Su Xiao sheathed Dragon Slayer Flash. Dragon Slayer Flash had been upgraded to the Immortal grade with a maximum initial rating, which did not surprise Su Xiao. He had expended a huge amount of resources to upgrade it.
Now that Dragon Slayer Flash had reached the Immortal grade, it was time to forge it. The forging process consisted of three aspects: strengthening it with refined Immortal Stones, replacing its gems, and using an Immortal Soul on Dragon Slayer Flash.
The first was strengthening Dragon Slayer Flash's level. This had the lowest threshold but the highest cost.
If strengthening it to +5 was enough, the cost was actually not high. But if one had ambitions and wanted to strengthen Dragon Slayer Flash to +12, it became a bottomless pit.
Next came replacing the gems—replacing the three Holy Spirit-grade gems with Immortal-grade ones. This required not only resources but also a certain amount of luck, so there was no need to rush for now. The three Holy Spirit-grade gems currently installed were also very suitable for Dragon Slayer Flash.
The final aspect was the Immortal Soul, which required careful consideration. Only Immortal-grade weapons could be enhanced through an Immortal Soul, thereby strengthening the weapon's "Core."
Dragon Slayer Flash had two core bonuses: Demonic Blade and Soul Blade. If Demonic Blade were strengthened and its execution threshold increased, it would be an incredible development. At present, it could execute enemies whose health was below 25%.

The effect of Soul Blade was somewhat similar to the Blue Steel Shadow ability. Blue Steel Shadow burned the bodily energy
