The Northwest suffered a defeat that could no longer be saved. Without the marshal’s order, even if the last soldier died, the Black Iron Camp did not dare to retreat one step back. He Rong Hui struggled to hold them off for three days and two nights, the troops were beaten to the ground, the god-like army created by the accumulation of three generations was about to lose more than half of its soldiers.

At that moment, Chang Geng's messenger finally arrived.

With Gu Yun's private seal, the Royal Highness who had never made himself known or displayed his talents from far away at the capital had imitated Gu Yun's handwriting seamlessly.

He handed two letters in total to the messenger — if the border was still stable, he would give him the first letter, telling He Rong Hui to not be concerned about the court, whether if it was from the black market or other means, immediately secretly fill up the Ziliujin storage in the Western Regions, maintain the armors and be ready for a battle at any time.

In case the frontier’s situation had changed, the second letter would be given to He Rong Hui, telling him he must not sacrifice himself to defense, he must not be eager to fight, and quickly shrink their forces to the east of Jiayu Gate and wait for reinforcement.

The enemy hiding in the dark had already started to move, it was undoubtedly too late now for them to act. There was no Black Eagle in Chang Geng's hands. There were too few people he could get in contact with by the wooden birds in Lin Yuan Pavilion. No matter whether the sky fell or if the earth shattered, the messenger could hardly arrive on time. Therefore, he had envisioned the worst-case scenario and tried his best to mend the cage after the animals had been lost.

If the Western Regions had changed, it would be difficult for the Northern Frontier to take care of themselves. Therefore, General Cai Fen, commander-in-chief of the Central Plains Garrison, would receive another letter from Chang Geng at the same time the Black Iron Camp retreated, asking him to increase his troops to the North and to send his portion of Ziliujin and Heavy Troops to Jiayu Gate as soon as possible to relieve this burning urgency.

However, Chang Geng’s heart was clear. If something really happened, this deployment was not enough.

The hundreds and thousands of mountains in the Southwest were completely out of his control. Although Shen Yi was on that side, he was a commander in name only and had no foundation. It was impossible to arbitrarily dispatch troops without the Drumming Order.

The Eastern Sea Navy was even more concerning. General Zhao You Fang was Li Feng’s man; it was impossible to mobilize that side with only a private seal from Gu Yun.
