Upon returning to Tianhai City, the first thing Yang Yu did was buy a bunch of pigeons and then train them.
Although the territories of Huang Shiyin and Wu Qiong could cover most parts of Tianhai City, people are bound to make mistakes.
So, to make up for this "mistake," Yang Yu thought it was necessary to use these pigeons.
Aside from that, Yang Yu went around purchasing materials for making Mechanical Armor.
With enemies in the shadows and himself in the open, to protect everyone around him, besides essential bodyguards, Mechanical Armor was indispensable.
After all, Mechanical Armor wouldn't die; it could shield people from knives and bullets.
This time when Yang Yu returned from Fengyang Mountain, he learned that Mechanical Armor could also be equipped with runes, so it's fine even if the person needing protection doesn't know the Mechanical Armor Technique.
