One must know, typically, if an Earth Immortal can learn one or two Immortal Techniques, it is already quite impressive.
After all, mastering these techniques is no easy task.
Even if one has the means to learn these techniques, without enough comprehension, it's impossible to even begin.
Even the top Earth Immortals, mastering five or six Immortal Techniques is already extraordinary.
But Zhou Sui, on the other hand, leveraged the power of various Gu Insects to learn many Immortal Techniques.
For example, the Great Shift Technique, Universe in the Sleeve, Great Chaos Thunder Method, Affection of Thirty-Six Lives, Six Yao Divination, Great Wisdom skill, Transform Falsehood into Truth, Great Curse skill, Great Replacement skill, Great Furnace skill, Dragon Elephant Imprison, Hell Gate, Great Poison skill, Great Devouring skill, Great Tracking skill, Great Growth skill, Great Fortune skill, Great Recovery skill, and so on.
