The ticket for Zhang Te's mother was held by the boarding pass checker, deliberately not scanning it immediately.
Zhang Te knew that the mastermind was doing this to ensure that they secured "Han Jingnian" before letting his mother go.
Without hesitation, Zhang Te stepped into the bar. The moment the automatic door closed behind him, he saw on his phone screen that his mother had received the checked ticket and was boarding the plane.
His mother was merely a tool to threaten him in the eyes of the mastermind. Neither he nor his mother mattered to them - what mattered was Han Jingnian. Now that they thought they had "Han Jingnian", they naturally wouldn't continue to trouble his mother. On a plane filled with passengers, no one would dare to act rashly. And once his mother reached their domestic airport, the people he arranged would pick her up... Either way, his mother was at least safe now.
