National Dojo: a Tea Tree of Enlightenment at the Beginning

[Similar to lord + demon slaying + ghost hunting + golden finger + single or no heroine + decisive killing + daily life] The world of Blue Star is strangely revived. The orthodox sects of various Taoist sects have gone down the mountain to establish Taoist schools to train their descendants to fight against demons and strange things. Lin Feng, an ordinary and homeless otaku on earth, accidentally traveled to the Blue Star. He studied at Maoshan Taoist Academy for four years. After graduation, he was assigned to guard the dojo. He started by killing the first strange monster and activating the Golden Finger Enlightenment Tea Tree. Is it difficult to improve your realm? Killing weird monsters, gaining merit, and improving one's realm is easier than eating and drinking. Is it difficult to practice magic? Consuming Enlightenment Tea leaves, the spell is instantly perfected. Is the formation difficult to understand? Just one Enlightenment tea leaf is needed, and the formation is instantly mastered. Two more tea leaves are needed, and the formation is instantly mastered. No powerful spells? Kill weird monsters, gain merit and deduce spells, and ordinary spells can become powerful special spells instantly. With the Enlightenment Tea Tree, there are no spells that Lin Feng cannot learn, and there are no formations that he cannot understand.
