Cold-calling birds, this is the only information transmitted back by Barrel Man Yu Liang, who is stuck in the future time-space, but this guy does not know whether he is unable to speak or just unaware. It's a bit of a riddle on him, making Yu Liang want to sort it out.
Unfortunately, Cold-calling birds are not afraid of him at all, since that guy is not even afraid of death.
As a Strange Story Creature destined to vanish into the future, Cold-calling birds naturally do not care about life and death.
It seems that the whole cruise ship instance needs perfection, and maybe when the instance assimilates the power of Cold-calling birds, it can initially achieve Yu Liang's goal.
Creating a closed time-space, where 'Current Yu Liang' within the closed time-space is merely an experiment, a character [created], used to explore the infinite possibilities within the closed time.
