Chapter 159: Hammering and Refining, the Thousand Refinement Treasure Embryo

Master Lin watched as Lu Qing's heavy hammer struck down.

Under the enormous force, the glowing red iron bar, in an instant, sparked as it was compressed and collapsed, turning into an iron disk.

Then Lu Qing folded it and struck down with another heavy blow, hammering it back into an iron disk once again.

In this manner, Lu Qing swung his hammer, one strike following another.

The iron bar, like dough, was easily flattened by his blows.

But Master Lin and his disciples understood that it wasn't that the iron bar was as soft as dough, but rather that Lu Qing's strength was truly astonishing.

Each swing could easily flatten the iron bar.

What was most crucial, Master Lin and his followers noticed, was that Lu Qing was not just blindly pounding with brute force.

Instead, each hammer strike contained various changes and was just enough to reach the limit of the iron bar, squeezing out the impurities within, yet not so powerful as to break the metal.
