Lightning Is the Only Way

"Oh, what do you have for me this time?" asked the clerk behind the counter in the Exchange Hall as he looked at the corpse Gravis was carrying.

THUMP!

Gravis put the corpse down. It was a two-meter tall, yellow mantis. Like all the other beasts he had killed in the last week, this was a middle-grade demonic beast. He needed around two days to complete one mission. It wasn't that the missions were hard, but that the way to the mission areas was pretty long.

The missions came from all over, and Gravis had to travel to those places on foot. He ran pretty fast, but it still took some time. He was running for hours on end, ending the fight in one exchange, and then running for hours again. This was boring Gravis immensely.

Gravis was waiting while the clerk looked over the corpse. After a thorough inspection, he walked behind the counter and took out some money. "As always, an incredibly well-preserved carcass. I'll give you 85 gold for it."

Gravis nodded and took the money. He didn't care about haggling on the price, since that was only a small amount of money to him. As Gravis walked out of the Exchange Hall, he counted his money. "Three missions with 100 gold each as a reward. Another 210 gold from the corpses. With my ten gold from before, I should have 520 gold now."

Gravis pondered his situation for a while. He could finish upgrading his Lightning Seed with only 50 gold, yet he would need 2,000 gold to upgrade his Lightning Seed to 40% Destruction Energy.
