Sign the Contract at the Beginning, I Have Unlimited Contracts with Divine Beasts

[System + multiple heroines + invincibility + combat + time travel + city + mythical beasts + daily life] Gu Wenci is a time traveler from Earth. He accidentally traveled to a world called Tianwu Continent a year ago. After a year of getting to know him, he gradually learned about this world. It turns out that everyone who reaches the age of 18 must start a contract with a monster. The strength of the contracted monster is directly linked to its own value, and the main force is the life of the monster and the main death of the monster. Gu Wenci, who was considered useless on the day of his awakening, contracted with the mythical monster Yinglong. Everyone was so different. Unexpectedly, in this short year, with the help of the system, Gu Wenci had already surpassed everyone present and contracted. With the help of the system, Gu Wenci gradually became stronger, and the women he met on the way fell in love with him unknowingly. But just when he thought he could be safe and sound, even bigger trouble came to his door... Many years later, Gu Wenci learned about his true life experience. He stood on the top of the world, overlooking all living beings, with many contracted beasts surrounding him, all of which showed his qualities as a king!
