Of course, that was if he didn't wake up to find that he had used one of the Marquis of Order's arms as a pillow all night, causing it to go numb, and not only that, he was even snuggled deep into the man's chest.

Especially Gu Yun, that shameless bastard would never understand the sensitive and emotional heart of the still-growing young boy. The more self-conscious the other became, the more he would pour oil into the fire. Marshal Gu believed that since they had shared a bed for the night, Chang Geng had already reconciled with him, thus continuing his bad habits. He rubbed his numbed arm and teased the boy as his morning entertainment, and it even appeared like he would remember this to always bring up again in the future.

Was this person's ill and weakened appearance from last night just an act again?!

In the early morning, Shen Yi saw Chang Geng angrily stomping out of Gu Yun's Marshal's tent, blushing red. For the rest of that day, he would turn the other way as soon as he could see Gu Yun.

On the road, Shen Yi ushered his horse over, glanced at Gu Yun's face then asked, "Is everything alright now?"

Gu Yun, like an old wolf, proudly said without care: "Just a little kid, such trivial matters. There was nothing in the first place."

Shen Yi had witnessed Gu Yun spin around with concern and anxiety during the previous two days, he was at a complete loss of words and could only sneer.

Gu Yun as per usual pretended he couldn't hear, watching Chan Geng’s back from far away, he suddenly spoke: "Say...can I leave the Black Iron Camp in his hands down the road?"

Shen Yi dryly replied: "You want him to meet a tragic demise?"

Gu Yun made an irritated sound as if Shen Yi had just killed his mood.

"Do you really think that the Black Iron Camp is a nice thing? I am speaking honestly, Zi Xi, pardon me for saying these words that are difficult to hear," Shen Yi said: "The Black Iron Camp in the hands of the old marquis, was a 'weapon for the country'. But when handed to you, it became a 'weapon against the country'. A weapon for the country is radiant, favored by many, the same can't be said for a weapon against the country."

Hearing the meaning behind his words, Gu Yun's lazy smile disappeared.
