Manipulating the nanomachines with a delay was a very frustrating experience. Sometimes, even when the brain's thoughts were clearly ahead, the nanomachines would still have a moment's delay before they reacted to the commands.
The hands would not listen to the head, and that made Wang Yuchi and the other students feel like they were mentally impaired.
If they could control the nanomachines better, they would probably be of great help to the group. But in reality, they were powerless.
So when Ren Xiaosu told them that physical exercise could help increase their synchronization rates, the students who were not injured started taking the initiative to do more work, while those who were injured thought of ways to train themselves. For example, those who had leg injuries would train their upper limbs, while those whose arms were injured would train their abdominals. If a person really wanted to succeed, they would think of a thousand ways to achieve it.
