Building a Conglomerate in Another World

This author has a novel called "Creating an Industrial Empire in 19th Century Parallel World". This novel and that almost the same as story wise. I am at 29th chapter so i will give spoilers until that chapter as a basic explanation. Also it will include spoiler from other novel just for comparison. An engineer goes back in time paralel world. Its paralel in name only. America is Ameritha, Tesla is Volta etc. other than that everything is the same. That engineer sees trains brake system is bad and invents(copies) better one. Makes money and goes on more businesses. At this point after train brake system, he goes for car. For making car bussiness he also goes for petrol/oil bussiness. In other novel that i mentioned, its the same story slightly different. Rather than one MC there are 2, and rather than black racisism, there is silver hair or something racisism(i remember the reason why silver hair people are treated bad but anyway). In both story, MC(s) goes to a banker for money and investment reasons and so on. I liked that novel so i started this one and this one also goes with same quality but after reaching 300+ chapters, author just stopped for that novel and started new ones. So even tho he finished his first novel "Reincarnated as an Imperial Prince", he doesnt intent to finish other good going novel. So at this point i dont trust that this novel will keep the steady updates cuz he has many novels to update. TLDR: This novel has 70 chapter so if you want more go with "Industrial Empire" one cuz it has more chapters and its the same story.
