The System is Forty Years Ahead of Time. I Became a Saint by Completing Tasks.

Thanks for the invitation. I’m in Gaowu, I’m two years old this year, and the counterattack system arrived forty years earlier! [At the age of forty-two, you are the son of the Great Xia Martial Saint, yet you have achieved nothing. Even your martial arts have only reached the fourth level...] [At this age of forty, please try to make the Chinese Martial Saint, who hasn't smiled in thirty years, smile a little.] [Quest Reward: Dao Embryo Pill.] Lu Yu, who was one year and two months old in actual age and two years old in lunar age, looked at the middle-aged man in front of him with a face full of expectation, hesitated for a while, and called out "Dad". The next second, Lu Changsheng, the Martial Saint who was feared throughout Da Xia and suppressed countless alien races, was so happy that he couldn't stop smiling! Lu Yu blinked. Mission... completed?
