Gu Jinlai had previously estimated that to elevate the Eternal Furnace from Mahayana to Perfection, two to three hundred Qingguangs would be needed.
Over the years, when he had excess Qingguang, he occasionally used it for minor upgrades to the Eternal Furnace.
The most notable change was that after entering the "Eternal Immortal" Super Boost State and then restoring stability, the time reduced from three months to two and a half months.

His understanding of this Golden Technique was also continuously climbing.

Overall power enhancement.
Body refinement efficiency enhancement.
Transmission characteristic enhancement.
Stability enhancement.
...
In every aspect, a comprehensive strengthening was undertaken.
