The real world merged with the game world, monsters came to the world, and herds of beasts raged in the city.

In order to eliminate monsters in the dungeon, everyone who has player qualifications has to hunt monsters, choose a career, keep getting stronger, and protect human cities from being destroyed.

Elemental mage, fire and ice, destroy everything! In the priesthood shield battle, Mount Tai collapsed in front of him and remained unchanged.

However, Han Yu, who had high hopes, chose the summoner profession that even dogs would not choose.

“Summoner? Is there anyone for this profession? Don’t dogs even play?”

“Who will team up with a summoner, let him brush slowly by himself. The two summoned creatures are not enough for me to step on.”

“I heard that his talent is not bad, why can’t he think about it so much, and changed his job to a summoner.”

Until one day, Han Yu was drinking tea while standing behind Huyun Leopard, which was the size of a mountain, and the giant skeleton hand that emerged from the ground gently pinched the boss to death.

Only then did people discover that Han Yu’s summoned objects would not disappear, and could even be cultivated continuously!
