Chang Geng: "You want to go back to the Northern Frontier?"

Gu Yun nodded.

Chang Geng: "When?"

Gu Yun: "...Very soon. "

Gu Yun's 'soon' basically meant to leave at any time according to the development of the Western enemy and the damage of the Jiangbei naval army. If he felt that the situation of the Jiangbei garrison was alright today, he would leave during the night. If there was anything that still required adjustment and deployment, he would make orders through the night and leave the next morning.

Chang Geng: "What will you do then? Will you run back and forth between both ends?"

Gu Yun was silent, it seemed that he had acknowledged it.

He suddenly felt he was at fault with Chang Geng. On the way to the western regions that year, Gu Yun once vowed to Chen Qing Xu that even if Chang Geng would go mad in the future, he would still take care of him until the end. But recently, he was always secretly worried how one day, he would no longer have enough strength.

Gu Yun was not afraid of sickness, old age, and death. General Zhong's praying hall was on the side. Thinking about it now, no matter how kind or malicious the elders around him were, those who once taught him, harmed him, were all gone. He knew that even the heroes of the world could not escape such things. People didn't have to be so aggressive with themselves, he was only afraid that he couldn't protect this little madman all the time, on the contrary, even making the other feel more tired, more burdened.

Gu Yun's deep and sincere apology left Chang Geng feeling at a loss for a moment. At first, he was unable to respond to it. For a long time, he realized that someone had carved out a gap in his heart, blood inside was pouring all over, unable to stop.

His heartache was difficult to repress, he could only pretend to smile happily.

"Alright," Chang Geng said in a light and not excessive tone. "Don't worry. Have you seen the drawing I put in your clothes? Soon — after you finish cleaning up the Barbarians, maybe all the steam rail trains on my side will be finished building, do you believe it?"

Soon, he would be able to build up a Great Liang with four sides at peace. Perhaps at that time, the three factions of Black Iron Camp only needed to guard the entrance of the ancient Silk Road to maintain trade order, or simply open up wasteland in the border collectively. Whether his general wanted to drink grape wine at the border or to return to the capital city to fight with birds, he could take all the time he needed, he would no longer have to rush to be on the road, or be exhausted with so many things.
