The Heaven and Earth Scale still contained over two hundred jin of General Spirit Level Demon Spirit Malice and over a dozen jin of Slaughter Spirit Level Demon Spirit Malice.
Based on Song Ciwan's current capacity, the upper limit of Lifespan she could trade for in a single transaction was one thousand years. Any more than that, and she might "drift away" again.
Therefore, she could trade at most ten jin of General Spirit Level Demon Spirit Malice or one jin of Slaughter Spirit Level Demon Spirit Malice at a time.
Making ten trades a day, it would only take a little over three days to completely trade away all the Malice.
A little over three days—let's round it up to four.
Thus, Song Ciwan's Lifespan increased by ten thousand years each day. By the end of the third day, her total Lifespan had reached 159,600 years.
By the fourth day, when all the Demon Spirit Malice had been traded, her Lifespan had become 167,300 years.
