He comes from the firelight. In which episode was Simon crushed?

25 episodes. In the 25th episode of TV series "He Comes from the Fire", I saw that the house of the interest class collapsed because the construction workers pushed down the load-bearing wall, and the teachers and students were trapped to see the fire truck coming and returning to rescue the students in the ruins. Yu determined that Vivi was temporarily safe in the ruins, chose to save another student in danger, and then returned to rescue Vivi again, but it collapsed for the second time. In the end, after hard work, I rescued Vivi, but Milan was angry that I didn't rescue Vivi at the first time and took Vivi to the hospital alone.
