643 Golden Gu King

Although Lin Feng did not know how to use Gu Techniques, he still understood their peculiar characteristics.

Therefore, when he was speaking with Li Yongchang just now, Lin Feng had already released a stream of Spirit Essence, carefully observing the changes around him.

For some reason, Li Yongchang did not launch a surprise attack during their conversation. Lin Feng wondered whether Li had forgotten or simply disdained to ambush him.

However, Lin Feng believed neither possibility was likely; there must have been some other reason unbeknownst to him!

Just now, as Li Yongchang released a faint whiff of smoke containing three tiny Gu Insects that attacked him, Lin Feng's Spirit Essence immediately sensed something amiss and easily captured the three Gu Insects. He then enveloped them in Spirit Essence, cutting off their connection with Li Yongchang and putting them back to sleep!
