Su Chen transmigrates into Arknights and becomes Theresa's strategist.
As a transmigrator, he knows that if Kazdel is to be restored on Terra, they have to hold on to two principles: play it safe and keep a low profile.
In the year 1087 of Terra, Theresis declares himself King of Kazdel. Su Chen advises Theresa, "Build high walls, stockpile grain, and wait before claiming the throne."
A year later.
"Su Chen, we've built ten cities and gathered a third of the Sarkaz population. Can we fight Theresis now?"
"Not enough. We need to win over at least ninety percent of the people before we have even a little chance."
A few years later, Theresis is in decline, and ninety percent of the Sarkaz people have given their hearts to the princess.
Theresa: "Su Chen, can we finally reveal our hand this time?"
"No. At the very least, we need all ten Royal Courts on our side."
"We already have seven. If we set aside the two that have vanished, only the Cyclops in the north remain."
"No. We can't leave even one out. We have to play it safe and win the Cyclops' support first."
Theresis: "Have some mercy! I've surrendered twice already, and you still want to get all ten Royal Courts together to take me down."
