Yang Yi unlocked Anton's handcuffs, and then his leg irons.
Anton stood up without the slightest pause, turned, and walked to the toilet in the cell to take a leak.
In fact, Anton could use the toilet with handcuffs and leg irons, but he had to maintain a particularly uncomfortable posture and could only do so while sitting on the toilet.
After using the toilet, Anton carefully washed his hands, then his face, and finally he walked up to Yang Yi and asked leisurely, "Can we leave now?"
Throughout the process, Anton didn't show any abnormal emotions; he just sat calmly, stood up calmly, and then followed Yang Yi out of the cell calmly, without anger, excitement, or any sign of surprise at the prospect of leaving prison.
When Yang Yi led Anton to the cell of the tough guy, Zhang Yong and four others had already lifted the tough guy.
