Old and new Zhu Huan Gege Gan Long met an assassin while on patrol. How did Gan Long escape, because some situations were invisible?

The new version of Princess Zhu Huan: At the fire festival in Qijiang Town, everyone broke up intentionally or unintentionally. Suddenly, Bai Lianhua assassinated the emperor, and Wei Zi gave his life to protect her, and the dagger went into her chest. Local officials arrived in time and Wei Zi was handed over to the government. Dr. Hu wants to draw the sword and send Ma Feisan to live longer. Before drawing the sword, Wei Zi asked the emperor that no matter what the swallow did wrong, she would not die, and the emperor agreed. The knife was pulled out, spattered with blood. The swallow fainted with sadness. Er Kang decided to take Wei Zi away, and Ban Mingjie reminded him that he had obtained "Amnesty" before he was persuaded to live. The emperor was shocked by Wei Zi's feat, and Ji Xiaolan agreed to give her a seal.

Princess Zhu Huan: One day, a group of people were watching in a crowded market. Wei Zi and Gan Long met an old couple selling tea eggs. Suddenly, they pulled out a pre-stored short knife and stabbed Gan Long. Suddenly, the situation changed, and people in the city became assassins, often attacking Gan Long. Wei Zi saw the emergency, desperate to find a knife for Gan Long. However, Wei Zi's weak body was greatly hit, and she fainted at once. When Qianlong saw this, he was frightened, and Erkang was even more worried. He quickly grabbed Dr. Hu for treatment. Wei Zi finally narrowly missed this difficulty, but Er Kang saw Gan Long's careful care for Wei Zi and the faint love in his eyes, and Wei Zi's injury gradually recovered under everyone's patient care.
