Review Detail of Eternal2145 in Tanky Mage System

it looks interesting since yk a tanky mage, however i had to stop at chapter 3.mainly because there is no proper introduction to mc. all i know is he has a farming system, a "supernatural" book of something, and powerful adoptive parents. what does he farm? idk. what does the book do? idk. who are his parents? idk. ik its about seeming mysterious but why mention it if you will not properly introduce it. it irked me the wrong way. just not for me thats why its 3 stars and not less. try if you will
