If I Want to Become a Mage, What Kind of King Will I Be?

Good news, you traveled through time. Changsun Sheng opened his eyes, and he became the third son of the king of Weiguo. Okay, at least I have obtained the official establishment, and there is no need to take the public examination. Bad news, the system told Changsun Sheng that someone wanted to kill him. Let me go, what the hell system. Other people's systems either send out exercises or tasks, which are awesome and can directly start the game at full level. This is good for him, there are just a few words stamped on it, and he also gave himself a bottle of poison. What the hell, do you want me to take poison and start the game again? After finally passing the test, I thought I was about to embark on the path of leading the country to rise and dominate the world... So miracles and magic really exist? ! I don't want to be a king anymore, I want to be a mage!
