The Useless Prince's Invincible Beast Legion

Shen Yan transmigrates into the body of the neglected and useless Seventh Prince of the Great Jing Dynasty, exiled to the miasma-filled Misty Hidden Village. He accidentally learns the ancient 'Spirit Summoning and Body Tempering Art' and masters the shamanic power to control beasts. He befriends Lingxi, Bilian, and the Iron Sky Bear, forms a beast legion, ventures into Spirit Herb Mountain to find the main ingredient for alchemy, and joins forces to fight against the monopolistic and corrupt Huichun Hall, steadily advancing to reclaim all blood debts from the imperial family in the capital. — Description from novelcodex.org
