For the upgrade of his most core card [Historical Explorer (UR)], Leonard Ethan naturally hoped it would be faster, so he prepared as soon as he got the upgrade card.
Because Joan was now accompanying him, the process was much simpler. He just needed to briefly tell Joan what he was about to do next.
If others were in her place, they might ask various questions or even become curious. But for a historical figure like Joan, she knew exactly what had happened and took corresponding action.
"Don't worry, I will follow your commands." Joan nodded solemnly. "I'll make sure that no outsiders disturb you at that crucial moment tomorrow."
Fortunately, Leonard's current identity was a historian, so it was normal for him to lock himself in a chamber for days, and no one would suspect anything.
More importantly, all the interview-related work had been completed, so no one would disturb him recently. Leonard had already informed the people at the plantation not to bother him the next day.
