Even seven stars are like this, let alone nine stars or even the fourth rank.
In fact, up until now, Su Yu hasn't formally held a ceremony for mechanical creations. He has the related knowledge, but hasn't practiced it.
Su Yu obtained some mechanical blueprints from those mechanic descendants, such as the blueprint of the Giant God Soldier Mecha, which includes a complete ritual.
However, those rituals are complex and troublesome, and not as simple as the ceremony he conducted for his own advancement.
It's still more convenient to "take shortcuts."
As long as you find a way, you can bypass this ritual restriction.
For example, Su Yu's Brutal Battle Armor back then, although powerful, was not fundamentally third-order.
At that time, Su Yu had just advanced to Ghost Hidden Blade, he was not a Seven-Star Mechanic, and did not have the ability to create third-order battle armor.
The real third-order aspect of the Brutal Battle Armor was actually the Brutal Core.
