Chapter 55 Sacred Level Heaven

In the Prince's tomb, in the glorious hall, Leon was still working on the breakthrough of the sacred level of the Prince.

As long as the breakthrough was successful, Leon would reach the sacred level—Heaven!

And he would also be the first prince who had successfully advanced his level since the death of the nine princes of Blood Clan!

At this time, the energy fluctuation in the entire hall was extremely terrifying. Even if a marquis-level master appeared in the hall at this time.

Even if he used all his strength to defend himself, he would be killed in an instant, and even would not be able to leave a trace.

"It seems that it's much more difficult than I thought!"

Although a few days had passed, Leon's two acupoints were still as stable.

Leon even didn't see any hope of success.

"System, use all the remaining evolution chances."

In the past few days, Leon had almost used up all the evolution stored in the system.
