The Invisible Spot

"Three Seals," I said ecstatically as I got out of the wooden block; I had created three seals of supreme combat exercise, and I did that within twenty-five minutes before the energy in water is finished.

I could have added more water, but I did not; my veins had reached their limit, and I did not want to overexert them; if I did, I might crush them, and that would be the end of me.

The advancement I got from these sessions was quite good; not only I created the three seals of Supreme Combat Exercise, but I also refined my body and soul through my mana veins.

If I continue doing that, it won't be long before I got a strong body. A body that is even stronger than that of Mary's. 

Mary had an amazingly strong body; if not, she would have burst out like a balloon. I was lucky enough to see how her defensive method burst out like a balloon, and enormous physical energy entered her body.
