Qin Feng had not told Dance of the Moon or Weichen that he could already deal with the Fifth World Spine alone...
After all, no one knew what changes the Deep Blue Civilization's Fifth World Spine would undergo, or what special buffs it would receive.
This was the final hurdle standing in the way of the Deep Blue Civilization's ascension.
Even Qin Feng could not be certain everything would go smoothly when the time came.
So he would have Dance of the Moon and the others prepare first. That way, even if something unexpected happened, they could react instead of becoming lambs to the slaughter.
For example, they could find shadows cast by Moon Fragments to hide in.
If Qin Feng was even a little slow in dealing with it and people had not found shadows to hide in, the casualties could be enormous in an instant, with tens of millions dying at a time.
Right now, the Deep Blue Civilization was also steadily providing Qin Feng with tens of millions of years of lifespan every day.
If fewer people could die, then of course that was better.
At that moment, Qin Feng stared intently at his experience bar...
The seventh class advancement for Shadow had finally arrived!

His experience bar was full, and Qin Feng immediately selected "Yes"!
