According to Ye Lingyun's description, there were thirteen branch halls within One-Leaf Paradise, and each one was extremely powerful.
In One-Leaf Paradise, these thirteen branch halls had a strong level of independence and rarely coordinated with one another, mostly not interfering with each other's affairs.
The reason for the existence of thirteen branch halls was because the Sect Leader of One-Leaf Paradise, or the Paradise Master, cultivated the Buddhist secret techniques.
In Buddhism, thirteen is a very special number, representing the completion of merit.
Generally, Buddhist pagodas have thirteen floors as a standard, because Buddhists believe that thirteen floors represent the teaching grounds of Buddha and the center of the three thousand great worlds.
In the transmission of Buddhism in China, there are also exactly thirteen sects.
Therefore, One-Leaf Paradise had established thirteen branch halls.
