Shen Xingmian stayed in London for a total of thirty-two hours.
In the last ten hours he did three things.
First, Su Jinse's basic precision control training has been advanced to the point where energy recovery can be completed within five seconds. Five seconds is not one second—but it is very fast for someone who has been awake for less than forty-eight hours. Pei Duo can take over the next training.
Second, I exchanged communication frequency bands with Pei Duo. Private band. Does not go through the Department of Control's system. Pei Duo didn't trust the communication security of the Control Department - Shen Xingmian thought about it but didn't insist on letting him go through official channels. Trust goes both ways. Pei Duo is willing to establish a personal connection with him, which is more effective than any official agreement.
Third, I had a long talk with Su Jinse.
The conversation took place two hours before leaving. In the small room of the stronghold. Just the two of them.
Su Jinse sat beside the bed. Holding the brooch. She had developed the habit of holding the brooch in her hand no matter what she did.
"You have to leave," she said.
"Yeah. Go back to China."
"After you go back - will you come again?"
