After Merlin had trained using the relief sculpture for a few days, he could feel some obvious changes. Even if it was not comparable to the Spell Models built by the Spell Caster civilization, it could reach a terrifying point.
However, the only thing to worry about was whether these relief sculpture postures would work or not.
Therefore, after noticing that there was no one in the room, Merlin began to practice the relief sculpture postures in his memory. Merlin had not practiced these postures for a long time. In the Void Zone, this was Aruba's set of cultivation techniques, which was a failure. However, if he could practice it to the peak, it would also be very powerful. At least, there would be no problems in protecting himself in this world.
