Xia ruofei looked carefully and barely recognized that Ling Qingxue had been repeating the word "pressure".
What kind of pressure? Spiritual pressure? Or was it some other form of pressure?
It was difficult to convey complex information with this type of lip movement.
Xia ruofei was a little regretful that he had not taught Ling Qingxue sign language in the military. Of course, sign language could only convey some simple messages. It could not replace language.
However, Xia ruofei saw that Ling Qingxue was standing on the first step with a relaxed expression and felt a little more at ease.
If it really was spiritual power, then Ling Qingxue still had a great advantage.
