Money was only secondarily for buying Beast Crystals to increase his strength.
Most importantly, he needed to save up to buy a "Source Dao Meridian" to break through the Silver Rank barrier. A single one cost as much as one hundred million.
It was only after coming here that he learned there were two ways for Spirit Martial Practitioners to advance to Silver Rank.
The first was to advance solely by absorbing Beast Crystals, though that would waste a great deal of time.
The second was to absorb a Source Dao Meridian and advance in one go.
Other than saving time, there seemed to be no difference.
But things existed for a reason. Not only could a Source Dao Meridian allow a Spirit Martial Practitioner to advance perfectly without side effects, it could also grant its user an additional meridian.
That was fitting for the term "Spirit Meridian."
Do not underestimate that extra Spirit Meridian. It allowed the user's total spiritual power and future cultivation speed to far surpass those of Spirit Martial Practitioners who advanced to Silver Rank through Beast Crystals. As the saying went, one step ahead meant staying ahead at every step.
Most importantly, when absorbing a Source Dao Meridian, there was a small chance it would produce a corresponding martial skill based on the user's innate talent.
That was also why so many people remained stuck at Bronze Rank and could not advance to Silver Rank. They simply could not afford a Source Dao Meridian and had no choice but to advance by absorbing Beast Crystals.
Leaving Lin Pangpang aside, Su Wuming himself could not smoothly advance with just one Source Dao Meridian. That was related to his physique.
He could tell from the fact that his usual cultivation required nearly twice as many Beast Crystals
