Rolling (the panda MC) transmigrated to the interstellar eea after being killed by poachers for his fur. The ML (forgot his name) is some big shot admiral that got into an accident/was betrayed (i dun remember what happened to him) and landed in a primitive planet.
ML was dying when MC saved him by giving him water (somewhere along that line) cuz he dun have the energy anymore so MC giving him water made him recover some strength to move. ML is very grateful the Rolling who was only a baby panda in the start.
MC was first very afraid of ML cuz he looks like the poachers who killed him but he soon opened up when ML started giving him food.
First time MC turned into a human, he turned into a baby.
MC have special powers of yin and yang and can see spirits. All panda have this ability so they went extict. Somebody hunted them down.
MC have guardians, the soul the the diseased pandas protecting him.
Aaaaand the last part i read was MC and ML discovered a cave where the pandas was slaughtered.
BTW, MC's growth in his human form is very fast. First transformation he was a baby then a few chaps later he can already run. But still a baby. A toddler to be exact.
