Yushou: Others Spend Their Money, but I Spend My Life!

In the world of beast control, everyone can sign a contract to control beasts and gain powerful power. The stronger the contract is with the beast master, the stronger the beast master's ability will be. Jiang Yu traveled to this world and found that the original owner had contracted a Fengyue Fox. Although Fengyue Fox is not very powerful, as a time traveler, Jiang Yu discovered that he had awakened the Krypton Life System, which could enhance the strength of the pet beast by consuming his lifespan. And he discovered that the life span of this krypton life system can be borrowed! So he borrowed a lifespan of 1,000 years at the beginning and directly let the ancestor of Fengyue Fox evolve into a nine-tailed fox! Relying on this system, Jiangyu is invincible in this world!
