Before the City University experience acceptance test, Lin Che discovers his campus restoration project has been submitted by Qin Jing as original. Su He produces records but admits cutting out the failure; after finding the original footage, Lin Che not only retrieves evidence of contribution but also discovers the collapse was related to his own operation. The old cloth bag is repaired and jams again, shattering "done means finished." He discontinues unverified supports, publicly discloses temporary handling limits, and lets classmates test. Qin Jing corrects the statement, the team gets a small-scale trial run opportunity, and both contributions and unfinished responsibilities are explained.
