I Can Understand Magical Powers

Chen Dao woke up from the pain and found himself in a dilapidated Taoist temple. There are demons and demons in this world, which are full of dangers, and there are even more cultivators who stay away from the mortal world. When he was running for his life, he accidentally awakened the golden finger, which turned out to be the portrait of the Supreme Lord he bought in his previous life. Entering the illusion, you can experience magical powers and techniques. The magical power of swordsmanship caused the local people to pass him off as a true swordsman. Unexpectedly, I learned that immortal cultivators in this world cannot practice magical powers. But I never thought that there was no way to conquer the devil, but I realized how to conquer the devil. PS: The protagonist's cultivation is different from that of this world, and there is no clear distinction between realms.
