I think that Jiang Li would have become a great cultivator even without the system as Jiang Li uses his brains very much. ..... ... Also the responsibilities he bears are great too for a person like him who has started his journey not long ago. .. ...
Man, you put Jiang Li on a very high pedestal just for being from the earth. Do not underestimate the intelligence of others based on this. Also, you said that he would use his intelligence to progress and now you talk about the luck of the protagonist, which is totally different from your original comment.
BloodPunisher:You are really thinking about Jiang Li on the same wavelength as ordinary peoples. Don't forget that Jiang Li was from Earth. He would've introduced advanced mechanisms of Earth to Cultivation world and get enough resources with money. Also, MC's have plot armor that's why they are very likely to stumble upon secret realms.
