Call of All: Summon Thor Baalzeb at the beginning

Upon waking up, Bai Xuan found that he had traveled to a world of summoners. In this world, top experts can explode stars easily, and mythical level summoners can even create small worlds.
As a cute new summoner with extremely poor potential, when he saw that other people's summoned creatures were fantasy races, such as dragons, elves, demons, angels, etc., Bai Xuan admitted that he panicked!
Fortunately, when the call was made, the system was successfully launched, and then...
"Ding!Congratulations to the host for summoning the seven rulers of the world—the god of thunder Balzebub (Ray movie)』
When he saw Yu Jie in purple kimono with lightning eyes, the corners of Bai Xuan's mouth rose wildly!
From then on, with the help of the system, Bai Xuan embarked on a unique path as a summoner.
Your dragon is very powerful?Why don't you take a look at my British foodie Red Dragon?
