"Tsk tsk! As expected, it's really expensive. However, the knowledge I'll gain is worth the price."
The underground shuttle was the most cost-effective out of the given selections.
Fortunately, he had accumulated a lot of points during, so he proceeded with the exchange.
He had to read and understand the system's information on his own, so he could only stay in the Divine Forging Space to learn.
The time ratio between the Divine Forging Space and the outside world was 10:1. If he spent all his time on studying, he would save more than 20 days on studying if he was given half a day to draw.
The underground shuttle naturally came with its own blueprint, but it was a seven-star Divine equipment comparable to Thor's Hammer. It was not appropriate for him to just bring it out.
Therefore, he needed to understand the blueprint thoroughly and simplify it.
