Why didn't you said it earlier?

The three of them moved into a room which seems to be made of some unknow metal, but there seems to be heavy pressure coming from this metal.

Meenakshi took out card which seems to be made of wood and started to circulate into it and after a few seconds different types of a particular designs started to appear on the plain walls. These designs continued to appear for six more time a total of seven times.

What Meenakshi just done is opening an array which will consume the world energy which is enough for bone forging realm cultivator to rise a minor realm just by opening a single layer, but she opened such array up to seven levels, the highest in each type of arrays. By a standard calculation one cultivates from 1st patala stage to 9th patala stage.

Even if Meenakshi spent that much of energy, both the elder and Prathika didn't utter any single word, as they also felt that it need to be of such a secure level for them to discuss about something of that standard.
