Zhou Chun hadn't deployed his Fourth Order Puppet for a very long time.
Initially, when he was pursued by the Blood Robe middle-aged man, he nearly exhausted all the Spiritual Power within the three Spirit Crystals that powered the Fourth Order Puppet, thereby temporarily rendering this trump card ineffective.
Over these three years, he had placed two of the Spirit Crystals in his cave dwelling to slowly absorb Spiritual Energy and restore themselves, while he traded the other one with Wei Yong for a fully charged Spirit Crystal.
On this offensive against Yinxuan Cave, Wei Yong also exchanged another Spirit Crystal with Zhou Chun before departure.
Therefore, he now had two fully charged Spirit Crystals in his possession.
Two fully charged Spirit Crystals were enough to sustain a Fourth Order lower-tier Puppet at full force for the duration of two quarter-hours.
