บท 603: Unit Price of 80 Spiritual Stones

There was a lot more work involved in crafting an Upper Lv 4 weapon, compared to a Lower Lv 4 weapon. More than 20 materials were required to craft just one weapon.

He put more than a dozen main materials into the furnace and steadily started to melt them. Now that Su Mo had advanced to the True Darkness Realm, the fire created from his Dark Force was even stronger. It wasn't long before everything had melted.

It took less than 15 minutes for all the materials to melt.

The next step was to remove the impurities from the melted materials. Thanks to his strong willpower, he easily sifted them out.

He spent another 15 minutes refining the melted materials to their purest form.

He added three more materials into the furnace.

Two of them were added to increase the weapon's durability, while the third was added to stabilize it.
