As a result, I accidentally fell down and was stabbed by a glass bottle and sent to the hospital. According to classmates, Zhao Junfeng looked drunk at that time, but in fact, Zhao Junfeng didn't drink, and Zhao Junfeng's mother claimed that her children had always been normal. Jiao Jiaren hurriedly gave Zhao Junfeng a brain CT and blood test, but nothing unusual was found at that time. Zhao Junfeng is always thirsty when he comes to the hospital. Fang Man gave a lot of water to drink out of kindness, which caused Zhao Junfeng to go crazy again and even injured Fang Man, but he soon fainted and was rescued again.
