The MC should create his own crafting guild (alchemy, scripture etc...) with his knowledge. He could thus make Glory city more powerful (especially his family) while having 100% control over the source of distribution (currently whatever the MC does he will not be able to control those that already exist). It would be a shame to leave the weak city behind like Nilie did when he left for the Dragon Ruins.
Man, in 3 months he only reached 24? this garbage? Nie lie with Heavenly Fate Techniques in 2 months already had the strength of almost silver. You're just nerfing the mc so much. His intelligence basically boils down to yours, because you said it was a technique that practically rivaled the top 3 (I understand that he didn't take the pills that Nie Li did, but still the guy practically has resources to spare with his family) , in addition to the fact that Nie Li was an Emperor level expert in cultivation, that alone already raised the mc's Qi (Nie Li in the work was only dumb for the author's convenience). Not criticizing the author, but when writing in the future, you have to create the scenario first on paper and then write it in the book (I tried to create a ff, but it was really bad because I just wrote without thinking).
