Don't Panic, Her Power Is Infinite

Long Su-Xue is the last immortal in the world. With the Heavenly Tribulation already unleashed, she only needs to pass the final trial to ascend to immortality. Upon first descending to the mortal realm, she was mistaken by the Zhou family for Xiao Lao-Ji's beloved due to a certain estate, leading to doubts about her identity. However, she never knew that all four major families were once her subordinates. On this return, she systematically reclaimed her power and restored order. Yet, the villainess, Lady Xiao, colluded with the city master and a witch to wreak havoc on the human world, even poisoning the entire city and triggering a great calamity. To save the people, Long Su-Xue bravely cut her blood to heal the masses, eventually passing the Heavenly Tribulation and achieving immortality.
