Suddenly

How many layers of schemes was that by now? As cautious as Leonel tried to be, he still almost fell for this old man's trap. After so many centuries, millennia even, of scheming, how could Wise Star Order be so simple? 

First he had tried to gain Leonel's trust by playing the part of amiable elder. When that was seen through, he was prepared to take over Leonel's body in a more forceful way. He then pretended to fall for Leonel's trick when in reality he had read through his junior's thoughts like a book, perfectly countering the ability of the Silver Tablet. 

After that, he ran into a roadblock with Leonel's Scarlet Star Force, but rather than giving up there, he tried to trick Leonel into a pact that really would have given him full control over him. Then, when Leonel saw through that, he already had a secondary trap laid with <Soul Bound> and was waiting for Leonel's soul to be sucked away.
