After he got inside the cave, Alex summoned Anna and Leoz while Sherry also came out. All of them let out a sigh of relief. Their plan was successful.
Alex didn't activate Charya's token because she wasn't needed for the monsters. As for the Martial King, calling her there was the same as killing her.
Alex had confidence in his plan too. Even if the plan failed, Alex had prepared a backup plan. Alex had his Master's token.
According to his Master, the token held his will. He can summon his Master to this world once. After summoning him once, the world had recognized his Master's presence.
This world can't contain God, so after remembering his Master's presence. Even if he tried to summon him again, it was useless. He was relieved when his plan succeeded. That means he can still hold the token for another use.
He suddenly remembered Leoz's report. He turned to Leoz, "Leoz, is that person the one you mentioned back then?"
