Gu Yun watched Chang Geng's ears redden, the blush spreading all over his face. He could not help thinking of Chang Geng's uncomfortable appearance, changing his clothes for him when he had a high fever. At that time, he felt helpless, but now his heart itched incessantly. he thought: Taking advantage of when I broke all my bones and could only lie like a corpse to get touchy with your hands, did you not think this day would come?

Gu Yun asked, "Why don't you say anything?"

"There is no need..." Chang Geng struggled for a long time, grinding his teeth and making up his mind, "I... I also want to look at your injuries."

Gu Yun couldn't help but continue to tease him: "Only to look at my injuries?"

Chang Geng: "..."

Gu Yun's lumbar and cervical bones had problems, Chang Geng did not need to examine carefully because after unloading the armor, he could feel it through the clothing.

He threw aside all straying thoughts and frowned. "Zi Xi, how long has it been since you last took off the Light Armor?"

"Since removing the steel plate, I've been wearing it all the time..." As Gu Yun said these words, he felt that something was not right. After a pause, he quickly added, "Well, of course, I would take it off when bathing, I am not like the bald donkey Liao Ran who likes to be filthy."

Chang Geng reached out and pressed down on his stomach, saying: "Don't move — you still have the heart to mock others."

Even though these generals were powerful at a young age, if they were lucky enough to live until old, most of them would suffer from numerous injuries and diseases. The malposition of the cervical and lumbar bone was almost the norm. Although the Light Armor was lightweight and convenient, it directly added to the human body, unlike the Heavy Armor that could support itself. Gu Yun was always ready for battle, not taking it off even in sleep. For a long time, the bones and muscles weren't able to rest. Chang Geng only exerted a little strength, and with just one press, the cracking sound of his bones and muscles could be heard.

"You can't feel it now, because the muscles of the waist and back can still hold up. What will you do when you get older?" Chang Geng stroked his hands heavily over his shoulder blades and kneaded his stiff shoulders.
