Force could be borrowed and dispelled, but a concealed weapon was no different from a child's toy if there wasn't any strength put in it.
The poison coating the weapon didn't affect Meng Qi in any way. After all, he had already begun training in the Golden Bell Shield's Seventh barrier and had not sustained wounds from weapons of the enlightened level. They didn't use rare poisons or poisonous mists either. How could they possibly poison him?
If the Poisonous Arhat's concealed weapons could threaten his life, then using genuine Qi and mental energy to investigate the enemy wouldn't have been just for show. He didn't practice the type of Peerless Godly Kungfu like the Heavenly Emperor's Scripts, nor was he powerful like Fire Lord, who was nearly capable of the Heaven-man Connection.
Poisonous Arhat collapsed face-first on the ground with a dull thud. Meng Qi leaped over him and dashed into the winding corridor.
