During the Investiture of the Gods Tribulation in the ancient era of the Immortal Domain, before Mosquito Daoist had advanced to the Dominator Realm, he took advantage of the chaos of the saints' melee to suck Turtle Spirit Holy Mother, one of Master Tongtian's four great disciples, into an empty husk.
Considering that among Master Tongtian's several disciples, aside from Turtle Spirit Holy Mother and Holy Mother of Wudang, who had perished early for various reasons, all the others had attained sainthood.
Even the Three Heavens Goddesses, whose bodies and souls had perished, had gained reincarnation through the Reincarnation Underworld. Their three true spirits merged into one, becoming the younger sister of Master Tongtian's second life.
Given the talent and ability Duan Ning had displayed, advancing into the Sage Realm in the future would not be difficult for her.
To say nothing else, through the path of "alchemy" alone, even Duan Ning's Senior Brother Xuandu and her master Laozi had praised her without end.
After arriving at the battlefield, Master Tongtian swiftly demonstrated an offensive method as swift as thunder, too fast to cover one's ears.
The Immortal Slaughtering Sword and Immortal Trapping Sword converged like twin dragons, spiraling and dancing as they charged straight at the Mosquito Celestial Emperor.
The Mosquito Celestial Emperor's needle could pierce even ordinary defensive World-Class Secret Treasures, yet before the fierce sword qi of Master Tongtian's Four Swords of Zhuxian, he did not even have the courage to take a hit.
As an old monster who had been renowned in the Immortal Domain for many years, Mosquito Daoist deeply knew the tyrannical, peerlessly overbearing might of Master Tongtian's Four Swords of Zhuxian.
In terms of slaughtering power, there truly were few things in the entire Immortal Domain that could surpass Master Tongtian's Four Swords
