Versatile Mage: I Rely on the Demon Locking Tower to Become a God

When Bei Shi was fifteen years old, the Bei family threw him into Changbai Mountain. The snow was so heavy that it was hard to see when the owner of the house left. He fell in an unknown place, the moonlight fell on him, and something in his body woke up - summoning system, forced contract, intermediate level, all in one go. He woke up to find himself lying in a tower. There is an old voice and a gentle voice living in my mind. There is a warm white broken horn on the neck. The thunder and fire priest said he was pitiful, and the grass and tree demon said he had a hard life. The big monsters in the tower pushed him to the middle level, but the price was that he could never return to the world of ordinary people. He could have died in that snow. But he didn't. Later, he walked out of Changbai Mountain and met a man named Ai Jiangtu. The man asked him: "Where did the fire in your hands come from?" Bei Shi thought for a moment and said, "Shan gave it to me." Changbai Mountain left him behind. He had no intention of leaving. He was abandoned by his family, but was picked up by a group of demons.
