They said goodbye after a long while of conversation, the sea king easily gave the shell to Ikky, who returned through a portal to the tunnel of the sanctuary. Stopping breathing water was a strange but gratifying sensation, although it had not hurt and he had not been bothered in that underground paradise he could not say that the sensation was exactly pleasant.
He only had one tunnel left before finishing the tests of this energy. When he began to advance through the descending tunnel, Ikky was already prepared to face the test that the developers had prepared.
He advanced for about twenty meters in complete darkness, however a wall prevented him from entering, the tunnel ended abruptly, and in the closing wall there was only a small hole in the wall, it could not be more than seven or eight centimeters, Ikky stuck the spear in and verified that the hole continued for approximately one meter.
