[Master, these people probably died a horrible death, so they turned into vengeful souls. Since they have become like this, you don't need to think about saving them, and it's better if you absorb them all at once to increase your soul power.]
Zhang Fei naturally wanted to increase his soul power, but he was curious about why they were trapped there until they transformed into vengeful souls. 'Mei, how much beast essence do I have now? Is there a technique to purify souls in the beast abilities shop?'
[You have two and a half million beast essences, Master. There are three soul-purifying abilities, but you can only buy low-grade ones now, and the price is one million beast essences. You need five million and ten million beast essences to purchase the intermediate and advanced grades of purifying abilities. Although soul light purification is only at a low level, it should be capable of purifying these souls, and it can also be used to remove impurities from other people's souls.]
