Luo Chen had considered everything thoroughly.
Moreover, in his Sea of Qi, he had amassed a massive amount of Heaven and Earth Qi full of impurities, which he urgently needed a cultivation technique to refine.
The "Evergreen Sutra" from the Foundation Establishment Chapter was too inefficient.
Only a Third Order Technique could quickly absorb and rapidly transform it into a higher level of Qi Power than Spirit Power.
Therefore, once he had made up his mind, Luo Chen immediately began to practice the "Wood Burning True Technique."
...
It must be said that with Luo Chen's talent for techniques, he was quite effective in studying cultivation techniques.
Additionally, with years of study, he had become very familiar with this technique.
In just four or five days, he had successfully mastered the "Wood Burning True Technique."
In this way, because he had ingested a massive amount of Spirit Qi into his Sea of Qi during Core Formation, it also began to be continuously refined.
