System, You Really Didn't Lie to Me!

Li Yi Anhanchuang studied hard for 18 years and finally got admitted to the university he wanted to study. But as soon as he stepped through the school gate and traveled through time, he actually traveled through time! Li Yinan:...... But the worst part is that there seems to be something wrong with his system. Other people's systems: Little brother, you must build the foundation of heaven and lay the strongest foundation. Only by practicing in the future can you go higher and higher. Own system: Heavenly Dao foundation building is only temporary, ninth grade foundation building is forever. Come on, young man, follow my brother's footsteps, hurry up! Quick! We only want to practice quickly! Li Yinan:? ? ? ? System: When those geniuses reach the foundation of the eternal heavenly path and you have already formed the elixir, tell Brother Tong, what will they use to fight? You can tell me how to defeat Jindan and Nascent Soul by transcending levels and defeating them? Li Yinan: But if your foundation is so weak, how can you survive the catastrophe? Brother Tong smiled slightly: Who told you that you must resist to overcome the tribulation? In this way, a strange cultivator appeared in the world of cultivating immortals -_-||
