"Pfft, Nebula Level?!" Lynisha was amused by Su Yu: "You're really humorous."
"I'm serious," Su Yu said solemnly.
"Serious? Hahahaha!" Lynisha burst into laughter, clutching her belly, unable to straighten up, and all her gloom from the past few days vanished.
Su Yu did not continue to explain, simply watching her calmly.
Lynisha laughed and laughed, and her laughter gradually subsided.
Because she remembered one thing—Su Yu's energy conversion efficiency seemed terrifyingly high!
Currently, only about ten percent of the four-dimensional space-time energy within her had been guided out.
But just that ten percent of energy was enough to raise Su Yu from First-tier Stellar Level to Third-tier Stellar Level.
If Su Yu absorbed all the four-dimensional space-time energy, to what extent could he improve? Seventh or Eighth Rank Stellar Level?
