Episode 19 recap: Cheating failure.

The principal pressured Mr. Gao to reveal who else was involved in the cheating, but he stubbornly refused to say anything. This angered the principal, who threatened to expel him from the school. Teacher Lock, who was in charge of strict supervision, noticed something suspicious about a cane and carefully examined it. To their surprise, they discovered that the students had written the answers in Braille on the cane. The cane was immediately confiscated, and the students were disqualified from the exam. The students who had been cheating using bandages on their bodies were also caught by Teacher Lock, who moistened the bandages and exposed their cheating, leading to their disqualification as well.

Upon seeing Teacher Lock's strictness, Yang Defu quickly disposed of his cheating tools and successfully entered the examination room along with Wang Yutian and others. Huang, sitting at the first desk, tried to give everyone a hint as soon as he received the test paper. However, before he could pass on the answers, Teacher Lock singled him out and isolated him from the others. Yang Defu became anxious upon seeing this, but Wang Yutian remained calm because she had already devised a Plan B.

Huang whispered a few words to Teacher Lock and successfully hung an intravenous drip. He used the drip to pass on the answers, while Wang Yutian relayed information to their classmates. Everyone smoothly completed the multiple-choice questions. The following questions were more difficult, and they knew they didn't have enough time to memorize the answers. However, each person had their own area of expertise. Unfortunately, when it mattered the most, they all failed and were asked to leave by Teacher Lock.

Yang Defu and Wang Yutian knew that the class's grades would definitely suffer as a result. They decided to seek mercy from the principal and asked him to pass the entire class. However, the principal did not agree. At that moment, Huang, with the intravenous drip still hanging, made a request as if he were their father and pretended to be on the verge of fainting. This prompted the principal to agree.
