Since the Heavenly Dao Palace managed to withstand the attack of those creatures, the Galactic Empire wasn't defeated too badly. They at least managed to guard the gateway to the Northern Expanse Galaxy. But for Darth Vader, merely holding it isn't enough, especially when it's being defended by someone else's forces rather than the army of the Galactic Empire—it's not like they're obliged to risk their lives here with you every day, right?
So we have to rely on ourselves!
The Galactic Empire, being a military system, began operating to its full extent.
The first step was to upgrade weapons and armor.
Luke also provided many of his own suggestions.
"We need stronger, more powerful armor; the current armor is basically plastic and cannot withstand those creatures' attacks at all!"
"We can't just rely on guns; they're fast and excel at close-quarters combat, so we need to enhance our soldiers' melee combat capabilities!"
Darth Vader also received some advice from Fang Zheng.
