647 I shouldn't have come!

How could Li Yongchang understand? Before coming out, Lin Feng had already laid down more than a dozen Spirit Essence layers in Yang Yuan's hospital room. Although they were not as strong as a Formation, they were more than sufficient to deal with Li Yongchang's Life-bound Gu insect!

For these Life-bound Gu insects to harm Yang Yuan's life was simply a fool's dream!

Since an incident like Chen Changbin's murder had already occurred once before, Lin Feng was of course going to be extra cautious this time.

It was precisely for this reason that Lin Feng disregarded Li Yongchang's threats, because they were not a threat at all!

"Ah------------"

Li Yongchang screamed loudly, his voice becoming hoarse!

When a person is in extreme pain, even a short second can feel like an eternity has passed!

Moreover, at this moment, Li Yongchang felt worse than death itself!
