After reviewing various pieces of commonsense knowledge, Du You had to spend a considerable amount of time preparing for skills. The blueprints that had been hanging on the Magic Network had yet to be traded away.
When Du You inspected his territory, he discovered it was still slightly short of reaching tier four, but he was far from having enough Crystal Coins, so he needed to obtain a batch of them.
"It seems I can only consider selling the two sets of blueprints, and if so, I will sell them," he decided.
Unable to exchange the blueprints he needed, Du You inevitably chose to sell them. Exchanging them had always failed, but selling them proved to be very easy. As soon as he changed the title and fixed the price, it was adjusted several times.
By the end, Du You had accumulated over four hundred thousand Crystal Coins, though none of them were exclusive coins.
