17 Grandmasters

"BOOM!"

"The breakthrough," said someone behind me when a large explosion rang out, and a couple of seconds later, the aura of Grandmaster spread into the watching room.

It was just the beginning. 

In the next thirteen minutes, three more explosions rang out, and the Grandmaster class aura spread; in the span of fourteen minutes, all four Inheritance Masters had made a breakthrough into the Grandmaster class.

I cast a glance at the council and grand lord and found of them are surprised with eyes full of amazement and wonder.

All the breakthroughs are not finished; there are five people who still had to breakthroughs, all with bloodlines, and they will take time. 

Unlike the highly modified breakthrough of the Inheritance hosts, the breakthroughs of bloodline hosts are mostly natural with minimum interference from me; they will take time.
