The eighth needle!
Lin Xiao felt that the spiritual energy he had just fully recovered was only at forty percent of its capacity.
With this needle, the Dragon Lord's life force completely vanished.
This time, he was dead beyond any hope of revival.
And the faintly visible five-clawed golden dragon on the Dragon Lord's body manifested from within him, transforming into a golden dragon over a meter long that coiled above the Dragon Lord's form.
Was this the True Dragon Qi within the Dragon Lord?
Lin Xiao sensed this True Dragon Qi of the Dragon Lord. Its faint aura was less than a tenth of the golden dragon within himself.
"Xiao Zheng... get out!"
Lin Xiao finally sent Xiao Zheng out of the room with a surge of spiritual energy.
At this moment, the atmosphere in the room changed.
All the Yin energy of the entire hospital converged here.
"Life and Death Needles! Those can truly kill people!" Old Bai's hand trembled as he stared at Qi Tian. "Young man, are you sure? These are the Life and Death Needles?!"
As a Celestial Physician, he was naturally aware of a technique among the techniques of the Underworld Physicians called the Life and Death Needles.
This was also why the Celestial Physicians of the past could never surpass the Underworld Physicians.
The Life and Death Needles could truly achieve resurrection.
However, the conditions for their use were extremely harsh: one needle for death, one needle for life.
The death needle would consume all the innate true qi of a powerful cultivator.
The life needle had to be applied within ten minutes of the death needle's application, otherwise, the death needle would truly become a killing needle.
Ten minutes, how could one possibly recover all their true qi within such a short time? Even a Grand Elixir of Rejuvenation required time to digest its medicinal properties. Therefore, Underworld Physicians generally used another method to activate the life needle.
They used lifespan.
Using life force to replace innate true qi for propulsion, and similarly, life force had to be paid as a price to snatch someone back from the King of Hell.
Historically, there were many instances where Underworld Physicians, to save someone they deemed essential, paid with their lifespan to perform the Life and Death Needles and reclaim a soul from Yama.
Underworld Physicians were true madmen.
In the room, Lin Xiao felt his body was incredibly heavy as he desperately tried to recover his spiritual energy.
The eighth needle had depleted his spiritual energy to the point where he couldn't perform the final needle. It was only after entering the Divine Realm that his recovery speed increased dozens of times; otherwise, he would have had to sacrifice his own life to save the Dragon Lord, just like Xiao Zheng.
He looked at the bottle of Yuan Dan, popping a pill into his mouth.
If nothing unexpected happened, he would recover enough spiritual energy to perform the final needle within five minutes.
But at this very moment...
He seemed to sense something trying to snatch the person away from him.
He stared at the Dragon Lord's body, as the chilling Yin energy began to creep onto it.
"Roar!"
The faint True Dragon Qi let out a growl, as if warning these approaching Yin forces.
It was these roars that made the chilling aura slow down, but only slow down.
The Yin energy was still inching its way up the Dragon Lord's body.
"Without my permission, you are not allowed to take him away," Lin Xiao said word by word, as if talking to himself. Yet, with his words, half of the chilling energy climbed onto his own body.
"Roar!"
The golden light emanating from his Dantian intensified!
