Summoner War: Only I Summon Ancient Beasts

The summoner's world is filled with thousands of races! Others awakened the summoning technique and summoned the ancestor of vampires, the archangel, and the Demon King. All of them are legendary beings who are admired by thousands of people wherever they go! It's Han Dong's turn to awaken, but he can only summon wild beasts? ! Just when the entire Internet was laughing at him as the most useless summoner, Han Dong summoned a group of ancestor-level beings—— On the left, there is the ancient wolf that once killed gods in one breath, and its ferocious power shocked the three realms; on the right, there is the Yamata serpent that can swallow mountains and fill the sea, and the poisonous mist fills the sky; above the head, the golden crow of the sun spreads its wings, and the golden flames burn up and the space is distorted; behind, the ancestral dragon that has eaten the roots of the world tree raises its head, and the dragon's power makes all races kneel down! At this moment, there is an army of gods and demons hostile to the Summoner on the left, and on the right there is an alien symbiote army that is about to break through and invade. Han Dong stroked Sirius' mane, his eyes as cold as frost: "Since you all want to die, then-" "Let the war begin!" This novel and its characters are purely fictitious.
