After Being Rejected 99 Times, I Became the Strongest in the World of Immortality

When he traveled through time and cultivated immortality, the system asked him to confess that he was rejected from increasing his cultivation level. If he was rejected 99 times, he could go home. He carefully planned his 99th confession, but the other party agreed - his cultivation level returned to zero, and his mission became "make her fall in love with you". But every time he breaks out his hidden cultivation, he loses an emotion. The last thing lost is love. He was petrified, and she became the strongest, guarding him for thousands of years.
