Sam observed the spirit stone powder in his hands while injecting the high amounts of spiritual energy.

After a few seconds, he felt the powder grains started forming bonds again and an irregular solid structure formed in his hand.

Sam was completely astonished as he stopped his spiritual energy and looked at the solid structure.

The structure is completely irregular and it isn't even like a crystal when it was in its initial used up spirit stone form.

While he was observing the structure, suddenly it collapsed again and turned back to its powder form. He didn't understand the reason at all and continuously conducted the experiments.

He tried to use the core of the stone along with it and he tried to make the structure better by controlling the powder neatly and he discovered something new.

His control over moulding the spirit stone powder is just like his control over moulding the spiritual energy. He was able to make all kinds of shapes with enough concentration.

With this, he used the core and started building the structure just like a normal spirit stone but he didn't create any energy veins and injected his spiritual energy into the core.

But the result was same as before, it only sustained for a few seconds and collapsed.

Sam finally felt that he has an inkling to get this working, that is not because he got new ideas but rather, he found that there is something that he missed and that is making the energy channels.

He sat down and completely focused his attention and started making the structure again, but this time he didn't make exactly like a spirit stone and he did the whole process he continuously injected the spiritual energy to keep on solidifying it as fast as possible.

Because, the energy veins might collapse if he delays it. Sam started the process and kept going on. After the construction is complete, he injected the spiritual energy.

This time the structure did sustain for some more time, but it still collapsed in the end.

Sam stayed in the tower for more than twenty days inside the tower and outside two days has passed.

He conducted the experiments on and off to know how to make something out of it and he wasn't able to make much progress.

Outside, Watt is still in the process of improving himself to pass the second phase of training. These two days, he stayed in the woods continuously training and his cultivation is also improving due to this. He is on verge of making a breakthrough to the level 2 Acolyte.

But the ability to control his attack properly is still far away. He wanted to ask Sam for some tips but the latter didn't even come out of his room for the past two days. So, he is thinking of
