The northern barbarians affair involved frontier military affairs. Before delivering to the Grand Council, the commander in charge of the Black Tiger emblem could look through it first. The booklet handed by the barbarians was very sincere. It carefully described the Third Prince and who his servants and followers were.

The Third Prince was only fifteen years old, he was said to be sick and frail. They were accompanied by an ambassador translator, ten young male and female slaves and twelve guards escorted them. Everyone's names and backgrounds were clearly written, even the age of the slaves and their supervisory duties were listed in detail. They strictly followed the passing-through regulations of Great Liang. Gu Yun looked over it three times from beginning to end, but did not see anything out of order.

Shen Yi said with his arms crossed on the side, "It seems that it is true, the ambitious Second Prince imprisoned his father and brother, even chased his younger brother away to be a hostage, making it easy for him to overtake the Eighteen Tribes."

"What's the advantage of dominating the Eighteen Tribes?" Gu Yun threw the document aside. He sat by the warming stove of the camp tent for a long time but was unable to warm up. At this time, he still intentionally or unintentionally put his hands close to the heat source and rubbed them gently. "If they were defeated this time, the Barbarians would not be able to fight back. Every year, the amount of Ziliujin they dig up will all have to be sent over as tribute, even the goddess and the Wolf King's daughter cannot be protected."

The feuds between barbarians and the Han people in the Central Plains were not something from just a day or two ago — as early as several dynasties ago, the nomadic people in the north had the custom of barging down south to rob when the year's harvest was not good.

The north had the fierceness of its strong people, the south had its many famous generals. Both sides had been in a stalemate, neither was able to conquer the other for a hundred years — until Great Liang took the lead in developing steam technology.

The scenery of those years, people could only get a glimpse of it from the records of history. It was the golden age of the Mechanics. The fertile land of the Central Plains was like a giant monster awakened from its slumber, iron armors springing up like bamboo shoots after a rain, Light Suit, Heavy Armor, Giant Kite, flying Eagle and so on. Thick steam rising like a tide, iron puppets spreading across the capital, the range of long and short artillery was changing with each passing day.
