From the Start, I Signed a Contract: I Can Contract Divine Beasts Without Limit

[System + multiple female leads + invincibility + battles + transmigration + urban setting + divine beasts + daily life] Gu Wenci is a transmigrator from Earth. A year ago, he unexpectedly transmigrated to a world called the Tianwu Continent, and spent the year gradually learning about it. He discovered that everyone had to start contracting demon beasts upon turning eighteen. The strength of the contracted beast was directly tied to its master's stats: if the master lived, the beast lived; if the master died, the beast died. On the day of his awakening, Gu Wenci was dismissed as useless, yet he contracted a mythical Azure Dragon. Everyone was astonished. Little did they know that, with the help of the System, Gu Wenci had already surpassed everyone present who had contracted a beast during that short year. With the System's help, Gu Wenci grew steadily stronger. The women he met along the way all fell in love with him without even realizing it. But just when he thought he could enjoy a peaceful, carefree life, an even greater trouble came knocking... Many years later, Gu Wenci learned the truth about his origins. Standing at the pinnacle of the world, he looked down upon all living beings, surrounded by countless contracted beasts, each one proclaiming his regal might!
