"I did it,"
"Speak, speak, speak, right now!!"
Yagen, "The use of Twilight comes with consequences. This weapon wasn't found by my Construction Book, and in the end, I really miss you."
The last statement is nonsense, but the first two are obviously more important.
'The use of Twilight comes with consequences.'
"What consequences?"
"Every time you use Twilight, you pay with your humanity as the price," Yagen said, "it could be memories or certain personality traits, like the desire to protect your people, or your care for someone."
In other words, using Twilight could greatly alter Bailuo's disposition, or even turn him into someone else.
"That dangerous?"
Bailuo hadn't realized Twilight came with such terrifying side effects.
No wonder he felt like he was being influenced by some force ever since he acquired Twilight, "Is this what Twilight wants?"
