After reading around 100+ chapters I can only say good things about it mainly. Can't honestly understand the one star ratings below. I will give a proper review as usual so people can understand from my perspective.
The initial story is the usual body possession from a transmigrator and taking over that persons life. This MC is an average mage who got tricked into exile to be a 'lord' by someone malicious towards him for minor reasons. MC decides to make do and farm using his magical knowledge and cheat which allows him to evolve plants/animals by inserting magic spell runes into them. It allows him to make things that can produce all sorts of useful results that can help him make money. This isn't just a farming novel, its also a pet raising novel btw. He keeps his head and always acts mature, never allows anyone to take advantage of him, maximizes benefits, behaves cautiously and fully utilizes his noble mage status without being some pushover. The farming is mainly done in a smart way so its taken care of by others without wasting his own time. He spends his own time developing new resources, meditating, keeping his strength up and territory maintained and enjoying good food and comfort. So don't worry about this guy being focused on one thing and letting his guard down in another.
If there are any negatives then I will say that some people might find the pioneering lord aspect can make it a bit slow. After all, development is the key, and his somewhat exile status is in the form of being a 'lord' on an island. Kingdom building plus farming novels are like that anyways so not much of a 'negative' imo. Aside from that, the luck and fate nonsense that affects Chinese novels also invades this one over time lol. It can be a negative since effort or wisdom of a mage is just a support, but luck is the real factor which sucks to read tbh lol. It can also be a bit repetitive or redundant in the need for planting, farming or taming pets. So I rate it 4.4/5. Its a smart enough MC with good growth.
