Sword and Magic: My Mana Has No Limit

In a time-space rift, an ancient demon clan lives, with members all being extraordinary powerhouses living for hundreds or thousands of years. The top of the continent's power rankings are filled with his older siblings. In this world of swords and magic, each person can only possess one type of mana for life. Only he, with white hair and red eyes, is born with three types of primal mana: red, purple, and black. As the youngest young master of the clan for ten thousand years, he is doted on by the entire clan and is the only one in history allowed to use the family surname. Even his father, the clan head who has lived for thousands of years, admits inferiority and strictly orders him never to draw his sword unless life or death is at stake. Before the age of sixteen, he never trained for a single day, yet his mana automatically multiplies exponentially at all times. The ancient beasts roaming the rift are nothing in his eyes. He always thought he was pathetically weak until the dean of the continent's top academy personally visited, crossing time and space to deliver a special invitation. After entering the world, the naive youth directly tops the special recruitment list, surpassing all geniuses. As various prodigies and peerless beauties are drawn to him, this self-proclaimed weak demon young master slowly unveils his own invincible legend!
