How to upgrade the legendary summoning beast of mir mobile game version?

You need to bring your own beast to kill monsters, let the beast die, and then summon the beast, so as to achieve the goal of upgrading the beast.

The same is true for Taoist priests, and there are shortcuts to upgrading the beast. Taoist priests can run to the side of broadsword guards and then summon beasts in actual combat. The broadsword guard will attack the beast, and it will all be solved with one knife. Taoist priests can constantly summon, and they will soon be able to practice to the seventh level of God beast.
