The journey of the group is basically smooth sailing as the presence of the Qilin and Kanlaon combined. The flying monsters that could attack them are those that are dumb or are really hungry. Saru easily swatted those monsters as they were only unintelligent monsters.
They headed north of Mt. Thunder since the House of Creation is located in a tall mountain in that location. The House of Creation is the most mysterious of all the houses established in the eastern continent as they are not affiliated with any of the holy beasts.
They did not affiliate themselves with the holy beasts because they are strong just by themselves. Ryujin that are said to have unlocked the knowledge of the elements are all members of the House of Creation. Even the direct houses under the protection of the holy beasts dare not to mess with any of them.
