"Heartbeat Source Project" Zhou Xiaoshan entered the source project as a commercial spy. Zhou Xiaoshan is the hero of this play. He said he had a purpose when he first entered the source plan. Getting close to Qiu Jianing is also Zhou Xiaoshan's last task as a commercial spy, stealing intelligence sources. He reached an agreement with Uncle Cha, and after this task was completed, he and his mother lived a normal life.
After Zhou Xiaoshan entered the source plan, after the first test of the source plan was successful, he stole the formula quietly without revealing his identity. Qiu Jianing believed that Professor Harry was responsible for the recipe leakage from beginning to end, and was willing to bear all the consequences, so he turned passivity into initiative and decided to re-formulate the source plan. As the saying goes, many things grind, Qiu Jianing once again made a new source plan, and this component of R&D expenses was also cancelled.
Zhou Xiaoshan's death is somewhat regrettable. Because of the appearance of a new formula, the formula that Zhou Xiaoshan stole for the first time is useless. After receiving the instructions from Uncle Slag, he is going to steal the formula again. At this point, Zhou Xiaoshan already knew that his mother was dead, and he didn't want to be intimidated by Uncle Slag, so he decisively refused. For various reasons, Zhou Xiaoshan had to return to City A again.
After Zhou Xiaoshan returned to City A, he would rather go on a hunger strike than betray the source plan. In desperation, Uncle Zha invited Qiu Jianing to City A and threatened Zhou Xiaoshan with his life. However, in order to protect Qiu Jianing, Zhou Xiaoshan finally took Uncle Slag hostage, and caused an explosion by himself, and died in the explosion with Uncle Slag. In order to protect Qiu Jianing, Zhou Xiaoshan did not give up his life. Unfortunately, the hero and heroine are not together at the end of the story.
The source plan has been successfully developed. Zhou Xiaoshan protected Qiu Jianing with his own life, and at the same time kept the source plan from leaking out. At the final press conference, when the names of R&D personnel of the source project were announced, Zhou Xiaoshan's head also appeared on the big screen, which made Qiu Jianing very pleased.
When Zhou Xiaoshan's head appeared on the screen, many people thought that Zhou Xiaoshan was not dead. However, contrary to expectations, there are some regrets at the end of the TV series, but the success of scientific research has brought hope and comfort to all cancer patients.
