Ken already tried to summon healing pills from his storage ring but failed, indicating the space was locked and storage rings were useless there. He tried to use One Step but failed again, so he was sure using techniques was banned in the long corridor.
He faced the second man that charged at him. It was another man in the low phase of his stage, and Ken used the lower part of his flexible sword to block the man's swing while the upper part of the blade bent from the momentum, curving toward the attacker's shoulder.
"Ah! It's flexible!"
The man shouted in pain as Ken's sword sent a pulse of dangerous Sword Qi into his shoulder, rupturing his muscles and trying to fracture the shoulder blade. He retreated to let his teammates take over the battle, while he stabilized his Qi.
