four crystals the size of half a fist inside.    

"These are the energy cores." The girl said, "One piece is enough for a small Titan Generator to operate for a few months."    

Lin Fei put the box into his backpack and smiled, "When we find a place to live, we can try this thing and see if it's useful or not."    

"Of course it's useful." The young girl said matter-of-factly, "The Titan Generator is one of the greatest inventions."    

"I trust you." Lin Fei smiled and said, "But now, we should go to the gathering."    

The young girl nodded and said, "You still need to take the test again."    

Lin Fei carried the young girl and left. According to the direction pointed by the previous few people, they soon saw the gathering. As usual, after passing the inspection at the entrance, the young girl pulled Lin Fei and went straight to the guild.    

"May I ask what I can do for you?" After the service staff found out that Lin Fei was an E class, their attitude was still very good.    

Lin Fei smiled and said, "I want to take the upgrade assessment."    

"Then please show me your card. I will contact the testing staff right away."    

Finally, the staff brought Lin Fei to an empty area. This was the outskirts of the gathering, but there were still many people here.    

Most of the people here were taking the test.    

The young girl followed him here and looked at Lin Fei's figure with anticipation.    

"The test you are applying for is a D-class test." The staff member said, because there was a rule stating that the level had to be increased by one level.    

One was not allowed to directly advance from E class to S class!    

"D class test?"    

The staff member's voice immediately attracted the attention of the surrounding people. Numerous curious eyes looked over and landed on Lin Fei.    

"E class?"    

"I didn't expect there to really be an E Class in this world. I wonder what kind of strength is needed to be able to make a difference to E Class, hahaha."    

"He's already E class, yet he still dares to participate in the upgrade exam."    

They were all here to watch the show.    

Because their strength was not bad, the weakest among them was at D class. When they saw Lin Fei and found out that he was at E class, all of them revealed a look of disdain.    

Their level was higher, so they felt proud in their hearts.    

A mere E class.
