The offer of 8 million Gold Coins really tempted Chu You as it was close to the top disciple recruitment price in his past life!
Having taken Dantai Jingning as his disciple, Chu You's disciple slots decreased from 14 to 13. He could still accept 13 more disciples. It wasn't bad having one disciple bring in 8 million Gold Coins, given that the number of disciple slots would likely continue to increase as the guild upgraded later on.
He initially had declined War Soul Ruthless and clearly expressed his real attitude about accepting disciples—because leveling up was quite challenging at this time, everyone was just starting out, and those who could understand this were aware of what a player's high level meant at this stage.
So, rather than presenting an astronomical recruitment price, it was better to directly respond to their stance on accepting disciples—he would be the one choosing disciples, not players picking him as a mentor!
