"Are you really going to use a wooden bucket?" Mo Wuji chuckled at Wei Zidao.
Wei Zidao replied: "A wooden bucket is the only way you can collect water from the Sword Qi River. Any items smelted from magical treasures would be corroded by the sword qi severely."
His hypothesis was correct. Pang Hong and Shang Hedao had spent hours trying to fetch water from the Sword Qi River and finally found out the trick was to use a wooden bucket.
Wei Zidao subconsciously increased his pace as the strengthened sword qi increased the rate of corrosion
The sword qi present was no threat to Mo Wuji although it was many times stronger than usual. It had not affected his sea of consciousness, but merely injured him physically.
His soul would remain unharmed as long as his sea of consciousness was not affected. Physical injuries caused by the sword qi were inconsequential to him as he was a practitioner of physical tampering.
