This is bad. The TL is bad, the plot is bad, the characters are bad, and the art is bad.
MC never goes through struggles, never thinks about his actions, he just exists in this perpetual state of being the best at everything because his magic book gave him magic cooking powers and magic kung fu powers, hardly anything else, he rarely even uses it. The very premise of the series, the magic book, is hardly ever used. Everybody else just bends in awe as he effortlessly wins at everything. Characters are introduced and are dropped almost as soon as they get some slight (and i mean very slight) depth for seemingly no reason other than they MIGHT interfere with the MC being the best.
I have read hundreds of trashy isekai and this, this by far takes the cake for the lowest possible effort wish fulfillment and I regret wasting my time.
There is no catharsis here
I cannot stress enough that there isn't even the illusion of substance here. While most trashy series are trash because they copy a tried and true story from something that did it better, or the structure, paneling or art is sub par, this one series fails on the most basic of basics: There's just nothing.
