"Is the final level difficult?"

Dale replied, "It's a combined test of the previous levels, and the difficulty has increased significantly. But as long as you're patient and use your previous experience, you can still pass it. This is a reward."

He took out a crystal box, opened it, and saw a crimson crystal inside, which was not the original nucleus.

"Do you know what this is?"

Dale shook his head: "I don't know, you should know, right?"

Chen An had a smile on his face, seemingly understanding everything, but in fact he knew nothing.

He asked Fuyao in his mind.

[This is a star core, containing more energy than an energy crystal]

Chen An was very disappointed. He actually wanted the original nucleus more.

"Master, don't forget that the train's ability to devour protocores is limited. If all of the train's abilities are upgraded to Special Level 4, protocores of the same level will lose their effectiveness. Star cores are always a good thing."

"Just tell me how to use this thing."

As mentioned before, the star core contains abundant energy. This one is equivalent to 10 billion fourth-grade energy crystals. If you carry it with you, you can continuously absorb it without having to spend time specifically absorbing energy crystals. If the train is short of energy, the star core can directly provide energy without any conversion method.

Chen An was surprised: "Hundreds of billions? So this thing is really good."

We can find many fourth-level pronuclei and beyond, but it is hard to say about stellar nuclei.

A genuine smile finally appeared on his face.

"Dale has made a great contribution by passing the final level. I'll reward him with 5 million star coins and 500,000 energy crystals. This will be the same from now on."

When the news was made public, passengers were excited and began to look for the ultimate checkpoint.
