Lucas continued to walk, but after remembering that if someone saw him back here, it would cause some ruckus. Thus, he cast a mystical art that could make himself invisible. With the conditions and applications the same as with magic, he was able to smoothly cast the spell.
Him contacting five people that could help the three provinces' defense didn't mean that he was returning here to stay. He still needed to make good use of his time, so he prioritized sending people and introducing them. Therefore, after entering the palace, he contacted Yuna.
'Yuna, this is me... Lucas.'
A thin thread was created that immediately traced where Yuna was. She was in her bedroom, resting on her bed when suddenly the thread reached her, carrying the message Lucas sent.
'Mind Communication?'
[Huh? Brother Lucas? You have returned!]
