Jiang Che had worked out quite a few of the mechanics behind the Time Fragment instances.
As far as rewards went, everything awarded for a rating probably already existed within that historical echo, apart from [primordial origin first spirit].
That was true of Willow Source Old Dream, and the same went for Little Hidden Temple.
No... perhaps [primordial origin first spirit] existed there too.
Perhaps the very substance that formed those echoes of time and space was this "essence" he had never heard of anywhere else?
That was nothing more than idle speculation on Jiang Che's part.
Returning to the matter at hand, obtaining [primordial origin first spirit] this time was a good thing. He would not have to farm Willow Source Old Dream specifically for it.
In practice, however, farming Little Hidden Temple was less efficient than farming Willow Source Old Dream.
For the same rating, the rewards from the Little Hidden Temple instance were indeed far greater than those from Willow Source Old Dream. The problem was that Jiang Che had previously been able to consistently achieve a grade Jia rating in Willow Source Old Dream, earning nine wisps of [primordial origin first spirit] per run.
In the Little Hidden Temple instance, even after giving it everything he had, he could only achieve a grade Bing rating, earning a mere five wisps. And opening the new instance once cost three times as much transmigration energy as the old one.
Judging by the rewards alone, it was a terrible deal.
But he could not calculate it purely that way. Apart from hard currency like [primordial origin first spirit], the two instances offered different rewards. In Little Hidden Temple, he could also receive additional instruction from Chunji. That counted as a gain too.
As for Willow Source Old Dream, it
