Legend: He Just Became the Skeleton Emperor and Was Summoned by His Daughter?

Three years ago, Gu Yuan was reborn in the legendary world and became an extremely short skeleton in the Skull Cave. When he was desperate, he discovered that he could actually level up. Gu Yuan immediately began the path of upgrading a heterogeneous skeleton. As he continued to kill monsters, he grew up again and again, and finally became the BOSS-level Skeleton Emperor. On the day he ascended the throne, suddenly, the Red Moon Demon joined forces with many bosses to arrive and banished him to a dark space. Gu Yuan thought that his life was about to end, but he was summoned back to the real world by his daughter Gu Ling, and became his summoned skeleton. At this moment, Gu Yuan knew that the real world had been eroded by the legendary world and entered a disaster. His family was killed and his daughter escaped, but was bullied. People around him mocked and even actively provoked Gu Yuan. Gu Yuan raised the ax in his hand, gave it a light blow, and the killing began! Everyone is confused! Gu Yuan: Anyone who bullies my daughter must die! Those who harmed my family will also die, and those bosses who teamed up to plot against me will also die! From this day on, Gu Yuan began to pave the way for his daughter and take revenge with her. Countless strong men roared in terror. The thick-blooded warrior was instantly killed by a summoned skeleton? A powerful mage, magic damage can't kill skeletons at all? A Taoist priest and his dog were chased and chopped by a skeleton? Even the BOSS looks like a rookie in front of the summoned skeleton?
