In the Three Kingdoms with a System!

Late at night,

Lu Bu: Chan'er it's for the greater good! Plus, these rebels are content with Ma Ai and the way he treats them! that's why they want a new lord.

Diao Chan: this was a new start not to be a lord but for our family! But I won't argue just make sure my precious baby lives from this since your taking him with you!

Lu Bu: I won't let anyone kill my son!?

Lu Bu: thank you for understanding Chan'er.

Next morning,

Lu Bu: Tianlong!!Yes, father!? Saddle up grab your spear and don your armor we set off at sunrise!!

Tianlong: its finally here huh? The day my father takes his first step in becoming a lord! System host has received 3 missions! [ Slay 200 enemies] [slay one captain] and [stay alive to witness your fathers or his generals fight the commander] Rewards [ Medium spear proficiency], [ medium horsemanship proficiency], [1000 army building points and 1 gacha ticket] System how many will be participating in the war?

System: approximately 40thousand shall be participating 20thousand both for each side.

Tianlong: why am I in such a huge battle for the first time!?

System: this is normal for an uprising against their lord as they are either mistreated or malnourished and from seeing how your father treated them, they vie for him to be their lord meaning an uprising shall happen to put your father as their lord.
