We learned that Qiyu’s number is 2023. Then we need to get the prepared three-dimensional images into the installation package of Han Dynasty Overlord. The installation package can be extracted in the upper left corner of the mt manager.

After extraction, we find the installation package we have extracted in /storage/emulated/0/MT2/apks/ and click to view it.

We found the folder assets/res/generalportrait/ drawn in the game installation package and then renamed the prepared picture to 2023 (note that the format must be png Format)

Then we just long press the picture to add it. Remember to check the automatic signature when adding.
