Inside the beast's bone was a leather map, with a spot marked X in blood detailing ruins that seemed like a series of catacombs. He had encountered ruins, but not large and notable ones like the ones detailed vividly on the beastskin. The other item was a bronze key, with World-crusher etched on it, and for someone who comprehended laws, a crushing strength law was etched on the key. This now got him curious.
"Since this giant was headed straight ahead, well, in danger, there are great opportunities, might as well try my luck."He first recovered his energy for two hours by absorbing mana crystals, with less than a hundred remaining, and bolted straight ahead, as he always couldn't think straight when resources to enable him find a path ahead were involved.
After about three hours, the key vibrated, and when he stopped and held it in his hand, it suddenly tilted and pointed northeast, just a bit off to the east to where he was headed, and he suddenly let out a crazed laugh, as he followed the key, his previous calm demeanor gone, replaced by a crazed swordsman laughing.
As he approached some ruins, similar to the previous ones, the key shed its rust and transformed into a pure silver sheen, and he knew the material the key was made from as natural metal essence extracted deep from the earth and compressed several hundred,s possibly thousands of times to smelt a key.
He didn't know why it would react like this, as the ruins ahead were desolate, similar to the ones he had seen, but he decided to trust the key and approached the ruins. He then reached and wandered around the ruins. As he was on the verge of giving up and leaving with his expectations destroyed, the ground suddenly gave in, and he fell but landed safely and saw a series of catacombs which looked like the map on the beast skin.
He was incredulous at first, but he knew that even mortal inheritances had some tests, and since giants were physical combatants, he knew that there were body-cultivation focused magic beasts and resources in these catacombs, so he drew his sword and got ready for whatever would come after him. As he was following the beastskin map to the central area, he heard a ghastly roar and felt a peak sixth-level magical beast approach.
