Lu Yin immediately summoned Mu Zhu and the others. Since the time had been stripped away, they could use Seek Ancient Source to search for it.
Mu Zhu was all right, but Senior Brother Qing Ping and Senior Brother Mu Xie were struggling. They had helped Lu Yin use Seek Ancient Source against Mr. Wei, and still hadn't recovered.
But this matter was of the utmost importance. If Ku Zu really had a stretch of time stripped away, something very important must have happened during it.
When Ku Zu had charged into the Eternal Clan alone, he hadn't expected to return alive. He had wanted to pave the way for those who came after him, leaving behind some clues in the Eternal Clan even if it cost him his life. When he used the Sequence Rule to escape, he hadn't thought he could truly get away. So before that, he must have tried to leave clues somehow. But Lu Yin had searched the Black Mother Tree and the lands of the Forbidden Zone without finding any.
That stretch of time had been removed, and it had to be connected to Master Cao. But if Master Cao had been in the Forbidden Zone then, why hadn't he killed Ku Zu? If he didn't care, why had he sent Butterfly Tian En to hunt Ku Zu down?
Master Cao had his own reasons. Lu Yin and Ku Zu simply wanted to find out what had happened during that missing stretch of time.
Senior Brother Qing Ping and Senior Brother Mu Xie went to the Five Spirit Clan to recover in Parallel Space-Times where time flowed at a different rate.
They returned only after more than a month. They had spent a long time with the Five Spirit Clan.
