Zhang Zian was busy the whole day and now it was almost time for him to go to bed.
Zhang Zian had been exhausted throughout the day, but now that he knew the elves' lives could be extended, his tiredness vanished completely. However, he hadn't told the news to Old Time Tea or the other elves yet. As Pi had said, it wasn't the right time. If he hastily told the news to everyone, they would be too expectful. The reality might be too disappointing. For that reason, they might as well not know about it in the first place.
Even if the lifetime of the elves really could be extended infinitely, the elves had to go through an extremely difficult process to do so. Judging from Pi's stern expression as it read the untitled book, Zhang Zian figured that this may be his biggest challenge and trial since he downloaded the Pet Hunter game.
