Having a good start is essential to the game. Here is the Chaos of Three Kingdoms guide of the walkthrough from Level 5 to Level 15 shared by Tsang from Official Forum. If you just started this game, check below to get the information you may need:

1. Development of Base

Before you complete the Turbans. You can only upgrade your level until Lv 10. Time to be used for each building is very short. So upgrade each building to max at this stage is strongly recommended.

2. Enhancing of Equipment

Before your base level reach Lv 16, the MP for enhancing will always stay at 100%. It is strongly recommended that you would upgrade all your equipment, especially the green equipment to lv 15 before you go beyond that. In Changse map, One of the NPC will give Ingot Blade while there is another NPC gives a green armor. Try to obtain those and enhance it to Lv 15 (Average Lv 5). Please be noted that the level of your shop, which determines the max equipment level of your equipment enhancement cannot be higher than your base. That is why i suggest to enhance to Lv 15.

3. Recommended Heros

Here is the hero that I will recommend to obtain in the first 2 maps:

1. Guan Hai
Skills: Clean Swipe (Attack All Tactic attacks)

2. Sun Xia
Skills: None

Sun Xia is a mechanic units and can give powerful common attack at the beginning stage. Will be your main Force at the beginning stage.

4. Development of Building

From Level 11, you will have new buildings coming up as follows:

Level 11: Granary - Determines the amount of food that you can store. Food is used to recruite soldiers. However, no soldier is needed to be recruited before lv 15. So try to fight as much campaign as possible in campaign at lv 14 since you don't have the problem of not enough food for recruiting soldiers.

Level 12: Arcademy - Arcademy is where your war technology develope. At this stage, try to spend some time to get upgrade your formation to lv 2 and maximise other tech.

Level 13: Market - You can buy and sell your food in here

Level 15: Barracks - Recruit your soldiers
