He Was Born in His Mother's Womb and Started His Counterattack from Beating the Empress Sister

[System Advance] + [Counterattack System] + [Mother's Fetus] When he woke up, Su Yun was reborn as a fetus in the belly of the Jiang family of the ancient immortal clan. However, the ancestor of the clan wanted to uproot him because he had a weak foundation and would bring disgrace to the family. Fortunately, his father Su Zhantian arrived in time and managed to survive. However, the foundation is weak and he may not be able to survive in the clan. Fortunately, he has awakened the counterattack system. However, this system seems a bit strange... [Ding! The counterattack system is on! [0 Years old, because the foundation is weak, the Su family wants to uproot it, but fortunately your parents insist on keeping you. [1 Year old, although you were born safely, you are only a second-grade water spiritual root, and your talent is of no use. 5 Years old... [Ding! Ask the host to defeat the reincarnated sister of the empress, the time limit is 100 years; system reward: innate Taoist body, growing emperor weapon demon sword blood blade! "A hundred years old? System, I'm not even born yet!" Looking at the task in front of him, Su Yun was confused. He was obviously just an unborn baby! Bite! It is now Tianwu year 7098, and the host is already a hundred years old! "I wasn't born! Can't you see?" Su Yun said helplessly. Bite! Please refer to the system time! "Your sister is sure!" [Ding! Please host civilized language! "I..." Finally, he realized that the system was a hundred years ahead of schedule! Suddenly, Su Yun looked at his sister, the empress, who was also a fetus in the mother's belly, and stretched out his evil right hand to her! Punch it over! The empress sister burst into tears! Bite! Congratulations to the host for completing the mission, the system rewards: Innate Dao Body!
