To retaliate against Su Man, Su Nian secretly leaked the weak points of Ling Yuan's seal, colluding with the capture team of the Sea Clan's imperial uncle to raid the villa, intending to kill with a borrowed knife. At the critical moment, Ling Yuan, whose seal had only thirty percent of its power left, revealed his true merman form, and Su Man drove a mecha to fight back fiercely. During the battle, the two triggered a symbiotic contract with interconnected powers, and Su Man successfully repelled the pursuers using deep-sea aquatic combat power. After the battle, Ling Yuan confessed that his three hundred years of forbearance and active imprisonment were all to wait for Su Man, his destined symbiotic partner, and he had been charmed since their very first meeting. Meanwhile, Su Man, hiding high above, witnessed everything from start to finish, her jealousy driving her completely mad.
