1 equipped with resistance to darkness 100 or above and fire 180 (fire attribute plus self-resistance).
2 the blood limit is above 7500 (the merchant buys a little). The strength is above 500 (merchants can buy more if they have money, so that they can fight faster). Sensitivity is above 150 (this can be stolen).
3 skills must be replaced by something (as if they were learned at level 60 or above)
All these conditions can be met. Once equipped with Xuanyuanjian, it will be used to replace the physical form at first (this skill is immune to five attacks), and then it will be chopped flat. If it is not used to replace the physical form, it will be added to the cycle. Refuse to argue.
