"Yes, but I'm just suspicious. It could also be someone else who has a grudge against the Tang family," said Leng Xiaoyao. Without evidence, she couldn't conclude that it was related to Tang Lei. She could only say that he was the prime suspect.
Whether it was related to Tang Lei or not, what he did was enough to get him imprisoned for life, or even sentenced to death.
"Grandpa, it's not safe for you to stay in the hospital any longer. It's even more dangerous to go back to the Tang family's house. You're fine now, so let's just leave the hospital and you can come to my house with me! Tang Xing and Tang Ning will be very happy to see you," Leng Xiaoyao said. Although she arranged for protection and surveillance, Tang Lei might bribe the attending physician to tamper with his medication!
Old Master Tang was indeed fine, and there was no need to continue to be hospitalized.
