At this thought, Chen Nianzhi's expression grew increasingly grave.
To forge such a supreme immortal-grade sword, the first step was to temper the immortal gold and divine iron. The second was to fuse the immortal iron into one's natal immortal sword. The final step was to inscribe immortal-grade law runes; only then could the immortal sword be truly completed.
Of these three steps, refining the divine iron was merely time-consuming and laborious. Given enough time, it could still be refined bit by bit.
The second step tested a cultivator's artifact-refining skill. If the timing for fusing the immortal iron was even slightly mishandled, the finished immortal sword would be uneven in quality, greatly diminishing its power.
Now that Chen Nianzhi had completed the first step and was about to begin the second, he naturally proceeded with utmost caution.
Fortunately, after thousands of years of artifact refinement, his skill in this field ranked among the very best in the Purple Yin Realm. He had some confidence in this fusion.
He saw his chance and, without holding back, fused the Deep Abyss Divine Iron into the Heavenly River Ren-Water Sword. In the span of mere moments, he completed this step in one smooth stroke.
"Success!"

Generally speaking, there were only two ways to accomplish this. The first was for an immortal to acquire immortal materials and forcibly pour their own law power into them, allowing it to merge with the laws within the immortal iron.
The second was to use superb artifact-refining methods to awaken the laws inside the immortal
