This acupoint, compared to Zigong, is even larger. "As large as Car Hood" is the origin of its name. It's not difficult for mana to rush into it, but to pass through it, it needs to be first filled with mana.
When it overflows, mana can naturally pass through and reach the Xuanji acupoint.
However, although Shen Luo has perfected the first level of the Nameless Cultivation Technique, the amount of mana stored in his body is very limited, so he can only temporarily stop attempting to break through, and continues to circulate the first level technique to refill his Dantian.
Only after a full four hours did he finally accumulate enough mana to break through Huagai acupoint after another strenuous attempt.
Shen Luo put away his magic spell, wiped the sweat from his forehead, and temporarily stopped his cultivation practice to avoid mental exhaustion. Moderation is the best policy.
