Roland spent all his time copying the textbooks after Tilly bid her farewell.
He first started with the basic courses. As he had just got a chance to revisit the knowledge long forgotten, naturally, he needed to take the advantage of it and add the missing information to the textbooks previously drafted based purely on his memory.
Second, he had to improve the designs of the current equipment used in the city of Neverwinter. Roland knew there was still a big difference between an acceptable machine and a good one. A more comprehensive design could further enhance the productivity and efficiency of steam engines and machine tools.
Based on the new design, Anna had finally completed the first steam turbine.
